Theme: Nutrition, health and food security

As staple foods, maize and wheat provide vital nutrients and health benefits, making up close to two-thirds of the world’s food energy intake, and contributing 55 to 70 percent of the total calories in the diets of people living in developing countries, according to the U.N. Food and Agriculture Organization. CIMMYT scientists tackle food insecurity through improved nutrient-rich, high-yielding varieties and sustainable agronomic practices, ensuring that those who most depend on agriculture have enough to make a living and feed their families. The U.N. projects that the global population will increase to more than 9 billion people by 2050, which means that the successes and failures of wheat and maize farmers will continue to have a crucial impact on food security. Findings by the Intergovernmental Panel on Climate Change, which show heat waves could occur more often and mean global surface temperatures could rise by up to 5 degrees Celsius throughout the century, indicate that increasing yield alone will be insufficient to meet future demand for food.

Achieving widespread food and nutritional security for the world’s poorest people is more complex than simply boosting production. Biofortification of maize and wheat helps increase the vitamins and minerals in these key crops. CIMMYT helps families grow and eat provitamin A enriched maize, zinc-enhanced maize and wheat varieties, and quality protein maize. CIMMYT also works on improving food health and safety, by reducing mycotoxin levels in the global food chain. Mycotoxins are produced by fungi that colonize in food crops, and cause health problems or even death in humans or animals. Worldwide, CIMMYT helps train food processors to reduce fungal contamination in maize, and promotes affordable technologies and training to detect mycotoxins and reduce exposure.

On December 5, we celebrate World Soil Day. This year the theme is “Be the solution to soil pollution.” Most of you may not have been aware that such a day even existed or perhaps even question the reason why the world even dedicates an entire day to celebrate soil. The authors of this article are soil scientists; we have devoted our professional careers to studying soil. Perhaps we are biased, but we use this opportunity to enlighten readers with a greater appreciation for the importance of this thin layer of our planet we call soil.

Humankind has a conflicting relationship with soil. In English, “dirt” and “dirty” are synonyms for unclean, calling a man or a woman “dirty” is a terrible insult. A baby’s dirty diapers are said to be “soiled.” But if we dig deeper into human consciousness, we find a different story.

For Hindus, the Panchtatva defines the universal laws of life. Everything, including life, is composed of five basic elements: Akash, space or sky; Vayu, air; Jal, water; Agni, fire; and Prithvi, earth or soil. In the Judeo-Christian tradition, the first two human beings on the planet were Adam and Eve. In Hebrew, the original language of the Bible’s Old Testament, the name Adam means “earth” or “soil” and Eve means “life.” These images and symbols portray that human life originally derived from soil.

It gets even deeper: The English terms “human” and “humanity” are rooted in the Greek word “humus,” the fertile black topsoil.

When we use the words “soil” and “dirt” as derogatory terms, we literally define ourselves as soil. Soil is important and here are a few reasons why.

Soil is absolutely critical for the survival of our species and of all living life on the planet. Over 90 percent of all food produced in the world comes from soil and a greater percentage of the world’s freshwater passes through soil.

Arguably, climate change is the greatest threat to our species. Despite mitigation efforts by the global community, soil is frequently forgotten. However, soil holds roughly two and a half times the amount of carbon held in the atmosphere and in all of the plants and animals combined.

Soil is also the greatest reservoir of biodiversity on the planet. In one pinch of soil, there are over 1 billion individual organisms and 1 million unique species, most of which we know almost nothing about. In one handful of soil, there are more living organisms than the total number of human beings that have ever walked on the planet. As all of our antibiotics have been derived from soil microorganisms, the secrets to fighting all kinds of diseases are just under your feet.

In Nepal, soil is deeply interrelated with culture. From birth to death, Nepalese use soil in many rituals: naming ceremonies, birthday celebrations, soiling on Ashar 15, local healing and medicine, etc.

The government of Nepal has set ambitious targets for increasing the levels of organic matter in soil. This is essential to ensure that the soils that have sustained Nepali civilization for centuries will continue to sustain future generations. We need to encourage farmers and land managers in Nepal to maintain terracing on steeply sloped lands to protect against soil erosion. It is also important to appropriately use agrochemicals, such as pesticides and inorganic fertilizers, to improve soil health and crop productivity.

Soil has been polluted by heavy metals, effluents from chemical industries, indiscriminate use of agrochemicals, urbanization without proper planning, networking of roads without considering the carrying capacity of the soil and other factors. So let’s not overlook the importance of soil. We need to value the cleansing properties of soil, particularly riverine soils, and prevent these areas from continuing as the dumping grounds and sewers of Kathmandu and other cities.

On this day, the day when we celebrate soil, take a moment to look under your feet and marvel at the beauty and complexity of soil.

If we take care of our soils, our soils will take care of us.

New digital maps to support soil fertility management in Nepal

KATHMANDU, Nepal (CIMMYT) — The International Maize and Wheat Improvement Center (CIMMYT) is working with Nepal’s Soil Management Directorate and the Nepal Agricultural Research Council (NARC) to aggregate historic soil data and, for the first time in the country, produce digital soil maps. The maps include information on soil PH, organic matter, total nitrogen, clay content and boron content. Digital soil mapping gives farmers and natural resource managers easy access to location-specific information on soil properties and nutrients, so they can make efficient and localized management decisions.

As part of CIMMYT’s Nepal Seed and Fertilizer (NSAF) project, researchers used new satellite imagery that enabled the resolution of the maps to be increased from 1×1 km to 250×250 m. They have updated the web portal to make it more user friendly and interactive. When loaded onto a smartphone, the map can retrieve the soil properties information from the user’s exact location if the user is within areas with data coverage. The project team is planning to produce maps for the whole country by the end of 2019.

CIMMYT scientist David Guerena talks about the role of the new digital maps to combat soil fertility problems in Nepal.

At a World Soil Day event in Nepal, CIMMYT soil scientist David Guerena presented the new digital soil maps to scientists, academics, policymakers and other attendees. Guerena explained the role this tool can play in combatting soil fertility problems in Nepal.

These interactive digital maps are not simply visualizations. They house the data and analytics which can be used to inform site-specific integrated soil fertility management recommendations.

The first high-resolution digital soil maps for the Terai region have been produced with support from the data assets from the National Land Use Project, developed by Nepal’s Ministry of Agriculture and Livestock Development. These maps will be used to guide field programming of the NSAF project, drive the development of market-led fertilizer products, and inform and update soil management recommendations. The government of Nepal can use the same information to align policy with the needs of farmers and the capacity of local private seed and fertilizer companies.

In 2017, 16 scientists from Nepal’s Soil Management Directorate, NARC and other institutions attended an advanced digital soil mapping workshop where they learned how to use different geostatistical methods for creating soil maps. This year, as part of the NSAF project, four NARC scientists attended a soil spectroscopy training workshop and learned about digitizing soil data management and using advanced spectral methods to convert soil information into fertilizer recommendations.

Soil data matters

Soil properties have a significant influence on crop growth and the yield response to management inputs. For farmers, having access to soil information can make a big difference in the adoption of integrated soil fertility management.

Farmer motivation and decision-making relies heavily on the perceived likeliness of obtaining a profitable return at minimized risk. This largely depends on the yield response to management inputs, such as improved seeds and fertilizers, which depends to a large extent on site-specific soil properties and variation in agro-ecological conditions. Therefore, quantitative estimates of the yield response to inputs at a given location are essential for estimating the risks associated with these investments.

The digital soil maps can be accessed at https://nsafmap.github.io/.

The Nepal Seed and Fertilizer project is funded by the United States Agency for International Development (USAID) and is a flagship project in Nepal. The objective of the NSAF is to build competitive and synergistic seed and fertilizer systems for inclusive and sustainable growth in agricultural productivity, business development and income generation in Nepal.

New Soil Intelligence System for India provides high-quality data using modern analytics

NEW DELHI (CIMMYT) — The new Soil Intelligence System (SIS) for India will help the states of Andhra Pradesh, Bihar and Odisha rationalize the costs of generating high-quality soil data and build accessible geospatial information systems based on advanced geostatistics. The SIS initiative will rely on prediction rather than direct measurements to develop comprehensive soil information at scale. The resulting data systems will embrace FAIR access principles — findable, accessible, interoperable, and reproducible — to support better decision-making in agriculture.

SIS is a $2.5 million investment funded by the Bill & Melinda Gates Foundation. This initiative is led by the International Maize and Wheat Improvement Center (CIMMYT), in collaboration with numerous partners including the International Food Policy Research Institute (IFPRI), World Soil Information (ISRIC), the Andhra Pradesh Space Applications Center (APSAC), and the state governments and state agriculture universities of Andhra Pradesh and Bihar. The initiative runs from September 2018 through February 2021.

“SIS will make important contributions towards leveraging soil information for decision-making in Indian agriculture by devising new soil health management recommendations,” explained Andrew McDonald, CIMMYT’s Regional Team Leader for Sustainable Intensification and Project Leader for the Cereal Systems Initiative for South Asia (CSISA). Researchers and scientists will combine mapping outputs with crop response and landscape reconnaissance data through machine-learning analytics to derive precise agronomy decisions at scale.

Farmers will be the primary beneficiaries of this initiative, as they will get more reliable soil health management recommendations to increase yields and profits. SIS will also be useful to state partners, extension and agricultural development institutions, the private sector and other stakeholders who rely on high-quality soil information. Through SIS, scientists and researchers will have an opportunity to receive training in modern soil analytics.

The SIS initiative aims to facilitate multi-institutional alliances for soil health management and the application of big data analytics to real-world problems. These alliances will be instrumental for initiating broader discussions at the state and national levels about the importance of robust data systems, data integration and the types of progressive access policies related to ‘agronomy at scale’ that can bring India closer to the Sustainable Development Goals.

Better soil analysis

Spectroscopy enables precise soil analysis and can help scientists identify appropriate preventive and rehabilitative soil management interventions. The technology is also significantly faster and more cost-effective than wide-scale wet chemistry-based soil analysis.

As part of the CSISA project, led by CIMMYT and funded by the Bill & Melinda Gates Foundation, two new soil spectroscopy labs were recently set up in Andhra Pradesh and Bihar, in collaboration with the state departments of agriculture. One lab is now operating at the Regional Agricultural Research Station (RARS) in Tirupati, Andhra Pradesh; and the other one at Bihar Agricultural University (BAU Sabour), in Bhagalpur, Bihar.

“The support from CIMMYT through the Gates Foundation will contribute directly to bringing down the cost of providing quality soil health data and agronomic advisory services to farmers in the long run,” said K.V. Naga Madhuri, Principal Scientist for Soil Science at Acharya N. G. Ranga Agricultural University. “We will also be able to generate precise digital soil maps for land use planning. The greatest advantage is to enable future applications like drones to use multi-spectral imagery and analyze rapidly large areas and discern changes in soil characteristics in a fast and reliable manner.”

Under the SIS initiative, soil spectroscopy results will be validated with existing gold standard wet chemistry methods. They will also be integrated with production practice data collected from the ground level, through new statistical tools.

Precise predictive models

Drawing information from a limited number of soil observations from a sample dataset, digital soil mapping (DSM) uses (geo)statistical models to predict the soil type or property for locations where no samples have been taken.

“These ‘unsampled locations’ are typically arranged on a regular grid,” explained Balwinder Singh, CIMMYT scientist and Simulation Modeler, “so DSM produces gridded — raster — soil maps at a specific spatial resolution — grid cell or pixel size — with a spatial prediction made for each individual grid cell.”

“Adopting DSM methods, combined with intelligent sampling design, could reduce the strain on the soil testing system in terms of logistics, quality control and costs,” noted Amit Srivastava, a geospatial scientist at CIMMYT. “Improving digital soil mapping practices can also help create the infrastructure for a soil intelligence system that can drive decision-making at scale.”

In partnership with state government agencies and the Bill & Melinda Gates Foundation, CIMMYT will continue to support the expansion of digital soil mapping and soil analysis capacity in India. The CSISA project and the SIS initiative are helping to deliver soil fertility recommendations to farmers, an important step towards the sustainable intensification of agriculture in South Asia.

CIMMYT drought tolerant maize: A key innovation for millions of farmers, says FAO

As climate experts forecast another climate-warming El Nino in early 2019, maize varieties developed under the Drought Tolerant Maize for Africa (DTMA) initiative represent low-cost innovations that could improve the crop’s climate resilience and the livelihoods of millions family farmers across Africa, according to the UN Food and Agriculture Organization (FAO).

Drought tolerant (DT) maize was among 20 success stories featured at the Innovation Fair of the International Symposium on Agricultural Innovation for Family Farmers, organized and hosted by FAO in Rome from 21 to 23 November, 2018. Drawing more than 500 participants from farmer associations, international organizations, United Nations agencies, governments, research institutions and the private sector, the Fair aimed to devise and recommend actions that unlock the potential of agricultural innovation.

Drought-tolerant seeds: An affordable and effective way to cope with dry weather

‘’Since early 1990s, farmers in Zimbabwe face erratic rains and maize crops often fail due to frequent droughts,’’ said Cosmos Magorokosho, maize breeder based at the Harare, Zimbabwe, office of the International Maize and Wheat Improvement Center (CIMMYT).

Led by CIMMYT, funded by the Bill & Melinda Gates Foundation and the Howard Buffett Foundation, and involving 13 national maize breeding programs and various seed companies across Africa, DTMA is responsible for more than 160 new maize varieties, including 15 in Zimbabwe that yield 25 to 30 percent more than conventional varieties under dry conditions and perform as well as those varieties under normal rainfall. The latter was crucial for convincing seed companies to take up and market DT maize, according to Magorokosho.

In one study in drought-prone southern Zimbabwe, farmers using the DT varieties in dry years were able to harvest up to 600 kilograms more maize per hectare — worth $240 and enough maize for 9 months for an average family of 6 people — than farmers who sowed conventional varieties. The added food security comes at no additional cost and, if farmers choose to sell the grain, it brings extra income for other household needs.

Under the Stress Tolerant Maize for Africa initiative, CIMMYT and partners are continuing to develop maize varieties that cope not only with drought but with common constraints such as insect pests, diseases including Maize Lethal Necrosis and infertile soils.

Public-private partnerships enable demand-driven innovation

Adopting new technology or practices can represent unacceptable risks for resource-poor farming families, who live without the official safety nets enjoyed by peers in prosperous economies and will simply starve if their crops fail. Involving farmers, seed companies and other end users in development is essential for agricultural innovations to be widely adopted and sustainable, according to Bram Govaerts, global director of innovative business strategies at CIMMYT.

“Dialogue with global food processing companies can create market opportunities for smallholder farmers through approaches like local, responsible sourcing,’’ said Govaerts, speaking during the fair’s panel ‘Engaging the private sector to accelerate agricultural innovation.’

“More than 3,300 Mexican farmers on more than 35,000 hectares in 5 states will benefit from responsible sourcing arrangements, whereby the companies pay them to grow the grain using sustainable farming practices,” Govaerts explained, adding that the farmers will supply an estimated 400,000 tons of grain to participating companies in the next 3 to 5 years.

Mexico’s Agriculture Department (SAGARPA) supports these and other public-private partnerships through its investments in MasAgro, which studies, develops and transfers innovative farming practices and technologies to the field, with emphasis on family farmers.

In September, the FAO’s Regional Office for Latin America and the Caribbean acknowledged MasAgro as a replicable and scalable initiative that could contribute significantly to sustainable rural development in that region.

These two impactful examples show that agricultural innovation can only succeed through well-thought research and development partnerships, and building such collaborations is a science in itself.

How does CIMMYT's improved maize get to the farmer?

Breaking Ground: Huihui Li links new genetic knowledge with crop breeding

Postcard_Huihui Li Breaking Ground

DNA is often referred to as the blueprint for life. It contains codes to make the proteins, molecules and cells essential for an organism’s growth and development. Over the last decade, scientists have been figuring out how specific sections of DNA in maize and wheat are associated with physical and genetic traits, such as grain size and drought resistance.

Quantitative geneticist Huihui Li with the International Maize and Wheat Improvement Center (CIMMYT) helps link this new genetic knowledge with traditional crop breeding, to speed up the development of improved maize and wheat varieties. Li’s research uses cutting-edge genomics, computational biology and statistical tools to turn data into useful information for plant breeders.

“Breeders always accumulate big amounts of data, most of the time they need efficient tools to mine the stories from this data. That’s part of our job in the Biometrics and Statistics Unit,” she explained.

Her research helps breeders more quickly and accurately predict which maize and wheat varieties in the CIMMYT gene bank have the traits they seek to create improved varieties. For example, if a plant breeder wanted to develop a hybrid maize variety with high protein levels and pest resistance, Li could help by identifying which parental varieties would have these traits.

It takes about ten years for crop breeders to develop a new hybrid. Removing some of the guesswork during the early stages of their experiments could reduce this time significantly. With increasing environmental pressures from climate change and population growth, releasing better crop varieties more quickly will be vital to ensure there is enough food in the future.

Li says her family and experience growing up in China greatly influenced her career choice.

“Through my grandfather’s experience as the head of the Bureau of Agriculture and Forestry, I learned that there were many people in China suffering from hunger, poverty and malnutrition,” she said.

Li realized that these issues were prevalent throughout the developing world when her mother left China for two years to serve as a foreign aid doctor in Cameroon.

“As a ten-year-old girl, I told myself that I should make my contribution to reduce hunger and poverty, and improve human nutrition in the future,” Li recalled. “I always ask myself, ‘What’s my value to humanity?”

She studied bio-mathematics and quantitative genetics at Beijing Normal University and Cornell University before joining CIMMYT in 2010 as a consultant.

“I wanted to join CIMMYT because it works throughout the developing world to improve livelihoods and foster more productive, sustainable maize and wheat farming,” Li explained. “Also, CIMMYT provided a platform where I could collaborate with scientists worldwide and receive academic and career-boosting trainings.”

She became staff in 2012 and is currently based out of the CIMMYT office in Beijing. In addition, Li is an adjunct associate professor with the Chinese Academy of Agricultural Sciences (CAAS). She helps CAAS scientists improve their experimental design and better incorporate genetic information into their crop breeding.

“I love doing research,” Li said. “I’m a curious person so if I can solve a problem, I feel very happy, but I really want my research to have value – not just for myself – but for the world.”

Huihui Li’s work contributes to Seeds of Discovery (SeeD), a multi-project initiative comprising: MasAgro Biodiversidad, a joint initiative of CIMMYT and the Mexican Ministry of Agriculture, Livestock, Rural Development, Fisheries and Food (SAGARPA) through the MasAgro (Sustainable Modernization of Traditional Agriculture) project and the CGIAR Research Programs on Maize (MAIZE) and Wheat (WHEAT).

Let’s make hunger history

KATHMANDU, Nepal — I feel humbled and honored to have been chosen for the 2018 MAIZE-Asia Youth Innovators Award. I want to thank my father and brother for never clipping my wings and letting me fly high. I want to thank my mother, who despite having no education, not being able to read or write a single word, dreamed of having a scientist daughter. Everyone has a story and this is mine.

Due to my family’s poverty and the hardships faced during the civil war in Nepal, I had to leave school at grade 5 and was compelled to work as child labor in a local hotel to meet my family’s daily needs. I remember those difficult months where I used to cry every day, as the hotel was right across from the school and I wanted to study so badly but I was deprived from education due to my family’s condition. My life changed when a mountain climber staying at the hotel heard my story and generously decided to pay my school fees. I would go on to graduate top of my class.

Everyone has challenges. It is my dream to dedicate my life to fight the greatest challenge of all: hunger.

The amount of undernourished people in the world has been increasing. According to the Food and Agriculture Organization of the United Nations (FAO), over 820 million people face chronic food deprivation. Many of these people live in developing countries, including my home country, Nepal. About 6 million people, which is about 23% of Nepal’s population, are undernourished. Moreover, half of children under the age of five suffer from malnutrition in Nepal.

Increasing agricultural production, gender equity and awareness is crucial to meet sustainable development goals by 2030. As an agricultural student, I chose to focus on maize-based systems, as maize is a staple food crop and a major component of feed and fodder for farm animals. It is the second major crop in Nepal after rice — first in the hill region of Nepal — and can be a backbone for food security and a good source of income for resource-poor farmers.

Demand for maize is growing in Nepal, but production has remained stagnant. This is partly due to lack of knowledge on proper nutrient management and fertilizer use. In addition, due to the economic situation in Nepal, many men have been forced to migrate to find work and support their families, which has led to an increased “feminization” of agriculture. However, female farmers frequently have less access to information and resources that would help them to increase yields.

Since my undergraduate degree, I have carried out research on nutrient management in maize in the Eastern Terai region of Nepal, particularly focusing on women, to increase the maize production and income of smallholder farmers. My research involved the use of Nutrient Expert, a dynamic nutrient management tool based on site-specific nutrient management principles, to increase maize production and enhance soil quality without negatively affecting the environment. Regional fertilizer recommendations are often too broad and cannot take into account the soil quality of individual farmers’ field, as it varies greatly among fields, seasons and years. Applying the incorrect amount of fertilizer is costly to farmers and can negatively affect the environment and crop yields.

The Nutrient Expert app rapidly provides farm-specific fertilizer recommendations for nitrogen, phosphorus and potassium for crops in the presence or absence of soil testing results, contributing to dynamic nutrient management, increased productivity and net returns from crops for farmers. In the meantime, it helps to decrease the nitrogen and phosphorous leaching from the soil into rivers, which protects the water ecosystem both in wetlands and oceans. This technology is sustainable because it optimizes the use of nutrients in the soil for higher productivity and prevents the overuse of fertilizer. It decreases the farmer’s cost of production and is environmentally friendly. Further, my research showed that Nutrient Expert helped farmers to produce 86.6% more maize grain than their previous fertilizer practice.

Proper nutrient management is just one of the challenges facing agriculture today. To address these challenges and to create a world without hunger it is extremely important to work with and include young people. Effective extension tools to train and motivate young minds in research and create more interest in maize-based systems and farming is necessary for the overall adoption and proper utilization of improved varieties and technologies.

Samjhana Khanal was recently awarded the 2018 MAIZE-Asia Youth Innovators Award from the CGIAR Research Program on Maize (MAIZE) in the category of “Change Agent” for her research on the productivity and profitability of hybrid maize in Eastern Terai, Nepal. Using Nutrient Expert, a decision support tool, individual maize farmers can get specific soil nutrition and fertilizer recommendations, resulting in higher grain yield, productivity and profits.

An agricultural graduate, Khanal has founded and co-founded several local social organizations in Nepal to involve young minds in the development of innovative strategies to work towards sustainable agriculture and zero hunger. Her organizations support more than 285 households with community microfinance, help resource-poor farmers and assist women farmers.

The MAIZE-Asia Youth Innovators Awards aim to celebrate youth participation in maize-based agri-food systems and are sponsored by the CGIAR Research Program on Maize (MAIZE) in collaboration with Young Professionals for Agricultural Development (YPARD).

Q&A: Expanding CIMMYT’s research agenda on markets and business

TEXCOCO, Mexico (CIMMYT) — Food security is heavily dependent on seed security. Sustainable seed systems ensure that a variety of quality seeds are available to farming communities at affordable prices. In many developing countries, however, farmers still lack access to the right seeds at the right time.

In the past, governments played a major role in getting improved seed to poor farmers. These days, however, the private sector plays a leading role, often with strong support from governments and NGOs.

“Interventions in formal seed systems in maize have tended to focus on improving the capacity of seed producing companies, which are often locally owned small-scale operations, to produce and distribute quality germplasm,” says Jason Donovan, Senior Economist at International Maize and Wheat Improvement Center (CIMMYT). “These local seed companies are expected to maintain, reproduce and sell seed to underserved farmers. That’s a pretty tall order, especially because private seed businesses themselves are a fairly new thing in many countries.”

Prior to the early 2000s, Donovan explains, many seed businesses were partially or wholly state-owned. In Mexico, for example, the Instituto Nacional de Investigaciones Forestales, Agrícolas y Pecuarias (INIFAP) produced seed and supplied it to a market-oriented entity which was responsible for distribution. “What we’re seeing now is locally owned private seed businesses carving out their space in the maize seed market, sometimes in direct competition with multinational seed companies,” he says. In Mexico, around 80 locally owned maize seed producing businesses currently exist, most of which have been involved in CIMMYT’s MasAgro Maize project. These are mostly small businesses selling between 150,000 and 500,000 kg of hybrid maize per year.

In the following Q&A, Donovan discusses new directions in research on value chains, the challenges facing private seed companies, and how new studies could help understand their capacities and needs.

How does research on markets and value chains contribute to CIMMYT’s mission?

We’re interested in the people, businesses and organizations that influence improved maize and wheat seed adoption, production, and the availability and quality of maize and wheat-based foods. This focus perfectly complements the efforts of those in CIMMYT and elsewhere working to improve seed quality and increase maize and wheat productivity in the developing world.

We are also interested in the nutrition and diets of urban and rural consumers. Much of the work around improved diets has centered on understanding fruit and vegetable consumption and options to stimulate greater consumption of these foods. While there are good reasons to include those food groups, the reality is that those aren’t the segments of the food market that are immediately available to or able to feed the masses. Processed maize and wheat, however, are rapidly growing in popularity in both rural and urban areas because that’s what people want and need to eat first. So the question becomes, how can governments, NGOs and others promote the consumption of healthier processed wheat and maize products in places where incomes are growing and tastes are changing?

This year, CIMMYT started a new area of research in collaboration with A4NH, looking at the availability of processed maize and wheat products in Mexico City — one of the world’s largest cities. We’re working in collaboration with researchers form the National Institute of Public Health to find out what types of wheat- and maize-based products the food industry is selling, to whom, and at what cost. At the end of the day, we want to better understand the variation in access to healthier wheat- and maize-based foods across differences in purchasing power. Part of that involves looking at what processed products are available in different neighborhoods and thinking about the dietary implications of that.

Your team has also recently started looking at formal seed systems in various locations. What direction is the research taking so far?

Our team’s current priority is to advance learning around the private sector’s role in scaling improved maize varieties. We are engaged with three large projects: MasAgro Maize in Mexico, Stress Tolerant Maize for Africa (STMA) and the Nepal Seed and Fertilizer Project (NSFP). We are looking to shed light on the productive and marketing capacities of the privately owned seed producing businesses and their ability to get more seed to more farmers at a lower cost. This implies a better understanding of options to better link seed demand and supply, and the business models that link seed companies with agro-dealers, seed producing farmers, and seed consumers.

We are also looking at the role of agro-dealers — shops that sell agricultural inputs and services (including seed) to farmers — in scaling improved maize seed.

At the end of the day, we want to provide evidence-based recommendations for future interventions in seed sectors that achieve even more impact with fewer resources.

This research is still in its initial stages, but do you already have an idea of what some of the key limiting factors are?

I think one of the main challenges facing small-scale seed producing businesses is the considerable expense entailed in simultaneously building their productive capacities and their market share. Many businesses simply don’t have a lot of capital. There’s also a lack of access to specialized business support.

In Mexico, for example, a lot of people in the industry are actually ex-breeders from government agencies, so they’re very familiar with the seed production process, but less so with options for building viable businesses and growing markets for new varieties of seed.

This is a critical issue if we expect locally owned seed businesses to be the primary vehicle by which improved seeds are delivered to farmers at scale. We’re currently in the assessment phase, examining what the challenges and capacities are, and hopefully this information will feed into new approaches to designing our interventions.

Is the study being replicated in other regions as well?

Yes, in East Africa, under the Stress Tolerant Maize for Africa (STMA) project. We’re working with seed producing businesses and agro-dealers in Ethiopia, Kenya, Tanzania, and Uganda to understand their strategies, capacities, and needs in terms of providing improved seed to more farmers. We’re using the same basic research design in Mexico, and there is also ongoing work in the Nepal Seed and Fertilizer Project. Given that we are a fairly small team within CIMMYT, comparable cross-regional research is one way to punch above our weight.

Why is this research timely or important?

The research is critical as CIMMYT’s impact relies, in part, on partnerships. In the case of improved maize seed, that revolves around viable seed businesses.

Although critical, no one else is actually engaged in this type of seed sector research. There have been a number of studies on seed production, seed systems and the adoption of improved seed by poor farmers. A few have focused on the emergence of the private sector in formal seed systems and the implications for seed systems development, but most have been pretty broad, examining the overall business environment in which these companies operate but not much beyond that. We’re trying to deepen the discussion. While we don’t expect to have all the answers at the end of this study, we hope we can shift the conversation about options for better support to seed companies and agro-dealers.

Matthew Reynolds joins the Mexican Academy of Sciences

EL BATAN, Mexico (CIMMYT) — Mexico’s most prestigious scientific association has welcomed Matthew Reynolds among its regular members after accepting the nomination presented by fellow member, Alfonso Larqué Saavedra from the Yucatan Scientific Research Center.

The Mexican Academy of Sciences is an independent and not-for-profit association formed by acknowledged scientists working in both Mexican and international organizations. Its main objective is to offer expert advice to address the most pressing issues and challenges confronting Mexico’s government and civil society.

“I am deeply honoured to be recognized by the Academy,” Reynolds said. “Mexico has a proud tradition of scientific achievements including those of its pre-Hispanic civilizations, and not least in crop science. It is my hope that I can continue to contribute to Mexican agriculture and capacity building, especially in helping to buffer the effects of climate change. I am also very grateful for my long association with Professor Larqué Saavedra with whom I jointly supervised my first Mexican graduate student at Colpos and who nominated me for this position.”

CIMMYT scientist Matthew Reynolds has been appointed a member of the Mexican Academy of Science.

Reynolds is a Wheat Physiologist at International Maize and Wheat Improvement Center (CIMMYT). His leadership of the Wheat component of the MasAgro project strengthened his nomination to the Academy. In this capacity, he has overseen the publication of 32 peer-reviewed articles in scientific journals that account for the progress achieved in the development of new high-yielding and resilient wheat varieties for Mexico and for other wheat-growing regions in the developing world.

Since 2011, MasAgro Trigo has characterized 71 thousand wheat lines in field trials designed to test yield potential under severe stress caused by heat and drought conditions. As a result, Reynolds and his team have formed the Wheat Yield Collaboration Yield Trial and the Stress Adaptive Traits Yield Nursery, two panels of elite lines that yield more grain in high temperatures and under limited water supply. Mexico’s agricultural research system INIFAP has recently incorporated 42 elite lines from these nurseries into its wheat-breeding program.

Reynolds has also mentored 12 Mexican students who have undertaken postgraduate studies under the supervision of renowned wheat scientists in American, Australian, British, Chilean and Spanish universities. Eight students have already achieved a PhD degree in different areas of wheat research. This new generation of scientists will further contribute to promote science and research in Mexico, one of the Academy’s main objectives.

Ethiopian experts push for wheat self-sufficiency

ADDIS ABABA, Ethiopia (CIMMYT) — Ethiopia’s leading agriculture and policy specialists will craft a new strategy to dramatically raise national wheat production and achieve self-sufficiency for the crop by 2022, at a special conference organized by the Government of Ethiopia and the International Maize and Wheat Improvement Center (CIMMYT) for November 23, 2018.

Annual imports to satisfy Ethiopia’s demand for wheat — one of the country’s four key food crops — now cost more than $600 million and expose national food security to capricious global price shifts for grain, according to Mandefro Nigussie, Director General of the Ethiopian Institute of Agriculture (EIAR).

“Ethiopians now consume some 6.5 million tons per year but the country’s 4.2 million households grow only 4.6 million tons on 1.7 million hectares and demand for the crop is rising, as more people move to cities and change in life style,” Nigussie explained.

National wheat yields are steadily climbing but still average only 2.7 tons per hectare; well below global standards, according to Bekele Abeyo, CIMMYT wheat scientist and Ethiopia country representative.

“There’s great potential to expand irrigated wheat production, especially in the lowlands along the major river basins,” Nigussie said. “In the Ethiopian highlands, wheat’s traditional environment, more farmers need to use high-yielding, disease resistant seed and modern farming practices. Even modest levels of technology adoption can provide yields as high as 4 tons per hectare.” Wheat yield can also be increased significantly by treating acidic soils and by making broad-beds in vertisol soil areas.

Called “Wheat Self-Sufficiency in Ethiopia: Challenges and Opportunities,” the consultative workshop builds on recent successes and lessons in Ethiopia of the Wheat Initiative, an international partnership of private and public organizations that conducts wheat research for food security and to help wheat farmers in diverse environments to improve and stabilize their yields.

To be held in the Hiruy Meeting Hall at the headquarters of the Ethiopian Institute of Agricultural Research (EIAR), Addis Ababa, the event will draw some 70 participants, including representatives of Ethiopia’s ministries of agriculture, EIAR, regional agricultural research institutes, the Ethiopian Seed Enterprise, Oromia Seed Enterprise, and the Agricultural Transformation Agency. Adding their experience and ideas will be experts on wheat trade, irrigation and energy, finance and economic cooperation, along with representatives from the Regional Bureau of Agriculture, millers associations, funding agencies, and global organizations including the International Center for Agricultural Research in the Dry Areas (ICARDA) and the International Food Policy Research Institute (IFPRI).

“Aims will include strengthening wheat research and development partnerships, tapping into policies that foster competitive and profitable wheat farming, and supporting national efforts both to reduce imports and end poverty and food insecurity,” Abeyo explained. Kristie Drucza, Gender and Development Specialist at CIMMYT, also notes that, “We see striking opportunities to raise productivity by empowering women in wheat farming, fostering their access to knowledge, technology, and financial resources and their voice in decision making.”

Ethiopia and CIMMYT. Since 1970, Ethiopian farmers have had access to more than 100 high-yielding bread and durum wheat varieties developed and spread through collaboration among EIAR, Ethiopia’s regional agricultural research institutes, and CIMMYT, whose work has contributed to 70 percent of Ethiopia’s wheat varietal development. Use of these high-yielding, disease resistant varieties, along with supportive government policies and better cropping practices, have caused Ethiopia’s average annual wheat production to grow more than double since the early 2000s.

Comparing apples with apples: Farm economic analysis in Kathmandu

KATHMANDU, Nepal (CIMMYT) — Clear and consistent communication is important in any work, and no less so when you are collaborating to improve farmer livelihoods. CIMMYT and partners in South Asia are therefore facilitating Farm Economic Analysis workshops to ensure that stakeholders from a variety of professions are on the same page when it comes to the terminology of agricultural economics. Fay Rola-Rubzen and Roy Murray-Prior from the University of Western Australia presented the first full day workshop at the National Agricultural Research Council (NARC) campus in Kathmandu on November 1, 2018. Deepak Bhandari and Yuga Nath Ghimire of NARC officiated the event. More than thirty participants from CIMMYT, the Department of Agriculture and NARC attended the training, which included agronomists, agricultural economists, extension officers and research associates.

The workshop series is part of CIMMYT’s Sustainable and Resilient Farming Systems Intensification (SRFSI) project, which aims to reduce poverty in the Eastern Gangetic Plains of Nepal, India and Bangladesh by making smallholder agriculture more productive, profitable and sustainable while safeguarding the environment and involving women.

“The main objective [of the workshops] is to make sure we have the same language and understanding of what we are measuring,” said Rola-Rubzen. “When we go to the field, usually, it may not be the economists gathering the data. It is critical for both economists and non-economists to understand what we are talking about so that we are comparing apples with apples, not apples with oranges.”

Rola-Rubzen and Murray-Prior facilitated a highly specific and tailored training, including engaging the participants in the practical analysis of data collected by SRFSI in the Sunsari district in the eastern Terai of Nepal. Topics covered in the training included gross margin, net revenue and sensitivity analyses, as well as matching analyses to data types.

The workshop was well-received by participants, and will also be conducted in India and Bangladesh to ensure further consistency in communication and to facilitate the cross-country analysis and comparison of data “When we work with economists, it will be easier to understand how they are analyzing their data and making their arguments,” said Sofina Maharjan, assistant research associate for the SRFSI project.

The Sustainable and Resilient Farming Systems Intensification project is funded by the Australian Centre for International Agricultural Research.

Breaking Ground: Susanne Dreisigacker knows wheat inside out

Breaking Ground: Susan DreisigackerEL BATAN, Mexico (CIMMYT) — Through pure coincidence, Susanne Dreisigacker fell into the world of agricultural science and landed in Mexico. Her interest in genetics and biology solidified when she arrived at the International Maize and Wheat Improvement Center (CIMMYT) through the University of Hohenheim in Germany to pursue her PhD work. Impressed by CIMMYT’s scientific endeavors and its mission, she found herself permanently back at the institution in 2005 as a resident scientist. Now, as the head of CIMMYT’s Wheat Molecular Breeding Lab, Dreisigacker ensures that wheat breeders use the appropriate wheat material to conduct gene profiling and genome sequencing.

Dreisigacker works to discover and validate molecular markers, or DNA segments, for traits of interest. This information helps breeders to develop improved crop varieties that feature those traits.

At its core, her position centers on defining best practices for genomic tool application in the wheat breeding program. These genomic tools serve as “…indirect selection criteria to ultimately assist breeders select improved outputs at the molecular level, such as disease resistance and enhanced nutritional quality in wheat,” explains Dreisigacker. Furthermore, her research amasses data on grain yield and its corresponding components — such as grain weight and other difficult traits to tackle in the wheat breeding world — to help breeders stabilize high yield rates.

On average, over 40,000 wheat lines a year are analyzed on behalf of breeders under Dreisigacker’s direction. The ultimate challenge is organizing this massive data outcome to effectively support the breeders.

Working in an environment with interdisciplinary characteristics such as a breeding program, it can be difficult to prioritize which traits merit the bulk of her time. Dreisigacker stresses that teamwork is paramount, from breeders to pathologists to quality specialists, as they all share mutual goals, so their efforts “need to intersect in order to be beneficial.” Dreisigacker enjoys interacting among the disciplines and sharing her work with the international wheat community.

Progress in the application of genomic tools and the push for their usefulness inspires Dreisigacker to continue her work with wheat at CIMMYT. Her work in the laboratory is the backbone of the transmission of better quality germplasm from breeders to farmers. “There is a need to more efficiently integrate gene profiling and genome sequencing into breeding. The transition from upstream genomic research to the processes of application and adaptability are overlooked,” says Dreisigacker.

When she is not looking at wheat at the molecular level, you can find her spending time with her husband and young daughter or teaching exercise classes in CIMMYT’s gymnasium.

Affordable grain drying and storage technologies cut down aflatoxins

NAIROBI, Kenya (CIMMYT) — Smallholder farmers in sub-Saharan Africa lose up to a third of their grain after harvest because they often use poor grain storage technologies and ineffective drying practices. Staples like maize stored on-farm are exposed to infestation by insects and fungi. These can lead to contamination with mycotoxins, in particular aflatoxins, poisonous food toxins produced by Aspergillus fungi.

At high doses, aflatoxins can kill. Prolonged exposure to aflatoxins can impact consumers’ health, suppressing immune systems, hindering child growth and even causing liver cancer. Kenya is a particular hotspot for aflatoxins, as regular studies show widespread contamination along the food chain, from maize grain to milk and meat.

Preliminary findings of a study by USAID-funded Feed the Future Innovation Lab for Food Processing and Post-Harvest Handling (FPL) suggest that innovative low-cost grain drying and storage technologies such as hermetic bags and hygrometers could prevent post-harvest crop losses and harmful aflatoxin contamination.

The initial results were shared at a workshop in Nairobi on October 25, 2018, as part of the FPL project, which aims to develop and disseminate affordable and effective post-harvest technologies suited to the African smallholder farmer. This project is a collaboration between the International Maize and Wheat Improvement Center (CIMMYT), Kenya Agricultural & Livestock Research Organization (KALRO) and Purdue University.

A study conducted between May 2017 and May 2018 in Kiboko, Kenya, compared the performance of various hermetic storage containers and bags by different manufacturers with farmers’ usual storage practices. Researchers measured maize grain quality parameters such as grain damage, weight loss in storage, fungal growth and mycotoxins, food quality and seed germination. The results showed hermetic bags were highly effective in averting grain loss for up to one year.

“If these bags are sealed properly, oxygen cannot get in or out. This creates an anaerobic environment that suffocates grain-damaging insects and prevents fungi from growing” says CIMMYT economist Hugo De Groote.

Making hermetic storage more accessible

The Africa Technical Research Center (ATRC) is involved in the development of some of the hermetic bags that were tested during the study. ATRC director Johnson Odera noted that most of the insect infestations start in the field. “When the farmer harvests and transports the maize home, the grain is already infested,” Odera explained. “The damage can be extensive depending on the level of infestation. One of the ways to minimize the losses, while keeping the food safe for consumption is to use hermetic bags”.

These bags, however, remain largely unavailable to smallholder farmers, according to the study. This is mainly due to farmers’ low awareness levels and the high cost of hermetic bags. Unlike normal storage bags that cost about $0.7 each, hermetic bags retail for $2 to $2.5.

A second study, conducted with maize producers and traders in Kakamega, western Kenya, suggests that dropping prices by 20 percent had the potential to increase sales by 88 percent.

This study further suggested that farmers can benefit a lot from using low-cost hygrometers to accurately measure moisture content in maize. Grain is quickly spoiled by fungi contamination if it is not dry enough when stored. One or two percent lower moisture levels can make a big difference in reducing aflatoxin contamination.

“Farmers could put maize grain samples in a plastic bag and insert low-cost hygrometers to read moisture content after temperature is stabilized in 15 minutes,” says Purdue University professor Jacob Ricker-Gilbert. “They then know if their grain is safe enough for storage or not. However, standard hygrometers cost around $100, which is out of reach for many small farmers.”

Purdue University, CIMMYT and KALRO conducted a market survey in 2017 among maize farmers and traders in Kenya to assess their willingness to buy low-cost hygrometers. The survey found that farmers were willing to pay an average price of $1.21 for a hygrometer, while traders said they would buy at $1.16 each. The project was able to get cheap and reliable hygrometers at less than one dollar, opening the door for possible commercialization. One company, Bell Industries, has started to market the devices as a pilot.

Raising farmers and policymakers’ awareness on appropriate storage and drying technologies is now a priority for scientists working on the FPL project, which will hopefully lead to less maize spoiled and better food safety.

International research-for-development coalition against fall armyworm, the not-so-nice, very hungry caterpillar

ADDIS ABABA, Ethiopia (CIMMYT) — African farmers have lost millions of dollars in earnings since 2016 due to the loss of crops to the voracious fall armyworm.

Since the initial shock, farmers, researchers, extension officers, agribusinesses, governments and donors have reacted quickly to fight the invasive pest in various ways, including with pesticides, agroecological approaches and new seeds.

Yet the situation is far from under control. A more coordinated research-for-development (R4D) action plan is urgently needed to ensure that effective and affordable solutions reach smallholder farmers in sub-Saharan Africa so they can sustainably combat the devastating pest.

Smallholder farm socioeconomics are highly complex, which makes adoption of any new technology or practice a challenge. “We must look at the big picture to design safer, accessible, effective and sustainable solutions against fall armyworm,” said Martin Kropff, director general of the International Maize and Wheat Improvement Center (CIMMYT), which jointly coordinated “Fall Armyworm Research for Development: Status and priorities for Africa,” an international conference held from Oct. 29 to 31 at the African Union Commission in Addis Ababa, Ethiopia.

Hosted by the Fall Armyworm R4D International Consortium, the conference was aimed at drawing a science-based roadmap to combat the hungry caterpillar. The partners organizing the conference were the African Union Commission (AUC), the Alliance for a Green Revolution in Africa (AGRA), the Centre for Agriculture and Biosciences International (CABI), CIMMYT, the Food and Agriculture Organization of the United Nations (FAO), the International Centre of Insect Physiology and Ecology (icipe), the International Institute of Tropical Agriculture (IITA), and the United States Agency for International Development (USAID).

Vulnerable smallholder farmers

African leaders consider the invasive fall armyworm “a big threat for African food security,” said Amira Elfadil, African Union Commissioner for Social Affairs, at the opening of the conference.

The caterpillar has munched through thousands of hectares of maize, sorghum and a few other commercial crops across Africa and is causing severe concerns among food and agriculture experts and policymakers. Since it was first detected in Nigeria and São Tomé, the moth has spread across more than 40 African countries and has been seen in India since July 2018. It could also invade Europe and other continents.

“Fall armyworm has been the fastest pest to expand across the continent,” said Eyasu Abraha, Ethiopia’s state minister for agriculture development.

The pest is a familiar foe to agricultural experts and farmers in the Americas who have fought against it for several decades. However, the pest has found an ideal environment to flourish in Africa, with diverse agro-ecologies and a warmer climate all year round amplifying its persistent threat.

It has a host range of more than 80 plant species, including maize, a staple food on which millions of people throughout sub-Saharan Africa depend for food and income security. It can cause total crop losses, and at advanced larval development stages can be difficult to control even with synthetic pesticides. The female fall armyworm can lay up to a thousand eggs at a time and produce multiple generations very quickly without pause in tropical environments. The moth can fly 100 km (62 miles) a night, and some moth populations have even been reported to fly distances of up to 1,600 kilometers in 30 hours, according to experts.

Entomologists are trying to fill a knowledge gap on how the fall armyworm behaves and migrates throughout Africa.

Solutions that may work to combat the pest in Brazil or North America may not be applicable for the agricultural context in Africa where most farmers are low-resource smallholders, struggling to access new knowledge and technologies.

High cost of ineffective collaboration

Hans Dreyer, director of FAO’s plant protection division, listed many collaborative initiatives, including national task forces and expert working groups, which contributed to document and inform the current state of knowledge.

There are still many knowledge and technical gaps. Some resourceful information platforms are already available for the farmers and extension workers, including the fall armyworm web portal created by CABI, the mobile farmer Q&A service PlantVillage, or Precision Agriculture for Development’s text messaging advisory service MoA-Info.

“The cost of not collaborating is pretty severe,” said Regina Eddy, who leads the Fall Armyworm Task Force at the USAID Bureau for Food Security. The real gamechanger will be that “all experts in the room agree on a common and concrete research-for-development agenda and how to organize ourselves to implement it effectively,” she added.

During the conference, the experts debated intensely on the technical gaps and the best ways to combat the pest through an integrated pest management strategy, including how to scout the caterpillar in the crop field, establish monitoring and surveillance systems, pest control innovations and appropriate policy support to accelerate introduction of relevant innovations.

Safe, sustainable, farmer-centered solutions

Short-term responses to the pest at present include synthetic pesticide use. However, there are public health and environment concerns over some of the toxic pesticides being used in Africa to control the fall armyworm.

Brian Sobel from Catholic Relief Services recalled witnessing a woman in Malawi who, in an effort to combat the pest, sprayed much more chemical pesticide on her maize than necessary.

The rapid increase of the pesticide market in Africa has led to the circulation of plenty of banned or counterfeit products, some very toxic for the farmer, said Steven Haggblade, a professor in the Department of Agricultural, Food and Resource Economics at Michigan State University in the United States. Farmers are often not well trained in the use of such chemicals and do not protect themselves during application, he said.

Pesticide use has many negative trade-offs, said Paul Jepson, a professor of environmental and molecular toxicology in the College of Agricultural Sciences at Oregon State University. Natural enemies like parasitic wasps are also often far more vulnerable to pesticides than fall armyworm larvae, which are hard to reach and hide themselves in the maize whorls for instance.

Continental action plan

A key recommendation made by the Fall Armyworm R4D International Consortium is to develop common methodologies and research protocols to ensure data from various studies across the continent are better used and compared. For example, how best could the true impacts of the fall armyworm on food and seed security, public health and environment be measured? Collaborative research could include multilocation assessment of the relationship between observed crop damages and yield losses, which is key to determine the efficacy of a pest control innovation.

Conference participants also agreed to work on defining economic and action thresholds for fall armyworm interventions, to ensure better recommendations to the farming communities.

Because no one solution can fit all farmers and socioeconomic contexts, advice must include use of environmentally safer pesticides, low-cost agronomic practices and landscape management and fall armyworm-resistant varieties, among other integrated pest management tools.

Enhanced cooperation between countries to access new technologies and manage the transboundary pest is seen as a priority. Consortium experts also urge an integrated pest management approach, initiated based on farmers’ needs. Controlling the fall armyworm in the long run will require important investments into research-for-development for generating and sharing knowledge and addressing technical gaps with farmers.

Climate change could mean beer shortages on tap

EL BATAN, Mexico (CIMMYT) — As the impact of climate change on food staples becomes more apparent, scientists with the International Maize and Wheat Improvement Center (CIMMYT) are beginning to study how increasing temperatures will affect other contributors to the human diet. A new study indicates that the global beer supply will be hard hit. Given how seemingly plentiful beer is, this is difficult news to hear.

The study,Decreases in global beer supply due to extreme drought and heat,” was simplyborn out of a love for beer and the fear of its potential scarcity,” says Wei Xiong, a senior scientist at the CIMMYT and a key contributor to the research.

Two years ago, Xiong and the other scientists began to design the study to learn more about extreme drought and heat patterns adversely affecting crops around the world. Barley, the primary cereal grain from which beer is brewed, is one of the most heat-sensitive crops, meaning that even short periods of high temperatures can affect grain quality and grain yield.

Despite a number of studies published assessing yield loss of barley and other crops due to global warming, there were no previous studies published connecting the price of beer to barley yield. The study, which the scientists refer to as the “drinking security” project, has garnered world-wide interest from various media outlets given the popularity of beer.

Wanting to connect their research with an interest of the general public, or the price of beer, the study’s authors saw value in researching the intersection of barley, beer and climate change. As a cross-culturally shared beverage, beer — to some extent — is more popular than rice, wheat and maize as it is recognized as a lifestyle staple. “This is the reason why we chose barley and beer as the case crop, to raise awareness of climate change and its impacts. The wide interest in the study proved we succeed,” says Xiong.

The study also points out an alternative way to raise the public awareness of climate change for the future, or presenting an issue that has tangible realities for the average person. “Consuming less beer thanks to climate change won’t necessarily affect global health, but having no beer will definitely add insult to injury, particularly when we’re watching sports matches,” says Xiong. “If you still want a few pints of beer, then the only way to do so is to mitigate climate change.”

In the process of conducting climate and crop model simulations for the study, Xiong improved available data on global barley supply through the introduction of the Decision Support System for Agrotechnology Transfer (DSSAT), a program used for simulating crop growth, to develop a global calibration algorithm to allow the model to reproduce historical and projected future barley production.

This was the first endeavor to date using the DSSAT model for single crop analysis on a global scale — a total of 38 barley producing regions were analyzed. Xiong also assisted in the designing of the study’s extreme warm weather index to identify extreme drought and heat years from climate simulation outputs.

Following the use of DSSAT, CIMMYT-led High Performance Computing (HPC) allowed for the calculation of barely grain yield change due to extreme drought and heat, a fundamental component of the study. CIMMYT is currently establishing the modeling capacity to be able to cover 30 more crops worldwide in addition to barley with multiple HPC models. This will ultimately aid CIMMYT in analyzing agricultural and economic risks associated with maize and wheat.

The study acknowledges its limitations as a result of factors that were kept constant such as the behaviors of barley producers and beer drinkers, global food stock and population growth. “One shortcoming of the paper that could be improved in cooperation with CIMMYT is looking at the spatial shift of crop area under a warming climate,” Xiong says. “This area shift, or cultivar shift between regions, has already happened in many countries to help cope with a warming climate, but we are not clear how it happens and its resulting consequences.”

Despite the study’s findings, there is still space to develop the analysis by further considering the implications of future climate change forecasts. While the fate of beer seems bleak, there is still hope for the beverage in that the study did not consider the world’s progress in developing heat and drought resistant barley varieties and their adoption by farmers. However, Xiong particularly believes that the study signals the butterfly effect in climate change impacts, meaning that everyone will eventually suffer from the effects of climate change if no action is taken to fight it.

With news of a potential decrease in the world’s beer supply, climate change seems to have abruptly arrived on beer lovers’ doorsteps.
