How can we ensure we have enough food to meet the demand by 2030? First, we need to understand food consumption patterns and how they are influenced by variables such as urbanization, population and economic growth, income, beliefs and more.
Agricultural economist Khondoker Mottaleb is working on a project to examine food demand by 2030, considering these factors. Watch him share preliminary results — in just one minute.
Maize is more than a crop in Mexico. In many cases, it connects families with their past. Landraces are maize varieties that have been cultivated and subjected to selection by farmers for generations, retaining a distinct identity and lacking formal crop improvement. They provide the basis of Mexico’s maize diversity.
Back in 1966-67, researcher Ángel Kato from the International Maize and Wheat Improvement Center (CIMMYT) collected 93 maize landraces samples from 66 families in Mexico’s state of Morelos. These seeds were safeguarded in CIMMYT’s Germplasm Bank, which today stores 28,000 samples of maize and its wild relatives from 88 countries.
50 years later, doctoral candidate Denisse McLean-Rodriguez, from the Sant’Anna School of Advanced Studies in Italy, and researchers from CIMMYT started a new study to trace the conservation and abandonment of maize landraces over the years.
The study shows that landrace abandonment is common when farming passes from one generation to the next. Older farmers were attached to their landraces and continued cultivating them, even in the face of pressing reasons to change or replace them. When the younger generations take over farm management, these landraces are often abandoned. Nonetheless, young farmers still value the cultural importance of landraces.
Maize landraces can be conserved “in situ” in farmers’ fields and “ex situ” in a protected space such as a germplasm bank or community seed bank. The loss of landraces in farmers’ fields over 50 years emphasizes the importance of ex situ conservation. Traits found in landraces can be incorporated into new varieties to address some of the world’s most pressing agriculture challenges like changing climates, emerging pests and disease, and malnutrition.
This research was supported by the CGIAR Research Program on Maize (MAIZE), the Sant’Anna School of Advanced Studies, Wageningen University and the Global Crop Diversity Trust.
Plant breeding, genetics, math and software development are all stereotypically male fields. For too long, women have been excluded from these fields for social, religious, cultural and “Oh, it’s a boys’ club, I don’t feel welcome” reasons, thus depriving scientific progress of great female minds and ideas.
In light of the International Day of Women and Girls in Science, we stopped to ask four scientists and leaders at the International Maize and Wheat Improvement Center (CIMMYT) why they chose science. Here are some inspiring highlights.
What made you want to become a scientist?
Margaret Bath, Member of the CIMMYT Board of Trustees: “I love food and I love science and math, so I had the opportunity to combine […] three things that I love very much and make a great career out of it. I’m a firm believer in math and science as an enabler for solving complex problems that face our society today.”

Cynthia Ortiz, researcher in CIMMYT’s Genetic Resources Program: “I remember one time when I was watching fireflies. My grandfather approached me and asked me if I understood why they shine and I said ‘no.’ I remember well what he said to me: ‘The world is much more than what we see, hear and feel.’ In that moment, I knew that I wanted to understand more about the things that surround us.”

What’s the best thing about being a scientist?
Aparna Das, Technical Program Manager in the Global Maize Program, CIMMYT: “The whole idea where I use information, knowledge and technology to generate biological products was very exciting for me. The biggest learning I have had in the 25 years of my career as a plant-breeding scientist […] has been how I can use the vast information, combine it with the present day technological advances and deliver something for the future, which can address the global food crisis problem, which is looming […] in the near future.”

Philomin Juliana, wheat scientist in CIMMYT’s Global Wheat Program: “How you can use scientific research to answer lots of different questions and how you can solve […] different problems using math, data analysis. All these are key questions that affect humankind today and how we can design future systems based on our current understanding of systems and also how all these together can help us make a difference in the lives of farmers and the poor.”

Mechanization is a process of introducing technology or farm equipment to increase field efficiency. CIMMYT’s mechanization work is context-specific, to help farmers have access to the appropriate tools that are new, smart and ideal for their unique farming conditions.
Jelle Van Loon, CIMMYT mechanization specialist, explains how his team prototypes innovations that allow precision farming and supports different actors in the value chain from importers to policy-makers to create broader availability of farm equipment.
Wheat provides, on average, 20% of the calories and protein for more than 4.5 billion people in 94 developing countries. To feed a growing population, we need both better agronomic practices and to grow wheat varieties that can withstand the effects of climate change and resist various pests and diseases.
Watch CIMMYT Wheat Physiologist Carolina Rivera discuss — in just one minute — choosing and breeding desirable wheat traits with higher tolerance to stresses.
This month, the world’s eyes are upon global leaders gathered in Madrid for COP25 to negotiate collective action to slow the devastating impacts of climate change.
According to the UN, the world is heading for a 3.2 degrees Celsius global temperature rise over pre-industrial levels, leading to a host of destructive climate impacts, including hotter and drier environments and more extreme weather events. Under these conditions, the world’s staple food crops are under threat.
A new video highlights the work of the Heat and Drought Wheat Improvement Network (HeDWIC), a global research and capacity development network under the Wheat Initiative, that harnesses the latest technologies in crop physiology, genetics and breeding to help create new climate-resilient wheat varieties. With the help of collaborators and supporters from around the world, HeDWIC takes wheat research from the theoretical to the practical by incorporating the best science into real-life breeding scenarios.
The United Nations Framework Convention on Climate Change estimates that temperatures in Africa are set to rise significantly in coming years, with devastating results for farmers. Some regions could experience two droughts every five years, and see drastic reductions in maize yields over the next three decades.
Research demonstrates that climate-smart agriculture (CSA) is good method of mitigating the effects of climate change, for both farmers and the planet. Associated practices, which increase soil moisture levels and soil biodiversity have been shown to decrease soil erosion by up to 64%. They also have the potential to increase maize yields by 136% and incomes in dry environments by more than twice as much.
However, adoption rates remain low in some of the countries which stand to benefit the most, such as Malawi, Zambia and Zimbabwe, where the adoption of complete conservation agriculture systems is currently at 2.5%.
A new series of infographics describes some of the farming constraints will have to be addressed in order to scale climate-smart agricultural practices successfully in the region, taking into account both benefits and challenges for farmers.

Norman Borlaug was awarded the Nobel Peace Prize in 1970 in recognition of his contributions to world peace through increasing food production. In the latest episode of the BBC radio show Witness History, Rebecca Kesby interviews Ronnie Coffman, student and friend of Norman Borlaug.
Among other stories, Coffman recalls the moment when Borlaug was notified about the Nobel Prize — while working in the wheat fields in Mexico — and explores what motivated Borlaug to bring the Green Revolution to India.
Join us on this visual journey across Ethiopia, Kenya, Malawi and Zimbabwe, where you will meet farmers who demonstrate every day what it means to be RURAL: Resilient, United, Reaping benefits, Adopter and Learner.
These women have adopted climate-smart practices in their production systems to ensure optimal yields while learning about drought-tolerant varieties of maize to counter the harsh effects of dry spells, heat stress, pests and diseases. These rural women are exemplary leaders in their communities, as evidenced by their successful farming practices and the food and income they secure for their families.
Farming families in southern Africa are confronted with the adverse effects of climate change, particularly in Malawi, Mozambique and Zimbabwe. A report by FEWS NET indicates negative impacts like declining yields, increase in grain prices during peak lean seasons and widespread food insecurity. However, Lughano Mwangonde from Malula, southern Malawi, has been practicing climate-smart agriculture since 2004 through a CIMMYT project, which has improved the food security of her family. In the midst of increasing climate variability, Lughano is cushioned against the harsh effects of droughts and heavy downpours through the practices she adopted. For example, she uses crop rotation of maize and legumes, like cowpea and pigeon pea.
Climate change affects men and women differently. Rural women farmers tend to be more susceptible to drought and the additional labor associated with household tasks. As such, building resilience against climate change is critical. For Sequare Regassa, in Ethiopia’s Oromia region, this means shifting to drought-tolerant maize varieties such as BH661, which have better performance and increased yield, even under heat and other stress conditions.
Sequare Regassa is the family’s breadwinner, looking after her four children and working closely with her extended family on their 8-hectare farm in Ethiopia’s Oromia region. “Getting a good maize harvest every year, even when it does not rain much, is important for my family’s welfare,” she says. Although her children are now grown and living with their own families, the family farm unites them all in producing adequate grain to feed themselves. Read more about how Regassa and other farmers are weatherproofing their livelihoods.
Rural women farmers are taking up improved drought-tolerant and high yielding varieties with early maturity thanks to participatory maize varietal selection. “If I am able to harvest in three and a half months or less, compared to four months or more for other varieties, I can sell some grain to neighbors still awaiting their harvest who want to feed their families,” says Tabitha Kamau. She is a smallholder farmer in Machakos County, Kenya, who plants drought-tolerant maize on her plot. Read about how farmers in her area are choosing the varieties that work best for them.
Rose Aufi explains how her family of seven children and three grandchildren are food-secure thanks to the climate-smart agriculture techniques she practices on her farm in Matandika, southern Malawi. She and her husband have obtained a good harvest since they started participating in a CIMMYT project and adopted climate-smart agricultural practices. Aufi says technologies such as mulching and crop rotation are there to simplify the workload in the field.
Dolly Muatha, a 49-year-old farmer with four children in Kenya’s Makueni County, has been growing SAWA drought-tolerant maize for three years. She has witnessed the performance of this variety in her demo plot. “It matures early and yields two to three beautiful cobs per plant” she says.
Ruth Kanini Somba adopted SAWA maize in 2017 after seeing a demonstration plot at Dolly Muatha’s farm. She points out that SAWA performs better than other varieties because of its early maturity and resistance to grey leaf spot and weevils. The drought-tolerant attribute of the SAWA maize also makes the maize crop cope well when rainfall is erratic.
Improved agricultural techniques, such as optimum spacing, enables farmers such as Agnes Nthambi to get better crops. This farmer from Kenya’s Machakos County hosted a demonstration plot she and other farmers in her area were able to learn new growing techniques. “On this trial, I learned that spacing was about two times shorter than we are generally used to. Even with the more constricted spacing, the maize has performed much better than what we are used to seeing,” Nthambi explained.
MARPLE (Mobile and Real-time PLant disEase) Diagnostics is a revolutionary mobile lab developed by a team from the John Innes Centre (JIC), the International Maize and Wheat Improvement Center (CIMMYT) and the Ethiopian Institute of Agricultural Research (EIAR). It uses nanopore sequence technology to rapidly diagnose and monitor wheat rust in farmers’ fields.
Designed to be used without constant electricity and in varying temperatures, the suitcase-sized lab allows researchers to identify wheat rust to strain level in just 48 hours — something that used to take months using other tools.
The MARPLE team was recognized as Innovator of the Year for international impact in 2019 by the UK Biotechnology and Biological Sciences Research Council (BBSRC).
A new video from the John Innes Centre shows how the MARPLE Diagnostics kit will allow Ethiopia to quickly identify wheat rust strains, instead of sending samples to labs abroad.
How can social protection programs be truly inclusive? Taking a social inclusion lens to agricultural development means looking beyond gender to other identity markers and changing the narratives in gender development approaches, which often place a disproportionate burden on women. Social protection programs do not always keep up with the changes of the traditional gender order.
In this episode, we talk to Juan Gonzalo Jaramillo Mejia, Project Manager and Researcher on Inclusion Innovation and Social Protection. He discusses why we must engage men in the fight for gender equality and how using a social inclusion lens to social protection programs is necessary to ensure that no one is left behind.

Demand for wheat is predicted to increase 70% by the year 2050. As demand for wheat is increasing, so are challenges to wheat production. New and more aggressive pests and diseases, diminishing water resources, limited available land, and unstable weather conditions due to climate change present risks for the crop.
Carolina Rivera is working to solve this problem. A wheat physiologist at CIMMYT and data coordinator with the International Wheat Yield Partnership, she works to identify new traits in wheat aiming to boost grain number and yield. Rivera is also one of the recipients of the 2019 Jeanie Borlaug Laube Women in Triticum Early Career Award.

The International Maize and Wheat Improvement Center (CIMMYT) operates five agricultural experiment stations in Mexico. Strategically located across the country to take advantage of different growing conditions — spanning arid northern plains to sub-tropical and temperate climatic zones — the stations offer unique and well-managed testing conditions for a variety of biotic and abiotic stresses.
Heat and drought tolerance in wheat is the focus of study at Ciudad Obregón, while the humid, cool conditions at Toluca are ideal for studying wheat resistance to foliar diseases. The tropical and sub-tropical settings of Agua Fría and Tlaltizapán respectively are suited to maize field trials, while at El Batán researchers carry out a wide variety of maize and wheat trials.
A new video highlights the important and valuable contribution of the five experimental stations in Mexico to CIMMYT’s goal of developing maize and wheat that can cope with demanding environments around the world, helping smallholder farmers in Africa, Asia and Latin America adapt to challenges like climate change, emerging pests and disease, and malnutrition.
Featuring aerial cinematography and interviews with each station’s manager, the video takes viewers on a journey to each experimental station to highlight the research and management practices specific to each location.
In addition to their role in breeding maize and wheat varieties, CIMMYT’s experimental stations host educational events throughout the year that train the next generation of farmers, policymakers and crop scientists. They also provide the canvas on which CIMMYT scientists develop and test farming practices and technologies to help farmers grow more with less.
Some of the stations also hold historical significance. Ciudad Obregón and Toluca are two of the sites where Norman Borlaug set up his shuttle breeding program that provided the foundations of the Green Revolution. It was also in Toluca, while at a trial plot alongside six young scientists from four developing nations, where Borlaug first received news of his 1970 Nobel Peace Prize award.
The maize seed sector in east and southern Africa is male-dominated. However, there are women working in this sector who are breaking social barriers and helping to improve household food security, nutrition and livelihoods by providing jobs and improved seed varieties to farmers.
Researchers from the International Maize and Wheat Improvement Center (CIMMYT) conducted interviews with women owners of seed companies in eastern and southern Africa. They shared information on their background, their motivation to start their businesses, what sets their companies apart from the competition, the innovative approaches they use to ensure smallholder farmers adopt improved seed varieties, the unique challenges they face as women in the seed sector and the potential for growth of their companies.
Pollution has become a part of our daily life: particulate matter in the air we breathe, organic pollutants and heavy metals in our food supply and drinking water. All of these pollutants affect the quality of human life and create enormous human costs.
India is home to 15 of the world’s cities with the highest air pollution, making it a matter of national concern. The country is the world’s third largest greenhouse gas emitter, where agriculture is responsible for 18% of total national emissions.
For decades, CIMMYT has engaged in the development and promotion of technologies to reduce our environmental footprint and conserve natural resources to help improve farmer’s productivity.
Efficient use of nitrogen fertilizers, better management of water, zero-tillage farming, and better residue management strategies offer viable solutions to beat air pollution originating from the agriculture sector. Mitigation measures have been developed, field tested, and widely adopted by farmers across Bangladesh, India, Nepal and Pakistan.
“Multi-lateral impacts of air pollution link directly it to various sustainability issues,” explained Balwinder Singh, Cropping Systems Simulation Modeler at CIMMYT. “The major sustainability issues regarding air quality revolve around the common question: How good is good enough to be sustainable? We need to decide how to balance the sustainable agriculture productivity and hazardous pollution levels. We need to have policies on the regulation of crop burning and in addition to policies surrounding methods to help reach appropriate air quality levels.”
