Atlas of Climate Adaptation in South Asian Agriculture (ACASA)

Written by mcallejas on . Posted in Uncategorized.

About ACASA

Increasing climatic risks make it imperative to identify spatial and temporal risks that are likely to impact agriculture. Adaptation options are thus needed to mitigate the negative impacts. Considering this, with support from the Bill & Melinda Gates Foundation (BMGF), the Borlaug Institute for South Asia (BISA) is working with national agriculture research systems in South Asia to develop the Atlas of Climate Adaptation in South Asian Agriculture (ACASA).

This comprehensive Atlas aims to provide granular-scale information for South Asian countries at the village scale by integrating various spatially explicit data sets together. It covers climate hazards, and the exposure of smallholder populations, farms, and crop and livestock enterprises to hazards. It will also look into the vulnerability of these populations to climatic risks, impacts on critical commodities in the region, and evidence of the effectiveness of different climate adaptation interventions.

The ACASA offers a unique set of tools that can facilitate improved investment targeting and priority setting, and support stakeholders’ decision-making and investments in agricultural technologies, climate information services, and policies. The intended beneficiaries of this Atlas include governments, insurance and agri-food industries, international and national donors, and adaptation-focused entities.

Accelerated Varietal Improvement and Seed Delivery of Legumes and Dryland Cereals in Africa (AVISA)

Written by mcallejas on . Posted in Uncategorized.

The Accelerated Varietal Improvement and Seed Delivery of Legumes and Dryland Cereals in Africa (AVISA) project increased demand-driven, gender equitable and timely access to quality seeds and inputs for small-scale producers by strengthening links between seed producers, farmers and grain aggregators, particularly women and young farmers. Partners included national agricultural research and extension systems (NARES), the Syngenta Foundation for Sustainable Agriculture (SFSA), the Center for Behavior Change Communication (CBCC) and the Tanzania Seed Traders Association (TASTA).

The project, which involved 188 NARES scientists from nine countries in East and Southern Africa (ESA) and West and Central Africa (WCA), tested different impact pathways to improve the scalability of dryland crop innovations. They identified 58 regional market segments for crops such as sorghum, pearl millet, finger millet, groundnut, chickpea and pigeonpea, of which 28 were prioritized for breeding pipelines. Target product profiles were consolidated and priority traits were addressed through a crop health/pathology network. Breeding programs were implemented through shared pipelines, regional trials were conducted and 2,461 farmers participated in tricots.

Efforts included the formation of a cowpea WCA working group, the identification of 26 common bean market segments in East Africa, and the implementation of awareness and demand generation activities using a variety of promotional methods. Data-driven decisions were prioritized, resulting in the creation of breeding informatics teams, quality assurance/control pipelines, and digitization templates.

The project also established governance structures and steering committees for the two target regions in sub-Saharan Africa, as well as operational committees and elected representatives to ensure the functioning and sustainability of the CGIAR-NARES dryland crops network.

In addition, the project targets the Sustainable Development Goals: SDG 2 – Zero Hunger; SDG 13 – Climate Action; SGD 17 – Partnerships for the Goals.

Country moving forward from wheat importer to self-sufficiency

Written by mcallejas on . Posted in Features.

Wheat is critical to millions of households in Pakistan as it serves a dual role as a foundational part of nutritional security and as an important part of the country’s economy. Pakistan’s goal to achieve self-sufficiency in wheat production is more attainable with the release of 31 wheat varieties since 2021.

These new seeds will help the country’s 9 million hectares of cultivated wheat fields become more productive, climate resilient, and disease resistant—a welcome development in a region where climate change scenarios threaten sustained wheat production.

The varieties, a selection of 30 bread wheat and 1 durum wheat, 26 of which developed from wheat germplasm provided by the International Maize and Wheat Improvement Center (CIMMYT) were selected after rigorous testing of international nurseries and field trials by partners across Pakistan. During this period, three bread wheat varieties were also developed from local breeding programs and two varieties (one each of durum and bread wheat) were also developed from the germplasm provided by the ICARDA. These efforts are moving Pakistan closer to its goal of improving food and nutrition security through wheat production, as outlined in the Pakistan Vision 2025 and Vision for Agriculture 2030.

Over multiple years and locations, the new varieties have exhibited a yield potential of 5-20% higher than current popular varieties for their respective regions and also feature excellent grain quality and attainable yields of over seven tons per hectare.

The new crop of varieties exhibit impressive resistance to leaf and yellow rusts, compatibility with wheat-rice and wheat-cotton farming systems, and resilience to stressors such as drought and heat.

Battling malnutrition

Malnutrition is rampant in Pakistan and the release of biofortified wheat varieties with higher zinc content will help mitigate its deleterious effects, especially among children and women. Akbar-2019, a biofortified variety released in 2019, is now cultivated on nearly 3.25 million hectares. Farmers like Akbar-2019 because of its 8-10% higher yields, rust resistance, and consumers report its good chapati (an unleavened flatbread) quality.

“It is gratifying seeing these new varieties resulting from collaborative projects between Pakistani wheat breeding programs and CIMMYT along with funding support from various donors (USAID, Bill & Melinda Gates Foundation, HarvestPlus, and FCDO) and the government of Pakistan,” said Ravi Singh, wheat expert and senior advisor.

Closing the yield gap between research fields and smallholder fields

Releasing a new variety is only the first step in changing the course of Pakistan’s wheat crop. The next step is delivering these new, quality seeds to markets quickly so farmers can realize the benefits as soon as possible.

Increasing evidence suggests the public sector cannot disseminate enough seeds alone; new policies must create an attractive environment for private sector partners and entrepreneurs.

“Pakistan has developed a fast-track seed multiplication program which engages both public and private sectors so the new varieties can be provided to seed companies for multiplication and provided to farmers in the shortest time,” said Javed Ahmad, Wheat Research Institute chief scientist.

Strengthening and diversifying seed production of newly released varieties can be done by decentralizing seed marketing and distribution systems and engaging both public and private sector actors. Marketing and training efforts need to be improved for women, who are mostly responsible for household level seed production and seed care.

A concerted effort to disseminate the improved seed is required, along with implementing conservation agriculture based sustainable intensification, to help Pakistan’s journey to self-sufficiency in wheat production.

CIMMYT and BWMRI host international training program on surveillance and management strategies for wheat blast

Written by Julian Bañuelos-Uribe on . Posted in News.

The devastating disease wheat blast is a threat to crop production in many South Asian countries. In Bangladesh, it was first identified in seven southern and southwestern districts in 2016, and later spread to 27 others causing significant damage. The International Maize and Wheat Improvement Center (CIMMYT) is working with the Bangladesh Wheat and Maize Research Institute (BWMRI) and other national partners to conduct research and extension activities to mitigate the ongoing threat.

From March 1-10, 2023, a group of 46 wheat researchers, government extension agents, and policy makers from ten countries — Bangladesh, Brazil, China, Ethiopia, India, Japan, Mexico, Nepal, Sweden, and Zambia — gathered in Jashore, Bangladesh to learn about and exchange experiences regarding various wheat diseases, particularly wheat blast. Following the COVID-19 pandemic, this was the first in-person international wheat blast training held in Bangladesh. It focused on the practical application of key and tricky elements of disease surveillance and management strategies, such as resistance breeding and integrated disease management.

“This is an excellent training program,” said Shaikh Mohammad Bokhtiar, executive chairman of the Bangladesh Agriculture Research Council (BARC), during the opening session.  “Participants will learn how to reduce the severity of the blast disease, develop and expand blast resistant varieties to farmers, increase production, and reduce imports.”

This sentiment was echoed by Golam Faruq, director general of BWMRI. “This program helps in the identification of blast-resistant lines from across the globe,” he said. “From this training, participants will learn to manage the devastating blast disease in their own countries and include these learnings into their national programs.”

Hands-on training

The training was divided into three sections: lectures by national and international scientists; laboratory and field experiment visits; and trips to farmers’ fields. Through the lecture series, participants learned about a variety of topics including disease identification, molecular detection, host-pathogen interaction, epidemiology and integrated disease management.

Hands-on activities were linked to working on the Precision Phenotyping Platform (PPP), which involves the characterization of more than 4,000 wheat germplasm and releasing several resistant varieties in countries vulnerable to wheat blast. Participants practiced taking heading notes, identifying field disease symptoms, tagging, and scoring disease. They conducted disease surveillance in farmers’ fields in Meherpur and Faridpur districts — both of which are extremely prone to wheat blast — observing the disease, collecting samples and GPS coordinates, and completing surveillance forms.

Participants learned how to use cutting-edge technology to recognize blast lesions in leaves using field microscopes. They went to a pre-installed spore trapping system in a farmer’s field to learn about the equipment and steps for collecting spore samples, observing them under a compound microscope, and counting spores. They also visited the certified seed production fields of Shawdesh Seed, a local company which has played an important role in promoting wheat blast resistant varieties BARI Gom 33 and BWMRI Gom 3 regionally, and Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU) in Gazipur to see current wheat blast research in action.

Blast-resistance in Bangladesh

“I am so happy to see the excellent infrastructure and work ethics of staff that has made possible good science and impactful research come out of the PPP,” said Aakash Chawade, associate professor in Plant Breeding at the Swedish University of Agricultural Sciences. “Rapid development of blast-resistant varieties and their dissemination will help Bangladesh mitigate the effects of wheat blast, not only inside the country but by supporting neighboring ones as well.”

“Besides the biotic and abiotic challenges faced in wheat production, climate change and the Russia-Ukraine crisis are further creating limitations to wheat production and marketing,” said Pawan Kumar Singh, head of Wheat Pathology at CIMMYT and lead organizer of the training. “Due to the development of blast-resistant wheat varieties and its commercial production under integrated disease management practices, the domestic production of wheat in Bangladesh has increased and there is increased interest from farmers in wheat.”

Dave Hodson, a principal scientist at CIMMYT and one of the training’s resource speakers, added: “This is a remarkable success that researchers developed two blast resistant varieties in Bangladesh urgently. It was only achievable because of the correct measures taken by the researchers and support of Government policies.”

However, there are still some barriers to widespread adoption of these varieties. As such, in parallel to other activities, a team from Bangladesh Agricultural University (BAU) joined the field trip to meet local farmers and conduct research into the socio-economic factors influencing the adoption and scaling of relevant wheat varieties.

Wheat output in Africa and South Asia will suffer severely from climate change by 2050, modelling study shows

Written by Julian Bañuelos-Uribe on . Posted in Publications.

Leading crop simulation models used by a global team of agricultural scientists to simulate wheat production up to 2050 showed large wheat yield reductions due to climate change for Africa and South Asia, where food security is already a problem.

The model predicted average declines in wheat yields of 15% in African countries and 16% in South Asian countries by mid-century, as described in the 2021 paper “Climate impact and adaptation to heat and drought stress of regional and global wheat production,” published in the science journal Environmental Research Letters. Climate change will lower global wheat production by 1.9% by mid-century, with the most negative impacts occurring in Africa and South Asia, according to the research.

“Studies have already shown that wheat yields fell by 5.5% during 1980-2010, due to rising global temperatures,” said Diego N.L. Pequeno, wheat crop modeler at the International Maize and Wheat Improvement Center (CIMMYT) and lead author of the paper. “We chose several models to simulate climate change impacts and also simulated wheat varieties that featured increased heat tolerance, early vigor against late season drought, and late flowering to ensure normal biomass accumulation. Finally, we simulated use of additional nitrogen fertilizer to maximize the expression of these adaptive traits.”

The wheat simulation models employed — CROPSIM-CERES, CROPSIM, and Nwheat within the Decision Support System for Agrotechnology Transfer, DSSAT v.4.6 — have been widely used to study diverse cropping systems around the world, according to Pequeno.

“The DSSAT models simulated the elevated CO2 stimulus on wheat growth, when N is not limiting,” he said. “Our study is the first to include combined genetic traits for early vigor, heat tolerance, and late flowering in the wheat simulation.”

Several factors, including temperature, water deficit, and water access, have been identified as major causes in recent wheat yield variability worldwide. The DSSAT wheat models simulate the impact of temperature, including heat stress, water balance, drought stress, or nitrogen leaching from heavy rainfall.

“Generally, small and low-volume wheat producers suffered large negative impacts due to future climate changes, indicating that less developed countries may be the most affected,” Pequeno added.

Climate change at high latitudes (France, Germany, and northern China, all large wheat-producing countries/region) positively impacted wheat grain yield, as warming temperatures benefit wheat growth through an extended early spring growing season. But warmer temperatures and insufficient rainfall by mid-century, as projected at the same latitude in Russia and the northwestern United States, will reduce rainfed wheat yields — a finding that contradicts outcomes of some previous studies.

At lower latitudes that are close to the tropics, already warm, and experiencing insufficient rainfall for food crops and therefore depending on irrigation (North India, Pakistan, Bangladesh), rising heat will damage wheat crops and seriously reduce yields. China, the largest wheat producer in the world, is projected to have mixed impacts from climate change but, at a nation-wide scale, the study showed a 1.2% increase in wheat yields.

“Our results showed that the adaptive traits could help alleviate climate change impacts on wheat, but responses would vary widely, depending on the growing environment and management practices used,” according to Pequeno. This implies that wheat breeding for traits associated with climate resilience is a promising climate change adaptation option, but its effect will vary among regions. Its positive impact could be limited by agronomical aspects, particularly under rainfed and low soil N conditions, where water and nitrogen stress limit the benefits from improved cultivars.

Extreme weather events could also become more frequent. Those were possibly underestimated in this study, as projections of heat damage effects considered only changes in daily absolute temperatures but not possible changes in the frequency of occurrence. Another limitation is that most crop models lack functions for simulating excess water (e.g., flooding), an important cause of global wheat yield variability.

This study was supported by the CGIAR Research Program on Wheat agri-food systems (CRP WHEAT; 2012-2021), the CGIAR Platform for Big Data in Agriculture, the International Wheat Yield Partnership (IWYP115 Project), the Bill & Melinda Gates Foundation, the World Bank, the Mexican government through the Sustainable Modernization of Traditional Agriculture (MasAgro) project, and the International Treaty of Plant Genetic Resources for Food and Agriculture and its Benefit-sharing Fund for co-funding the project, with financial support from the European Union.

New generation of farmers lead the way in making farming more productive and profitable

Written by Nima Chodon on . Posted in Features.

In the Indo-Gangetic Plains of northern India, nearly 70% of the population is involved in agriculture and extension services. Despite the abundantly fertile soil and farmers’ resilience, the adoption of agricultural innovations and productivity in the region has been slow.

This slow progress is often attributed to comparatively low levels of agricultural mechanization in the region and small land holdings of individual farmers, which often makes them risk averse to new technologies. However, times are changing.

Through the Cereal Systems Initiative for South Asia (CSISA) project, researchers from the International Maize and Wheat Improvement Center (CIMMYT), working closely with the local Krishi Vigyan Kendra (KVK) and partners, have led the transition from traditional farming to sustainable intensification agricultural practices in the region, helping the region slowly but steadily realize its full potential. Over the years, working extensively with progressive farmers, CSISA scientists have helped optimize the cost of inputs and increase productivity through new technology adoption and capacity building for these farmers.

Krishnamohan Pathak, a farmer in his early sixties from the village of Patkhaoli, first learned about conservation agriculture practices when he attended a field event in Nonkhar village in Deoria district, Uttar Pradesh. CSISA researchers invited farmers from Nonkhar and neighbouring villages to attend a field day event, an exposure activity, on zero tillage wheat and direct seeded rice (DSR) technologies. Zero tillage allows farmers to plant directly without plowing or preparing the soil, minimizing soil movement. Pathak was one of the farmers who got to see first-hand the advantages of these sustainable agricultural practices.

Seeing merit in these practices, Pathak continued to engage with CSISA scientists and in 2013-2014, adopted zero tillage, and directly seeded rice in his family-owned fields.

“The CSISA field team encouraged me to buy a rice planter which has helped manage paddy transplantation on time, and wheat after that through zero till,” Pathak said.

Pathak later participated in other agri-technology events and CSISA field trial activities. In 2018, he joined other progressive farmers from the region who attended a training at ISARC (IRRI South Asia Regional Centre) in Varanasi, Uttar Pradesh on direct seeded rice, organized by CSISA researchers to build capacity and raise awareness of the conservation agriculture method.

The next generation leads the way

Today, Pathak is one of the key influential farming members in the region. He has now, however, passed the baton to his 37-year-old son Gangesh Pathak. “I have occupied myself with other local leadership activities after my son has been active in the fields. I am not so skilled at using these machines, their maintenance and their services. The younger generation seems much better at adapting,” he said.

Gangesh has been involved actively in farming ever since he finished his graduation, trying to make it lucrative. He has enjoyed recent success growing wheat and rice through new technology and practices. Standing in the fields recently harvested with the new improved wheat variety DBW 187, grown through early sowing – a method which goes against the traditional practice of planting after November – and zero tillage, he is happy with his 5.5 ton per hectare yield.

He spoke enthusiastically about the farming machinery he has procured to reduce drudgery in his farms and the hiring services provided to smallholder farmers in the region. After his father bought the transplanter in 2014, the family added larger machines such as the Happy Seeder, Super Seeder, Laser Land Leveller, Straw Reaper, and Direct Seeded Rice machine.

According to Gangesh, this has been possible thanks to the support from the local agriculture authorities and guidance from the CSISA team, who told his father about the various schemes offered by the central and state government to support farmers to adopt more productive and sustainable agricultural technologies.

Ajay Kumar Pundir, CIMMYT agronomist, based in Uttar Pradesh and leading CSISA’s efforts, stressed the importance of access to agricultural mechanization and support.

“Our job just does not end at informing and training farmers about better-bet agricultural practices. Along with other public and private stakeholders, we must support and ensure their availability and access – machines, quality seeds, timely information – for farmers to adopt it,” he said.

Custom hiring center help scale mechanization

With so much farm machinery, the Pathaks soon began extending hiring services. Custom hiring is a promising enterprise opportunity for farmers as they can use the machinery on their farms and earn extra income by extending services to other farmers at a reasonable cost, which helps cover diesel and maintenance costs. Gangesh made about 2.5 lakhs (USD $3,033.76) in profit during the 2022-2023 Rabi (winter crops) through hay machine hiring services, where around 250 farmers used these services.

Once the word spread, demand for hiring services by smallholder farmers, challenged by scarce labor for sowing and harvesting, started growing. Gangesh was encouraged by the good profits and was keen to share the benefits of such hiring services to as many farmers as possible, and he helped establish a Farmer Producer Organization (FPO) with his father, Krishnamohan. FPO is a group made up of farmer-producers who are entitled to a host of benefits, including quality seeds, technical support, market access, under the Department of Agriculture and Farmers Welfare (DA&FW).

The FPO, started by the Pathaks in 2020, with 75 members (farmers) initially, currently boasts of around 300 farmers. Almost all FPO members have availed the custom hiring services for all farming purposes and various crops. Farmers, “particularly smallholders who cannot afford to purchase these machines for less than a few acres of land, are happy with the custom hiring services. It helps reduce their input cost by almost 50% along with other FPO member benefits,” Gangesh said.

Community-based technology demonstrations by CSISA and KVK and partners are ongoing to scale-out proven technologies and practices like early wheat sowing, zero tillage, and direct seeded rice. Gangesh is hopeful that farmers in the region, despite the emerging climate crisis concerns – already being felt in the region – can produce more and improve their income. He reckons that diversifying between rice-wheat cropping systems, mechanizing and system optimization through better advisories, and improved access to technologies as recommended by agronomists, will help farmers stay ahead of the curve.

On-farm-Maize Select

Written by Leslie Domínguez on . Posted in Uncategorized.

The On-farm-Maize Select project will pilot a new genomics-driven selection method based on on-farm performance of Stage 1 maize breeding materials that is expected to deliver increased rates of genetic gain to the farmers through:

  • More accurate selection for the conditions of small-scale producers in Sub-Saharan Africa (SSA), especially women and the poorest farmers, who often apply fewer inputs.
  • Improved sampling of the diversity of on-farm conditions across the entire target population of environments (TPE).
  • Improved understanding of the diversity of socio-economic factors, agronomic management (especially by women), and environmental on-farm conditions across the TPE.
  • Genomic-assisted rapid recycling of parents (population improvement) to reduce breeding cycle time.
  • Improved social inclusion in breeding processes, leading to greater gender responsiveness and wider appeal of breeding outputs.

The hypothesis is that generating genomic estimated breeding values (GEBVs) based on on-farm phenotyping will lead both to increased selection accuracy for performance under farmer management, including challenging conditions that women and the poorest farmers face, and enable rapid cycling of parents by reducing the number of years of testing before new crosses are made. This hypothesis will be initially tested by estimating expected genetic gain on-station and on-farm based on the genetic correlation between on-station and gender-disaggregated on-farm performance of the same set of genotypes, as well as the repeatability of selection on-station versus on-farm. The value of on-farm versus on-station testing for estimating GEBVs for parent selection and early-stage advancement will be confirmed in two selected CIMMYT maize breeding pipelines (one each in eastern and southern Africa – EA-PP1 and SA-PP1) by comparing the performance on-farm of a sample of Stage 1 breeding lines from the second cycle of on-farm vs on-station selection. The efficacy and costs of undertaking on-farm genomic selection versus on-station selection at Stage 1 of the two selected breeding pipelines will also be evaluated.

Key Outputs

  • The genetic correlation between, and accuracy of estimation of, on-farm and on-station breeding values will be measured in terms of ability to predict performance under farmer management. This will enable comparison of the relative efficiency of direct selection on-farm versus indirect selection on-station. We expect that increased on-farm genetic gains will be achieved if the genetic correlation between on-farm and on-station performance is 0.8 or less.
  • Elite breeding populations improved for on-farm performance will be generated, and products extracted from them will be compared on-farm with those selected the same founder populations using conventional on-station selection (comparison of the products of the pipelines will not be possible until the second project phase, if approved).
  • Separate GEBVs generated for lines under the management of male and female farmers, with genetic correlations estimated to ensure that performance on female-managed farms is adequately weighted in selection indices.
  • Genomic-assisted on-farm sparse testing network, experimental design and capacity developed.
  • Improved representativeness of results due to enhanced gender and social inclusion approaches in the on-farm trial design.

Expected Outcomes

  • Greater rates of genetic gain delivered on-farm through more extensive sampling of TPEs
  • Improved accuracy of selection based on performance in farmers’ fields in the TPE.
  • Incorporation of farmer-preferred traits in selection decisions supports faster replacement of older hybrids with newer products.

1000FARMS

Written by Leslie Domínguez on . Posted in Uncategorized.

1000FARMS is an institutional platform of NARES/CGIAR breeding networks whose purpose is to magnify their effectiveness and impact by enabling them to generate sufficient on-farm data and product insights on late-stage maize breeding selection candidates and new releases to ensure they will be high-performing in the hands of farmers, are farmer-preferred and climate-adapted, and can be recommended for scaling by the seed system. The platform achieves this by integrating three primary components:

  1. tricot, or triadic comparison of technology options, a research methodology that helps farmers to identify the most suitable technologies for the local conditions of their farm, engaging them in the testing or validation of new crop varieties and other promising technologies.
  2. ClimMob, a digital public software package developed by the Alliance of Bioversity-CIAT that allows farmers and field agents to record crowdsourced data, such as variety preferences, notes on performance, images, and gender/socio-economic data.
  3. An on-farm trial (OFT) community of practice embedded in the NARES/CGIAR Breeding Networks in Africa.

These tools and methodologies already exist and have been well-tested; the innovation of 1000FARMS is to put all three components together to accelerate the uptake of the OFT approach across CGIAR and NARES breeding networks.

Objectives:

  1. Expand and improve OFT tools to enable streamlined workflows and extract more insights from OFT data.
  2. Implement appropriately scaled on-farm testing programs in partnership with at least 20 NARES/CG crop breeding networks.

CGIAR Initiative: Crops to End Hunger (CtEH)

Written by Sarah McLaughlin on . Posted in Uncategorized.

Agriculture offers major solutions to several global challenges – most notably the tightly interlinked challenges of meeting Sustainable Development Goals (SDGs) on hunger (SDG2), extreme poverty (SDG1), and climate change (SDG13). CGIAR, in concert with a wide network of partners, has a vital role to play in transforming agri-food and land systems in the face of the climate emergency – ultimately benefiting low-income producers and consumers who are most at risk.

What is Crops to End Hunger?

Crops to End Hunger (CtEH) is a CGIAR initiative to accelerate and modernize the development, delivery and widescale use of a steady stream of new crop varieties. These new varieties are developed to meet the food, nutrition and income needs of producers and consumers, respond to market demand and provide resilience to pests, diseases and new environmental challenges arising from climate change.

CGIAR’s plant breeding program has made major contributions to global food security since the mid 1960s, but there is evidence that the rate of adoption of new varieties has slowed. CtEH will support the acceleration of breeding cycles and application of modern breeding methods needed for both productivity gains and climate change adaptation. Farmers need varieties bred in and for the current climate, but are generally using varieties selected 20-30 years ago. In addition, many new varieties are insufficiently improved to induce farmers to adopt them. Prioritization of crops by specific geographies is based on projected benefits to poverty reduction and nutrition, and is an integral dimension of the modernization effort. Using market research, crop breeders gain greater awareness of the traits preferred by men and women farmers, consumers and others along the value chain, integrating them into “product profiles” that guide breeding. Delivery of varieties is done through integrated partnerships and linkages to seed systems in-country, in which national regulatory agencies take responsibility for the release of improved seeds, while public agencies, community organizations and private seed companies undertake multiplication, distribution and promotion to reach farmers’ fields.

In 2017-18, a multi-Funder group, including the United States Agency for International Development (USAID), the Bill & Melinda Gates Foundation (BMGF), the UK Foreign, Commonwealth and Development Office (FCDO), the German Federal Ministry for Economic Cooperation and Development (BMZ) and the Australian Centre for International Agricultural Research (ACIAR), agreed to launch a modernization program for public plant breeding in lower-income countries. The CtEH initiative will invigorate breeding for the staple crops most important to smallholder farmers and poor consumers.

How does it work?

CtEH supports focused, science-based, well-resourced and long-term CGIAR Programs and investments in modern plant breeding on priority crops, which build on:

  1. CGIAR’s demonstrated impact on food security and poverty reduction through plant breeding;
  2. CGIAR’s comparative advantages in global public goods research on crop breeding and genetics;
  3. CGIAR’s central role and responsibility for the conservation and characterization of the world’s crop biodiversity, which is held in trust by CGIAR Research Centers for the world community.

This initiative aims to accelerate a transition in CGIAR crop breeding to address very different challenges from those faced in the Green Revolution. Twenty CGIAR crops, including cereals, legumes and root crops, have been chosen for this breeding initiative.

One part of this challenge is for breeding to modernize in terms of its objectives beyond pure yield gain – to address the expanding demand for improved varieties to meet biotic and abiotic stresses, such as climate change and environmental degradation, and to include a wider set of nutritional and market traits, as well as traits relevant to both end-users and value chains, which would increase the adoption rate of newly-bred varieties.

The first step towards modernization of breeding programs is to identify the gaps – the areas that need to be addressed or improved. The Breeding Program Assessment Tool (BPAT) has been developed for this purpose. The deployment of BPAT has been administered by the University of Queensland and has now been used to assess the breeding programs across CGIAR Research Centers. Examples of gaps include cross-CGIAR data management tools, access to low-cost genotyping, and sharing high-quality technical advice across programs and with partners.

What will result?

This process of improvement and modernization of CGIAR breeding programs will provide multiple benefits:

  1. For a given level of investment it is anticipated that each breeding program will achieve increased rates of genetic gain and scale of impact – through adoption of farmer-preferred, market-demanded, climate-resilient varieties.
  2. There will be further opportunity to integrate and support allied CGIAR crop programs, and to apply best practices across CGIAR Research Centers.
  3. A stronger partnership and closer cooperation with national breeding programs, including national research institutes, universities and small and medium-sized enterprises in the private sector in low-income countries, as well as multilateral seed companies and advanced research institutes.
  4. Adopting standardized ways of reporting needs, opportunities and progress will provide Funders with a transparent view of where and how they are getting high rates of return for their investment.

With this new initiative, CGIAR will enhance its contributions to the Sustainable Development Goals towards 2030 through high-priority staple crops tailored for the specific needs of targeted regions and their populations.

Representatives from Australian Centre for International Agricultural Research (ACIAR) and Bangladesh Agricultural Research Council (BARC) paid a visit to Bangladesh to see the valuable work of the Precision Phenotyping Platform (PPP).

PPP was established in response to the devastating wheat blast disease, which was first reported in the country in 2016.

Technical and financial support from the International Maize and Wheat Improvement Center (CIMMYT), the Australian Commission for International Agricultural Research and the Australian Centre for International Agricultural Research, along with other funders, has contributed to the effort to combat the disease.

This is achieved by generating precise data for wheat blast resistance in germplasm in Bangladesh, as well as other wheat growing countries. This PPP has been used to screen elite lines and genetic resources from various countries.

On February 16 and 17, 2023, two groups of national and international delegations visited the BWMRI-CIMMYT collaborative research platform PPP at the BWMRI regional station in Jashore, Bangladesh.

The first group was made up of representatives from both the Australian Commission for International Agricultural Research and the Australian Centre for International Agricultural Research. This included seven commissioners under the direction of Fiona Simson, along with ACIAR senior officials from Australia and India.

The other group was from BARC, which was led by Executive Chairman Shaikh Mohammad Bokhtiar, along with Golam Faruq, Director General of BWMRI, and Andrew Sharpe, Bangabandhu Research Chair, Global Institute of Food Security (GIFS), University of Saskatchewan in Canada.

Both delegations were welcomed by Muhammad Rezaul Kabir, the Senior Wheat Breeder at BWMRI. Kabir gave a brief presentation about the platform and other wheat blast collaborative research programs in the seminar room.

The delegations then went to the PPP field, where BWMRI researchers Kabir and Robiul Islam, as well as CIMMYT researcher Md. Harun-Or-Rashid, explained further information about the BWMRI-CIMMYT collaborative research. Both commissioners and delegates appreciated seeing the work being conducted in person by the national and international collaborations of BWMRI and CIMMYT on wheat blast research.

“It is important, innovative work, that is affecting not only Bangladesh but many countries around the world that are now starting to be concerned about the impacts of wheat blast,” commissioner Simson said. “This study is very important for Australia and we are pleased to be contributing to it.”

Lindsay Falvey, another commissioner, added, “This is a wonderful experiment, using high-level science and technologies to combat wheat blast in Bangladesh. The experiment is well-planned. Overall, it is an excellent platform.”

ACIAR delegate Eric Huttner added to the praise for the project. “The platform is performing extremely well for the purpose of evaluating lines, resistance to the disease and that’s very useful for Bangladesh and rest of the world,” he said. “This is a gift that Bangladesh is giving to the neighboring countries to protect wheat.”

The delegates pledged to share their expert advice with the Minister of Foreign Affairs in Bangladesh in order to increase investments and improve facilities for agricultural research programs in the country.

“This is an excellent work,” Executive Chairman of BARC, Bokhtiar said. “We can get more information from screening activities by using bioinformatics tools and training people through the BARC-GIFS program.”

Pawan Kumar Singh, Head of Wheat Pathology at CIMMYT-Mexico and Project Leader, coordinated the visits virtually and expressed his thanks to the delegations for their visit to the platform. This PPP, within a short span of few years, has been highly impactful, characterizing more than 15,000 entries and releasing several resistant varieties in countries vulnerable to wheat blast.

Wheat Disease Early Warning Advisory System (DEWAS)

Written by Sarah McLaughlin on . Posted in Uncategorized.

The Wheat Disease Early Warning Advisory System (Wheat DEWAS) project is bringing new analytic and knowledge systems capacity to one of the world’s largest and most advanced crop pathogen surveillance systems. With Wheat DEWAS, researchers are building an open and scalable system capable of preventing disease outbreaks from novel pathogen strains that threaten wheat productivity in food vulnerable areas of East Africa and South Asia.

The system builds from capabilities developed previously by multi-institutional research teams funded through long-term investments in rust pathogen surveillance, modelling, and diagnostics. Once fully operationalized, the project aims to provide near-real-time, model-based risk forecasts for governments. The result: accurate, timely and actionable advice for farmers to respond proactively to migrating wheat diseases.

The Challenge

Farmers growing wheat face pathogen pressures from a range of sources. Two of the most damaging are the fungal diseases known as rust and blast. Rust is a chronic issue for farmers in all parts of the world. A study in 2015 estimated that the three rust diseases — stem, stripe and leaf — destroyed more than 15 million tons of wheat at a cost of nearly $3 billion worldwide. Wheat blast is an increasing threat to wheat production and has been detected in both Bangladesh and Zambia. Each of these diseases can destroy entire harvests without warning, wiping out critical income and food security for resource-poor farmers in vulnerable areas.

The Response

Weather forecasts and early-warning alerts are modern technologies that people rely on for actionable information in the case of severe weather. Now imagine a system that lets farmers know in advance when dangerous conditions will threaten their crop in the field. Wheat DEWAS aims to do just that through a scalable, integrated, and sustainable global surveillance and monitoring system for wheat.

Wheat DEWAS brings together research expertise from 23 research and academic organizations from sub-Saharan Africa, South Asia, Europe, the United States and Mexico.

Together, the researchers are focused on six interlinked work packages:

The formation of regional crop improvement networks took center stage at a meeting held in January 2023 in Accra, Ghana. The meeting convened more than 200 scientists and stakeholders in dryland crops value chains from 28 countries from Africa and across the globe to co-design a network approach.

The meeting followed a series of consultative visits and discussions between three CGIAR research centers — the International Maize and Wheat Improvement Center (CIMMYT), Alliance of Bioversity International and CIAT, and the International Institute of Tropical Agriculture (IITA) — African National Agricultural Research Institutes (NARIs), and other common-visioned partners during 2021 and 2022. These earlier discussions gathered insights, brainstormed, and co-designed approaches to empower national programs to deliver impact through their crop improvement programs.

“The idea is to add value to the existing capacities in National Agricultural Research and Extension Services, through networks where the partners agree on the goals and resources needed to achieve desired outcomes. So, it’s really a collaborative model,” said Harish Gandhi, breeding lead for dryland legumes and cereals at CIMMYT. He added that the teams have been learning from and aiming to add value to existing models such as the Pan-Africa Bean Research Alliance (PABRA), USAID Innovation Labs, and Innovation and plant breeding in West Africa (IAVAO).

Paradigm shift for African National Agricultural Research Institutes

Making the opening remarks, Ghana Council for Scientific and Industrial Research (CSIR) Director General, Paul Bosu said that at the very least, African countries should aim to feed themselves and transition from net importers to net exporters of food. “Dryland legumes and cereals, especially millet and sorghum, are very well adapted to the continent and offer great opportunity towards achieving food security”, said Bosu. He applauded the Bill & Melinda Gates Foundation and other partners for investing in research on these crops.

Representing West and Central African Council for Agricultural Research and Development (CORAF), Ousmane Ndoye noted that research in dryland legumes and cereals is a valid and needed action amidst the COVID-19 pandemic and civil unrest in different parts of the world. He added that the first and crucial step to increasing food production especially in sub-Saharan Africa is the availability of sufficient quantities of seed.

Director General of Uganda’s National Agriculture Research Organization (NARO), Ambrose Agona observed that a paradigm shift should occur for desired transformation in agriculture. He noted that African governments ought to commit adequate budgets to agriculture and that seed funding should serve to complement and amplify existing national budgets for sustainability.

He commended efforts to consult NARIs in Africa and noted that the quality of ideas exchanged at the meeting strengthen the work. “The NARIs feel happier when they are consulted from the very beginning and contribute to joint planning unlike in some cases where the NARIs in Africa are only called upon to make budgets and are excluded from co-designing projects”, said Agona.

Challenge to deliver effectively

During his remarks at the meeting, CIMMYT Director General Bram Govaerts noted that the focus legume and cereal crops are key to transforming and driving diversification of food systems in Africa. “It is therefore an honor and a privilege to work together with partners to improve cereal and legume systems. We will put forward our experience in breeding and commit to innovative systems approaches towards achieving impact and leverage what we are already good at, to become even better,” said Govaerts.

Referencing his visit with the United States Special Envoy for Global Food Security Cary Fowler to Southern Africa in January 2023, Govaerts narrated witnessing firsthand a food, energy and fertilizer crisis impacting Zambian and Malawian farmers. He challenged the meeting participants to envision the future impact they would like to see their breeding programs have as they design and strategize at the meeting. He pointed out that farmers are more interested in the qualities and characteristics of varieties released than the institutions responsible for the release.

CIMMYT Global Genetic Resources Director and Deputy Director General, Breeding and Genetics, Kevin Pixley also underscored the need to generate more impact through adoption of improved varieties in Africa. Pixley noted that on average, fewer than 30 percent of farmers are using improved varieties of sorghum, millet, and groundnut across the countries with ongoing work.

The meeting heard One CGIAR’s commitment to deliver resilient, nutritious and market preferred varieties as part of its Genetic Innovation Action Area, alongside improving systems and processes for sustainability from CGIAR Senior Director Plant Breeding and Pre-Breeding, John Derera. Speaking in the capacity of IITA’s Breeding Lead, Derera noted the progress made in IITA cowpea breeding program, including its modernization, owing to strong partnerships, cross learning and germplasm exchange between institutions.

PABRA Director & Leader of the Bean Programme at the Alliance of Bioversity International and CIAT, Jean-Claude Rubyogo, pointed out that despite remarkable achievements, such as those witnessed in the bean research, more effort is needed to tackle the challenges of climate change and also increase understanding of consumers traits.

Commenting on innovative pathways to improve adoption of improved varieties, the Director General of the Institute of Agricultural Research (IAR) in Zaria, Nigeria, Mohammad Ishiyaku observed the tendency for some seed companies to continue selling specific seed varieties for years, even when the productivity of the variety is low. He noted the seed companies always claimed consumer preferences concluding then that amidst investor demands, breeders ought to keenly investigate the expectations of consumers and famers to arrive at the best parameters for breeding choices.

International Year of Millets, 2023

The gathering commemorated the International Year of Millets by listening to a keynote address on “Millets for food and nutritional security and mitigating climate change – #IYM2023” by Lake Chad Research Institute, Nigeria, Research Director, Zakari Turaki. The keynote was followed by statements on the importance of millets for various countries and wider Africa from: Sanogo Moussa Daouda, representing Director General of Mali’s Institut d’Économie Rurale (IER); Ibrahima Sarr, Director of Senegal’s Institut Sénégalais de Recherches Agricoles’s Centre National de Recherches Agronomiques; Hamidou Traore, Director of Burkina Faso’s Institut de L’Environnement et de Recherches Agricoles; and Ambrose Agona, Director General of NARO, Uganda.

High-level statements on approaches to gender integration in agricultural research and development were delivered by Scovia Adikini, NARO millet breeder, Geoffrey Mkamillo, Director General of Tanzania’s Agricultural Research Institute (TARI), Francis Kusi of Ghana’s Savanna Agricultural Research Institute (SARI), and Aliou Faye, Director of Senegal’s Regional Center of Excellence on Dry Cereals and Associated Crops (CERAAS).

AVISA Achievements

Finally, this meeting marked the transition from the recently ended Accelerated Varietal Improvement and Seed Systems in Africa (AVISA) project to align with One CGIAR initiatives under the Genetic Innovation Action Area, with specific focus on dryland crops.

Solomon Gyan Ansah, the Director of Crop Services at the Ministry of Food and Agriculture, Ghana, acknowledged the success of AVISA Project and commended the forum’s efforts to build on the gains made by the project in developing the new approach.

“By the end of 2022, AVISA project partners had reached 4.8 million farmers with 30,600 metric tons of seed of improved legume and cereal varieties, covering almost one million hectares of land”, revealed Chris Ojiewo, Strategic Partnerships and Seeds Systems Lead. Other achievements supported by the AVISA Project include upgrading of NARES facilities and building capacities of researchers through short- and long-term trainings.

The meeting was hosted by Ghana Council for Scientific and Industrial Research (CSIR) and Ghana’s Savannah Agricultural Research Institute (SARI), and was organized by CIMMYT, in partnership with IITA and the Alliance of Bioversity and CIAT (ABC).

Kenya Agricultural and Livestock Research Organization (KALRO)’s research station at Kiboko, Kenya, where several partner institutions including the International Maize and Wheat Improvement Center (CIMMYT), conduct significant research activities on crop breeding and seed systems, is now equipped with five new seed drying machines along with a dedicated shed to house these units, a cold room for storing breeding materials, and an additional irrigation dam/reservoir. These infrastructural upgrades are worth approximately US $0.5 million.

During the commissioning of the new facilities on February 7, 2023, CIMMYT Global Maize Program Director, BM Prasanna thanked the donors, Crops to End Hunger (CtEH) Initiative and Accelerated Genetic Gains (AGG) project, that supported the upgrade of the research station, and recognized the strong partnership with KALRO.

“Today is a major milestone for CIMMYT, together with KALRO, hosting this center of excellence for crop breeding. This facility is one of the largest public sector crop breeding facilities in the world, with hundreds of hectares dedicated to crop breeding. These new facilities will enable CIMMYT and KALRO crop breeders to optimize their breeding and seed systems’ work and provide better varieties to the farming communities,” said Prasanna.

Kenya suffered one of its worst droughts ever in 2022, and the newly commissioned facilities will support expedited development of climate-resilient and nutritious crop varieties, including resistance to major diseases and pests.

Improvements and enhancements

The efficiency of the seed driers capabilities to quickly reduce moisture content in seed from above 30% to 12% in two to three days, reducing the time taken for seed drying and allowing for more than two crop seasons per year in a crop like maize.

The additional water reservoir with a capacity of 16,500 cubic meters will eliminate irrigation emergencies and will also enhance the field research capacity at Kiboko. Reliable irrigation is essential for accelerating breeding cycles.

At the same time, the new cold room can preserve the seeds up to two years, preventing the loss of valuable genetic materials and saving costs associated with frequent regeneration of seeds.

World-class research center

“The Kiboko Research Center is indeed growing into an elite research facility that can serve communities in entire sub-Saharan Africa through a pipeline of improved varieties, not only for maize but in other important crops. This will not only improve climate resilience and nutrition, but will contribute to enhanced food and income security for several million smallholder farmers,” said Prasanna.

KALRO Director General Eliud Kireger appreciated the establishment of the new facilities and thanked CIMMYT and its partners for their support.

“Today is a very important day for us because we are launching new and improved facilities for research to support breeding work and quality seed production. This research station is in Makueni County, a very dry area yet important place for research because there is adequate space, especially for breeding,” said Kireger. “We are significantly improving the infrastructure at Kiboko to produce and deliver better seed to our farmers.”

For more than three decades, CIMMYT has conducted research trials at the Kiboko Research Station, focusing on drought tolerance, nitrogen use efficiency, and resistance to pests and diseases, such as fall armyworm and stem borer. The maize Double Haploid (DH) facility established in 2013 at Kiboko, with the support of the Bill & Melinda Gates Foundation, offers DH line production service for organizations throughout Africa, and is key to increasing genetic gains in maize breeding.
