Location: Asia

As a fast growing region with increasing challenges for smallholder farmers, Asia is a key target region for CIMMYT. CIMMYT’s work stretches from Central Asia to southern China and incorporates system-wide approaches to improve wheat and maize productivity and deliver quality seed to areas with high rates of child malnutrition. Activities involve national and regional local organizations to facilitate greater adoption of new technologies by farmers and benefit from close partnerships with farmer associations and agricultural extension agents.

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.

Hosneara Bibi is a farmer in the village of West Ghughumari, in the Cooch Behar district of West Bengal, India. She began her journey as an agricultural entrepreneur two years ago, when members of the nonprofit Satmile Satish Club o Pathagar (SSCOP), a CIMMYT partner, first came to her village.

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

In the context of the SRFSI project and in collaboration with Godrej Agrovet, Bibi and her self-help group received training on conservation agriculture practices for sustainable intensification. Self-help groups are small associations, usually of women, that work together to overcome common obstacles. With support from SSCOP, Bibi’s fellow group members learned about a variety of improved agricultural practices, including zero tillage, which improves soil nutrient levels and water efficiency. This support helped them to increase their crop yields while promoting sustainability.

After adopting the improved practices, Bibi increased her wheat yield by 50 percent. This positive experience encouraged her to implement mechanically transplanted rice technology. Bibi and her self-help group have since started a rice seedling enterprise and they offer their mechanically transplanted rice services to other farmers. This has become a profitable agri-enterprise for the group.

Bibi has been able to expand her farm and now cultivates wheat, rice and jute. She has also adopted digital technologies in her farming practice and now uses a mobile app to aid in pest management for her rice crop, designed by Uttar Banga Krishi Viswavidyalaya.

Because of her higher yields and the profitability of the self-help group’s rice seedling enterprise, Bibi has successfully increased and diversified her income. Her proudest moment was when she was able to buy a motorbike for her husband.

Members of the SRFSI team consider Hosneara Bibi a role model for other farmers and entrepreneurs in her community.

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

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).

New study: India could cut nearly 18% of agricultural greenhouse gas emissions through cost-saving farming practices

NEW DELHI (CIMMYT) — India could reduce its greenhouse gas emissions from agriculture by almost 18 percent through the adoption of mitigation measures, according to a new study. Three improved farming practices would account for more than half of these emission reductions, researchers say: efficient use of fertilizer, zero tillage and better water management in rice farming.

In an article published in Science in the Total Environment, scientists estimate that, by 2030, “business-as-usual” greenhouse gas emissions from the agricultural sector in India would be 515 MtCO2e per year. The study indicates that Indian agriculture has the potential to mitigate 85.5 Megatonne CO2 equivalent (MtCO2e) per year without compromising food production and nutrition. Considering the 2012 estimates of 481 MtCO2e, that would represent a reduction of almost 18 percent. Researchers suggest mitigation options that are technically feasible but will require government efforts to be implemented at scale.

The study was conducted by scientists from the International Maize and Wheat Improvement Center (CIMMYT), the University of Aberdeen and the Indian Council of Agricultural Research (ICAR), with support from the CGIAR Research Program on Climate Change, Agriculture, and Food Security (CCAFS). They followed a “bottom-up” approach to estimate and analyze greenhouse gas emissions from agriculture, using large datasets related to crops (around 45,000 data points) and livestock production (around 1,600 data points) along with soil, climate and management information. To evaluate mitigation measures, associated costs and benefits of adoption, researchers used a variety of sources, including literature, stakeholder meetings and consultations with experts in crops, livestock and natural resource management.

The authors also identify “hotspots” where mitigation practices would have the highest potential for reduction of greenhouse gas emissions. For example, reduced fertilizer consumption through precision nutrient management shows the highest potential in the state of Uttar Pradesh, followed by Andhra Pradesh, Maharashtra and Punjab. Water management in rice farming has the highest mitigation potential in Andhra Pradesh, followed by Tamil Nadu, Orissa and West Bengal.

India is the world’s third largest emitter of greenhouse gases. Contributing almost one-fifth to the national total, agriculture has been identified as a priority in the country’s efforts to reduce emissions. The results from this study can help the country make great strides towards its goals. However, these climate change mitigation benefits can only work if farmers take up the new practices, some of which require an initial investment. Government policies and incentives will be crucial to help farmers take the first steps, ensure wide-scale adoption of these mitigation options, and help India meet its food security and greenhouse gas emission reduction goals.

Three feasible mitigation measures

Efficient use of fertilizer not only lowers emissions at the field, but also reduces the need for fertilizer and the emissions associated with production and transportation. It also represents savings for the farmer. Mitigation options would include applying fertilizer at the right time and the right place for plant uptake, or using slow-release fertilizer forms or nitrification inhibitors. “Efficient fertilizer use in the agriculture sector in India has potential to reduce around 17.5 MtCO2e per year,” said Tek Sapkota, CIMMYT scientist and lead author of the study.

Adoption of zero tillage farming and residue management — maintaining crop residues on the soil surface to protect the ground from erosion — in rice, wheat, maize, cotton and sugarcane was shown to reduce emissions by about 17 MtCO2e per year. “CIMMYT has successfully worked to develop and promote these practices in India,” said M.L. Jat, CIMMYT principal scientist and co-author of the study.

Better water management in rice farming — such as adopting alternate wetting and drying in rice fields that are currently continuously flooded — can offer mitigation of about 12 MtCo2e per year. Other water management techniques in major cereals, such as laser-levelling of fields, or using sprinkler or micro-sprinkler irrigation and fertigation together, also provide important greenhouse gas emissions savings, with a reduction of around 4 MtCO2e per year for laser levelling alone.

This work was jointly carried out by the International Maize and Wheat Improvement Center (CIMMYT) and the University of Aberdeen. Research was funded by the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS), supported by CGIAR Fund Donors and through bilateral funding agreements.

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).

New publications: Does a climate-smart village approach influence gender equality in farming households?

South Asia faces multiple food security challenges, one of which being its extreme vulnerability to climate change. Millions living in the region are expected to be affected by water stress, yield loss, and other climate disasters caused by rising temperatures. Technological innovations can in important tool in ensuring food and livelihood security in the region, but social inclusivity is key to promoting the large-scale adoption of new technologies and practices.

Women’s participation in agricultural activities is increasing over time, but many still have limited capacity to contribute to farm decision-making. They may also have limited control over and access to resources such as credit, extension services and markets. The CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS) has developed and piloted the use of climate-smart villages (CSVs) in the Indian states of Bihar and Haryana to test climate-smart agriculture options for managing climate-related risks and promoting gender equality in agricultural production.

As climate change disproportionately affects poor and socially marginalized groups, including women, it is important to understand the ways in which the climate-smart approach helps to address specific climate change adaptation challenges. However, there are few studies to date focusing on this question.

In an attempt to fill this gap, a new study carried out as part of the CCAFS project on Climate-Smart Agriculture analyzes the extent to which the climate-smart village approach can contribute to establishing greater gender equality across the agricultural, political, social and economic sectors. The study introduces a Gender Empowerment Index for climate-smart villages, based on measurable indicators. It also documents the gender gap by mapping differences in empowerment levels across selected climate-smart villages and other villages across India’s eastern and western Indo-Gangetic Plains.

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.

Jason Donovan joined CIMMYT in 2017 and leads CIMMYT’s research team on markets and value chains, based in Mexico. He has some 15 years of experience working and living in Latin America. Prior to joining CIMMYT he worked at the Peru office of the World Agroforestry Center (ICRAF), where his research focused on business development, rural livelihoods, gender equity and certification. He has a PhD in development economics from the University of London’s School of Oriental and African Studies (SOAS).

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.

Inspiring millennials to focus on food security: The power of mentorship

As part of their education, students worldwide learn about the formidable challenges their generation faces, including food shortages, climate change, and degrading soil health. Mentors and educators can either overwhelm them with reality or motivate them by real stories and showing them that they have a role to play. Every year the World Food Prize lives out the latter by introducing high school students to global food issues at the annual Borlaug Dialogue, giving them an opportunity to interact with “change agents” who address food security issues. The World Food Prize offers some students an opportunity to intern at an international research center through the Borlaug-Ruan International Internship program.

Tessa Mahmoudi

Plant Microbiologist Tessa Mahmoudi, a 2012 World Food Prize’s Borlaug-Ruan summer intern, says her experience working with CIMMYT researchers in Turkey when she was 16 years old profoundly changed her career and her life.

“For a summer I was welcomed to Turkey not as a child, but as a scientist,” says Mahmoudi, who grew up on a farm in southeast Minnesota, USA. “My hosts, Dr. Abdelfattah A. Dababat and Dr. Gül Erginbas-Orakci, who study soil-borne pathogens and the impact those organisms have on food supplies, showed me their challenges and, most importantly, their dedication.”

Mahmoudi explains she still finds the statistics regarding the global food insecurity to be daunting but saw CIMMYT researchers making real progress. “This helped me realize that I had a role to play and an opportunity to make positive impact.”

Among other things, Mahmoudi learned what it meant to be a plant pathologist and the value of that work. “I began to ask scientific questions that mattered,” she says. “And I went back home motivated to study — not just to get good grades, but to solve real problems.”

She says her outlook on the world dramatically broadened. “I realized we all live in unique realities, sheltered by climatic conditions that strongly influence our world views.”

According to Mahmoudi, her internship at CIMMYT empowered her to get out of her comfort zone and get involved in food security issues. She joined the “hunger fighters” at the University of Minnesota while pursuing a bachelor’s in Plant Science. “I was the president of the Project Food Security Club which focuses on bring awareness of global hunger issues and encouraging involvement in solutions.” She also did research on stem rust under Matthew Rouse, winner of the World Food Prize 2018  Norman Borlaug Award for Field Research and Application.

Pursuing a master’s in plant pathology at Texas A&M University under the supervision of Betsy Pierson, she studied the effects of plant-microbe interactions on drought tolerance and, specifically, how plant-microbe symbiosis influences root architecture and wheat’s ability to recover after suffering water stress.

Currently, Mahmoudi is involved in international development and teaching. As a horticulture lecturer at Blinn College in Texas, she engages students in the innovative use of plants to improve food security and global health.

Mahmoudi incorporates interactive learning activities in her class (see her website, https://reachingroots.org/). Her vision is to increase access to plant science education and encourage innovation in agriculture.

“As a teacher and mentor, I am committed to helping students broaden their exposure to real problems because I know how much that influenced me,” Mahmoudi says. “Our world has many challenges, but great teams and projects are making progress, such as the work by CIMMYT teams around the world. We all have a role to play and an idea that we can make a reality to improve global health.”

As an example, Mahmoudi is working with the non-profit Clean Challenge on a project to improve the waste system in Haiti. The initiative links with local teams in Haiti to develop a holistic system for handling trash, including composting organic waste to empower small holder farmers to improve their soil health and food security.

“Without my mentors, I would not have had the opportunity to be involved in these high impact initiatives. Wherever you are in your career make sure you are being mentored and also mentoring. I highly encourage students to find mentors and get involved in today’s greatest challenge, increasing food security.”

In addition to thanking the CIMMYT scientists who inspired her, Mahmoudi is deeply grateful for those who made her summer internship possible. “This would include the World Food Prize Foundation and especially Lisa Fleming, Ambassador Kenneth M. Quinn, the Ruan Family,” she says. “Your commitment to this high-impact, experiential learning opportunity has had lasting impact on my life.”

CIMMYT set to strengthen collaboration with China’s Sichuan Province

On October 23, 2018, the International Maize and Wheat Improvement Center (CIMMYT) welcomed a delegation of government officials from Sichuan Province, China, for the signing of a memorandum of understanding.

The Vice Governor of the Sichuan Province Government, Yao Sidan, led the delegation, which included representatives from the provincial government, the Sichuan Forestry Department, Chongzhou Municipal Government, and the Sichuan Academy of Agricultural Sciences (SAAS).

They met with CIMMYT’s Deputy Director General, Marianne Bänziger; the Director of the Global Wheat Program, Hans Braun; the Director of the Sustainable Intensification Program, Bruno Gerard; and the Head of Bread Wheat Improvement and Rust Research, Ravi Singh.

CIMMYT representatives presented the center’s current research agenda in China and discussed with Sichuan officials possible opportunities for strengthening collaboration.

Sichuan is the fourth most populated province in China, with a population of 91 million, over two-thirds of whom live in rural areas. The province is rich in natural resources and has a cultivated land area of 10 million hectares. Despite its rapid development over the past decades, 1.7 million of Sichuan’s inhabitants still live in poverty and food security remains a key priority. In order to improve standards of living, it is important to ensure that Sichuan residents not only have enough food, but that they can harvest and consume high-quality crops.

Looking into the future of a long partnership

“CIMMYT’s support and collaboration is very important for us,” explained Yao. Collaboration between CIMMYT and the Sichuan Academy of Agricultural Sciences has contributed to a significant improvement in standards of living within the province over the last 30 years, but there is scope for deepening and widening the partnership in order to continue improving maize and wheat production in the region.

Maize and wheat research is particularly advanced at the Sichuan Academy of Agricultural Sciences. Many of its scientists are already working closely with CIMMYT researchers, but further collaboration is required to tackle ongoing wheat production and quality challenges.

“CIMMYT has enjoyed many years of collaboration with scientists in Chengdu,” said Singh, “and though there has been successful development of wheat varieties using CIMMYT germplasm, production and quality is still being affected by challenges such as yellow rust and rising water levels of the Yellow and Yangtze rivers.” However, he explained, CIMMYT can offer wheat materials for greater quality.

Gerard highlighted that as one of the world leaders in terms of conservation agriculture, China can play a key role in reducing global agriculture’s environmental footprint. CIMMYT also stands to learn from China’s expertise on agricultural technologies, he added, particularly with regard to precision agriculture, small-scale mechanization, and other tools that would prove useful to farmers in other regions of the world.

Another possible area for collaboration is researching the effects of radiation on yield loss and crop quality. There is evidence that wheat yields in other countries are significantly reduced by high levels of pollution, but the full effects of radiation on yield loss are still not very well understood, particularly in China. There is also scope to strengthen cooperation on seed industries, the use of specialty maize, diversification and aflatoxins.

Rooting for a green comeback

For decades, rice stubble has been burned in India to clear fields and prepare for wheat sowing. The easiest way of getting rid of rice crop residue is to burn it in bulk, but this poses a serious threat to the entire biosystem, from soil nutrition to human health. Deteriorating soil health results in lower crop yields, increased dependence on fertilizers, and increased water volume requirements for irrigation, all of which have negative impacts on farmer incomes.

“Earlier when rice harvesting was manual, crop residues were taken out from fields and farmers benefited from selling them,” explains M.L. Jat, principal scientist and systems agronomist at CIMMYT. “Later, when agriculture included more mechanical operations for harvesting with the increase in the production to the tune of millions of tons, crop residue became a hazard in terms of disposal that would involve huge money, labor, and logistics.”

Wheat breeding must account for warmer, wetter climates in North America and Russia, new study shows

FOR IMMEDIATE RELEASE           

MEXICO CITY — Breeders of spring wheat for North America and Russia need to adapt their varieties to the regions’ changing climates, which are bringing longer and wetter whegrowing seasons, according to a scientific paper published yesterday.

Published by a five-country team of wheat researchers, the study analyzed changes in wheat yields, along with air temperatures and precipitation, on farms and research stations in Canada, Kazakhstan, Russia, and the USA, from 1981 to 2015.

The 22 million hectare study area — nearly the size of the United Kingdom — accounts for as much as 10 percent of global wheat production and exports nearly all its wheat, making it a big contributor to world food markets, according to Alexey Morgounov, wheat scientist at the International Maize and Wheat Improvement Center (CIMMYT) and first author of the paper.

“June, when the grain-holding wheat spike begins to form, turned out to be the critical month for spring wheat,” Morgounov said. “Maximum temperatures for that month rose over the 35 years studied, which hurt yields, but average rainfall increased and boosted grain yield, offsetting the temperature effect.”

Still, breeding for adaptation to higher temperatures will be critical to increasing spring wheat yields, according to Morgounov, who added that there were substantial changes in the dates of planting and harvesting, normally leading to longer growing seasons in the regions studied. “New varieties should be able to take advantage of the longer wheat growing seasons that warming brings.”

Overall, climate changes were more favorable for spring wheat in North America than in Kazakhstan and Russia, with greater precipitation in Canada and the USA and less exposure to extreme, high temperatures. Growing season precipitation increased as much as 15 percent at North American locations.

The two regions covered in this study represent distinct environments. The Kazakhstan and Russia locations are more than 500 kilometers further north than the North American latitudes and experience colder winters, hotter summers, and less precipitation.

“Interestingly, the two regions appear to complement each other, over the period we studied,” Morgounov said. “Higher-than-average wheat yields in one were normally associated with lower yields in the other, helping to foster stability in grain markets.”

“The whole high-latitude, continental climate spring wheat area certainly presents a huge potential for global wheat production,” he added, “and both can benefit from germplasm exchange and cooperation, with emphasis on the climate change challenges and opportunities presented in this paper.”

Morgounov acknowledged contributions for the study from the Prairie Recommending Committee on Wheat, Rye and Triticale, Canada, and other Canadian partners; the USDA-ARS Plant Science Research Unit; the Samara Agricultural Research Institute, the Agricultural Research Institute of Southeast Saratov, the Altay Agricultural Research Institute at Barnaul, the Siberian Agricultural Research Institute at Omsk, the Shortandy Variety Testing Site, and the Siberian Crop  Production Research Institute at Novosibirsk, Russia; and the Karabalyk Agricultural Research Station, Kostanay, Kazakhstan. Finally, Morgounov thanked the CGIAR Research Program on Wheat for its support.

Scaling up mechanization in Bangladesh through partnerships

Over the last two decades, a significant number of rural Bangladeshis – especially youth – have migrated to urban centers, looking for higher paying jobs and an escape from agricultural labor. Reaper-DemoConor Riggs is the Global Director of Markets and Entrepreneurship at iDE. He says smallholder farmers in Southern Bangladesh are increasingly struggling to find and afford farm labor to help harvest crops and perform a variety of other on-farm activities.

Riggs says small-scale mechanization, such as two-wheeled tractors fitted with intensification machinery and surface irrigation pumps, can help farmers make up for this labor gap and increase productivity, while boosting the local economy by supporting micro- and small enterprises.

But as Riggs discussed at the recent Scale Up Conference at Purdue University, designing the perfect machine or technology is not enough to create sustainable, far-reaching impact. On the International Day for the Eradication of Poverty, we’re following up with him to learn more about the role of markets and partnerships in bringing small-scale mechanization to rural Bangladesh.

Q: Five years ago, CIMMYT and iDE co-designed and began implementing the USAID Cereal Systems Initiative for South Asia – Mechanization and Irrigation (CSISA-MI) project. What were the goals when you began?

Our goal was to establish a new industry for attachments in two-wheel tractors in agricultural mechanization, technologies like seeders, reapers and high-volume irrigation pumps for surface water. We wanted to help farmers access services through a fee-for-service model – small entrepreneurs buy machines and rent out those machines to farmers or directly provide that service themselves. There wasn’t really a market naturally growing for these machines in ways that included smallholders while being commercially viable, so we aimed to build it as best we could.

The results of this effort to date have been strong: 191,000 farmers can now access machinery services from a growing network of nearly 3,000 local microenterprise service providers, representing improved cultivation across 92,000 hectares in Southern Bangladesh. And we see abundant evidence that this market is scaling organically now that it’s established a model that works for both firms and farms.

Q: How did you create a market?

We incentivized several large conglomerates in the agri-business space to co-invest with us on several container-loads of these machines, which we imported from Thailand and China. We helped them find some early adopter dealers and local service providers who would actually buy them. Then we developed short-term smart subsidies to drive down the costs of supply chain development, accelerated customer adoption of the machines, and overall market growth.

An important aspect of our strategy is that we did not present these accelerating investments as typical subsidies; rather, we worked with our private partners to offer commercial discounts so that service providers and farmers Md Lalchan Shardar is a farmer and local service provider. The axial flow pump cuts the amount of irrigation time in halfwould recognize the true value of the product and the short-term opportunity to adopt the technology in its initial commercialization phase.

We first implemented this strategy with two leading firms in the market who concurrently launched a very proactive marketing campaign. Then we started pulling back those discounts overtime, year by year, as the initial partner firms found the market opportunity, and redirected this acceleration process with an additional group of interested companies that also wanted to enter the market in an inclusive manner.

Q: So the companies were benefiting from the discount?

Yes, but we created a lot of conditions. Essentially, the more project investment that was committed by the project to discount the cost of the machinery, the more we expected to see both cash and in-kind investment from those companies. In the end, about a dozen companies come into the game with about five that have really driven a lot of heavy investment.

Partnerships have been key throughout this project. What were the different strengths iDE and CIMMYT brought to the table?

iDE is a market development organization. We focus on market-based solutions, technology commercialization, last mile distribution, and market access. Fundamentally, we see our job as de-risking the market for companies to invest in lower income areas and empower the farmer and their family as both consumers and suppliers in the formal economy. To do this, we employ a lot of supply chain development, product re-design and most importantly, we develop networks of micro-entrepreneurs to serve the ‘missing middle’ between the formal and informal economies.

CIMMYT brings leading capabilities in linking science and practice, with an un-paralleled strength in understanding the agronomic rationale and the agronomic and economic combinations of the technologies as they’re applied on the ground.

CIMMYT knew what technologies were needed on the ground in Southern Bangladesh to genuinely improve productivity and efficiency in the face of changing economic circumstances, and understood how to apply them to real world conditions in alignment with market-based diffusion mechanisms. CIMMYT was also instrumental in working closely with the Bangladesh Agriculture Research Institute (BARI) and extension services, key government partners that helped us ensure market development was in alignment with public and social policy.

It can be difficult finding a synergy between two different organizations. Did you run into any challenges?  

CIMMYT and iDE have different specializations, and at the beginning, we had natural, friendly debates about how to best integrate them and achieve highly ambitious project objectives. But relatively quickly, we figured out how to learn from each other and synthesize our approaches for the best results. Both CIMMYT and iDE approached the partnership with a mission driven focus and a sense of constant, mutual respect for the value each partner brought to the table.

What do you see for the future? 

As for iDE, we’re excited to expand this successful partnership with CIMMYT to figure out how we can further replicate this success in other countries where we both work. While some of the market conditions in Bangladesh have provided us with unique opportunities for technology scaling in mechanization, we’re highly optimistic that the underlying partnership principles and management systems of CSISA-MI can be replicated in other programs and country contexts – even in ostensibly more challenging market environments.

The CSISA-MI project is funded by USAID.
