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 farmers’ own innovations, and embraces remote sensing, mobile phones and other information technology. These interventions are gender-inclusive, to ensure equitable impacts for all.
Society faces enormous challenges in the transition to sustainable rural development. We are unlikely to make this transition unless we move away from the 20th-century paradigm that sees the world as a logical, linear system focused on “scaling up” the use of technologies to reach hundreds of millions of smallholders.
In a new article published this week on NextBillion, Lennart Woltering of CIMMYT contends that “farming communities are unlikely to continue using a new practice or technology if the surrounding system remains unchanged, since it is this very system that shaped their conventional way of farming.”
Woltering calls on the research for development community to work towards producing deeper system change and offers some key considerations for moving in the right direction.
A study by the International Maize and Wheat Improvement Center (CIMMYT), carried out in collaboration with Stanford and Cornell Universities, has shown that there is a sustainable way to increase food production already in the fields: microsatellites. Read more here (in Italian).
Simon N. Groot is the winner of the 2019 World Food Prize. With this award, food and agriculture leaders recognize his work to increase vegetable production in more than 60 countries, through the development of high-quality seeds and training programs for farmers.
Groot’s efforts were crucial in leading millions of farmers to become horticulture entrepreneurs, resulting in improved incomes and livelihoods for them, and greater availability of nutritious vegetables for hundreds of millions of consumers.
Like small-town Iowa farm boy Norman Borlaug, Groot comes from a small town in the Netherlands, where he learned the value of seeds at a young age. Both shared the same vision to feed the world and succeeded.
“I think I was born to be a vegetable seedsman.”
– Simon N. Groot
Groot devoted his whole life to the seed and plant breeding industry. After 20 years in the industry in Europe and North America, Groot travelled to southeast Asia at the age of 47 with a vision to set up the region’s first vegetable seed breeding company. Frustrated by the poor quality seeds he found and noticing a total lack of commercial breeding activities in the region, Groot decided to set up his own company, using his own capital, partnering with Benito Domingo, a Philippines local with a passion for seeds and local connections to the traditional seed trade, agriculture industry and universities.
The company, named East-West Seed Company, started out as a small five-hectare farm outside Lipa City, Philippines. Groot brought over well-trained plant breeders from the Netherlands to begin plant breeding and help train locals as breeders and technicians. Groot was the first to introduce commercial vegetable hybrids in tropical Asia: varieties which were high-yielding, fast-growing and resistant to local diseases and stresses. Today, East-West Seed Company has over 973 improved varieties of 60 vegetable crops which are used by more than 20 million farmers across Asia, Africa and Latin America.
Inspired by Borlaug
Groot described meeting Dr. Borlaug at a conference in Indonesia in the late 1980s as “a pivotal moment” for him, writing that “his legacy has continued to serve as an inspiration for everything I have done at East-West Seed.”
In response to being awarded the 2019 World Food Prize, Groot wrote: “Bringing about the ‘Vegetable Revolution’ will be a fitting tribute to the work of Dr. Borlaug.”
The World Food Prize has been referred to as the “Nobel Prize for food and agriculture.” Awarded by the World Food Prize Foundation, it recognizes individuals who have advanced human development by improving the quality, quantity or availability of food in the world. Winners receive $250,000 in prize money.
The World Food Prize was founded in 1986 by Norman Borlaug, recipient of the 1970 Nobel Peace Prize.
“We are talking about testing whether it is possible to use information available in the genome to predict how productive a variety of wheat will be, if it will be drought- or heat-resistant and what quality its grain will have,” explains Carlos Guzmán from the University of Cordoba who participated in the study via his work as head of the Chemistry and Wheat Quality Laboratory at CIMMYT in Mexico.

To meet the demand for wheat from a rising and quickly urbanizing population, wheat yields in farmers’ fields must increase by an estimated 1.5% each year through 2030.
Of all the factors that influence yield, grain weight is the trait that is most stable and heritable for use in breeding improved wheat varieties. Breeders measure this by thousand grain weight (TGW).
Over the years, molecular scientists have made efforts to identify genes related to increased TGW, in order to speed up breeding through marker-assisted selection (MAS). Using MAS, breeders can select parents that contain genes related to the traits they are looking for, increasing the likelihood they will be passed on and incorporated in a new variety.
There have been some limited successes in these efforts: in the past years, a few genes related to increased TGW have been cloned, and a set of genetic markers have been determined to be used for MAS. However, the effects of most of these candidate genes have not yet been validated in diverse sets of wheat germplasm throughout the world that represent the full range of global wheat growing environments.
A group of wheat geneticists and molecular breeders from the International Maize and Wheat Improvement Center (CIMMYT) has recently conducted a thorough study to confirm the effects of the favorable alleles reported for these genes on TGW in CIMMYT wheat, and to identify new genetic determinants of this desired trait.
They found some good news and some bad news.
First, the good news: focusing on more than 4,000 lines of CIMMYT wheat germplasm they found 15 haplotype blocks significantly associated with TGW. Four haplotype blocks associated with TGW were also associated with grain yield — a grand prize for breeders, because in general the positive association of grain yield with TGW is less profound and sometimes even negative. However, of the 14 genes that had been previously reported to increase TGW, only one in CIMMYT’s 2015-2016 Elite Yield Trial and two in Wheat Associative Mapping Initiative panel were shown to have significant TGW associations.

The scientists also found that the alleles — pairs of genes on a chromosome that determine heredity — that were supposedly favorable to TGW actually decreased it. These candidate genes also appear to vary in their TGW effects with genetic background and/or environment.
Thus, these findings also provide a foundation for more detailed investigations, opening the door for more studies on the genetic background dependence and environment sensitivity of the known candidate genes for TGW.
“Our findings indicate that it will be challenging to use MAS based on these existing markers across individual breeding programs,” said Deepmala Sehgal, CIMMYT wheat geneticist and the primary author of the study.
However, efforts to identify new genetic determinants of TGW were promising. The authors’ study of CIMMYT germplasm found one locus on chromosome 6A that showed increases of up to 2.60 grams in TGW and up to 258 kilograms per hectare in grain yield.

This discovery expands opportunities for developing diagnostic markers to assist in multi-gene pyramiding — a process that can derive new and complementary allele combinations for enhanced wheat TGW and grain yield.
Most of all, the study highlights the strong need for better and more validation of the genes related to this and other traits, so that breeders can be sure they are using material that is confirmed to increase wheat grain weight and genetic yield.
“Our findings are very promising for future efforts to efficiently develop more productive wheat in both grain weight and grain yield,” said Sehgal. “This ultimately means more bread on household tables throughout the world.”
“Validation of Candidate Gene-Based Markers and Identification of Novel Loci for Thousand-Grain Weight in Spring Bread Wheat” in Frontiers in Plant Science by Deepmala Sehgal, Suchismita Mondal, Carlos Guzman, Guillermo Garcia Barrios, Carolina Franco, Ravi Singh and Susanne Dreisigacker was supported by funding from the CGIAR Research Program on Wheat (WHEAT), the Delivering Genetic Gain in Wheat (DGGW) project funded by the Bill & Melinda Gates Foundation and the UK Department for International Development (DFID), and the US Agency for International Development (USAID) Feed the Future Innovation Lab for Applied Wheat Genomics.

These awards recognize the contributions of young women and men under 35 who are implementing innovations in Latin American maize-based agri-food systems, including research for development, seed systems, agribusiness, and sustainable intensification.
The winners will attend the 23rd Latin American Maize Reunion (XXIII Reunión Latinoamericana del Maíz) in Monteria, Colombia, where they will receive their awards and present their work. Award recipients may also get the opportunity to collaborate with MAIZE and its partner scientists in Latin America on implementing or furthering their innovations.
This is the third instalment of the awards, following Asia in October 2018 and Africa in May 2019.
Congratulations to this year’s winners, seven exceptional young people working in Latin American maize-based systems:
Eduardo Cruz Rojo.
Eduardo Cruz Rojo (Mexico) – Farmer category
Eduardo Cruz Rojo is a young agricultural entrepreneur, worried about rural out-migration in his region and about the poor agricultural practices that have led farming to cease to be profitable. He has a degree in logistics, and is originally from Alfajayucan, in Mexico’s state of Hidalgo. For the past four years he has been working on maize research and production, with a focus on improved agronomic practices that help farmers increase their yields. This includes soil improvement, organic fertilizers, earthworm compost and biological pest control. Through research and testing, he has shown smallholder farmers the cost-benefit of improved agricultural practices. This has been reflected in local farmers achieving improved soils and yields in an environmentally friendly manner.
Yésica Chazarreta has a degree in genetics and is currently a doctoral fellow at the Scientific and Technologic Fund, working with the Crop Ecophysiology group at the National Agricultural Technology Institute (INTA) Pergamino in Buenos Aires, Argentina. Her work centers on understanding the genetic and environmental control of the physiological determinants of filling, drying and quality of maize grains in genotypes destined for grain or silage. The objective is to generate knowledge to continue advancing in maize production improvement and to open the possibility of establishing improvement programs differentiated by planting times for her region, as well as to provide valuable information for the creation of mechanistic models to predict the evolution of humidity in maize grains. This information can help farmers make more informed decisions about the best time to harvest. In addition, Chazarreta hopes to deepen understanding of maize biomass quality for animal feed, a practice that has increased in her native country, Argentina, due to changes in crop management practices related to delays in planting dates.
Omar Garcilazo Rahme is a postgraduate student researching sustainable management of agro-ecosystems at the Meritorious Autonomous University of Puebla (BUAP).
A food engineer by training, he has a profound interest in Mexico’s bio-cultural heritage and maize as a staple food in his native country, as well as the various methods to produce and conserve the crop. His research project seeks to improve the economic, nutritious and sociocultural benefits associated with the production of maize.
He is currently collaborating in a technology transfer and innovation agency on the topics of nutritional labeling, big data and applied technology solutions for the agri-food industry.

Data from microsatellites can be used to detect and double the impact of sustainable interventions in agriculture at large scales, according to a new study led by the University of Michigan (U-M).
By being able to detect the impact and target interventions to locations where they will lead to the greatest increase of yield gains, satellite data can help increase food production in a low-cost and sustainable way.
According to the team of researchers from U-M, the International Maize and Wheat Improvement Center (CIMMYT), and Stanford and Cornell universities, finding low-cost ways to increase food production is critical, given that feeding a growing population and increasing the yields of crops in a changing climate are some of the greatest challenges of the coming decades.
“Being able to use microsatellite data, to precisely target an intervention to the fields that would benefit the most at large scales will help us increase the efficacy of agricultural interventions,” said lead author Meha Jain, assistant professor at the U-M School for Environment and Sustainability.
Microsatellites are small, inexpensive, low-orbiting satellites that typically weigh 100 kilograms or less.
“About 60-70% of total world food production comes from smallholders, and they have the largest field-level yield gaps,” said Balwinder Singh, senior researcher at the International Maize and Wheat Improvement Center (CIMMYT).
To show that the low-cost microsatellite imagery can quantify and enhance yield gains, the researchers conducted their study in smallholder wheat fields in the Eastern Indo-Gangetic Plains in India.
They ran an experiment on 127 farms using a split-plot design over multiple years. In one half of the field, the farmers applied nitrogen fertilizer using hand broadcasting, the typical fertilizer spreading method in this region. In the other half of the field, the farmers applied fertilizer using a new and low-cost fertilizer spreader.
To measure the impact of the intervention, the researchers then collected the crop-cut measures of yield, where the crop is harvested and weighed in field, often considered the gold standard for measuring crop yields. They also mapped field and regional yields using microsatellite and Landsat satellite data.
They found that without any increase in input, the spreader resulted in 4.5% yield gain across all fields, sites and years, closing about one-third of the existing yield gap. They also found that if they used microsatellite data to target the lowest yielding fields, they were able to double yield gains for the same intervention cost and effort.
“Being able to bring solutions to the farmers that will benefit most from them can greatly increase uptake and impact,” said David Lobell, professor of earth system science at Stanford University. “Too often, we’ve relied on blanket recommendations that only make sense for a small fraction of farmers. Hopefully, this study will generate more interest and investment in matching farmers to technologies that best suit their needs.”
The study also shows that the average profit from the gains was more than the amount of the spreader and 100% of the farmers were willing to pay for the technology again.
Jain said that many researchers are working on finding ways to close yield gaps and increase the production of low-yielding regions.
“A tool like satellite data that is scalable and low-cost and can be applied across regions to map and increase yields of crops at large scale,” she said.
The study is published in the October issue of Nature Sustainability. Other researchers include Amit Srivastava and Shishpal Poonia of the International Maize and Wheat Improvement Center in New Delhi; Preeti Rao and Jennifer Blesh of the U-M School of Environment and Sustainability; Andrew McDonald of Cornell; and George Azzari and David Lobell of Stanford.
William Penn University’s Health & Life Sciences Division welcomed students, staff, faculty, and community members at the annual World Food Prize lecture on Wednesday, Oct. 16.

New research by an international team of scientists, including International Maize and Wheat Improvement Center (CIMMYT) Director for the Integrated Development Program, Bram Govaerts, outlines a proposed accounting system for organic carbon in soils that could encourage farmers to adopt better land management practices and increase levels of organic carbon in their soil.
Reported this month in the journal Carbon Management, the study highlights how increasing soil organic carbon (SOC) would build agricultural resilience and fertility and reduce greenhouse gas emissions — but we need to be able to measure it.
Soil is a huge carbon reservoir — in fact, soils contain one of the largest organic carbon stocks on the planet. With proper land management, soils have the potential to store even more. Improved SOC levels have also been connected with improved soil quality, reduced susceptibility to erosion and greater agricultural yields and yield stability, particularly under drought. This makes them a crucial player in climate change mitigation and agricultural resilience.
Policy makers and environmental groups are becoming increasingly interested in soil health and its effect on climate change. The 4 per 1000 initiative, launched at the COP 21 climate talks in Paris in 2015, argues that an annual growth rate of 0.4% in soil carbon stocks would significantly reduce human activity-related CO2 concentrations in the atmosphere. The most recent Intergovernmental Panel on Climate Change (IPCC) assessment highlights carbon sequestration as one of the options, alongside massive fossil fuel reduction, to keep warming below 2 degrees Celsius, in accordance with the Paris Climate Agreement.
Increasing organic carbon content in soils also has another very important function: crop nutrition. Last year, researchers from CIMMYT and the Nature Conservancy found that wheat grown on soils rich in organic matter had more essential nutrients like zinc and protein.
However, increasing levels of organic carbon in the soil can be costly in the short term, so farmers need to see improvements in the performance of their soils as a result of their efforts.
Quantifying soil carbon
That’s where a global soil information system comes in. By integrating empirical models, expanded measurement and monitoring networks, remote sensing and crowdsourced management data, SOC stocks can be assessed efficiently and reliably. Farmers and policy makers would get a clear picture of how much soil organic carbon is increasing and at what rate.
The global soil information system would work by pulling different sources of existing information together to provide a comprehensive account of soil organic carbon stocks worldwide.
As SOC content can vary over time, an important component of the system would involve using monitoring networks at precise locations which can then be resampled regularly. Alongside this information, empirical models would be used to predict SOC changes based on already observed results from lab- and field-based experiments, and to predict the impacts of different soil and climate conditions. Remote sensing data can provide information on land cover, crop species and land management practices at a very low cost, to supplement and verify management activity data reported by land users.
The international team of scientists pointed out that greater coordination and transparency among scientists, remote sensing specialists and land managers is crucial to the success of a global soil information system.
Incentivizing carbon sequestration among land managers is no mean task. The authors argue that existing approaches like direct compensation to farmers for CO2 removal and storage, government subsidies such as the European Union’s Common Agricultural Policy (CAP) and the option of earning a premium price for producing sustainable agricultural products, need a reliable carbon accounting system to ensure their success. A global soil information system might just hold the key.
This study was made possible through the support provided by the TomKat Foundation. Additional support was provided by the NASA Harvest Consortium (www.nasaharvest.org), a multi-disciplinary program that empowers informed agricultural decisions through the use of Earth observations.

CIMMYT’s projects in Latin America feature in a new report that aims to help countries use data to design public policies and projects that help achieve the Sustainable Development Goals (SDGs) by 2030.
The Counting on The World to Act report was released on September 23, 2019, by the Sustainable Development Solutions Network (SDSN) and the Thematic Research Network on Data and Statistics (TReNDS) during the 74th session of the United Nations General Assembly (UNGA 74) in New York City.
The report describes CIMMYT’s data management systems and tools as examples of “frontier technologies” for data gathering, management and analysis that effectively contribute to sustainable farming in Colombia, Guatemala and Mexico.
“As part of the data revolution, efficiencies are being derived from lower-tech approaches such as using citizen-generated data and smartphones to speed up existing survey-based approaches,” reads the introduction to CIMMYT’s sidebar story in Chapter 4, Incentives for Innovation.
The MasAgro Electronic Log that field technicians use to monitor crop cycles and management practices, and the AgroTutor application that offers farmers more specific and timely recommendations are some of the new affordable tools for data management that CIMMYT is successfully implementing in Latin America.
In July 2019 ICIMOD, along with its partners and the International Maize and Wheat Improvement Centre in Mexico, launched a web-based Regional Drought Monitoring and Outlook System for South Asia – an integrated information platform linking weather and climate data with agriculture practices in South Asia. The system provides multiple indices for droughts and seasonal weather outlooks, besides maps and baseline. Read more here.

Using the full wheat genome map published in 2018, combined with data from field testing of wheat breeding lines in multiple countries, an international team of scientists has identified significant new chromosomal regions for wheat yield and disease resistance and created a freely-available collection of genetic information and markers for more than 40,000 wheat lines.
Reported today in Nature Genetics, the results will speed up global efforts to breed more productive and climate-resilient varieties of bread wheat, a critical crop for world food security that is under threat from rising temperatures, rapidly-evolving fungal pathogens, and more frequent droughts, according to Philomin Juliana, wheat scientist at the International Maize and Wheat Improvement Center (CIMMYT) and first author of the new study.
“This work directly connects the wheat genome reference map with wheat lines and extensive field data from CIMMYT’s global wheat breeding network,” said Juliana. “That network in turn links to over 200 breeding programs and research centers worldwide and contributes to yield and other key traits in varieties sown on nearly half the world’s wheat lands.”
The staple food for more than 2.5 billion people, wheat provides 20% of human dietary calories and protein worldwide and is critical for the nutrition and food security of hundreds of millions of poor persons in regions such as North Africa and South Asia.
“Farmers and societies today face new challenges to feed rising and rapidly-urbanizing populations, and wheat epitomizes the issues,” said Ravi Singh, CIMMYT wheat breeder and corresponding author of the study. “Higher temperatures are holding back yields in major wheat-growing areas, extreme weather events are common, crop diseases are spreading and becoming more virulent, and soil and water are being depleted.”
Juliana said the study results help pave the way to apply genomic selection, an approach that has transformed dairy cow husbandry, for more efficient wheat breeding.
“Molecular markers are getting cheaper to use; meanwhile, it’s very costly to do field testing and selection involving many thousands of wheat plants over successive generations,” Juliana said. “Genome-wide marker-based selection can help breeders to precisely identify good lines in early breeding generations and to test plantlets in greenhouses, thereby complementing and streamlining field testing.”
The new study found that genomic selection could be particularly effective in breeding for wheat end-use quality and for resistance to stem rust disease, whose causal pathogen has been evolving and spreading in the form of highly-virulent new races.
The new study also documents the effectiveness of the global public breeding efforts by CIMMYT and partners, showing that improved wheat varieties from this work have accumulated multiple gene variants that favor higher yields, according to Hans-Joachim Braun, director of CIMMYT’s global wheat program.
“This international collaboration, which is the world’s largest publicly-funded wheat breeding program, benefits farmers worldwide and offers high-quality wheat lines that are released directly to farmers in countries, such as Afghanistan, that are unable to run a full-fledged wheat breeding program,” Braun explained.
The study results are expected to support future gene discovery, molecular breeding, and gene editing in wheat, Braun said.
Together with more resource-efficient cropping systems, high-yielding and climate-resilient wheat varieties will constitute a key component of the sustainable intensification of food production described in Strategy 3 of the recent EAT-Lancet Commission recommendations to transform the global food system. Large-scale genomics will play a key role in developing these varieties and staying ahead of climate- and disease-related threats to food security.
Funders of this work include USAID’s Feed the Future Innovation Lab for Applied Wheat Genomics. Contributing to the research described are research teams engaged in wheat improvement at CIMMYT, and the lab of Jesse Poland, Associate Professor at Kansas State University and Director of the USAID Applied Wheat Genomics Innovation Lab.

How to track adoption and assess the impact of maize and wheat varieties? Some of the methods used until now, like farmers’ recall surveys, have various limitations. In addition to relying exclusively on people’s memory and subjectivity, they are difficult to replicate and prone to errors.
DNA fingerprinting, on the other hand, allows objective evaluation and is considered the “gold standard” method for adoption and impact assessments.
It consists of a chemical test that shows the genetic makeup of living things, by separating strands of DNA and revealing the unique parts of their genome. The results show up as a pattern of stripes that can be matched against other samples.
This technique is extremely helpful in tracking crop varieties and monitoring their adoption. It can be used to assess the impact of research-for-development investments, guide breeding and seed system strategies, implement the intellectual property rights of breeders, assess the use of crop genetic resources, and informing policy.
On June 25, 2019, the International Maize and Wheat Improvement Center (CIMMYT) held a half-day workshop in Addis Ababa to discuss the use and application of DNA fingerprinting in Ethiopia for the tracking of crop varieties.
High-level government officials and major players in the agricultural sector were interested in learning more about the policy implications of this tool and how to mainstream its use.

Introducing DNA fingerprinting in Ethiopia
The main DNA fingerprinting project in Ethiopia has been in operation since January 2016, focusing on the country’s two major staple crops: wheat and maize. The project covers the Amhara, Oromia, SNNPR, and Tigray regions, which together account for 92% and 79% of the national wheat and maize production.
The Bill & Melinda Gates Foundation has funded the project, which was jointly implemented by CIMMYT, the Ethiopian Institute of Agricultural Research (EIAR), Ethiopia’s Central Statistical Agency (CSA) and Diversity Arrays Technology (DArT).
The main objective of the project was to generate a knowledge base for the practical use of DNA fingerprinting, to mainstream the use of this technology, and to offer policy options and recommendations.
CIMMYT scientists Dave Hodson (left), Bekele Abeyo (center) and Sarah Hearne participated in the workshop.
Better monitoring for wheat self-sufficiency
At the workshop, researchers presented two policy briefs specific to Ethiopia: one focusing on policy implications of DNA fingerprinting for tracking bread wheat varieties and another one on how to revitalize the durum wheat sub-sector.
Speaking at the workshop, Eyasu Abraha, Minister of Agriculture and Natural Resources, noted that the government planned to achieve wheat grain self-sufficiency in the next few years by increasing wheat productivity in the highlands and expanding wheat production to the lowlands through irrigation. In this regard, improved crop variety development and dissemination is one of the key elements to increase agricultural productivity and improve the livelihood of millions of smallholder farmers.
According to Abraha, more than 130 wheat varieties have been released or registered in Ethiopia since the late 1960s, in collaboration with international research organizations. Public and private seed enterprises have multiplied and distributed these varieties to reach smallholder farmers.
Even though adoption studies have been conducted, there is still a strong need for more accurate and wider studies. In addition to tracking adoption and demand, using DNA fingerprinting could help understand the distribution of varieties across space and time.
This year’s African Green Revolution Forum (AGRF), which took place from September 3-6, 2019 in Accra, Ghana, focused on the potential of digital agriculture to transform African agriculture through innovations such as precision agriculture solutions for smallholder farmers, access to mobile financial services, data-driven agriculture, and ICT-enabled extension.
Committed to a digital transformation of African agricultural that benefits many, not a few.
Despite its importance of the continental economy and untapped resources, African farming sector is still dominated by ageing smallholders cultivating few acres of cropland, using not much inputs and lagging far behind productivity world standards.
Many experts believe digital agriculture could help African agriculture leapfrog to overcome its geographical, social and economic bottlenecks, bringing successful technologies to scale faster, and market opportunities even for remote smallholders. Some countries like Ghana or Kenya are becoming digital hubs for agritech-savvy young entrepreneurs along the food value chains, from drone for Ag, linking farmers to the marketplace, or offering mobile mechanization or financial services.
Large initiatives were announced to foster this growth potential, in particular towards the youth in agriculture, like the Mastercard Foundation’s commitment to invest $500 million to support for young agripreneurs within its Young Africa Works initiative, and the World Bank’s One Million Farmer platform in Kenya.
Improving smallholders’ resilience through digital innovations
The millions of African rainfed farmers are in a risky business, from rising climate shocks to emerging pests and diseases like the invasive fall armyworm or the maize lethal necrosis. CIMMYT Director General Martin Kropff highlighted the importance of digital tools to predict these risks through smart, scalable early warning systems like the award-winning diagnostic tool Marple that helps map wheat rust outbreaks. Researchers can also better predict the farms’ responses to these risks through accurate modelling. They can for instance better assess the potential yield benefits of drought and heat tolerance under different climate change scenarios.
CIMMYT crop breeders use tablet-based disease scoring applications and test new imagery and high-tech sensors for more accurate and cost-effective data collection. Kropff underlined the key role digital tools play to speed up science breakthroughs and impact delivery at the farm level.
Tailored advice for farmers and policy-makers to enable sustainable intensification
“The future is no longer where it used to be. Farmers’ reality has become even more unpredictable,” said Enock Chikava, deputy director, agricultural development at the Bill & Melinda Gates foundation during a vivid debate on how to reshape the future agronomic research so it delivers more site-specific and responsive advice.
Much of the agronomy work within the region remains fragmented across research institutes, commodities and projects, and struggles to go beyond blanket recommendations that are most of the time not adapted to local farming conditions.
However, there is a fast-growing wealth of georeferenced data that can describe the diverse farming landscapes and socio-economic context of each African smallholder farmer. The starting point to exploit these data and get the right solutions for each farmer is to ask the right questions.
Moderated by Samuel Gameda, CIMMYT soil scientist, who shared the lessons from the Taking Maize Agronomy to Scale (TAMASA) project, this session on Agronomy at Scale discussed what public information goods like crop yield prediction maps or extension apps, such as the maize variety selector, would be the most useful for farmers and large-scale agronomic initiatives to trigger this much needed sustainable intensification of millions of African smallholdings. What investments would make a difference to scale the use of these new decision-support tools?
“Agronomic research must be carried out from a broader perspective of large-scale relevance and application. It is also more and more a joint effort and responsibility between smallholder farmers, the research community and public and private sectors, with each component playing specific and interacting roles. The current era of powerful and accessible ICT tools and big data analytics make this much more feasible and should be incorporated to enable precision agronomy for all, this is my take home message,” said Gameda.
“This data revolution will only work if we invest in research data quality and data management,” stressed Bram Govaerts, CIMMYT’s Integrated Development Program director. “That will generate better evidence for decision-makers to guide impact investment plans, deciding on which technology e.g. a new drought-tolerant crop variety and put the money in the right leveraging point,” Govaerts concluded.
The largest forum on African agriculture, AGRF 2019 gathered more than 2,200 delegates and high-level dignitaries, from heads of State and government officials to leaders of global and regional development institutions; top agri-food businesses and local entrepreneurs; financial institutions; mobile network operators and tech leaders, as well as lead representatives of farmer organizations.
