Location: Asia

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

The Indian Council of Agricultural Research (ICAR) honored a cropping systems agronomist from the International Maize and Wheat Improvement Center (CIMMYT) with its prestigious Rafi Ahmed Kidwai Award for outstanding and impact-oriented research contributions in natural resource management and agricultural engineering.

M.L. Jat, a native of India and a CIMMYT principal scientist, received the award from Narender Singh Tomar, India’s Union Minister of Agriculture, in New Delhi, as part of ceremonies celebrating ICAR’s 91st Foundation Day on July 16.

The award is given every other year to Indian scientists engaged in research relevant for Indian agriculture. It includes a cash prize of half a million Rupees, about $7,250.

Dedication and achievement making a difference

Jat has worked for more than two decades to benefit farmers and the environment in South Asia’s vast rice-wheat farm belt through the study and promotion of conservation agriculture and better natural resource management practices. These have included reduced or zero-tillage, keeping crop residues on the soil instead of burning or removing them, more precise fertilizer and water use, scale-appropriate mechanization, and the intelligent diversification of crops.

“I’m extremely honored and grateful for this recognition,” said Jat. “With a rising population of 1.6 billion people, South Asia hosts 40% of the world’s poor and malnourished on just 2.4% of its land. Better practices can help farmers adapt to the warmer winters and extreme, erratic weather events such as droughts and floods, which are having a terrible impact.”

The science of Jat and his associates aims to boost the efficiency of use of water, nutrients, and energy, while improving soil health, raising farmers’ profits, and reducing agriculture’s environmental footprint.

Among other contributions, Jat’s efforts have fostered the adoption of precision land levelling for better irrigation and conservation agriculture practices on more than 6 million hectares in India. Research and policy advice by Jat and colleagues helped foster a recent shift in national policy to avoid rice residue burning and mitigate the region’s severe seasonal smog.

Evidence from studies of Jat and co-workers suggests that India could cut nearly 18% of its agricultural greenhouse gas emissions through sustainable and cost-saving farming practices, while helping to achieve the Sustainable Development Goals of reducing poverty and hunger.

Jat has authored or co-authored more than 100 peer-reviewed, widely-cited articles in high impact journals. One recent innovation studied and promoted by Jat and partners involves precision delivery of fertilizer through sub-soil drip irrigation.

“Climate change has complex and local impacts, requiring scalable solutions likewise to be locally-adapted,” explained Jat, who in 2016 received India’s National Academy of Agricultural Sciences fellowship in Natural Resource Management and has been at the forefront of training farmers and young researchers in conservation agriculture and climate-smart practices.

ICAR Foundation Day draws large attendance

The ICAR ceremonies were attended by more than 1,500 stakeholders, including representatives of CGIAR centers and other international agencies; Shri Kailash Choudhary and Shri Purshottam Rupala, Ministers of State for Agriculture and Farmer Welfare; Trilochan Mohapatra, Director General of ICAR and Secretary of India’s Department of Agricultural Research and Education (DARE); along with vice chancellors of state agriculture universities and other senior officers of ICAR, the Ministry of Agriculture, and state governments.

A long-time partner and funder of CIMMYT and one of the world’s largest national agricultural research systems, ICAR is an autonomous organization under DARE in India’s Ministry of Agriculture and Farmers Welfare that encompasses more than 100 institutes and 70 agricultural universities spread across the country.

Precision spreader for fertilizer set to change the agriculture scene in Nepal

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).

Improved access to finance can boost seed business in Nepal

Written by Rodrigo Ordóñez on July 16, 2019. Posted in Features.

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.

Groundwater, the unexpected villain in India’s air pollution crisis

Cranking, a thing of the past

Written by Rodrigo Ordóñez on July 10, 2019. Posted in Features. 1 Comment on Cranking, a thing of the past

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.

Reconciling food security, resource depletion and environmental quality trade-offs in India

Written by Matthew O'Leary on June 28, 2019. Posted in Features.

Northwestern India is home to millions of smallholder farmers making it a breadbasket for grain staples. Since giving birth to the Green Revolution it has continued to increase its food production through rice and wheat farming providing food security to the region.

This high production has not come without shortfalls; groundwater tables are falling from excessive irrigation and climate change has brought erratic rainfall. In response, the state governments of Haryana and Punjab introduced separate legislation forcing farmers to delay rice planting to coincide with the arrival of the monsoonal rains in late June.

With rice sowing pushed back to tackle a looming water crisis, the time available between harvesting rice and planting wheat has been reduced. Consequently, the majority of farmers opt to burn the post-harvest rice straw to quickly prepare their fields for wheat. The majority of the 34 tons of rice residues the region produces is burned in a short window of time, throwing a lot of toxic smoke into the air.

New research, by the International Maize and Wheat Improvement Center (CIMMYT), delved into linkages between groundwater and agricultural burning policies. The study uncovered that groundwater conservation policies in Haryana and Punjab are exacerbating the nation’s air pollution crisis by concentrating crop residue burning in the late fall.

“Despite being illegal, the burning of post-harvest rice residues continues to be the most common practice of crop residue management, 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 – air pollution,” said CIMMYT scientist and author of the study, Balwinder Singh.

Getting to the guts of air pollution’s chokehold on India

Air pollution in India has increased significantly since 2000. Each fall, from late October to November, a toxic fog containing a mixture of dust, carbon and particles covers northwestern India. For the 18.6 million who live in New Delhi the smog not only brings daily life to a standstill but slices years off life expectancy. It kills an estimated 1.5 million people every year, with nearly half of these deaths occurring in the Indo-Gangetic Plains, the northernmost part of the country that includes New Delhi.

The analysis suggests that temporal changes in burning are a prime contributor to the air quality crisis. The limited amount of time to prepare fields for wheat planting has caused fire intensity to increase by 39 percent, peaking in November with a maximum of 681 fires per day. This increase occurs when temperatures in New Delhi are lower and winds are weak. The still conditions trap pollution and limit the amount that can escape.

Recognizing policy tradeoffs is important for sustainable agricultural intensification

Agriculture for development researchers with CIMMYT investigate how best to sustainably intensify food production. This seeks to produce more food, improve nutrition and livelihoods, and boost rural incomes without an increase in inputs – such as land and water – while reducing environmental impacts. Policies can help to shape efforts towards sustainable intensification by encouraging farming practices that save resources and protect the environment. However, it is important that governments strike the right balance between food security, resource depletion and environmental quality.

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,” he said.

Policies to promote sustainable intensification can also burst India’s pollution bubble

Surface crop residue retention and incorporation are the promising on-farm management options to address the issue of burning as well as maintaining soil health and long-term sustainability, said M.L. Jat, a scientist with CIMMYT who coordinates sustainable intensification programs in northwestern India.

Apart from pumping toxic smoke into the air, ash left on fields after residue burning can negatively affect soil health in the long term. However, if residue is mulched into the soil, nutrient levels improve and carbon sequestration capacity increases, lowering the release of greenhouse gases. Additionally, residue retention reduces evaporation and increases soil moisture by as much as 10 percent during the wheat-growing season.

“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,” he explained.

“When rice is ready to be reaped, a tractor or a harvester collects the grain, a spreader distributes the straw that remains on the ground and the Happy Seeder drills into the land to seed wheat,” Jat said. “Farmers no longer need to till the land to plant their wheat, instead they practice a form of conservation agriculture.”

Researchers at CIMMYT and Punjab Agricultural University have undertaken extensive trials in farmer fields and the new technology has proven itself as a step forward for developing viable solution to rice crop residue burning.

The Indian government launched a $157 million initiative to discourage burning through agricultural machinery innovations. However, the Happy Seeder is yet to be adopted widely. It is estimated that to cover 50 percent, 5 million ha, of the total acreage under rice-wheat cropping systems in India, about 60,000 Happy Seeders are needed. At present, there are only about 10,000 available.

A recent policy brief suggests rapid adoption needs a major government push to publicize and popularize the technology. The brief suggests delivery of machinery hire services through Primary Agriculture Cooperative Societies and private entrepreneurs with ongoing government support is a viable tool to equitably reach farmers.

Honoring the life and legacy of Fred Palmer

Written by Mike Listman on June 27, 2019. Posted in News.

Fred Palmer, former CIMMYT maize agronomist, in his office at Egerton University, Kenya, in 1994.

With sorrow we report the passing on June 14 of Anthony F. E. (Fred) Palmer, former maize agronomist and physiologist who contributed notably to the International Maize and Wheat Improvement Center (CIMMYT) networking and capacity building during crucial periods.

A British national, Palmer joined CIMMYT as a post-doctoral fellow in 1968 and retired from the center in 1996. With undergraduate studies in Agronomy at the University of Reading, Palmer completed masters and doctoral degrees in Crop Physiology at Cornell University. His early years at CIMMYT headquarters included work in maize physiology, agronomy and training.

In 1972 Palmer moved to Pakistan, serving as a production agronomist in that key Green Revolution setting until 1978, when he returned to Mexico as a training officer. “Fred was a true gentleman as a researcher and trainer,” said Stephen Waddington, retired CIMMYT maize agronomist who worked with Fred in Africa. “He was a mentor and friend to many junior CIMMYT staff, including myself, and countless trainees and visiting scientists from partner countries.”

Capitalizing on his experience and accomplishments, in 1985 CIMMYT posted Palmer to Nairobi, Kenya, as the team leader of the East African Cereal Project, funded by the Canadian International Development Agency (CIDA). During the project’s third phase, Palmer helped to establish and guide an entry-level crop management training program, in conjunction with the Kenya Agricultural Research Institute (KARI) and Egerton University, targeting maize researchers from eastern and southern Africa. Based at the university’s Njoro campus, the effort included construction of training facilities and guest rooms and Palmer successfully prepared Egerton administrators and faculty to take over the program, according to Joel Ransom, a North Dakota State University professor who served as a CIMMYT maize agronomist in Asia and sub-Saharan Africa.

“Scores of young agronomists mastered the fundamentals of on-farm research through that program,” Ransom said. “Palmer’s mentoring, training, and leadership greatly advanced the professional development of African maize and wheat scientists.”

Matthew Reynolds, CIMMYT distinguished scientist and wheat physiologist, recalls talking to Palmer about the latter’s efforts to apply fledgling tools for measuring photosynthesis in the field, a topic in which he had specialized at Cornell. “Fred was a very kind and unassuming man who treated everyone with respect, qualities that made him a great training officer and a well-regarded colleague,” said Reynolds.

Palmer firmly believed that national partners needed the capacity to train staff, particularly those fresh out of university studies, strengthening both their knowledge and professional linkages.

“By bringing young scientists together and working with them as a multidisciplinary research team,” Palmer wrote in a report on CIMMYT training in eastern and southern Africa, “it is anticipated that these scientists will learn to value each other’s work as essential to successful research.”

The CIMMYT community sends its warmest condolences to the Palmer family.

The case for rushing farmer access to BARI Gom 33

Written by Emma Orchardson on June 26, 2019. Posted in News. 1 Comment on The case for rushing farmer access to BARI Gom 33

In 2016, the emergence of wheat blast, a devastating seed- and wind-borne pathogen, threatened an already precarious food security situation in Bangladesh and South Asia.

In a bid to limit the disease’s impact in the region, the Bangladesh Agricultural Research Institute (BARI) collaborated with the International Maize and Wheat Improvement Center (CIMMYT) and researchers from nearly a dozen institutions worldwide to quickly develop a long-term, sustainable solution.

The result is BARI Gom 33, a new blast-resistant, high-yielding, zinc-fortified wheat variety, which Bangladesh’s national seed board approved for dissemination in 2017. In the 2017-18 season, the Bangladesh Wheat Research Council provided seed for multiplication and the country’s Department of Agricultural Extension established on-farm demonstrations in blast prone districts.

However, the process of providing improved seed for all farmers can be a long one. In a normal release scenario, it can take up to five years for a new wheat variety to reach those who need it, as nucleus and breeder seeds are produced, multiplied and certified before being disseminated by extension agencies. Given the severity of the threat to farmer productivity and the economic and nutritional benefits of the seed, scientists at CIMMYT argue that additional funding should be secured to expedite this process.

According a new study on the economic benefits of BARI Gom 33, 58 percent of Bangladesh’s wheat growing areas are vulnerable to wheat blast. The rapid dissemination of seed can help resource-poor farmers better cope with emerging threats and changing agro-climatic conditions, and would play a significant role in combatting malnutrition through its increased zinc content. It could also have a positive effect on neighboring countries such as India, which is alarmingly vulnerable to wheat blast.

“Our simulation exercise shows that the benefits of disseminating BARI Gom 33 far exceed the seed multiplication and dissemination costs, which are estimated at around $800 per hectare,” explains Khondoker Mottaleb, CIMMYT socioeconomist and lead author of the study. Even in areas unaffected by wheat blast, scaling out BARI Gom 33 could generate a net gain of $8 million for farmers due to its 5 percent higher average yield than other available varieties. These benefits would nearly double in the case of an outbreak in blast-affected or blast-vulnerable districts.

Based on these findings, the authors urge international development organizations and donor agencies to continue their support for BARI Gom 33, particularly for government efforts to promote the blast-resistant variety. The minimum seed requirement to begin the adoption and diffusion process in the 2019-20 wheat season will be 160 metric tons, which will require an initial investment of nearly $1 million for seed multiplication.

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.

Groundwater conservation policies help fuel air pollution crisis in northwestern India, new study finds

Written by Rodrigo Ordóñez on June 17, 2019. Posted in Press releases.

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.

Air pollution in India kills an estimated 1.5 million people every year, with nearly half of these deaths occurring in the Indo-Gangetic Plains, the northernmost part of the country that includes New Delhi.

“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.

“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.

Millions at lower risk of vitamin A deficiency after six-year campaign to promote orange-fleshed sweet potato

Written by Rodrigo Ordóñez on June 13, 2019. Posted in Press releases.

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.”

System uses plants to lure fall armyworm away from maize fields

Written by Rodrigo Ordóñez on June 4, 2019. Posted in News.

Climate conditions in Nepal are suitable for the establishment of fall armyworm, which could cause considerable crop loss if not managed properly. The fall armyworm is a destructive pest that has a voracious appetite for maize and other crops. Through the Nepal Seed and Fertilizer (NSAF) project, the International Maize and Wheat Improvement Center (CIMMYT) is working with the government of Nepal and other partners to address this imminent threat.

Chemical control of fall armyworm is too expensive and impractical for small-scale farmers, has negative human health effects, and can be a source of soil pollutants with a negative effect on biodiversity.

CIMMYT is currently evaluating the efficacy of push-pull cropping systems to control fall armyworm. Considered one of the most climate-smart technologies, push-pull systems use plant-pest ecology instead of harmful chemical insecticides to control weeds and insects. It is an environmentally friendly pest control method which is also economically viable for maize producers.

This system involves two types of crops: Napier grass (Pennisetum purpureum) and silverleaf desmodium legume (Desmodium uncinatum).

Desmodium plants are intercropped with the rows of maize and Napier grass surrounds the maize crop. Desmodium produces volatile chemicals that repel fall armyworm moths, while the Napier grass produces chemicals that attract female moths. The resulting push-pull system takes the pest away from the maize field.

An additional benefit is that desmodium improves nitrogen fertility through biological nitrogen fixation, which may reduce nitrogen input in the long-term. Desmodium also provides ground cover for maize, controlling soil erosion and offering protection from extreme heat conditions. Both desmodium and Napier grass are excellent fodder crops for livestock.

Because of all these reasons, push-pull technology is highly beneficial to smallholders who are dependent on locally available inputs for their subsistence farming. It can also have a positive spiral effect on the environment.

Scientists in other regions are also looking at agro-ecological options to manage fall armyworm.

A burning issue

Written by Rodrigo Ordóñez on June 4, 2019. Posted in Photos.

Pollution has become a part of our daily life: particulate matter in the air we breathe, organic pollutants and heavy metals in our food supply and drinking water. All of these pollutants affect the quality of human life and create enormous human costs.

India is home to 15 of the world’s cities with the highest air pollution, making it a matter of national concern. The country is the world’s third largest greenhouse gas emitter, where agriculture is responsible for 18% of total national emissions.

For decades, CIMMYT has engaged in the development and promotion of technologies to reduce our environmental footprint and conserve natural resources to help improve farmer’s productivity.

Efficient use of nitrogen fertilizers, better management of water, zero-tillage farming, and better residue management strategies offer viable solutions to beat air pollution originating from the agriculture sector. Mitigation measures have been developed, field tested, and widely adopted by farmers across Bangladesh, India, Nepal and Pakistan.

“Multi-lateral impacts of air pollution link directly it to various sustainability issues,” explained Balwinder Singh, Cropping Systems Simulation Modeler at CIMMYT. “The major sustainability issues regarding air quality revolve around the common question: How good is good enough to be sustainable? We need to decide how to balance the sustainable agriculture productivity and hazardous pollution levels. We need to have policies on the regulation of crop burning and in addition to policies surrounding methods to help reach appropriate air quality levels.”

Slow-release nitrogen fertilizers measure up

Written by Rodrigo Ordóñez on June 3, 2019. Posted in Features. 1 Comment on Slow-release nitrogen fertilizers measure up

Maize, rice and wheat are the major staple crops in Nepal, but they are produced using a lot of fertilizer, which may become an environmental hazard if not completely used up in production. Unfortunately, most farmers apply fertilizers in an unbalanced way.

Urea is a common fertilizer used as a nitrogen source by Nepali farmers. If the time of application is not synchronized with crop uptake, the chances of losses through volatilization releasing ammonia and leaching are high, thereby creating environmental hazards in the atmosphere and downstream.

Through the Nepal Seed and Fertilizer (NSAF) project, the International Maize and Wheat Improvement Center (CIMMYT) is testing the application of environmentally friendly slow-release nitrogen fertilizer in maize production.

In particular, CIMMYT researchers examined the nutrient-use efficiency of briquetted urea and polymer-coated urea, also known as PCU.

Using regular urea, the efficiency of nitrogen use in maize is limited to 17 kg of grain per kg of nitrogen. Using briquetted urea and polymer-coated urea, efficiency increased to 24 and 28 kg of grain per kg of nitrogen respectively. A higher efficiency also suggests a reduction in losses to the environment.

Overall, results show that briquetted urea and polymer-coated urea can allow reduced nitrogen inputs by as much as 30-40% while maintaining the same yield levels achieved using current government fertilizer recommendations.

Similar to the maize trials, the application of slow-release nitrogen at a lower amount than the recommended rate in wheat showed similar agronomic results to the application of traditional urea at higher rates. Reduced losses allowed 40-50% less nitrogen fertilizer application but maintained the same yield levels as the current recommendation.

Although the cost of polymer-coated urea is comparatively expensive in the market unless subsidized, farmers applying briquetted urea save money and labor and can obtain 54% more profits.

“Briquetted urea is easy to use compared with traditional urea application, since its one-time application method saves labor. Moreover the yield performance is better,” said Devi Sara Thapa, a farmer from Surkhet district.

Climate change is affecting the yield of crops due to increased exposure to higher temperature, water stress and delayed or reduced monsoons, all impacting farmers’ incomes. The NSAF project promotes early maturing crop varieties that are resilient to such climatic stresses and can yield a positive harvest. The project works with seed companies and Nepal’s Ministry of Agriculture, Livestock and Development to deploy stress resilient maize and rice varieties packaged with cost efficient and effective soil fertility management practices in the project areas.

Researchers are testing and promoting early and extra early maturing open-pollinated varieties that have tolerance to drought or water stress conditions. These varieties are found to yield up to 7.5 tons per hectare and are ready for harvest in less than 100 days. This allows farmers, particularly in the hills and mid hills, to have another crop in the growing season. Such varieties will enhance farmers’ productivity and ensure food security at times of stressful environmental conditions.

CIMMYT is sharing the benefits of adopting these technologies to farmers, cooperatives and ago-dealers, through field demonstrations and farmer field days.

Project staff and partners use seeds and fertilizers that are approved by the Government of Nepal and the United States Agency for International Development’s environmental regulations on pesticide use or support. The team is promoting seed varieties appropriate for specific agroecological conditions and applying best practices on the use and application of fertilizers and integrated soil fertility management.

The Nepal Seed and Fertilizer (NSAF) project, implemented by the International Maize and Wheat Improvement Center (CIMMYT), aims to increase the availability of agriculture technologies to improve productivity in select value chains, including maize, rice, lentils, and high-value vegetables. Through the NSAF project, CIMMYT and its partners work to improve the capacity of the public and private sectors in their respective roles: to strengthen and develop commercial seed and fertilizer value chains and to develop markets systems to disseminate agricultural technologies throughout Nepal.

Farmer and consumer interest has grown for some 60 maize and wheat varieties whose grain features enhanced levels of the essential micronutrients zinc and provitamin A, developed and promoted through collaborations of CIMMYT, HarvestPlus, and partners in 19 countries (Map: Sam Storr/CIMMYT).

Biofortified maize and wheat can improve diets and health, new study shows

Written by Mike Listman on June 3, 2019. Posted in Press releases. 1 Comment on Biofortified maize and wheat can improve diets and health, new study shows

TEXCOCO, Mexico (CIMMYT) — More nutritious crop varieties developed and spread through a unique global science partnership are offering enhanced nutrition for hundreds of millions of people whose diets depend heavily on staple crops such as maize and wheat, according to a new study in the science journal Cereal Foods World.

From work begun in the late 1990s and supported by numerous national research organizations and scaling partners, more than 60 maize and wheat varieties whose grain features enhanced levels of zinc or provitamin A have been released to farmers and consumers in 19 countries of Africa, Asia, and Latin America over the last 7 years. All were developed using conventional cross-breeding.

“The varieties are spreading among smallholder farmers and households in areas where diets often lack these essential micronutrients, because people cannot afford diverse foods and depend heavily on dishes made from staple crops,” said Natalia Palacios, maize nutrition quality specialist at the International Maize and Wheat Improvement Center (CIMMYT) and co-author of the study.

More than 2 billion people worldwide suffer from “hidden hunger,” wherein they fail to obtain enough of such micronutrients from the foods they eat and suffer serious ailments including poor vision, vomiting, and diarrhea, especially in children, according to Wolfgang Pfeiffer, co-author of the study and head of research, development, delivery, and commercialization of biofortified crops at the CGIAR program known as “HarvestPlus.”

“Biofortification — the development of micronutrient-dense staple crops using traditional breeding and modern biotechnology — is a promising approach to improve nutrition, as part of an integrated, food systems strategy,” said Pfeiffer, noting that HarvestPlus, CIMMYT, and the International Institute of Tropical Agriculture (IITA) are catalyzing the creation and global spread of biofortified maize and wheat.

“Eating provitamin A maize has been shown to be as effective as taking Vitamin A supplements,” he explained, “and a 2018 study in India found that using zinc-biofortified wheat to prepare traditional foods can significantly improve children’s health.”

Six biofortified wheat varieties released in India and Pakistan feature grain with 6–12 parts per million more zinc than is found traditional wheat, as well as drought tolerance and resistance to locally important wheat diseases, said Velu Govindan, a breeder who leads CIMMYT’s work on biofortified wheat and co-authored the study.

“Through dozens of public–private partnerships and farmer participatory trials, we’re testing and promoting high-zinc wheat varieties in Afghanistan, Ethiopia, Nepal, Rwanda, and Zimbabwe,” Govindan said. “CIMMYT is also seeking funding to make high-zinc grain a core trait in all its breeding lines.”

Pfeiffer said that partners in this effort are promoting the full integration of biofortified maize and wheat varieties into research, policy, and food value chains. “Communications and raising awareness about biofortified crops are key to our work.”
