CIMMYT has several offices in the Americas, including global headquarters in Mexico and a regional office in Colombia. Activities are supported by an additional 140 hectares of stations in diverse agro-ecological zones of Mexico. CIMMYT’s genebank in Mexico stores 27,000 maize and 170,000 wheat seed collections – key to preserving the crop genetic diversity of the region. CIMMYT projects range from developing nutritionally enhanced maize to mapping regional climate change hot spots in Central America. The comprehensive MasAgro project aims to increase wheat production in Mexico by 9 million tons and maize production by 350,000 tons by 2030. CIMMYT promotes regional collaboration and facilitates capacity building for scientists, researchers and technicians.

Andrea Gardeazábal has many titles — Monitor, Evaluation and Learning Manager, ICT for Agriculture — but the core of what she does is knowledge management. She merges monitoring, evaluation, accountability and learning (MEAL) with information communication technologies (ICT) to transform data into something meaningful.
A political scientist by training, Gardeazábal knows the power of data and statistics. As she began working on ICT-for-development projects in the field, she observed a lack of understanding of ICT and how the development sector could take advantage of these tools.
“I knew this was progressing very fast; that this was the future. Everyone was talking about ICT and the future with the internet of things, and social media was just getting started,” she said. So she asked herself, how could the development sector take advantage of these new technologies?
Gardeazábal was working on projects bringing computers to rural areas in Colombia, which did not have internet connection or electricity. The problem could not be solved simply with a machine. She wanted to understand how to use ICT for development in a meaningful way. This triggered an interest in MEAL, to understand how ICT benefits the development sector, or does not, and to reintegrate that information into project design and impact.
After working in ICT for civil participation, education and microfinance, she joined CIMMYT with the mission to understand ICT for agriculture. Now she merges ICT tools with MEAL, leading the design, development and operation of systems for data collection, data cleaning, data analysis and data visualization with the Integrated Development program’s projects in Colombia, Guatemala and Mexico.
Ensuring intended results
Monitoring, learning, accountability and evaluation is crucial to ensure CIMMYT delivers on its objectives. Monitoring means ensuring that operations in the field are happening as planned. Rather than waiting until the end of the project when the donor asks for a report, Gardeazábal’s team monitors operations in the field on a quarterly or yearly basis. The team, both in the field and at headquarters, uses this data to check that the project is achieving what was intended and make interventions or adjustments if necessary.
Evaluation looks at project results and evidence. The team collects evidence for every single data point that they have, and then evaluates that evidence for impact and results in the field. This data is not only related to yield increase, but includes sustainable production, capacity development, and adequate technology adaptation and adoption processes.
Accountability is transparency with funders, so that everyone involved in a project is accountable for the processes, decisions and impact. CIMMYT is able to show progress through a transparent relationship with funders.
Learning happens after the team collects information, produces results evaluations, and understands what was done well and where the process had to be redirected. This information can then inform design of new projects or project phases. “We use the data and analysis of each project to redesign or modify our plans for the next project or even what kinds of projects we want to conduct,” Gardeazábal said.

What ICT can offer
In the past, a MEAL team would collect data from a representative sample at the start of the project, then go back to the office and analyze that data. At the end of the project, the team would complete the same exercise, to see the difference from what they gathered at the beginning.
With ICT tools, researchers are able to gather and analyze robust data more quickly and can communicate efficiently with the beneficiaries of a project throughout its course. Artificial intelligence and machine learning algorithms can help in understanding large sets of data so that this information can strengthen and streamline the MEAL process and project impact.
“We don’t need to wait until the end of the project for the results in the field or to have a sense of what the farmers are saying and achieving. We have a lot of tools, from the ICT side, that help make monitoring and evaluation more efficient,” Gardeazábal explained.
An international award recognized some of these ICT tools earlier this year. Gardeazábal formed part of the winning team with members from the Alliance of Bioversity International and CIAT and the International Institute for Applied Systems Analysis (IIASA) working on groundbreaking data systems and tools that help over 150,000 farmers in Mexico.
The team tracked over 500 variables over different farming plots and analyzed them with geographic, weather and market data to help identify the best management practices for each plot. This information — including historic yield potential, local benchmarks, windows of opportunity, recommended agricultural practices and commodity price forecasting — is available to farmers through an app called AgroTutor (Android, iOS).
The importance of an enabling environment
However, Gardeazábal cautions against the idea that technology on its own is going to end poverty or increase food security.
“ICT is a vehicle for innovation in agriculture. Just having an app in the field is not enough to generate the change that we are actually looking for. You need an enabling environment, a network, engagement of the farmers and the buy-in of scientists to take advantage of ICT tools.”
From drones and satellite imagery to artificial intelligence, ICT tools can help CIMMYT carry out its mission by streamlining the data gathering and analytics processes.
However, this work is not done in isolation from the environment surrounding it. CIMMYT does not only work on increasing yields, but also manages resources and local networks in efficient ways. Teams must monitor data on air quality, water use and efficient information flows, analyze this data, and then return to the field with recommendations for the most sustainable production within integrated agri-food systems.
In the early days of organizations like the International Maize and Wheat Improvement Center (CIMMYT), the answer to improving global food security was obvious. Help people grow more food. Today the situation is far more complex. Many exciting developments in breeding are either protective or corrective in nature. Stress-tolerant seed varieties are meant to help protect against the worst effects of global climate change. Efforts to develop widely cultivatable, high-yielding varieties based on local landraces seek to reintroduce some of the biodiversity lost through the runaway success of just a handful of commercial varieties.
Yet problems of food insecurity and poverty persist, not least among smallholders. The good news is that it is precisely among these farmers that important gains remain to be made, especially if we consider the many steps from planting to final consumption where technical and processual improvements can be made. “Just having a seed is not sufficient,” said CIMMYT postharvest specialist Sylvanus Odjo. “Of course having good seed is important, but you also need good agronomic practices.”
Globally, Odjo pointed out, one third of agricultural production is lost in the postharvest phase. In tropical Mexico, postharvest losses among smallholder maize farmers can reach up to 40%.
As the recently published findings of a two-year-long research project led by CIMMYT researchers show, such losses are entirely avoidable. The study, which was conducted in 2017 and 2018 across dozens of sites in Mexico representing a broad range of altitudes and ecologies, tested multiple storage technologies to determine which are most effective at avoiding postharvest losses using real-world smallholder practices and regardless of climatic and environmental factors.

Researchers compared storage outcomes using conventional methods such as storing untreated maize in 50 kg polypropylene bags, storing maize in polypropylene bags and treating it with one of various agents — including aluminum phosphide, deodorized malathion or inert dusts — and hermetic storage options such as hermetic metal silos, two types of GrainPro hermetic plastic bags, and low-cost alternatives like plastic bottles and silage bags.
Under controlled conditions, they found that loss outcomes were highly variable for conventionally stored maize, with or without treatment agents. While untreated grain stored in polypropylene bags in temperate conditions at Texcoco only exhibited only 2.2% insect-damaged maize, grain treated with aluminum phosphide and stored in conventional bags in tropical conditions at Cotzocón suffered 46.3% insect damage.
In contrast, maize stored in low-cost hermetic alternatives such as plastic bottles and silage bags exhibited a maximum of 1.2% insect-damaged grain across all sites. Hermetic metal silos and GrainPro bags performed similarly well across climates, with a couple of important exceptions. The percentage of insect-damaged grain for maize stored in hermetic metal silos at Zacaultipán was 13.5%. Maize stored in GrainPro bags at this site suffered 8.1% insect damage.
Overall, the study convincingly demonstrated the effectiveness of hermetic storage technologies at minimizing insect and mycotic damage as well as weight loss of stored maize regardless of climate or altitude. However, important obstacles to the effective adoption of the technologies remains. In the case of the hermetic metal silos, it was determined that despite the existence of a stringent national norm for their construction in Mexico, silos occasionally did not meet the national standard and had to retrofitted to ensure hermeticity. And, as the example of Zacaultipán demonstrated, poor pre-storage processing of grain can compromise the effectiveness of hermetic storage technologies.

Over the course of carrying out the experiment, the researchers discovered other challenges. In Mexico, as is often true among smallholders globally, women are largely in charge of postharvest activities. “But we noticed that it was largely men who showed up to the trainings,” Odjo said. Researchers had to think of strategies—from being more careful about meeting timings to enlisting the support of local women leaders—to ensure that the trainings were reaching the women who actually carry out this work.
As Odjo pointed out, resolving these kinds of implementation and advocacy challenges—from ensuring adequate training and familiarity with the technologies on the ground to encouraging public and private sector partners to make the technologies more broadly available—is the next step for the project. “The less complex part of this work is the technical part,” he said. “Our job now at CIMMYT is to bring these innovations to farmers… We need to get all the relevant stakeholders involved in the game.”
The project was carried out in partnership with the Mexican government via MasAgro, and received funding from the CGIAR Research Program on Maize (MAIZE). Its implementation involved collaboration with dozens of local partners throughout Mexico and was carried out in response to the suggestions of smallholder farmers.
For three years, Kellogg, in partnership with the International Center for the Improvement of Corn and Wheat (CIMMYT), has been working on a program which seeks to provide technical and scientific advice to increase the productivity of land and efficient use of available natural resources, so farmers obtain better crops and have more profitable economic activities that mitigate the effects of climate change.
With global agriculture in stasis and under threat from climate change, Latin America’s role to address these challenges through innovation and partnerships is crucial. This was the main takeaway from a 2020 World Food Prizeroundtable event, where representatives from four CGIAR centers discussed opportunities for increased investment in Latin America for developing innovations to improve global agriculture and agro-biodiversity.
The event was moderated by Natasha Santos, the Vice President of Global Stakeholders Strategy and Affairs for Bayer Crop Sciences. Speaking online from Brazil, Santos stressed the importance of private sector partnerships in Latin America for achieving sustainable growth and development.
Jesus Quintana, the Managing Director for the Americas, the Alliance of Bioversity International and CIAT opened the event with a short description of his organization’s work with development finance to promote sustainable development in the Amazon. “With USAID,” he said, “we are searching for business models that strengthen local innovations and social businesses to conserve biodiversity, including agri-food systems.”
Picking up on the idea of agri-food systems, Bram Govaerts, Interim Deputy Director General, Director of Integrated Development and Representative for the Americas, International Maize and Wheat Improvement Center (CIMMYT), noted that the World Food Programme will receive the Nobel Peace Prize 50 years after Norman Borlaug – whose work was the inspiration for the CGIAR – became the first recipient of the prestigious award from the fields of food and agriculture. The span between awards, Govaerts said, serves as notice that much important work still remains in the fight against hunger and nutrition insecurity worldwide.
In this vein, Govaerts described CIMMYT’s work with a program called AgroTutor, which delivers site-specific data and recommendations tailored to farmers’ needs that help improve yields and facilitate more profitable market interactions.
The continuing mission to eradicate global hunger and promote development in the face of climate change can be uniquely addressed in the Andes, said Ginya Truitt Nakata, Regional Director for Latin America and the Caribbean, International Potato Center (CIP). Home to 85 of the world’s 110 biological life zones, Truitt Nakata said CIP’s Andean Initiative would use the mountains as a living laboratory for co-investigation of agricultural challenges with networks of smallholder farmers.
“The data and lessons we draw from these spaces will have application for farmers around the world,” she said.
As the event centered around recent CGIAR innovations in Latin American, Ruben G. Echeverría, Senior Research Fellow, International Food Policy Research Institute (IFPRI), said the greatest need, system-wide, is the bottleneck of ideas and innovations prior to implementation. For this reason, IFPRI is developing project incubation facilities to scale up innovations for stronger, further-reaching impact with farmers. “This work requires partnerships with public and private finance to help transform our knowledge into impact for food systems,” he said.
Following the short presentations, the roundtable opened a conversation that focused on the need for inclusiveness in research, private sector partnerships, and data collection supported by monitoring and learning.
“As the CG system, we are talking about participatory development with farmers – women, men and youth. It takes a little longer but the adoption rates [of innovation] are much higher,” Truitt Nakata said.
Agriculture in Latin America, like other regions of the world, also struggles with “brain drain,” losing talented young people to other sectors of the employment market. “So, when we talk about youth,” Echeverría responded, “We need more than participation. It’s about attracting young people to agricultural opportunities through IT and finance.”
Focusing on the technical side of innovation, Govaerts and Quintana cited the need for improved use of data.
“We need to multi-purpose data and use monitoring in real time to ensure better return on investment,” said Govaerts, “We need to know where we made progress and where we made mistakes.” Quintana endorsed that sentiment, “Careful monitoring of projects should be the heart of collaborative work, to generate baselines so we can accurately measure our impact and make more responsible use of resources.”
Given the wealth of ideas exchanged in the hour-long event, Marco Ferroni, the Chair of the CGIAR System Management Board, said the presentations showed the indispensable value of the region’s to food system and agrobiodiversity research.
“Latin America is the world’s largest food exporting region and important producer of ecosystem services that shape global weather patterns and climate… Motivated by the need to increase the scope of our impact, partnerships help us achieve critical mass in terms of data, analysis and delivery to stakeholders. For all these reasons, and others, Latin American food systems need and deserve policy attention and investment,” Ferroni said.
The World Food Prize Foundation is honoring the work of Rattan Lal, who dedicated his life to study the effect of soil health in food production and climate change mitigation. On October 15 he will receive the 2020 World Food Prize, considered the “Nobel Prize” of agriculture.
Lal, who serves as distinguished professor of Soil Science and founding director of the Carbon Management and Sequestration Center at Ohio State University, is a visionary who understood the intricate relationship between soil conservation, yield potential, nutrition and carbon sequestration.
“Dr. Lal’s innovative research demonstrated how healthy soils are a crucial component of sustainable agricultural intensification — enabling higher crop yields, while requiring less land, agrochemicals, tillage, water and energy”, announced the World Food Prize Foundation in a press release.
Lal becomes the 50th person to receive the World Food Prize since the late Norman Borlaug — 1970 Nobel Peace Prize laureate — established the award in 1987. The award acknowledges outstanding contributions to human development by individuals who significantly improve the quality, quantity and availability of food on a global scale.
“CIMMYT actively researches and promotes the sustainable farming practices that Dr. Lal studied and advocated for since the late 1980s, such as no tillage, residue retention and crop rotation, which combined with new precision farming technologies help farmers increase yields, reduce food production costs and protect the environment”, said Bram Govaerts, Integrated Development director and representative for the Americas at the International Maize and Wheat Improvement Center (CIMMYT).

Alison Bentley, who will be joining the International Maize and Wheat Improvement Center (CIMMYT) next month as director of the Global Wheat Program and the CGIAR Research Program on Wheat, joined wheat research colleagues at the Borlaug Global Rust Initiative Technical Workshop last week to introduce herself and offer her perspective on current prospects for wheat research.
Bentley, who currently serves as director of Genetics and Breeding at the National Institute of Agricultural Botany in the UK, emphasized the efforts of CIMMYT and partner scientists in the Accelerating Genetic Gains in Maize and Wheat for Improved Livelihoods (AGG) project.
“AGG is unique, and it’s something that’s really close to my heart in harnessing innovations and deploying them in breeding to deliver genetic gains,” she said.
Bentley gave workshop attendees a sneak preview of new speed breeding facilities in CIMMYT’s Toluca experimental station, which will help wheat breeders reduce cycle time, saving costs and getting high yielding, improved varieties tested and in farmers’ fields more quickly.
“There has never been a more exciting time to be involved in wheat research and breeding,” she told the gathering.
See Alison Bentley’s full presentation from the BGRI Technical Workshop below.
Accelerating Genetic Gains in Maize and Wheat for Improved Livelihoods (AGG) is a 5-year project that brings together partners in the global science community and in national agricultural research and extension systems to accelerate the development of higher-yielding varieties of maize and wheat — two of the world’s most important staple crops. Funded by the Bill & Melinda Gates Foundation, the UK Foreign, Commonwealth & Development Office (FCDO), the U.S. Agency for International Development (USAID) and the Foundation for Food and Agriculture Research (FFAR), AGG fuses innovative methods that improve breeding efficiency and precision to produce and deliver high-yielding varieties that are climate-resilient, pest- and disease-resistant, highly nutritious, and targeted to farmers’ specific needs.

With sorrow we report the passing of Donald Winkelmann, who served as Director General of the International Maize and Wheat Improvement Center (CIMMYT) from 1985 to 1994.
During his tenure, CIMMYT expanded notably and gained recognition as a research center committed to sustainable agricultural development. Winkelmann successfully negotiated CIMMYT’s final status as a public international organization.
The Center’s first economist, Winkelmann arrived in 1972 to conduct and coordinate what became a landmark series of adoption studies on emerging maize and wheat technologies from CIMMYT. He established CIMMYT’s Economics program and served as its first director.
In his first address as Director General, he emphasized that, when competing against “new forces” and technological changes “the old personality of CIMMYT must endure — the commitment to excellence and action, and to the ideal of making things better.”
Winkelmann was appointed for a second term as Director General by the Board of Trustees in 1990.
On November 23, 1994, he received the Order of the Aztec Eagle — the highest distinction given to a foreigner by the Mexican government. During the award ceremony, the Under-Secretary of Foreign Relations of Mexico, Ambassador Andres Rozenthal, highlighted three stages of Winkelmann’s contributions to Mexico. First, as visiting professor of economics at the Post Graduate College (1966-1971), where he helped train Mexican agricultural economists with new tools and methodologies. Second, as founder and director of the Economics program at CIMMYT (1971-1985), where he addressed themes such as on-farm research and comparative advantage studies, generated research methodologies, and carried out training workshops in agricultural economics. Lastly, as Director General of CIMMYT (1985-1994), where he helped strengthen collaboration between CIMMYT and Mexican research institutions, while working on allocation of resources to research, strategic planning and research impacts.”
After retiring from CIMMYT in November 1994, Winkelmann accepted the appointment of Chair of the CGIAR’s Technical Advisory Committee (TAC).
The CIMMYT community sends its warmest condolences to the Winkelmann family.

CIMMYT researcher Bram Govaerts participates in the World Food Prize and Borlaug Dialogue.
The director of the Integrated Development program and Representative for the Americas at the International Maize and Wheat Improvement Center (CIMMYT), Bram Govaerts, has been elected as Fellow by the leading professional organization of agronomists in the United States.
The American Society of Agronomy (ASA) presented this award to Govaerts for his outstanding contributions to the field of agronomy.
“His initiatives, excellence in science for impact and the partnerships he inspired have resulted in improved nutrition, nature conservation, and national and international resilience and food security”, announced the ASA in a news release.
Being an ASA Fellow is the highest honor offered by the organization, with only 0.3% of active and emeritus members holding this distinction.
The awarding body recognized Govaerts as an international authority in maize and wheat cropping systems who works for a successful transition to sustainable intensification of small-scale farming in Africa, Asia and Latin America.

“Bram engages from the field in a remote village all the way up to the office of the president, and from livelihoods and social inclusion to science and business development, in a tireless effort to generate systems change creating sustainable agri-food systems for nutrition, nature conservation and peace,” said Sanjay Rajaram, ASA Fellow, 2014 World Food Prize Laureate, distinguished scientist and retired CIMMYT Wheat Program director, who nominated Govaerts to the ASA’s Fellows Committee.
“I am honored and grateful for receiving this award which shows, above all, that CIMMYT stands for impact and sound science that saves millions of lives, a duty to humanity that we must never compromise,” Govaerts said.
Born in Belgium, Govaerts studied Bioscience Engineering at K.U. Leuven, where he earned a master’s degree in the same subject with specialization in Soil Conservation and Tropical Agriculture. Research stays in Ethiopia and Mexico sparked his interest in sustainable intensification of small-scale farming systems. He achieved a doctoral degree in Bioscience Engineering – Soil Science, also from K.U. Leuven.
Govaerts cut his teeth as cropping systems expert at CIMMYT, where he progressed from post-doctoral fellow to his current position. He received the Norman Borlaug Field Award in 2014 from the World Food Prize Foundation. Govaerts has co-authored over 90 peer-reviewed publications. He is a member of the Sustainable Development Solutions Network on Data and Statistics (TReNDS) for the Sustainable Development Goals and A.D. White Professor-at-Large at Cornell University.

In an article published in Nature Scientific Reports, a team of scientists led by wheat breeder Philomin Juliana from the International Wheat and Maize Improvement Center (CIMMYT) conducted a large genome-wide association study to look for genomic regions that could also be associated with resistance to wheat blast.
Juliana and fellow scientists found 36 significant markers on chromosome 2AS, 3BL, 4AL and 7BL that appeared to be consistently associated with blast resistance across different environments. Among these, 20 markers were found to be in the position of the 2NS translocation, a chromosomal segment transferred to wheat from a wild relative, Aegilops ventricosa, that has very strong and effective resistance to wheat blast.
The team also gained excellent insights into the blast resistance of the globally-distributed CIMMYT germplasm by genomic fingerprinting a panel over 4,000 wheat lines for the presence of the 2NS translocation, and found that it was present in 94.1% of lines from International Bread Wheat Screening Nurseries (IBWSNs) and 93.7% of lines from Semi-Arid Wheat Screening Nurseries (SAWSNs). Although it is reassuring that such a high percentage of CIMMYT wheat lines already have the 2NS translocation and implied blast resistance, finding other novel resistance genes will be instrumental in building widespread, global resilience to wheat blast outbreaks in the long-term.
The researchers used data collected over the last two years from CIMMYT’s IBWSNs and SAWSNs by collaborators at the Bangladesh Wheat and Maize Research Institute (BWMRI) and Bolivia’s Instituto Nacional de Innovación Agropecuaria y Forestal (INIAF).
Devastating fungal disease
Wheat blast, caused by the fungus Magnaporthe oryzae pathotype Triticum, was first identified in 1985 in South America, but has been seen in Bangladesh in recent years. The expansion of the disease is a great concern for regions of similar environmental conditions in South Asia, and other regions globally.
Although management of the disease using fungicide is possible, it is not completely effective for multiple reasons, including inefficiency during high disease pressure, resistance of the fungal populations to some classes of fungicides, and the affordability of fungicide to resource-poor farmers. Scientists see the development and deployment of wheat with genetic resistance to blast as the most sustainable and farmer-friendly approach to preventing devastating outbreaks around the world.
This work was made possible by the generous support of the Delivering Genetic Gains in Wheat (DGGW) project funded by the Bill & Melinda Gates Foundation, the U.K. Foreign, Commonwealth & Development Office (FCDO) and managed by Cornell University, the U.S. Agency for International Development’s Feed the Future initiative, the CGIAR Research Program on Wheat (WHEAT), the Indian Council of Agricultural Research (ICAR), The Swedish Research Council (Vetenskapsråd), and the Australian Centre for International Agricultural Research (ACIAR).
Farmers worldwide are increasingly adopting conservation agriculture. In the 2015/2016 season, conservation agriculture was practiced on about 180 mega hectares of cropland globally, 69% more than in the 2008/2009 season.
What are the benefits of this method of farming? How did it originate? In this episode, we answer common questions on conservation agriculture and talk to Simon Fonteyne, Research Platforms Coordinator with CIMMYT’s Integrated Development program and conservation agriculture expert.
On December 10, 1970, the former chair of the Nobel Committee, Aase Lionaes, called Norman Borlaug to receive the Nobel Peace Prize arguing, “He has given us a well-founded hope, an alternative of peace and of life — the Green Revolution.”
From that moment, Borlaug became known as “the man who saved one billion lives” from famine and as “the father of the Green Revolution.” Borlaug started a pivotal process in the 20th century, characterized by the development of high-yielding new wheat and maize varieties from the International Maize and Wheat Improvement Center (CIMMYT).
“Food is the moral right of all who are born into this world,” Borlaug said during his acceptance speech or Nobel Lecture almost 50 years ago. The scientist, credited for coining the phrase “You can’t build peace on empty stomachs,” became the world’s most acknowledged advocate of the right to food.
The Nobel Peace Center, the government of Mexico — through its Embassy in Oslo, Norway — and CIMMYT remembered Norman Borlaug’s legacy to commemorate the International Day of Peace on September 21. Established in 1981 by the United Nations General Assembly, this day calls to halt all forms of violence for 24 hours and to strengthen the ideals of peace, including Sustainable Development Goal number 2, ‘zero hunger.’
“Dr. Borlaug’s impact is an example of international cooperation for us to learn from and build the future,” said Ulises Canchola Gutiérrez, Mexico’s Ambassador to Norway, in the video Borlaug’s legacy: Agriculture for Peace #PeaceDay 2020.
According to the Nobel Peace Center, “Dr. Norman Borlaug’s work is one of the greatest achievements for humankind.” On a similar note, CIMMYT’s director general, Martin Kropff, noted that “Peace lies in the hands of those who cultivate the land. We can build peace through agriculture.”
CIMMYT carries on Borlaug’s legacy by implementing integrated strategic development projects that aim to transform food production units into sustainable, resilient and healthy agri-food systems. For that reason, CIMMYT issued a call to form an international coalition to tackle the current crisis and avert a new food crisis.
“Norman Borlaug led the charge in the war against hunger more than 50 years ago; let us learn from this experience, let us do it again together by listening to the current crisis and by developing a matching transformative answer to overcome today’s challenges and shortcomings,” said Bram Govaerts, director of CIMMYT’s Integrated Development program and representative for the Americas.
Scientists part of the Seed Production Technology for Africa (SPTA) and the Maize Lethal Necrosis Gene Editing projects are leveraging innovative technologies to transform seed production systems and speed up the delivery of disease resistance in elite new hybrids. This research is helping smallholder farmers in sub-Saharan Africa to access high-quality seed of new hybrids that were bred to perform under stressful low-input, drought-prone conditions, including farming regions impacted by maize lethal necrosis (MLN).
Fast delivery of MLN-tolerant varieties
The fight against maize lethal necrosis (MLN) has persisted for almost ten years now.
Collaborative efforts in diagnostics, management and systematic surveillance have limited its spread and confined the disease to the eastern Africa region. However, ongoing work is required to efficiently develop MLN-tolerant varieties for smallholders in endemic areas and prepare for the potential further movement of the disease.
“Maize lethal necrosis still exists. It has not been eradicated. Even though it has reduced in its prevalence and impact, it is still present and is a latent threat in Ethiopia, Kenya, Rwanda, Tanzania and Uganda, with potential to spread further,” said B.M. Prasanna, director of CIMMYT’s Global Maize Program and the CGIAR Research Program on Maize.
“That is why the work of the gene editing project is critical to rapidly change the genetic component of those susceptible parent lines of popular hybrids into MLN-tolerant versions,” said Prasanna. Scientists will edit the four parent lines of two popular hybrids, currently grown by farmers in Kenya and Uganda, which are susceptible to MLN. The edited MLN-tolerant lines will be used to make MLN-tolerant versions of these drought-tolerant hybrids.
Through gene editing technology, the time it takes to develop hybrids using traditional breeding methods will be cut in half. By 2025, the edited MLN-tolerant hybrids will be available for planting on approximately 40,000 hectares by about 20,000 Kenyan farmers.

Business as unusual
The unique seed production technology developed by Corteva Agriscience seeks to transform the seed production process in sub-Saharan Africa. This technology utilizes a dominant non-pollen producing maize gene to create female plants that are unable to produce pollen.
Seed companies that use seed production technology eliminate the need to detassel the female parent: a manual process through which tassels are removed from plants to prevent self-pollination and ensure that the intended male parent is the only source of pollen in the hybrid seed production field. Targeted small and medium-size seed companies could make significant savings to the cost of production if they were to eliminate manual detasseling. The method also helps to ensure the purity of the hybrid seed by removing the risk of unintentional self-pollination.
Hybrids produced using the seed production technology, characterized as 50 percent non-pollen producing (FNP), are unique since only half of the plants will produce pollen in the field. FNP hybrids re-allocate energy from the tassel and pollen production to grain formation, thus delivering an additional 200 kilograms per hectare yield advantage to the farmer. This represents a 10 percent productivity boost for farmers who will harvest approximately 2 tons per hectare, the average maize yield across sub-Saharan Africa. Farmers engaged in participatory research have demonstrated preference for FNP hybrids and associate the trait with higher yield and larger ear size.
As the first phase of Seed Production Technology for Africa (SPTA) wraps up, the collaborators are preparing for the next phase that will focus on commercializing, scaling up and increasing smallholders’ access to FNP. “This is among the unique partnerships funded by the foundation and I am hopeful that this incredible work will continue through the next phase,” said Gary Atlin, program officer at the Bill & Melinda Gates Foundation.

A win-win collaboration
Research and development work under the SPTA and the MLN Gene Editing projects has immensely benefited from the support of public and private partners. Seed companies and national institutions have contributed to improving access to and knowledge of these technologies as well as creating a crucial link with farmers. Ongoing engagement with regulatory agencies through the different stages of the projects ensures transparency and fosters understanding.
In order to assess the progress of these two initiatives, representatives from regulatory agencies, seed trade associations, seed companies, national agricultural institutions and funders came together for a virtual meeting that was hosted on July 29, 2020.
“KALRO embraces partnerships such as those that are delivering these two projects. That synergy helps us to resolve challenges faced by farmers and other actors in various agricultural value chains,” observed Felister Makini, deputy director general of Crops at KALRO.
As the primary technology provider, Corteva Agriscience provides the seed production technology system on a royalty-free basis and grants access to key gene editing technologies, which are the foundation for the two projects. Corteva Agriscience is also actively involved in project execution through collaborative scientific support.
“We have appreciated the opportunity to work with CIMMYT, KARLO, Agricultural Research Council (ARC) of South Africa and the Bill & Melinda Gates Foundation to bring some of the technologies and tools from Corteva to address significant challenges facing smallholder farmers in Africa. We could not have done this alone, it requires the partnerships that exist here to bring forth these solutions,” said Kevin Diehl, director of the Global Seed Regulatory Platform at Corteva Agriscience.
The International Maize and Wheat Improvement Center (CIMMYT) operates 11 hubs — nodes of innovation — in Mexico, supported by a portfolio of projects including MasAgro. These hubs are perfectly defined by the agro-ecological conditions of the territory in which they are located, and their main aim is innovation management focused on sustainable and resilient agri-food systems.
The Bajío Hub — which includes the central states of Guanajuato, Michoacán and Querétaro — is directed by Erick Ortiz Hernández, who through integrated management, seeks to improve farmers’ livelihoods working hand in hand with a large network of stakeholders, promoting and validating sustainable and scalable technologies.
Ortiz Hernández joined CIMMYT in 2010 as a collaborator in the state of Michoacán, where he trained and certified technicians, and managed the first modules and platforms of the MasAgro project. That experience allowed him to become the manager of the Yucatan Peninsula Hub, in southeastern Mexico, in 2015. After three years of serving in the state of Guanajuato, he has recently taken a management position at the Bajío Hub.
Growing up in a rural community of less than a thousand people in the state of Puebla, Ortiz Hernández was familiar with agriculture from a young age. However, he considers that his decision to pursue a career in agronomy was unplanned. It was when he got into the agronomy-engineering program at the Chapingo Autonomous University — one of the most prestigious institutions in agricultural studies in Mexico — that he realized how drawn he was to plant production, choosing it as his specialty.
“As a Chapingo student, you know that CIMMYT is one of the most relevant research institutions not only in Mexico, but internationally,” says Ortiz Hernández. “To be honest, when I graduated, I would never have imagined that I could be part of this great team.”
Tailored sustainability
Currently, he coordinates and manages the operation of different projects at the Bajío Hub, working with both the public and private sectors. All of them operate under the same objectives: to monitor and address activities in the value chain to improve production systems, produce more with less through conservation agriculture and precision farming practices, and achieve a successful association with the market.
One of these projects is Cultivando un México Mejor [Cultivating a Better Mexico], in partnership with Heineken Mexico. Through CIMMYT’s research and the implementation of improved management practices, experts explore the requirements for the sustainable management of water used in the daily cultivation process.
These actions are of utmost importance, since every year the region’s water tables are affected by the excessive use of water. Around 80% of the consumption of this natural resource is used for farming activities.
Ortiz Hernández explains that the production of 2.2 pounds of wheat in the region can require 1,500 liters of water on average. However, he and his team have shown that water consumption can be reduced by 30-50% by implementing practices that save water without decreasing yields and, ideally, with low production costs.

Linking for success
The Bajío Hub also manages MasAgro Guanajuato, a collaboration project between the government of state of Guanajuato and CIMMYT. Its aim is to support the technological improvement of conventional agri-food production, in order to implement actions of diagnosis, design, validation, demonstration and induction to the use of sustainable technological innovations.
One of the current situations faced by this program is that farmers in the area either broadcast or leave the fertilizer on the surface, resulting in an inefficient use. The technical team identified this problem and the possibility of mitigating it, by creating collaborative links with leading companies in the manufacture of agricultural machinery in the state, to design and produce a tool that meets this purpose.
“By working on a territorial innovation management approach, we get stakeholders to provide what is needed for farmers to access and adopt appropriate technology,” explains Ortiz Hernández. “What we expect from this type of project is not only to benefit the 500 or 1,000 farmers with whom we work directly, but to scale up and multiply those numbers generating an impact in the region through partnerships and alliances.”
Ortiz Hernández sees his management role as a strategic one, in which he has the flexibility to innovate by working with his team to generate efficient models, processes and tools. He can also propose and manage activities with different stakeholders in the region, so they can join in or align common objectives.
“There is no better moment than when farmers are harvesting and you see a smile on their faces due to the good results. When you know you contributed, even a little, you feel good and you come home happy,” says Ortiz Hernández.
One of his personal goals, and something he tries to incorporate into any project, is to create awareness of farmers’ major role in global food security. “We have to see farmers for what they really are: the people who ensure that food reaches our tables and who guarantee its quantity and quality. It is vital to recognize their daily efforts.”
It was the site where International Maize and Wheat Improvement Center (CIMMYT) scientist Norman Borlaug famously received news of his 1970 Nobel Peace Prize win. Now, Toluca station will become CIMMYT’s new testing site for rapid generation advancement and speed breeding in wheat – a method that accelerates generation advancement of crops and shortens the breeding cycle using tools like continuous lighting and temperature control.

The Toluca wheat experimental station is one of CIMMYT’s five experimental stations in Mexico, located in a picturesque town on the outskirts of Mexico’s fifth largest city, Toluca, about 60 kilometers southwest of Mexico City. The station was strategically chosen for its cool, humid conditions in summer. These conditions have made it an ideal location for studying wheat resistance to deadly diseases including yellow rust and Septoria tritici blotch.
Since its formal establishment in 1970, Toluca has played a key role in CIMMYT’s wheat breeding program. The site is also of significant historical importance due to its origins as a testing ground for Borlaug’s shuttle breeding concept in the 1940s, along with Ciudad Obregón in the Sonora state of northern Mexico. The breeding method allowed breeders to plant at two locations to advance generations and half the breeding cycle of crops.
Applying this unorthodox breeding method, Borlaug was able to advance wheat generations twice as fast as standard breeding programs. Planting in contrasting environments and day lengths — from the cool temperatures and high rainfall of Toluca to the desert heat of Ciudad Obregón — also allowed Borlaug and his colleagues to develop varieties that were more broadly adaptable to a variety of conditions. His shuttle breeding program was so successful that it provided the foundations of the Green Revolution.
Toluca was also the site where the first sexual propagation of the destructive plant pathogen Phytophtora infestans was reported. The deadly pathogen is best known for causing the potato late blight disease that triggered the Irish potato famine.

New life for the historic station
More than 50 years since its establishment, the station will once again host cutting-edge innovation in wheat research, as the testing ground for a new speed breeding program led by wheat scientists and breeders from Accelerating Genetic Gains in Maize and Wheat (AGG).
Funded by the Bill & Melinda Gates Foundation, the UK Department for International Development (DFID), the U.S. Agency for International Development (USAID) and the Foundation for Food and Agriculture Research (FFAR), AGG aims to accelerate the development and delivery of more productive, climate-resilient, gender-responsive, market-demanded, and nutritious maize and wheat varieties.
While most breeding programs typically take between 7-8 years before plants are ready for yield testing, shuttle breeding has allowed CIMMYT to cut the length of its breeding programs in half, to just 4 years to yield testing. Now, AGG wheat breeders are looking to shorten the breeding cycle further, through rapid generation advancement and speed breeding.

“The AGG team will use a low-cost operation, in-field screenhouse, spanning 2 hectares, to grow up to 4 generations of wheat per year and develop new germplasm ready for yield testing within just 2 years,” said Ravi Singh, CIMMYT distinguished scientist and head of wheat improvement. “This should not only save on cost but also help accelerate the genetic gain due to a significant reduction in time required to recycle best parents.”
Construction of the new rapid generation advancement and speed breeding facilities is made possible by support from the Bill and Melinda Gates Foundation and DFID through Delivering Genetic Gain in Wheat (DGGW), a 4-year project led by Cornell University, which ends this year. It is expected to be complete by September.

CIMMYT Global Wheat Program Director Hans Braun highlighted the importance of testing the new breeding scheme. “Before completely adopting the new breeding scheme, we need to learn, optimize and analyze the performance results to make necessary changes,” he said.
If all goes well, Toluca could once again be on the vanguard of wheat research in the near future.
“We plan to use the speed breeding facility for rapid integration of traits, such as multiple genes for resistance, to newly-released or soon to be released varieties and elite breeding lines,” said CIMMYT Wheat Breeder Suchismita Mondal, who will lead the work in these facilities. We are excited to initiate using the new facilities.”
With global agriculture in stasis and under threat from climate change, Latin America’s role to address these challenges through innovation and partnerships is crucial. This was the main takeaway from a 2020 
The World Food Prize Foundation is honoring the work of Rattan Lal, who dedicated his life to study the effect of soil health in food production and climate change mitigation. On October 15 he will receive the 2020 World Food Prize, considered the “Nobel Prize” of agriculture.
