A new greenhouse complex, built with financial support from the International Maize and Wheat Improvement Center (CIMMYT), at the Bangladesh Wheat and Maize Research Institute (BWMRI) was inaugurated on 13 August 2022. The greenhouse was built at BWMRI’s headquarters in Dinajpur, Bangladesh.
This complex has a room for generator, a sample preparation room and space for a small laboratory. These upgrades will add new momentum for greenhouse activities and BWMRI and CIMMYT scientists designed the facility to accommodate wheat scientists from Bangladesh and other countries.
The BWMRI has been working to combat wheat blast disease since 2016, with financial and technical support from CIMMYT and other investors. CIMMYT has also assisted the Government of Bangladesh in developing an early warning system for wheat blast.
Because of the challenging phenology of synthetic wheat and introductions from winter and facultative wheat zones, field condition evaluation of these germplasm is difficult and the greenhouse will help ease this hurdle. Additionally, several pathological experiments investigating the biology of wheat blast will now be able to be performed in the new greenhouse facility.
Supplementary activities at the greenhouse include disease screening and research into unlocking the genetics of host resistance. The installation of a diesel generator will keep the greenhouse running in case of power outages.

The Initiative aims to deliver agronomic gain at scale for millions of smallholder farming households in prioritized farming systems, with emphasis on supporting women and young farmers, to demonstrate measurable impact on food and nutrition security, income, water use, soil health and climate resilience.
Co-creation of agricultural solutions with farmers is integral to the Initiative through the engagement of modern tools, digital technologies, and behavioral science.
At the workshop, participants created a shared understanding of the Initiative’s goals for the region, laid groundwork for in-country planning and implementation, and increased visibility of the Initiative. Attendees agreed on the need to reevaluate beyond the boundaries of traditional agronomic practices and microeconomic challenges, considering policies at national and regional levels.

Combining expertise from across CGIAR research centers, private sector actors and government agriculture departments, the Initiative takes a data-based approach to offer demand-driven solutions. This was of particular appeal to Eyasu Elias, deputy minister at Ethiopia’s Ministry of Agriculture, who described the approach as “truly commendable” in comparison to conventional supply-driven approaches.
Elias, who was represented by a delegate at the event, highlighted Ethiopia’s current three priorities: managing acid soils; managing Vertisols so they utilize their natural productive potentials; and adopting practices that mitigate the formation of salt-affected soils.
“Attaining food security will be a tremendous challenge under current conditions,” explained Elias’ representative. “More than ever, we need innovative agronomic solutions that enhance nutrient use efficiencies; we need solutions that can be crafted from locally available alternatives. Collaborations that allow co-creation, co-design and participatory technology generation along these lines are appreciated from our end.”
“For several years, we’ve been building dense data sets with colleagues from the Indian Agricultural Research Council, which have allowed us to unravel complex farm realities through big data analytics, and to determine what agricultural management practices really matter in smallholder systems,” said Andrew McDonald ’94, M.S. ’98, Ph.D. ’03, associate professor of soil and crop sciences in the College of Agriculture and Life Sciences. “This process has confirmed that planting dates are the foundation for climate resilience and productivity outcomes in the dominant rice-wheat cropping systems in the eastern sector in India.”
The research was conducted through the Cereal Systems Initiative for South Asia (CSISA). CSISA, which is led by CIMMYT with the International Rice Research Institute and the International Food Policy Research Institute as research partners, was established in 2009 to promote durable change at scale in South Asia’s cereal-based cropping systems.
Researchers found that farmers in eastern India could increase yield by planting wheat earlier – avoiding heat stress as the crop matures – and quantified the potential gains in yields and farm revenues for the region. They also found that the intervention would not negatively impact rice productivity, a key consideration for farmers. Rice alternates with wheat on the cropping calendar, with many farmers growing rice in the wet season and wheat in the dry season.
The study also provides new recommendations for rice sowing dates and types of cultivars, to accommodate the earlier sowing of wheat.
“Farmers are not just managing single crops. They are managing a sequence of decisions,” said McDonald, who has a joint appointment in the Department of Global Development. “Taking a cropping systems approach and understanding how things cascade and interlink informs our research approach and is reflected in the recommendations that emerged from this analysis. Climate resilient wheat starts with rice.”
The research is the result of years of collaboration with international groups and government agencies in India, which have identified the Eastern Ganges Plain as the area with the most potential growth in production. The region will become essential, McDonald said, as the demand for wheat grows, and climate change makes production more difficult and unpredictable; just this year, record heat waves in March and April and food shortages caused by the war in Ukraine – both of which prompted India’s government to instate a ban on wheat exports – have highlighted the need for increased yields and more sustainable farming practices.
“In the bigger sense, this research is timely because the hazards of climate change aren’t just a hypothetical,” McDonald said. “Many of these areas are stress-prone environments, and extreme weather already constrains productivity. Identifying pragmatic strategies that help farmers navigate current extremes will establish a sound foundation for adapting to progressive climate change.”
Poverty is endemic in the Eastern Ganges Plain, and the region is dominated by small landholders, with varying practices and access to resources. The breadth and specificity of the data collected and analyzed in the study – including field and household survey data, satellite data, and dynamic crop simulations – allowed researchers to understand regional small farms’ challenges and the barriers to change.
“At the end of the day, none of this matters unless farmers opt in,” McDonald said. “There’s a spatial dimension and a household dimension to opportunity. If we can target approaches accordingly, then we hope to position farmers to make management changes that will benefit the entire food system.”
The study was co-authored with researchers from the Australian Department of Primary Industries and Regional Development, the International Rice Research Institute, the International Maize and Wheat Improvement Center, the International Food Policy Research Institute, the Indian Council of Agricultural Research and Bihar Agricultural University. The research was supported by the Bill and Melinda Gates Foundation and the U.S. Agency for International Development through grants to the Cereal Systems Initiative for South Asia, which is led by the International Maize and Wheat Improvement Center.

An international team of scientists has found that eco-friendly practices such as growing a range of crops, including legumes such as beans or pigeonpea, and adding plant residues or manure to soils can raise food crop yields in places such as rural Africa, where small-scale farmers cannot apply much nitrogen fertilizer.
Published in the science journal Nature Sustainability and examining data from 30 long-running field experiments involving staple crops (wheat, maize, oats, barley, sugar beet, or potato) in Europe and Africa, this major study is the first to compare farm practices that work with nature to increase yields and explore how they interact with fertilizer use and tillage.
“Agriculture is a leading cause of global environmental change but is also very vulnerable to that change,” said Chloe MacLaren, a plant ecologist at Rothamsted Research, UK, and lead author of the paper. “Using cutting-edge statistical methods to distill robust conclusions from divergent field experiment data, we found combinations of farming methods that boost harvests while reducing synthetic fertilizer overuse and other environmentally damaging practices.”
Recognizing that humanity must intensify production on current arable land to feed its rising numbers, the paper advances the concept of “ecological intensification,” meaning farming methods that enhance ecosystem services and complement or substitute for human-made inputs, like chemical fertilizer, to maintain or increase yields.
Boosting crop yields and food security for far-flung smallholders
The dataset included results from six long-term field experiments in southern Africa led by the International Maize and Wheat Improvement Center (CIMMYT). Africa’s farming systems receive on average only 17 kilograms of fertilizer per hectare, compared to more than 180 kilograms per hectare in Europe or close to 600 in China, according to Christian Thierfelder, a CIMMYT cropping systems agronomist and study co-author.
“In places where farmers’ access to fertilizer is limited, such as sub-Saharan Africa or the Central American Highlands, ecological intensification can complement scarce fertilizer resources to increase crop yields, boosting households’ incomes and food security,” Thierfelder explained. “We believe these practices act to increase the supply of nitrogen to crops, which explains their value in low-input agriculture.”
The CIMMYT long-term experiments were carried out under “climate-smart” conservation agriculture practices, which include reduced or no tillage, keeping some crop residues on the soil, and (again) growing a range of crops.
“These maize-based cropping systems showed considerable resilience against climate effects that increasingly threaten smallholders in the Global South,” Thierfelder added.
Benefits beyond yield
Besides boosting crop yields, ecological intensification can cut the environmental and economic costs of productive farming, according to MacLaren.
“Diversifying cropping with legumes can increase profits and decrease nitrogen pollution by reducing the fertilizer requirements of an entire crop rotation, while providing additional high-value food, such as beans,” MacLaren explained. “Crop diversity can also confer resilience to weather variability, increase biodiversity, and suppress weeds, crop pests and pathogens; it’s essential, if farmers are to improve maize production in places like Africa.”
Thierfelder cautioned that widespread adoption of ecological intensification will require strong support from policymakers and society, including establishing functional markets for legume seed and for marketing farmers’ produce, among other policy improvements.
“Dire and worsening global challenges — climate change, soil degradation and fertility declines, and scarcening fresh water — threaten the very survival of humanity,” said Thierfelder. “It is of utmost importance to renovate farming systems and bring us back into a safe operating space.”

CGIAR researchers are taking an innovative approach to analyzing crop and farming systems, by emphasizing nutritional yield. “This is an unusual perspective for an agronomist to apply to our work,” said Timothy Krupnik from the International Maize and Wheat Improvement Center (CIMMYT). “However, farmers in India recognize the critical need to produce more nutritious food that is environmentally sustainable without losing yield levels.”To meet this need, more than 25 researchers from CIMMYT and the Indian Council of Agricultural Research’s Central Soil Salinity Research Institute (ICAR-CSSRI) met from 25-27 May in Karnal, in India’s Haryana state, to plan a collaborative research program on nutrition-smart agriculture.
The program is part of Transforming Agrifood Systems in South Asia (TAFSSA), a CGIAR Regional Integrated Initiative aiming to propel evidence into impact through engagement with public and private partners across the farm production-to-consumption continuum. The Initiative will achieve productive, environmentally-sound agrifood systems that support equitable access to sustainable healthy diets in the world’s most poverty-dense region.
Through three days of workshops, attendees met with more than 200 men and women farmers. They developed a common understanding of the research objectives, designed research for multi-criteria analysis of crop and farming systems with an emphasis on nutritional yield, and developed a joint action plan for data collection and analysis.
To provide attendees with context for the research program, Temina Lalani-Shariff, CIMMYT Regional Director for South Asia, presented an overview of CGIAR activities in India and CGIAR Research Initiatives globally. HS Jat, Principal Scientist (Agronomy) from ICAR-CSSRI also presented some of the institute’s ongoing research and experiments that are examining the effects of different crop rotations on the production of nutritious foods. This included a visit to ICAR-CSSRI’s research trials later in the day.

From the ground up
To improve on the participatory design of research and to tailor the Initiative’s work to on-the-ground needs, the second day of the program was dedicated to visiting farmers in the states of Haryana and Punjab. There, researchers discussed the proposed research priorities and experimental design with the farmers. The design and priorities were later amended based on this feedback.

“This was an incredibly useful workshop for us,” said PC Sharma, Director of ICAR-CSSRI. “This represents a new way of thinking about how to approach crop rotations and production. Having the help of farmers and colleagues in the nutrition community to design our research means we can address multiple issues in one research program. This increases the value of our research and spreads the benefits wider.”
To conclude the workshops, groups presented on their field visits and selected crop rotations and management practices as part of agronomic trial design for nutrition-sensitive and environmentally efficient cropping systems, including consideration of implementation and data collection.
The project goal is to provide smallholder farmers with appropriate mechanization technologies that reduce drudgery during farm operations.
The objectives of the project are:
To promote small-scale mechanization through awareness and demand creation, and service provision of appropriate technologies
To create employment along the mechanization value chain.
The project sites are located in Amhara, Oromia, SNNP (Southern Nations, Nationalities and Peoples) and Tigray regions of Ethiopia.
The target beneficiaries of the project include smallholder farmers who use traditional methods of farming, the youth who can be employed in service provision activities along the mechanization value chain, service providers, and private sector companies involved in equipment manufacturing and importing.
Through the project, smallholder farmers access planting, harvesting, post-harvest processing (threshing and shelling), irrigation and transport services from service providers located in their communities. The project operates under the Africa-RISING program led by ILRI in Ethiopia.

MARPLE (Mobile And Real-time PLant disEase) diagnostics is a new innovative approach for fungal crop pathogen diagnostics developed by Diane Saunders’s team at the John Innes Centre.
MARPLE is the first operational system in the world using nanopore sequencing for rapid diagnostics and surveillance of complex fungal pathogens in situ. Generating results in 48 hours of field sampling, this new digital diagnostic strategy is leading revolutionary changes in plant disease diagnostics. Rapid strain level diagnostics are essential to quickly find new emergent strains and guide appropriate control measures.
Through this project, CIMMYT will:
Deploy and scale MARPLE to priority geographies and diseases as part of the Current and Emerging Threats to Crops Innovation Lab led by Penn State University / PlantVillage and funded by USAID’s Feed the Future.
Build national partner capacity for advanced disease diagnostics. We will focus geographically on Ethiopia, Kenya and Nepal for deployment of wheat stripe and stem rust diagnostics, with possible expansion to Bangladesh and Zambia (wheat blast).
Integrate this new in-country diagnostic capacity with recently developed disease forecasting models and early warning systems. Already functional for wheat stripe rust, the project plans to expand MARPLE to incorporate wheat stem rust and wheat blast.

The Harnessing Appropriate-Scale Farm Mechanization in Zimbabwe (HAFIZ) project aims to support investments by the government and by the private sector in appropriate-scale farm mechanization in Zimbabwe, particularly around Pfumvudza (a system of manual conservation agriculture), and transfer learnings to South Africa.
Overall, the project has the goal to improve access to mechanization and reduce labor drudgery whilst stimulating the adoption of climate-smart/sustainable intensification technologies. The project will improve the understanding of private sector companies involved in appropriate-scale farm mechanisation towards the local markets in which they operate.
Manufacturing knowledge of two-wheel and small four-wheel tractor operated implements for mechanized Pfumvudza will also increase and private sector companies will have increased access to information through the development and strengthening of regional and national communities of practitioners on appropriate-scale farm mechanization. Finally, the project will strengthen the capacity of the existing knowledge networks around appropriate-scale mechanisation in Zimbabwe, through the results that will be generated and through the regular multi-stakeholder roundtables that will be organised.
Objectives
Increasing and more spatially-targeted Government spending in appropriate-scale farm mechanisation in Zimbabwe (and South Africa)
Increasing sales of appropriate-scale farm mechanization equipment in Zimbabwe (and South Africa) thanks to more targeted marketing by private sector (both in terms of geographies and clients)
Local manufacturing and commercialization of two-wheel tractor operated basin diggers and bed planters in Zimbabwe.
In agriculture, good soil management is a pillar of productive systems that can sustainably produce sufficient and healthy food for the world’s growing population.
Soil properties, however, vary widely across geography. To understand the productive capacity of our soils, we need high-quality data. Soil Intelligence System (SIS) is an initiative to develop comprehensive soil information at scale under the Cereal Systems Initiative for South Asia (CSISA) project in India. SIS is led by the International Maize and Wheat Improvement Centre (CIMMYT) in collaboration with ISRIC – World Soil Information, International Food Policy Research Institute (IFPRI), and numerous local partners on the ground.
Funded by the Gates Foundation, the initiative launched in 2019 helps rationalize the costs of generating high-quality soils data while building accessible geo-spatial information systems based on advanced geo-statistics. SIS is currently operational in the States of Andhra Pradesh, Bihar and Odisha where the project partners collaborate with state government and state agricultural universities help produce robust soil health information.
Farmers are the primary beneficiaries of this initiative, as they get reliable soil health management recommendations to increase yields and profits sustainably while state partners, extension and agricultural development institutions and private sector benefit primarily by expanding their understanding for agricultural interventions.
Modern Soil Intelligence System Impact
CIMMYT’s SIS Project lead Balwinder Singh said, “The Soil Intelligence Systems initiative under CSISA is an important step towards the sustainable intensification of agriculture in South Asia. SIS has helped create comprehensive soil information – digital soil maps – for the states of Andhra Pradesh, Bihar and Odisha. The data generated through SIS is helping stakeholders to make precise agronomy decisions at scale that are sustainable.”
Since its launch in December 2019, a wider network and multi-institutional alliances have been built for soil health management and the application of big data in addressing agricultural challenges. In the three states the infrastructure and capacity of partners have been strengthened to leverage soil information for decision-making in agriculture by devising new soil health management recommendations. For example, in the state of Andhra Pradesh, based on SIS data and outreach, State Fertilizer and Micronutrient Policy (SFMP) recommendations were created. Similarly, soil health management zones have been established to strengthen the fertilizer distribution markets enabling farmers with access and informed choices.
“Soil Intelligence System delivers interoperable information services that are readily usable by emerging digital agricultural decision support systems in India”, noted Kempen Senior Soil Scientist at ISRIC.
The three-part infographic highlights the impact of SIS initiative in the select three States and emphasizes the importance of SIS in other parts of the country as well.
The Asia Regional Resilience to a Changing Climate (ARRCC) program is managed by the UK Met Office, supported by the World Bank and the UK’s Department for International Development (DFID). The four-year program, which started in 2018, aims to strengthen weather forecasting systems across Asia. The program will deliver new technologies and innovative approaches to help vulnerable communities use weather warnings and forecasts to better prepare for climate-related shocks.
Since 2019, as part of ARRCC, CIMMYT has been working with the Met Office and Cambridge University to pilot an early warning system to deliver wheat rust and blast disease predictions directly to farmers’ phones in Bangladesh and Nepal.
The system was first developed in Ethiopia. It uses weather information from the Met Office, the UK’s national meteorological service, along with field and mobile phone surveillance data and disease spread modeling from the University of Cambridge, to construct and deploy a near real-time early warning system.
Phase I: 12-Month Pilot Phase
Around 50,000 smallholder farmers are expected to receive improved disease warnings and appropriate management advisories in the first 12 months as part of a proof-of-concept modeling and pilot advisory extension phase focused on three critical diseases:
Wheat stripe rust in Nepal: extend and test the modelling framework developed in Ethiopia to smallholder farmers in Nepal as proof-of concept;
Wheat stem rust in Bangladesh and Nepal: while stem rust is currently not widely established in South Asia, models indicate that devastating incursion from neighboring regions is likely. This work will prepare for potential incursions of new rust strains in both countries;
Wheat blast in Bangladesh: this disease is now established in Bangladesh. This work will establish the feasibility of adapting the dispersal modelling framework to improve wheat blast predictability and deploy timely preventative management advisories to farmers.
Phase II: Scaling-out wheat rust early warning advisories, introducing wheat blast forecasting and refinement model refinement
Subject to funding approval the second year of the project will lead to validation of the wheat rust early warnings, in which researchers compare predictions with on-the-ground survey results, increasingly supplemented with farmer response on the usefulness of the warnings facilitated by national research and extension partners. Researchers shall continue to introduce and scale-out improved early warning systems for wheat blast. Concomitantly, increasing the reach of the advice to progressively larger numbers of farmers while refining the models in the light of results. We anticipate that with sufficient funding, Phase II activities could reach up to 300,000 more farmers in Nepal and Bangladesh.
Phase III: Demonstrating that climate services can increase farmers’ resilience to crop diseases
As experience is gained and more data is accumulated from validation and scaling-out, researchers will refine and improve the precision of model predictions. They will also place emphasis on efforts to train partners and operationalize efficient communication and advisory dissemination channels using information communication technologies (ICTs) for extension agents and smallholders. Experience from Ethiopia indicates that these activities are essential in achieving ongoing sustainability of early warning systems at scale. Where sufficient investment can be garnered to support the third phase of activities, it is expected that an additional 350,000 farmers will receive disease management warnings and advisories in Nepal and Bangladesh, totaling 1 million farmers over a three-year period.
Objectives
Review the feasibility of building resilience to wheat rust through meteorologically informed early warning systems.
Adapt and implement epidemiological forecasting protocols for wheat blast in South Asia.
Implement processes to institutionalize disease early warning systems in Nepal and Bangladesh.
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.
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 Data2 CSA) 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
