Visiting researcher Fazleen Abdul Fatah is studying the growing importance of maize and wheat in emerging economies.
Fazleen Abdul Fatah credits a number of factors for her interest in agricultural research, from a childhood spent in a small town in one of Malaysia’s main rice farming areas, where the neighborhood revolved around agriculture, to supporting lecturers and professors who encouraged her interests during her undergraduate studies. “My experiences as an intern in the Philippines and visiting commercial farms in Germany and Japan as a student also shaped my motivation to work in sustainable agriculture and rural development, and ultimately I’d like to be able to influence food and agriculture policy,” she says.
Now a senior lecturer in the Faculty of Plantation and Agrotechnology at Universiti Teknologi MARA (UITM) in Malaysia, where she specializes in agricultural economics, trade and policy. For the past three months she has been based at the global headquarters of the International Maize and Wheat Improvement Center (CIMMYT) in Mexico, where she is conducting research into food consumption patterns.
Having previously completed an internship with the International Rice Research Institute (IRRI) in the Philippines, Abdul Fatah was keen to gain more experience within the CGIAR system. After graduating from the University of Gottingen, Germany, with a PhD in Agriculture Trade Policy, her interest in the growing importance of maize and wheat in emerging economies prompted her to apply for a research opportunity at CIMMYT.
“I’m very interested in understanding how current shifts in food consumption patterns might affect the consumption of cereals in Indonesia and Malaysia.” Her previous research focused on the shift to cereals from food items such as meat, fish, or vegetables, but Abdul Fatah notes that few studies document shifts between cereals. “Rice is typically the main staple food crop for Malaysians,” she explains, “but changes in diets, incomes, and urbanization mean that people are shifting towards maize and wheat. What I’ve found more striking from my research is that in some areas people are actually consuming more wheat than rice, which means there are going to be some interesting decisions for policy makers to consider in the near future, especially in terms of import strategies.”
Abdul Fatah presented her initial research findings at CIMMYT, where she updated colleagues on her efforts to analyze consumption patterns for major cereals in 11 developing countries in Africa and Asia using government household surveys and World Bank datasets. She hopes to continue this line of research once she returns to UITM and is currently working on a paper based on case studies from Indonesia and Malaysia.

NEW DELHI (CIMMYT) — Imbalanced application of different plant nutrients through fertilizers is a widespread problem in India. The major reasons are lack of adequate knowledge among farmers about the nutritional requirement of crops, poor access to proper guidelines on the right use of plant nutrients, inadequate policy support through government regulations, and distorted and poorly targeted subsidies.
This context makes it necessary to foster innovation in the fertilizer industry, and also to find innovative ways to target farmers, provide extension services and communicate messages.
A dialogue on “Innovations for promoting balanced application of macro and micro nutrient fertilizers in Indian agriculture” facilitated discussion on this issue. Representatives from key fertilizer industries, state governments, research institutions and the Indian Council of Agricultural Research gathered in New Delhi, India, on December 12, 2018. This dialogue was part of the Cereal Systems Initiative for South Asia (CSISA) and was organized by the International Food Policy Research Institute (IFPRI) and the International Plant Nutrition Institute (IPNI).

The Director General of the Fertilizer Association of India (FAI), Shri Satish Chander, pointed out that new-product approvals in India take approximately 800 days. However, he explained, this delay is not the biggest problem facing the sector: other barriers include existing price controls that are highly contingent on political myths.
IFPRI researcher Avinash Kishore presented evidence contradicting the myth that farmers are highly sensitive to any price change. He presented data demonstrating that farmers’ demand for Urea and DAP remained highly price inelastic during periods of steep price increases, in 2011 and 2012.

The Director of the South Asia Program at IPNI, T. Satyanarayana, highlighted the importance of micronutrients in promoting balanced fertilization of soils and innovative methods for determining soil health.
Andrew McDonald, from the International Maize and Wheat Improvement Center (CIMMYT), presented the new Soil Intelligence System for India, which employs innovative approaches to soil health assessments.
Farmers’ representative Ajay Vir Jakhar elaborated on the failure of underfunded extension systems to reach and disseminate relevant, factual and timely messages to vast numbers of farmers.
Other representatives from the fertilizer industry touched upon the need to identify farmer requirements for risk mitigation, labor shortages and site-specific nutrient management needs for custom fertilizer blends. Participants also discussed field evidence related to India’s soil health card scheme. Ultimately, discussions held at the roundtable helped identify relevant policy gaps, which will be summarized into a policy brief.

In 2018, our editors continued to cover exciting news and events related to maize and wheat science around the world. Altogether, we published more than 200 stories.
It is impossible to capture all of the places and topics we reported on, but here are some highlights and our favorite stories of the year.
Thank you for being a loyal reader of CIMMYT’s news and features. We are already working on new stories and platforms for 2019. Stay tuned!
In response to the spread of the fall armyworm across Africa, CIMMYT and its partners published a technical guide for integrated pest management. Produced by international experts, it offers details on the best management practices to help smallholder farmers effectively and safely control the pest while simultaneously protecting people, animals and the environment.
This year we launched our new podcast, Cobs & Spikes, where you can listen to stories from the field, interviews and explainers.
The most popular episode so far was about blue maize, a distinctive feature of Mexico’s food culture. Valued for its rich flavor and texture, it is also catching the attention of some food processing companies and high-end culinary markets. CIMMYT researchers are helping Mexican farmers tap into two emerging markets that could boost incomes while conserving culture and biodiversity.
A review of scientific studies on cereal grains and health showed that gluten- or wheat-free diets are not inherently healthier for the general populace and may actually put individuals at risk of dietary deficiencies.
Based on a compilation of 12 reports, eating whole grains is actually beneficial for brain health and associated with reduced risk of diverse types of cancer, coronary disease, diabetes, hypertension, obesity and overall mortality.
Mechanized agricultural services have traditionally only been used by large-scale farmers who could afford them, but small and medium-sized machines are fast becoming affordable options for family farmers through the advent of service providers. An increasing number of young people across eastern and southern Africa are creating a stable living as entrepreneurs, providing agricultural mechanization services.
CIMMYT is offering training courses to promote mechanization in Ethiopia, Kenya, Tanzania and Zimbabwe. Trainings equip entrepreneurs with essential business skills and knowledge, tailored to rural environments, so they can support farmers with appropriate mechanization services that sustainably intensify their production.

In a scientific breakthrough, the International Wheat Genome Sequencing Consortium presented an annotated reference genome with a detailed analysis of gene content among subgenomes and the structural organization for all the chromosomes. The research was published on Science.
Over 46 percent of children under five in Guatemala suffer from chronic malnutrition. More than 40 percent of Guatemala’s rural population is deficient in zinc, an essential micronutrient that plays a crucial role in pre-natal and post-natal development and is key to maintaining a healthy immune system.
CIMMYT is working with partners HarvestPlus and Semilla Nueva to reduce malnutrition and zinc deficiency in the country, through the development and deployment of Guatemala’s first biofortified zinc-enriched maize.
CIMMYT was present at the African Green Revolution Forum in Kigali, Rwanda. Leaders discussed practical ways to transform policy declarations into impact on the ground, at a time when farmers are facing the challenge of climate change and the threat of emerging pests and diseases.
On the occasion of this event, CIMMYT’s Director General, Martin Kropff, and the Regional Representative for Africa, Stephen Mugo, authored an op-ed on agricultural innovation in Africa, published by Thomson Reuters (in English) and Jeune Afrique (in French).

An international team of scientists applied genome-wide association analysis for the first time to study the genetics that underlie grain zinc concentrations in wheat.
Analyzing zinc concentrations in the grain of 330 bread wheat lines across diverse environments in India and Mexico, the researchers uncovered 39 new molecular markers associated with the trait, as well as two wheat genome segments that carry important genes for zinc uptake, translocation, and storage in wheat.
The reported work by wheat scientists paves the way for expanded use of wild grass species, such as Aegilops tauschii (also known as goat grass; pictured here) as sources of new genes for higher grain zinc in wheat. (Photo: Rocio Quiroz/CIMMYT)
A study in Ethiopia found that wheat grown in areas closer to the forest had more nutrients, like zinc and protein. Soils in these areas are rich in organic matter — about 1% higher — due to decomposing trees and plants, as well as manure of livestock grazed in the forest.
Increasing organic matter by 1 percent was associated with an increase in zinc equivalent to meet the daily needs of 0.2 additional people per hectare and an increase in protein equivalent to meeting the daily needs of 0.1 additional people per hectare. These modest increases in soil organic matter contribute a small, but important, increase in nutrients found in wheat.
Although these nutrient increases are not enough to address hidden hunger on their own, they reveal how healthy soils are an additional tool — alongside diet diversity and the biofortification of food — to fight malnutrition.
In 2018 we published our latest annual report, highlighting CIMMYT’s global work and collaboration with partners. It features infographics and case studies from Bangladesh, Ethiopia, Haiti, Mexico and Pakistan.
It is a good way to understand how CIMMYT’s science improves livelihoods around the world.

A man in his early 20s walked the winding roads of Sajiara village, Dumuria upazila, Khulna District in Bangladesh. His head hanging low, he noticed darkness slowly descending and then looked up to see an old farmer wrapping up his own daily activities. With traditional tools in hand, the farmer looked exhausted. The young man, Raju Sarder, considered that there had to be a better way to farm to alleviate his drudgery and that of others in the community.
Determined to act, Raju set out to meet Department of Agricultural Extension (DAE) officials the very next day. They informed him about the Mechanization and Irrigation project of the Cereal Systems Initiative for South Asia (CSISA MI). They also introduced him to the project’s most popular technologies, namely the power tiller operated seeder, reaper and axial flow pumps, all of which reduce labor costs and increase farming efficiency.
Raju found the reaper to be the most interesting and relevant for his work, and contacted a CSISA representative to acquire one.
The first challenge he encountered was the cost — the equivalent of $1,970 — which as a small-scale farmer he could not afford. CSISA MI field staff assured him that his ambitions were not nipped in the bud and guided him in obtaining a government subsidy and a loan of $1,070 from TMSS, one of CSISA MI’s micro financing partners. Following operator and maintenance training from CSISA MI, Raju began providing reaping services to local smallholder rice and wheat farmers.
He noticed immediately that he did not have to exert himself as much as before but actually gained time for leisure and his production costs dwindled. Most remarkably, for reaping 24 hectares Raju generated a profit of $1,806; a staggering 15 times greater than what he could obtain using traditional, manual methods and enough to pay back his loan in the first season.
“There was a time when I was unsure whether I would be able to afford my next meal,” said Raju, “but it’s all different now because profits are pouring in thanks to the reaper.”
As a result of the project and farmers’ interest, field labor in Raju’s community is also being transformed. Gone are the days when farmers toiled from dawn to dusk bending and squatting to cut the rice and wheat with rustic sickles. Laborious traditional methods are being replaced by modern and effective mechanization. Through projects such as CSISA MI, CIMMYT is helping farmers like Raju to become young entrepreneurs with a bright future. Once poor laborers disaffected and treated badly in their own society, these youths now walk with dignity and pride as significant contributors to local economic development.
Support for smallholder farmers to trial and select sustainable practices suited to their varying conditions is essential to build resilient farms needed to feed Africa’s soaring population, said economist Paswel Marenya at the Second African Congress on Conservation Agriculture in Johannesburg this October.
Farmers face different agroecological, socioeconomic and institutional environments across Africa. The mounting challenges brought by climate change also vary from place to place. Family farmers are born innovators, with government and industry support they can develop a resilient farming system that works for them, said the researcher from the International Maize and Wheat Improvement Center (CIMMYT).
One of the emerging paradigms of sustainable agriculture resilient to climatic changes is conservation agriculture — defined by minimal soil disturbance, crop residue retention and diversification through crop rotation. Although not a one-size-fits-all approach, it is a promising framework to be applied and adapted to meet farmers’ unique contexts, he said.
“Conservation agriculture’s potential to conserve soils, improve yields and limit environmental impacts makes it one of the elements that should be given prominence in efforts to secure sustainable and resilient farming in Africa,” he told audiences at the conference dedicated to discuss conservation agriculture systems as the sustainable basis for regional food security.
“Research shows that with a network of appropriate support, farmers can access the tools and knowledge to experiment, learn, adapt and adopt these important principles of conservation agriculture,” he said.
“Their farming can thus evolve to practices that have low environmental impacts, diversify their cropping including intercropping maize with legumes, and test affordable machinery for efficient, timely and labor-saving operations. In the end, each farmer and farming community have the ability to tailor a conservation agriculture-based system based on what works best given their unique socioeconomic settings,” said Marenya.
Trialing sustainable practices leads to adoption
Through the project over 235,000 farming households in the region have trialed sustainable practices reporting positive results of improved soil fertility, reduced labor costs, and increased food production and maize yields despite erratic weather, said collaborating investigator Custudio George from the Mozambique Institute of Agricultural Research.
“The majority of these farmers have gone on to adopt their preferred practices throughout their whole farm and now actively promote conservation agriculture to other farmers,” he added
Women undertake the majority of agricultural activities in sub-Saharan Africa. When they are empowered to try sustainable practices they overwhelmingly adopt those technologies identifying them as an economically viable way to overcome challenges and increase household food security, said Maria da Luz Quinhentos, who is an agronomist with the Mozambique Institute of Agricultural Research.

Forming networks to support farmer resilience
The research project took a multidisciplinary approach bringing together sociologists, economists, agronomists and breeders to study how maize-legume conservation agriculture-based farming can best benefit farmers in seven countries; including Ethiopia, Kenya, Malawi, Mozambique, Tanzania and Uganda.
In this vein, the project sought to connect farmers with multi-sector actors across the maize-legume value chain through Innovation platforms. Innovation Platforms, facilitated by SIMLESA, are multi-stakeholder forums connecting farmer groups, agribusiness, government extension, policy makers and researchers with the common goal to increase farm-level food security, productivity and incomes through the promotion of maize-legume intercropping systems.
“Having a network of stakeholders allows farmers to test and adopt conservation agriculture-based techniques without the risk they would have if they tried and failed alone,” said Michael Misiko who studies farmer adoption as part of SIMLESA.
“Farmers form groups to work with governments to gain access to improved seed, learn new farming practices and connect with local agribusinesses to develop markets for their produce,”
“When new problems arise stakeholders in local and regional innovation platforms can diagnose barriers and together identify mutual solutions,” he said.
Researchers and governments learn from innovation platforms and can use results to recommend productive climate-smart practices to other farmers in similar conditions, Misiko added.
Climate-smart agriculture key to achieve Malabo Declaration
The results from SIMLESA provide African governments with evidence to develop policies that achieve the Malabo Declaration to implement resilient farming systems to enhance food security in the face of a growing climate risks, said Marenya.
If these smallholders are to keep up with food demand of a population set to almost double by 2050 while overcoming challenges they need productive and climate-resilient cropping systems.
CIMMYT research identifies that the defining principles of conservation agriculture are critical but alone are not enough to shield farmers from the impacts of climate change. Complementary improvements in economic policies, markets and institutions — including multi-sectoral linkages between smallholder agriculture and the broader economy — are required to make climate-resilient farming systems more functional for smallholder farmers in the short and long term, said Marenya.
As the world population increases, so does the need for food. “We need to produce more to feed increasing populations and meet dietary demands,” says Tek Sapkota, agricultural systems and climate change scientist at the International Maize and Wheat Improvement Center (CIMMYT). In the case of agriculture, the area of land under cultivation is limited, so increased food production has to come through intensification, Sapkota explains. “Intensification means that you may be emitting more greenhouse gases if you’re applying more inputs, so we need to find a way to sustainable intensification: increase the resilience of production systems, but at the same time decrease greenhouse gas emissions, at least emission intensity.”
Sapkota is involved in a number of global climate change science and policy forums. He represents CIMMYT in India’s GHG platform, a multi-institution platform that regularly prepares greenhouse gas emission estimates at the national and state levels and undertakes relevant policy analyses. Nominated by the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS) and his country, Nepal, he is one of the lead authors of the “special report on climate change and land” of the Intergovernmental Panel on Climate Change (IPCC).
He coordinates climate change mitigation work at CIMMYT. “I am mainly involved in quantification of greenhouse gas emissions and the environmental footprint from agricultural production systems, exploring mitigation options and quantifying their potential at different scales in different regions,” Sapkota says. In addition, he explores low-carbon development activities and the synergies between food production, adaptation and mitigation work within the different components of CIMMYT’s projects.
Agriculture is both a victim of as well as a contributor to climate change, Sapkota explains. “Climate change affects all aspects of food production, because of changes in temperature, changes in water availability, CO2 concentrations, etc.,” he says. “The other side of the coin is that agriculture in general is responsible for about 25 to 32 percent of total greenhouse gas emissions.”
Tek Sapkota (center) stands for a group photo with other scientists working on the IPCC’s special report on climate change and land, at the second lead author meeting in Christchurch, New Zealand, in March 2018.
Measuring emissions and examining mitigation options
A big part of Sapkota’s work is to find ways to mitigate the effects of climate change and the emissions from the agricultural sector. There are three types of mitigation measures, he explains. First, on the supply side, agriculture can “increase efficiency of the inputs used in any production practice.” Second, there’s mitigation from the demand side, “by changing the diet, eating less meat, for example.” Third, by reducing food loss and waste: “About 20 percent of the total food produced for human consumption is being lost, either before harvest or during harvest, transport, processing or during consumption.”
Sapkota and his team analyze different mitigation options, their potential and their associated costs. To that purpose, they have developed methodologies to quantify and estimate greenhouse gas emissions from agricultural products and systems, using field measurement techniques, models and extrapolation.
“You can quantify the emission savings a country can have by following a particular practice” and “help countries to identify the mitigation practices in agriculture that can contribute to their commitments under the Paris climate agreement.”
Their analysis looks at the biophysical mitigation potential of different practices, their national-level mitigation potential, their economic feasibility and scalability, and the country’s governance index and readiness for finance — while considering national food security, economic development and environmental sustainability goals.
This type of research has a global impact. Since agriculture is a contributor to climate change “better management of agricultural systems can contribute to reducing climate change in the future,” Sapkota says. Being an important sector of the economy, “agriculture should contribute its share.”

Impact on farmers
Sapkota’s research is also helping farmers today. Inefficient use of products and inputs is not only responsible for higher greenhouse gas emissions, but it also costs farmers more. “For example, if farmers in the Indo-Gangetic Plain of India are applying 250 to 300 kg of nitrogen per hectare to produce wheat or rice, by following precision nutrient management technologies they can get similar yield by applying less nitrogen, let’s say 150 kg.” As farmers cut production costs without compromising yield, “their net revenue from their products will be increased.”
Farmers may also get immediate benefits from government policies based on the best mitigation options. “Governments can bring appropriate policy to incentivize farmers who are following those kinds of low-emission technologies, for example.”
Farmers could also get rewarded through payments for ecosystem services or for their contribution to carbon credits.
Sapkota is happy that his work is beneficial to farmers. He was born in a small village in the district of Kaski, in the mid-hills of Nepal, and agriculture was his family’s main livelihood. “I really enjoy working with farmers,” he says. “The most fascinating part of my work is going to the field: talking to farmers, listening to them, learning what kind of farming solutions they’re looking for, and so on. This helps refine our research questions to make them more strategic, because the way farmers look at a problem is sometimes entirely different from the way we look at it.”
When he was in Himalaya Secondary School, he studied agriculture as a vocational subject. “I was interested because we were doing farming at home.” This vocation got cemented in university, in the 1990s. When he heard about the agricultural industry and the future opportunities, he decided to pursue a career in science and focus on agriculture. He got his bachelor’s and master’s degree of science in agriculture from the Institute of Agriculture and Animal Science (IAAS), Tribhuvan University, in Nepal.
Tek Sapkota (second from left) and other scientists participate in a small group session during a meeting of lead authors of the Intergovernmental Panel on Climate Change (IPCC).
A global path
He first heard about CIMMYT when he was doing his master’s. “CIMMYT was doing research in maize- and wheat-based plots and systems in Nepal. A few of my friends were also doing their master theses with the financial support of CIMMYT.” After his master’s, he joined an organization called Local Initiatives for Biodiversity, Research and Development (LI-BIRD) which was collaborating with CIMMYT on a maize research program.
After defending his thesis, in 2012, he was working on greenhouse gas measurement in the University of Manitoba, Canada, when he saw an opening at CIMMYT. He joined the organization as a post-doctoral fellow and has been a scientist since 2017. Sapkota considers himself a team player and enjoys working with people from different cultures.
His global experience has enriched his personal perspective and his research work. Through time, he has been able to see the evolution of agriculture and the “dramatic changes” in the way agriculture is practiced in least developed countries like Nepal. “When I was a kid agriculture was more manual … but now, a lot of technologies have been developed and farmers can use them to increase the efficiency of farming”.

KATOWICE, Poland (CIMMYT) — Agricultural scientists attending U.N. COP24 climate talks in Katowice, Poland are discussing a wide range of potential solutions to slow global warming and meet targets laid out in the Paris Agreement on climate change.
The agreement, which has been under intense discussion by negotiators, requires keeping global temperatures in check — to no more than 1.5 degrees Celsius above pre-industrial levels.
Delegates participating in a side event session on agriculture, which produces about a third of global greenhouse gas emissions, discussed the role of soil, presenting scientific evidence of the value of recarbonization. Much of the carbon that was formerly stored in soil, which acts as a carbon sink, has been released into the atmosphere, contributing to global temperature increases.
Majola Mabuza, program officer responsible for policy at the non-profit Southern African Confederation of Agricultural Unions (SACAU), participated in the panel on Monday evening and discussed various risks farmers face and hurdles that need to be overcome.
Mabuza, an agricultural economist, whose research interests span institutional economics of farmers’ organizations, food security and the economics of non-conventional agricultural enterprises, shared some views with CIMMYT about recarbonization.
Q: What is the scale of the role soil plays in climate change?
A: The global carbon pool in soils — at a depth of 2 meters — is three times that of carbon found in the atmosphere. As such, both increases in soil organic carbon and protection against losses from this pool are important strategies for environmental protection. Management practices that raise soil organic carbon have co-benefits such as increased productivity and resilience and can in turn improve food security and sustainable rural development.
Land use changes such as intensification of agriculture or converting grasslands into plow lands often turn them into carbon sources, releasing huge amount of carbon into the atmosphere. The time scales of the source and sink function of soils are fundamentally different: whereas building up belowground carbon stocks takes hundreds or thousands of years, depleting these stocks can be measured in decades or even days, [for example in the case of] forest or grassland fires.
Q: Will soil be the silver bullet to meet food security and climate change goals?
A: Not necessarily a silver bullet. To address climate change and improve food security, a lot is required from various actors. For instance, at this conference, we have learned of food that is produced, but almost a third of it is lost or goes to waste along the chain. Lost or wasted food also contributes to emissions in various forms. So, fixing the issue of soils alone will not win the battle, a lot more issues need to be fixed.
At the production stage, soils have an important role to play in reducing carbon emissions. Soil acts as a sink for carbon, the greenhouse gases that contribute to global warming. Agricultural management approaches such as conservation agriculture and agroforestry simultaneously improve soil carbon, soil fertility and water conservation. More food will be produced on the same land to meet the needs of the growing population.
Q: What will you speak about at the COP24 side event Soils Advantage: Transforming Agriculture by Recarbonizing the Earth’s Soil?
A: Farmers are essentially the managers of land and soils and are by far responsible for whatever happens to the soil. Are farmers, including smallholders, aware of the connection between soil activities and climate change? Do they know the carbon content in their farms? What incentives are there for farmers to build soil organic carbon within their farm plans? What lessons have we learnt with the promotion of such programs as organic farming, conservation agriculture and/or climate-smart agriculture that we can tag along in the drive to transform agriculture by recarbonizing the soil? While some advocate for rewarding better practices or performance on soil carbon in financial markets by attracting higher land values, lower interest rates on loans, or lower insurance premiums, how practical will this be in developing countries where most smallholders do not own the land they produce from?
Q: What is the purpose of recarbonizing?
A: The purpose is essentially to take carbon back to the soil. A lot of human activities, including deforestation, repeated soil tillage — industrial agriculture — and burning of fossil fuels have disrupted the carbon cycle, taking it out of balance. Too much of the carbon that was once in the soil has been released to the atmosphere, hence a lot of it is now in the atmosphere and some in the ocean, but not enough where it once was and where it is more beneficial for sustainable food production and food security — in soil.
Q: How is recarbonization achieved?
A: The most feasible route is to cover the soil with plants and trees, promote organic farming, conservation agriculture, agroforestry, and climate-smart agriculture practices. Plant photosynthesis has the remarkable ability to capture atmospheric CO2, release the oxygen back into the atmosphere, and convert the carbon into sugars, which are used by plants for growth. A considerable proportion of the captured CO2 is released through the plant’s roots to feed soil microorganisms, which in turn assist the plant in acquiring nutrients. Soil microorganisms use this energy to make soil carbon and humus. If left undisturbed, soil humus can lock carbon into place for an average lifetime of hundreds to thousands of years.
Q: Are there efforts underway to do this?
A: Current programs include organic farming, conservation agriculture and climate-smart agriculture.
Q: In terms of wheat and maize, will this have an impact?
A: A great impact. Maize and wheat are the main staples for the poor in Africa and Asia respectively. If we build our soil recarbonizing program around such staple crops.
Q: What is the impact of crop rotations on soil?
A: Crop rotation is an important practice of any sustainable agricultural system. Crop rotation has the following major benefits: It improves soil fertility — as legumes such as groundnuts and beans fix nitrogen in the soil for the benefit of cereals such as maize. Farmers use less chemical fertilizer because legumes in the soil fix the nitrogen naturally. It helps to reduce weeds, diseases and pests by breaking their lifecycles as crops are rotated. It reduces the risk of crop failure in case of drought or disease and improves crop yield.

KATOWICE, Poland (CIMMYT) — Controversies over fossil fuels, indigenous rights and the intricacies of the 2015 Paris Agreement, which was designed to keep global temperatures from rising no more than 1.5 degrees Celsius above pre-industrial levels, are just some of the key topics in focus at U.N. COP24 climate talks.
A vital thread in the climate change narrative, much debated in the corridors of the conference center in Katowice, Poland, is agriculture — a fragile yet vital sector of the global economy which produces about a third of global greenhouse gas emissions.
The member-driven World Farmers Organization (WFO), a group of 1.5 billion farmers from 54 countries, represents the farm community at the United Nations on climate change and other topics, including the Sustainable Development Goals 2030 Agenda.
A new “Climakers” initiative, launched on the sidelines of the COP24 talks, will help address the biggest threat farmers say they fear, according to Luisa Volpe, head of policy development at WFO in an interview. Volpe, who has been with WFO since 2014, formerly worked on farmers programs with the International Fund for Agriculture and Development (IFAD).
“I decided I wanted to move to the other side of the coin and work directly with those who are the targets of big multilateral governmental organizations and government policies,” Volpe said, adding that farmers, tasked with producing more with less for a growing population, are also among those most affected by climate change.
Q: What is the biggest challenge farmers face?
A: The view of the farmers that I represent is that climate is the most important challenge because climate may have an impact on the harvest, on the seeds, on the area where they want to harvest, whether they should move, migration of young farmers to the city, on the kind of products they can produce. Climate change also has an impact on market prices. Of course there are others — they include access to infrastructure, access to financing, having proper insurance and availability and access to financing mechanisms. Farmers say that among this range of issues they may face, climate is probably the most intense because it’s probably the one that they cannot control. They’re just influenced by it and there is little that they can do. Foreseeing weather patterns is very limited — with technology they’re able to predict weather patterns one week before, but not longer. It’s really challenging for them.

Q: How are farmers managing the challenge of climate change?
A: This is something that represents the common ground for all the farmers of the world despite differences in terms of geographical area, in terms of type of business that they manage. Last May in Moscow, during the WFO general assembly, WFO got a unanimous mandate from all of our constituency — made up of national farmers organizations from all over the world — to initiate, establish and propose a new agenda for climate, driven by the farmers themselves. Basically, our members realized that the impact of climate change on farming is something that’s common to all farmers around the world. Their proposal is to first create a broad alliance with the farmers organizations worldwide who may have either a regional voice or a global voice in order to represent all the areas of the world and work together — to join their hands in a new initiative on climate change.
Q: How will the initiative take shape?
A: The outcome of the initiative will be an overarching document with which we as a farmers organization can advocate at the international level and our members can advocate at the national level. What we’re planning to do is to organize a series of regional workshops to meet the farmers themselves and collect case studies and best practices of what farmers are already doing to mitigate and adapt to climate change. Farmers, as all other sectors of the world, are contributing to the causes of climate change. This agenda would not work if we don’t add other actors to the alliance. It’s farmers first, but then a close dialogue with CGIAR.
We’ve started with CCAFS, the CGIAR Research Program on Climate Change, Agriculture and Food Security. We want to work closely with them to make sure that the practices we propose to governments as examples to follow and to scale up when they propose their Nationally Determined Contributions (NDCs) — country level contributions to reducing emissions as part of the Paris Agreement — are effective and science based. Here, we propose to close the gap with science and improve cooperation between farmers and science, so that science really responds to the questions farmers pose — to which they align their practices. In this sense, the scientific research can be more aligned to what farmers actually need, while the farmers may improve their own practices by also responding to the needs of the research.
To really tackle climate change challenges, we need innovation and technologies that are science-based and sustainable, because the main principle of all these agendas is sustainability. What we propose is that farmers contribute by improving their access to innovation research and technology to make their production more sustainable.
Q: Could you explain how you intend to take this practice to a global scale?
A: The other actors we plan to involve are those belonging to the food value chain, because we think that farmers alone cannot be the only solution. That’s why we’re establishing a partnership, for example, with the International Fertilizer Association as well as the International Seeds Federation. We’re in a partnership with Crop Life because they represent a huge element in the food chain. It has to be a global movement if you really want to achieve something that’s effective and efficient. We’ll expand also to other actors in the food chain. We’re also negotiating with multilateral governmental organizations because we need their support for advocacy work we want to do. Governments will become the targets instead of being those who will just propose and impose policies to the farmers. In our view, farmers have the solution in their hands already. What we have to do is to put them in a condition to really influence and feed the political documents that governments will adopt and that will become national policies.

Q: What is Climakers and the farmer-driven climate change agenda you launched at COP24?
A: Climakers are those who become part of the global alliance for this new initiative. The alliance is global, the agenda is farmers-driven. Farmers expressing their needs and their challenges and their best practices — together with science and the multilaterals and the private sector is that of supporting the agenda, supporting the farmers and take it to the governments. Climakers is the name we have chosen for those who are on the farmer side because we think that farmers may make the climate.
Q: In terms of the COP24 negotiations, are you getting any sense of what could be happening that could benefit farmers or are more demands being put on farmers?
A: I see it [as] a very slow process. We were very happy when we saw the concept of food security and food production in the Paris Agreement because although there is no mention of agriculture, at least they mentioned food production. It means that probably some little political will to address the farming sector is there. There is a will to implement the Paris Agreement in the agricultural sector. The negotiation is very slow between north and south regarding the mitigation and adaptation issue, and also the fact that financing for climate change is there, but probably the way it is managed is not really supporting the communities because the channels are too complicated and too long… There are probably some seeds up there, but it’s still a long way. That’s why farmers want to propose an icebreaking agenda.
Q: Are there any other key points you would like to make in the context of climate change?
A: One element that is a little bit controversial for me is critical in the development of agriculture and also in tackling climate change, which is innovation — innovation in terms of practices, in terms of technology, in terms of research, but also in terms of creating financing for farmers and to support rural areas. These have to come from the government side, from the value chain actors, from the farmers themselves and also from the science, from the research centers.
If we close the gap between the farmers and the science, it’s probably the way out for boosting development for the rural areas. We don’t have to be scared of being innovative. Innovation doesn’t mean GMOs. Innovation may also mean an innovative way to treat soils. It may be a new way to access markets, create access to finance for farmers, but also an innovative way to interact between governments and the farmers themselves. To me, innovation is the way out really, that can give a boost to this process.

Agricultural extension materials on best management practices for rice (left) and cauliflower, developed by CIMMYT as part of the NSAF project.
KATHMANDU, Nepal (CIMMYT) — Maintenance and enhancement of soil fertility are vital for food security and environmental sustainability. However, a baseline survey conducted through the Nepal Seed and Fertilizer (NSAF) project shows that 95 percent of farmers have poor agronomic literacy. Most of them have little or no knowledge of proper seed and soil management practices, and do not apply fertilizer appropriately. Many farmers are also unaware of micronutrients and their specific role in crop production, so they spray micronutrient solutions as advised by agrovets. While quality seed and mineral fertilizer use are necessary to improve crop yields, use alone is not sufficient to maximize efficiency — how to use these tools is equally, if not more, important.
All these challenges indicate a need to educate farmers and help them adopt good agronomic practices that will maximize crop production and productivity.
As part of the NSAF project, the International Maize and Wheat Improvement Center (CIMMYT) has developed locally appropriate agricultural extension materials to disseminate best management practices for maize, wheat and other crops. The government of Nepal has endorsed the project’s best management practices for rice, maize, wheat, tomato, cauliflower and onion.
These extension materials have information on integrated soil fertility management: a set of agricultural practices that integrates improved seed, mineral fertilizer use and soil organic matter management, all adapted to local conditions to improve agricultural productivity. They also serve to share information on the 4 Rs of fertilizer management stewardship: right source, right rate, right time and right placement.
CIMMYT and NSAF project partners are delivering these innovative extension materials to agrovets, cooperatives, extension agencies, development organizations and other intermediaries. They then use them to provide training to farmers in their working areas.
Training packages include pictorial aids, games, informative handouts, group activities, field guides, demonstrations, field visits and other physical learning tools. All the materials have been developed following an “active learning” framework. Training topics include the principles of integrated soil fertility management, soil pH and liming, crop-specific fertilizer application rates, planting methods, fertilizer splitting, methods of fertilizer placement, seed and fertilizer quality, handling considerations and postharvest practices.
“Training of extension workers and farmers on agricultural and plant nutrient related topics leads to an improvement in agronomic practices by farmers. Farmers that are trained and educated in best agronomic practices tend to realize high yields,” said Ramananda Gupta, Agronomist and Extension Specialist at the International Fertilizer Development Center (IFDC). CIMMYT is partnering with IFDC to implement the activities of the NSAF project related to fertilizer, including agricultural extension programs, policy support and market development.
All training materials have been field-tested with farmers, agro-dealers, government extension specialists and cooperatives. The training content has been reviewed by the Nepal Agricultural Research Center and Department of Agriculture. “The content of the best management practice materials are essential knowledge and skills farmers need to sustainably intensify production. Adoption of best management practices will significantly contribute in developing the rice sector as well as other related crops,” commented Ram Baran Yadaw, Rice Coordinator at the National Rice Research Program.
The NSAF project team is piloting the dissemination of improved technologies, skills and extension materials to farmers through local governments and private companies, using different tools and methods. The extension materials on best management practices will be publicly available, so improved seed and soil fertility technologies can be more accessible to farmers.
CIMMYT is also partnering with Viamo to adapt all the materials into an SMS and Interactive Voice Response (IVR) system to further scale up the program in the country, potentially reaching 12 million mobile phone subscribers.
The Nepal Seed and Fertilizer (NSAF) project promotes the use of improved seeds and integrated soil fertility management technologies along with effective and efficient extension programs across 21 “Zone of Influence” districts and in five earthquake-affected districts. The project is funded by the United States Agency for International Development (USAID), as part of the Feed the Future initiative. The project is led by International Maize and Wheat Improvement Center (CIMMYT), in collaboration with Nepal’s Ministry of Agricultural Development and partners including the International Fertilizer Development Center (IFDC) and the Center for Environment and Agricultural Research, Extension and Development (CEAPRED).

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.
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 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 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.

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.
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.
