research: Sustainable agrifood systems

50 years building peace through agriculture

Written by Ricardo Curiel on September 22, 2020. Posted in Videos.

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 20^th 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.

CIMMYT and IITA collaborate to increase adoption of conservation agriculture in southern Africa

Written by Rodrigo Ordóñez on September 21, 2020. Posted in Press releases.

The International Institute of Tropical Agriculture (IITA) and the International Maize and Wheat Improvement Center (CIMMYT) recently launched a project that aims to research the drivers and barriers to adoption of conservation agriculture in southern Africa, and to develop strategies for achieving adoption and impact at scale.

The project, Understanding and Enhancing Adoption of Conservation Agriculture in Smallholder Farming Systems of Southern Africa (ACASA), will apply social and scaling science to understand the biophysical, socioeconomic, institutional, and policy drivers and barriers to the adoption of conservation agriculture technologies and practices.

The ACASA project is supported by the Norwegian Agency for Development Cooperation (Norad) and will be implemented in Malawi, Zambia, and Zimbabwe in collaboration with partners and farmers in the region.

The project was officially launched online on September 16, 2020. Zambia’s Minister of Agriculture, Michael Katambo, noted that it is a timely intervention, as the livelihoods and food security of smallholder farmers in southern Africa are increasingly being threatened by climate change and variability, which have led to a steady decline in the production of food staples and an increase in the number of food and nutrition-insecure people.

“It is now clear that current productivity and production levels cannot be expected to meet our requirements for food and nutrition security,” Katambo said in a speech read on his behalf by Moses Mwale, Director of the Department of Agriculture. “Conservation agriculture has a proven potential to increase and stabilize crop yields, and to support sustainable and resilient production systems and rural livelihoods.”

Proven benefits

Conservation agriculture — a farming system that promotes minimum soil disturbance, permanent soil cover and diversification of plant species — can efficiently increase agricultural productivity while reducing land degradation and improving soil health for more productive, profitable, and sustainable farming.

Substantial on-farm evidence has been generated on the agronomic and economic benefits of conservation agriculture, first introduced in the 1970s in South Africa. Consequently, donors and governments have made a lot of investments to promote and scale conservation agriculture technologies and practices among smallholder farmers in the region. Despite all these efforts, however, the adoption rate among smallholder farmers remains low.

“We should not let the low adoption of conservation agriculture discourage us. Let us use this opportunity to reflect and identify the missing link and come up with more sustainable solutions to the problem,” said the IITA Director for Southern Africa, David Chikoye.

“Although adoption of improved practices by most resource-poor farmers is primarily determined by the potential immediate benefits on crop yields, profits, risk, and livelihoods, there are a number of biophysical, socioeconomic, institutional, and policy factors that promote or hinder adoption of conservation agriculture. The project, therefore, aims to identify the adoption drivers and barriers, and to develop pathways and strategies for inclusive scaling of conservation agriculture practices,” said Arega Alene, Agricultural Economist at IITA and leader of the ACASA project.

Christian Thierfelder, Principal Cropping Systems Agronomist at CIMMYT, highlighted some of the bottlenecks for conservation agriculture adoption, noting they were linked more to socioeconomic and cultural factors rather than biophysical. “Conservation agriculture is a viable and proven climate-smart farming system. Future research efforts should go towards understanding farmers’ decision-making and behavioral change, as well as profitability,” Thierfelder said.

Other key partners include the Food and Agriculture Organization of the United Nations (FAO), the African Conservation Tillage Network (ACT) and Centre for Coordination of Agricultural Research and Development for Southern Africa (CCARDESA).

The project launch was attended by policymakers, donors, members of national and regional conservation agriculture taskforces, national and international research institutions, universities, international development institutions, private seed companies, non-governmental organizations, and farmer organizations.

Retrospective quantitative genetic analysis and genomic prediction of global wheat yields

Written by Marcia MacNeil on September 17, 2020. Posted in Publications.

The process for breeding for grain yield in bread wheat at the International Maize and Wheat Improvement Center (CIMMYT) involves three-stage testing at an experimental station in the desert environment of Ciudad Obregón, in Mexico’s Yaqui Valley. Because the conditions in Obregón are extremely favorable, CIMMYT wheat breeders are able to replicate growing environments all over the world and test the yield potential and climate-resilience of wheat varieties for every major global wheat growing area. These replicated test areas in Obregón are known as selection environments (SEs).

This process has its roots in the innovative work of wheat breeder and Nobel Prize winner Norman Borlaug, more than 50 years ago. Wheat scientists at CIMMYT, led by wheat breeder Philomin Juliana, wanted to see if it remained effective.

The scientists conducted a large quantitative genetics study comparing the grain yield performance of lines in the Obregón SEs with that of lines in target growing sites throughout the world. They based their comparison on data from two major wheat trials: the South Asia Bread Wheat Genomic Prediction Yield Trials in India, Pakistan and Bangladesh initiated by the U.S. Agency for International Development Feed the Future initiative and the global testing environments of the Elite Spring Wheat Yield Trials.

The findings, published in Retrospective Quantitative Genetic Analysis and Genomic Prediction of Global Wheat Yields, in Frontiers in Plant Science, found that the Obregón yield testing process in different SEs is very efficient in developing high-yielding and resilient wheat lines for target sites.

The authors found higher average heritabilities, or trait variations due to genetic differences, for grain yield in the Obregón SEs than in the target sites (44.2 and 92.3% higher for the South Asia and global trials, respectively), indicating greater precision in the SE trials than those in the target sites. They also observed significant genetic correlations between one or more SEs in Obregón and all five South Asian sites, as well as with the majority (65.1%) of the Elite Spring Wheat Yield Trial sites. Lastly, they found a high ratio of selection response by selecting for grain yield in the SEs of Obregón than directly in the target sites.

“The results of this study make it evident that the rigorous multi-year yield testing in Obregón environments has helped to develop wheat lines that have wide-adaptability across diverse geographical locations and resilience to environmental variations,” said Philomin Juliana, CIMMYT associate scientist and lead author of the article.

“This is particularly important for smallholder farmers in developing countries growing wheat on less than 2 hectares who cannot afford crop losses due to year-to-year environmental changes.”

In addition to these comparisons, the scientists conducted genomic prediction for grain yield in the target sites, based on the performance of the same lines in the SEs of Obregón. They found high year-to-year variations in grain yield predictabilities, highlighting the importance of multi-environment testing across time and space to stave off the environment-induced uncertainties in wheat yields.

“While our results demonstrate the challenges involved in genomic prediction of grain yield in future unknown environments, it also opens up new horizons for further exciting research on designing genomic selection-driven breeding for wheat grain yield,” said Juliana.

This type of quantitative genetics analysis using multi-year and multi-site grain yield data is one of the first steps to assessing the effectiveness of CIMMYT’s current grain yield testing and making recommendations for improvement—a key objective of the new Accelerating Genetic Gains in Maize and Wheat for Improved Livelihoods (AGG) project, which aims to accelerate the breeding progress by optimizing current breeding schemes.

This work was made possible by the generous support of the Delivering Genetic Gain in Wheat (DGGW) project funded by the Bill & Melinda Gates Foundation and the UK Foreign, Commonwealth & Development Office (FCDO) and managed by Cornell University; the U.S. Agency for International Development’s Feed the Future initiative; and several collaborating national partners who generated the grain yield data.

East Africa partners welcome “new era” in wheat breeding collaboration

Written by Marcia MacNeil on September 15, 2020. Posted in Features.

Representatives from ministries of agriculture and national agricultural research systems (NARS) in Ethiopia and Kenya recently joined funder representatives and technical experts from the International Maize and Wheat Improvement Center (CIMMYT) to renew a long-standing collaboration under the auspices of an ambitious new project, Accelerating Genetic Gains in Maize and Wheat for Improved Livelihoods (AGG).

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, and 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 varieties that are climate-resilient, pest- and disease-resistant, highly nutritious, and targeted to farmers’ specific needs.

Ethiopia and Kenya: CIMMYT’s longstanding partners

The inception meeting for the wheat component of AGG in East Africa drew more than 70 stakeholders from Ethiopia and Kenya: the region’s primary target countries for wheat breeding. These two countries have long-standing relationships with CIMMYT that continue to deliver important impacts. Ninety percent of all wheat in Ethiopia is derived from CIMMYT varieties, and CIMMYT is a key supporter of the Ethiopian government’s goal for wheat self-sufficiency. Kenya has worked with CIMMYT for more than 40 years, and hosts the world’s biggest screening facilities for wheat rust diseases, with up to 40,000 accessions tested each year.

AGG builds on these successes and on the foundations built by previous projects, notably Delivering Genetic Gain in Wheat, led by Cornell University. The wheat component of AGG works in parallel with a USAID-funded “zinc mainstreaming” project, meeting the demand for increased nutritional quality as well as yield and resilience.

CIMMYT Director General Martin Kropff gave key remarks at the stakeholder gathering, which took place Thursday, August 20.

“Cooperation between CIMMYT and Ethiopia and Kenya – as in all the countries where CIMMYT works – has had tremendous impact,” he said. “We are proud, not for ourselves, but for the people we work for: the hundreds of millions of poor people and smallholders who rely on wheat and maize for their daily food and incomes.”

“AGG will raise this spirit of global cooperation to a new level.”

AGG Project Leader and CIMMYT Interim Deputy Director General for Research Kevin Pixley introduced the new project as a “unique and important” project that challenges every stakeholder to grow.

“What we would like to achieve is a step change for all of us, he told the stakeholders. “Each of us has the opportunity and the challenge to make a difference and that’s what we’re striving to do.”

Representatives from the agricultural research communities of both target countries emphasized the significance of their long collaboration with CIMMYT and their support for the project.

The Honorable Mandefro Nigussie, Ethiopia’s State Minister of Agriculture, confirmed the ongoing achievements of CIMMYT collaboration in his country.

“Our partnership with CIMMYT […] has yielded several improved varieties that increased productivity twofold over the last 20 years. He referred to Ethiopia’s campaign to achieve self-sufficiency in wheat. “AGG will make an immense contribution to this. The immediate and intermediate results can help achieve the country’s ambitious targets.”

A holistic and gender-informed approach

Deputy Director of Crops at the Kenya Agriculture and Livestock Organization (KALRO) Felister Makini, representing the KALRO Director General Eliud Kireger, noted the project’s strong emphasis on gender-intentional variety development and gender-informed analysis to ensure female farmers have access to varieties that meet their needs and the information to successfully adopt them.

“The goal of this new project will indeed address KALRO’s objective of enhancing food security and nutrition in Kenya,” she said. “This is because AGG not only brings together wheat breeding and optimization tools and technologies, but also considers gender and socioeconomic insights, which will be pivotal to our envisaged strategy to achieve socioeconomic change.”

Funding partners keen for AGG to address future threats

Before CIMMYT wheat experts took the virtual floor to describe specific workplans and opportunities for partner involvement, a number of funder representatives shared candid and inspiring thoughts.

“We are interested in delivery,” said Alan Tollervey of FCDO, formerly the UK Department for International Development. “That is why we support AGG, because it is about streamlining and modernizing the delivery of products […] directly relevant to both the immediate demands of poor farmers in developing countries and the global demand for food – but also addressing the future threats that we see coming.”

Hailu Wordofa, Agricultural Technology Specialist at the Bureau for Resilience and Food Security at USAID highlighted the importance of global partnerships for past success and reiterated the ambitious targets of the current project.

“We expect to see genetic gains increase and varieties […] replaced by farmer-preferred varieties,” he reminded stakeholders. “To make this happen, we expect CIMMYT’s global breeding program to use optimal breeding approaches and develop strong and truly collaborative relationships with NARS partners throughout the entire process.”

“Wheat continues to be a critical staple crop for global food security and supporting CIMMYT’s wheat breeding program remains a high priority for USAID,” he assured the attendees.

He also expressed hope that AGG would collaborate other projects working in parallel, including the Feed the Future Innovation Lab for Applied Wheat Genomics at Kansas State University, and the International Wheat Yield Partnership.

FFAR Scientific Program Director Jeff Rosichan called AGG a “really ambitious project that takes a comprehensive look at the research gaps and challenges and how to translate that research into farmers’ fields.”

Agriculture prevails even under COVID-19

The global COVID-19 pandemic was not ignored as one of several challenges during this time of change and transition.

“As we speak today, despite the challenge that we have with the COVID-19, I am proud to say that work on the nurseries is on-going. We are able to apply [our] skills and deliver world-class science,” said Godwin Macharia, center director at KALRO-Njoro.

“This COVID-19 pandemic has shown us that there is a great need globally to focus on food equity. I think this project allows that to happen,” said Jeff Rosichan from FFAR.

Transformations are also happening at the research organization and funding level. CIMMYT Director General Martin Kropff noted that “demand-driven solutions” for “affordable, efficient and healthy diets produced within planetary boundaries” are an important part of the strategy for One CGIAR, the ongoing transformation of CGIAR, the world’s largest public research network on food systems, of which CIMMYT is a member.

Hans Braun, director of CIMMYT’s Global Wheat Program reminded attendees that, despite these changes, one important fact remains. “The demand for wheat will continue to grow for many years to come, and we must meet it.”

Collaborating to accelerate genetic gains in maize and wheat

Written by Marta Millere on September 11, 2020. Posted in Features.

Stakeholders in the Accelerating Genetic Gains in Maize and Wheat for Improved Livelihoods (AGG) project have pledged to strengthen efforts to deliver desirable stress tolerant, nutritious and high-yielding maize and wheat varieties to smallholder farmers in a much shorter time. The alliance, comprising funders, national agricultural research systems (NARS), private seed companies, non-governmental organizations, the International Maize and Wheat Improvement Center (CIMMYT) and, for the maize component the International Institute for Tropical Agriculture (IITA), made these assurances during virtual events held in July and August 2020, marking the inception of the 5-year AGG project.

The initiative seeks to fast-track the development of higher-yielding, climate resilient, demand-driven, gender-responsive and nutritious seed varieties for maize and wheat, two of the world’s most important staple crops. The project is funded by the Bill & Melinda Gates Foundation, the Foreign, Commonwealth & Development Office (FCDO), the U.S. Agency for International Development (USAID), and the Foundation for Food and Agriculture Research (FFAR).

Tackling current and emerging threats

Jeff Rosichan, scientific program director of the Foundation for Food and Agricultural Research (FFAR), acknowledged the significant and ambitious aim of the project in tackling the challenges facing maize and wheat currently and in the future. “We are seeing the emergence of new pests and pathogens and viral diseases like never before. A lot of the work of this project is going to help us to tackle such challenges and to be better prepared to tackle emerging threats,” he said.

AGG builds on gains made in previous initiatives including Drought Tolerant Maize for Africa (DTMA), Improved Maize for African Soils (IMAS), Water Efficient Maize for Africa (WEMA), Stress Tolerant Maize for Africa (STMA) and Delivering Genetic Gain in Wheat (DGGW), with support from partners in 17 target countries in sub-Saharan Africa (SSA) and South Asia.

Hailu Wordofa, agricultural technology specialist at the USAID Bureau for Resilience and Food Security, underscored his expectation for CIMMYT’s global breeding program to use optimal breeding approaches and develop strong collaborative relationships with NARS partners, “from the development of product profiles to breeding, field trials and line advancement.”

Similarly, Gary Atlin, senior program officer at the Bill & Melinda Gates Foundation lauded the move toward stronger partnerships and greater emphasis on the CIMMYT and IITA breeding programs. “The technical capacity of partners has increased through the years. It is prudent to ensure that national partnerships continue. It is always a challenging environment, this time multiplied by the COVID-19 crisis, but through this collaboration, there is a greater scope to strengthen such partnerships even more,” he said.

Symbiotic partnerships with great impact

“From the NARS perspective, we are committed to doing our part as primary partners to deliver the right seed to the farmers,” said Godfrey Asea, director of the National Crops Resources Research Institute at the National Agriculture Research Organization (NARO), Uganda. “We see an opportunity to review and to use a lot of previous historical data, both in-country and regionally and to continue making improved decisions. We also reiterate our commitment and support to continuously make improvement plans in our breeding programs.”

Martin Kropff, director general of CIMMYT, recognized the tremendous impact arising from the longstanding cooperation between CIMMYT’s maize and wheat programs and national programs in countries where CIMMYT works. “A wheat study in Ethiopia showed that 90% of all the wheat grown in the country is CIMMYT-related, while an impact study for the maize program shows that 50% of the maize varieties in Africa are CIMMYT-derived. We are very proud of that – not for ourselves but for the people that we work for, the hundreds of millions of poor people and smallholder farmers who really rely on wheat and maize for their living and for their incomes,” he said.

Founder and Chief Executive Officer of East Africa-based Western Seed Company Saleem Esmail expressed optimism at the opportunities the project offers to improve livelihoods of beneficiaries. “I believe we can do this by sharing experiences and by leveraging on the impacts that this project is going to bring, from new technologies to new science approaches, particularly those that help save costs of seed production.”

He, however, observed that while the target of fast-tracking varietal turnover was great, it was a tough call, too, “because farmers are very risk averse and to change their habits requires a great deal of effort.”

On his part, director of Crop Research at the Oromia Agricultural Research Institute (OARI) in Ethiopia Tesfaye Letta revealed that from collaborative research work undertaken with CIMMYT, the institute has had access to better-quality varieties especially for wheat (bread and durum). These have helped millions of farmers to improve their productivity even as Ethiopia aims for wheat self-sufficiency by expanding wheat production under irrigation.

“We expect more support, from identifying wheat germplasm suitable for irrigation, developing disease resistant varieties and multiplying a sufficient quantity of early generation seed, to applying appropriate agronomic practices for yield improvement and organizing exposure field visits for farmers and experts,” he said.

Challenges and opportunities in a time of crisis

Alan Tollervey, head of agriculture research at Foreign, Commonwealth and Development Office (FCDO) and the UK representative to the CGIAR System Council, emphasized the need for continued investment in agricultural research to build a resilient food system that can cope with the demands and pressures of the coming decades. This way, organizations such as CIMMYT and its partners can adequately deliver products that are relevant not only to the immediate demands of poor farmers in developing countries – and the global demand for food generally – but also to address foreseen threats.

“We are at a time of intense pressure on budgets, and that is when projects are most successful, most relevant to the objectives of any organization, and most able to demonstrate a track record of delivery. CIMMYT has a long track history of being able to respond to rapidly emerging threats,” he said.

Felister Makini, the deputy director general for crops at the Kenya Agricultural Research Organization (KALRO) lauded the fact that AGG not only brings together maize and wheat breeding and optimization tools and technologies, but also considers gender and socioeconomic insights, “which will be crucial to our envisioned strategy to achieve socioeconomic change.”

Zambia Agriculture Research Organization (ZARI) maize breeder Mwansa Kabamba noted that the inclusion of extension workers will help to get buy-in from farmers especially as far as helping with adoption of the improved varieties is concerned.

In its lifecycle, the AGG project aims to reduce the breeding cycles for both maize and wheat from 5-7 years currently to 3-4 years. By 2024, at least 150,000 metric tons of certified maize seed is expected to be produced, adopted by 10 million households, planted on 6 million hectares and benefit 64 million people. It also seeks to serve over 30 million households engaged in wheat farming the target countries.

Matching nutrients to agroforestry systems for greater maize and wheat yields

Written by Marta Millere on September 11, 2020. Posted in Features.

Globally, the COVID-19 pandemic and associated lockdowns have created bottlenecks across the agricultural value chain, including disrupting the supply of fertilizer. This could negatively impact the already low yields in smallholders’ fields in the Global South. Livelihoods of these resource-poor farmers and food security of those they feed call for innovations or smarter application of existing knowledge to avoid increasing food insecurity.

In a recent study, a team of scientists from the International Maize and Wheat Improvement Center (CIMMYT) and Plant Production Systems, Wageningen University, found that there are clever ways to mix and match maize and wheat varieties with mineral fertilizers in tree-crop systems for greater nutrient use efficiency. The study explored the impact of different combinations of nitrogen (N) and phosphorus (P) fertilizers on crop yield in tree crop systems. It also identified mineral fertilizer-tree combinations that maximize agronomic nutrient use efficiencies under different contexts.

Tree-crop-fertilizer interactions for wheat growing under Faidherbia albida and maize growing under Acacia tortilis and Grevillea robusta through omission trials of N and P were explored in open fields and fields under tree canopy, using a split plot design. The experiments were conducted under different agroecologies in Ethiopia (Meki and Mojo) and Rwanda, where retaining scattered trees in fields has been practiced for centuries. The trials were replicated four times and over two seasons. Trees with approximately similar ages, crown structures and pruning history were used for a researcher-led and farmer-managed on-farm experiment.

The results demonstrated that different on-farm tree species interact uniquely with crops, resulting in different responses to N and P fertilization. Except for F. albida, perhaps the most ‘ideal’ agroforestry species, the other two tree species under the current study raised the question of tree-crop compatibility for optimum productivity. F. albida significantly improved N and P use efficiencies, leading to significantly higher grain yields in wheat. The P use efficiency of wheat under F.albida was double that of wheat grown in an open field. By contrast, G. robusta and A. tortilis trees lowered nutrient use efficiencies in maize, leading to significantly less maize grain yields compared with open fields receiving the same fertilization. The case study also identified probabilities of critically low crop yields and crop failure to be significantly greater for maize growing under the canopy of these species.

In conclusion, the study demonstrated that tree-crop interactions are mediated by the application of N and P fertilizers in tree-crop systems. In F. albida-wheat agroforestry systems, N fertilizers could be saved, with localized application of P fertilizers close to tree crowns. Such adaptable application may help smallholder farmers cope with COVID-19-imposed fertilizer limitations. In G.robusta-maize and A.tortilis-maize agroforestry systems, maize did not respond to N and P fertilizers applied at recommended rates, although the application of these nutrients compensated for competition. This implies mineral fertilizers can offset the effect of competition, while they fail to provide the yield advantages like mono-cropping situations.

The researchers underlined the fact that fertilizer recommendations need to be adapted to agroforestry systems. However, in order to quantify the exact magnitude and nature of fertilizer-tree interaction in agroforestry systems accurately, factorial application of higher and lower rates of mineral fertilizer is needed. They also called for further research to identify fertilization rates that minimize tree-crop competition for G. robusta-maize and A. tortilis-maize systems, while additional studies are needed to identify the rates and timing of application that optimize F. albida-wheat facilitation.

Development Partners Explore Scaling Up Food Systems Transformation in Africa Post-COVID-19

Written by Mary Donovan on September 10, 2020. Posted in In the media.

The COVID-19 crisis is highlighting many fragilities in contemporary food systems. But the pandemic has also created opportunities for local organizations and technologies to quickly mitigate these fragilities while showcasing the resilience, innovation and adaptation of African food and agricultural systems.

Reaching women with improved maize and wheat

Written by Marcia MacNeil on September 8, 2020. Posted in Features.

By 2050, global demand for wheat is predicted to increase by 50 percent from today’s levels and demand for maize is expected to double. Meanwhile, these profoundly important and loved crops bear incredible risks from emerging pests and diseases, diminishing water resources, limited available land and unstable weather conditions – with climate change as a constant pressure exacerbating all these stresses.

Accelerating Genetic Gains in Maize and Wheat for Improved Livelihoods (AGG) is a new 5-year project led by the International Maize and Wheat Improvement Center (CIMMYT) 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.

Funded by the Bill & Melinda Gates Foundation, the UK Foreign, Commonwealth & Development Office, the U.S. Agency for International Development (USAID) and the Foundation for Food and Agriculture Research (FFAR), AGG fuses innovative methods to sustainably and inclusively improve breeding efficiency and precision to produce seed varieties that are climate-resilient, pest- and disease-resistant, highly nutritious, and targeted to farmers’ specific needs.

AGG seeks to respond to the intersection of the climate emergency and gender through gender-intentional product profiles for its improved seed varieties and gender-intentional seed delivery pathways.

AGG will take into account the needs and preferences of female farmers when developing the product profiles for improved varieties of wheat and maize. This will be informed by gender-disaggregated data collection on current varieties and preferred characteristics and traits, systematic on-farm testing in target regions, and training of scientists and technicians.

To encourage female farmers to take up climate-resilient improved seeds, AGG will seek to understand the pathways by which women receive information and improved seed and the external dynamics that affect this access and will use this information to create gender-intentional solutions for increasing varietal adoption and turnover.

“Until recently, investments in seed improvement work have not actively looked in this area,” said Olaf Erenstein, Director of CIMMYT’s Socioeconomics Program at a virtual inception meeting for the project in late August 2020. Now, “it has been built in as a primary objective of AGG to focus on […] strengthening gender-intentional seed delivery systems so that we ensure a faster varietal turnover and higher adoption levels in the respective target areas.”

In the first year of the initiative, the researchers will take a deep dive into the national- and state-level frameworks and policies that might enable or influence the delivery of these new varieties to both female and male farmers. They will analyze this delivery system by mapping the seed delivery paths and studying the diverse factors that impact seed demand. By understanding their respective roles, practices, and of course, the strengths and weaknesses of the system, the researchers can diagnose issues in the delivery chain and respond accordingly.

Once this important scoping step is complete, the team will design a research plan for the following years to understand and influence the seed information networks and seed acquisition. It will be critical in this step to identify some of the challenges and opportunities on a broad scale, while also accounting for the related intra-household decision-making dynamics that could affect access to and uptake of these improved seed varieties.

“It is a primary objective of AGG to ensure gender intentionality,” said Kevin Pixley, Director of CIMMYT’s Genetic Resources Program and AGG project leader. “Often women do not have access to not only inputs but also information, and in the AGG project we are seeking to help close those gaps.”

Excellence in Agronomy 2030 initiative to launch at African Green Revolution Forum

Written by Mary Donovan on September 4, 2020. Posted in Press releases.

Nine CGIAR centers, supported by the Big Data Platform, will launch the Excellence in Agronomy 2030 initiative on September 7, 2020, during this year’s African Green Revolution Forum (AGRF) online summit.

The Excellence in Agronomy 2030 (EiA 2030) initiative will assist millions of smallholder farmers to intensify their production systems while preserving key ecosystem services under the threat of climate change. This initiative, co-created with various scaling partners, represents the collective resolve of CGIAR’s agronomy programs to transform the world’s food systems through demand- and data-driven agronomy research for development.

EiA 2030 will combine big data analytics, new sensing technologies, geospatial decision tools and farming systems research to improve spatially explicit agronomic recommendations in response to demand from scaling partners. Our science will integrate the principles of Sustainable Intensification and be informed by climate change considerations, behavioral economics, and scaling pathways at the national and regional levels.

A two-year Incubation Phase of EiA 2030 is funded by the Bill & Melinda Gates Foundation. The project will demonstrate the added value of demand-driven R&D, supported by novel data and analytics and increased cooperation among centers, in support of a One CGIAR agronomy initiative aiming at the sustainable intensification of farming systems.

Speaking on the upcoming launch, the IITA R4D Director for Natural Resource Management, Bernard Vanlauwe, who facilitates the implementation of the Incubation Phase, said that “EiA 2030 is premised on demand-driven agronomic solutions to develop recommendations that match the needs and objectives of the end users.”

Christian Witt, Senior Program Officer from the Bill & Melinda Gates Foundation, lauded the initiative as a cornerstone for One CGIAR. “It is ingenious to have a platform like EiA 2030 that looks at solutions that have worked in different settings on other crops and whether they can be applied in a different setting and on different crops,” Witt said.

Martin Kropff, Director General of the International Maize and Wheat Improvement Center (CIMMYT), spoke about the initiative’s goals of becoming the leading platform for next-generation agronomy in the Global South, not only responding to the demand of the public and private sectors, but also increasing efficiencies in the development and delivery of solutions through increased collaboration, cooperation and cross-learning between CGIAR centers and within the broader agronomy R&D ecosystem, including agroecological approaches.

At the EiA 2030 launch, representatives from partner organizations and CGIAR centers will give presentations on different aspects of the project.

CGIAR centers that are involved in EiA include AfricaRice, the International Center for Tropical Agriculture (CIAT), the International Maize and Wheat Improvement Center (CIMMYT), the International Potato Center (CIP), the International Center for Agricultural Research in the Dry Areas (ICARDA), World Agroforestry Center (ICRAF), the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), the International Institute of Tropical Agriculture (IITA), and the International Rice Research Institute (IRRI).

How do I become a zero-till farmer?

Written by Mary Donovan on September 3, 2020. Posted in Videos.

“What you are now about to witness didn’t exist even a few years ago,” begins the first video in a series on zero tillage produced by the International Maize and Wheat Improvement Center (CIMMYT). Zero tillage, an integral part of conservation agriculture-based sustainable intensification, can save farmers time, money and irrigation water.

Through storytelling, the videos demonstrate the process to become a zero till farmer or service provider: from learning how to prepare a field for zero tillage to the safe use of herbicides.

All videos are available in Bengali, Hindi and English.

This videos were produced as part of the Sustainable and Resilient Farming Systems Intensification in the Eastern Gangetic Plains (SRFSI) project, funded by the Australian Centre for International Agricultural Research (ACIAR). The videos were scripted with regional partners and filmed with communities in West Bengal, India.

New publications: Power, agency and benefits among women and men maize farmers

Written by Emma Orchardson on August 27, 2020. Posted in Publications.

For smallholder farmers in sub-Saharan Africa, new agricultural technologies such as improved maize varieties offer numerous benefits — increased incomes, lower workloads and better food security, among others. However, when new technologies are introduced, they can denaturalize and expose gender norms and power relations because their adoption inevitably requires women and men to renegotiate the rules of the game. The adoption of new varieties will often be accompanied by a number of related decisions on the allocation of farm labor, the purchase and use of inorganic fertilizers, switching crops between women- and men-managed plots, and the types of benefit household members expect to secure may change.

In an article published this month in Gender, Technology and Development, researchers from the International Maize and Wheat Improvement Center (CIMMYT) explore how women in Nigeria negotiate these new power dynamics to access and secure the benefits of improved maize varieties and, more broadly, to expand their decision-making space.

Using focus group and interview data collected as part of the GENNOVATE project, the authors draw on case studies from four villages — two in the northern states of Kaduna and Plateau; two in the southwestern state of Oyo — to develop an understanding of the relationship between gender norms, women’s ability and willingness to express their agency, and the uptake of agricultural technologies. “This is an important step toward improving the capacity of agricultural research for development to design and scale innovations,” say the authors. “Achieving this ambition is highly relevant to maize.”

The results were similar across all four sites. The authors found that women in each area were constrained by powerful gender norms which privilege male agency and largely frown upon women’s empowerment, thus limiting their ability to maximize the benefits from improved varieties or realize their agency in other domains.

All women respondents remarked that improved maize varieties were easy to adopt, have higher yields and mature quickly, which meant that income flows started earlier and helped them meet household expenditures on time. They prioritized the contribution of improved maize to securing household food security, which helped them meet their ascribed gender roles as food providers.

“At the same time though, women felt they could not maximize their benefits from improved maize varieties due to men’s dominance in decision-making,” the authors explain. “This was particularly the case for married women.”

“Men are meant to travel far – not women”

Embedded gender norms – particularly those relating to mobility – infuse the wider environment and mean that women’s access to opportunities is considerably more restricted than it is for men.

The findings demonstrate that both women and men farmers secure benefits from improved maize varieties. However, men accrue more benefits and benefit directly, as they have unfettered mobility and opportunity. They can access markets that are further away, and the maize they sell is unprocessed and requires no transformation. Additionally, men do not question their right to devote profits from maize primarily to their own concerns, nor their right to secure a high level of control over the money women make.

On the other hand, women respondents — regardless of age and income cohort — repeatedly stated that while it is hard to earn significant money from local sales of the processed maize products they make, it is also very difficult for them to enter large markets selling unprocessed, improved maize.

The difficulties women face in trying to grow maize businesses may be partly related to a lack of business acumen and experience, but a primary reason is limited personal mobility in all four communities. For example, in Sabon Birni village, Kaduna, women lamented that though the local market is not large enough to accommodate their maize processing and other agri-business ventures, they are not permitted travel to markets further afield where ‘there are always people ready to buy’.

“Women’s benefits relate to the fact that improved maize varieties increase the absolute size of the ‘maize cake’,” say the authors. “They expect to get a larger slice as a consequence. However, the absolute potential of improved varieties for boosting women’s incomes and other options of importance to women is hampered by gender norms that significantly restrict their agency.”

The implications for maize research and development are that an improved understanding of the complex relational nature of empowerment is essential when introducing new agricultural technologies.

Breaking Ground: Erick Ortiz Hernández innovates regional solutions for greater impact

Written by Leslie Domínguez on August 21, 2020. Posted in Features.

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.”

Gender Dynamics in Seed Systems in Sub-Saharan Africa and Worldwide Lessons workshop

Lessons for gender in seed systems

Written by Mary Donovan on August 20, 2020. Posted in Videos.

Seed systems are complex and dynamic, involving diverse, interdisciplinary actors. Women play an important role in the seed value chain, although underlying social and cultural norms can impact their equal participation. Gender-sensitive seed systems will create more opportunities for women and increase food security.

The International Maize and Wheat Improvement Center (CIMMYT) convened a multi-stakeholder technical workshop titled, “Gender dynamics in seed systems in sub-Saharan Africa and worldwide lessons” on December 2, 2019, in Nairobi, Kenya. Researchers and development practitioners operating in the nexus of gender and seed systems shared lessons learned and research findings to identify knowledge gaps and exchange ideas on promising — and implementable — interventions and approaches that expand opportunities for women in the seed sector.

The missing link between maize seeds and trust

Written by Mary Donovan on August 18, 2020. Posted in Features.

The world population is expected to rise to almost 10 billion by 2050. To feed this number of people, we need to increase food production while using fewer resources. Biofortification, the process of fortifying staple crops with micronutrients, could help to solve this problem.

However, it is not that easy to identify biofortified seeds.

Often, the process of biofortification does not change a seed in a visible way, opening the possibilities for counterfeit products. Farmers cannot verify that the seeds they buy are as advertised. Unsurprisingly, fake seeds are a major obstacle to the adoption of biofortified crops. Similarly, in the process from farm to fork, traceability of biofortified food is equally difficult to achieve.

Picture Aisha, a smallholder farmer in Nigeria. She’s in the market for biofortified maize seeds for her farm. How does she know which seeds to pick, and how can she be sure that they are actually biofortified?

One solution is blockchain technology.

What is blockchain?

Blockchain is a shared digital ledger for record keeping, where data is decentralized and allocated to users. Digital information, or blocks, is stored in a public database, or chain.

This technology platform helps in situations of lack of trust. It provides an unhackable, unchangeable and transparent record of events where users place trust in computer code and math, instead of a third party. This code writes the rules of the system and the software is peer-reviewed, so rules and data are resilient against corruption. When new data is added to the database, actors in then network verify and timestamp the data before adding it to the blockchain. After input, no one can change the information. No single entity owns or controls the database, allowing actors to trust in the system without having to trust any other actors.

While often associated with bitcoin and cryptocurrencies, blockchain technology has many other uses in traditional industries, including the potential to transform agri-food systems. The Community of Practice on Socio-economic Data, led by the International Maize and Wheat Improvement Center (CIMMYT), produced a report detailing the role blockchain can play in agri-food systems and biofortified seeds.

Blockchain for agri-food systems

Agri-food systems consist of complex networks that often mistrust each other. Blockchain technology can enhance transparency, traceability and trust. It could have a significant role to play in closing the yield gap and reducing hunger.

Many transactions done in the agri-food sector have paper records. Even when records are digital, disconnected IT systems create data silos. Blockchain enables stakeholders to control, manage and share their own data, breaking down silos.

For example, blockchain technology can help solve issues of land governance, unclear ownership and tenure by providing an accurate land registration database. It can help with compliance to standards from governments or private organizations. This technology could make financial transactions more efficient, limit corruption, and provide provenance, traceability and recall of products.

Verifying biofortified maize seeds

HarvestPlus conducted a study to understand the barriers to widespread adoption of biofortified seeds. The team interviewed 100 businesses and 250 individuals from farmers to global brands about their experiences with biofortification. Unsurprisingly, they found that a big barrier to adoption is the inability to distinguish biofortified crops from standard ones.

Therefore, it is crucial to have a system to verify biofortified seeds. HarvestPlus collaborated with The Fork to investigate solutions.

One solution is a public blockchain. The result could look like this: Aisha, our smallholder farmer in Nigeria wants to buy biofortified maize seeds for her farm. At the store, she takes a phone out of her pocket and scans a QR code on a bag to see a trustworthy account of the seeds’ journey to that bag. Satisfied with the account, she brings verified biofortified maize seeds home, improving nutrition of her family and community.

Contingent on farmers having access to smartphones, this situation could be possible. However, blockchain technology will not solve everything, and it is important we test and study these solutions while considering other challenges, such as access to technology and human behavior.

The Community of Practice on Socio-economic Data report, Blockchain for Food, gives principles of digital development of blockchain. It is crucial to understand the existing ecosystem, design for scale, build for sustainability and design the technology with the user. These are crucial points to consider when developing blockchain solutions for agri-food systems.

As the global food system is beginning to transition towards more transparency, circularity and customization, blockchain technology could play a major role in how this shift evolves. A new testing and learning platform for digital trust and transparency technologies in agri-food systems, including blockchain technology, was launched in February 2020. The platform will build capacity of the potential of this technology and ensure that it is usable and inclusive.

The theme for International Youth Day 2020, Youth Engagement for Global Action, highlights the various ways in which the engagement of young people at local, national and global levels enriches national and multilateral institutions and processes.

Up to 60% of Africa’s youth face challenges such as limited employment opportunities, financial constraints to access land and adequate technical equipment. However, agriculture is increasingly providing options. Through it, young people are participating and leveraging on new technologies that can optimize farming systems and create employment.

This photo essay depicts youth in on-farm and off-farm activities across East and Southern Africa. These young men and women are innovators and adopters of improved technologies such as small scale mechanization, appropriate farming practices, employment opportunities and research innovations implemented by the International Maize and Wheat Improvement Center (CIMMYT).
