The G20 Foreign Ministers’ meeting held on July 7-8 in Bali saw Chinese State Councillor and Foreign Minister, Wang Yi, highlight support for CGIAR as part of a proposed cooperation initiative to boost global food security.
Foreign Minister Wang Yi highlighted the need to help CGIAR increase innovation and build cooperation on agricultural science and technology among countries. Addressing the meeting, Wang said the food and energy sectors are crucial for the healthy performance of the world economy and the effective implementation of the UN 2030 Agenda for Sustainable Development.
His statement was made shortly before the signing of Letters of Intent for Cooperation between the Chinese Academy of Agricultural Sciences (CAAS) and two CGIAR Research Centers, the International Maize and Wheat Improvement Center (CIMMYT) and the International Rice Research Institute (IRRI).
CIMMYT, IRRI and CAAS intend to establish a joint Center in Hainan to address global food security through advances in wheat and rice breeding. The collaboration aims to enhance the environmental sustainability of rice and wheat based agri-food systems, promote biodiversity conservation, combat climate change, and improve the health and welfare of growers and consumers.
Jean Balié, Regional Director, South East Asia and Pacific, CGIAR, and Director General of IRRI said: “Our new agreement solidifies and updates a longstanding and fruitful partnership. Today we face a different and growing set of challenges to our food, land and water systems, and we welcome the opportunity to strengthen knowledge and information exchange from across CGIAR that will contribute to a transformation of global food, land and water systems.”
CIMMYT Director General, Bram Govaerts added: “This state-of-the-art breeding center will help us develop and deploy the new nutritious, high-yielding and resilient varieties that Asian farmers need to feed and nurture the most populous region of the world sustainably or within planetary boundaries.”
In three decades of collaboration, CAAS and CGIAR have cooperated on germplasm exchange, breeding new varieties of crops, and providing opportunities for staff collaboration, development and training.
In wheat research, the partnership has added as much as 10.7 million tons of grain – worth $3.4 billion – to China’s national wheat output. Additionally,eight CIMMYTscientists have won the Chinese Friendship Award – the highest award for foreign experts who have made outstanding contributions to China’s economic and social progress.
A reaffirmation of Chinese support for CGIAR comes on a tide of growing recognition that more investment is needed to tackle hunger.
Earlier in the year the G7 Foreign Ministers’ Communiqué underlined the urgent need to address risk in global food systems citing this as a top foreign policy objective. At the same time, the G7 Agricultural Ministers Communiqué cautioned that slowing down work to address longer term goals of food systems transformation, in order to address short term food crises, will have negative consequences in the medium and long term. In this context CGIAR’s System Board Chair, Marco Ferroni, recently highlighted the need for world leaders to look at the big picture to solve the food crisis.

“Now more than ever, we need to build greater resilience across our global food system,” said Alison Bentley, Director of Global Wheat Program at the International Maize and Wheat Improvement Center (CIMMYT), to introduce her part of a joint seminar between CIMMYT and WorldFish. The two CGIAR research centers may appear to have different focuses, but the pairing draws attention to many opportunities for intra-CGIAR collaboration to address the looming global food crisis.
Beginning with Ahmed Nasr-Allah, Country Director (Egypt) at WorldFish, the presentation explored Integrated Agriculture and Aquaculture (IAA) systems for food security. Over the coming decades, population growth and increased scarcity of water pose a challenge for food production and agriculture, so water efficiency needs to be maximized.
Nasr-Allah explained that wheat nutrients improve soil quality, which in turn positively impacts fish quality when using water running off growing crops. He gave an example of a farmer who allocated more space on his farm to irrigate and store water and fish, which enabled him to produce higher crop yields. Further research between WorldFish and CIMMYT in this area could be examining nutrient flow from the fish system to the crop system.
Second to present was Bentley, looking at shock-proofing wheat to build future resilience. “It’s important we understand where the risks lie in our global system so we can respond to shocks,” she explained, citing data on global import dependency on Ukrainian and Russian wheat. She went on to describe potential solutions to combat the predicted yield decrease in wheat in the Global South, including substituting a proportion of wheat flour with other under-utilized crops in products, without impacting flour quality or consumer evaluation.
Linking to WorldFish’s work, Bentley highlighted the need to use water more effectively by combining new varieties with enhanced mechanization options to improve crop management, and the potential of optimizing individual components in fish and wheat rotations that could then be combined for greater impact.
The third session was with WorldFish Scientist Sarah Freed, who discussed designing integrated production practices to meet diverse needs. She invited event attendees to consider whether the lessons learnt from challenges in rice growing areas, such as climate change, poverty, food and nutrition insecurity, and increased demand, could be applicable solutions to problems in wheat growing areas.
Using biophysical and sociocultural insights from rice-fish innovations as an example, she listed five recommendations for design: identify objectives; identify a range of production options; use a co-design process; implement fit-for-purpose design and evaluation; and enable adaptation. Of particular interest was the co-design process with people who are involved at all levels, from landowners to rice farmers to laborers, so that the design benefits a variety of stakeholders. Freed also noted that decisions taken for economic reasons, such as extending the shrimp season, can lead to increased soil salinity, which means the ground can no longer incorporate diverse crops.
All three speakers concluded the event by acknowledging the potential in combining their research areas to determine and implement food security solutions.
Analysis of evidence by scientists of the International Maize and Wheat Improvement Center (CIMMYT) and CGIAR concludes that the scientific risks of genome editing are similar to those of traditional breeding: all new varieties, however developed, need to be tested for agronomic performance in a range of environments.
Social risks are mainly that these powerful technologies may be rendered inaccessible to less-commercial crops and farmers if intellectual property (IP) and regulatory policies make them expensive or difficult to use.
Genome editing has demonstrated potential to contribute to food security, improved nutrition, and value addition for farmers and consumers.
Many countries are still uncertain about whether to grow, or if and how to regulate genome-edited crop varieties. The Court of Justice of the European Union (CJEU) has stated that genome-edited crops should be considered as transgenics in the EU for regulatory purposes, a decision that could limit their use in Africa. On the other hand, several countries, including USA, Canada, Brazil, Colombia, Argentina, Chile, Kenya, Nigeria, Israel, India, and Japan have determined that genome-edited crops should not be regulated like transgenics if they do not contain foreign DNA.
Policies should enable choice and avoid the risk that genome editing technologies for crops benefit only those who can pay premium price. Smallholder farmers should have equal access to advanced technologies, should they wish to use them, as well as relevant and objective information about their value and how to use them.
The Chinese Academy of Agricultural Sciences (CAAS), the International Maize and Wheat Improvement Center (CIMMYT) and the International Rice Research Institute (IRRI) are establishing a breeding center in Sanya, Hainan Province, China.
The international cooperation will be conducive to the exploration and utilization of germplasm resources of the research organizations, biological breeding research, technical training, and the innovation of the global seed industry.

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

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

“This was an incredibly useful workshop for us,” said PC Sharma, Director of ICAR-CSSRI. “This represents a new way of thinking about how to approach crop rotations and production. Having the help of farmers and colleagues in the nutrition community to design our research means we can address multiple issues in one research program. This increases the value of our research and spreads the benefits wider.”
To conclude the workshops, groups presented on their field visits and selected crop rotations and management practices as part of agronomic trial design for nutrition-sensitive and environmentally efficient cropping systems, including consideration of implementation and data collection.
In just a decade, CRISPR has become one of the most celebrated inventions in modern biology. It is swiftly changing how medical researchers study diseases: Cancer biologists are using the method to discover hidden vulnerabilities of tumor cells. Doctors are using CRISPR to edit genes that cause hereditary diseases.
But CRISPR’s influence extends far beyond medicine. Evolutionary biologists are using the technology to study Neanderthal brains and to investigate how our ape ancestors lost their tails. Plant biologists have edited seeds to produce crops with new vitamins or with the ability to withstand diseases. Some of them may reach supermarket shelves in the next few years.
We report with great sadness the death of Ephrame Havazvidi, who passed away on May 14, 2022.
Havazvidi was one of the world’s pioneering wheat breeders. He served on the Independent Steering Committee of the CGIAR Research Program on Wheat (WHEAT) from 2015 to 2021. He was a renowned seed and crop scientist of the wheat industry in Zimbabwe and the wider region and a frequent expert contributor to projects of the International Maize and Wheat Improvement Center (CIMMYT) in the region.
WHEAT Independent Steering Committee chair John Porter said, “Ephrame will no longer be gracing us with his big beaming smile, bright eyes and gorgeous laughter. Ephrame was a unique person and did so much to promote food security in Zimbabwe. He always supported the WHEAT Independent Steering Committee and shared his pan-African perspective on wheat-based food security. It was a great pleasure to have had him on our team.”
“Ephrame was not only an outstanding partner of both CIMMYT’s maize and wheat programs, especially when it came to promoting drought-tolerant varieties, but first and foremost a lovely human being,” said Prasanna Boddupalli, director of CIMMYT’s Global Maize Program.
Born in Masvingo District on 22 September 1954, Havazvidi held Doctor of Philosophy, Master of Philosophy and Bachelor’s degrees, all obtained from the University of Zimbabwe.
Before joining the University of Zimbabwe (then University of Rhodesia) in 1974 to 1976, he was among the top academic achievers at Berejena Mission in Chibi and Goromonzi High School for his Cambridge GCE “O” and “A” level studies respectively. Havazvidi also completed a year-long Executive Development program at the University of Zimbabwe and attended several management developments programs that include SMI.
Havazvidi began his career as a cotton agronomist at the Cotton Research Institute under the Zimbabwe Department of Research and Specialist Services in the then Ministry of Agriculture in Kadoma in 1977. He then joined Seed Co Limited, then Seed Coop, as a seed production research agronomist in 1980, where he pioneered research on maize seed production. Shortly thereafter, he became Seed Co’s principal wheat breeder between 1982 and 2011; as Seed Co breeder, Ephrame released 28 high-yielding wheat varieties that improved farmer productivity in Southern African countries. The varieties for irrigated areas helped to reduce Zimbabwe’s import burden at the time.
He also developed several high high-yielding maize inbred lines for Seed Co. Havazvidi has written several journal articles and presented at several high-level symposia and conferences locally and globally including for the CIMMYT-led Drought Tolerant Maize for Africa (DTMA), Water Efficient Maize for Africa (WEMA), Improved Maize for African Soils (IMAS), and HarvestPlus Pro Vitamin A projects.
In 2020, he was recognized as one of 20 most influential plant breeders by the Southern African Plant Breeding Association (SAPBA).
Hazvidi is survived by his wife Elizabeth, four children — Charles, Happines, Kennedy and Rumbi – and grandchildren.
Firpo was born in Montevideo, Uruguay, where he received a BSc degree as an agronomy engineer in 1997 from the University of the Republic, College of Agronomy. His PhD degree in 2008 was from the Department of Plant Pathology at the University of Minnesota (UMN). He began his career as a postdoctoral research associate with the Department of Plant Pathology and the USDA-ARS Cereal Disease Lab, and then became a research assistant professor in the Department of Plant Pathology at UMN in 2017.
Firpo has been a vital member in the global cereal rust pathology community and contributed substantially to the fight against Ug99 and other virulent wheat stem rust races that have re-emerged around the world and pose serious threats to food security. Firpo’s contributions are not only within the realm of research of great impact, but also include training 79 scientists and facilitating the establishment of a world-class research group in Ethiopia. He has worked to improve international germplasm screening in Ethiopia. As a postdoctoral research associate, Firpo’s first assignment was to search for new sources of resistance to Ug99 in durum wheat, used for pasta, and related tetraploid wheat lines. That project took him to Ethiopia, where an international Ug99-screening nursery for durum wheat was established at Debre Zeit Research Center. He worked closely with researchers from the Ethiopian Institute of Agricultural Research (EIAR) and the International Maize and Wheat Research Center (CIMMYT) to improve the methodologies for screening and to provide hands-on training to researchers managing the international screening nursery. During a period of 10 years (from 2009 to 2019), he traveled to Ethiopia 21 times to evaluate stem rust reactions of US and international durum wheat germplasm and completed the screening of the entire durum collection (more than 8,000 accessions) from the USDA National Small Grains Collection.
Firpo’s research on sources and genetics of stem rust resistance led to discoveries of valuable genetic resistance in durum and other relatives of wheat. These sources of resistance have provided the needed diversity to ensure the development and sustainability of durable stem rust resistance.
With frequent epidemics and severe yield losses caused by stem rust in eastern Africa, establishing a functional rust pathology laboratory to support international screening, as well as to monitor and detect new virulences in the pathogen population, became a high priority for the international wheat research community. Utilizing the onground opportunities in Ethiopia, Firpo and his colleagues at the CDL and UMN enthusiastically participated in building up the rust pathology lab at the Ambo Plant Protection Center of EIAR. Firpo traveled to Ambo 11 times to provide hands-on training to staff and to develop cereal rust protocols to suit local conditions. He worked closely with colleagues at CDL, EIAR, and CIMMYT to secure and upgrade facilities, equipment and supplies to a standard that ensures reliable rust work will be carried out. As a result, the rust pathology lab at the Ambo Center became the only laboratory in eastern Africa, and one of a handful in the world, that can conduct high-quality race analysis of wheat stem rust samples and provide vital and necessary support for breeding global wheat varieties for rust resistance. Currently, the laboratory is playing a critical role in the global surveillance of the stem rust pathogen and supports wheat breeding efforts led by EIAR, CIMMYT, and the USDA.
Firpo has been passionate in supporting capacity building of human resources in Ethiopia and elsewhere. He has been eager to share his knowledge whenever he encounters an opportunity to do so. In addition to the direct training of the staff at the Ambo Center, Firpo accepted invitations to provide training lectures and hands-on field- and greenhouse-based workshops on rust pathology at three research centers in Ethiopia. He prepared training materials, delivered a total of 12 lectures and 10 practical sessions in three Ethiopia national workshops in 2014, 2015, and 2017. These workshops enhanced human resource development and technical capacity in Ethiopia in cereal rust pathology; participants included a total of 64 junior scientists and technical staff from nationwide research centers. Beyond Ethiopia, he was responsible for developing and implementing a six-week training program in cereal rust prevention and control for international scientists. This training program, under the aegis of the Stakman-Borlaug Center for Sustainable Plant Health in the Department of Plant Pathology, University of Minnesota, provided an experiential learning opportunity for international scientists interested in acquiring knowledge and practical skills in all facets of working with cereal rusts. The program trained 15 rust pathologists and wheat scientists from Ethiopia, Kenya, Pakistan, Nepal, Bhutan, Georgia, and Kyrgyzstan, ranging from promising young scientists selected by the USDA as Borlaug Fellows to principal and senior scientists in their respective countries. Many of these trainees have become vital partners in the global surveillance network for cereal rusts.
Working in collaboration with CDL and international scientists, Firpo has been closely involved in global surveillance of the stem rust pathogen, spurred by monitoring the movements of, and detecting, new variants in the Ug99 race group. Since 2009, he and the team at the CDL have analyzed 2,500 stem rust samples from 22 countries, described over 35 new races, and identified significant virulence combinations that overcome stem rust resistance genes widely deployed in global wheat varieties. Among the most significant discoveries were the identification of active sexual populations of the stem rust pathogen in Kazakhstan, Georgia, Germany, and Spain that have unprecedented virulence and genetic diversities. More than 320 new virulent types (or races) were identified from these sexual populations. Evolution in these populations will present continued challenges to wheat breeding. Research in race analysis has provided valuable pathogen isolates that are used to evaluate breeding germplasm to select for resistant wheat varieties and to identify novel sources of stem rust resistance.

Representatives from the National Association of State Departments of Agriculture (NASDA) of the United States visited the global headquarters of the International Maize and Wheat Improvement Center (CIMMYT) on May 19, 2022. Ted McKinney, NASDA’s Chief Executive Officer, was joined by RJ Karney, Senior Director of Public Policy, and John Goldberg, consultant and partner at The Normandy Group.
“I wish the world could all understand what you do here. This is just fantastic,” said McKinney after seeing the broad range of work conducted at CIMMYT.
NASDA’s tour of CIMMYT’s global headquarters in Texcoco, Mexico, included visits to the museum, the maize and wheat genebanks, the greenhouse, the bioscience complex, the wheat quality laboratory and the experimental station.
In each location, the visitors met with CIMMYT representatives who provided an overview of their research areas. Discussions ranged from the importance of preserving disease resistance in wheat in order to conduct experiments, the process for using DNA to inform breeding programs, and the assessment process for wheat grain. NASDA’s representatives also gained an understanding of how CIMMYT connects experiments with the needs of farmers, ensuring that scientific progress is translated into real-life solutions.

For a decade, scientists at the International Maize and Wheat Improvement Center (CIMMYT) have been at the forefront of a multidisciplinary and multi-institutional effort to contain and effectively manage maize lethal necrosis (MLN) disease in Africa.
The manual is relevant to stakeholders in countries where MLN is already present, and also aims to offer technical tips to “‘high-risk’ countries globally for proactive implementation of practices that can possibly prevent the incursion and spread of the disease,” writes B.M. Prasanna, director of CIMMYT’s Global Maize Program and MAIZE, in the foreword.
“While intensive multi-disciplinary and multi-institutional efforts over the past decade have helped in containing the spread and impact of MLN in sub-Saharan Africa, we cannot afford to be complacent. We need to continue our efforts to safeguard crops like maize from devastating diseases and insect-pests, and to protect the food security and livelihoods of millions of smallholders,” says Prasanna, who is presently leading the OneCGIAR Plant Health Initiative Design Team.

Global food prices were already increasing when the world’s wheat supply came under extra pressure, due to Russia’s war on Ukraine. We don’t know whether the farmers who have made Ukraine the fifth-largest exporter of wheat will produce anything in 2022.
Food security is bound to fall, with the greatest impact to be felt by those most vulnerable first. Ukrainians are bearing the worst of it, of course, but the fallout from Vladimir Putin’s cruelty will affect us all.
The problem would be much worse if a remarkable group of scientists had not dedicated themselves in the last century to the improvement of agriculture, in work that continues today and promises to make the future a little more hopeful.
My family witnessed the work of these scientists up close. Our farm is in the state of Tlaxcala, in the highlands east of Mexico City. We grow corn, barley, sunflower, and triticale, which is a hybrid of wheat and rye.
During the 1950s and 1960s, Norman Borlaug brought teams of agronomists to our region as he worked to improve wheat’s germplasm. I wasn’t born at that time, so I couldn’t meet Dr. Borlaug at our farm, but he came many times across several summers. I’ve heard the stories: As my father worked with Borlaug in the fields, growing the seeds that would help Borlaug produce a better kind of wheat, my mother made sure that our house was in order so that Borlaug and his companions had proper accommodations.
Today, of course, Dr. Borlaug is a legend: In 1970, he won the Nobel Peace Prize. Hailed as “the father of the Green Revolution,” he arguably saved hundreds of millions of lives through science-based improvements to the wheat germplasm.
The result is that wheat farmers around the world grow a lot stronger, healthier wheat today. No matter where we live, we’re better able to deal with problems of scarcity.
Drought, disease, and war still possess the horrible potential to inflict suffering, but we’re in fact much more capable of dealing with them because of what Dr. Borlaug and his fellow researchers accomplished decades ago.
Their work continues today at the International Wheat and Maize Improvement Center, also known as CIMMYT (in its Spanish acronym). Founded by the Mexican government and the Rockefeller Foundation, this non-profit group devoted itself to improving the productivity of Mexican farmers. It became the institutional home of Borlaug, whose work was so successful it transformed agriculture not just in Mexico but around the world.
Mexican farmers gained from its work, and so did wheat farmers in India, Pakistan, and elsewhere. In fact, everybody wins: The world has much more wheat today because of Borlaug and CIMMYT.
I’m a special beneficiary, and not just because of my family’s historical connection to CIMMYT. I live within driving distance of CIMMYT’s headquarters, which is a sanctuary of knowledge. It enjoys an amazing history, but also holds a promising future: It remains a resource for improvements in agriculture.
As an agronomist, I always believed that science is a status improver. Because of CIMMYT, I’m a better farmer today than I was just a few years ago, and I’ll be even better in the years ahead.
CIMMYT’s Karim Ammar taught me about triticale, which is producing great results on my farm. As science has progressed and with the conjunction of science and technology, farmers are able to improve productivity and have better soils. Today, Bram Govaerts, who is now CIMMYT’s Director General, introduced me to the value of no-till, which is making my farm both more productive and more sustainable.
Dr. Borlaug’s dying words were “take it to the farmers.” That’s exactly what his successors at CIMMYT are doing. They’re adapting cutting-edge technologies to agriculture. The best part, though, is that they don’t keep their knowledge locked up in labs. They share what they learn with farmers like me, who can apply them to the practical work of food production.
Agriculture will face plenty of tests in the 21st century. The world’s population continues to grow, but our arable land doesn’t increase with it. That means we must continue to produce more food from the farms we already have. At the same time, we must contend with the threat of climate change and make our methods more sustainable, which means preserving biodiversity, conserving water, and kidnapping carbon.
Amid these challenges, Russia’s invasion of Ukraine, a globally important farming nation, is adding stress to the challenge of global food security. As we watch a country and its innocent people suffer, we aren’t thinking much about wheat germplasms—but we should be grateful that CIMMYT’s agronomists have made us all a little more resilient.
In nature, plants are simultaneously exposed to a complex system of biotic and abiotic stresses that limit crop yield. The cereal cyst nematode Heterodera filipjevi and dryland crown rot, caused by Fusarium, are important diseases facing cereal production around the world that cause significant yield loss. Yield loss accelerates when those diseases coexist with other abiotic stresses, such as drought.
Hexaploid bread wheat (Triticum aestivum L.) is an essential staple food for a large part of the world’s population, covering around 20% of daily caloric intake in the human diet, with global production at about 670.8 million tons per year, produced over 215.4 million hectares of land worldwide. Therefore, the program studying soil-borne pathogens at the International Maize and Wheat Improvement Center (CIMMYT)’s Turkey office initiated a study to investigate the effect of soil borne diseases (H. filipjevi and Fusarium culmorum) individually and in combination with drought on some morphological and physiological traits in wheat germplasm with different genetic tolerances to the three studied factors.
In this study, yield components included thousand kernel weight, spike weight, seed per spike and total grain yield. Morphological parameters, including plant height, final plant number (seedling emergence), relative water content, leaf chlorophyll content, H. filipjevi cyst number and presence of crown rot, were studied under greenhouse conditions in Turkey.
The main findings of the study showed that the interaction among water stress, F. culmorum and H. filipjevi increased the damage on the wheat parameters studied when compared with each stress applied alone. One of the most significant damages was seen in high seedling mortality under the three combined stresses (56% seedling death rate), which indicates the damage on wheat yield might occur at the seedling stage rather than later stages. This reduces plant density per area, which was ultimately responsible for low grain yield produced. The known dryland disease, crown rot, caused by F. culmorum, was significantly pronounced under water-stressed conditions.
In all studied parameters, the lowest damage was found among the resistant cultivars to biotic or abiotic stresses. This underscores the importance of wheat breeding programs to develop resistant germplasm, and reminds farmers to replace their old, susceptible varieties with new, resistant ones.
Based on our intensive experience in the CWANA region, most wheat growers basically do not recognize soil borne pathogens as a problem. In fact, most of them do not know that what nematode or soil fungal species are in their fields affecting yield. The term “hidden enemy” perfectly applies to the problems in the region and beyond. Integrated pest management (IPM) is, however, not practiced in the entire region and soil borne pathogen-induced yield losses are simply accepted.
We can conclude from this study that yield reduction in wheat due to soil borne pathogens could be lessened by improving and understanding the concept of IPM in the region where the practice of winter mono-culturing of wheat is the norm. Management of cereal soil-borne pathogens, especially cereal cyst nematode and crown rot, could involve an integrated approach that includes crop rotation, genetic resistance, crop nutrition and appropriate water supply.

A five-year partnership being launched by the Innovative Genomics Institute (IGI)—a non-profit founded by Nobel Laureate Jennifer Doudna—and CGIAR, the world’s largest publicly-funded agricultural research partnership, will harness the power of science to help millions of people overcome poverty, hunger and malnutrition.
One in four people globally, and rising, are unable to afford a healthy diet. COVID-19 has exacerbated this trend by disrupting food production and distribution, driving up by 20 percent the number of people threatened by hunger in 2020. The pandemic is unfolding amidst an environmental and climate crisis which is undermining food production and our ability to nourish the world.
But global consensus is building for urgent action. At the COP26 meetings in November, 45 nations committed to shifting to more sustainable ways of farming and accelerate the deployment of green innovations. Similarly, in late September, many government representatives at the United Nations Food Systems Summit committed to accelerating the transformation of how we grow, transport, process, and consume food. Recognizing the centrality of science and innovation for driving that transformation, United Nations Secretary-General António Guterres called on the world to scale public and private investment in research for food.
According to Barbara Wells, Global Director for Genetic Innovation at CGIAR: “World-class science is vital for facilitating farmer adaptation and mitigating our food system’s contribution to climate change. Plant-breeding innovations can help ramp up food production while making farms more climate resilient, profitable and environmentally friendly”.
“Technologies such as gene editing, which enable scientists to make targeted changes to a crop’s DNA, can accelerate the development of more disease-resistant, water-efficient varieties that can improve food production and nutrition in areas that are especially vulnerable to climate change,” Dr. Wells explained.
CGIAR has produced and promoted innovations that are boosting the sustainable production of nutritious food in Africa, Asia and Latin America. Over the past five decades, CGIAR scientists and national partners have developed and disseminated robust and highly productive crop varieties and livestock breeds tailored to the needs of local men and women. Those innovations have helped hundreds of millions of people across the Global South overcome hunger and poverty.
The IGI is a collaboration of the University of California, Berkeley and the University of California, San Francisco with a mission to develop revolutionary genome-editing tools that enable affordable and accessible solutions in human health, climate, and agriculture. The IGI’s Climate & Sustainable Agriculture program focuses on developing crops that are resistant to pests and diseases, resilient to a changing climate, and less dependent on farmer inputs. Whereas the IGI is a pioneer in applied genomic research, CGIAR focuses on translating discoveries into improved crop varieties and cropping systems. This partnership provides an accelerated pipeline from upstream innovation to real-world impact.
“The IGI is testing technologies with great potential to benefit people in the countries where CGIAR is active, such as a way of removing the cyanide found in cassava—a staple upon which nearly a billion people depend—and fighting diseases in economically important crops like wheat, rice and bananas,” said Brian Staskawicz, the IGI Director of Sustainable Agriculture.
“The IGI is also pioneering new ways to reduce methane emissions from rice farming, which accounts for 2.5 percent of humanity’s contribution to global warming, by using genomic approaches to reduce methane production by soil microbes,” he added.
“By partnering with CGIAR, the IGI can ensure that the products of its research will benefit farmers and consumers in some of the world’s poorest countries, where CGIAR has been working for 50 years and has extensive partner networks,” said Dr. Melinda Kliegman, Director of Public Impact at the IGI. “Together we can accelerate the development and delivery of more climate-resilient, productive and nutritious crops for resource-poor farmers and consumers.”
Over the next five years, the IGI and CGIAR will use the latest breakthroughs in genomic science to enhance the resilience and productivity of farmers in low- and middle-income countries and improve the wellbeing and livelihoods of women and men in some of the world’s poorest communities.

Introducing mechanization services in any smallholder farming community has proven to yield multiple benefits largely aimed at increasing farming efficiency but importantly creating a solid economic base to boost farmer incomes. Anchored on the two-wheel tractor along with implements for land preparation, planting, harvesting, shelling, transporting, appropriate-scale mechanization has in the last seven years gained currency across African farming households.
Interventions such as the mechanization pilot implemented by the International Maize and Wheat Improvement Center (CIMMYT) provide a channel through which smallholder farmers with access to some financial resources can invest to become a viable enterprise. The aim of this intervention is not to make every farmer own its own machinery, which would be costly and inefficient, but to train farmers to become service providers to other community members. This model has been effectively tried before in other places under the Farm Mechanization and Conservation Agriculture for Sustainable Intensification (FACASI) project.
A recent visit to two service providers in southern Zimbabwe, demonstrates the high returns on investment achieved through enrolling in mechanization service provision.
Two service providers, one vision: Profit
Julius Shava (53) and Prince Chimema (22), shared their experience in offering diverse transporting and land preparation services using the two-wheel tractor, trailer, direct seeder, and sheller procured through the initiative. Narrating how he learnt about the mechanization pilot and his subsequent enrolment, Shava explains how potential service providers had to make a financial commitment to the business before accessing the equipment.
“Through this mechanization business model, we would receive a two-wheel tractor, trailer, sheller, and seeder worth USD5,000, at a subsidized price of $USD2,500. The main condition for accessing this package was to pay a commitment fee of USD500 – there was no way I could let that opportunity slip away,” explains Shava.
“My wife and I decided to sell two cows to raise the funds and made the payment. Some community members were initially skeptical of the approach when it seemed that the consignment was delayed yet when the two-wheel tractor arrived, they were among the first to inquire about the services I was offering,” Shava adds.
“I made sure they all understood what I could provide for them using the 2WT and trailer such as land preparation and transportation – of manure, gravel stones and pit sand among other things.”

Shava and Chimema are among fifteen service providers leading in the mechanization pilot initiative launched in July 2020 in Masvingo district. The initiative is supported by the Swiss Agency for Development and Cooperation (SDC) and managed by the World Food Program (WFP). The private sector machinery company Kurima Machinery facilitates provision of the two-wheel tractor, planter, trailer and sheller while the Zimbabwe Agriculture Trust (ZADT) manages the lease-to-own business model anchoring the mechanization pilot to the financial sector.
Counting the cost and returns
“How much turnover does a service provider realise on average?” is a question frequently asked by other farmers keen to take up the enterprise.
Shava explains the factors he considers, “When someone is hiring my services, I charge according to the distance and load to be transported.” For example, for a 200m delivery radius, I can charge USD5. However, for land preparation and ploughing, I charge USD100 per hectare.” He quickly adds that he also factors in his labor, fuel requirements and time into the final price of his service – a principle he learnt during a specialized technical and business training provided by Gwebi College of Agriculture for the mechanization pilot.
In addition, using the two-wheel tractor is efficient as a hectare is completed in about one hour where an animal drawn plough takes up to six hours or more, depending on the soil type. The reduced drudgery allows farmers to rest their livestock and adopt more efficient and sustainable land preparation technologies. Shava notes that these advantages are immediately apparent to farmers who seek the service.
Customers often pay in cash which is convenient for him as he saves the money or uses some of it to meet expenses related to the service provision. “So far I have reached up to 7 customers after two months from the Nemamwa area in Ward 12 of Masvingo and they were seeking different services. “For land preparation they were paying USD100 per hectare. In Ward 8, I managed to get about three customers.
“When it comes to pricing, I leave room for negotiation because it is inevitable that customers will always ask for a discount, but I ensure that I do not incur losses.” Since venturing into mechanization service provision, Shava has realized a gross income of USD$600 before deducting expenses such as fuel and regular maintenance. However, the two-wheel tractor is fuel efficient – utilizing at least seven liters of diesel per hectare. Diesel fuel is purchased in Masvingo town or from informal markets at the business center at a cost of USD1 per liter.
Young service providers making their mark
Service providers such as Prince Chimema, who are young, energetic and business minded are also among those quickly realizing the high returns on the small mechanization investment. Coming from a family of seven, Chimema – recently married and with a two-year old child – has found a secure income stream in service provision of different mechanization services.
“I am grateful for the financial support from my parents that enabled me to enroll into the mechanization pilot program,” says Chimeme. Like Shava, Chimema’s parents sold two cows to raise the USD500 commitment fee. Soon, Chimema was approaching his relatives and neighbors in the community demonstrating the transporting, planting and land preparation services that he could provide. “Some of my customers would have seen me delivering manure or quarry stones to another household before requesting for my services; that is how my customer base has increased steadily.”
When pricing, Chimema considers the distance, fuel and time it will take to deliver the load. “In this area, requests are for transporting manure, quarry stones, pit sand and river sand. The price ranges from USD4 – USD8 per load. While most villagers pay in cash, a few may request to pay in kind using chickens,”
Chimema’s marketing strategy has been to push volumes by advertising his transporting services to other farmers outside of Ward 18. To date, he has focused on clients requiring transportation services. In Wards 18 and 19, Chimema has served a total of 60 customers, generating USD400 within the first two months of commencing the business.
Challenges and early lessons
Venturing into small mechanized service provision has not been without its challenges as attested by Chimema and Shava, “A lesson I learnt from the onset is never to overload the trailer beyond the recommended capacity,” explains Chimema. “During the mechanization training, we were advised that the trailer’s maximum carrying capacity is between 750-1000kg but at times I could overlook this leading to faults developing on my tractor,” says Prince.
Fuel access also presents challenges at times. “We have to get fuel from Masvingo because the quality of fuel here in the ward may be compromised while the price is slightly inflated because of the middlemen selling the fuel.
The delay in delivery of tractor-drawn direct seeders reduced the potential number of customers for both Chimema and Shava for planting services, as most farmers had proceeded to plant given the early onset of the rainy season. However, both service providers are hopeful that in the next season, with all the equipment in place, they can provide the full range of services to fellow smallholders.
Continuous improvement of the technology by including a toolbar is currently underway, which eases the level of effort required to operate the two-wheel tractor, making it more flexible for the service providers.

A vision for expansion and rural transformation
Chimema and Shava are optimistic about the future growth and performance of their business. Both aspire to expand their service provision over the coming five years by purchasing a second two-wheel tractor and creating employment for other villagers. “The income for the second two-wheel tractor should be generated from the current business” explains Shava.
In addition to the land preparation and transporting services, the maize sheller is set to increase their income. With a shelling capacity of 3-4 tons per day, the maize sheller significantly reduces the amount of time and effort required to shell a ton of maize manually (12.5 days).
“The priority now is to make sure that the loan repayment happens smoothly because I am generating enough income to pay back up for my package,” explains Shava. Once the payment is done, Shava would like to set up a borehole and drip irrigation system for their family plot and complete construction of his house in Masvingo town.
Chimema, on the other hand, is keen to start a poultry project. He is currently assisting his parents to pay school fees for his younger sibling but believes the poultry project will increase his income stream. “As I broadcast and market my services by word of mouth and through mobile platform messages; there is room for me to expand beyond Ward 18 and 19,” says Chimema. “I hope to employ at least two more people in the coming two or three years, to help me deliver the services to other farmers,” he adds.
“With the business experience gained from the current season, small mechanization service providers such as Chimema and Shava can increase the portfolio of services to customers”, says Christian Thierfelder, Principal Scientist at CIMMYT, leading the effort. “For example, at planting stage, service providers could provide a complete package for farmers including seed and fertilizer as well as a supply of appropriate herbicides for weed control as part of the land preparation and direct seeding service. Such an offering increases the value of the service and affords farmers the opportunity to witness the full benefits of small mechanized agriculture”, Thierfelder says.
“We have to provide farmers with options to abandon the hoe. The drudgery of farming has made this profession so unattractive that a rural exodus is looming. Providing business, employment and entrepreneurship will bring back hope and will lead to a true rural and agriculture transformation in Zimbabwe.” The high return on investment of the mechanized package makes it a viable year-round business option for farmers and entrepreneurs in rural Masvingo. The pilot is providing a proof of concept that this model works, even under low-potential environments.

The ever-changing environmental conditions and the urgency to improve food production and productivity for growing populations have ushered in the necessity for smallholder farmers to have widespread access to improved seed in the last mile. However, adequate access to the preferred, good-quality seeds that are climate-resilient and nutrition-dense is essential to farmers’ food and livelihood security. While seed security is an important first step to improved food production in developing countries and well examined in disaster situations, it remains understudied concerning long-term seed sector development, says a new study.
The Food and Agriculture Organization of the United Nations (FAO) describes seed security as “ready access by rural households, particularly farmers and farming communities, to adequate quantities of quality seeds adapted to their agro-ecological conditions and socioeconomic needs, at planting time, under normal and abnormal weather conditions.” In 2016, FAO specified two elements: varietal suitability (traits that respond to farmers’ preferences) and resilience (stability of seed system in the context of shocks) in addition to seed quantity, quality, and access identified in the earlier conceptualization of seed security.
Widespread seed insecurity
The study analyzed farmers’ seed use and preferences (demand-side) and the role of actors and institutions (supply-side) to understand farmers’ seed security. The latter was examined within the context of the recently adopted Pluralistic Seed System Development Strategy (PSSDS) of Ethiopia to understand how they affect the availability, quantity, quality, accessibility, and suitability of seeds from different sources. They focused on seed systems in two districts in Central Ethiopia — subsistence teff-growing and commercial wheat-growing districts. Since it started its operation in Ethiopia, CGIAR’s International Maize and Wheat Improvement Center (CIMMYT) has been one of the major actors in the commercial wheat district covered in this study. CIMMYT has contributed to the capacity building of Kulumsa Agricultural Research Center, a center of excellence for wheat research and development in East Africa that has released over 70 improved bread wheat and durum wheat varieties.
Despite great strides made in improving the seed sector in Ethiopia, the study found that the farmers in the two districts predominantly rely on the informal seed systems, concluding widespread seed insecurity in both regions. The study reported discrepancies between seeds farmers say they prefer and those they actually use. This discrepancy is due to the limited availability of improved varieties and specially certified seeds of these varieties, challenges with seed quality from some sources, and inequitable access to preferred seed and information according to sex, age, and wealth.
Explaining the finding concerning the widespread seed insecurity observed in the study districts, Teshome Hunduma, the lead author of the study, noted: “We were able to reveal some of the social, political, and institutional constraints and opportunities that underlie chronic seed insecurity among smallholder farmers in the two districts in Ethiopia. The country has a good seed sector development policy, for instance, the PSSDS, but these constraints limited its implementation.”
Women empowerment and access to certified seeds
In the study districts where CIMMYT operates, wealthy farmers aligned with the Ethiopian government received a privileged position as model farmers enjoyed increased seed access. Likewise, female-headed households targeted by the extension services had improved access to certified seeds. The presence of development actors, including CIMMYT alongside its partners such as Kulumsa Agricultural Research Center, actively contributed to the “unusual empowerment of women in the predominantly wheat-growing districts,” according to Hunduma. Hunduma referred to the following excerpt from the study to confirm his upbeat impression during his field research.
The study reports: “the women focus group participants highlighted unexpectedly positive empowerment of female heads of household and their related access to improved agricultural technologies [improved wheat]:
Unfortunately, all of us are on our own, i.e., we are widows and divorcees. ( . . . ) We do everything that most men do in farming. In the past, women, including widows and divorcees, were not considered equal to men. Now, we have more freedom and voice. We equally participate in meetings, trainings, and access inputs as men. We express our ideas in public gatherings… We learnt new techniques and gained skills in agriculture. We have better savings; some of us have saved between 70,000 to 100,000 ETB. We have full control over our incomes and resources. We hire labor and rent land to expand our production.
According to Hunduma, “development actors, including CGIAR and its partners, targeted female heads of households for varietal adaptation trial, seed multiplication, extension and credit services, which led to a significant push for a gender-sensitive approach to agricultural development.”
Over the past two decades, Ethiopia has also achieved high wheat production levels and productivity due to the germplasm that CGIAR introduced in the country in collaboration with its partners. This strategy has firmly put the country on the right path towards wheat self-sufficiency.
As national seed policies and programs in developing countries have primarily focused on the formal seed supply system, farmers’ use of seeds from the formal seed system remains limited. The pluralistic seed system approach could appear to provide a path to seed security in developing countries. Nevertheless, political, organizational, and economic interests within key institutions represent significant obstacles, which need to be addressed. The study concludes that efforts to support farmers’ access to seeds should recognize the complementarity of formal and informal seed systems. Thus the study advocates a pluralistic approach to seed sector development by promoting complementarity of activities between value-chain components of each seed system.
