Working with smallholders to understand their needs and build on their knowledge, CIMMYT brings the right seeds and inputs to local markets, raises awareness of more productive cropping practices, and works to bring local mechanization and irrigation services based on conservation agriculture practices. CIMMYT helps scale up farmersâ own innovations, and embraces remote sensing, mobile phones and other information technology. These interventions are gender-inclusive, to ensure equitable impacts for all.
In Nepal, the International Water Management Institute and CIMMYT conducted research on Sustainable Intensification of Mixed Farming System (SI-MFS) in collaboration with local governments in Gurbakot Municipality of Surkhet and Haleshi Tuwachung Municipality of Khotang.
The research found a noticeable shift in farmers’ interest in farming practices, where successful implementation of innovation and scaling, it’s crucial to have farmers’ interest and ownership in interventions.

CIMMYT’s germplasm bank is available worldwide and relies heavily on collaborations with public and private entities, where breeding is a critical part of partnerships to further foster thriving markets.
CIMMYT participated in the inaugural Global Conference on Sustainable Agricultural Mechanization, organized by the Food and Agriculture Organization of the United Nations (FAO) from September 27-29, 2023. The gathering provided space for focused dialogues to prioritize actions and strengthen technical networks for sustainable development of agricultural mechanization.
Bram Govaerts, CIMMYT director general, presented a keynote address on September 27 regarding climate change and mechanization. As a global thought leader and change agent for climate resilient, sustainable and inclusive agricultural development, CIMMYT has many specific initiatives centered on mechanization for facilitating machine innovations and scaling-up improved farming practices for sustainability and farmer competitiveness.

Collaboration is a hallmark of CIMMYTâs endeavors in mechanization, including a strong partnership with local governments across Latin America, Africa and Asia, and international cooperation agencies, supporting the Green Innovations Centers installed by GIZ-BMZ and working on accelerated delivery models together with USAID, in Malawi, Zimbabwe and Bangladesh, to name only a few. Further, local value chain actor engagement is crucial and necessary in this work to connect farmers with viable solutions.
CIMMYT has a long history of leading projects aimed at mechanizing the agricultural efforts of smallholder farmers, including the successful MasAgro Productor in Mexico and FACASI (farm mechanization and conservation agriculture for sustainable intensification) in East and South Africa. At present, the Harnessing Appropriate-Scale Farm Mechanization in Zimbabwe (HAFIZ) project is working towards to improve access to mechanization and reduce labor drudgery while stimulating the adoption of climate-smart/sustainable intensification technologies. The project engages deeply with the private sector in Zimbabwe and South Africa to ensure long-term efficacy.
The Scaling Out Small Mechanization in the Ethiopian Highlands project was active from 2017 to 2022 and increased access for smallholder farmers to planting and harvesting machines. Farmers using two-wheel tractors furnished by the project reduced the time needed to establish a wheat crop from 100 hours per hectare to fewer than 10 hours. CIMMYTâs work was in partnership with the Africa-RISING program led by the International Livestock Research Institute (ILRI) in Ethiopia.
âAt CIMMYT, we work knowing that mechanization is a system, not only a technology,â said Govaerts. âSustainable mechanization efforts require infrastructure like delivery networks, spare parts and capacity development. Working with local partners is the best way to ensure that any mechanization effort reaches the right people with the right support.â

Mechanization is a process of introducing technology or farm equipment to increase field efficiency. CIMMYTâs mechanization work is context specific, to help farmers have access to the appropriate tools that are new, smart and ideal for their unique farming conditions.
Working with the Cereal Systems Initiative for South Asia (CSISA), CIMMYT is leading mechanization efforts in Northern India. Combined with sustainable agriculture, the next generation of farmers now have access to tractors, seeders and other tools that are increasing yield and reducing back-breaking labor.

The delivery of row seeders from India to Benin demonstrates a new path to sustainable South-South business relationships. Developed in India in an iterative design process with farmers, portable row seeders have been a great success. Working with GIC, CIMMYT facilitated a technology and materiel transfer of the portable row seeders to Benin.

Peanuts thrive as a crop in Togo and other West Africa countries, but post-harvest is threatened by aflatoxins, so the entire crop needs to dry. Traditionally, farmers, often women, have dried the peanuts in the open air, subject to weather and other pests. However, CIMMYT, working with GIC, has introduced solar-powered dryers, which speeds up the drying process by a factor of four.
Working with partners in Burkina Faso, CIMMYT is facilitating smallholder mechanization with a model of cascading effects: one farmer mechanizing can then use their skills and eqBMZuipment to help their neighbors, leading to community-wide benefits.

In a September 12 visit to CIMMYT facilities on the agricultural research station of the Kenya Agricultural and Livestock Research Organization (KALRO) at Kiboko, Bram Govaerts, CIMMYT director general, extolled the longstanding partnership with KALRO and suggested creating a platform to speed access of national researchers to improved breeding lines and populations.
Located 155 kilometers southeast of Nairobi in a dryland area better suited to raising cattle, goats, sheep, and camels than row crops, the Kiboko station comprises more than 15,000 hectares, with controlled irrigation systems, and has allowed efficient selection for tolerance to drought and insect pests in Africa-adapted maize, as well as the development of dryland crops such as pigeon pea, sorghum and groundnuts.
“Our recent work where we open up our maize and wheat research platform for dryland crops highlights CIMMYT efforts to diversify cropping options for farmers in challenging settings, enhancing their livelihoods and farming system resilience,â Govaerts said.

Yoseph Beyene, CIMMYT maize breeding coordinator for Africa, described collaborative efforts to speed the breeding and deployment of climate-resilient varieties. âThis work covers maize breeding and seed system networks, participatory engagement with farming communities through on-farm trials, interactions and sharing with global partners, and documenting the adoption of stress tolerant maize in sub-Saharan Africa,â Beyene explained.
CIMMYT data show that drought-tolerant maize varieties derived from shared research of the Center, CGIAR and partners are being sown on more than 6 million hectares in 9 countries of eastern and southern Africa, benefitting an estimated 38 million people and producing additional grain worth as much as US$1.5 billion each year.
Beyene added that the expansion of on-farm testing to over 1,000 locations in eastern and southern Africa has enabled CIMMYT to assess preferences and genotype-by-environment interactions which, along with support from the seed systems team regarding small-scale farmersâ acceptance of drought-tolerant maize hybrids, have underpinned the development of successful hybrids.
A prominent stop on Govaertsâs tour was the maize double haploid (DH) facility established in Kiboko in 2013, with funding from the Bill & Melinda Gates Foundation.

Long used by private seed companies, the double haploid approach generates inbred lines that are completely âhomozygous,â wherein genes on each pair of chromosomes are identical. It achieves this in a single year, compared to three to four years for conventional inbreeding, which can produce lines that may not be purely homozygous and are thus less useful for breeders.
âThe facility offers double haploid line production services for organizations throughout Africa and is key to increasing genetic gains in maize breeding,â said Aparna Das, technical program manager for CIMMYTâs Global Maize Program.
Govaerts also visited the fall armyworm (FAW) artificial screening site and experiments in which CIMMYT scientists are evaluating five new FAW-tolerant experimental varieties for possible sharing with partners. In the fall armyworm screening facility, a team works to integrate and test ecofriendly crop management solutions against fall armyworm, critical research to safeguard agricultural production against this highly destructive insect pest.
âThe excellent teamwork and facilities at Kiboko point up multiple opportunities for KALRO and CIMMYT to continue joint work that advances agricultural science to benefit farmers and consumers,â Govaerts concluded.
CIMMYT scientists, researchers and subject experts participated in the Zimbabwe Agricultural Show (ZAS) from August 28âSeptember 2 in Harare, Zimbabwe. The 113th edition ran under the theme âSustained Growth. Adaptation. Productivity. Linkages.â
âCIMMYT has a long history of working with local partners in Zimbabwe. Together with these partners, we work to improve the livelihoods and resilience of smallholder farmers, through innovations we develop like stress resilient maize or wheat varieties, together with conservation agriculture technologies,â said Mainassara Zaman-Allah, CIMMYT Zimbabwe country representative.

With an average of 200 visitors per day at CIMMYTâs stand, stemming from small-scale farmers, government representatives, seed companies, university personnel, NGOs and media among others, this platform continues to pave the way for synergies, learning and networking. Beyond raising awareness on the progressive work being done, CIMMYT used this opportunity to interact with local seed companies (SEEDCo, Agriseeds, K2, among others) and get valuable feedback from farmers, including those involved in the maize regional on-farm variety evaluation.
The place to be for agricultural development in Zimbabwe
The Zimbabwe Agricultural Show, organized by the Zimbabwe Agricultural Society, is a dynamic event that serves as the premier platform for the facilitation and promotion of agricultural development in Zimbabwe. With over 550 commercial exhibitors, 700 farmers, 200 micro enterprises, the show presents a unique business opportunity for national and regional organizations.
The event provides a platform to showcase brands, market services, and engage in various business discussions targeting important sectors. The show is capped by the Annual National Agribusiness Conference.
Advancing innovation in Zimbabwe
The Zimbabwe Agricultural Show served as an ideal platform for CIMMYT to share its research findings, exchange knowledge and foster collaborations with farmers, policymakers and other stakeholders in the agriculture sector.
CIMMYT staff provided information regarding its ongoing initiatives and the transformative potential of innovations. We encouraged participants, partners and value chain players to visit the CIMMYT booth to engage with researchers, explore our latest research and discuss innovative agricultural practices.

“Our work in Zimbabwe, like promoting the increased adoption of climate-resilient innovations in mixed crop-livestock production systems and strengthening local food systems through agroecological advances, would not be possible without the strong collaborations with local partners,â said Isaiah Nyagumbo, regional cropping systems agronomist. âAnd the Zimbabwe Agricultural Show is the best place to continue those partnerships and start new linkages.â
ZAS and CIMMYT
Established in 1895 and operating from The Business Hub (Formerly Exhibition Park), the ZAS is the epicenter for the promotion and facilitation of national agricultural development. It is the oldest convenor and host of agricultural, commercial, and industrial shows in Zimbabwe.
CIMMYT is a core CGIAR Research Center dedicated to reducing poverty, enhancing food and nutrition security, and preserving natural resources in the Global South.
Seed the World Group hosted a webinar to find a common ground between public and private breeding programs in North America and some possible paths forward. Fernando Gonzalez, a retired plant breeder from CIMMYT mentioned a noticeable uptick in the involvement of the private sector in breeding programs in Mexico.

Erratic climate patterns, global and regional conflicts, biodiversity degradation, and insufficient funding for agricultural research pose a serious risk to meeting global food production goals by mid-century, according to Cary Fowler, the U.S. special envoy for food security.âŻÂ
The world must produce 50-60% more food by 2050 to nourish a growing population. Yet global crop yields are projected to drop between 3-12% over the same period. Wheat yields in Africa and South Asia, two regions with the fastest growing and youngest populations, are expected to decline by 15% due to global warming. Food systems have also been disrupted by the Russia-Ukraine conflict and the COVID-19 pandemic, raisingfood and fertilizer prices, and exacerbating regional instability. âŻÂ

Fowler cites inadequate government funding for plant breeding programs as a contributor to an ineffective response to introducing improved climate-adaptable staple crops. âWith the state of current affairs, we are on our way to failing to feed the world by centuryâs end,â said Fowler.âŻÂ
Global peace and development efforts will demand a cross-sector and coordinated response. Through its 2030 Strategy, CIMMYT has laid out a robust series of investments in crop systems innovation, partnership, and sustainable development, to advance more resilient food systems. The 2030 Strategy consolidates CIMMYTâs target areas through three pillars: Discovery, SystemDev, and Inc. These pillars focus on research and innovation, systems approach, and strong partnerships and advocacy efforts with the private and government sectors to address an emerging food crisis.Â
âOur 2030 Strategy places research, innovation and partnership at the center of facing the challenges of the 21st century to solve tomorrowâs problems todayâfor greater food security and the prosperity of smallholder farmers. As we implement work plans, CIMMYT is proud of the achievements it has seen through projects in sub-Saharan Africa, our contribution to influential policy reports, and continued praise for our agri-development initiatives in Latin America. All these feats will help us deliver on and expand our efforts to reach our 2030 vision,â said Bram Govaerts, CIMMYT director general. Â
CIMMYT remains prominent in developing sustainable solutions for farmers and policy actors Â
CIMMYT has achieved important progress in Eastern and Southern Africa. Projects such as the Southern Africa Accelerated Innovation Delivery Initiative (AID-I) Rapid Delivery Hub have brought together regional seed partners, government agencies, and CGIAR Research Centers, to reduce fertilizer prices, boost resilience to drought and pests, and facilitate market access for smallholders. Â
In the recent SPG Coalition report, CIMMYT featured prominently as a leading organization in climate-smart agriculture, nutrient-use efficiency, and pest and fertilizer management. This report informs researchers, non-governmental organizations and private sector partners in agrifood and climate policy development. Â

MasAgro, a research-for-development initiative, has received praise by international organizations and governments as an exemplary program for sustainable development in Latin America. Over 500,000 farmers in Mexico have adopted hardy maize or wheat varieties and resource-conserving agricultural practices. To maximize on the experience of MasAgro, CIMMYT has partnered with a CGIAR initiative: AgriLAC Resiliente. This initiative aims to bolster the competitiveness and sustainability of agrifood systems to respond to forced migrations in Central and South America which are worsened by regional food insecurity and conflict. Â
Science and innovation powered by partnership can deliver a food secure world Â
Climate change undoubtedly threatens global peace and agrifood systems. With over 130 countries depending on food imports, todayâs hyper-connected world demands collaborative partnership across all sectors to build up shockproof food systems. Through a grassroots approach to research and innovation, the CIMMYT 2030 Strategy is built upon decades of applied science which has impacted communities around the world, to continue influencing policy, pioneering innovations, and advocating for the development of a food secure future. Â
Women play a critical role in the future of food security. Female farmers face a significant disadvantage before they ever plow a field or sow a seed. Farming is a challenging profession, and it is even more challenging for women when they perform these functions whilst facing numerous constraints.

Millions of rural Indians, mostly farmers, are at the mercy of changing weather and climate change. Rising temperature and heat stress, unpredictable rainfall patterns, increasing drought-like situations, soil erosion and depleting water tables are leading to poorer yields and reduced income for farmers. While the agricultural sector and farmers are most affected by the adverse impacts of climate change, it is also one of the sectors significantly responsible for greenhouse gas emissions, contributing about 14% of the total greenhouse gas emissions in the country.

Good agronomy and soil management through conservation agriculture practices such as no-till farming, crop rotation, and in-situ crop harvest residue management are resource efficient and help reduce greenhouse gas emissions significantly. The intensification of these conservation agriculture practices by the Cereal Systems Initiative for South Asia (CSISA)âa regional project led by CIMMYT to sustainably enhance cereal crop productivity and improve smallholder farmersâ livelihoods in Bangladesh, India, and Nepalâand partners is helping smallholder farmers to improve their yield and income with less input costs.
Climate smart agriculture
Over 70% of Bihar’s population is engaged in agriculture production, with wheat and rice as the two major crops grown in the state. Bordering Uttar Pradesh, Buxar, is one of the many rural districts in Bihar, with over 108,000 hectares of land used for agriculture. The area is plain, fertile and has good irrigation facilities. The rice-wheat cropping system forms the dominant practice here, and pulses and other non-cereal crops are grown additionally during winters.
CSISA began promoting zero tillage in wheat cultivation in the area in 2010. Along with Krishi Vigyan Kendras (KVKs), and local agriculture departments, awareness and frontline demonstrations on different best management practices were conducted to inform farmers of alternative approaches to cultivating wheat and rice sustainably. Farmers were used to conventional farming methods, with more input costs and labor-intensive practices. In addition, as farmers were growing long-duration rice varieties, they typically sowed wheat in late November to early December, which meant harvesting in late April/May. Harvesting wheat this late caused yield losses due to terminal heat stress at the grain filling stage. With increasingly hot temperatures in recent years due to climate change, yield loss in wheat is imminent.
To help curb these yield losses, researchers and officials began promoting early sowing of wheat through a technology called zero tillage in the region, with sowing recommended before mid-November. As expected, this helped farmers to escape high temperature stress at the time of the dough stage, thus, saving grain shrinkage and yield loss at harvest. Zero tillage technology is a tested method with the potential to increase crop productivity through better time management and reduced input cost.
Deepak Kumar Singh, scientist at CSISA who has been supporting agri-extension efforts in the region for nearly a decade recalled how CSISA and partners were able to get more farmers on board with zero tillage and early wheat sowing:
“The best practices of zero till technology and early wheat sowing were encouraged widely through exposure visits, demonstration trials on progressive farmers’ fields, and providing support from local KVKs for machines and quality seeds, including the promotion of private service providers,” he said.
As more farmers were reached through field events, with visible on-field results during public harvest activities held at demonstration fields by CSISA and KVKs, the region gradually adopted early wheat sowing, zero tillage and direct seeded rice technologies. Currently, in the district, it is estimated that over 40% of wheat cultivation under the rice-wheat system is through zero till, helping farmers obtain better yield and profits.
Rice-wheat cropping systems, resilient and sustainable in increasingly changing climate
Rajapur, a small village in Buxar district, boasts 100% adoption of zero tillage in wheat cropping. We met farmer Rahul Rai whose family has been involved in farming for generations. The family owns over thirty acres of land with agriculture as the primary source of income. His father and his siblings were used to conventional farming methods. The produce from their farm was sufficient for household consumption and with the little extra left, they sold and made some income. On the significance of agriculture and farming for his family, Rahul Rai says, “this farmland has been feeding and supporting 17 members in our joint household.”
When young Rahul Rai got down to work in the family fields in the early 2000s, he was keen to explore possibilities to improve the income generated from the farm. Initially, like many others, he was engaged in intensive farming. According to Rai, “with the input costs rising daily, including scarce labor and soil health deterioration, bringing in some extra income seemed unsustainable”.
He first met researchers from the CSISA project and local KVK scientists in early 2011 in the neighboring village. The team was there to inform farmers about conservation agriculture practices and how to better manage yield and maintain soil health. Rai soon became more curious about the benefits of adopting these new methods over conventional practices. He started with a few acres with zero tillage and began sowing wheat by early November, as recommended by the scientists. In Rabi 2022-23, his wheat fields were sown by November 11, compared to the early years when the sowing date was around December.
Wheat yield data gathered meticulously over a decade from Rahul Rai’s fields (Data: CSISA MEL team)
With more participation and engagement with CSISA, in 2017, he joined other farmers from the region on an exposure visit to Patna organized by the CSISA-KVK network. In Patna, at the Indian Council of Agri Research – Research Complex for Eastern Region (ICAR-RCER), Rai and the visiting farmers were introduced to conservation agri-technologies for rice-wheat and other cropping systems. During the visit, they were informed about crop rotation and diversification, new seed varieties that are resilient and adaptable to changing climates, efficient use of plant protection chemicals and fertilizer and various subsidies from the center/state government to farmers. He later accompanied other progressive farmers on a CSISA-led travel seminar to Gorakhpur in 2017, where he observed acres and acres of wheat fields cultivated through zero tillage and early sowing that had yielded 6-7 tons per hectare (t/ha) on average.
At present, Rai’s family cultivates only zero till wheat in their fields and direct seeded rice on a few acres where irrigation facilities are well established. Rai asserts that until 2014, the wheat yield was about 10-15 quintals per acre (3.5-4 t/ha), rising to around 20-25 quintals per acre on average (5.5 t/ha in 2023) in recent years, thanks to conservation agriculture practices.
Today, the CSISA team has system optimization and demonstration trials on fields owned by Rai’s family where they conduct trials to demonstrate the importance and feasibility of different agri-practices and compare yields at harvest. Rai, a champion farmer who has been involved with CSISA for nearly a decade, said, “I am a collaborator with CSISA now. The data gathered from my fields on the compounding benefits of conservation agriculture technologies is used to promote the best practices and technology adoption across our district and state.”
One village at a time
Presently, Rajapur village has 100% zero tillage adoption. Despite most farmers being smallholders, this level of zero tillage adoption in wheat is impressive. Zero-till-based crop establishment, with appropriate diversification in crops grown, is economically beneficial and improves soil health. All these practices and technologies ensure lower greenhouse emissions and support climate change mitigation efforts. Above all, smallholder farmers are food secure and contributing in their small way to national and global food security.
To scale the adoption of conservation agriculture practices, CSISA and partners are collaborating with farmers in the district/state â many of whom are already 50-80% in zero tillage adoption. The team on the ground are conducting system optimization trials on farmers’ fields to generate data and evidence to support and strengthen policies and assist in integrating market intelligence to support access and availability of technology to all smallholders. Every year steadily, through a smallholder farmer, a village, a district, the effort is to slowly expand the area under conservation agriculture across the state and region and ensure increased system productivity and sustainability of agriculture.

In 2015, the General Assembly of the African Union committed to retiring the hand hoe to museums and pushing for sustainable agricultural mechanization on the African continent.
Today, approximately 75-82% of smallholder farmers in eastern and southern Africa rely on human or animal draft power for primary tillage operations. Mechanization helps to reduce drudgery, increases productivity, and contributes to food security and increased livelihoods.
What is Feed the Future Mechanization and Extension Activity?
The Feed the Future Mechanization and Extension Activity, funded by the United States Agency for International Development (USAID), aims to improve smallholder farmersâ access to farm power and machinery to enhance their land and labor productivity.
This is achieved through three integrated components that stimulate demand for scale-appropriate machinery.
Components:
 Identification of demand-driven smallholder farm machinery and building capacity of manufacturing companies to produce, repair, and import machinery for smallholder agricultural production systems.
Building the capacity of local service providers to purchase, operate, and maintain farm machinery to provide mechanized services to small-scale agricultural value chain actors.
Coordinate and collaborate with other FTF activities to build the capacity of interested local service providers.
What are the objectives?
Assess and build the capacity of smallholder machinery manufacturers and suppliers to manufacture demand-driven farm machinery.
Enhance land and labor productivity and income through the establishment of mechanization service provision to small scale agricultural value chain actors.
Promote the use of the machinery through demonstrations and other demand creation activities, and inclusive training of rural women and youth in post-harvest processing of agricultural produce to generate increased income.
Coordinate and collaborate with other mechanization and Feed the Future activities to build capacity of the interested service providers to be agricultural extension agents to their customers during the cropping season.
Support service providers, manufacturers, and distributors to access credit to acquire machinery or mechanized services.
The project sites are located in Zimbabwe’s Manicaland and Masvingo provinces with project presence implemented across 10 districts.
The Mechanization and Extension Activity will directly benefit 150 service providers who in turn will reach up to 22,500 women and men smallholder farmers through provision of mechanized services. In addition, the mechanization activity will identify and build the capacity of 30 rural mechanics and 30 technicians drawn from local farm machinery manufacturing companies and/or small and medium enterprises.
The introduction of mechanisation in agricultural practices has ensured the promotion of technology and conservation of agriculture to stimulate smallholder production and the preservation of climate-proofing farming practices in Zimbabwe.
CIMMYT hosted a meeting, to discuss how the HAFIZ project has set the foundation for harnessing farm mechanization in Zimbabwe, shaping the future of mechanisation policies and interventions in Zimbabwe. As well as future initiatives to improve technology to sustain growth and master the impact of climate change.
The Livestock Production Systems in Zimbabwe (LIPS-Zim) project implemented by CIMMYT and various research institutions in partnership with the government expects to increase incomes and ensure food security for more than 50,000 rural Zimbabweans.
In plant breeding, efforts to increase the rate of genetic gains and enhance crop resilience to the effects of climate change are often limited by the inaccessibility and costs of phenotyping methods. The recent rapid development of sensors, image-processing technology and data analysis has provided new opportunities for multiple scales phenotyping methods and systems. Among these, satellite imagery may represent one of the best ways to remotely monitor trials and nurseries planted in multiple locations, while standardizing protocols and reducing costs.
This is because relevant data collected as part of crop phenotyping can be generated from satellite images. For instance, the sensors onboard the SkySat satellite constellation of Planet Labs have four spectral bandsâblue, green, red, and infraredâwhich can be used to calculate the normalized difference vegetation index (NDVI), which is a measure of vegetation and its greenness, and various canopy traits like ground cover, leaf area index and chlorosis. It can also be used to monitor plot establishment and phenological parameters.

The use of satellite-based phenotyping in breeding trials has typically been restricted by low resolution, high cost and long intervals between fly-overs. However, the advent of a new generation of high-resolution satellitesâsuch as the SkySat constellationânow offers multispectral images at a 0.5m resolution with close to daily acquisition attempts on any place on Earth. This could be a game changer in terms of the scale at which yield trials can be conducted, enabling more precise variety placement and thereby increasing genetic diversity across farmerâs fields and reducing the probability of disease epidemics. It could also revolutionize the capacity for research in realistic field conditions, since traits can be measured throughout the cycle in a highly standardized way, over multiple sites at low cost. For example, an image which covers 25 km2 can monitor an entire research station at a cost of about US$300.
To test the suitability of this technology, a team of researchers from CIMMYT set out to evaluate the reliability of SkySat NDVI estimates for maize and wheat breeding plots of different sizes and spacing, as well as testing its capacity for detecting seasonal changes and genotypic differences.
Both their initial findings, recently published in Frontiers in Plant Science, and more recently acquired data, show that the SkySat satellites can be used to monitor plots commonly used in wheat and maize nurseries. While wheat yield plots usually are 1.2m wide, maize plots tend to consist of at least two rows, resulting in a width of 1.5m. Plot length ranges from 2-4m. The authors also discuss on other factors to be considered when extracting and interpreting satellite data from yield trials, such as plot spacing.
Through the successful collection of six satellite images in Central Mexico during the rainy season and parallel monitoring of a maize trial in Zimbabwe, the researchers demonstrate the flexibility of this tool. Beyond the improvement of spatial resolution, the researchers suggest that the next challenge will be the development and fine-tuning of operational procedures that ensure high quality, standardized data, allowing them to harness the benefits of the modern breeding triangle, which calls for the integration of phenomics, enviromics and genomics, to accelerate breeding gains.
This research was supported by the Foundation for Food and Agriculture Research, the CGIAR Research Program on Maize, the CGIAR Research Program on Wheat, and the One CGIAR Initiatives on Digital Innovation, F2R-CWANA, and Accelerated Breeding.
The inaugural Rwanda National Seed Congress, which took place in Kigali on July 31 and August 1, 2023, marked a significant milestone for the country’s seed industry. Themed âPrivate Sector Strategic Roadmap for the Seed Industry 2030â, the event brought together key stakeholders from the government, public, and private sectors to address challenges and opportunities in the national seed value chain.
Discussions centered around pertinent issues concerning the seed sector in general, with a particular focus on the Rwandan National Seed Strategic Roadmap. This document, which was developed through consultations with various stakeholders, provides a comprehensive plan to steer the industry towards success and sustainable growth.
âEnhancing and managing the seed system is a complex endeavor that requires the collaboration of various stakeholders,â said Chris Ojiewo, CGIAR Seed Equal Initiative lead. âThis is where public-private partnerships come in as a valuable tool for nurturing the growth and expansion of the seed industry.â

During a presentation entitled Public-private Partnership: A Tool for Development and Strengthening of the Seed Sector, Ojiewo highlighted the growing importance of collaboration and partnerships in the current seed system. He emphasized that the processes and elements that shape the seed sector are complex and extensive, making it too much for any one organizationâwhether public or privateâto handle alone.
The way forward
During the congress, several key recommendations were proposed  to increase the potential of the seed industry. The government was encouraged to seek accreditation with major seed industry quality organizations, such as the International Seed Testing Association (ISTA) and Organization for Economic Co-operation and Development (OECD) certification schemes, while adopting International Union for the Protection of New Varieties of Plants (UPOV) to establish an improved regulatory environment conducive to industry growth.
The empowerment of the National Seed Association of Rwanda (NSAR) as an advocate and facilitator for the seed industry was also highlighted as an essential measure. The government’s support in enabling the seed association to become increasingly self-regulatory is seen as crucial to the industry’s growth over the next seven years, with private seed industry players developing internal systems to ensure compliance with rules and regulations.
Another key recommendation for increasing sustainable improved seed use in Rwanda was the use of Public-Private Partnerships (PPPs), which will play a critical role in promoting the country as a seed production and trade investment destination.
Ojiewo emphasized the importance of such partnerships, noting that âPPPs have the potential to transform the seed industry by leveraging the strengths of different organizations.â He further highlighted that in addressing the challenges of global food security and sustainable development, the way forward becomes clear through collaboration, innovation, and a shared commitment to advancing agricultural progress through collaborative efforts.
The congress also focused on attracting affordable financing to scale up investments throughout the seed value chain. It was considered essential to involve industry financial players in the development of optimal financing structures to support the expansion of the industry.
As a result of the successful event, plans have already been made for the second National Seed Congress in 2024. Scheduled to take place in Kigali on July 29 and 30, 2024, the next event aims to build on the achievements of the first congress and further drive the growth of Rwanda’s seed industry.
CGIARâs Seed Equal Initiative helps farmers by providing them with better seeds that are nutritious, preferred in the market, and that can withstand climate change. These varieties have been carefully developed to exhibit significant genetic advancements, ultimately benefiting farmers. It also makes sure that women and other marginalized groups have fair access to these seeds.
