Strengthening capacity and building national and regional partnerships in the seed sector

Written by Sarah McLaughlin on . Posted in Features.

Hybrid seeds exhibit a significant potential to boost on-farm productivity and attain food security. Still, the availability, affordability and accessibility of such quality seeds remain a challenge for farmers in South Asia. Primarily driven by the demand from the poultry industry, maize productivity in the region is increasing annually. Yet, the hybrid maize seed coverage is below 50% in most South Asian countries.

In continuation of its capacity-building initiatives, the International Maize and Wheat Improvement Center (CIMMYT) conducted an International Training Workshop on Quality Hybrid Maize Seed Production and Seed Business Management in South Asia on August 15-18, 2022, in Kathmandu, Nepal. The four-day hybrid training was jointly organized by Nepal’s Seed Quality Control Center, Nepal Agricultural Research Council (NARC), Seed Entrepreneurs’ Association of Nepal and CGIAR’s Seed Equal Initiative. Primarily, the event aimed at strengthening the capacity of seed stakeholders on the latest advances in quality hybrid maize seed production and establishing competitive hybrid seed business strategies.

Around 60 participants comprising of private seed company owners, national and international seed system specialists, maize breeders, crop inspectors, seed agronomists, marketers, policymakers and researchers working in hybrid seed production and marketing attended the training. Representatives were invited from Nepal, India, Bangladesh and Pakistan.

Principal trainer, John MacRobert, shared examples and knowledge in the principles of hybrid maize seed production and seed business. Former principal scientist of CIMMYT, MacRobert is currently the managing director of Mukushi Seeds Pvt Ltd in Zimbabwe and director of Quality Seed Pvt Ltd in South Africa. The training also involved group discussions and exercises on preparing a seed road map as well as developing profitable seed business plans. The participants used a seed business model canvas tool to chart their production plans, develop marketing strategies and diagnose profit. In 2018, MacRobert trained 15 private seed companies from Nepal and Pakistan on hybrid seed business mentorship course in Kathmandu. Since then, the participants brought in and shared rich practical experiences from their own businesses and regulatory organizations during this year’s program.

Joining MacRobert were 14 national and international experts from CIMMYT and other institutions, who delivered sessions related to hybrid maize breeding principles and techniques, seed quality control measures and regulations, and variety registration and licensing policies and procedures.

The forum offered an excellent learning opportunity for the national and international participants to exchange knowledge and experiences from seed specialists on developing competitive hybrid maize and seed production technologies that will bring cost-efficiency in production and maximize crop yields and business profits. It also served as a ground for establishing networks and collaborations. The mutual learnings will contribute to building national and regional partnerships in the seed sector.

Participants reflected on the learnings and benefits gained from the comprehensive course, which they would apply to improve maize productivity in their respective countries.

Muhammad Aslam, assistant professor from the University of Agriculture Faisalabad in Pakistan, acknowledged the opportunity provided to him and his university. He mentioned the support of CIMMYT in Pakistan in strengthening the local maize seed industry, where the market share of local seed companies is gradually increasing due to the elite germplasm support and capacity development efforts by CIMMYT. He added that the practical knowledge gained from the training will enhance the university students’ skills.

An ode to seeds

During the closing session of the training, Govinda Prasad Sharma, Secretary of the Ministry of Agriculture and Livestock, handed over diverse maize seeds to the NARC and seven private seed company partners of the Nepal Seed and Fertilizer (NSAF) project. CIMMYT acquired the elite maize parental lines and breeder seeds from its international maize breeding hubs in Mexico, Zimbabwe, Colombia and India. The seeds have the potential of yielding 6-7 metric tons per hectare for synthetics and more than 10 metric tons for hybrids–a significant increase from 3-5 metric tons of local seeds. More importantly, given the current climate challenges Nepali farmers are facing, these climate-resilient seeds reach maturity earlier than local varieties which reduces their exposure to drought. These seeds will also withstand Fall Armyworm infestations, a devastating pest threatening maize production in Nepal.

“Genetic materials that will not only enhance yield but diversify the gene pool of crops in Nepal is extremely important,” said Lynn Schneider, deputy director of the Economic Growth Office at United States Agency for International Development (USAID) Nepal. “Agriculture must combat climate change and malnutrition, which are critical for the South Asia region. So, I am really proud that we are working on these areas,” shared Schneider.

“Food security is a priority for the Government of Nepal,” explained Sharma. He mentioned maize as an essential commodity from the food and feed perspective for South Asia and plans to collaborate with the private sector and donor organizations to increase maize productivity in the country. “The event will definitely help in augmenting the activities and accelerate the pathway towards achieving food and feed security,” he added.

Moreover, a certificate of appreciation was presented to Nepal’s National Maize Research Program to recognize their effective collaboration in hybrid maize varietal promotion and source seed distribution. Similarly, three partner seed companies of the project were also recognized for the breakthrough in becoming the first recipients of the Government of Nepal’s research and development license to register and produce hybrid seeds on a commercial basis.

CIMMYT also launched an assessment report on Cereal Seeds Value Chain in Nepal that provides evidence-based recommendations for developing Nepal’s formal cereal seed sector, specifically maize and rice. The publication highlights the need for a well-performing seed system where high-quality seeds of a wide range of varieties and crops are produced and available in time and affordable to farmers.

Deepak Bhandari, executive director of NARC, also congratulated the authors and expressed the significance of formulating and implementing inclusive strategies to build a vibrant seed industry in Nepal. He also acknowledged the event organizers for conducting an exceptional international workshop on hybrid maize seeds for the public and private seed stakeholders.

The Excellence in Agronomy for Sustainable Intensification and Climate Change Adaptation Initiative launched in east and southern Africa on July 28-29 in Addis Ababa, Ethiopia, at a workshop with panel discussions and ideation sessions to determine key actions for the project.

The Initiative aims to deliver agronomic gain at scale for millions of smallholder farming households in prioritized farming systems, with emphasis on supporting women and young farmers, to demonstrate measurable impact on food and nutrition security, income, water use, soil health and climate resilience.

Co-creation of agricultural solutions with farmers is integral to the Initiative through the engagement of modern tools, digital technologies, and behavioral science.

At the workshop, participants created a shared understanding of the Initiative’s goals for the region, laid groundwork for in-country planning and implementation, and increased visibility of the Initiative. Attendees agreed on the need to reevaluate beyond the boundaries of traditional agronomic practices and microeconomic challenges, considering policies at national and regional levels.

Combining expertise from across CGIAR research centers, private sector actors and government agriculture departments, the Initiative takes a data-based approach to offer demand-driven solutions. This was of particular appeal to Eyasu Elias, deputy minister at Ethiopia’s Ministry of Agriculture, who described the approach as “truly commendable” in comparison to conventional supply-driven approaches.

Elias, who was represented by a delegate at the event, highlighted Ethiopia’s current three priorities: managing acid soils; managing Vertisols so they utilize their natural productive potentials; and adopting practices that mitigate the formation of salt-affected soils.

“Attaining food security will be a tremendous challenge under current conditions,” explained Elias’ representative. “More than ever, we need innovative agronomic solutions that enhance nutrient use efficiencies; we need solutions that can be crafted from locally available alternatives. Collaborations that allow co-creation, co-design and participatory technology generation along these lines are appreciated from our end.”

CIMMYT is prominent in global climate-food systems conversations, new study shows

Written by Mike Listman on . Posted in Publications.

Published in Nature Scientific Reports, a new study describes an innovative method to assess the reach and impacts of knowledge and partnerships created as part of the work of research-for-development organizations.

It uses text mining and the analysis of social networks and hyperlinks to draw inferences from publicly available digital sources, including institutional repositories, scientific databases, and social media.

“The method can uncover narratives, dynamics, and relationships that are hidden from traditional bibliometric analyses,” said Tek Sapkota, a cropping systems and climate change specialist at the International Maize and Wheat improvement Center (CIMMYT) and co-author or the study, which also involved the University of Coimbra, Portugal, and the University of Molise, Italy.

“Nearly 90 percent of CIMMYT’s research is related to climate change and its impact on food systems and vice-versa, so we assessed that to illustrate our new, web-based analytical framework. This novel approach can help research-for-development organizations to leverage online data and measure their impact.”

The eastern Indo-Gangetic plains (EIGP) have a higher density of rural poverty and food insecurity than any other region. The region’s intensive rice-wheat cropping system has large yield gaps, which are far higher than anywhere in South Asia, coupled with an increasing environmental footprint due to conventional agricultural practices.

To sustainably enhance cereal crop productivity and improve smallholder farmers’ livelihoods in Bangladesh, India, and Nepal, the Cereal Systems Initiative for South Asia (CSISA), a science-driven and impacts-oriented regional project led by the International Maize and Wheat Improvement Center (CIMMYT), was launched in 2009.

Over the years, working with public and private partners, CSISA has helped smallholder farmers increase their yield and supported widespread adoption of resource-conserving and climate-resilient farming technologies and practices. Through three phases from 2009 to 2021, the project impacted nearly 8.5 million farmers (mainly smallholders) through its research and agri-system innovation interventions.

A new three-and-a-half-year commitment in India by the Bill & Melinda Gates Foundation reinforces the project’s importance and value in reducing food insecurity and improving overall agri-food systems in the region.

“CSISA, over more than a decade, has built up a strong multi-institutional, interactive, and participatory team at all levels in the region,” said Peter Craufurd, project leader of CSISA in India. “It has developed competencies and skills that include problem-solving agronomy research, cross-cutting tools and analytics, policy reform, and capacity development to strengthen cropping systems for smallholder farmers in the region.”

The overarching objective of CSISA 4.0 is to transform how agronomic research and extension are implemented and embedded in decision-making and policy processes, primarily in India, where CSISA has the most experience and influence. Phase 4.0 will leverage the investments made in India in the third phase and focus on institutionalizing interventions through partnerships with the national and state agricultural systems, including on-ground strategic partnerships with civil society and the private sectors. According to Craufurd, Phase 4.0 will further strengthen the pathways established and scale the impact, particularly the institutional research and development capacity and strategic partnerships thus far established in India, through its seven focussed work areas, including gender empowerment.

“We are confident of our strong partnership with the national systems led by the Indian Council of Agricultural Research (ICAR) to support Indian farmers with improved yield and productivity,” said R.K. Malik, CSISA India coordinator. “Over the last decade, CSISA has built a strong track record for agronomy at scale that can help transform agri-research delivery systems in the region. There is also the opportunity to make CSISA outputs and products portable or useable for other stakeholders addressing food insecurity in the region in the future.”

Implemented jointly with CGIAR partners the International Rice Research Institute (IRRI) and the International Food Policy Research Institute (IFPRI), the initiative has been a successful regional approach to impactful agronomy programming. The CSISA team hopes to continue supporting the smallholder farmers in the region to optimize yield and contribute to the region’s food security.

Cereal seed systems

Written by Sarah McLaughlin on . Posted in Explainers.

For certified seed to reach a farmer’s field for cultivation, it passes through many hands – international and national breeding programs, government regulatory agencies, private seed companies, and retailers or agrodealers. These organizations each play an important role in the design, testing, production and distribution of improved maize and wheat varieties.

Together, these processes, actors, and the relationships between them form a seed system, which incorporates the production, conservation, exchange, and use of propagation materials for crops. As defined by the CGIAR Community of Excellence for Seed Systems Development (COE), seed systems are complex, involving arrangements between public and private sectors, layers of regulation, and years of research and development, and are specific to each crop, country, agroecological environment and market context.

The International Maize and Wheat Improvement Center (CIMMYT) has extensively researched and worked with the facets and actors of cereal seed systems in Latin America, Asia and Africa, specifically in relation to cereal crops, and with maize and wheat in particular.

The role of CIMMYT scientists in supply and demand

Breeding teams use traditional and advanced techniques to identify improved maize and wheat breeding lines according to the desired traits determined by farmers and consumer markets. In addition to higher grain yields, other preferred traits include more and larger grains or fruit, resistance to pests and diseases, tolerance to environment pressures (such as drought or poor soils), better nutritional quality, or flavor and ease of processing.

These lines are used for further breeding, testing, seed multiplication by public and private sector partners. Others engage in varietal testing on farmers’ fields and support seed companies in production.

To foster smallholder farmers’ access to these improved varieties, CIMMYT implements a seed systems strategy divided into supply side development, concerning breeding and seed production, and demand side development, covering issues related to variety distribution and uptake. On the supply side, CIMMYT scientists’ work is carried out in three phases:

  • Product development phase: Breeders advance through CIMMYT’s breeding funnel (pipeline) the most promising materials from one improvement stage to the next. The best candidates are first tested in field trials at research stations and then in farmers’ fields. Afterwards, CIMMYT organizes field days to showcase the best performing materials to public and private sector partners.
  • Product allocation phase: Local partners request new CIMMYT products and sign licensing agreements that protect the new seed from private ownership claims and help accelerate marketing and distribution in target regions at affordable prices.
  • Release and commercialization phase: Farmers can obtain and benefit from seed of improved maize and wheat once national authorities register and release varieties that excel in national performance trials and public and private sector partners begin seed production and marketing or distribution.

On the demand side, CIMMYT scientists work to support seed systems development though its work on:

  • Farmer preferences and demand for varieties: Scientists look to understand current and future preferences and needs for varieties. This involves the use of innovative tools, such as product concept testing, on-farm testing and ranking, and participatory varietal evaluation.
  • Seed industry development: Small and medium sized seed businesses, as well as agrodealers, play a critical role in the distribution of seed. Our work looks to understand entry points for support to the seed industry for advancing faster uptake of new varieties by farmers.
  • Consumer demand for grain: The preferences of consumers and agroindustry for grain and grain-based foods provide an important source of demand for new varieties. CIMMYT scientists engage with consumers and agroindustry for innovation in food product design and testing consumer acceptance. Insights gains are reported back to breeding and seed production teams for design of future cereal varieties.

Gender-sensitive seed systems

A team of social scientists at CIMMYT with expertise in economics, gender and marketing works to understand the needs and preferences of farmers, consumers, and the agroindustry for new varieties. They develop retail strategies, such as targeted marketing, in-store seed assessment support and price incentives, promote the adoption of better policies in support of seed companies and seed markets.

CIMMYT explores mechanisms to help seed companies adapt their products to women’s preferences. Research shows that beyond yield potential, women seek different characteristics in seeds than men. For example, women are more inclined to favor a variety with a longer grain shelf life. Similarly, when women engage in participatory variety selections, they tend to make more objective evaluations of varieties than men.

Our experts advance strategies to promote inclusive and effective delivery systems, helping both female and male farmers obtain the seed that works best for their specific needs. This ongoing model gives CIMMYT feedback from farmers and public and private sector partners, which informs subsequent breeding research.

Why are cereal seed systems important?

CIMMYT contributes to new improved seeds getting to farmers, consumers and agroindustry, which ultimately leads to lasting positive impacts in terms of food security and economic development.

Cereals such as maize and wheat play a critical role in global food security. Increasing their productivity in the Global South remains a key developmental priority. Smallholders face increasing pressure to sustain and increase their yields in the face of three main issues: climate change, which increases the frequency of severe drought, floods, and pest and disease outbreaks; rapidly rising costs of inputs, such as land, labor, fertilizer; and unfavorable marketing conditions for their grain.

As a critical entry point for improved agricultural technology, seed systems are in urgent need of improvement and modernization. Since the onset of the Green Revolution in the 1960s, the discovery, development, and delivery of improved seed for smallholder farmers has remained an essential part of global and local initiatives to increase smallholder productivity.

What does a sustainable, inclusive, and productive seed system look like?

For the future, there are serious challenges for expanding and deepening the impact from investments in breeding. Market intelligence systems are urgently needed to support breeding teams in future product design and evidence-based prioritization. Innovation is needed in terms of how actors within the systems inform and support farmers to experiment with new seeds.

CIMMYT is working with CGIAR partners to implement a new, 10-year strategy. Effective seed systems achieve the widespread adoption of varieties that capture the gains from crop improvement and connect actors along the value chain so that all can benefit from a productive crop, from seedbank to soil. In close collaboration with national agricultural research systems (NARS), CGIAR has had historic success introducing improved cultivars to smallholder producers of staple crops, with high return on investment. However, there is still some standing criticism that large, public breeding programs take a technologically-biased and supply-pushed approach to agricultural innovation.

Cereal crop breeding programs can become more demand-oriented by employing more market segmentation strategies – breaking down target client markets into smaller, more geographically and demographically specific groups – and developing a more accessible description and profile of its products. Using similar approaches, CGIAR is likely to expand demand-oriented programs in genetic innovation and seed systems development in the new phase of operations.

The negative impacts of climate shocks have undermined the food security of millions of people in Ethiopia, where predominantly rain-fed agriculture and cereals comprise 82% of the crop area and are particularly susceptible to extreme climate events like drought or flooding. Predictions that can account for potential climate events can facilitate efforts of governmental agencies to proactively engage in climate mitigation efforts.

Led by the International Center for Maize and Wheat Improvement (CIMMYT), the Accelerating Impact of CGIAR Climate Research for Africa (AICCRA) project conducted a five-day training workshop in Adama, Ethiopia for 12 data experts from 23-27 December 2021 on the CCAFS Regional Agricultural Forecasting Toolbox (CRAFT) Tool.

The five-day training workshop exposed select national experts involved in data collection and analysis of crop performance to the CRAFT tool, which is expected to improve accuracy, efficiency, and speed of forecasts.

The participants of the training were experts from the Ministry of Agriculture (MoA), National Meteorology Agency (NMA), and Ethiopian Disaster Risk Management Commission (EDRMC).

CRAFT has been developed in collaboration with CIMMYT, the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), and the University of Florida through the Capacitating African Smallholders with Climate Advisories and Insurance Development (CASCAID-II) program. CRAFT is a flexible and adaptable software platform, relying on a crop engine to run pre-installed crop models and on the Climate Predictability Tool (CPT) to utilize seasonal climate predictions to produce crop yield forecasts. The tool has been calibrated, evaluated, and tested under Ethiopian ecological conditions.

In the opening of the training workshop, Esayas Lemma, Director of the Crop Development Directorate at the MoA, emphasized institutions must be equipped with the necessary analytical and decision support tools to enable decision makers to make critical decisions at the right time due to increasing challenges to food security. He added the training organized by CIMMYT through the AICCRA-Ethiopia project was timely and important for enhancing the capacity of the experts drawn from the three institutions and building national capacity in using modern decision support tools.

Kindie Tesfaye, senior scientist at CIMMYT, stated the training was organized to help experts in national institutions in applying decision support tools to equip decision makers with information to help them minimize costs, save lives, and enhance long-term climate risk management and policy options in Ethiopia. “We hope to bring this technology to other countries following this roll-out in Ethiopia,” Tesfaye said.

“The training is an eye-opener for me, and this is the type of tool that we have been looking for,” said Mss. Berktawit, a trainee from EDRMC.

“The CRAFT tool has several applications in the MoA, and we are lucky to have this training. With some additional training, we at the ministry should be able to use it to support our crop monitoring and early warning works,” said Mr. Zewdu, a trainee from the MoA.

A follow up training session will be organized to certify participants as they continue working with CRAFT. “Feedback from these users will be vital to optimize inputs for CRAFT and to develop an intuitive user interface,” Tesfaye said.

In Ethiopia, local challenges inform national action for climate-smart agriculture

In some of Ethiopia’s most vulnerable communities, climate change is having a disastrous effect on agriculture, a critical sector to the livelihood of millions. Droughts, floods, pests, and disease outbreaks are key challenges farmers face in the age of the climate crisis. These climate-related threats have already contributed to reducing agricultural productivity and food insecurity.

In order to minimize agricultural risks from the above challenges and maximize farmers’ resilience, there is a critical need to introduce the technologies, innovations, and practices that underpin ‘climate-smart agriculture. For instance, cascading knowledge on agricultural risk management and promoting conservation agriculture may prove to be sustainable practices that address the limiting factors of food security. This, however, cannot be done in a ‘one-size-fits-all’ approach. In Ethiopia, we’ve seen how climate-smart agriculture (CSA) not only needs to be localized – so it is effective in different environments – it also needs to be inclusive, meeting the needs of women and youth in various communities.

CSA is critical to making Ethiopian farmers and their communities more resilient in the face of climate change. Awareness-raising campaigns and consultations fit an important role in engaging scientists, practitioners, and beneficiaries to understand and implement area-specific climate adaptation mechanisms through CSA-based input. A current challenge is that climate-smart interventions in Ethiopia are limited because of a lack of awareness of the necessary skill set to implement and manage those technologies properly. After all, it is wise to remember that CSA is a knowledge-intensive exercise. For instance, let us look at the Ethiopian highlands, which constitute a substantial amount of the country’s farming population. In the extreme highlands of Ethiopia – generally dubbed as Wurch or mountain zone above 3800m elevation above sea level – CSA implementation is even scarce due to climatic and socio-economic conditions. In fact, those parts of the highlands are often referred to as the “forgotten agroecology” and agricultural research institutions – both in Ethiopia and beyond – must develop and package climate-smart interventions tailored for regions that have these agroecological characteristics.

Despite some practical challenges, it is also wise to note that there are successful cases of CSA implementation and addition across the various parts of the country. This is recognized for the literature review to document CSA experiences in the country and develop a detailed ‘CSA compendium’. These experiences can promote public engagement informed and inspired by the practical experience of climate-smart interventions, both from sites that have similar agroecological characteristics – as well as different – so that farmers and communities can learn from the successes and failures of other ventures. This public engagement should be underpinned by business and financing models that work for resource-poor farmers, so they can access or invest in making their agriculture more climate-smart.

Knowing what works where will be essential to develop strategies that can facilitate targeting and scaling CSA approaches. Developing a CSA compendium, a collection of concise but detailed information on CSA practices can be an entry point to achieve this – which also requires efforts from various experts and collaboration among institutions in the country and beyond.

In line with this understanding, a recent workshop in Ethiopia brought together researchers from the Ethiopia Institute of Agricultural Research (EIAR) and the Ministry of Agriculture, the Regional Bureau of Agriculture, alongside partners from regional agricultural research institutes, Universities, and CGIAR centers.

It aimed to raise awareness among partners on the kinds of climate-smart packages of agricultural technologies and practices that are socially inclusive and responsive to the needs of young people while also being feasible from a socio-economic standpoint and ready to be expanded and delivered on a bigger scale. Key presentations were made about what CSA is and what it is not. In addition, the type and description of indicators used to identify CSA practices that are economically feasible, socially acceptable, and gender-responsive were discussed in-depth. As part of this exercise, experts identified more than 20 potential climate-smart agriculture interventions tested, validated, and implemented effectively in different parts of the country.

Some of the key presentations and discussions at the workshop revealed critical lessons for implementing CSA:

  • Climate-smart agriculture is not a set of practices that can be universally applied but rather an approach that involves different elements embedded in local contexts.
  • Climate-smart agriculture relates to actions both on farms and beyond the farm, incorporating technologies, policies, institutions, and investment.”
  • Climate-smart agriculture is also a continuous process, though we should focus on the big picture and avoid trivial debates about whether CSA is a practice, technology, or an option.
  • Due consideration should be given to gender sensitiveness and social inclusiveness as a criterion in identifying compelling innovations.
  • Better indicators should be developed in measuring how climate-smart agriculture is adopted.

The workshop was the first of a series planned to raise awareness of different approaches to climate-smart agriculture while aligning Ethiopian institutions behind common understandings of how climate-smart agriculture can be delivered at both a local and national level.

In closing this first workshop, Ermias Abate, Deputy Director-General of the Amhara Region Agricultural Research Institute, stated, “Agriculture wouldn’t move an inch forward if we continued with business as usual and hence the need to be smart to face the new realities of agriculture under climate change.”

The Accelerating Impacts of CGIAR Climate Research in Africa (AICCRA) workshop was held between December 24 and 25, 2021, in Bahir Dar, Ethiopia, and was organized jointly by:

  • The Alliance of Bioversity International and the International Center for Tropical Agriculture (CIAT)
  • CGIAR Program on Climate Change Agriculture and Food Security (CCAFS)

Biological nitrogen fixation and prospects for ecological intensification in cereal-based cropping systems

Written by Sarah McLaughlin on . Posted in Publications.

Among the inputs needed for a healthy soil, nitrogen is unique because it originates from the atmosphere. How it moves from the air to the ground is governed in part by a process called biological nitrogen fixation (BNF), which is catalyzed by specific types of bacteria.

Nitrogen supply is frequently the second most limiting factor after water availability constraining crop growth and so there is great farmer demand for accessible sources of nitrogen, such as synthetic nitrogen in fertilizer. This increasing demand has continued as new cereal varieties with higher genetic yield potential are being released in efforts to feed the world’s growing population.

Currently, the primary source for nitrogen is synthetic, delivered through fertilizers. Synthetic nitrogen revolutionized cereal crop (e.g., wheat, maize, and rice) production by enhancing growth and grain yield as it eliminated the need to specifically allocate land for soil fertility rejuvenation during crop rotation. However, synthetic nitrogen is not very efficient, often causing excess application, which leads to deleterious forms, including ammonia, nitrate, and nitrogen oxides escaping into the surrounding ecosystem, resulting in a myriad of negative impacts on the environment and human health. Nitrogen loss from fertilizer is responsible for a nearly 20% increase in atmospheric nitrous oxide since the industrial revolution. Notably, more nitrogen from human activities, including agriculture, has been released to the environment than carbon dioxide during recent decades, leading climate scientists to consider the possibility that nitrogen might replace carbon as a prime driver of climate change.

New research co-authored by International Maize and Wheat Improvement Center (CIMMYT) scientists, published in Field Crops Research, posits that facilitating natural methods of gathering useable nitrogen in BNF can reduce the amount of synthetic nitrogen being used in global agriculture.

As agricultural systems become more intensive regarding inputs and outputs, synthetic nitrogen has become increasingly crucial, but there are still extensive areas in the world that cannot achieve food and nutrition security because of a lack of nitrogen.

“This, together with increasing and changing dietary demands, shows that the future demand for nitrogen will substantially grow to meet the anticipated population of 9.7 billion people by the middle of the century,” said J.K. Ladha, adjunct professor in the Department of Plant Sciences at University of California, Davis, and lead author of the study.

Before the synthetic nitrogen, the primary source of agricultural nitrogen was gathered through BNF as bacteria living underground that convert atmospheric nitrogen into nitrogen that can be utilized by crops. Therefore, legumes are often employed as a cover crop in rotating fields to replenish nitrogen stocks; their root systems are hospitable for these nitrogen producing bacteria to thrive.

“There are ways in which BNF could be a core component of efforts to build more sustainable and regenerative agroecosystems to meet nitrogen demand with lower environmental footprints,” said Timothy Krupnik, Senior System Agronomist at CIMMYT in Dhaka, Bangladesh.

Plant scientists have often hypothesized that the ultimate solution for solving the ever-growing nitrogen supply challenge is to confer cereals like wheat, maize, rice, with their own capacity for BNF. Recent breakthroughs in the genomics of BNF, as well as improvements in the understanding how legumes and nitrogen bacteria interact, have opened new avenues to tackle this problem much more systematically.

“Enabling cereal crops to capture their own nitrogen is a long-standing goal of plant biologists and is referred to as the holy grail of BNF research,” said P.M. Reddy, Senior Fellow at The Energy Research Institute, New Delhi. “The theory is that if cereal crops can assemble their own BNF system, the crop’s internal nitrogen supply and demand can be tightly regulated and synchronized.”

The study examined four methods currently being employed to establish systems within cereal crops to capture and use their own nitrogen, each with their advantages and limitations. One promising method involves identifying critical plant genes that perceive and transmit nitrogen-inducing signals in legumes. Integrating these signal genes into cereal crops might allow them to construct their own systems for BNF.

“Our research highlights how BNF will need to be a core component of efforts to build more sustainable agroecosystems,” said Mark Peoples, Honorary Fellow at The Commonwealth Scientific and Industrial Research Organisation (CSIRO), Canberra, Australia. “To be both productive and sustainable, future cereal cropping systems will need to better incorporate and leverage natural processes like BNF to mitigate the corrosive environmental effects of excess nitrogen leaking into our ecosystems.”

Besides the efforts to bring BNF to cereals, there are basic agronomic management tools that can shift focus from synthetic to BNF nitrogen.

“Encouraging more frequent use of legumes in crop rotation will increase diversification and the flow of key ecosystem services, and would also assist the long-term sustainability of cereal-based farming systems­,” said Krupnik.

Mexican farming can transition to be more resilient with technology

Written by Sarah McLaughlin on . Posted in News.

In Mexico and around much of the world, the cost of food fell sharply last month but it remains dangerously close to the all-time highs posted earlier this year, according to an agency of the United Nations.

New data from the Food Price Index of the Food and Agricultural Organization provide even more proof that if we’re to build a resilient system of agriculture that keeps food abundant and affordable, farmers like me need access to the best, forward-facing and science-based technologies—and not the backward-looking restrictive measures that many governments are trying to force upon food producers.

That’s especially true here in Mexico, where public officials are promoting dangerous agriculture policies that will damage yield potential of Mexico’s farmers and add to our country’s current food inflation. Paradoxically, the world’s leading agricultural research center for wheat and maize has issued a new call for “long-term agri-food system resilience.”

The International Wheat and Maize Improvement Center, also known as CIMMYT and headquartered just outside Mexico City, is an amazing resource for farmers everywhere. My family has participated in its work for decades, going back to when Norman Borlaug, the father of the Green Revolution, was starting to make big progress on wheat yields.

In July, a team of CIMMYT scientists published their strategy for dealing with soaring food prices. They focused mainly on wheat, which was subjected to so much stress because of the Russian invasion of Ukraine, but their general recommendations apply to every commodity.

Their short-term advice involves boosting production and partially replacing wheat flour with other low-cost cereals to off-set high wheat prices. In the middle and long terms, CIMMYT calls for more resilience in our food systems by genetically improving seeds and controlling pests. Significantly, the authors urge “building capacity to promote extensive pest and pathogen monitoring.”

This is important advice because pests, weeds, and disease are three of the biggest threats to food production pretty much everywhere. If we’re going to develop a “long-term agri-food system resilience” that involves everything from the climate-change mitigation and gender equity that CIMMYT also advocates, it must start by helping farmers like me defend our crops from their most basic but permanently evolving threats.

And that means giving us access to science-based technology. We need the best seeds, the best machines, and the best crop management techniques. We also need the best crop protection so that what we plant can meet its full potential.

Rather than limiting the options of farmers we should seek to expand them. This in fact is the great legacy of CIMMYT. Through sound science and creative innovation, it has given farmers more tools than ever before.

On my farm, we already fight pests, weeds, and disease through traditional practices like crop rotation. Yet this age-old practice is no longer enough. In this era of sustainability and conservation, we especially need advanced crop protection, which can function as a “virtual plow” that strengthens our soil as it locks in moisture, kidnaps carbon, enhances biodiversity, improves root systems, and reduces erosion.

In the years ahead, we’d like to explore additional crop-protection technologies, such as drone applications which would allow us to work with more precision and less dependence on fossil fuels.

As we think about the future, and as farmers everywhere try to grow more food on less land, we should embrace technology as a solution rather than fear it as a problem.

We have so many real problems with war, inflation, access to fuel and fertilizer, market turmoil, and climate change that we don’t need to restrict ourselves by hesitating in the application of new technologies, especially when they have been demonstrated to be safe. (If we trick ourselves into banning these options, farmers will pay a steep price as they struggle to grow food and consumers will bear the cost of it whenever they eat.)  All technological options should remain on the table.

Although food prices fell by 8.6 percent between June and July, they are more than 13 percent higher than they were at this time last year, according to the FAO’s Food Price Index.

This may be a silver lining amid dark clouds, but the forecast is unpredictable: “The decline in food commodity prices from very high levels is welcome,” said FAO chief economist Maximo Torero, who also warned that “many uncertainties remain” and they “pose serious strains for global food security.”

Agriculture must become more resilient, as CIMMYT pleads.

And farmers like me need the support of policy makers and the general public as we struggle to grow the food everyone needs.

The potential of conservation agriculture in increasing yield and tackling climate change

Written by Celine Lim on . Posted in Publications.

A multitude of research on the benefits of conservation agriculture in South Asia has predominantly focused on favorable environments where farmers have reliable access to energy supporting irrigation and inputs.

In this new publication, scientists from the International Maize and Wheat Improvement Center (CIMMYT) explore the performance of conservation agriculture in under-developed coastal environments in southern coastal Bangladesh over a period of three consecutive years, including under rainfed conditions and/or with limited application of irrigation.

Responding to the identified research gap, this research tests the hypothesis that seasonally alternating tillage (SAT) practices that alternate between strip-tillage in the winter season for maize and conventional tillage (CT) prior to rice can reduce energy use, increase energy productivity, and reduce yield-scaled emissions while increasing or maintaining yield and profit, even under these challenging conditions.

Working with 35 farmers who managed experiments in partially irrigated and rainfed environments in southern coastal Bangladesh, researchers teamed up with farming communities to compare the full suite of conservation agriculture to SAT practices against CT and farmer’s own practices.

The research found that in these coastal environments, both conservation agriculture and SAT practices have the potential to increase cereal yields and energy productivity while reducing yield-scaled emissions, thereby enabling farmers even in challenging coastal environments to produce more while reducing energy use and mitigating greenhouse gas emissions.

However, in consideration of farmers’ aversion to the elimination of tillage in rice, the research suggests that adaptations in CA practices and seasonal tillage prior to rice may be a more practical fit for rice-maize systems managed by smallholders reluctant to eliminate tillage for rice in coastal Bangladesh.

This research gives implications for future research and development efforts to take into consideration farmers’ preferences or the trade-offs resulting from significant change to conservation agriculture management in otherwise fully tilled systems. It is also vital to integrate development efforts that focus not only on agronomic management, but also on building supportive value chains to improve availability and affordability of the inputs and farm machinery required to successfully establish crops with such practices.

The power of data in improving conditions for female farmers

Written by Sarah McLaughlin on . Posted in Publications.

Despite women’s essential role in agrifood systems, their contribution can be overlooked, with resources instead targeted towards their male counterparts.

However, advancements in technology now allow scientists to generate rich datasets that can aid analysis of the situational factors impacting women farmers’ participation in extension training services.

These developments have enabled scientists from the International Maize and Wheat Improvement Center (CIMMYT), Michigan State University, and Agricultural Advisory Society, a local NGO, to understand barriers to access and recommend improvements that will benefit women in Bangladesh.

Using a large dataset of 131,073 farmers in Bangladesh, researchers worked to identify ways to tackle gender exclusion in extension training. Scientists used machine learning to understand preferences according to gender and applied optimization theory and identified actionable ways to increase the number of farmers participating in video- and multi-media mediated trainings, while simultaneously improving gender inclusivity in public training events.

The study discovered strong gender specific considerations, such as the training session’s day of the week and time and the gender of the trainer, which prevented women from or encouraged them to take part in educational events.

It also demonstrates the potential for big data to transform our understanding of unstructured and semi-structured data into statistically verifiable insights that can genuinely impact farmer’s lives. Optimizing women’s involvement in agrifood systems can additionally play an important part in efforts to enhance farm productivity, gender and social inclusion, and nutrition in Bangladesh and beyond.

Conservation agriculture practices revive saline and sodic soils

Written by Sarah McLaughlin on . Posted in Publications.

In arid and semi-arid regions, soil salinity and sodicity pose challenges to global food security and environmental sustainability. Globally, around 932 million hectares are affected by salinization and alkalinization. Due to growing populations, anthropogenic activities and climate change, the prominence of salt stress in soil is rising both in irrigated and dryland systems.

Scientists from the International Maize and Wheat Improvement Center (CIMMYT) and the Indian Council of Agricultural Research (ICAR) employed long-term conservation agriculture practices in different agri-food systems to determine the reclamation potential of sodic soil after continuous cultivation for nine years, with the experiment’s results now published.

Using different conservation agriculture techniques on areas cultivating combinations of maize, wheat, rice and mungbean, the study used soil samples to identify declines in salinity and sodicity after four and nine years of harvesting.

Evidence demonstrates that this approach is a viable route for reducing soil sodicity and improving soil carbon pools. The research also shows that the conservation agriculture-based rice-wheat-mungbean system had more reclamation potential than other studied systems, and therefore could improve soil organic carbon and increase productive crop cultivation.
