Robust and resilient agrifood systems begin with healthy crops. Without healthy crops the food security and livelihoods of millions of resource-constrained smallholder famers in low- and middle-income countries would be in jeopardy. Yet, climate change and globalization are exacerbating the occurrence and spread of devastating insect-pests and pathogens.
Each year, plant diseases cost the global economy an estimated $220 billion — and invasive insect-pests at least $70 billion more. In addition, mycotoxins such as aflatoxins pose serious threats to the health and wellbeing of consumers. Consumption of mycotoxin-contaminated food can cause acute illness, and has been associated with increased risk of certain cancers and immune deficiency syndromes.
Effective plant health management requires holistic approaches that strengthen global and local surveillance and monitoring capacities, and mitigate negative impacts through rapid, robust responses to outbreaks with ecologically friendly, socially-inclusive and sustainable management approaches.
Over the decades, CGIAR has built a strong foundation for fostering holistic plant health protection efforts through its global network of Germplasm Health Units, as well as pathbreaking rapid-response efforts to novel transboundary threats to several important crops, including maize, wheat, rice, bananas, cassava, potatoes and grain legumes.
On May 12, 2022, CGIAR is launching the Plant Health and Rapid Response to Protect Food Security and Livelihoods Initiative (Plant Health Initiative). It presents a unified and transdisciplinary strategy to protect key crops — including cereals, legumes, roots, tubers, bananas and vegetables — from devastating pests and diseases, as well as mycotoxin contamination. CGIAR Centers will pursue this critical work together with national, regional and international partner institutions engaged in plant health management.
A comprehensive strategy
Prevention. When and where possible, prevention is always preferable to racing to find a cure. Reactive approaches, followed by most institutions and countries, generally focus on containment and management actions after a pest outbreak, especially pesticide use. These approaches may have paid off in the short- and medium-term, but they are not sustainable long-term. It has become imperative to take proactive actions on transboundary pest management through globally coordinated surveillance, diagnostics and deployment of plant health solutions, as well as dynamic communications and data sharing.
To this end, under this Initiative CGIAR will produce a diagnostics and surveillance toolbox. It will include low-cost and robust assays, genomics- and bioinformatics-based tools for pathogen diagnosis and diversity assessment, as well as information and communications technologies for real-time data collection and crowdsourcing. This will be complemented by the development of interoperable databases, epidemiological and risk assessment models, and evidence-based guidance frameworks for prioritizing biosecurity measures and rapid response efforts to high-risk insect-pests and diseases.

Adoption of integrated approaches. The goal of integrated pest and disease management is to economically suppress pest populations using techniques that support healthy crops. An effective management strategy will judiciously use an array of appropriate approaches, including clean seed systems, host-plant resistance, biological control, cultural control and the use of environmentally safer pesticides to protect crops from economic injury without adversely impacting the environment.
Through the Plant Health Initiative, CGIAR will promote system-based solutions using ecofriendly integrated pest and disease management innovation packages to effectively mitigate the impact of major insect-pests and diseases affecting crop plants. It will also implement innovative pre- and post-harvest mycotoxin management tools and processes.
Integrating people’s mindsets. The lack of gender and social perspectives in plant health surveillance, technology development, access to extension services and impact evaluation is a major challenge in plant health management. To address this, CGIAR will prioritize interdisciplinary data collection and impact evaluation methods to identify context-specific social and gender related constraints, opportunities and needs, as well as generate evidence-based recommendations for policy makers and stakeholders.
Interface with global and regional Initiatives. The Plant Health Initiative will build on the critical, often pioneering work of CGIAR. It will also work closely with other CGIAR global initiatives — including Accelerated Breeding, Seed Equal, Excellence in Agronomy and Harnessing Equality for Resilience in Agrifood Systems — and Regional Integrated Initiatives. Together, this network will help support CGIAR’s work towards developing and deploying improved varieties with insect-pest and disease resistance, coupled with context-sensitive, sustainable agronomic practices, in a gender- and socially-inclusive manner.
Targeting localized priorities with strategic partnerships
Effective plant health monitoring and rapid response efforts rely on the quality of cooperation and communication among relevant partner institutions. In this Initiative, CGIAR places special emphasis on developing and strengthening regional and international networks, and building the capacity of local institutions. It will enable globally and regionally coordinated responses by low- and middle-income countries to existing and emerging biotic threats.
To this end, CGIAR will work closely with an array of stakeholders, including national plant protection organizations, national agricultural research and extension systems, advanced research institutions, academia, private sector, and phytosanitary coordination networks.
The geographic focus of interventions under this Initiative will be primarily low- and middle-income countries in Latin America, South and Southeast Asia, and sub-Saharan Africa.
Coupled with CGIAR’s commitment to engaging, mobilizing and empowering stakeholders at various scales across the globe, the Plant Health Initiative represents an enormous step towards integrating people’s mindsets, capacities and needs towards holistic and sustainable plant health management. It will ultimately protect the food and nutritional security and livelihoods of millions of smallholders and their families.

Recently, I published the technical description of Ontology-Agnostic Metadata Schema (OIMS) in the journal Frontiers in Sustainable Food Systems, as part of a special issue on “Agile Data-Oriented Research Tools to Support Smallholder Farm System Transformation.”
CGIAR and the International Maize and Wheat Improvement Center (CIMMYT) are dedicated to providing research data information products (RDIP) in open access, following the FAIR data standards. FAIR stands for findable, accessible, interoperable and reusable. Organizations dedicated to open data have made massive progress in making data findable and accessible. A clear example is a free, open-access repository of research studies developed by CIMMYT scientists. Article 4.1.c.i. of the CGIAR data policy states that “Relevant data assets (e.g. datasets) and metadata shall be interoperable and fit for reuse.”
This is easier said than done. There are well-established standards for descriptive metadata such as the Dublin Core and the derived standard used widely across the CGIAR, aptly called CGcore, used in CIMMYT’s Dataverse research data repository. However, these standards are lacking in many domains for describing the actual content of data sets.
At best, idiosyncratic data dictionaries are developed for specific datasets, projects and sometimes even programs. Idiosyncratic data dictionaries help make data interoperable but, in many cases, require a lot of preprocessing before scientists can actually reuse the data. Having a standard for data dictionaries would be a huge leap forward, but is not likely to happen anytime soon.
The next best thing is to standardize the way that you describe data dictionaries. This was recognized by the community of practice on socioeconomic data of the CGIAR Platform for Big data in Agriculture. Over the past few years, efforts led by CIMMYT set to remedy that lack of a standard, resulting in the flexible, extensible, machine-readable, human-intelligible and ontology-agnostic metadata schema (OIMS).
The paper in the journal Frontiers in Sustainable Food Systems describes a lightweight, flexible, and extensible metadata schema. It is designed to succinctly describe data collected for international agricultural research for development, facilitating interoperability. The schema is also meant to make it easier to store, retrieve and link different datasets stored in a data lake.
Agricultural research data comes to the surface
The paper discusses a need for this type of schema. Typically, agricultural research data comes in different formats and from different sources. For example, we can have structured surveys, semi-structured surveys, mobile phone records and satellite data. In the case of socioeconomic data, it can be particularly “messy.” To facilitate interoperability, we need to find methods to describe these datasets, which are machine readable — or actionable.
There have been other attempts to provide a standardized way to make data interoperable. Past approaches have been comprehensive but cumbersome. That could be the reason why they are typically only used by larger-scale projects. OIMS provides a framework that can be used by all data managers and scientists to enhance the interoperability for research data to ensure the data can be reused with much more ease.
The paper provides a detailed description of OIMS, including: the metadata schema, which describes the data dictionary; and the self-describing metadata, which describes the fields in the metadata. The paper then demonstrates the utility of this schema using a small segment of a household survey.
This paper presents an internally consistent approach to providing metadata for data files when standards are missing. It is flexible and extensible, so it will not be obsolete before it is implemented at scale. The approach is based on the concept of data lakes where data is stored as is. To ensure that data lakes do not become swamps, metadata is indispensable. The OIMS metadata schema approach can help to standardize the description of metadata and thus can be considered the fishing gear to extract data from the data lake.
As part of the on-going work started by the community of practice on socioeconomic data of the CGIAR Platform for Big Data in Agriculture, implementation of the OIMS metadata schema approach on datasets that can create indicators highlighted in the 100Q approach with linkages to the nascent socioeconomic ontology SEOnt is envisaged. This will provide datasets with enhanced interoperability.
With more and more datasets using the OIMS approach in the near future, it will become possible to turn what is currently a socioeconomic data swamp into a data lake. This will provide timely actionable information to support agri-food systems transformation — helping smallholders make a living while staying within planetary boundaries.
Implementing OIMS in practice requires data managers and scientists that collect the data to actively engage in providing the relevant metadata. As mentioned before, some of the metadata can be gleaned from the software solutions the scientists use already. As these are structured metadata, they can be extracted by machines. Often it does require curation by the scientist involved, especially when the software solution does not provide key information that the scientist has at hand but is not documented in a machine-readable way.

Global food prices were already increasing when the world’s wheat supply came under extra pressure, due to Russia’s war on Ukraine. We don’t know whether the farmers who have made Ukraine the fifth-largest exporter of wheat will produce anything in 2022.
Food security is bound to fall, with the greatest impact to be felt by those most vulnerable first. Ukrainians are bearing the worst of it, of course, but the fallout from Vladimir Putin’s cruelty will affect us all.
The problem would be much worse if a remarkable group of scientists had not dedicated themselves in the last century to the improvement of agriculture, in work that continues today and promises to make the future a little more hopeful.
My family witnessed the work of these scientists up close. Our farm is in the state of Tlaxcala, in the highlands east of Mexico City. We grow corn, barley, sunflower, and triticale, which is a hybrid of wheat and rye.
During the 1950s and 1960s, Norman Borlaug brought teams of agronomists to our region as he worked to improve wheat’s germplasm. I wasn’t born at that time, so I couldn’t meet Dr. Borlaug at our farm, but he came many times across several summers. I’ve heard the stories: As my father worked with Borlaug in the fields, growing the seeds that would help Borlaug produce a better kind of wheat, my mother made sure that our house was in order so that Borlaug and his companions had proper accommodations.
Today, of course, Dr. Borlaug is a legend: In 1970, he won the Nobel Peace Prize. Hailed as “the father of the Green Revolution,” he arguably saved hundreds of millions of lives through science-based improvements to the wheat germplasm.
The result is that wheat farmers around the world grow a lot stronger, healthier wheat today. No matter where we live, we’re better able to deal with problems of scarcity.
Drought, disease, and war still possess the horrible potential to inflict suffering, but we’re in fact much more capable of dealing with them because of what Dr. Borlaug and his fellow researchers accomplished decades ago.
Their work continues today at the International Wheat and Maize Improvement Center, also known as CIMMYT (in its Spanish acronym). Founded by the Mexican government and the Rockefeller Foundation, this non-profit group devoted itself to improving the productivity of Mexican farmers. It became the institutional home of Borlaug, whose work was so successful it transformed agriculture not just in Mexico but around the world.
Mexican farmers gained from its work, and so did wheat farmers in India, Pakistan, and elsewhere. In fact, everybody wins: The world has much more wheat today because of Borlaug and CIMMYT.
I’m a special beneficiary, and not just because of my family’s historical connection to CIMMYT. I live within driving distance of CIMMYT’s headquarters, which is a sanctuary of knowledge. It enjoys an amazing history, but also holds a promising future: It remains a resource for improvements in agriculture.
As an agronomist, I always believed that science is a status improver. Because of CIMMYT, I’m a better farmer today than I was just a few years ago, and I’ll be even better in the years ahead.
CIMMYT’s Karim Ammar taught me about triticale, which is producing great results on my farm. As science has progressed and with the conjunction of science and technology, farmers are able to improve productivity and have better soils. Today, Bram Govaerts, who is now CIMMYT’s Director General, introduced me to the value of no-till, which is making my farm both more productive and more sustainable.
Dr. Borlaug’s dying words were “take it to the farmers.” That’s exactly what his successors at CIMMYT are doing. They’re adapting cutting-edge technologies to agriculture. The best part, though, is that they don’t keep their knowledge locked up in labs. They share what they learn with farmers like me, who can apply them to the practical work of food production.
Agriculture will face plenty of tests in the 21st century. The world’s population continues to grow, but our arable land doesn’t increase with it. That means we must continue to produce more food from the farms we already have. At the same time, we must contend with the threat of climate change and make our methods more sustainable, which means preserving biodiversity, conserving water, and kidnapping carbon.
Amid these challenges, Russia’s invasion of Ukraine, a globally important farming nation, is adding stress to the challenge of global food security. As we watch a country and its innocent people suffer, we aren’t thinking much about wheat germplasms—but we should be grateful that CIMMYT’s agronomists have made us all a little more resilient.

The impacts of the Ukraine crisis are likely to reverberate over months, if not years, to come. If the reductions in wheat exports from Russia and Ukraine are as severe as anticipated, global supplies of wheat will be seriously constrained. If a major reduction in fertilizer exports comes to pass, the resulting drop in global productivity will tighten global markets for wheat, other grains and alternate food sources — leaving vulnerable people all over the world facing higher food prices, hunger and malnutrition.
These massive disruptions will erode modest progress made toward gender equality, biodiversity conservation and dietary diversification. The severe impact of this single shock shows the underlying fragility and complexity of our agri-food systems. Climate change will bring many more.
The world must take essential actions to mitigate food shocks, stabilize local wheat supplies and transition toward agri-food system resilience, from the current efficiency-driven model. We call for large and sustained agricultural research investments as a foundational element of any viable, food-secure future.
From chronic challenges to food crisis conditions
Global wheat production for export is geographically concentrated, placing inherent vulnerabilities on the global system. Dominance of the wheat export trade by a relatively small number of countries makes sense under an efficiency paradigm, but it opens the door to price spikes and food-related crises. At the same time, biophysical vulnerability of major global breadbaskets is on the rise as drought and other weather extremes increase volatility in cereal yields, exports and prices.
Russia and Ukraine produce 28% of the world’s total wheat exports and Russia is a globally important source of fuel and fertilizer. With over 2.5 billion people worldwide consuming wheat-based products and wheat futures at their highest levels since 2012, disrupted exports from Russia and Ukraine would usher in substantial new pressures on global wheat markets and tremendous risks for vulnerable populations around the world.
Dependence on wheat imports from Russia and Ukraine imperils food security in lower- and middle-income countries in North Africa and the Middle East (Algeria, Egypt, Libya, Morocco, Yemen), the Mediterranean (Azerbaijan, Turkey), sub-Saharan Africa (Nigeria, Sudan), Southern Asia (Bangladesh, Pakistan) and throughout Southeast Asia. Globally elevated food prices will hit hardest in those countries already struggling with food insecurity.
Layered onto the existing concentration of wheat-exporting countries and the climate-induced vulnerabilities in essential global breadbaskets, the crisis in Ukraine and trade sanctions on Russia are triggering a level of volatility that could easily overwhelm existing mitigation mechanisms. We may well see a range of negative effects over the short, medium and long term, including:
Severe food insecurity and economic impacts due to reduced global wheat supplies and price increases affecting all wheat-importing countries and humanitarian agencies.
Diminished global grain productivity due to fertilizer supply limitations and price escalation, especially in low-income, fertilizer-import-dependent countries.
Higher food prices and expanded global hunger and malnutrition as a result of tighter fuel supplies driving up costs of agricultural production.
Pressure on household budgets negatively affecting nutrition, health, education and gender equity.

Stabilize while building resilience
With these multi-layered challenges in view, we propose essential actions to mitigate near-term food security crises, to stabilize wheat supply and to concurrently transition toward agri-food system resilience.
Without doubt, the world’s top priority must be to mitigate food security crises at our doorstep. This will involve boosting wheat production through expanded acreage (e.g. in high-performing systems in the Global North) and closing yield gaps (e.g. improved management and value chains of rainfed, wheat-based systems in the Global South) using policy incentives such as price guarantees and subsidized agricultural inputs. Short-term food insecurity can also be addressed through demand-side management (e.g. market controls to conserve grain stocks for human consumption; use of lower-cost flour blends) and de-risking alternative sourcing (e.g. trade agreements).
As these actions are taken, a range of strategies can simultaneously drive toward more resilient wheat supply at local to global scales. Well-functioning seed systems, demand-driven agronomic support and other elements of wheat self-reliance can be encouraged through shifts in local policy, regulatory and sectoral contexts. Enhanced monitoring capacity can track spatial patterns in wheat cropping, including expansion into areas where comparative advantage for wheat production (e.g. agro-ecological suitability; supporting infrastructure) has been identified in rural development frameworks and national plans (e.g. as a double crop in Ethiopian midlands). In addition to enabling yield forecasts, surveillance systems are critical to phytosanitary control of geographically restricted pathogens under altered wheat trade routes.
Yet, these steps to mitigate food shocks and stabilize local wheat supplies will not adequately protect the world from climate-related biophysical risks to food and nutritional security. In parallel, a transition toward agri-food system resilience requires transformative investments in agricultural diversification, sustainable natural resource management and low-greenhouse-gas agroecosystems, as well as meaningful actions toward achieving gender equality, nutritional sufficiency and livelihood security.

Sustained research & development for a food-secure future
None of the critical actions described above are guaranteed given the oscillating global investment in agricultural research. Enabled by decades of agricultural research, the world has managed to constrain the number and severity of food security crises through major gains in agricultural productivity.
The International Maize and Wheat Improvement Center (CIMMYT), the global international wheat research Center of the CGIAR, has been working tirelessly to maintain wheat harvests around the world in the face of mounting disease pressures and climate challenges. The estimated benefit-cost ratio for wheat improvement research ranges from 73:1 to 103:1. Yet, research funding only rises when food crises occur, revealing the globalized risks of our highly interconnected agri-food systems, and then tapers as memories fade.
With limited resources, scientists around the world are attacking the complex challenge of increasing agricultural yields and ensuring stable, equitable food supplies. Receiving only about 2% of international agricultural research funding over time, CIMMYT and the entire CGIAR have had limited ability to develop the long-term research capabilities that could mitigate or prevent short-term emergencies with medium- to long-term effects.
Responding to the mounting pressures on deeply complex agri-food systems requires integrative solutions that allow farmers and other agri-food stakeholders to mitigate and withstand shocks and to achieve viable livelihoods. Knowledge and technology needs are extensive across production systems (e.g. wheat-legume intercropping; cereals-focused agroecological interventions), value chains (e.g. context-appropriate seed systems; nutrition enhancement through flour blending), monitoring systems (e.g. genomics-based surveillance), and social dimensions (e.g. gender implications of new production and consumption strategies; policy interventions).
Generating such solutions depends on robust, multidisciplinary and transparent research capabilities that fuel the transition to agri-food system resilience. Robust international investment in resilient agricultural systems is an essential condition for national security, global peace and prosperity.
When wheat prices rise, so do global food prices, along with conflict, inequality and instability. Over the past two decades, the world has witnessed multiple crises erupt over the social and political instability caused by rising costs for staple cereals. The global food crisis that impacted many parts of the world in 2007–2008 was a response, in part, to the prices for wheat and rice which had increased 130% and 70%, respectively, compared to the year before. More recently, spikes in grain prices catalyzed the 2011 Arab Spring.
With the ongoing conflict in Ukraine and the resulting longer-term disruptions of the country’s rural economy, there is potential for another round of turmoil linked to prices for staple cereals.
Wheat is a staple crop, essential to food security. It is consumed by over 2.5 billion people worldwide, including large proportions of the populations of many food-insecure regions in the world. Many of the wheat-consuming countries in these regions are far from wheat self-sufficient, relying on global imports to meet demand. This causes significant vulnerability in food supply and increases associated humanitarian risks. In 2019, important quantities of Ukrainian wheat were exported to low- and middle-income countries in North Africa and the Middle East. Although the impacts of current price increases are anticipated to be short-term, they are likely to be inequitably felt, as not all buyers are able to pay higher prices.
There are over 6 million hectares of wheat planted in farmers’ fields across Ukraine that will be due for harvest in June and July of 2022. The length and depth of the current crisis has potential implications for the fate of this in-field crop, and for its subsequent harvest and global distribution. Likewise, sanctions and trading restrictions on Russia, the world’s largest wheat exporter — exporting $7.92 billion of wheat in 2020 — are likely to place added pressure on international wheat markets. This comes at a time of rising costs in agriculture, including the soaring price of nitrogen fertilizer and increasing fuel and supply chain costs. The gap between supply and demand is also becoming wider with climatic instability — such as drought conditions — hitting both domestic production and export stocks in several countries.
Rising prices for staple cereals have historically led to instability, particularly in fragile regions where food security is low. The impacts of current high wheat prices are likely to be felt most significantly by populations in the Global South who rely on wheat imports.
The potential humanitarian crisis beyond the borders of the current conflict needs to be addressed to avoid deepening global divisions in equality of access to food. In the case of wheat, long-term solutions will require much higher levels of investment, coordination and cooperation between governments, development organizations and agro-industry. Without doubt, part of the solution lies in increasing wheat productivity and profitability in food-insecure regions where wheat has traditionally been grown, as well as supporting the expansion of wheat production into climatically suitable areas in countries which have traditionally relied on imports to meet local demand.
Like many development research and funding organizations, the Australian Centre for International Agricultural Research (ACIAR) is emphasizing a renewed commitment to a nutrition-sensitive approach to agricultural development projects.
In the past decade, awareness has grown about the importance of diets that are rich in vitamins and minerals, and the need to combat micronutrient malnutrition which can lead to irreversible health outcomes impacting entire economies and perpetuating a tragic cycle of poverty and economic stagnation.
Lack of vitamins and minerals, often called “hidden hunger,” is not confined to lower-income food-insecure countries. In richer countries we clearly see a transition towards energy-rich, micronutrient-poor diets. In fact, populations throughout the world are eating more processed foods for reasons of convenience and price. To hit our global hunger and health targets we need to invest in nutrition-sensitive agricultural research and production as well as promoting affordable diets with varied and appealing nutrient-rich foods.
Alongside hunger, we have a pandemic of diet-related diseases that is partly caused by the over-consumption of energy-rich junk diets. This is because modern food formulations are often shaped towards addictive and unhealthy products. We see this in rising levels of obesity and diabetes, some cancers, heart diseases and chronic lung conditions.
Investing in agri-food research and improving nutrition will be much cheaper than treating these diet-related non-communicable diseases. Besides being healthier, many people will be much happier and able to live more productive lives.
Yet, the picture is bigger than micronutrient malnutrition. Even if new investments in research enable us to increase the production and delivery of fruits, vegetables and other nutrient-rich foods such as legumes and nuts, we will not have cracked the whole problem of food security, nutrition and health.
Besides “hidden hunger,” many hundreds of millions of people worldwide are hungry because they still lack the basic availability of food to live and work.
Enter cereals. Wheat, maize and rice have been the major sources of dietary energy in the form of carbohydrates in virtually all societies and for thousands of years: recent research in the Middle East suggests that the original “paleo” diet was not just the result of hunting and gathering, but included cereals in bread and beer!
There are three reasons why cereals are essential to feeding the world:
First, nutritionists and medics tell us that cereals not only provide macronutrients — carbohydrates, proteins and fats — and micronutrients — vitamins and minerals. We now know that cereals are important sources of bioactive food components that are not usually classed as nutrients, but are essential to health all the same. These are compounds like carotenoids, flavonoids, phytosterols, glucosinolates and polyphenols, which are found naturally in various plant foods and have beneficial antioxidant, anticarcinogenic, anti-inflammatory and antimicrobial properties, likely to be important in mitigating and/or combating disease.
Second, whole-grain foods, especially wheat, are also a major source of dietary fibre, which is essential for efficient digestion and metabolism. Fibre from cereals also nourishes the human gut flora whose products such as short-chain fatty acids have many health benefits including combatting some cancers. Eating such carbohydrates also helps us recognise that we have eaten sufficiently, so that we know when “enough is enough.”
Third, cereal foods are relatively cheap to produce and to buy, and also easy to transport and preserve. Hence, supplies are relatively stable, and good nutrition from cereals is likely to remain accessible to less affluent people.
But all is not well with cereals these days. Cereals are under siege from climate change-related heat and drought, and new and more virulent forms of plant diseases, which threaten our agriculture and natural resources. There remains much research to undertake in this era of rapidly changing climatic conditions, and of economic and political stresses.
Here are a few strategies for agri-food research and its supporters:
We can further increase the nutritional content of cereal foods through biofortification during plant breeding.
We can produce disease- and heat-resilient varieties of grains that are efficient in the use of water and fertilizer, and whose production is not labor-intensive.
By working with communities, we can adapt new production technologies to local conditions, especially where women are the farmers.
We can enhance the quality of cereal foods through nutrient fortification during milling, and by better processing methods and food formulation.
Experts in all agri-food disciplines can work together to inform and “nudge” consumers to make healthy food purchasing decisions.
Cereals matter, but in an age of misinformation, we still have to be cautious: Some people are susceptible to certain components of cereals such as gluten. People who are medically diagnosed with cereal intolerances must shape their diets accordingly and get their carbohydrates and bioactive food components from other sources.
So, we cannot live on bread alone: We should aim for diets which are rich in diverse foods.
Such diets include fruits and vegetables that must be accessible to people in different regions, particularly to the most vulnerable, and that provide different macronutrients, micronutrients and essential bioactive components. For most of us, the health-promoting content of cereals means that they must remain a major part of the global diet.

As CGIAR develops 33 exciting new research Initiatives, it is essential for its new research portfolio to move beyond “diagnosing gender issues” and to supporting real change for greater social equity. Gender-transformative research and methodologies are needed, co-developed between scientists and a wide range of partners.
To advance this vision, gender scientists from ten CGIAR centers and key partner institutions came together from October 25 to 27, 2021, in a hybrid workshop. Some participants were in Amsterdam, hosted by KIT, and others joined online from Canada, the Philippines and everywhere in between.
The workshop emerged from gender scientists’ desire to create a supportive innovation space for CGIAR researchers to integrate gender-transformative research and methodologies into the new CGIAR Initiatives.
The organizing team calls this effort GENNOVATE 2, as it builds on GENNOVATE, the trailblazing gender research project which ran across the CGIAR between 2014 and 2018.
GENNOVATE 2 promises to help CGIAR Initiatives achieve progress in the Gender, Youth and Social Inclusion Impact Area. It will also advance change towards Sustainable Development Goals 5 and 10 on gender and other forms of inequality.
In the workshop, participants sought to:
Share and develop ideas, methods and approaches to operationalize gender-transformative research and methodologies. Working groups focused on an initial selection of CGIAR Initiatives, representing all the Action Areas of CGIAR:
ClimBeR: Building Systemic Resilience against Climate Variability and Extremes; (Systems Transformation)
Securing the Asian Mega-Deltas from Sea-level Rise, Flooding, Salinization and Water Insecurity (Resilient Agrifood Systems)
Sustainable Intensification of Mixed Farming Systems (Resilient Agrifood Systems)
Market Intelligence and Product Profiling (Genetic Innovation)
Build on the significant investments, methods, data, and results from the original GENNOVATE.
Conceive a community of practice for continued sharing, learning and collaboration, across and within Initiatives, to accelerate progress on gender and social equity.

Joining a vibrant community
GENNOVATE 2 is envisioned to complement the CGIAR GENDER Platform and the proposed new CGIAR gender-focused research Initiative, HER+.
“We have several gender methodology assets in CGIAR, and GENNOVATE is one of them,” said Nicoline de Haan, Director of the CGIAR GENDER Platform, opening the workshop. “We want to make sure we cultivate and grow the efforts started during GENNOVATE and move forward important lessons and practices in the new CGIAR portfolio.”
The team of scientists behind GENNOVATE 2 wants to support a vibrant community of researchers who “work out loud.” They will document and share their research methodologies, experiences and insights, in order to accelerate learning on gender issues and scale out successes more quickly.
The ultimate objectives of GENNOVATE 2 are to:
Develop and deepen a set of methodologies expected to directly empower women, youth, and marginalized groups in the targeted agri-food systems
Contribute to normative change towards increased gender equality across different scales, ranging from households to countries.
Generate and build an evidence base on the relationship between empowering women, youth and marginalized people, and moving towards climate-resilient and sustainable agri-food systems — and vice versa.
“An example of the added value GENNOVATE 2 can bring to CGIAR Initiatives is understanding what maintains prevailing gender norms in research sites, and also at relevant institutional and political levels,” said Anne Rietveld, gender scientist at the Alliance of Bioversity International and CIAT, and co-organizer of the workshop. “This will enable CGIAR scientists, partners and policymakers to design locally relevant gender-transformative approaches and policies for more impact. We can do this by building on our GENNOVATE 1 evidence base, adapting methods from GENNOVATE 1 and co-developing new methods in GENNOVATE 2.”

What’s next?
The workshop showed that many scientists from CGIAR and partner institutes are motivated to invest in the vision of GENNOVATE 2. Achieving impact in the Gender, Youth and Social Inclusion Impact Area will require concerted efforts and inputs from scientists on the ground.
“There is a groundswell of experience and enthusiasm that you, we, this group brings. We need answers and we can and should work together to make this a reality,” remarked Jon Hellin, Platform Leader – Sustainable Impact in Rice-based Systems at the International Rice Research Institute (IRRI), and co-lead of the ClimBeR Initiative.
The organizing team listed concrete actions to follow the workshop:
Developing processes and spaces for discussing methodological advancements among the gender scientists in these four Initiatives which other Initiatives can tap into, contribute to and become part of.
To develop these shared and integrated methodologies and approaches into a GENNOVATE 2 conceptual and methodological roadmap — to contribute to the CGIAR Gender, Youth, and Social Inclusion Impact Area and guide other Initiatives, as well as bilateral research
To develop a position paper articulating what can be achieved through concerted efforts to integrate gender and social equity more effectively into the Initiatives, to showcase gender-transformative research methods for further development and implementation. The aim of the position paper is to influence global science leaders and CGIAR leadership in how they include issues of social equity in the Initiatives.
To support these conversations, learnings and harmonization processes through setting up a community of practice, where the “practice” to be improved is the practice of advancing gender research methodologies to go from diagnosis to action. This will start with a core group of enthusiastic researchers and then will expand as it gains momentum, so that all researchers in the various Initiatives interested in social equity can contribute
To seek funding opportunities to support the activities outlined above.
The GENNOVATE 2 organizing team welcomes the participation of interested CGIAR Initiatives as they move forward. The organizing team will also help strengthen interactions with external resource people and research networks, in to cross-pollinate new knowledge and innovations.
If you would like to know more about GENNOVATE 2, please contact Anne Rietveld, Gender Scientist at the Alliance of Bioversity International and CIAT and Hom Gartaula, Gender and Social Inclusion Specialist at the International Maize and Wheat Improvement Center (CIMMYT).
The GENNOVATE 2 workshop was supported with funds from the CGIAR Research Programs on Roots Tubers and Bananas, Maize, and Wheat.
Workshop organizers Anne Rietveld (Alliance), Cathy Rozel Farnworth (Pandia Consulting, an independent gender researcher), Diana Lopez (WUR) and Hom Gartaula (CIMMYT) guided participants. Arwen Bailey (Alliance) served as facilitator.
Participants were: Renee Bullock (ILRI); Afrina Choudhury (WorldFish); Marlene Elias (Alliance); Gundula Fischer (IITA); Eleanor Fisher (The Nordic Africa Institute/ClimBeR); Alessandra Galie (ILRI); Elisabeth Garner (Cornell University/Market Intelligence); Nadia Guettou (Alliance); Jon Hellin (IRRI); Deepa Joshi (IWMI); Berber Kramer (IFPRI); Els Lecoutere (CGIAR GENDER Platform); Angela Meentzen (CIMMYT); Gaudiose Mujawamariya (AfricaRice); Surendran Rajaratnam (WorldFish); Bela Teeken (IITA), among others.

In Nepal, agriculture contributes to a third of gross domestic product and employs about 80% of the rural labor force. The rural population is comprised mostly of smallholder farmers whose level of income from agricultural production is low by international standards and the country‘s agricultural sector has become vulnerable to erratic monsoon rains. Farmers often experience unreliable rainfall and droughts that threaten their crop yields and are not resilient to climate change and water-induced hazard. This requires a rapid update of the sustainable irrigation development in Nepal. The Cereal Systems Initiative for South Asia (CSISA) Nepal COVID Response and Resilience short-term project puts emphasis on identifying and prioritizing entry points to build more efficient, reliable and flexible water services to farmers by providing a fundamental irrigation development assessment and framework at local, district and provincial levels.
Digital groundwater monitoring system and assessment of water use options
Digital system of groundwater data collection, monitoring and representation will be piloted with the government of Nepal to facilitate multi-stakeholder cooperation to provide enabling environments for inclusive irrigation development and COVID-19 response. When boosting the irrigation development, monitoring is fundamental to ensure sustainability. In addition, spatially targeted, ex-ante assessments of the potential benefits of irrigation interventions provide insights by applying machine-learning analytics and constructing data-driven models for yield and profitability responses to irrigation. Furthermore, a customized set of integrated hydrological modeling and scenario analyses can further strengthen local, district and provincial level assessment of water resources and how to build resilient and sustainable water services most productively from them.
Toward a systemic framework for sustainable scaling of irrigation in Nepal
Through interview and surveys, the project further builds systemic understanding of the technical, socioeconomic and institutional challenges and opportunities in scaling water access and irrigation technologies. This will contribute to the construction of a comprehensive irrigation development framework, achieved by the collective efforts from multiple stakeholders across different line ministries, levels of government and local stakeholders and water users. Together with the technical assessments and monitoring systems, the end goal is to provide policy guidelines and engage prioritized investments that ensure and accelerate the process of sustainable intensification in irrigation in Nepal.

The COVID-19 pandemic has exposed vast inequalities when it comes to food security. But there is an even larger and more concerning crisis waiting for us: global food shortages caused by climate change.
Nobody knows when or how hard it will hit, but we inch closer each year with new temperature records, the spread of pests, and emerging crop diseases. We are already seeing the beginning of this future crisis. Climate-induced food price hikes have caused political turmoil in the Middle East, while climate-related disasters have been linked with mass human migration in South Asia.
Every seed company and crop research center worldwide is preoccupied with the race to breed hardier crops to keep pace with the demands of a growing population as circumstances become increasingly challenging. But the truth is, this is a relay race, and yet the crop research field is running 100-meter sprints in different places at different times.
For every scientific advance, other areas of crop research go under-resourced and are technology poor, with asymmetries in research investment creating islands of knowledge that are disparate and disconnected. These research asymmetries hold back crop improvement as a whole, contributing to climate-induced crop failure and the political turmoil that ensues when staple foods become scarce.
While it is common for academic crop scientists to share ideas and collaborate with industry, it is far less typical for major seed companies to cooperate with each other.
If the public and private sectors are to have any chance of outrunning climate change, industry must shift toward investing in mutually beneficial research and development to pool resources and build on every gain, in the interests of the whole.
In an unprecedented first step that reveals just how much pressure the sector feels about the daunting task ahead, some of the crop industry’s main players and competitors — including Syngenta, BASF, Corteva and KWS — recently shared their insights into the gaps in existing crop science.
The shortcomings identified that hold back the crop industry from addressing the looming food crisis have three features in common. They are all under-represented in scientific literature, are likely to boost productivity across a wide range of crops and environments, and crucially, the research is fundamental enough to be “pre-competitive,” or valuable without jeopardizing individual business outcomes.
For example, although scientists have made progress towards improving the potential of crucial processes in crop development, like photosynthesis, other gaps in knowledge must be filled to ensure that this translates into improved yield, especially under unstable environments.
Such research is critical to ensuring reliable harvests across a range of crops, and can be conducted without infringing the intellectual property or proprietary technology of any single company.
However, accessing research funding can be surprisingly difficult. Public research budgets are shrinking, their funds are at risk of being re-appropriated, and collaboration is not the industry standard.
New funding models, such as public-private partnerships, can collectively address knowledge gaps to avoid potential catastrophes for society at large.
This approach has already proven fruitful. The public-private consortium “Crops of the Future Collaborative” brings competitors together to jointly fund research into the characteristics crops need to adapt to a changing future.
Industry matched the Collaborative’s initial $10 million investment by the Foundation for Food & Agriculture Research to work on corn that survives in drought conditions and leafy greens that are resistant to pests.
Conducting this research jointly drastically improves crop efficiency and the technological toolbox available to breeders and other crop scientists, passing the baton in the race towards a food secure future.
Increasing the global food supply through research and development is the most achievable and sure approach to avoid a global food crisis, and comes with historically high returns on investment. Furthermore, scientists can tap into a global infrastructure of researchers across public and private sectors, international organizations, and the millions of farmers worldwide who have willingly collaborated over the last half century to provide enough food for all.
Failure to collaborate will ultimately result in unsustainable food systems, which not only renders seed companies obsolete but threatens a prerequisite of civilization: food security.
The private sector has the knowledge and resources to redefine the race. Rather than competing against one another, the crop industry must join forces to compete instead with climate change. And it is a contest we can only win if all players work together.

Artificial Intelligence (AI) and Machine Learning (ML) are increasingly being applied across a diverse range of disciplines. Many aspects of our lives and work are now benefiting from these technologies. Disease recognition, for both human and plant health, is no exception. Ever more powerful AI/ML techniques are now opening up exciting opportunities to improve surveillance, monitoring and early warning for disease threats.
“The value of tools like PlantVillage Nuru is that we can greatly increase the coverage and speed of surveillance,” says CIMMYT scientist and disease surveillance expert Dave Hodson. “Trained pathologists can only visit a limited number of fields at fixed times in the season. With tools like Nuru, extension agents and farmers can all contribute to field surveys. This can result in much faster detection of disease outbreaks, better early warning and improved chances of control”.
New advances in AI/ML technology are now promising even greater improvements in these already powerful tools. CIMMYT scientists have had a long-standing partnership with the PlantVillage group, working to try and develop improved diagnostics for important wheat diseases such as rusts and blast. Considerable progress in developing automated diagnostics for wheat diseases has already been made, but the introduction of advanced image segmentation and tiling techniques promises to be a major leap forward.
“Advances in computer science are constantly happening and this can benefit the mission of CGIAR and PlantVillage,” explains David Hughes, Dorothy Foehr Huck and J. Lloyd Huck Chair in Global Food Security at Penn State and founder of PlantVillage.
“Image segmentation and tiling techniques are a great example. They used to require intensive computing requirements. Now due to advances in computer science these powerful techniques are becoming more accessible and can be applied to plant disease problems like wheat rusts.”
By using these image segmentation and tiling techniques the developers at PlantVillage are now seeing a major improvement in the ability to automatically and accurately detect wheat rusts from in situ photos. “We could not identify rusts with the older approaches but this segmentation and tiling tool is a game changer. The computer goes pixel by pixel across the images which is well suited to diseases like rusts that can be spread across the leaf or stem of the plant. The computer now has a much more powerful search algorithm.”
The team led by Pete McCloskey, lead A.I. engineer at Plant Village, actually used a multi-step process. First they removed the background to help the machine focus in on the leaf. They then digitally chopped the leaf into segments giving the AI a further helping hand so it can focus in and find the rust. Then the whole leaf is stitched together and the rust is highlighted to help humans working in the PlantVillage cloud system.
Fig: Examples of manual, hand labelled images (top rows) compared to AI generated images using segmentation and tiling (bottom rows) for stem rust (upper image panel) and stripe rust (lower image panel).
This exciting new development in rapid, accurate field detection of wheat rusts now needs validation and improvement. As with all AI/ML applications, numbers of images included in the models really improve the quality of the final predictions. “The success of any machine learning model is rooted in the quality and quantity of the data it is trained on,” notes McCloskey. “Therefore, it is critical to source vast and diverse amounts of high-quality images from around the world in order to develop a global wheat rust recognition system.” In this aspect we hope that the CIMMYT global wheat community can help drive the development of these exciting new tools forward.
CIMMYT and PlantVillage are hoping to expand the current wheat rust image dataset and as a result produce an even more valuable, public good, disease detection tool. Given the extensive field work undertaken in wheat fields around the world by CIMMYT staff and partners, we hope that you can help us. Any photos of wheat rusts (stem, stripe and leaf rust) in the field would be valuable.
We would like to have images with one infected leaf or stem per image, it should be vertical in the image so you can see the whole leaf or stem segment. The leaf or stem needs to be in focus and should be roughly centered in the image. It helps to hold the tip of the leaf away from the stem, so it is outstretched and flat. Ideally for training data, the leaf should have only one type of rust and no other disease symptoms. It is okay to have other leaves/stems/soil/sky in the background. It is also okay to have hands and other body parts in the image.
Below are some example images. Any images can be uploaded here.

Back-to-back droughts followed by plagues of locusts have pushed over a million people in southern Madagascar to the brink of starvation in recent months. In the worst famine in half a century, villagers have sold their possessions and are eating the locusts, raw cactus fruits, and wild leaves to survive.
Instead of bringing relief, this year’s rains were accompanied by warm temperatures that created the ideal conditions for infestations of fall armyworm, which destroys mainly maize, one of the main food crops of sub-Saharan Africa.
Drought and famine are not strangers to southern Madagascar, and other areas of eastern Africa, but climate change bringing warmer temperatures is believed to be exacerbating this latest tragedy, according to The Deep South, a new report by the World Bank.
Up to 40% of global food output is lost each year through pests and diseases, according to FAO estimates, while up to 811 million people suffer from hunger. Climate change is one of several factors driving this threat, while trade and travel transport plant pests and pathogens around the world, and environmental degradation facilitates their establishment.
Crop pests and pathogens have threatened food supplies since agriculture began. The Irish potato famine of the late 1840s, caused by late blight disease, killed about one million people. The ancient Greeks and Romans were well familiar with wheat stem rust, which continues to destroy harvests in developing countries.
But recent research on the impact of temperature increases in the tropics caused by climate change has documented an expansion of some crop pests and diseases into more northern and southern latitudes at an average of about 2.7 km a year.
Prevention is critical to confronting such threats, as brutally demonstrated by the impact of the COVID-19 pandemic on humankind. It is far more cost-effective to protect plants from pests and diseases rather than tackling full-blown emergencies.
One way to protect food production is with pest- and disease-resistant crop varieties, meaning that the conservation, sharing, and use of crop biodiversity to breed resistant varieties is a key component of the global battle for food security.
CGIAR manages a network of publicly-held gene banks around the world that safeguard and share crop biodiversity and facilitate its use in breeding more resistant, climate-resilient and productive varieties. It is essential that this exchange doesn’t exacerbate the problem, so CGIAR works with international and national plant health authorities to ensure that material distributed is free of pests and pathogens, following the highest standards and protocols for sharing plant germplasm. The distribution and use of that germplasm for crop improvement is essential for cutting the estimated 540 billion US dollars of losses due to plant diseases annually.
Understanding the relationship between climate change and plant health is key to conserving biodiversity and boosting food production today and for future generations. Human-driven climate change is the challenge of our time. It poses grave threats to agriculture and is already affecting the food security and incomes of small-scale farming households across the developing world.
We need to improve the tools and innovations available to farmers. Rice production is both a driver and victim of climate change. Extreme weather events menace the livelihoods of 144 million smallholder rice farmers. Yet traditional cultivation methods such as flooded paddies contribute approximately 10% of global man-made methane, a potent greenhouse gas. By leveraging rice genetic diversity and improving cultivation techniques we can reduce greenhouse gas emissions, enhance efficiency, and help farmers adapt to future climates.

We also need to be cognizant that gender relationships matter in crop management. A lack of gender perspectives has hindered wider adoption of resistant varieties and practices such as integrated pest management. Collaboration between social and crop scientists to co-design inclusive innovations is essential.
Men and women often value different aspects of crops and technologies. Men may value high yielding disease-resistant varieties, whereas women prioritize traits related to food security, such as early maturity. Incorporating women’s preferences into a new variety is a question of gender equity and economic necessity. Women produce a significant proportion of the food grown globally. If they had the same access to productive resources as men, such as improved varieties, women could increase yields by 20-30%, which would generate up to a 4% increase in the total agricultural output of developing countries.
Practices to grow healthy crops also need to include environmental considerations. What is known as a One Health Approach starts from the recognition that life is not segmented. All is connected. Rooted in concerns over threats of zoonotic diseases spreading from animals, especially livestock, to humans, the concept has been broadened to encompass agriculture and the environment.
This ecosystem approach combines different strategies and practices, such as minimizing pesticide use. This helps protect pollinators, animals that eat crop pests, and other beneficial organisms.
The challenge is to produce enough food to feed a growing population without increasing agriculture’s negative impacts on the environment, particularly through greenhouse gas emissions and unsustainable farming practices that degrade vital soil and water resources, and threaten biodiversity.
Behavioral and policy change on the part of farmers, consumers, and governments will be just as important as technological innovation to achieve this.
The goal of zero hunger is unattainable without the vibrancy of healthy plants, the source of the food we eat and the air we breathe. The quest for a food secure future, enshrined in the UN Sustainable Development Goals, requires us to combine research and development with local and international cooperation so that efforts led by CGIAR to protect plant health, and increase agriculture’s benefits, reach the communities most in need.

The three rust diseases, yellow (stripe) rust, black (stem) rust, and brown (left) rust occur in most wheat production environments, causing substantial yield losses and under serious epidemics, can threaten the global wheat supply.
CIMMYT is one of the largest providers of elite germplasm to national partners in over 80 countries. CIMMYT nurseries, known for research in developing adaptive, high-yielding and high-quality germplasm, also carry resistance to several biotic and abiotic stresses, such as rust disease.
Through years of research and experience, CIMMYT has found that durable control of wheat rusts can be achieved by developing and deploying wheat varieties with complex adult-plant resistance (APR). A combination of both conventional and modern technologies in APR will enable breeders to address the problem of rusts and other diseases and continue progress in delivering higher genetic gains, a key goal of the Accelerating Genetic Gains in Maize and Wheat (AGG) project.
Women represent approximately 43 percent of the world’s agricultural labor. Despite making up less than half of the labor force, women account for 60 to 80 percent of food production in developing countries. Often, official statistics ignore unpaid work – whether in the field, at a home garden or preparing food in the household – thus misrepresenting women’s real contribution to agricultural work and production.
According to the United Nations Food and Agriculture Organization (FAO), if the world’s women farmers had the same access to resources and agricultural financing as men, 150 million people could be lifted out of poverty.
There is no way that we will be able to reach zero hunger if the public and private sectors do not get involved in gender-sensitive programming that addresses women’s access to finance and other resources and opportunities.
A new study supported by the Walmart Foundation, which has been working steadily on this issue, found that smallholder farmers in Mexico must overcome considerable obstacles to access financing – but the barriers to credit are significantly higher for women.
The International Maize and Wheat Improvement Center (CIMMYT) has conducted interventions in the field to support this finding. A multidisciplinary CIMMYT team offered advice on financial inclusion to a group of 1,425 farmers in southern Mexico from 2018 to 2020. The team found that while 331 men received credit, only six women of the same target group did.
Similarly, only three women were able to take out agricultural insurance and 29 opened a savings account after two years of intervention, compared to 110 and 171 men, respectively.
However, there is some hope: an increasing number of farmers, both women and men, is progressively acquiring the basic information and skills to formally request financial products.
CIMMYT obtained funding from the Walmart Foundation in 2018 to implement a project aimed at improving smallholder farmers’ access to markets through collective action, crop diversification, and enhanced access to finance in Mexico’s southern states of Campeche, Chiapas and Oaxaca. The project’s solid results in validation and adoption of sustainable and inclusive technologies were key factors enabling the continuation of activities through 2021.
According to Víctor López, senior manager of partnerships for access to markets at CIMMYT, women farmers are less likely than men to default on loans but seldom have the necessary collateral to be considered as potential clients by standard financial institutions. Without this financial support, they are unable to obtain land, insurance or other critical agricultural inputs, trapping them in a cycle of poverty.
CIMMYT and its partners are working toward a more inclusive approach. With the support of the Walmart Foundation, CIMMYT is strengthening the capacity of farmers – particularly smallholders – and farmer organizations to mitigate production risks and incorporate market-sound considerations into their cropping plans.
These and similar rural development ventures with an inclusive business model perspective can help smallholder farmers, particularly women, combat hunger and food insecurity in Mexico and beyond.
The challenge is to bridge the financial services divide between agriculture and almost every other sector. As economic activity resumes and Mexico gradually recovers from the pandemic crisis, we have a big opportunity to create new credit products and financial services for women farmers that prioritize innovation and sustainable production over ownership rights.
This op-ed by CIMMYT Director General Martin Kropff was originally published in the Mexican Business Review.
At the International Maize and Wheat Improvement Center (CIMMYT), staff are one of our most important assets. We anchor our commitment to diversity and inclusion through our vision, mission and organizational strategy. We interpret workplace diversity as understanding, accepting and valuing all aspects of one’s identity, including gender.
Scientists such as Itria Ibba, head of the Wheat Chemistry and Quality Laboratory, Thokozile (Thoko) Ndhlela, maize line development breeder, and Huihui Li, quantitative geneticist, empower the rest of the maize and wheat research community to do more for those who need sustainable food systems the most.
It wasn’t easy to find a convenient time for the four of us to have a conversation — me, because of COVID-19 travel restrictions, from the Netherlands, Itria in Mexico, Thoko in Zimbabwe and Huihui in China – but we managed. I enjoyed hearing about their work, what sparked — and continues to spark — their passion for maize and wheat research and had the chance to share some thoughts about where the CGIAR transition is taking us.
Martin Kropff, Itria Ibba, Thoko Ndhlela and Huihui Li share a discussion over Zoom. (Photo: CIMMYT)
Martin Kropff: Hello Itria, Huihui and Thoko, great to see you! I’d love to hear more about what you do. Why do you think your work is important in this day and age?
Itria Ibba: Hello Martin! I lead the [CIMMYT] Wheat Chemistry and Quality Laboratory. I am very passionate about my work, which I believe is very important.
In the lab we work both on the improvement of wheat technological and nutritional quality. Both of these aspects are fundamental for the successful adoption of a wheat variety and, of course, to promote a healthy and nutritious diet. Development of nutritious varieties is especially important because — especially in developing countries — the basic diet doesn’t provide all the micro and macronutrients necessary to live a healthy life. Since my focus is wheat, a staple crop that is mainly used for human consumption, I think the work that I am doing can actually have a direct and real impact on the lives of many people.
Kropff: It is important that you — on the quality side of the work — can give feedback to the breeders, and they listen to you. Is it happening?
Ibba: I believe that yes. Of course, quality cannot be the only target in the selection process where several other traits such as yield potential, disease resistance and tolerance to abiotic stresses have to be considered. However, especially for wheat, quality needs to be considered because it is strictly associated with the economic value of a specific variety and plays a fundamental role throughout the whole wheat value chain. The feedback we are giving is being taken positively. Of course, it could be ‘heard’ more.
Kropff: If I may ask, do you think you’re being treated as a scientist regardless of your gender? Or does it matter?
Ibba: Personally, I have always felt that I was respected, in my lab and in my team, especially at CIMMYT. At the beginning, I had some concerns because I am a bit young… Mainly because of that, yes, but not because I am a woman. I cannot say anything bad from that perspective.
Kropff: I think that young people must have the future in our organization. Sometimes when people get older — I try not to be like that, but I am also getting older — they think that they know everything and then you have to be very careful, because the innovations are mostly coming from young people. But young minds come up with new ideas. What about your work, Huihui? You are contributing in a completely different way than Itria and Thoko, and you are coming from a mathematical point of view. When I see you, I always think about math.
Li: Yes, due to my major, sometimes I feel like I am a stranger working in an agricultural research organization. Because I can’t breed new varieties, for example. So, what’s my position? I ask myself: how can I have a successful career in agriculture? But I think that in this new era, this new digital era, I can do more.
Kropff: Data, data, data!
Li: Yes! We can do smart agriculture based on big data. We can do a lot of things with prediction, so that breeders can save time and effort. Maybe we cannot breed the varieties directly or we cannot publish our new findings in high impact journals, but we can play an essential role for this work to be successful. I think that’s my added value: to be useful to breeders.
Kropff: And you are! Thoko, what about you?
Ndhlela: I’m a maize breeder. I’m responsible for two product profiles in southern Africa and these are extra early, early and nutritious maize. I feel like my work is very important, given that I am focusing on developing and deploying nutritious and stress-tolerant maize varieties to people who rely on maize as a staple food crop. White maize is the one that is mainly consumed and yet it doesn’t contain any of the micronutrients such as vitamin A, zinc, iron. We are working towards closing that gap where people have limited or no access to other foods that contain those micronutrients. If we provide them with maize that is nutritious, then we close that gap and addressing the issue of malnutrition. It is especially critical, for young children. According to UNICEF, 53% of the mortalities in children globally are due to micronutrient deficiencies. My work aims to address to a greater extent the problems that farmers face.

Kropff: Are you working on provitamin A maize?
Ndhlela: Yes!
Kropff: It’s orange right? How are consumers adopting it? Does that require extra marketing activities?
Ndhlela: Yes, because in most countries where maize is a popular staple food, people use yellow maize mostly for livestock feeds. But when it comes to the main food, they mainly use white maize. So there has to be that extra effort. We have been working with HarvestPlus on that front, and so far in southern Africa we’ve made good strides in terms of getting people to accept the maize.
Back in the day, when they were first introduced to the idea of eating yellow maize as main food, that maize came from food relief and not in a good state, so there was that negative attitude, which they remembered when we came in with vitamin A maize [which has a yellow color]. We told them, “This is different” and the fact that we did demos, they grew the maize, they harvested and consumed it, led to their acceptance of it. Right now, we have so much demand for seed, especially across southern Africa. Seed companies that we work with say that the seed is sold out and people are still looking for it.
Kropff: I’m very happy to hear this. We have to make sure that what we do is demand-driven, right? And on your role as a woman in research in Zimbabwe. Do you feel like you are taken seriously as a scientist?
Ndhlela: I really do, yes. I am really given space to be myself, to do my work and have that impact on the ground.
Ibba: Martin, I have a question regarding One CGIAR. Will there be any changes within CIMMYT regarding redistribution of research areas? Will some of the research areas change the research focus or implement new research groups and strategies?
Kropff: I could talk for five hours about this. CGIAR has big plans to change the structure, to change the initiatives, to change everything this year.
I believe that CIMMYT is strong, we have a lot of impact. The quality of our work is really high, and I want to make sure that CIMMYT’s work — your work — finds a solid landing in the new CGIAR.
They’re envisioning a restructuring in three large science groups. Several Directors General suggest that we shouldn’t start breaking everything up but that we take whole programs as we have them now and bring them into the new science groups. It’s complicated but everyone wants the CGIAR to be successful.
In terms of research, what we do as CIMMYT already provides solutions, for example, the Integrated Development Programs, such as CSISA, MasAgro, SIMLESA. This has now been taken over by the whole CGIAR. These are programs where you work with national systems and you look at what is important to them, and where innovation is needed. Not focusing on single solutions but integrated solutions from different disciplines. When the research needs come directly from the stakeholders, we become more demand-driven. And that makes life even more exciting.
I think that when we listen to our stakeholders, there will always be a maize and wheat component [in agricultural research]. When we interviewed them in 2020, they stated that things [that are on top of their wish list for agricultural research and development are] breeding, agronomy, big data, and wheat, maize and rice.
I always say: what we need is food systems that deliver affordable — you said it already, Thoko — sufficient and healthy diets produced within planetary boundaries. And for all those criteria, wheat and maize are key because they are efficient, they are produced very well, they provide a good basis of nutrition, and you can produce them within planetary boundaries.
But, back to you. Could you share a story or anecdote about a turning point or defining moment in your work?
Ibba: Personally, I’ve had different turning points that led me to this career but I believe that one of the most important moments for me was when I started my PhD in Crop Science at Washington State University. There for the first time in my scientific career I understood the importance of working together with breeders, molecular scientists, cereal chemists and even with food companies in order to deliver a successful product from farmers all the way to consumers. The research done there had a real impact that you could see and I loved it. Also for this reason, I am happy to now work at CIMMYT because this happens here, as well, but at a bigger scale. You can clearly see that the work and research you do are directly used and go into new wheat lines and new varieties which are grown by different farmers across the world. It’s amazing. That’s what I think had a bigger impact for me.

Ndhlela: I think the biggest moment in my work was when I was first employed as a scientist at CIMMYT. I always looked at CIMMYT scientists as role models. I remember many times that CIMMYT jobs were being advertised for technicians, and people would say, “Oh, this is yours now!” and I told them, “No, no, no, I will only join CIMMYT as a scientist.” And I waited for that moment. And it came and was a turning point in my career and I really thought that now I can express myself, do my work without limitations. And to reach impact!
Another great moment in my work is when I hear that hundreds of farmers are growing and consuming the varieties that I am involved in developing and deploying. I really want to hear people talking of impact: how many tons of certified seed is being channeled from seed companies to the growers, and how many peoples’ lives are we improving. I think that really defines my work. If the varieties don’t get to the farmer, then it is just work going to waste.
Li: Sometimes I feel inferior because I can’t breed a variety, or have big papers in agriculture-related journals, but one day I looked up my citation of my publications and I felt self-satisfied. I could feel my impact. Actually, several of my papers are highly cited; my total citation is more than 3,000 right now.
Kropff: Oh good!
Li: Yes! That means that my work has impact and many people are using the algorithm I developed to have even more impact. Papers that cite my work are published in Science and Nature, Nature Genetics, etc. I feel useful and like my work plays an essential role in research.
Kropff: That’s the thing: there’s impact in science and impact in farmers’ fields and at CIMMYT it comes together. Colleagues at CIMMYT are taking your results and using them to make a difference through crop variety improvement and other things.
Ndhlela: How do you think that One CGIAR will help strengthen our research towards the Sustainable Development Goals across the geographies where we work?
Kropff: I have always promoted the idea of ‘One CGIAR’. Even before joining CIMMYT. But it is complicated because we’re bringing 13 CGIAR Centers together. I saw it at Wageningen University: when you have one organization, you can be so much stronger and more visible, globally.
Because together we [One CGIAR] are the global international organization for agricultural research. We add something [to our global partners such as] the Food and Agriculture Organization of the UN (FAO) which works on agricultural policy, and IFAD that has international development programs and World Food Programme which delivers food — most of it staple crops — to those who need it the most. But supplying food is not a sustainable approach, we want to have sustainable food systems in those countries, so that people can produce their own food. That’s where research is necessary, and knowledge is necessary.
I am super proud that the wheat and maize and agronomy work we do is so well adopted. Farmers are adopting our varieties across the globe. These are new varieties I’m talking about — this is key — which are on average 10 years old and they respond to current challenges happening on the ground. Regarding your work, Thoko, with maize, I just got data from Prasanna [CIMMYT’s Maize Program and CGIAR Research Program on Maize Leader, Prasanna Boddupalli] that farmers are growing drought-tolerant maize and other maize varieties from CIMMYT on 5 million hectares in eastern and southern Africa! All of this is because of a good seed systems approach with the private sector: small seed companies delivering our varieties scaling our great breeding work. Taking it to the farmers!
I think that the work that we do is super important to reach the Sustainable Development Goals. Number one —– well, it’s number two, but for me it is the first —– is ending hunger. Because when you’re hungry, you cannot think or live normally. Poverty is also an incredibly important challenge. But I would put hunger as number one. I don’t think any of us here have had real hunger. My parents did, in the Second World War and let me tell you, when I heard those stories, I realized that that’s something that nobody should go through.
Climate change as well. We have to keep innovating because the climate keeps changing. I was just reading today in a Dutch newspaper that 2 degrees won’t be reached, it will be more. And in the Netherlands the land is so low, so that even with dykes, we will not be able to manage in the next 50 years. People will have to start moving. In the Indo-Gangetic Plains, they’ll have to plant short duration rice, use smart machinery such as the Happy Seeder, then plant short duration wheat — all just to stay ahead of the looming 50 ˚C weather.
Do you agree?
Ibba: Well, yes, but I hope that in the end there will be good coordination between the CGIAR Centers and everything. But if it works well, then I definitely think that it will be more impactful. That’s for sure.
Kropff: What can supervisors and mentors do to encourage women in science careers?
Li: I think this is a good question Martin. I am sure that Itria and Thoko will agree with me: women need more than just our salary. I think that women are more emotional, so, most of the time, when my supervisor is more considerate and careful in regard to my emotions, I feel touched and actually, more motivated. I simply need more consideration, emotionally. I have some experience in this with students [who work for me]. When I want to stimulate their motivation, I compare the two effects. Say, I increase their salary. I feel that the male student is happier than the female. [Laughs] On the other hand, I try to be more considerate with all of my students and ask them about their families or express concern about something. When I do this, I don’t get much of a reaction from the males but the females are grateful. I think the same works for me.

Kropff: I always intend to treat everyone equally and I think I do. But then some people need to be treated differently. That is situational management based on the capabilities and also the personality of people. Do we have to be more mindful of how one works with women?
Li: Well, people are diverse.
Kropff: Right. On the one hand, people should be treated as they want to be treated based on their individual personality, and then on the other hand you want to make sure that women are taken as seriously as men in, say, science.
Ndhlela: I agree with Huihui. Supervisors should give maximum support to women because they already have full plates. The field of science is challenging, so if they feel that they’re not being given enough support, they tend to get discouraged and demoralized. So, supervisors and colleagues need to take that into account. Like Huihui said, women are more emotional than our counterparts. And they need that support. When dealing with women in a professional setting, supervisors could take a visionary style where they give us space to work and do our assigned duties without a lot of interference. Micromanagement is frustrating. From my experience, women in science are serious and they can work with minimum supervision and they are really out there to achieve objectives.
Ibba: I agree with both of you. Space and trust, and constructive criticism. Apart from the strength and support from one’s supervisor, it would be good to implement a mentorship program for young scientists. Sometimes you need a non-supervisor voice or someone that can guide you [who you do not report to]. Human Resources also need to play a key role in supporting women and men, and ensuring zero discrimination. But I’m sure that all we really want is to be treated as humans [laughs]. We all have emotions.
Kropff: Thank you very much colleagues for this open discussion. This has been very interesting and given me a lot of food for thought. Our conversation makes me miss pre-COVID-19 informal moments at work and at conferences, social moments where people open up. But here we show, we can do that during Zoom meetings as well with videos on to read each other’s body language and with groups that are small. Thank you for the inspiration!

In 1966, the International Maize and Wheat Improvement Center (CIMMYT) hosted a training event that was unlike any class the students had attended before. The students came from all over the world, the classroom moved between different environments in Mexico, and their teacher was Norman Borlaug. Over the course of 6 months, national agricultural partners, graduate students, and future research leaders from all over the world studied under Borlaug, one of the most famous and impactful agronomists in history.
Since its inception in 1966, the CIMMYT Global Wheat Program (GWP) annual training has hosted more than 1700 scientists from 99 countries. The aim of this program is to improve the breeding skills and research capacity of national partners, research staff and graduate students from countries where wheat is a major staple food crop. Along the way, the researchers expand their professional networks and share experiences in agronomy from around the world.
The CIMMYT GWP training program staff recently caught up with some graduates from the course to find out what their biggest takeaways were from the experience.

Meet the students
Muhammad Ishaq, a senior research officer working in wheat breeding at the Barani Agricultural Research Station (BARS) in Pakistan participated in the training program in 2019. The most important lesson he brought home was that the success of a wheat breeding program depends on problem-based breeding for target environments. He will always remember the interactions with CIMMYT scientists during his stay in Mexico. “This is a clear example of working together in partnership for global impact,” said Ishaq.
Lezaan Hess, a young academic and plant breeder at Stellenbosch University in South Africa participated in the program in 2019. Lezaan emphasizes the importance of this training in starting her professional career and says she will always remember the hard work and dedication of the CIMMYT wheat breeding teams. “It will keep inspiring me to work hard, stay committed and dedicated, and to collaborate to achieve greater success in the fight against world hunger,” said Hess.

Vijay Dalvi, a young professional at DCM Shriram LtD in India, attended the training program in 2013. His biggest takeaway from the training period was improving his knowledge on selecting individual plants in early generations, rust scoring and selecting grains. “The training not only helped us understand wheat breeding, but also showed us how to work in a team,” he said. “I am still replicating CIMMYT’s way of work at my current organization, and am sharing data from CIMMYT trials to discuss ideas.”
Saima Mir, a 2017 participant, currently works as a senior scientist with the Nuclear Institute of Agriculture (NIA) in Pakistan, where two new CIMMYT-derived wheat varieties with tolerance to water-stressed environments were released in 2020. Mir was very enthusiastic about her experience in the training program.
“I wish I would have received this training at the beginning of my research career,” she explained. “[It] was a combo of conventional and highly advanced breeding techniques, lectures and hands-on practice in the laboratories, green houses and in the field.”

Dario Novoselovic, who is now a senior researcher at the Agricultural Institute Osijek in Croatia, attended the wheat training course in 2000. Novoselovic said he particularly enjoyed the immersive nature of the training, saying that it paved the way for his future professional career. “We were among the lucky generations [with] the opportunity to interact with and enjoy the lectures from Dr. Borlaug, you can imagine the kind of feeling and spirit [we had] after his lectures,” he said.
Sundas Waqar, who works as a scientific officer for the National Agriculture Research Centre in Islamabad, Pakistan, recalls the technical training in the CIMMYT program. “The training provided me the opportunity to connect with the world. I got promoted to my current position after completing training at CIMMYT.”
Naresh Kumar, a senior wheat breeding scientist in the Genetics Division at the Indian Agricultural Research Institute (ICAR) in New Delhi, India, took the course in 2019. “I am utilizing all the skills in my research and management activities. Collaboration with CIMMYT scientists is now quite direct and friendly,” he explained. “A key lesson was sharing knowledge and experience with partners across the world.”
A different experience for 2021
This year, CIMMYT’s signature training program looks quite different as both students and trainers navigate challenging travel and safety restrictions due to the pandemic. Since on-site training this year was not possible, GWP decided to continue these capacity building activities as many other schools have: virtually. The 2021 Basic Wheat Improvement Course went online on January 18, and — echoing the spirit of its far-reaching legacy — 68 participants from 21 different countries will still receive training this year.
