A sustainable agrifood systems approach in conflict-ridden Sudan

Sudan, the third largest country in Africa, has long been an epicenter of food production, due to its fertile lands and rich history of agricultural cultivation. But modern Sudan faces chronic food insecurity rooted in social and geopolitical challenges. A situation that has been exacerbated by the outbreak of war on April 15, 2023. The armed conflict has caused a sudden, further decline in agricultural productivity, displacing large populations and pushing millions of Sudanese into high levels of malnutrition and food insecurity.

In response to this crisis, CIMMYT, through the USAID-funded Sustainable Agrifood Systems Approach for Sudan (SASAS), is supporting agricultural development by creating robust and sustainable food production systems. SASAS adapts a modular and multi-crop approach to implement an integrated agrifood system that underpins food security, employment, and equity.

As the planting season of 2024 approaches, the project strives to strengthen food production to support the people of Sudan during these challenging times.

Experts speak: SASAS focuses on five key areas

Abdelrahman Kheir, SASAS chief of party, highlights how the agricultural innovations of the project are impacting multiple regions in Sudan. The focus of the project is on five broad intervention areas: promoting agricultural production for smallholder farmers, improving value chains and business development, supporting community management of natural resources, and providing horticultural and livestock services such as vaccination campaigns.

Further in the video, Murtada Khalid, country coordinator for Sudan, explains how the SASAS Food Security Initiative (SFSI) will provide 30,000+ farmers with a diversified package of four inputs: fertilizer, seeds, land preparation, and agricultural advisory services, to prepare for the upcoming 2024 sorghum and groundnut planting season. SFSI is a critical element of SASAS that uniquely provides agricultural development aid during a time of conflict to directly improve the food security situation in Sudan.

How women farmers benefit from SASAS

SASAS works directly with women farmers and pastoralists to ensure an equitable approach to food security in the country. Hear farmers from the women-led El-Harram Agricultural Cooperative in Kassala, Sudan, explain how SASAS has positively impacted their lives and families.

Ali Atta Allah, a farmer in Kassala expresses her gratitude for SASAS support. “They provided us with seeds including jute, mallow, okra, and sweet pepper. We planted them, and they thrived.” Ali highlighted the financial gains—a bundle of jute mallow sells for 500 Sudanese Pound (SDG). The income from the entire area amounts to 200,000 to 300,000 SDG. “The seeds provided by SASAS are of superior quality,” she affirmed.

Aziza Haroun from El-Ghadambaliya village, shares her story of how improved seeds provided by SASAS activities helped double her yields compared to previous years. “We used to farm in the same land and the yield was poor. Mercy Corps, a SASAS partner, introduced us to a new method of planting legumes as natural fertilizer. Now our yield has increased significantly,” she said.

Gridded crop modeling to simulate impacts of climate change and adaptation benefits in ACASA

Global temperatures are projected to warm between 1.5-2 degrees Celsius by the year 2050, and 2-4 degrees Celsius by 2100. This is likely to change precipitation patterns, which will impact crop yields, water availability, food security, and agricultural resilience.

To prepare for these challenges, Atlas of Climate Adaptation in South Asian Agriculture (ACASA) uses process-based simulation models that can predict crop growth, development, and yield in order to understand the response of crops to climate change. Models such as Decision Support System for Agrotechnology Transfer (DSSAT), InfoCrop, and Agricultural Production Systems Simulator (APSIM) facilitate the field scale study of the biophysical and biochemical processes of crops under various environmental conditions, revealing how they are affected by changing weather patterns.

The ACASA team, along with experts from Columbia University and the University of Florida, met for a three-day workshop in January 2024 to boost the work on spatial crop modeling. The aim was to design a modeling protocol through a hands-on demonstration on high-performance computers. When scientifically executed, gridded spatial crop modeling–even though complex and data-intensive–can be a great way to frame adaptation and mitigation strategies for improving food security, which is one of ACASA’s goals.

Decisions on data

The group decided to use DSSAT, APSIM, and InfoCrop for simulating the impact of climatic risks on crops such as rice, wheat, maize, sorghum, millet, pigeon pea, chickpea, groundnut, soybean, mustard, potato, cotton, and more. They chose harmonized protocols across all three models with standard inputs, such as conducting simulations at 0.05 degrees. The model input data about weather, soil, crop varietal coefficients, and crop management are being collected and processed for model input formats at 5 kilometer (km) spatial resolution.

A Python version called DSSAT-Pythia is now available to accelerate spatial and gridded applications. The programming for implementing InfoCrop on the Pythia platform is in progress. InfoCrop has been proven in India for past yield estimations, climate change spatial impact, and adaptation assessments for 12 crops.

For other crucial modeling components, a work plan was created including developing regional crop masks, crop zones based on mega-commodity environments as defined by CGIAR, production systems, crop calendars, and irrigated areas by crop. Genetic coefficients will then be calculated from measured past values and recent benchmark data of varietal units.

With this information, several adaptation options will be simulated, including changes in planting dates, stress-tolerant varieties, irrigation, and nitrogen fertilizer (quantity, methods, and technology), residue/mulching, and conservation tillage. The team will evaluate impact and adaptation benefits on yields, water, and nitrogen-use efficiency based on the reported percentage change from the baseline data.

As the project progresses, this work will make strides towards realizing food security for the planet and increasing the resilience of smallholder farming practices.

Harnessing econometric and statistical tools to support climate-resilient agriculture

Globally, climate extremes are adversely affecting agricultural productivity and farmer welfare. Farmers’ lack of knowledge about adaptation options may further exacerbate the situation. In the context of South Asia, which is home to rural farm-based economies with smallholder populations, tailored adaptation options are crucial to safeguarding the region’s agriculture in response to current and future climate challenges. These resilience strategies encompass a range of risk reducing practices such as changing the planting date, Conservation Agriculture, irrigation, stress-tolerant varieties, crop diversification, and risk transfer mechanisms, e.g., crop insurance. Practices such as enterprise diversification and community water conservation are also potential sector-specific interventions.

Atlas of Climate Adaptation in South Asian Agriculture (ACASA) aims to identify hazard-linked adaptation options and prioritize them at a granular geographical scale. While doing so, it is paramount to consider the suitability of adaptation options from a socioeconomic lens which varies across spatial and temporal dimensions. Further, calculation of scalability parameters such as economic, environmental benefit, and gender inclusivity for prioritized adaptation are important to aid climatic risk management and developmental planning in the subcontinent. Given the credibility of econometric and statistical methods, the key tenets of the approach that are being applied in ACASA are worth highlighting.

Evaluating the profitability of adaptation options

Profitability is among the foremost indicators for the feasible adoption of any technology. The popular metric of profitability evaluation is benefit-to-cost ratio. This is a simple measure based on additional costs and benefits because of adopting new technology. A benefit-to-cost ratio of more than one is considered essential for financial viability. Large-scale surveys such as cost of cultivation and other household surveys can provide cost estimates for limited adaptation options. Given the geographical and commodity spread, ACASA must resort to the meta-analysis of published literature or field trials for adaptation options. For example, a recent paper by International Food Policy Research Institute (IFPRI) based on meta-analysis shows that not all interventions result in a win-win situation with improvements in both tradable and non-tradable outcomes. While no-till wheat, legumes, and integrated nutrient management result in an advantageous outcome, there are trade-offs between the tradable and non-tradable ecosystem services in the cases of directed seed rice, organic manure, and agroforestry2.

Quantification of adaptation options to mitigate hazards

Past studies demonstrate the usefulness of econometric methods when analyzing the effectiveness of adaptation options such as irrigation, shift in planting time, and crop diversification against drought and heat stress in South Asia. Compared to a simple cost-benefit approach, the adaptation benefits of a particular technology under climatic stress conditions can be ascertained by comparing it with normal weather conditions. The popular methods in climate economics literature are panel data regression and treatment-based models. Subject to data availability, modern methods of causal estimation, and machine learning can be used to ascertain the robust benefits of adaptation options. Such studies, though available in literature, have compared limited adaptation options. A study by the Indian Council of Agricultural Research-National Institute of Agricultural Economics and Policy Research (ICAR-NIAP), based on ‘Situation Assessment Survey of Agricultural Households’ of National Sample Survey Office (NSSO), concluded that though crop insurance and irrigation effectively improve farm income and reduce farmers’ exposure to downside risk, irrigation is more effective than crop insurance1.

Statistical models for spatial interpolation of econometric estimates

Since ACASA focuses on gridded analysis, an active area of statistical application is the spatial interpolation or downscaling of results to a more granular scale. Many indicators used for risk characterization are available at coarser geographical units or points from surveys. Kriging is a spatial interpolation method where there is no observed data. Apart from spatial interpolation of observed indicators, advanced Kriging methods can be potentially used to interpolate or predict the estimates of the econometric model.

ACASA’s approach involves prioritizing adaptation options based on suitability, scalability, and gender inclusivity. Econometric and statistical methods play a crucial role in evaluating the profitability and effectiveness of various adaptation strategies from real world datasets. Despite challenges such as limited observational data and integration of econometric and statistical methods, ACASA can facilitate informed decision-making in climate risk management and safeguard agricultural productivity in the face of climatic hazards.

Unlocking insights from literature: exploring adaptation options in ACASA

To address the vulnerability of increased climate risks which impact agriculture, it is imperative to identify location-specific adaptation options. Atlas of Climate Adaptation in South Asian Agriculture (ACASA) is working on identifying commodity specific hazards at different geographical regions and the key adaptation options aligned with geography and hazards. This has been done for major cereal crops (rice, wheat, and maize), coarse grains (millets), oilseeds (coconut, mustard), legumes and vegetable crops (chickpea, potato), livestock, and fisheries. In ACASA, Systematic Literature Review (SLR) serves as a fundamental tool to identify key climate adaptation options and assess their effectiveness, considering agroecological factors.

Literature reviews are a customary approach for researchers to grasp existing knowledge and findings. The SLR methodically establishes clear research objectives, employs structured search queries to identify relevant literature, applies defined exclusion criteria, and extracts data for scientific analysis. This structured approach facilitates mapping the literature, validating findings, identifying gaps, and refining methodologies thereby minimizing biases, and ensuring comprehensive coverage of evidence.

Commodity-specific research questions, aligned with the problem/population, intervention, comparison/consequences, outcome, and time PICO(T) framework, have been used to guide the search process. By utilizing keywords specific to these questions, ACASA sourced literature from reputable databases such as Web of Science, Scopus, Google Scholar, and local databases of South Asian countries: Bangladesh, India, Nepal, and Sri Lanka. Local databases and gray literature further bolstered the understanding of local conditions and broadened the coverage of studied literature.

Systematic Literature Review (SLR)

The searched literature was then filtered using the well-established Preferred Reporting Items for Systematic Reviews and Meta Analysis (PRISMA) framework. PRISMA provides a minimum set of evidence-based literature to be used for further analysis. Let us look at maize as an example of a commodity under analysis in ACASA. For maize, a total of 1,282 papers were identified and based on four exclusion criteria pertaining to adaptation options, quantitative assessment, hazard, and risk only of which 72 papers were shortlisted. The PRISMA framework supported in getting a manageable dataset for in-depth analysis while ensuring transparency in the overall filtering process.

After filtering through PRISMA, a bibliometric analysis was conducted which contained research trend analysis, regional distribution patterns, adaptation option categorizations, and a co-occurrence analysis. Useful patterns in popularity of studied adaptation options, hazards, and their linkages were observed through this analysis. For instance, drought was the most studied hazard, while pest diseases and economics were major hazard impacts studied for the maize literature. In terms of adaptation options, stress tolerant varieties were the most popular adaptation option. Further, co-occurrence analysis provided linkages between adaptation options and hazards, and demonstrated that researchers have also studied bundled technologies.

SLR helped understand the effectiveness of certain adaptation options. Going ahead, this step will be fully realized through a “meta-analysis” which will be pivotal in quantifying the evidence and prioritizing adaptation options for different agroecologies. SLR has proven to be an effective research method to build a comprehensive database that can be used across different thematic areas of ACASA. Adaptation options enlisted through SLR can be further substantiated through expert elicitations via heurism, crop modelling, cost-benefit analysis, and other important pillars of ACASA to identify efficient and cost-effective options.

SLR also provided the ACASA team with the opportunity to identify certain literature gaps such as uneven geographical coverage and excessive emphasis on certain adaptation options versus the rest. Conceptualization of systematically reviewing climate adaptation options in the South Asian context by integrating bibliometric and meta-analysis adds novelty to the current efforts of ACASA.

With agricultural diversification, more is better

Over the last seventy years, intensively managed monocultures, focused on maximizing calorie production, have become a dominant approach to global food production. This trend toward simplification in agricultural systems has supported productivity gains but has very troubling consequences for the environment including nutrient pollution and biodiversity loss at a massive scale. Restoring diversity is essential to regaining ecological balance.

Monocultures are generally all the same, turning biologically-rich systems into chemical-intensive engineered ones nearly devoid of life forms other than those yielding a genetically identical commodity crop. Their guiding principle is producing food ingredients as cheaply as possible. Biologically diversified agricultural systems can take many forms. Their guiding principle is recapturing resilience and resource use efficiency while supplying balanced diets and viable livelihoods.

In recent years, there have been many efforts to biologically diversify farming systems. Increasing the number of species and the genetic diversity is associated with improved resilience and resource use efficiency.

A new paper published in Science consolidates evidence from across a wide range of diversification strategies, applied on five continents, to understand how they affect environmental and social outcomes. These strategies encompass many different interventions ranging from crop rotations and cover crops to livestock inclusion to use of compost, hedgerows, and contour farming.

The study shows that the likelihood of environmental and social benefits goes up when a greater number of diversification strategies are combined. Importantly, the environmental benefits of diversification were found to be greatest in very simplified landscapes with less than 20% in non-crop area.

It also found that applying multiple diversification strategies in tandem reduces tradeoffs. In other words, the path to agricultural win-wins leads to diversified working landscapes, not just diversification strategies on individual farms.

The push toward commodity monocultures has been baked into many agricultural policies, such as subsidies and trade deals, and into land tenure systems. The monoculture bias is also reinforced through pricing, payment, and other supply chain arrangements. Even research agendas have encouraged monoculture with the long-term emphasis on yield-focused breeding.

It’s time to dismantle the structural barriers that leave so many farmers just getting by “against the odds” and at the expense of functioning ecosystems.

Successful surveillance results in early first detection of Ug99 in South Asia

The detection of the Ug99 wheat stem rust strain TTKTT in Nepal showcases the effectiveness of CIMMYT-led global surveillance efforts. Identified early through diligent field surveys by Nepal’s NPPRC and NWRP and confirmed by Denmark’s GRRC, this proactive response helped prevent further spread. Despite no subsequent detections in South Asia, the case underlines the importance of ongoing surveillance and development of resistant wheat varieties, supported by international initiatives.

Planning the future of South Asian wheat

In each country, CIMMYT and NARS leaders held a one-day meeting to review and plan their wheat improvement partnership, with attendance from 25-30 wheat scientists in each country. The sessions aimed to review and identify bottlenecks to the wheat impact pathway in each country, describe recent changes in the breeding programs of CIMMYT and NARS partners, and prioritize and agree updates to the NARS-CIMMYT wheat improvement collaborations.

NARS partners highlighted their wheat improvement programs through field visits to research stations. Visitors attended Wheat Research Institute (ARI), Faisalabad and National Agricultural Research Center (NARC), Islamabad in Pakistan; National Wheat Research Program (NWRP), Bhairahawa and National Plant Breeding & Genetics Research Center (NPBGRC), Khumaltar in Nepal; and Indian Institute of Wheat and Barley Research (IIWBR), Punjab Agricultural University (PAU), Borlaug Institute for South Asia (BISA), and the Indian Agricultural Research Institute (IARI) in India.

The GWP team also visited: Faisalabad Agricultural University, with a special focus on collaborative zinc biofortification work in Pakistan; farmers’ fields in Nepal to see participatory evaluations of elite wheat lines (candidates for release as new varieties) and to hear from farmers about challenges and expectations from improved varieties; and the Lumbini Seed Company to learn about the crucial role of seed companies, bottlenecks, and opportunities in the pathway from research to impact in farmers’ fields.

NARS scientists and directors in all three countries were enthusiastic about the opportunities for enhanced partnership to adopt some of the modernizing technologies that AGG has brought to CIMMYT. Partners are especially keen to –

  1. Receive earlier generation varieties, segregating breeding lines to empower them to select in their own environments.
  2. Model and explore strategies to shorten their breeding cycles.
  3. Apply quantitative genetics tools to better select parents for their crossing blocks.
  4. Adopt experimental designs that improve efficiency.
  5. Explore opportunities for co-implementing improvement programs through shared testing schemes, communities of practice (e.g. for quantitative genetics or use of exotic germplasm to address challenges from climate change), and more.
A highlight of the trip in Nepal: visiting on-farm trials, where farmers share insights about their preferences for improved varieties, where they often mentioned tolerance over lodging. (Photo: CIMMYT)

“The visit provided CIMMYT and NARS wheat scientists with the opportunity to exchange experiences and ideas, and to explore ways of enhancing collaborations that will strengthen our joint impact on wheat farmers and consumers,” said Pixley.

Following these visits, the Bangladesh Wheat and Maize Research Institute (BWMRI) soon reached out to CIMMYT to request a similar review and planning meeting, with a vision to modernize and strengthen their wheat improvement partnership.
