Despite the development of improved wheat varieties with increased productivity, farming systems in the Global South are still marred by inequitable access based on gender and other social characteristics.
Focusing on Ethiopia and India due to their large wheat economies and challenges with inequality, researchers assessed the barriers preventing male and female smallholders from using modern wheat varieties. Issues covered through evaluation could include wheat varietal trait preferences, adoption of technology, and decision-making and labor-use changes associated with new varieties.
Concluding the paper is the argument that institutional arrangements in research and development (R&D) programs must transform to address gender equity and inclusivity in wheat improvement.

Climate change is predicted to cause losses of more than 20% in agricultural production by 2050. With a growing global population, crops adapted to the effects of climate change, such as drought and heat, are necessary for the maintenance of productivity levels to meet the demand for food.
Scientists from the International Maize and Wheat Improvement Center (CIMMYT), in collaboration with scientists from the Universidad Autónoma Agraria Antonio Narro, set out to analyze bread wheat landrace traits against seven climactic variables: mean temperature, maximum temperature, precipitation, precipitation seasonality, heat index of mean temperature, heat index of maximum temperature, and drought index. The method used genome-environment associations (GEA) and environmental genome-wide association scans (EnvGWAS), which have traditionally been poorly applied in this type of research.
Based on a sample of 990 bread wheat landraces from the CIMMYT genebank, the study discovered proteins associated with tolerance to drought and heat. With these results, new genotypes with resistant alleles can be selected for breeding programs to produce resistant varieties adapted to extreme environments and the effects of climate change.
This work was implemented by CIMMYT as part of the Seeds of Discovery (SeeD) Initiative in collaboration with Universidad Autónoma Agraria Antonio Narro (UAAAN), made possible by the generous support of the MasAgro project funded by the Government of Mexico’s Secretariat of Agriculture and Rural Development (SADER).

CGIAR research centers involved in the One CGIAR Plant Health Initiative joined forces at the International Plant Health Conference in London on September 21-23, 2022 to highlight the importance of global partnerships in effectively preventing and managing devastating pest and disease outbreaks in the Global South.
In an interactive side event on Plant Health Management in the Global South through Partnerships on September 21, the Plant Health Initiative team presented on and discussed: global diagnostic and surveillance systems against plant pests and diseases; risk assessment and preparedness for proactive response; integrated pest and disease management; mycotoxin mitigation strategy; and gender and social inclusion.
The CGIAR Plant Health Initiative, launched in January 2022, aims to protect agriculture-based economies of low and middle-income countries in Africa, Asia and Latin America from pest and disease outbreaks in major crops by leveraging and building viable networks across an array of national, regional, and international institutions.
Building on a track record of more than 50 years of impactful research, the Plant Health Initiative aims to develop and deploy solutions through partnerships, and to achieve impacts that contribute towards several Sustainable Development Goals (SDGs).
Healthy crops for a healthy planet
Showing the strength of partnerships in action, researchers from the International Maize and Wheat Improvement Center (CIMMYT), Alliance Bioversity-CIAT (ABC), the International Institute of Tropical Agriculture (IITA), the International Potato Center (CIP), and the International Food Policy Research Institute (IFPRI) highlighted the Initiative’s activities and sought feedback from the plant health experts participating in the session.
Martin Kropff, CGIAR Science Director of Resilient Agrifood Systems, welcomed the participants to the session. Prasanna Boddupalli, CGIAR Plant Health Initiative Lead & Director of CIMMYT’s Global Maize Program, introduced the Initiative and its scope, emphasizing the inclusive partnerships. This was followed by presentations from Monica Carvajal (ABC), Lava Kumar (IITA), Alejandro Ortega-Beltran (IITA), Nozomi Kawarazuka (CIP), and Yanyan Liu (IFPRI).
Time was dedicated to engaging participants through Mentimeter polling on specific questions related to plant health management. Participants also shared their views on plant health research coordination, capacity strengthening, and knowledge exchange between the Global North and Global South, with a focus on improving food security and livelihoods of smallholders.
The event was successful not only in generating greater understanding of the Initiative amongst the participants, but also in developing significant interest from the participants to contribute to the Initiative’s goals with collective actions, all for the benefit of smallholders in the low- and middle-income countries of Africa, Asia, and Latin America.
Establishing wider networks for plant health
The Plant Health Initiative team, together with Kropff, also had a productive discussion on September 22 with Osama El-Lissy, International Plant Protection Convention (IPPC) Secretary, on opportunities for joint actions on plant health management in the Global South by IPPC and the CGIAR Plant Health Initiative, together with national partners.
Boddupalli also participated in a workshop on September 20 organized by Euphresco, a network of organizations that fund research projects and coordinate national research in the phytosanitary area, at the Department of Environment, Food & Rural Affairs (DEFRA) in the United Kingdom, on shaping global plant health research coordination. The workshop participants discussed and endorsed several actions for advancing global plant health research coordination.

Using data from 2,279 farm households in Ethiopia, the results show a significant gap due to the observable and unobservable different characteristics of households headed by men and women. For example, women are less likely to adopt climate change adaptation measures due to their workload in household chores. However, evidence suggests that when the gender gap shrinks, climate change adaptation can be improved in female-headed households by almost 19%.
The study determined that policies must tackle unobservable characteristics in order to address the gender gap. Short-term projects and long-term gender-informed policies are essential in creating equitable opportunities for all.
This crucial work will support developing countries to achieve targets set by the United Nations Sustainable Development Goals (SDGs) and farming households’ susceptibility to the risks of climate change.

Wheat constitutes as much as 60% of daily calorie intake in developing countries. However, rising temperatures caused by climate change is reducing farmers’ yields.
Matthew Reynolds, Wheat Physiologist, and Maria Itria Ibba, Cereal Chemist, share how their work contributes towards securing food security and nutrition by breeding new wheat varieties.
Ten years ago, a foundation was laid on the principles of Norman Borlaug to translate agrarian challenges into opportunities through collaboration between the International Maize and Wheat Improvement Centre (CIMMYT) and the Indian Council of Agricultural Research (ICAR). This major step toward sustainable food and nutrition security was taken through the establishment of the Borlaug Institute for South Asia (BISA) as an independent, non-profit research organization.
Today, BISA is a global name in agriculture research with a vision to promote food security, nutrition, stable livelihoods, and eco-friendly practices in South Asia. Given the prominent challenges of climate change in these economically fragile agroecosystems, the partnership between BISA, ICAR, and CIMMYT plays a pivotal role in developing improved wheat and maize varieties with climate-smart and conservation agriculture-based practices.
A decade of impact
One of the most significant outcomes of BISA’s work has been its contribution to building a vast, solid network for evaluating and disseminating new high-yielding and climate-resilient wheat varieties for India and other South Asian countries in close partnership with ICAR and CIMMYT. BISA’s transformative solutions and science-led research are critical to targeting stressed resources and attaining global food security.
With support from ICAR and CIMMYT, BISA has developed state-of-the-art research facilities at its three strategically selected research stations, having 1,200 acres of land that the Government of India, jointly with the respective state governments, generously granted to the project. Located in three disparate agro-climatic and socioeconomic environments, these sites are model research farms supporting agriculture research in South Asia. The learning labs at BISA emphasize that scaling climate-smart villages also strengthen climate-resilient agriculture, primarily through addressing challenges such as residue burning. BISA’s collaborative and inclusive approach is more relevant today when the world is grappling with various food and nutrition insecurity challenges.
Time for expansion
BISA envisages attracting countries from south Asia, the Bay of Bengal Initiative for Multi-Sectoral Technical and Economic Cooperation (BIMSTEC) and the South Asian Association for Regional Cooperation (SAARC), as well as National Agricultural Research Systems (NARS), national research institutes, private sector companies, and civil society organizations as active partners for expanding reach in the region. To this end, BISA has completed extensive work in Nepal and Bangladesh and has extended its services to Bhutan and Sri Lanka.
Still, more needs to be done in South Asian countries. Therefore, there is an urgent need for a strong commitment to harnessing the best of international scientific discoveries with local efforts. Collective action is to be garnered to provide trusted and effective mechanisms for developing and sharing cutting-edge agricultural technologies in the South Asian region.

To this end, a BISA High-Level Meeting was organized on September 1 and 2 in Delhi, with senior government representatives from the NARS in Bhutan, Sri Lanka, Pakistan, Nepal, Bangladesh, and India. The meeting provided a forum to identify opportunities to co-create and deploy innovative, multidisciplinary solutions to effectively address the transboundary challenges related to food, nutrition, and environmental security faced by farming communities in South Asia. This platform strives to unite the scientific community and thought leaders to support research and development across the agriculture domain.
Delegates from these countries felt that there is a need for a robust program of germplasm exchange within the region, which is essential to strengthening agriculture’s resilience. All countries expressed a significant need to raise their capacity of young researchers in advanced research techniques related to genomics, phenotyping, climate-smart agriculture, precision agriculture, and digital technologies. Delegates also discussed BISA’s role as a research and innovation regional catalyst, innovation hub, and integrated research platform to build resilient agrifood systems and achieve long-term sustainability and resilience for food security in South Asia.
BISA’s farm-ready research, from setting up climate-resilient villages and developing viable alternatives to rice residue burning to facilitating an open exchange of elite germplasm and cutting-edge technologies, reflects not only the vision of CIMMYT but also the philosophy of our mutual inspiration, Borlaug, who believed strongly in sharing knowledge and “taking it to the farmer”.

As a partner to the GAP Initiative, CIMMYT’s submission to the report is part of the Stories of partnership and productivity growth section. It explores the interdependency and vulnerability of food systems to market shocks and the long-term impacts of these shocks on vulnerable communities, particularly in the Global South.
To build agricultural resilience that can overcome threats of food insecurity and malnutrition, CIMMYT recommends targeted expansion of agricultural production and high levels of investment in research and capacity development.
Tek Sapkota, Agricultural Scientist and System/Climate Change Specialist with CIMMYT’s Sustainable Agrifood Systems (SAS) program, was a speaker at the launch event, which explored the outlook for agricultural productivity growth in the face of conflicts, COVID-19 and climate change. Presenters also examined where agricultural productivity is stagnating or falling and its repercussions for food security and the environment, and how to accelerate sustainable productivity growth at all scales of production.

The Accelerating Genetic Gains in Maize and Wheat (AGG) Project, which is halfway through its implementation, continues to register impressive achievements. At a meeting focusing on the project’s Maize component, held in Nairobi during July 25-28, B.M. Prasanna, Director of the Global Maize Program at the International Maize and Wheat Improvement Center (CIMMYT), highlighted the project’s major achievements in the opening session.
“One of the most important achievements of this project is increasing use of powerful tools and technologies to increase genetic gains in maize breeding pipelines in Africa,” said Prasanna. He noted that the AGG partners are showing keen interest in doubled haploid-based maize breeding. Prasanna pointed out that currently work is ongoing to produce third-generation tropicalized haploid inducers which, in combination with molecular markers, will support accelerated development of improved maize germplasm, a key objective of the AGG Project.
Prasanna also pointed out a significant increase in adoption of stress-tolerant maize in Africa – from less than half a million hectares cultivated under stress tolerant maize varieties in 2010, to 7.2 million hectares currently in 13 African countries, benefitting 44.5 million people. He explained that drought-tolerant maize is not only a productivity enhancing tool but also an innovation for improving the welfare of farmers. “It reduces the probability of crop failure by 30 percent and provides an extra income to farmers at a rate of approximately $240 USD per hectare, equivalent to about nine months of food for a family at no additional cost,” he said, adding that the essence of research is taking improved genetics to farmers and impacting their lives.
He noted there is remarkable progress in maize varietal turnover in sub-Saharan Africa, pointing out particularly efforts in Ethiopia, Uganda, Zambia and Zimbabwe, where old maize varieties, some dating as far back as 1988, have been replaced with newer climate-resilient varieties. Prasanna highlighted the need to engage with policy makers to put in place appropriate legislation that can accelerate replacement of old or obsolete varieties with improved genetics.
Prasanna stressed on the importance of rapid response to transboundary diseases and insect-pests. CIMMYT has established fall armyworm (FAW) screening facility at Kiboko, Kenya, and that more than 10,000 maize germplasm entries have been screened over the last three years. He applauded South Sudan for being the first country in sub-Saharan Africa to recently release three CIMMYT-developed FAW-tolerant hybrids. He said CIMMYT’s FAW-tolerant inbred lines have been shared with 92 institutions, both public and private, in 34 countries globally since 2018.
Kevin Pixley, CIMMYT Global Genetic Resources Director and Deputy Director General, Breeding and Genetics, encouraged the participants to continuously reflect on making innovative contributions through the AGG project, to serve smallholder farmers and other stakeholders, and to offer sustainable solutions to the food crisis that plagues the world.

Synergies across crops and teams
Pixley pointed out that though the meeting’s focus was on maize, the AGG Project has both maize and wheat components, and the potential for learning between the maize and wheat teams would benefit many, especially with the innovative strides in research from both teams.
Pixley referenced a recent meeting in Ethiopia with colleagues from the International Institute of Tropical Agriculture (IITA), the International Center for Tropical Agriculture (CIAT) and CIMMYT, where discussions explored collaboration among CGIAR centers and other stakeholders in strengthening work on cowpea, chickpea, beans, sorghum, millet and groundnut crops. He noted that maize, wheat and the aforementioned crops are all critical in achieving the mission of CGIAR.
“CIMMYT has been requested, since August of last year, by CGIAR to initiate research projects on sorghum, millet and groundnut because these crops are critical to the success of achieving the mission of CGIAR,” said Pixley. “So, we have recently initiated work on the Accelerated Varietal Improvement and Seed Systems in Africa (AVISA) project together with partners. This is the first step towards OneCGIAR. It’s about synergies across crops and teams.”
Collaborative research commended
The meeting’s Chief Guest, Felister Makini, Deputy Director General – Crops of the Kenya Agricultural and Livestock Research Organisation (KALRO), commended the collaborative research undertaken by CIMMYT and other CGIAR partners. She noted that the partnerships continue to build on synergies that strengthen institutional financial, physical and human resources. She attested that collaboration between KALRO and CGIAR dates back to the 1980s, beginning with training in maize breeding, and then subsequent collaboration on developing climate-adaptive improved maize varieties and training of KALRO technicians in maize lethal necrosis (MLN) screening and management among other areas.
Maize and wheat are staple food sources in Kenya and sub-Saharan Africa and as the population increases, new methods and approaches must be found to accelerate development and deployment of improved maize and wheat varieties. She challenged the partners to intensify research and come out with high-yielding varieties that are resistant or tolerant to a wide range of biotic and abiotic stresses.
The Inaugural Session also featured remarks from the representatives of the AGG funders – Gary Atlin from the Bill & Melinda Gates Foundation, Jonna Davis from the Foundation for Food and Agriculture Research (FFAR), and John Derera from IITA, an AGG project partner.
A total of 116 participants, including representatives from National Agricultural Research Systems (NARS) in 13 AGG-Maize partner countries in Africa and seed companies, participated in the meeting. Participants also visited the KALRO-CIMMYT MLN Screening Facility at Naivasha, and KALRO-CIMMYT maize experiments at Kiboko, Kenya, including the work being done at the maize doubled haploid and FAW facilities.
Ouattara Ali grows rice and maize on a small parcel of land in a village on the outskirts of Bobo Dioulasso, Burkina Faso’s second-largest city.
In the eight years since he began farming, he has faced significant challenges because he depends on traditional practices. Other smallholders in the community are in a similar situation, which limits their ability to realize greater prosperity.
A steady trickle of young adults is leaving the area to find work in the city as an alternative to the difficulty of trying to make ends meet on limited hectarage, coping with erratic harvests and with no guarantee of long-term financial stability.
This story is not unique to Ali and his community – it is familiar across Burkina Faso and other nations where the problems of food security, reliable employment, and dependable income limit economic development in rural areas.
Mechanization as a business
To help communities tackle these challenges, in 2014 Germany’s Federal Ministry for Economic Cooperation and Development (BMZ) created the special initiative One World No Hunger, which launched Green Innovation Centers for the Agriculture and Food Sector (GIC) in 14 countries in Africa and two in Asia. In Burkina Faso, the GIC focuses primarily on the sesame and rice value chains in the Hauts-Bassins, Cascades, Boucle du Mouhoun, and Sud-Ouest regions.
These initiatives include the introduction of mechanized agricultural practices that can increase yields of maize, rice, and other crops. In connection with GIC, farmers like Ali have used machines across the full agricultural value chain – from seed development to post-harvest – to improve their own crop yields. Mechanization has also enabled them to offer their services for hire to other farmers in the area.
Mechanization is a significant economic driver for boosting development of farm areas, but to achieve sustainable success and maximize the ability to bring transformative change to communities, business model development must be a critical focus area.

In August, the International Maize and Wheat Improvement Center (CIMMYT) and Deutsche Gesellschaft fuer Internationale Zusammenarbeit (GIZ) GmbH, collaborated with the United Nations Food and Agriculture Organization (FAO) and Germany’s University of Hohenheim to host a webinar on business models for agricultural mechanization projects. Joining the conversation were 48 participants from countries including Burkina Faso, Nigeria, Benin, and Vietnam.
During the webinar, FAO Senior Consultant Karim Houmy presented research on business models from two case studies of agricultural mechanization hire services in sub-Saharan Africa. Houmy found five basic types of business model, each with its own structure, complexity, and requirements, but he also outlined common features that characterize all successful models.
Many models, a few key principles
The basic business model for agricultural mechanization involves a farmer who uses machinery on their own crops, and then subsequently provides the same services to neighboring farmers. This model is probably the simplest and least expensive. Any smallholder who can procure the necessary machinery, parts, and training can launch this small business, generate additional income, and help neighbors increase their yield. This model also has limits, however, as it restricts farmers to a relatively small footprint of clients whose farms are located near the service provider.
At the other end of the scale is an enterprise model where an entrepreneur does not own any farm machinery but uses mobile phones and geographic information system (GIS) technology to connect farmers with service providers. This model provides a much greater geographical scope as well as greater opportunities for growth and innovation. It also adds layers of complexity that require a network of intermediaries – from machinery dealers and mechanics to booking agents – and bank financing.
The more diverse in operational offerings a business model is, the more promise it holds for generating economic growth and food security. This occurs by spreading activity across a wider geographic region, providing yield-increasing services for more farmers, employing more workers, and generating increased demand up and down the supply chain.
In addition to laying out the range of business models in operation today, Houmy identified success factors important for all, including long-term access to financing and local infrastructure, both of which are structural issues that entrepreneurs have less immediate control over. GIC works to address this shortcoming by involving a broad range of stakeholders, including government actors, in addressing issues of sustainability.
Houmy encouraged entrepreneurs to focus on areas like cultivating a skilled staff, building close links with processors and aggregators, and diversifying the services they offer. This sort of business model training can translate into significant improvements on the ground.
Building a business
Life began to change dramatically for Ali when his local agricultural bureau connected him to the GIC in his area.
Through his relationship with GIC, Ali gained access to some basic mechanized farming equipment, including disc plows, harrows, and planters, which revolutionized his work. He now prepares his rice and maize fields more quickly and evenly. He plants them more efficiently and spends less time harvesting while producing equal and sometimes higher yields. To support this transition, GIC provided training in agricultural mechanization, seed production, and financial management.
Initially, Ali sustained an injury while using a harrow and trailer. Thankfully, this did not slow him down for long, he said. He learned how to regularly tighten components of the machine to avoid further injuries and other safety problems.
Soon, Ali began using his machines to provide services to his neighboring farmers as well, helping them with land preparation, transportation, and planting.
Today, 22 local farmers use Ali’s services, and his community is experiencing the benefits. Less time is spent on planting and harvesting while agricultural yields are increasing. Mechanization marked a sharp decline in the drudgery associated with farming tasks, especially for the area’s youth and women.
Ali is thinking about the future by expanding and diversifying. He plans to buy a seeder and a thresher if he can get financing, and he is interested in additional training. He is developing a business plan for a larger enterprise that would be “the farmers’ one-stop shop” for mechanization services in his area. With the profits so far, he has built a house for his wife and two children and bought a small car.
GIC has supported 26 service providers like Ali in Burkina Faso as well as others in Benin, Mali, and Kenya. Over time, the proliferation of sustainable agricultural operations like Ali’s, as well as their growth into more complex and more profitable business networks, holds enormous promise for rural areas where food security, sustainable employment and a baseline of prosperity have been elusive for far too long.

A systematic review conducted by a team of scientists from the International Maize and Wheat Improvement Center (CIMMYT) has revealed that many farmers around the world incorrectly identify their crop varieties, with significant impacts on their farming practices, yields, profits, and research.
The review, published this month in Outlook on Agriculture, brings together information from 23 published studies to sketch crop variety misclassification among farmers, its determinants, and the implications of classification errors on the farm and in research.
“We found that seven out of ten farmers incorrectly identified the grown variety when they were asked to identify the variety by its specific name. When farmers were asked if the grown variety was either improved or local, three out of ten farmers made incorrect classifications,” said Michael Euler, first author of the study and agricultural resource economist at CIMMYT.
Whether farmers correctly identify crop varieties has a knock-on effect on their farming practices, which in turn affects their crop yields and income. This can bleed into research, impacting experiments and evaluation studies of agricultural technologies and methods. For example, scientists might assign treatment and control groups based on incorrect farmer variety classification, potentially leading to biased estimates and data discrepancies.
“Varietal misidentification can lead to improper agronomic management, forgone farm revenue, and seed system malfunctioning. From a monitoring and evaluation perspective, the potential presence of bias in estimates due to varietal misclassification is problematic as it may mask the true costs and benefits of seed technologies,” said Euler.

The study is the first systematic review of the use of DNA fingerprinting – a method that uses molecular markers to identify crop varieties – to assess how accurate farmers are in identifying their varieties and the impacts this has on seed markets, crop performance, farm profits, and research.
“The use of DNA fingerprinting to identify crop varieties in farmers’ fields has emerged only recently. The review of existing literature, nonetheless, shows its potential to strengthen the functioning and effectiveness of seed markets, supply chains, and extension services,” said Vijesh Krishna, co-author of the study and senior scientist at CIMMYT.
The results of the review show that cases of farmers misidentifying varieties are widespread, causing problems for farm productivity and profits, as well as research. The authors also found that DNA fingerprinting can shed light on what drives farmers to misidentify varieties and how they can minimize misclassification.
“Varietal misidentification is not only related to farmer and farm characteristics but also depends on the properties of the seed system through which seeds are obtained. We need more comprehensive modeling approaches to improve our understanding of the system-level drivers of farmer varietal misclassification,” said co-author and CIMMYT senior agricultural economist Moti Jaleta.
However, like most technologies, DNA fingerprinting has its limitations. It may not always be feasible in all settings, and the costs may offset the benefits in areas where formal seed markets are already well-functioning.
“DNA fingerprinting is considered a reliable method to accurately identify varieties grown by farmers and is increasingly seen as the ‘gold standard’ for varietal identification. However, it requires a high-quality reference library, a well-designed sampling strategy, and accurate tracking of plant samples from collection sites to the point of analysis,” said CIMMYT senior scientist and co-author David Hodson.
Based on the results of the analysis, the authors recommend integrating DNA fingerprinting into existing national data collection toolboxes to accurately estimate adoption and turnover rates of improved crop varieties and to evaluate existing genetic crop diversity on farms. Understanding and promoting genetic crop diversity are crucial steps for enhancing food security and increasing the climate and pest and disease resilience of crops.
Having accurate estimates of adoption and turnover rates of varieties, combined with seed supply system assessment, can also help researchers and decision-makers pinpoint any bottlenecks or loopholes in the “lab to farm” process, according to the authors.
“The review aims at helping researchers and policymakers strategize to more effectively assess the functioning and effectiveness of seed diffusion systems to deliver modern seeds to smallholders,” concluded Krishna.
Wheat is a strategically important crop for Afghanistan because as a major source of nutrition — accounting for up to 60% of a family’s daily caloric intake — it is linked directly to national food security. However, despite occupying over 2.5 million hectares of arable land across the country, Afghanistan does not currently produce enough wheat to meet the needs of a growing population. On average, annual production is estimated at around 5 million metric tons — 2 million metric tons less than needed — and as a result Afghanistan makes up this significant shortfall by importing wheat flour from neighboring countries where wheat productivity is significantly higher.
There is tremendous potential to increase national wheat productivity by introducing improved agronomic practices and making use of suitable farming technologies. However, given Afghanistan’s vast agro-ecological diversity, it is essential that best practices are recommended based on local conditions, as these vary greatly across the country.
Take seeding, for instance. Sowing wheat seed at the optimum time has been shown to help maximize yields and significant research has been undertaken to determine the optimal sowing dates for winter and spring wheat in different areas. These times are governed not only by environmental requirements and growing cycles, but also by the need to avoid certain diseases and insect pests, which may be more prevalent at specific times of year.
But these can vary widely even within a season. For example, research shows that the best time to sow irrigated winter wheat in Afghanistan’s hot and arid western provinces is from the second week of October up until the end of the month. However, the optimum window falls one month later in the more mountainous and forested provinces of the East, and even later for rain-fed wheat.
The same distinctions apply to seeding and fertilizer application rates, which can vary subtly between similar regions. Consider that the optimum seed rate for irrigated wheat sown using the broadcast method is the same in both the Northern and Central zones, 25-30 kilograms per jerib (approx. half an acre). One might expect the optimum rates for row cultivation to match, but in fact they differ by two kilograms. This might not seem like much, but given how significantly seed density and spacing influence crop yield and quality, these figures are vital knowledge for farmers looking to maximize their yield potential.
To help disseminate these research-based recommendations to farmers and local agricultural extension staff, researchers at the International Maize and Wheat Improvement Center (CIMMYT) have partnered with Afghanistan’s Ministry of Agriculture, Irrigation and Livestock, Michigan State University’s Global Center for Food Systems Innovation and the USAID to compile four new booklets featuring zone-specific advice for irrigated and rain-fed systems in each of Afghanistan’s main agro-ecological zones.
Covering between four and ten provinces each, these guides include localized recommendations for the best sowing dates, nutrient management, weed management, and best practices in irrigation, arming wheat farmers with the key information they need to effectively increase production in their area and support the country’s wider food security needs.
More information is available in the booklets below:

Maize, along with wheat and rice, provides around 30% of food calories to more than 4.5 billion people in 94 developing countries. These statistics declare that maize is an important crop to ensure food and nutritional security for poor communities in Africa, Asia and Latin America.
Limited diversification in dietary food and higher per capita maize consumption indicates that a great proportion of the population in developing countries are lacking in essential nutrients like micronutrients and amino acids.
Rigorous efforts by International Maize and Wheat Improvement Center (CIMMYT) maize breeder Surinder K. Vasal and cereal chemist Evangelina Villegas in the early 1980s led to the development of an improved maize kernel with higher yield and vitreous appearance by combining the opaque-2 and genetic modifier systems by using backcrossing and recurrent selection. These efforts led to development of an improved maize known as quality protein maize (QPM).
QPM ensures the nutritional security of maize dependent communities. It is described as nutritionally superior maize with high lysine, tryptophan and leucine contents along with high biological value and high protein intake. QPM also has higher contents of non-zein protein (albumin, globulin and glutelin fractions), which are rich in lysine and tryptophan.
The development of QPM was comprised of a series of efforts across many decades to develop promising varieties. CIMMYT described the term QPM for maize genotypes with improved lysine and tryptophan contents and hard endosperm texture. Now, QPM is referred to maize genotypes with homozygous o2 alleles, increased lysine and tryptophan contents, and without harboring the negative pleiotropic effects of soft endosperm.
In recent years, CIMMYT has developed several QPM varieties across many countries with different genetic backgrounds. However, to fast track the deployment of QPM at scale, it needs a vibrant seed system in place and a viable business model which ensures an active engagement of seed producers, farmers and consumers.
This review article discusses the importance and timeline of various events in QPM development and dissemination, genetic basis and systems, breeding strategies, challenges and potential opportunities for QPM adoption. “We can consider the article as a compendium of QPM where it addresses historical background and scientific breakthroughs which will be useful to researchers, students and others who are looking for a comprehensive information on QPM,” said AbduRahman Beshir, CIMMYT’s senior scientist and maize seed systems specialist for Asia, who co-authored the publication.
A new special issue on gender research in agriculture highlights nine influential papers published in the past three years on gender research on crop systems including maize.
The virtual special issue, published earlier this month in Outlook on Agriculture, features work by International Maize and Wheat Improvement Center (CIMMYT) scientists on gender inclusivity in maize systems in Africa and South Asia.
In the Global South, women contribute substantial labor to agriculture but continue to face barriers in accessing agricultural resources, tools and technologies and making decisions on farms.
Combatting gender inequality is crucial for increasing agricultural productivity and reducing global hunger and poverty and should be a goal in and of itself. Evidence suggests that if women in the Global South had access to the same productive resources as men, farm yields could rise by up to 30 percent, increasing total agricultural output by up to 4 percent and decreasing the number of hungry people around the world by up to 17 percent.
The latest virtual special issue includes a review of existing research by CIMMYT gender experts, exploring issues and options in supporting gender inclusivity through maize breeding and the current evidence of differences in male and female farmers’ preferences for maize traits and varieties. The team also identified key research priorities to encourage more gender-intentional maize breeding, including innovative methods to assess farmer preferences and increased focus in intrahousehold decision-making dynamics.
The issue also features a study by CIMMYT and Rothamsted Research researchers on differences in preferred maize traits and farming practices among female and male farmers in southern Africa. The team found that female plot managers and household heads were more likely to use different maize varieties and several different farming practices to male plot managers and household heads. Incorporating farming practices used by female farmers into selection by maize breeding teams would provide an immediate entry point for gender-intentionality.
Also included is a recent paper by CIMMYT gender researchers which outlines the evidence base for wheat trait preferences and uptake of new farming technologies among male and female smallholder farmers in Ethiopia and India. The team highlight the need for wheat improvement programs in Ethiopia and India to include more gender-sensitive technology development, evaluation and dissemination, covering gender differences in wheat trait preferences, technology adoption and associated decision-making and land-use changes, as well as economic and nutritional benefits.
In a study carried out in the Eastern Gangetic Plains of South Asia, CIMMYT scientists investigated how changes in weed management practices to zero tillage – a method which minimizes soil disturbance – affect gender roles. The team found that switching to zero tillage did not increase the burden of roles and responsibilities to women and saved households valuable time on the farm. The scientists also found that both women and men’s knowledge of weed management practices were balanced, showing that zero tillage has potential as a gender inclusive farming practice for agricultural development.
Also featured in the special issue is a study by CIMMYT experts investigating gender relations across the maize value chain in rural Mozambique. The team found that men were mostly responsible for marketing maize and making decisions at both the farm level and higher levels of the value chain. The researchers also found that cultural restrictions and gender differences in accessing transport excluded women from participating in markets.
Finally, the collection features a study authored by researchers from Tribhuvan University, Nepal and CIMMYT exploring the interaction between labour outmigration, changing gender roles and their effects on maize systems in rural Nepal. The scientists found that the remittance incomes sent home by migrants and raising farm animals increased maize yields. They further found that when women spent more time doing household chores, rearing farm animals and engaging in community activities, maize yields suffered, although any losses were offset by remittance incomes.

Research shows that digital innovations can increase small-scale farmers’ incomes, boost the adoption of better practices, and increase resilience to climate shocks while reducing the gender gap and managing food system risks. However, these benefits are not universal. More than 600 million people and 40 percent of small farms are still not covered by mobile internet, especially in those countries most dependent on agricultural production. Across low- and middle-income countries, women are 7 percent less likely than men to own a mobile phone and 15 percent less likely to use mobile internet.
A new CGIAR Research Initiative, Digital Innovation, has been launched to research pathways to bridge this digital divide, improve the quality of information systems, and strengthen local capacities to realize the potential of digital technologies.

Based on a pilot study regarding the feasibility and cost effectiveness of several groundwater monitoring approaches for agriculture in Nepal’s Terai region, a water and food security specialist who led the research has recommended the use of phone-based systems.
Speaking to diverse experts at the recent World Water Week 2022 in Stockholm, Sweden, Anton Urfels, a systems agronomist at the International Maize and Wheat Improvement Center (CIMMYT), said that manual monitoring with phone-based data uploading is relatively low-cost and effective and could be scaled up across the Terai.
“One alternate monitoring approach studied — online data uploading — has substantially lower staff time requirements and technology costs and higher temporal resolution than phone-based monitoring, but does not provide real-time data and entails high technical skills, capital costs, and risks of theft and damage,” said Urfels in his presentation, ‘Upgrading Groundwater Monitoring Networks in Low-Income Countries’.
Urfels and partners also developed a prototype of an open-source groundwater monitoring dashboard to engage stakeholders, help translate raw data into actionable information, and detect water depletion trends.
Water has become a key part of food research and innovation, critical for sustainable and ecological intensification in agriculture, according to the scientist.
“Collecting groundwater data is difficult and the technology for monitoring is unreliable, which impairs effective modeling, decision-making, and learning,” Urfels explained. “Like other countries in the region, Nepal is increasing its agricultural groundwater consumption, particularly through private investment in irrigation wells and pumps that open irrigation to more farmers. This and climate change have altered groundwater recharge rates and availability, but national data on these trends are incomplete.”
An extensive lowland region bordering India and comprising one-fifth of the nation’s territory, the Terai is Nepal’s breadbasket.
Held yearly since 1991, World Water Week attracts a diverse mix of participants from many professions to develop solutions for water-related challenges including poverty, the climate crisis, and biodiversity loss. The 2022 theme was “Seeing the Unseen: The Value of Water”.
“I’d recommend more pilot studies on phone-based groundwater monitoring for other areas of Nepal, such as the Mid-hill districts,” Urfels said. “We also need to fine-tune and expand the system dashboard and build cross-sectoral coordination to recognize and take into account groundwater’s actual economic value.”
Urfels said the Nepal Ministry of Energy, Water Resources and Irrigation has requested the nationwide scale-out of a digital monitoring system, and CIMMYT and Nepal experts will support this, as well as improving the system, which would be freely available for use and development by researchers and agencies outside of Nepal.
