Most African countries have good potential for boosting wheat production if they are supported with technology, innovation and research, said Bekele Abeyo, a senior scientist with the International Maize and Wheat Improvement Center (CIMMYT).
Abeyo, who is based in Ethiopia, which is one of the top wheat-producing countries in Africa, was speaking to BBC Newsday from the International Wheat Congress in the city of Saskatoon in Canada’s western wheat growing province of Saskatchewan.
In Ethiopia, a third of local demand is satisfied by imports, Abeyo said, adding that to reduce import bills, the government is trying to expand wheat production and irrigation in the lowlands where there is high potential for wheat production.
Climate change in Ethiopia and across sub-Saharan Africa is affecting yields, so scientists are working on producing drought-tolerant varieties of wheat. They are also producing biofortified varieties of wheat to help meet nutritional demand for zinc and iron.
More than 800 delegates, including researchers from the CGIAR Research Program on Wheat, CIMMYT, the International Center for Agricultural Research in the Dry Areas (ICARDA), the International Wheat Yield Partnership (IWYP), Cornell University’s Delivering Genetic Gain in Wheat project (DGGW), the University of Saskatchewan and many other organizations are discussing the latest research on wheat germplasm.

Wheat provides 20% of all human calories consumed worldwide. In the Global South, it is the main source of protein and a critical source of life for 2.5 billion people who live on less than $2 a day. Wheat is central to conversations about the rural environment, agricultural biodiversity and global food security.

In the Green Revolution era, the focus for wheat breeders was on boosting yields to feed more people, but today the challenge is not only to increase production on smaller plots of land, but also to improve nutritional quality, said CIMMYT wheat breeder Velu Govindan, during an interview on BBC Newsday.

Smallholder farmers in Nepal tend to apply fertilizer by hand, spreading it as they walk through the field. Under this practice, fertilizer is dispersed randomly and is therefore unevenly distributed among all the seedlings. A recently introduced method, however, helps farmers spread fertilizer in a more uniform, faster and easier way.
The precision spreader is a hand-operated device that ensures an even distribution of fertilizer and is easy to operate. This technology is endorsed by the Cereal Systems Initiative for South Asia (CSISA), a project led by the International Maize and Wheat Improvement Center (CIMMYT) which helps Nepalese farmers adapt measures that are efficient, effective and resilient to the impacts of climate change.
In addition to more consistent distribution, the precision spreader regulates the exact amount of fertilizer required and helps the farmer cover a considerable area with limited movement. This technology has been proven to require less time and effort than the traditional method of broadcasting by hand.
Considering the potential benefits, the CSISA team introduced farmers in Nepal to the precision spreader through training sessions followed by demonstrations of its use. They took place in wheat fields in Bansgadhi, Barbardiya and Duduwa, in Lumbini province, in collaboration with multipurpose cooperative Janaekata and the local governments. Through these sessions, conducted in 45 different sites, more than 650 farmers had a chance to familiarize themselves with the precision spreader, and most of them took a keen interest in incorporating the device into their cropping management practices.
Perhaps the most prominent reason why the precision spreader sparked such interest is that women can easily use it. Most men in rural areas have migrated to the city or abroad in hopes of higher income, so work in the fields has been inadvertently transferred to women. Since Nepal is a predominantly conservative patriarchal society, women have not yet become comfortable and familiarized with all farming practices, especially operating heavy agricultural machinery. However, as expressed by women themselves, the precision spreader is highly convenient to use. Its use could help ease women into the agriculture scene of Nepal and consequently reduce farming drudgery.

Healthier crops, healthier people
Nestled between China and India, Nepal predominantly relies on agriculture for employment. With the majority of its population engaged in the agricultural sector, the country still struggles to produce an adequate food supply for its people, resulting in depressed rural economies, increased malnutrition and widespread hunger.
Sustainable intensification, therefore, is necessary to increase the overall yield and to accelerate agricultural development.
Better distribution of fertilizer in the fields results in a higher chance of healthier crops, which are the source of better nutrition.
A wider use of a seemingly small technology like the precision spreader would not only reduce hardships in farming, but it would also help farmers become more resilient towards the natural and economic adversities they face.
The Cereal Systems Initiative for South Asia (CSISA) is a regional project in Bangladesh, India and Nepal that was established in 2009 with the goal of benefiting more than 8 million farmers by the end of 2020. Funded by the United States Agency for International Development (USAID) and the Bill & Melinda Gates Foundation, CSISA is led by the International Maize and Wheat Improvement Center (CIMMYT) and implemented jointly with the International Food Policy Research Institute (IFPRI) and the International Rice Research Institute (IRRI).

After declining for nearly a decade to around 770 million, in the last three years the number of hungry people has shot up to more than 850 million. At the same time, erratic weather and crop pests and diseases are ruining harvests, intensifying farmers’ risks, and threatening local and global food security.
In an article for Rural 21, I describe how plant breeding has changed over the last four decades and which methods the international research community is developing to master present and future challenges.
SASKATOON, Canada (CIMMYT) — Amid global efforts to intensify the nutritional value and scale of wheat production, scientists from all major wheat growing regions in the world will gather from July 21 to 26, 2019 at the International Wheat Congress in Saskatoon, the city at the heart of Canada’s western wheat growing province, Saskatchewan. The CGIAR Research Program on Wheat (WHEAT), led by the International Maize and Wheat Improvement Center (CIMMYT), is a founding member of the G20 Wheat Initiative, a co-host of the conference.
Wheat provides 20% of all human calories consumed worldwide. In the Global South, it is the main source of protein and a critical source of life for 2.5 billion people who live on less than $2 (C$2.60) a day.
In spite of its key role in combating hunger and malnutrition, the major staple grain faces threats from climate change, variable weather, disease, predators and many other challenges. Wheat’s vital contribution to the human diet and farmer livelihoods makes it central to conversations about the rural environment, agricultural biodiversity and global food security.
More than 800 delegates, including researchers from the CGIAR Research Program on Wheat, CIMMYT, the International Center for Agricultural Research in the Dry Areas (ICARDA), the International Wheat Yield Partnership (IWYP), Cornell University’s Delivering Genetic Gain in Wheat project (DGGW), the University of Saskatchewan and many other organizations worldwide will discuss the latest research on wheat germplasm.
“We must solve a complex puzzle,” said Martin Kropff, CIMMYT’s director general. “Wheat must feed more people while growing sustainably on less land. Wheat demand is predicted to increase 60% in the next three decades, while climate change is putting an unprecedented strain on production.”
“The scientific community is tackling this challenge head-on, through global collaboration, germplasm exchange and innovative approaches. Researchers are looking at wheat’s temperature response mechanisms and using remote sensing, genomics, bio-informatics and other technologies to make wheat more tolerant to heat and drought,” Kropff said.
The congress is the first major gathering of the wheat community since the 2015 International Wheat Conference in Sydney, Australia.
CGIAR and CIMMYT scientists will share the latest findings on:
State-of-the-art approaches for measuring traits to speed breeding for heat and drought tolerance
Breeding durum (pasta) wheat for traits for use in bread products
New sources of diversity — including ancient wheat relatives — to create aphid-resistant wheat and other improved varieties
DNA fingerprinting to help national partners identify gaps in improved variety adoption

Research shows that more than 60% of wheat varietal releases since 1994 were CGIAR-related.
Low- and middle-income countries are the primary focus and biggest beneficiaries of CGIAR wheat research, but high-income countries reap substantial rewards as well. In Canada, three-quarters of the wheat area is sown to CGIAR-related cultivars and in the United States almost 60% of the wheat area was sown to CGIAR-related varieties, according to the research.

CGIAR is a global research partnership for a food secure future dedicated to reducing poverty, enhancing food and nutrition security, and improving natural resources.
About the CGIAR Research Program on Wheat
Joining advanced science with field-level research and extension in lower- and middle-income countries, the Agri-Food Systems CGIAR Research Program on Wheat (WHEAT) works with public and private organizations worldwide to raise the productivity, production and affordable availability of wheat for 2.5 billion resource-poor producers and consumers who depend on the crop as a staple food. WHEAT is led by the International Maize and Wheat Improvement Center (CIMMYT), with the International Center for Agricultural Research in the Dry Areas (ICARDA) as a primary research partner. Funding for WHEAT comes from CGIAR and national governments, foundations, development banks and other public and private agencies, in particular the Australian Centre for International Agricultural Research (ACIAR), the UK Department for International Development (DFID) and the United States Agency for International Development (USAID). www.wheat.org
About CIMMYT
The International Maize and Wheat Improvement Center (CIMMYT) is the global leader in publicly funded maize and wheat research and related farming systems. Headquartered near Mexico City, CIMMYT works with hundreds of partners throughout the developing world to sustainably increase the productivity of maize and wheat cropping systems, thus improving global food security and reducing poverty. CIMMYT is a member of CGIAR and leads the CGIAR Research Programs on Maize and Wheat, and the Excellence in Breeding Platform. The center receives support from national governments, foundations, development banks and other public and private agencies.
Finance is a key driver for agricultural development, as it allows farmers and agribusinesses to improve production efficiency and adopt improved technologies. In Nepal, most of the seed in the formal sector is produced by companies and cooperatives which, like any enterprise, need access to finance in order to grow and increase their capacity.
Nepal’s Agricultural Development Strategy 2015-2035 and National Seed Vision 2013-2025 are key policy documents of the government that provide a roadmap for the development of the agricultural and seed sectors in the country.
In 2017, realizing the need to increase investments in the agricultural sector, the central bank of Nepal, Nepal Rastra Bank, adopted the Priority Sector Lending Programme (PSLP). This program mandates banks and financial institutions to allocate 10% of their loan portfolio to the agricultural sector at a subsidized interest rate of 5%.
The Nepal Seed and Fertilizer (NSAF) project is providing an interface between banks and seed enterprises. Commercial banks are improving their knowledge of the seed sector, its needs and growth opportunities, so they can develop loan products and credit modalities that match the requirements of seed producers and agribusinesses.
These enterprises require finances to upgrade their infrastructure, increase production and grow their businesses. The business plans of seed companies which partner with the NSAF project indicate that the average size of loan required is around $50,000 — 60% for infrastructure development and 40% for working capital. About 66% of the working capital is used to procure raw seed from contract seed growers.

Barriers to lending
Given the huge requirement for finance for seed procurement, access to loans through the PSLP can provide respite to seed companies. However, unlike in other commercial agribusiness, bank lending under the PSLP is uncommon in the seed business, as financial institutions lack understanding of the sector. Many seed companies have not been able to benefit from these loans due to perceived high risks or the lack of business plans and compliance mechanisms required by banks.
In 2018, the NSAF project team assessed the current status, challenges and opportunities in seed business financing through the PSLP. The project also facilitated a seed growers’ lending model through a tripartite agreement between Laxmi Bank Pvt. Limited, Panchashakti Seed Company and seed growers to access loans under PSLP.
On June 14, 2019, NSAF organized a meeting in collaboration with Seed Entrepreneurs Association of Nepal (SEAN) to present findings of their assessments and experiences. The meeting brought together representatives from the Ministry of Agriculture and Livestock Development, national financial institutions, private sector banks, seed companies, agricultural cooperatives and development organizations, who took part in the deliberations and also contributed to refining policy recommendations to enhance seed sector financing.
The assessments showed that PSLP awareness among farmers is low and seed growers borrowing from the informal sector were paying high interest rates, ranging from 24-36% per year. Lack of adequate business plans and compliance mechanisms for seed companies, limited eligibility criteria for PSLP, complex loan acquisition process and collateral issues were some of the factors that made funds largely inaccessible to smallholder farmers. Moreover, the terms and conditions for loan repayment stipulated by banks do not synchronize with the agricultural crop calendar and farm cash flows.

Tailor-made financing solutions
Participants in the meeting discussed ways to create a conducive environment to access financial services for agricultural producers and agribusinesses. Seed companies suggested to improve banks and financial institutions’ understanding of the agricultural markets and build their capacity to assess business opportunities. They also requested that banks simplify the documentation process for acquiring loans for farmers.
Participants from the Kisanka Lagi Unnat Biu-Bijan Karyakram (KUBK), a Nepal government project located in Rupandehi district Province 5, highlighted their model where farmers, organized into cooperatives, are linked to the Small Farmer Development Bank, which could be worth exploring in other sites.
Branchless banking promoted by NSAF is a workable strategy to provide financial services to seed growers in remote areas.
The action research also highlighted that innovative modalities, such as group guarantees, can be a feasible approach to mitigate risks to fund seed growers who do not have land registration certificates and whose land rights have not been transferred in their names. In the case of female producers, this is especially helpful, as many women are the lead decision-makers on the land registered under the name of their husbands, who are migrant workers abroad.
Utilizing the learning from this event, NSAF and SEAN will share the evidence-based policy recommendations with the Ministry of Agriculture and Livestock Development, the Ministry of Finance, the central bank and the Bankers’ Association of Nepal.
Through the NSAF project’s facilitation, banks have approved loans amounting to $2.5 million for business expansion of seven seed companies in 2018. The project will continue to support its seed partners in developing and strengthening their business plans and will facilitate linkages with commercial banks.
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 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.

Halima Begum wanted to increase her income by providing mechanization services to other farmers in Bangladesh’s Chuadanga district, but she was limited by the level of physical effort required. Starting the engine of her tractor was difficult and embarrassing — cranking it required a lot of strength and she had to rely on others to do it for her. She was also afraid she would get injured, like other local service providers.
Women in rural areas of Bangladesh are often hesitant to work in the fields. Social norms, limited mobility, physical exertion, lack of time and other constraints can cause aspiring female entrepreneurs to step back, despite the prospect of higher income. The few women like Halima who do step out of their comfort zone and follow their dreams often have to overcome the physical effort required to operate these machines.
Starting the tractor is a daunting task on its own and the possibility of having to do it multiple times a day adds to the reluctance of ownership.
To make manual cranking a thing of the past for Bangladeshi women entrepreneurs, and to encourage others, the International Maize and Wheat Improvement Center (CIMMYT), through the Cereal Systems Initiative for South Asia-Mechanization and Irrigation (CSISA-MI), is supporting small businesses who manufacture and sell affordable mechanical self-starter attachments for two-wheel tractors.
The self-starter is a simple spring-loaded device mounted over the old crank handle socket, which allows users to start the engine with the flick of a lever.

For women like Begum, manually starting a tractor was a difficult task that is now gone forever.
“I used to struggle quite a lot before, but now I can easily start the machine, thanks to this highly convenient self-starter,” Begum said.
The self-starter reduces the risk of accidents and coaxes hesitant youth and women to become entrepreneurs in the agricultural mechanization service industry.
CIMMYT is supporting businesses like Janata Engineering, which imports self-starter devices and markets them among local service providers in the district of Sorojgonj, Chuadanga district. The project team worked with the owner, Md. Ole Ullah, to organize field demonstrations for local service providers, showing how to use and maintain the self-starter device.
The Cereal Systems Initiative for South Asia-Mechanization and Irrigation (CSISA-MI) is led by the International Maize and Wheat Improvement Center (CIMMYT) and funded by the United States Agency for International Development (USAID). The project focuses on upstream market interventions in Bangladesh, ensuring technologies are reliably available in local markets and supported by an extensive value chain.

A new urgency is being felt on climate change. Schoolchildren are striking, there are protests in the streets, and politicians across the world, including the UK, are pushing to call climate change a national emergency.
A cruel irony is that climate change will not be felt equally by all—those who have contributed the least to rising temperatures are set to suffer the most.

Many maize farmers in sub-Saharan Africa grow old varieties that do not cope well under drought conditions. In the Oromia region of Ethiopia, farmer Sequare Regassa is improving her family’s life by growing the newer drought-tolerant maize variety BH661. This hybrid was developed by the Ethiopian Institute of Agricultural Research (EIAR), using CIMMYT’s drought-tolerant inbred lines and one of EIAR’s lines. It was then officially released in 2011 by the EIAR as part of the Drought Tolerant Maize for Africa (DTMA) project, funded by the Bill & Melinda Gates Foundation and continued under the Stress Tolerant Maize for Africa (STMA) initiative.
“Getting a good maize harvest every year, even when it does not rain much, is important for my family’s welfare,” said Regassa, a widow and mother of four, while feeding her granddaughter with white injera, a flat spongy bread made of white grain maize.
Since her husband died, Regassa has been the only breadwinner. Her children have grown up and established their own families, but the whole extended family makes a living from their eight-hectare farm in Guba Sayo district.

On the two hectares Regassa cultivates on her own, she rotates maize with pepper, sweet potato and anchote, a local tuber similar to cassava. Like many farming families in the region, she grows maize mainly for household food consumption, prepared as bread, soup, porridge and snacks.
Maize represents a third of cereals grown in Ethiopia. It is cheaper than wheat or teff — a traditional millet grain — and in poor households it can be mixed with teff to make the national staple, injera.
In April, as Regassa was preparing the land for the next cropping season, she wondered if rains would be good this year, as the rainy season was coming later than usual.
In this situation, choice of maize variety is crucial.
She used to plant a late-maturing hybrid released more than 25 years ago, BH660, the most popular variety in the early 2000s. However, this variety was not selected for drought tolerance. Ethiopian farmers face increasing drought risks which severely impact crop production, like the 2015 El Nino dry spell, leading to food insecurity and grain price volatility.
Under the DTMA project, maize breeders from CIMMYT and the Ethiopian Institute for Agricultural Research (EIAR) developed promising drought-tolerant hybrids which perform well under drought and normal conditions. After a series of evaluations, BH661 emerged as the best candidate with 10% better on-farm grain yield, higher biomass production, shorter maturity and 34% reduction in lodging, compared to BH660.
The resulting BH661 variety was released in 2011 for commercial cultivation in the mid-altitude sub-humid and transition highlands.
The year after, as farmers experienced drought, the Ethiopian extension service organized BH661 on-farm demonstrations, while breeders from CIMMYT and EIAR organized participatory varietal selection trials. Farmers were impressed by the outstanding performances of BH661 during these demos and trials and asked for seeds right away.
Seed companies had to quickly scale up certified seed production of BH661. The STMA project team assisted local seed companies in this process, through trainings and varietal trials. Companies decided to replace the old hybrid, BH660.

“In addition to drought tolerance, BH661 is more resistant to important maize diseases like Turcicum leaf blight and grey leaf spot,” explained Dagne Wegary, a maize breeder at CIMMYT. “For seed companies, there is no change in the way the hybrid is produced compared to BH660, but seed production of BH661 is much more cost-effective.”
EIAR’s Bako National Maize Research Center supplied breeder seeds to several certified seed producers: Amhara Seed Enterprise (ASE), Bako Agricultural Research Center (BARC), Ethiopian Seed Enterprise (ESE), Oromia Seed Enterprise (OSE) and South Seed Enterprise (SSE). Certified seeds were then distributed through seed companies, agricultural offices and non-governmental organizations, with the technical and extension support of research centers.

From drought risk to clean water
After witnessing the performance of BH661 in a neighbor’s field, Regassa asked advice from her local extension officer and decided to use it. She is now able to produce between 11-12 tons per hectare. She said her family life has changed forever since she started planting BH661.
With higher maize grain harvest, she is now able to better feed her chickens, sheep and cattle. She also sells some surplus at the local market and uses the income for her family’s needs.

“If farmers follow the recommended fertilizer application and other farming practices, BH661 performs much better than the old BH660 variety,” explained Regassa. “If we experience a drought, it may be not that bad thanks to BH661’s drought tolerance.”
Regassa buys her improved seeds from the Bako Research Station, as well as from farmers’ cooperative unions. These cooperatives access seeds from seed companies and sell to farmers in their respective districts. “Many around me are interested in growing BH661. Sometimes we may get less seeds than requested as the demand exceeds the supply,” Regassa said.
She observed that maize prices have increased in recent years. A 100 kg bag of maize that used to sell for 200–400 Ethiopian birr (about $7–14) now sells for 600–700 Ethiopian birr (about $20–23). With the increased farmers’ wealth in her village, families were able to pay collectively for the installation of a communal water point to get easy access to clean water.
“Like women’s role in society, no one can forget the role maize has in our community. It feeds us, it feeds our animals, and cobs are used as fuel. A successful maize harvest every year is a boon for our village,” Regassa concluded.
In 2018, CIMMYT continued to innovate and forge strategic alliances to combat malnutrition, tackle the effects of climate change and respond to emerging threats.
Building on the release of a new wheat genome reference map, our researchers more precisely tagged genes for valuable traits, including disease resistance, heat tolerance, and grain quality, in more than 40,000 CIMMYT wheat lines.
In collaboration with our partners, CIMMYT released 81 maize and 48 wheat varieties. More than 40,000 farmers, scientists and technical workers across the world took part in over 1,500 training and capacity development activities. CIMMYT researchers published 338 journal articles.
As the maize-hungry fall armyworm spreads from Africa to Southeast Asia, CIMMYT joined with more than 40 partners in an international consortium to advance research against the devastating insect pest.
CIMMYT used a scaling approach to extend the benefits of crop research to more farmers and consumers in developing countries in transformative and lasting ways. Smallholder farmers in Mexico, Pakistan and Zimbabwe are benefitting from the use of appropriate machinery and implements for efficient and climate-smart agriculture. A manual developed with the Food and Agriculture Organization (FAO) of the United Nations offers technical and business advice for local entrepreneurs offering mechanized services, such as sowing or threshing, to smallholder farmers.
As part of taste tests in Ethiopia, Kenya, and Tanzania, consumers indicated their willingness to pay a premium for quality protein maize (QPM), which contains enhanced levels of the amino acids needed to synthesize protein.
A CIMMYT-led study on gender has explored the lives and viewpoints of 7,500 men and women from farming communities in 26 countries, providing invaluable information that will lead to better productivity and food security.
2018 showed us that the passion and values of staff and partners help CIMMYT to have major impact on the livelihoods of smallholders and the poor. This Annual Report pays tribute to them.

The burning of crop residue, or stubble, across millions of hectares of cropland between planting seasons is a visible contributor to air pollution in both rural and urban areas of India. (Photo: Dakshinamurthy Vedachalam/CIMMYT)
Groundwater conservation policies are contributing to the air pollution crisis in northwestern India by concentrating agricultural fires into a narrower window when weather conditions favor poor air quality, according to a new study by the International Maize and Wheat Improvement Center (CIMMYT) published on Nature Sustainability.
Facing severe groundwater depletion from intensive crop cultivation, the state governments of Haryana and Punjab introduced separate legislation in 2009 to prohibit early rice establishment in order to reduce water consumption. The study revealed that later rice planting results in later rice harvest, leading to a delayed and condensed period when residues are burned prior to wheat establishment. Consequently, more farmers are setting fire to crop residues at the same time, increasing peak fire intensity by 39%, contributing significantly to atmospheric pollution.
“Despite being illegal, the burning of post-harvest rice residues continues to be the most common practice of crop residue management in northwestern India, and while groundwater policies are helping arrest water depletion, they also appear to be exacerbating one of the most acute public health problems confronting India,” said CIMMYT scientist Balwinder Singh.
“Burning agricultural waste dominantly releases PM2.5 aerosols, a type of fine particulate matter that is particularly harmful to human health,” he explained.

The research results shed light on the sustainability challenges confronting many highly productive agricultural systems, where addressing one problem can exacerbate others, said Andrew McDonald, a professor at Cornell University and co-author of the study.
“Identifying and managing tradeoffs and capitalizing on synergies between crop productivity, resource conservation, and environmental quality is essential,” McDonald said.
“To devise more effective agricultural development programs and policies, integrative assessments are required that meld groundwater, air quality, economic, and technology scaling considerations in common frameworks,” he explained.
The current policy environment in India encourages productivity maximization of cereals and very high levels of residue production especially in the western Indo-Gangetic Plains, according to Bruno Gerard, another author of the study and head of CIMMYT’s Sustainable Intensification Program.
“If these policies are changed, companion efforts must facilitate sustainable intensification in areas such as the Eastern Gangetic Plains, where water resources are relatively abundant and closer coupling of crop-livestock systems provides a diverse set of end-uses for crops residues,” Gerard said.
The way forward
Northwestern India is home to millions of smallholder farmers and a global breadbasket for grain staples, accounting for 85% of the wheat procured by the Indian government. Thus, what happens here has regional and global ramifications for food security.
“A sensible approach for overcoming tradeoffs will embrace agronomic technologies such as the Happy Seeder, a seed drill that plants seeds without impacting crop residue, providing farmers the technical means to avoid residue burning,” said ML Jat, a scientist with CIMMYT who coordinates sustainable intensification programs in northwestern India.
“Through continued efforts on the technical refinement and business model development for the Happy Seeder technology, uptake has accelerated,” he added. “Financial incentives in the form of payments for ecosystem services may provide an additional boost to adoption.”
“Additional agronomic management measure such as cultivation of shorter-duration rice varieties may help arrest groundwater decline while reducing the damaging concentration of agricultural burning,” Jat explained.
The researchers suggested that long-term solutions will likely require crop diversification away from rice towards crops that demand less water, like maize, as recently started by the government in the state of Haryana.
The International Maize and Wheat Improvement Center (CIMMYT) is the global leader in publicly funded maize and wheat research and related farming systems. Headquartered near Mexico City, CIMMYT works with hundreds of partners throughout the developing world to sustainably increase the productivity of maize and wheat cropping systems, thus improving global food security and reducing poverty. CIMMYT is a member of CGIAR and leads the CGIAR Research Programs on Maize and Wheat, and the Excellence in Breeding Platform. The center receives support from national governments, foundations, development banks and other public and private agencies.
On May 15, 2019, as part of the CGIAR System Council meeting held at the ILRI campus in Addis Ababa, Ethiopia, around 200 Ethiopian and international research and development stakeholders convened for the CGIAR Agriculture Research for Development Knowledge Share Fair. This exhibition offered a rare opportunity to bring the country’s major development investors together to learn and exchange about how CGIAR investments in Ethiopia help farmers and food systems be more productive, sustainable, climate resilient, nutritious, and inclusive.
Under the title One CGIAR — greater than the sum of its parts — the event offered the opportunity to highlight close partnerships between CGIAR centers, the Ethiopian government and key partners including private companies, civil society organizations and funding partners. The fair was organized around the five global challenges from CGIAR’s business plan: planetary boundaries, sustaining food availability, promoting equality of opportunity, securing public health, and creating jobs and growth. CGIAR and its partners exhibited collaborative work documenting the successes and lessons in working through an integrated approach.
There were 36 displays in total, 5 of which were presented by CIMMYT team members. Below are the five posters presented.
How can the data revolution help deliver better agronomy to African smallholder farmers?
This sustainability display showed scalable approaches and tools to generate site-specific agronomic advice, developed through the Taking Maize Agronomy to Scale in Africa (TAMASA) project in Nigeria, Tanzania and Ethiopia.

This poster describes how CGIAR works with Ethiopia’s research & development sector to support national food security priorities.
Addressing gender norms in Ethiopia’s wheat sector
Research shows that restrictive gender norms prevent women’s ability to innovate and become productive. This significantly impacts Ethiopia’s economy (over 1% GDP) and family welfare and food security.
Quality Protein Maize (QPM) for better nutrition in Ethiopia
With the financial support of the government of Canada, CIMMYT together with national partners tested and validated Quality Protein Maize as an alternative to protein intake among poor consumers.
Appropriate small-scale mechanization
The introduction of small-scale mechanization into the Ethiopian agriculture sector has the potential to create thousands of jobs in machinery service provision along the farming value chain.

STOCKHOLM, Sweden — Millions of families in Africa and South Asia have improved their diet with a special variety of sweet potato designed to tackle vitamin A deficiency, according to a report published today.
A six-year project, launched in 2013, used a double-edged approach of providing farming families with sweet potato cuttings as well as nutritional education on the benefits of orange-fleshed sweet potato.
The Scaling Up Sweetpotato through Agriculture and Nutrition (SUSTAIN) project, led by the International Potato Center (CIP) and more than 20 partners, reached more than 2.3 million households with children under five with planting material.
The project, which was rolled out in Kenya, Malawi, Mozambique and Rwanda as well as Bangladesh and Tanzania, resulted in 1.3 million women and children regularly eating orange-fleshed sweet potato when available.
“Vitamin A deficiency (VAD) is one of the most pernicious forms of undernourishment and can limit growth, weaken immunity, lead to blindness, and increase mortality in children,” said Barbara Wells, director general of CIP. “Globally, 165 million children under five suffer from VAD, mostly in Africa and Asia.”
“The results of the SUSTAIN project show that agriculture and nutrition interventions can reinforce each other to inspire behavior change towards healthier diets in smallholder households.”
Over the past decade, CIP and partners have developed dozens of biofortified varieties of orange-fleshed sweet potato in Africa and Asia. These varieties contain high levels of beta-carotene, which the body converts into vitamin A.
Just 125g of fresh orange-fleshed sweet potato provides the daily vitamin A needs of a pre-school child, as well as providing high levels of vitamins B6 and C, manganese and potassium.
Under the SUSTAIN project, families in target communities received nutritional education at rural health centers as well as cuttings that they could then plant and grow.
For every household directly reached with planting material, an additional 4.2 households were reached on average through farmer-to-farmer interactions or partner activities using technologies or materials developed by SUSTAIN.
The project also promoted commercial opportunities for smallholder farmers with annual sales of orange-fleshed sweet potato puree-based products estimated at more than $890,000 as a result of the project.

Perspectives from the Global South
The results of the initiative were published during the EAT Forum in Stockholm, where CGIAR scientists discussed the recommendations of the EAT-Lancet report from the perspective of developing countries.
“The SUSTAIN project showed the enormous potential for achieving both healthy and sustainable diets in developing countries using improved varieties of crops that are already widely grown,” said Simon Heck, program leader, CIP.
“Sweet potato should be included as the basis for a sustainable diet in many developing countries because it provides more calories per hectare and per growing month than all the major grain crops, while tackling a major nutrition-related health issue.”
At an EAT Forum side event, scientists highlighted that most food is grown by small-scale producers in low- and middle-income countries, where hunger and undernutrition are prevalent and where some of the largest opportunities exist for food system and dietary transformation.
“There are almost 500 million small farms that comprise close to half the world’s farmland and are home to many of the world’s most vulnerable populations,” said Martin Kropff, director general of the International Maize and Wheat Improvement Center (CIMMYT).
“Without access to appropriate technologies and support to sustainably intensify production, small farmers — the backbone of our global food system — will not be able to actively contribute a global food transformation.”
Matthew Morell, director general of the International Rice Research Institute (IRRI), added: “If the EAT-Lancet planetary health diet guidelines are to be truly global, they will need to be adapted to developing-world realities — such as addressing Vitamin A deficiency through bio-fortification of a range of staple crops.
“This creative approach is a strong example of how to address a devastating and persistent nutrition gap in South Asia and Africa.”
The International Potato Center (CIP) was founded in 1971 as a research-for-development organization with a focus on potato, sweet potato and Andean roots and tubers. It delivers innovative science-based solutions to enhance access to affordable nutritious food, foster inclusive sustainable business and employment growth, and drive the climate resilience of root and tuber agri-food systems. Headquartered in Lima, Peru, CIP has a research presence in more than 20 countries in Africa, Asia and Latin America. CIP is a CGIAR research center. www.cipotato.org
CGIAR is a global research partnership for a food-secure future. CGIAR science is dedicated to reducing poverty, enhancing food and nutrition security, and improving natural resources and ecosystem services. Its research is carried out by 15 CGIAR centers in close collaboration with hundreds of partners, including national and regional research institutes, civil society organizations, academia, development organizations and the private sector. www.cgiar.org

How to scale up agricultural innovation in a sustainable and responsible manner? Through a workshop from the International Maize and Wheat Improvement Center (CIMMYT), a group from Mexico’s state of Chiapas learnt the basic principles of scaling. This knowledge will allow them to design and implement strategies that live well beyond the end of a project and that take into account the systems in which they operate.
Through presentations, group exercises and discussions, 23 people associated with the MasAgro project in Chiapas — technical advisors, coordinators and collaborators — received training on scaling sustainable and responsible agricultural innovations.
The scaling process is relevant because oftentimes the size of a problem does not match the size of its solutions. To support scaling efforts, all relevant actors and entities must subscribe to a paradigm shift to achieve a positive sustainable impact for the greatest number of people.
Executing innovations in scaling requires a paradigm shift in all relevant actors and entities involved in order to achieve positive, sustainable impact that reaches the greatest number of people.
The workshop was divided into three sections. The first section was focused on basic concepts and the definition of realistic and responsible scaling goals. In the second, the group discovered the “Scaling Scan” tool. The third section was focused on the identification of opportunities and potential actions at the project level and through strategic collaborations.
The workshop “Scaling farming innovations: the what, for what and how” took place on April 24 and 25, 2019, in Tuxtla Gutiérrez, Chiapas. The event was led by Lennart Woltering, international scaling expert at CIMMYT, María Boa, CIMMYT scaling coordinator, and Jorge García, CIMMYT Hub Manager from the MasAgro project in Chiapas.
This training was held under the project for Strengthening Market Access for Small Producers of Maize and Legumes in Oaxaca, Chiapas and Campeche, which is financed by the Walmart Foundation.
