Tangible agricultural solutions shine at first online AGRF

For ten years now, the African Green Revolution Forum (AGRF) has been an unmissable event. Every September, the premier forum for African agriculture has brought people together to share experiences about transforming agriculture, raising productivity for farmers and increasing incomes.

The theme of the 2020 summit — Feed the Cities, Grow the Continent: Leveraging Urban Food Markets to Achieve Sustainable Food Systems in Africa — was a call to action to rethink our food systems to make them more resilient and deliver better nourishment and prosperity for all.

This year, the summit went virtual. Delegates could not mingle, visit booths and network over lunch, but attendance reached new heights. Over 10,400 delegates from 113 countries participated in this edition of the AGRF, compared to 2,300 delegates last year.

As in the previous years, CGIAR centers, including the International Maize and Wheat Improvement Center (CIMMYT), maintained an active presence among speakers and attendees.

With over 50 projects and hundreds of staff based across nine countries, Africa holds a significant position in CIMMYT’s research agenda. CIMMYT’s work in Africa helps farmers access new maize and wheat system-based technologies, information and markets, raising incomes and enhancing crop resilience to drought and climate change. CIMMYT sets priorities in consultation with ministries of agriculture, seed companies, farming communities and other stakeholders in the maize and wheat value chains.

Striving for excellence

CGIAR leveraged AGRF 2020’s highly diversified and international audience to launch the Excellence in Agronomy 2030 initiative (EiA 2030) on September 7, 2020. EiA’s impressive group of experts plans to hit the ground running in 2020 and work toward speeding up progress in tailoring and delivering nutrients and other agronomic solutions to smallholder farmers in Africa and other regions.

“Across agricultural production systems, low crop yields and inadequate incomes from agriculture are the rule rather than the exception,” said Martin Kropff, Director General of CIMMYT and Chair of One CGIAR Transition Advisory Group (TAG) 2 on Research. “At the same time, the ‘asks’ of agriculture have evolved beyond food security. They now include a broader range of Sustainable Development Goals, such as sustainable land management, climate change mitigation, provision of heathy diets, and inclusive economic growth. None of these goals will be achieved without the large-scale adoption of improved and adapted agronomic practices. To this end, we have initiated the creation of a CGIAR-wide EiA 2030 initiative aiming at reducing yield and efficiency gaps for major crops at scale.”

EiA 2030 is funded by the Bill & Melinda Gates Foundation, supported by the Big Data Platform and co-created by AfricaRice, CIAT, CIMMYT, CIP, ICARDA, ICRAF, ICRISAT, IITA and IRRI.

Scaling agriculture beyond numbers

On September 7, 2020, a group of experts, including Lennart Woltering, Scaling Catalyst at CIMMYT and chair of the Agriculture and Rural Development (ARD) working group of the Community of Practice on Scaling, gathered to explore how organizations are supporting scaling food systems in a post-COVID-19 world.

As Martin Kropff mentioned in a video address, One CGIAR aims to deliver on its commitments by building on its experience with pioneering integrated development projects, such as CSISA, CIALCA and AVISA. “One CGIAR plans to be actively involved and help partners to scale by delivering on five One CGIAR impact areas at the regional level. How? By taking integrated regional programs from strategic planning to tactical implementation in three steps: strategic multi-stakeholder demand-driven planning process, tactical plan development based on the integration of production and demand, and implementation of multi-stakeholder innovation hubs. An integrated regional approach will deliver at scale,” Kropff said.

“CIMMYT has developed different scenarios regarding what agri-food systems will look like in 2025 with the COVID-19 shock. Whatever may unfold, integrated systems are key,” highlighted Bram Govaerts, Director of the Integrated Development Program and one of CIMMYT’s interim Deputy Directors General for Research, during the session.

“Diversity and proactive mindsets present at the #AGRF2020 High-Level Ministerial Roundtable.

Putting healthy diets on the roundtable

Later in the week, CIMMYT experts took part in two key events for the development of Africa’s agriculture. Govaerts stepped in for Kropff during the High-Level Ministerial Roundtable, where regional leaders and partners discussed reaching agricultural self-sufficiency to increase the region’s resilience toward shocks such as the ongoing pandemic.

At the Advancing Gender and Nutrition policy forum, Natalia Palacios, Maize Quality Specialist, spoke about engaging nutritionally vulnerable urban consumers. Palacios echoed the other speakers’ calls for transforming agri-food systems and pointed out that cereals and effective public-private partnerships are the backbone of nutritionally vulnerable and poor urban customers’ diets.

According to the Food and Agriculture Organization of the UN, in 30 years, the population of Africa is projected to double to a number as high as 2.7 billion, from 1.34 billion in 2020. Considering only the projected population, by 2050 Africa will have to supply 112.4 to 133.1 million tons of wheat and 106.5 to 126.1 million tons of maize to ensure food security of the burgeoning population. “We are living in a very challenging time because we need to provide affordable, nutritious diets — within planetary boundaries,” Palacios said.

Wheat blast has made the intercontinental jump to Africa

Wheat blast, a fast-acting and devastating fungal disease, has been reported for the first time on the African continent. In an article published in the scientific journal PLoS One, a team of scientists confirmed that symptoms of wheat blast first appeared in Zambia during the 2018 rainy season, in experimental plots and small-scale farms in the Mpika district, Muchinga province.

Researchers from the International Maize and Wheat Improvement Center (CIMMYT), the US Department of Agriculture – Foreign Disease Weed Science Research Unit (USDA-ARS) and the Zambian Agricultural Research Institute (ZARI) participated in this study.

Wheat blast poses a serious threat to rain-fed wheat production in Zambia and raises the alarm for surrounding regions and countries on the African continent with similar environmental conditions. Worldwide, 2.5 billion consumers depend on wheat as a staple food and, in recent years, several African countries have been actively working towards reducing dependence on wheat imports.

“This presents yet another challenging biotic constraint to rain-fed wheat production in Zambia,” said Batiseba Tembo, wheat breeder at ZARI and lead scientist on the study.

A difficult diagnosis

“The first occurrence of the disease was very distressing. This happened at the spike stage, and caused significant losses,” Tembo said. “Nothing of this nature has happened before in Zambia.”

Researchers were initially confused when symptoms of the disease were first reported in the fields of Mpika. Zambia has unique agro-climatic conditions, particularly in the rainfed wheat production system, and diseases such as spot blotch and Fusarium head blight are common.

“The crop had silvery white spikes and a green canopy, resulting in shriveled grains or no grains at all
 Within the span of seven days, a whole field can be attacked,” Tembo explained. Samples were collected and analyzed in the ZARI laboratory, and suspicions grew among researchers that this may be a new disease entirely.

Tembo participated in the Basic Wheat Improvement Course at CIMMYT’s global headquarters in Mexico, where she discussed the new disease with Pawan Singh, head of Wheat Pathology at CIMMYT. Singh worked with Tembo to provide guidance and the molecular markers needed for the sample analysis in Zambia, and coordinated the analysis of the wheat disease samples at the USDA-ARS facility in Fort Detrick, Maryland, United States.

All experiments confirmed the presence of the fungus Magnaporthe oryzae pathotype Triticum (MoT), which causes the disease.

“This is a disaster which needs immediate attention,” Tembo said. “Otherwise, wheat blast has the potential to marginalize the growth of rain-fed wheat production in Zambia and may threaten wheat production in neighboring countries as well.”

Wheat blast spreads through infected seeds and crop residues, as well as by spores that can travel long distances in the air. The spread of blast within Zambia is indicated by both mechanisms of expansion.

A cause for innovation and collaboration

CIMMYT and the CGIAR Research Program on Wheat (WHEAT) are taking action on several fronts to combat wheat blast. Trainings and international courses invite participants to gain new technical skills and knowledge in blast diagnostics, treatment and mitigation strategies. WHEAT scientists and partners are also studying the genetic factors that increase resistance to the disease and developing early warning systems.

“A set of research outcomes, including the development of resistant varieties, identification of effective fungicides, agronomic measures, and new findings in the epidemiology of disease development will be helpful in mitigating wheat blast in Zambia,” Singh said.

“It is imperative that the regional and global scientific communities join hands to determine effective measures to halt further spread of this worrisome disease in Zambia and beyond,” Tembo expressed.

Partners in nutrition

It is no secret that Africa is urbanizing at breakneck speed. Consider Lagos. In 1950 the Nigerian city boasted a population of a few hundred thousand. Today that number has soared to around 14 million. It is estimated that by 2025 half of Africa’s population will live in urban areas.

This demographic transformation has had dramatic consequences for human health and nutrition. Urban dwellers are far more likely to rely on cheap highly-processed foods, which are shelf-stable but poor on nutrients.

These statistics, presented by moderator Betty Kibaara, Director of the Food Initiative at The Rockefeller Foundation, framed the 2020 African Green Revolution Forum’s policy symposium on “Advancing Gender and Nutrition.” The forum comprised two tracks. One focused on addressing the needs of nutritionally vulnerable urban consumers, particularly women; the other on gender-based financing in the African agri-food system

Speaking in the first track, Natalia Palacios, maize quality specialist at the International Maize and Wheat Improvement Center (CIMMYT), underlined the enormity of the challenge. “We need to provide affordable, nutritious diets … within planetary boundaries,” she said.

Many of the panelists pointed out further dimensions of the challenge — from evidence deficits around the continent’s urban populations to the amplifying effects of the COVID-19 crisis. Palacios stressed that the bedrock of any response must be effective partnerships between governments, companies and non-profit actors working in this area.

“The really important thing is to start working together,” she said, “to start developing the strategies together instead of providing things or demanding things.” Speaking to the role of organizations like CIMMYT, Palacios highlighted the need to work closely with the private sector to understand the demand for agricultural raw materials that can be converted into nutritious diets.

Rich nutrition within reach

Palacios’ most recent research efforts focus on precisely this question. She and a team of researchers, including CIMMYT senior scientist Santiago Lopez-Ridaura, explored how various innovations in maize production have improved the macro- and micro-nutrient content of the grain and led to healthier maize-based agri-food systems.

This is significant because for millions of the estimated 2 billion people globally who suffer from “hidden hunger” a more diversified diet rich in costly, perishable, nutrient-dense foods is not economically feasible. In low- and middle-income countries across Africa, Asia and Latin America, it estimated that rice, maize and wheat account for 55 to 70% of calories.

CIMMYT, HarvestPlus and the International Institute of Tropical Agriculture (IITA), together with several stakeholders, have been deeply involved in work to improve the nutritional quality of staple-dependent food systems. In partnership with a broad network of national and private-sector partners, they have released over 60 improved maize and wheat varieties fortified with zinc or provitamin A in 19 countries.

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.

A track record of delivering local solutions with a global perspective

The CGIAR Research Program on Wheat (WHEAT) has “a track record of delivering local solutions with a global perspective — and is well positioned to continue this trajectory in the next decade.”

This was a key finding of a recent review of the program aimed to assess WHEAT’s 2017-2019 delivery of quality science and effectiveness, as well as to provide insights and lessons to inform the program’s future.

“Wheat as a crop is bound to be central to global food security in the foreseeable future,” the reviewers stated.

The crop currently contributes 20% of the world population’s calories and protein — and global demand is estimated to increase by 44% between 2005-07 and 2050.

WHEAT — led by the International Maize and Wheat Improvement Center (CIMMYT) with the International Center for Agricultural Research in the Dry Areas (ICARDA) as a key research partner — has two pillars that are essential to meeting this demand: raising potential yield through breeding and closing the yield gap through sustainable intensification at field, farm and landscape scales.

Key recommendations included supporting strategic investment in research partner network development and maintenance and continuing WHEAT’s trajectory towards modernizing breeding processes and integrating sustainable intensification approaches, including mechanization.

The reviewers warned of challenges for the way ahead, pointing out that partnerships — and WHEAT’s reputation as a reliable partner — are vulnerable to funding volatility. The review also raised concerns about the potential fragmentation of the global breeding program, restrictions to the international exchange of germplasm and ideas, “misguided” emphasis on minor crops, and CGIAR’s “focus on process at the expense of results.”

“This review cuts to the core of what’s so critical — and at risk — not only with our program but wheat research in general,” said Hans Braun, director of CIMMYT’s Global Wheat Program and the CGIAR Research Program on Wheat. “Global collaboration and the exchange of improved seeds, data, and especially information.”

“The reviewers rightly point out that limited resources will lead to competition and dampen this collaboration — even between scientists in the same program. We must address this potential risk to improve integration and continue our life saving work,” Braun explained.

“In most of the developing world, the alliance of public sector and CGIAR wheat breeding programs, as well as some national public breeding programs on their own, will remain dominant providers of wheat varieties, until either functioning seed royalty collection systems are established and/or hybrid wheat becomes a reality,” he said.

WHEAT’s strength is its robust global network of research for development partners and scientists linked to global breeding in a ‘wide adaptation’ approach,” said Victor Kommerell, program manager for the CGIAR Research Programs on Maize and Wheat.

“This review underscores that breaking up the breeding program could cause lasting damage to this network,” Kommerell said.

More key findings of the review include:

  • WHEAT is effective and well-managed: In 2017-2019, WHEAT mainly achieved its planned outputs and outcomes and in addition achieved unplanned outcomes. For the three years reviewed, WHEAT did not drop any research line.
  • WHEAT’s strength is its partnerships: WHEAT has catalyzed a global network of research and development (R&D) that has delivered and continues to deliver a disproportionate wealth of outputs in relation to investment.
  • WHEAT creates, and thrives on, collaboration: The predominantly public nature of wheat R&D (In the period 1994-2014, the public sector accounted for 63% of global wheat varietal releases and more than 95% of releases in developing countries) favors collaboration, compared with other industries.
  • WHEAT facilitates shared success: The long history of collaboration between CIMMYT, ICARDA and national partners has fostered a sense of belonging to the International Wheat Improvement Network that permits free exchange of information and germplasm, allowing the best varieties to be released, irrespective of origin. International nursery testing delivers elite lines for national program use; data shared by national programs informs WHEAT’s next crossing cycle.

CRP Maize Annual Report 2019

The CGIAR Research Program on Maize (MAIZE) is proud to release its 2019 Annual Report.

Around the world, the COVID-19 crisis has emphasized the need to strengthen food systems while improving the food security and livelihoods for the most vulnerable, especially the resource-constrained smallholder farmers.

In 2019 MAIZE and its partners made great advances in the development of improved stress-tolerant maize varieties, continued their battle against fall armyworm in both Africa and Asia, and maintained their focus on sustainable intensification of maize-based cropping systems in sub-Saharan Africa, South Asia and Latin America where maize plays a critical role in food and nutritional security, income and livelihoods of millions of resource-constrained smallholders and consumers. We look forward to continued productive collaborations as we transition with our partners into an integrated, inclusive One CGIAR designed to meet the UN Sustainable Development Goals.

Led by the International Maize and Wheat Improvement Center (CIMMYT), with the International Institute of Tropical Agriculture (IITA) as its main CGIAR Consortium partner, MAIZE focuses on increasing maize production for the 900 million poor consumers for whom maize is a staple food in Africa, South Asia and Latin America.

CGIAR breeding programs need more than just tech upgrades — they need change management

Did you know that vehicles with steering wheels on the left are often cheaper to make than right hand-drive cars? They are mass-produced in much larger batches. But many drivers and governments were just unwilling to change to this dominant design.

We humans are not so adept at change. Instead of embracing novel ways of thinking, we’d rather stick to the old ones. We cling onto what is safe, what is familiar or what we are already good at. We see this in the workplace, in our personal lives and in society as a whole. The world still can’t agree on using the metric system!

Within the domain of plant breeding, we are both driving and responding to rapid change. It is mesmerizing to visualize the changes gene editing is about to deliver, not to mention what genomic prediction is already delivering. We are being challenged on every single aspect of plant breeding.

Change of a different sort is about to cascade through the world’s main network of agricultural research centers — which includes centers at the global forefront of plant breeding. CGIAR is embarking on a transition into a much more integrated One CGIAR organization.

An overarching goal of this integration is no other than to ensure breeding improvement plans — and the changes they aim to drive — are implemented as seamlessly and quickly as possible. The Excellence in Breeding Platform is both driving and supporting this change among CGIAR centers and international and national partners.

The case for change in plant breeding programs

Plant breeders are in fact missing some vital opportunities. For example, there continues to be a rather limited use of real market insights to inform resource allocation within programs. This in turn results in a selection of traits weighted towards what breeders and associated scientists think are needed, which may not necessarily meet actual market needs.

With new goals and structures foisting change on breeding programs, their success depends on one thing above all else: savvy change management. Fortunately, there are some steps we can take to manage change well.

1. Drive out complacency with a sense of urgency

Most change management efforts fail when insufficient urgency is built early enough in the process. But this urgency can be the most effective antidote against complacency. Organizations that have either secured a very dominant and successful position in the market, or lack effective and threatening competition, can very easily slide into a sense of self-righteousness and an inward-looking perspective.

Although CGIAR breeding efforts could be thought of as an example of the latter — lacking competitors — seasoned managers in industry and marketing like to think that “there is no such thing as a lack of competition.” Funding, for one, is by nature a competition. Funding agencies might look at other fields and/or players to support if they deliver a higher return on investment, not only financially but also socially.

The impact of high complacency cultures can be seen in plant breeding. For instance, a rather large number of breeding programs still lack a high enough rate of what is called “elite x elite crosses.” Unless breeding pipelines run on such crosses, they achieve less than optimal genetic gains and delivery at the field. And donors get a lesser return on investment. Moreover, this complacency means not delivering the best varieties smallholder farmers need to support their families.

The parable of the slowly boiling frog is oftentimes used to portray the consequences of complacency. In any complacency-filled organization, no matter how intelligent, educated and well-intentioned its members are, change is often dead on arrival.

You may already have an inkling of what it takes to create enough urgency: bold and sometimes risk-taking leadership. For instance, some years ago, Unilever was one of the first global companies to decouple its financial growth from its environmental footprint, and it established the then outrageous sounding goal of halving its environmental footprint by 2030.

A good urgency-raising example that could inspire our line of work may be this one: let’s renew at least 50% of a current portfolio of cultivars within the next five years in a given Target Population of Environments (TPE). A second could be: let’s deploy sparse testing in at least 90% of field trials within six months.

To create urgency we need to articulate the gap between opportunities available, and the current ability of the organization to pursue such opportunities. But we must also spell out — upfront — the risks if we don’t bridge such a gap.

2. Build a guiding coalition

These days, driving change is too complex to be led by single individuals. We live in fast-paced times. And situations are full of evident and not-so-evident links among myriad moving pieces. We cannot expect one individual to be able to gather enough information fast enough, and then to consistently make the right decisions. Instead, a guiding coalition is needed, with sufficient determination, commitment and thought diversity. Such coalitions require five traits: a position of power, credibility, leadership, expertise, and individual egos held at bay. Once such teams are assembled, the main drivers of success are having a common goal, and enough trust and safety so the real issues are unearthed and addressed.

3. Develop a vision and a strategy

When leadership tries to drive change by applying dated approaches such as micromanagement or an authoritarian stance, plans are likely to fail upon arrival. These methods may breed compliance, but certainly not a fierce and sincere commitment. Because of the extreme uncertainty and organizational survival being at stake, crafting a vision plays a bigger role during change management than during business as usual.

Two main aspects of developing a vision are especially relevant to CGIAR breeding programs.

Firstly, academic and R&D organizations often keep doing what has worked well in the past. But any change management effort ought to be very explicit about what it is known as “strategic dismissal.” This is the ability to stop and phase out activities no longer providing enough value, or where the outcomes of which are not wanted/needed by funding agencies or beneficiaries. For instance, programs investing in developing hybrid cultivars for the first time in a crop could downsize previous cultivar development efforts. Alternatively, they could scale down efforts in countries that have their own strong local breeding programs. These changes are no small feat, but the inability to phase out activities clashes with the very first posit of any effective strategy: don’t just “keep doing.”

Secondly, a vision provides an invisible fabric that pulls all efforts together in a cohesive way. Therefore, its scope is much wider than most people realize, stretching across strategies, plans, and the budgets and means needed to exert change at the depth and speed needed.

4. Encourage constructive confrontation

One characteristic of a complacent organization stands out: a rather low-candor, low-confrontation culture. No one needs excessively high-confrontation, “take no prisoners”, toxic cultures. But low-confrontation cultures tend to breed under-performance, status quo maintenance and deeply ingrained complacency. And perhaps the most negative consequence is that they fail to instill a strong enough sense of ownership and accountability among its members.

Change is coming (it has arrived already…)

Yes, change is hard, but it is coming. Maybe not for drivers of right-hand drive cars. But certainly for those who want to modernize and optimize their breeding programs. Now is the time for us to invest in a smart and forward-looking change management processes.

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

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.

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.”

Crop-loss Assessment Monitor: A multi-model and multistage decision support system

This article by Sakshi Saini and Paresh B Shirsath was originally published on the CCAFS website.

Farming has often been quoted as one of the noblest professions, shouldering the responsibility of feeding the world; yet it has been globally identified as one of the most perilous industries associated with a high vulnerability rate. Crop insurance has been established worldwide to provide social protection to farmers and reduce their vulnerability. While the emergence of crop insurance schemes around the world indicates commitment to secure the livelihoods of farmers, they often lack accurate seasonal crop growth monitoring and timely yield loss estimation, making the authentication of crop insurance claims more challenging.

Crop loss assessments are often done via crop cutting experiments (CCEs). However, these can suffer from human error and moral hazard. The experiments also require significant capital and human resources, and need to be carried out simultaneously, in a limited period of time. This often leads to inadequate and delayed claim payment, high premium rates, and poor execution of crop insurance schemes.

With technological advancements and availability, crop growth monitoring and productivity assessment can not only be more accurate and efficient but also less resource-intensive. Readily available data and technology, such as detailed weather data, remote sensing, modeling and big data analytics can be instrumental in further improving crop insurance mechanisms. The CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS) has developed a Crop-loss Assessment Monitor (CAM) tool as an integrated solution that uses technologies to improve loss assessment and make crop insurance more efficient.

The Crop-loss Assessment Monitor (CAM) tool

The CAM tool integrates multiple input data and methods for crop loss assessment at multiple times in the season. It uses different models for loss assessment depending on the time or stage in the season. To ensure user-friendliness, the tool was developed with a simple, easy-to-use interface and produces outputs customized for policy and risk management agencies. It uses freely available R libraries and does not require specific software installations and high-power processing engines, which in general are a prerequisite to process large gridded satellite data.

CAM provides a form-based user-interface to carry out the analysis. The user can log in and undertake analysis using multiple methods for a specified region and time. The tool allows users to choose between area-based yield insurance and weather-based index insurance. For insurance analysis, scheme details like sum insured and calamity years can be specified for calculation of threshold yields, premiums and claims.

CAM also includes tabs that provide ‘deviation in the weather’ and ‘deviation in satellite vegetation indices’ to help monitor crop conditions every fortnight. The tool also allows users to identify the model agreement between the four different methods for loss assessment, which strengthens the confidence levels in loss assessments, and related insurance analytics.

A single integrated framework

The tool combines agro-meteorological statistical analysis, crop simulation modelling and optimization techniques, and employs near real-time monitoring by using publicly available satellite products. It is also equipped to capture yield variability.

Highlighting the importance of this tool Dr. Pramod Aggarwal, lead author of the paper and CCAFS Asia Program Leader, notes that “assimilating relevant technologies into a single integrated framework is a good way to determine crop losses. Its deployment can assist in multi-stage loss assessment and thus provide farmers with immediate relief for sowing failure, prevented sowing and mid-season adversity apart from final crop loss assessment.”

The tool addresses three major challenges faced by existing crop insurance schemes; more efficient weather indices, timely estimate of loss assessment and improved contract design. As the tool readily uses freely available technology and data, it requires less capital and human resource compared to crop cutting experiments for crop loss assessment. This tool offers a robust mechanism that further reduces the chances of human errors, and makes the process more transparent, robust and reliable. Therefore, it enables timely relief for farmers facing challenges such as sowing failure, prevented sowing and mid-season adversity.

Massive-scale genomic study reveals wheat diversity for crop improvement

Researchers working on the Seeds of Discovery (SeeD) initiative, which aims to facilitate the effective use of genetic diversity of maize and wheat, have genetically characterized 79,191 samples of wheat from the germplasm banks of the International Maize and Wheat Improvement Center (CIMMYT) and the International Center for Agricultural Research in the Dry Areas (ICARDA).

Collaborating to accelerate genetic gains in maize and wheat

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

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.

Researchers working on the Seeds of Discovery (SeeD) initiative, which aims to facilitate the effective use of genetic diversity of maize and wheat, have genetically characterized 79,191 samples of wheat from the germplasm banks of the International Maize and Wheat Improvement Center (CIMMYT) and the International Center for Agricultural Research in the Dry Areas (ICARDA).

The findings of the study published today in Nature Communications are described as “a massive-scale genotyping and diversity analysis” of the two types of wheat grown globally — bread and pasta wheat — and of 27 known wild species.

Wheat is the most widely grown crop globally, with an annual production exceeding 600 million tons. Approximately 95% of the grain produced corresponds to bread wheat and the remaining 5% to durum or pasta wheat.

The main objective of the study was to characterize the genetic diversity of CIMMYT and ICARDA’s internationally available collections, which are considered the largest in the world. The researchers aimed to understand this diversity by mapping genetic variants to identify useful genes for wheat breeding.

From germplasm bank to breadbasket

The results show distinct biological groupings within bread wheats and suggest that a large proportion of the genetic diversity present in landraces has not been used to develop new high-yielding, resilient and nutritious varieties.

“The analysis of the bread wheat accessions reveals that relatively little of the diversity available in the landraces has been used in modern breeding, and this offers an opportunity to find untapped valuable variation for the development of new varieties from these landraces”, said Carolina Sansaloni, high-throughput genotyping and sequencing specialist at CIMMYT, who led the research team.

The study also found that the genetic diversity of pasta wheat is better represented in the modern varieties, with the exception of a subgroup of samples from Ethiopia.

The researchers mapped the genomic data obtained from the genotyping of the wheat samples to pinpoint the physical and genetic positions of molecular markers associated with characteristics that are present in both types of wheat and in the crop’s wild relatives.

According to Sansaloni, on average, 72% of the markers obtained are uniquely placed on three molecular reference maps and around half of these are in interesting regions with genes that control specific characteristics of value to breeders, farmers and consumers, such as heat and drought tolerance, yield potential and protein content.

Open access

The data, analysis and visualization tools of the study are freely available to the scientific community for advancing wheat research and breeding worldwide.

“These resources should be useful in gene discovery, cloning, marker development, genomic prediction or selection, marker-assisted selection, genome wide association studies and other applications,” Sansaloni said.
