CIMMYT calls for direct agricultural investment to address Sudan’s food crisis

Written by Julian Bañuelos-Uribe on June 26, 2024. Posted in Press releases.

Nairobi, Kenya — 26 June 2024 — CIMMYT calls upon the global community to take immediate and decisive action to address the worsening food crisis in Sudan. As the country teeters on the brink of a famine that could surpass the devastating Ethiopian famine of the 1980s, CIMMYT emphasizes the critical need for both emergency food aid and long-term investment in Sudanese agriculture.

Urgent humanitarian needs and long-term solutions

Recent reports indicate that the ongoing civil war in Sudan has created the world’s most severe humanitarian crisis, with millions of people facing acute food shortages due to the impact of climate change, blocked aid deliveries, failing agricultural systems and infrastructure, and continued conflict. In response, CIMMYT highlights the necessity of balancing emergency aid with sustainable agricultural development to prevent recurring food crises.

“The escalating food crisis in Sudan demands not only immediate emergency assistance but also strategic investment in the country’s agricultural sector to ensure food security and stability,” said Director General of CIMMYT, Bram Govaerts. “We must break away from the aid-dependency model and support Sudanese farmers directly, empowering them to rebuild their livelihoods and contribute to the nation’s recovery as well as todays food availability.”

CIMMYT’s commitment to Sudanese agriculture

CIMMYT, alongside other international organizations and NGOs, has been actively working in Sudan to support farmers and improve agricultural productivity as part of the Sustainable Agrifoods Systems Approach to Sudan (SASAS) project in collaboration with USAID. With the outbreak of the civil war, SASAS has pivoted to be acutely focused on interventions that support and underpin food security in Sudan, with 13 partners operating across 7 States as the largest operating consortium on-the-ground in the country. Activities range from the provision of improved seeds and agricultural technologies to vaccination campaigns and community resource (water, land) management.

Investing in agricultural resilience

CIMMYT’s initiatives have shown significant impact, even amidst conflict. For example, the Al Etihad women-led farmer cooperative in South Kordofan has empowered its members to improve their production and incomes through collective resource management, training on best practice farming techniques, provision of agricultural inputs, and structured business planning. This cooperative model is essential for building resilience and ensuring food security in Sudanese communities.

“Sudan’s need for food assistance is growing exponentially, but donors have provided only 3.5 percent of requested aid. This gets the story backwards. Food insecurity is at the root of many conflicts. Peace remains elusive without well-functioning agricultural systems, and it is unreasonable to expect viable agricultural production without peace,” Govaerts stated.

Call for global action

CIMMYT urges the international community to –

Increase funding: Support the UN humanitarian appeal for Sudan, which has received only 16% of the necessary funds.
Facilitate aid deliveries: Press all parties in the conflict to allow unobstructed humanitarian access, particularly through critical routes such as the Adré crossing from Chad.
Invest in agriculture: Commit to immediate agricultural development by supporting Sudanese farmers with training, resources, and infrastructure improvements so they can produce locally the needed food.
Do not forget: It is easy to overlook the war in Sudan with more publicized conflicts in Gaza and Ukraine. Leaders must continue to highlight the challenges Sudan faces and the global reverberation of their precarious food security situation.

A path forward

The confluence of conflict, climate change, and economic instability has overwhelmed Sudan. However, by investing directly in the country’s agricultural sector, the international community can help break the cycle of crisis, fostering economic activity and political stability. Let us not forget, no food without peace and you cannot build peace on empty stomachs, so no peace without food.

Global experts unite to strengthen plant health management in the Global South

Supporting the growth of local maize seed industries: Lessons from Mexico

Written by Steven M on March 8, 2022. Posted in Features.

Over the past several decades, maize breeders have made considerable strides in the development and deployment of new hybrids. These offer higher yields compared to older varieties and reduce the risks farmers face from the vagaries of a changing climate and emerging pest and disease threats. But, for small-scale farmers to adopt new, improved climate-resilient and stress-tolerant maize hybrids at scale, they must be first available, accessible and their benefits need to be widely understood and appreciated. This is where vibrant national seed industries potentially play an important role.

Prior to the 1990s, government agencies tended to play the lead role in hybrid production and distribution. Since then, expectations are that the private sector — in particular locally owned small-scale seed enterprises — produce maize hybrids and distribute them to farmers. When successful, local seed industries are able to produce quality new hybrids and effectively market them to farmers, such that newer hybrids replace older ones in agrodealer stores in relatively short periods of time. If small seed enterprises lack capacities or incentives to aggressively market new hybrids, then the gains made by breeding will not be realized in farmers’ fields. By monitoring seed sales, breeders at CIMMYT and elsewhere, as well as seed business owners, gain insights into smallholders’ preferences and demands.

A recent publication in Food Security assesses the capacities of 22 small and medium-sized seed enterprises in Mexico to produce and market new maize hybrids. The study draws on the experience of the MasAgro project, a decade-long development whereby the International Maize and Wheat Improvement Center (CIMMYT), in partnership with Mexico’s Department of Agriculture and Rural Development (SADER), engaged with dozens of locally owned seed businesses to expand their portfolio of maize hybrids.

The authors, led by CIMMYT senior economist Jason Donovan, highlight the critical role the MasAgro project played in reinvigorating the portfolios of maize seeds produced by small and medium-sized enterprises. MasAgro “filled a gap that had long existed in publicly supported breeding programs” by providing easy access to new cultivars, available to local seed companies without royalties or branding conditions, and without the need for seed certification. The enterprises, in turn, showed a remarkably high capacity to take up new seed technology, launching 129 commercial products between 2013 and 2017.

“Without doubt the MasAgro project can be considered a success in terms of its ability to get new maize germplasm into the product portfolios of small seed companies throughout Mexico,” Donovan said.

The authors also delve into the challenges these maize enterprises faced as they looked to scale the new technologies in a competitive market that has long been dominated by multinational seed enterprises. They observed a lack of access to physical capital, which in turn evidenced a lack of financial capital or access to credit, as well as limited marketing know-how and capacity to integrate marketing innovations into their operations. While most maize enterprises identified the need to expand sales of new commercial products, “signs of innovation in seed marketing were limited” and most of them relied heavily on sales to local and state governments.

According to Donovan, “The MasAgro experience also shows that a strong focus on the demand side of formal seed systems is needed if breeding programs are to achieve greater impact in less time. This implies more attention to how farmers decide on which seed to purchase and how seed companies and seed retailers market seed to farmers. It also implies strong coordination between public sector to make building the local seed industry a national imperative.”

Beyond the Mexican context, the paper’s findings may be of particular interest to development organizations looking to supply local seed industries facing strong competition from regional and multinational companies. One example is the effort to support small seed businesses in Nepal, which face strong competition from larger Indian companies with long histories of engagement in Nepalese seed markets. There are also important lessons for policymakers in eastern and southern Africa, where strict controls over seed release and certification potentially lead to higher production costs and slower rates of introduction of new products by local maize seed companies.

New research highlights opportunities to deepen engagement with private sector for increasing impact from cereal breeding

Written by Marcia MacNeil on February 3, 2022. Posted in News.

A newly published special issue in the journal Outlook on Agriculture features views and experiences on seed systems performance in Sub-Saharan Africa and options to drive faster uptake of new crop varieties. The contributions reflect the breadth of perspectives and expertise within CGIAR and beyond and make the case for the need for more demand-oriented variety development and seed delivery.

A seed system refers to the various actors, processes, and relationships that allow for the production, conservation, exchange and use of propagation materials for crops, trees, forages, livestock, and fish. For the International Maize and Wheat Improvement Center (CIMMYT), seed systems involve private seed companies, retailers, and government research agencies, among others, that are involved in the design, testing, production and distribution of high-yielding, climate-resilient, and pest- and disease-resistant maize hybrids.

“A well-functioning seed system is critical for ensuring that farmers have reliable access to the quality seeds that they want. It forms the critical link between breeders and the small-scale farmers responsible for much of the food production in Sub-Saharan Africa, Latin America and South Asia,” said CIMMYT Senior Economist Jason Donovan, who co-authored the introductory article.

“The papers in this collection raise important issues which up to now have not received enough attention, to include the strategies, capacities and incentives of the private sector to invest in the distribution of new varieties. The topics discussed have implications for the One CGIAR in its ongoing efforts to develop a coherent and coordinated seed system research program that supports accelerated varietal uptake and turnover through effective seed delivery,” he added.

CIMMYT researchers contributed two papers, one which looks at the role of different types of seed producers and traders in shaping seed systems performance and another which proposes new directions for research on gender and formal maize seed systems. The special edition grew out of the CGIAR Community of Excellence for Seed Systems Development where CIMMYT led the discussion on seed value chains and private sector linkages.

One consensus among the authors is that a wider range of partnerships will be required to reenforce the potential of seed systems to delivery more new varieties to small-scale farmers in less time.

Workshop introduces new wheat farmer support project in Ethiopia

Written by Enawgaw Sisay on October 26, 2021. Posted in News.

The Adaptation, Demonstration, and Piloting of Wheat Technologies for Irrigated Lowlands of Ethiopia (ADAPT-Wheat) project was launched on October 19, 2021, with an inception workshop held in Adama, Ethiopia.

The project, led by the International Maize and Wheat Improvement Center (CIMMYT), aims to transform the irrigated lowlands of Ethiopia’s Awash valley from a cotton monoculture to a cotton-wheat rotation. This transformation will improve local wheat production and make important strides towards helping the country reach its goal of wheat self-sufficiency.

Wheat is the second most important staple crop in Ethiopia and a major pillar for food security. CIMMYT has a longstanding role in helping Ethiopia’s wheat farmers adopt improved, high-yielding, and disease-resistant varieties. This close collaboration became evident in 2018, when DNA fingerprinting analysis showed that 87% of all wheat varieties grown in Ethiopia are CIMMYT-derived.

Thanks to improved farmer access to better varieties, the adoption of a number of agronomic practice recommendations, conducive marketing, and strong supply chains, domestic wheat production and productivity in Ethiopia have nearly doubled over the past 15 years. Nevertheless, due to population growth, higher incomes, and accelerated urbanization, the demand for wheat in Ethiopia is increasing faster than productivity.

Scientists believe wheat grain yields of four tons per hectare are possible in low land areas—which include the Afar and Oromia regions—if wheat production is increased through appropriate mechanization, proven agronomic practices, and high-yielding, early-maturing, heat-tolerant, rust-resistant wheat varieties.

When the three-year ADAPT-Wheat project is fully implemented, it will contribute to Ethiopia’s goal for wheat self-sufficiency by 2023.

A space for discussion

At the launch event, participants gathered to share feedback and experiences, identify gaps, and clarify roles and responsibilities among the implementing partners. The meeting also allowed project leaders to confirm participating kebeles (small administrative units), and plan and endorse project activities.

“The forum was a good opportunity to speak about irrigated wheat, get to know each other, and understand the role of each office and its contribution to the success of the project,” said Bekele Abeyo, wheat breeder and CIMMYT’s Country Representative for Ethiopia.

Participants in the workshop included scientists from a number of Ethiopian research institutes, representatives of public and private seed enterprises, heads of bureaus of Agriculture (including those of the Afar and Oromia regions), and local administrations, and representatives of Germany’s Agency for International Cooperation (GIZ).

The discussion included an introduction of CIMMYT and an overview of its global impact, history, and current activities in Ethiopia. An overview of the ADAPT-Wheat project’s objectives, outputs, activities, impact pathways, partners and management was also presented in the forum.

Participants also discussed the key agronomy, breeding, and mechanization activities that will be assessed, validated, scaled up, and scaled out during the project in seven districts, two in the Afar region and five in the Oromia region.

“The inception and planning workshop has a common understanding on how to tackle the bottlenecks ahead of the implementation of the project. The forum was a good opportunity for implementing partners to make a commitment for the new project by realizing the contribution of lowland irrigated wheat in achieving the goal of wheat self-sufficiency by 2023,” Bekele said.

Breaking Ground: Gokul Paudel finds the best on-farm practices for South Asia

Written by Madeline Dahm on December 18, 2020. Posted in Features.

Gokul Paudel is an agricultural economist working to streamline farming practices in South Asia. He seeks to understand, learn from and improve the efficiency of on-farm management practices in a vast variety of ways. Although he joined the International Improvement Center for Wheat and Maize (CIMMYT) right after university, Paudel’s on-farm education started long before his formal courses.

“I was born in a rural village in Baglung district, in the mid-hills of Nepal. My parents worked on a small farm, holding less than half a hectare of land,” he says. “When I was a kid, I remember hearing that even though Nepal is an agricultural country, we still have a lot of food insecurity, malnutrition and children who suffer from stunting.”

“I would ask: How is Nepal an agricultural country, yet we suffer from food insecurity and food-related problems? This question is what inspired me to go to an agricultural university.”

Paudel attended Tribhuvan University in Nepal, and through his coursework, he learned about plant breeding, genetic improvement and how Norman Borlaug brought the first Green Revolution to South Asia. “After completing my undergraduate and post-graduate studies, I realized that CIMMYT is the one organization that contributes the most to improving food security and crop productivity in developing countries, where farmers livelihoods are always dependent on agriculture,” he explains.

Approaching the paradox

Paudel is right about the agriculture and food paradox of his home country. Almost two thirds of Nepal’s population is engaged in agricultural production, yet the country still has shockingly high numbers in terms of food insecurity and nutritional deficiency. Furthermore, widespread dissemination of unsustainable agronomic practices, like the use of heavy-tilling machinery, present similar consequences across South Asia.

If research and data support the claim that conservation agriculture substantially improves crop yields, then why is the adoption of these practices so low? That is exactly what Paudel seeks to understand. “I want to help improve the food security of the country,” he explains. “That’s why I joined the agricultural sector.”

Paudel joined CIMMYT in 2011 to work with the Socioeconomics Program (SEP) and the Cereal Systems Initiative for South Asia (CSISA), providing regional support across Bangladesh, India and Nepal.

His work is diverse. Paudel goes beyond finding out which technological innovations increase on-farm yield and profit, because success on research plots does not always translate to success on smallholder fields. He works closely with farmers and policy makers, using surveys and high-tech analytical tools such as machine learning and data mining to learn about what actually happens on farmers’ plots to impact productivity.

A growing future for conservation agriculture

Over the last two decades, the development of environmentally sustainable and financially appealing farming technologies through conservation agriculture has become a key topic of agronomic research in South Asia.

“Conservation agriculture is based on three principles: minimum disturbance of the soil structure, cover crop and crop rotation, especially with legumes,” Paudel explains.

Leaving the soil undisturbed through zero-till farming increases water infiltration, holds soil moisture and helps to prevent topsoil erosion. Namely, zero-till farming has been identified as one of the most transformative innovations in conservation agriculture, showing the potential to improve farming communities’ ability to mitigate the challenges of climate change while also improving crop yields.

Still, the diffusion rate of zero-tillage has remained low. Right now, Paudel’s team is looking at a range of factors — such as farmers’ willingness to pay, actual demand for new technologies, intensification under input constraints, gender-disaggregated preferences and the scale-appropriateness of mechanization — to better understand the low adoption rates and to find a way to close the gap.

Can farm mechanization ease South Asia’s labor shortage?

In South Asia, understanding local contexts is crucial to streamlining farm mechanization. In recent years, many men have left their agricultural jobs in search of better opportunities in the Gulf countries and this recent phenomenon of labor out-migration has left women to take up more farming tasks.

“Women are responsible for taking care of the farm, household and raising their children,” says Paudel. “Since rural out-migration has increased, they have been burdened by the added responsibility of farm work and labor scarcity. This means that on-farm labor wages are rising, exacerbating the cost of production.”

The introduction of farm machinery, such as reapers and mini-tillers, can ease the physical and financial burden of the labor shortage. “Gender-responsive farm mechanization would not only save [women’s] time and efforts, but also empower them through skills enhancement and farm management,” says Paudel. However, he explains, measures must be taken to ensure that women actually feel comfortable adopting these technologies, which have traditionally been held in the male domain.

From farm-tech to high-tech

Right now, amidst the global lockdown due to COVID-19, Paudel’s field activities are highly restricted. However, he is capitalizing on an opportunity to assess years’ worth of data on on-farm crop production practices, collected from across Bangladesh, India and Nepal.

“We are analyzing this data-set using novel approaches, like machine learning, to understand what drives productivity in farmers’ fields and what to prioritize, for our efforts and for the farmers,” he explains.

Although there are many different aspects of his work, from data collection and synthesis to analysis, Paudel’s favorite part of the job is when his team finds the right, long-lasting solution to farmers’ production-related problems.

“There’s a multidimensional aspect to it, but all of these solutions affect the farmer’s livelihood directly. Productivity is directly related to their food security, income and rural livelihoods.”

A changing landscape

About 160 km away from where he lives now, Paudel’s parents still own the farm he grew up on — though they no longer work on it themselves. They are proud to hear that his work has a direct impact on communities like theirs throughout the country.

“Every day, new problems are appearing due to climate change — problems of drought, flooding and disease outbreak. Though it’s not good news, it motivates me to continue the work that I’m doing,” says Paudel. “The most fascinating thing about working at CIMMYT is that we have a team of multidisciplinary scientists working together with the common goal of sustainably intensifying the agricultural systems in the developing world.”

Training, surveillance, and monitoring to mitigate the threat of wheat blast disease in Bangladesh and beyond

Written by Emma Orchardson on April 21, 2020. Posted in Uncategorized.

Wheat blast (Magnaporthe oryzae pathotype Triticum, or MoT) was first discovered in Brazil in 1985. Since then, it has spread across central and southern Brazil, parts of Bolivia, Paraguay, and Argentina. Grain sterility caused by the disease can significantly reduce wheat yield, with reductions as high as 32% in some parts of Brazil, even with up to two fungicide applications.

The disease appeared in Bangladesh unexpectedly in 2016 and re-emerged in 2017. Wheat area consequently dropped from 62,763 hectares in 2016 to just 14,238 hectares a year later. Suitable climatic conditions in South Asia warn that wheat blast will be a long-term problem.

Some 300 million people in South Asia consume over 100 million tons of wheat annually. Wheat blast therefore presents a significant threat to food security. Compounding these problems, climate change and the evolution of wheat blast – increasing virulence, fungicide resistance and sexual recombination – present further threats.

This project responds to these problems by working to mitigate the effect of wheat blast in South Asia and South America and limit the risk of further spread of this threat, with an emphasis on training, surveillance and monitoring to mitigate the threat of wheat blast disease in Bangladesh and beyond.

Objectives

Improve upon a preliminary modeling framework to manage data requirements for automated time- and spatially-explicit wheat blast outbreak early warning systems (EWS)
Improve flowering predictability to more accurately gauge disease risk
Demonstrate the performance of wheat blast resistant and zinc biofortified variety BARI Gom 33 in farmers’ fields.

Big data analytics for climate-smart agricultural practices in South Asia (Big Data2 CSA)

Written by Emma Orchardson on April 21, 2020. Posted in Uncategorized.

Heterogeneity in soils, hydrology, climate, and rapid changes in rural economies including fluctuating prices, aging and declining labor forces, agricultural feminization, and uneven market access are among the many factors that constrain climate-smart agriculture (CSA) in South Asia’s cereal-based farming systems.

Most previous research on CSA has employed manipulative experiments analyzing agronomic variables, or survey data from project-driven initiatives. However, this can obscure the identification of relevant factors limiting CSA, leading to inappropriate extension, policy, and inadequate institutional alignments to address and overcome limitations. Alternative big data approaches utilizing heterogeneous datasets remain insufficiently explored, though they can represent a powerful alternative source of technology and management practice performance information.

In partnership with national research systems and the private sector in Bangladesh, India and Nepal, Big data analytics for climate-smart agricultural practices in South Asia (Big Data²CSA) is developing digital data collection systems to crowdsource, data-mine and interpret a wide variety of primary agronomic management and socioeconomic data from tens of thousands of smallholder rice and wheat farmers.

The project team analyzes these data by stacking them with spatially-explicit secondary environmental, climatic and remotely sensed data products, after which data mining and machine learning techniques are used to identify key factors contributing to patterns in yield, profitability, greenhouse gas emissions intensity and resilience.

These approaches however must be practical in order for them to be useful in agricultural development and policy. As such, the project’s analytical results will be represented through interactive web-based dashboards, with gender-appropriate crop management advisories deployed through interactive voice recognition technologies to farmers in Bangladesh, India and Nepal at a large-scale. Big Data² CSA is supported by the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS) Flagship 2 on Climate-Smart Technologies and Practices.

Objectives

Develop ICT tools enabling digital collection of crop management data and a cloud-based database that can be managed by next-users
Support advanced degree-level students to engage in field and data science research
Create a digital data collection platform enabling crowd sourcing of crop management information to evaluate contributions to CSA
Create interactive and customizable web-based dashboards presenting post-season research results and providing CSA management recommendations
Organize CSA and big data policy briefings on mainstreaming processes and policy workshops
