Theme: Nutrition, health and food security

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

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

Best of 2018: Editors’ picks

Written by Rodrigo Ordóñez on . Posted in Features.

In 2018, our editors continued to cover exciting news and events related to maize and wheat science around the world. Altogether, we published more than 200 stories.

It is impossible to capture all of the places and topics we reported on, but here are some highlights and our favorite stories of the year.

Thank you for being a loyal reader of CIMMYT’s news and features. We are already working on new stories and platforms for 2019. Stay tuned!

New technical guide to help farmers protect against fall armyworm

In response to the spread of the fall armyworm across Africa, CIMMYT and its partners published a technical guide for integrated pest management. Produced by international experts, it offers details on the best management practices to help smallholder farmers effectively and safely control the pest while simultaneously protecting people, animals and the environment.

The voracious fall armyworm was on the news again in July, as its presence was reported in India, giving this issue a global scale.

CIMMYT and IITA are co-leading the new Fall Armyworm R4D International Consortium, composed of 40 partners, which held an international conference in Ethiopia in October.

Cobs & Spikes podcast: Blue maize opportunities for Mexican farmers

This year we launched our new podcast, Cobs & Spikes, where you can listen to stories from the field, interviews and explainers.

The most popular episode so far was about blue maize, a distinctive feature of Mexico’s food culture. Valued for its rich flavor and texture, it is also catching the attention of some food processing companies and high-end culinary markets. CIMMYT researchers are helping Mexican farmers tap into two emerging markets that could boost incomes while conserving culture and biodiversity.

Scientists confirm value of whole grains and wheat for nutrition and health

A review of scientific studies on cereal grains and health showed that gluten- or wheat-free diets are not inherently healthier for the general populace and may actually put individuals at risk of dietary deficiencies.

Based on a compilation of 12 reports, eating whole grains is actually beneficial for brain health and associated with reduced risk of diverse types of cancer, coronary disease, diabetes, hypertension, obesity and overall mortality.

African youth find entrepreneurial opportunity in agricultural mechanization

Mechanized agricultural services have traditionally only been used by large-scale farmers who could afford them, but small and medium-sized machines are fast becoming affordable options for family farmers through the advent of service providers. An increasing number of young people across eastern and southern Africa are creating a stable living as entrepreneurs, providing agricultural mechanization services.

CIMMYT is offering training courses to promote mechanization in Ethiopia, Kenya, Tanzania and Zimbabwe. Trainings equip entrepreneurs with essential business skills and knowledge, tailored to rural environments, so they can support farmers with appropriate mechanization services that sustainably intensify their production.

New wheat gene map will speed breeding and help secure grain supplies

In a scientific breakthrough, the International Wheat Genome Sequencing Consortium presented an annotated reference genome with a detailed analysis of gene content among subgenomes and the structural organization for all the chromosomes. The research was published on Science.

A BBC news report on this discovery mentioned CIMMYT as a leader in wheat research to help feed the world’s rapidly expanding population.

Better together: Partnership around zinc maize improves nutrition in Guatemala

Over 46 percent of children under five in Guatemala suffer from chronic malnutrition. More than 40 percent of Guatemala’s rural population is deficient in zinc, an essential micronutrient that plays a crucial role in pre-natal and post-natal development and is key to maintaining a healthy immune system.

CIMMYT is working with partners HarvestPlus and Semilla Nueva to reduce malnutrition and zinc deficiency in the country, through the development and deployment of Guatemala’s first biofortified zinc-enriched maize.

Last year we also reported on the release of a new zinc-enriched maize variety in Colombia and how vitamin A orange maize is improving nutrition in Zimbabwe.

International experts discuss progress and challenges of maize research and development in Asia

More than 280 delegates from 20 countries gathered in Ludhiana, in the Indian state of Punjab, for the 13th Asian Maize Conference and Expert Consultation on Maize for Food, Feed, Nutrition and Environmental Security.

Technical sessions and panel discussions covered topics such as novel tools and strategies for increasing genetic gains, stress-resilient maize, sustainable intensification of maize-based cropping systems, specialty maize, processing and value addition, and nutritionally enriched maize for Asia.

Four young people were distinguished in the first edition of the 2018 MAIZE-Asia Youth Innovators Award. One of them wrote a blog about her personal story and her commitment to make hunger history.

Researchers find “hotspot” regions in the wheat genome for high zinc content, new study shows

An international team of scientists applied genome-wide association analysis for the first time to study the genetics that underlie grain zinc concentrations in wheat.

Analyzing zinc concentrations in the grain of 330 bread wheat lines across diverse environments in India and Mexico, the researchers uncovered 39 new molecular markers associated with the trait, as well as two wheat genome segments that carry important genes for zinc uptake, translocation, and storage in wheat.

Around the same time, a study confirmed the nutritional and health benefits of zinc-biofortified wheat in India. It showed that when vulnerable young children in India consume foods with wheat-enriched zinc, the number of days they spend sick with pneumonia and vomiting significantly diminishes.

Study in Ethiopia links healthy soils to more nutritious cereals

A study in Ethiopia found that wheat grown in areas closer to the forest had more nutrients, like zinc and protein. Soils in these areas are rich in organic matter — about 1% higher — due to decomposing trees and plants, as well as manure of livestock grazed in the forest.

Increasing organic matter by 1 percent was associated with an increase in zinc equivalent to meet the daily needs of 0.2 additional people per hectare and an increase in protein equivalent to meeting the daily needs of 0.1 additional people per hectare. These modest increases in soil organic matter contribute a small, but important, increase in nutrients found in wheat.

Although these nutrient increases are not enough to address hidden hunger on their own, they reveal how healthy soils are an additional tool — alongside diet diversity and the biofortification of food — to fight malnutrition.

A man in his early 20s walked the winding roads of Sajiara village, Dumuria upazila, Khulna District in Bangladesh. His head hanging low, he noticed darkness slowly descending and then looked up to see an old farmer wrapping up his own daily activities. With traditional tools in hand, the farmer looked exhausted. The young man, Raju Sarder, considered that there had to be a better way to farm to alleviate his drudgery and that of others in the community.

Determined to act, Raju set out to meet Department of Agricultural Extension (DAE) officials the very next day. They informed him about the Mechanization and Irrigation project of the Cereal Systems Initiative for South Asia (CSISA MI). They also introduced him to the project’s most popular technologies, namely the power tiller operated seeder, reaper and axial flow pumps, all of which reduce labor costs and increase farming efficiency.

Raju found the reaper to be the most interesting and relevant for his work, and contacted a CSISA representative to acquire one.

The first challenge he encountered was the cost — the equivalent of $1,970 — which as a small-scale farmer he could not afford. CSISA MI field staff assured him that his ambitions were not nipped in the bud and guided him in obtaining a government subsidy and a loan of $1,070 from TMSS, one of CSISA MI’s micro financing partners. Following operator and maintenance training from CSISA MI, Raju began providing reaping services to local smallholder rice and wheat farmers.

He noticed immediately that he did not have to exert himself as much as before but actually gained time for leisure and his production costs dwindled. Most remarkably, for reaping 24 hectares Raju generated a profit of $1,806; a staggering 15 times greater than what he could obtain using traditional, manual methods and enough to pay back his loan in the first season.

“There was a time when I was unsure whether I would be able to afford my next meal,” said Raju, “but it’s all different now because profits are pouring in thanks to the reaper.”

As a result of the project and farmers’ interest, field labor in Raju’s community is also being transformed. Gone are the days when farmers toiled from dawn to dusk bending and squatting to cut the rice and wheat with rustic sickles. Laborious traditional methods are being replaced by modern and effective mechanization. Through projects such as CSISA MI, CIMMYT is helping farmers like Raju to become young entrepreneurs with a bright future. Once poor laborers disaffected and treated badly in their own society, these youths now walk with dignity and pride as significant contributors to local economic development.

CSISA MI is a partnership involving the International Maize and Wheat Improvement Center (CIMMYT) and iDE, a non-governmental organization that fosters farmers’ entrepreneurial development, with funding from USAID under the Feed the Future initiative.

International experts discuss progress and challenges of maize research and development in Asia

Written by Jennifer Johnson on . Posted in Features.

The importance of maize in Asian cropping systems has grown rapidly in recent years, with several countries registering impressive growth rates in maize production and productivity. However, increasing and competing demands — food, feed, and industry — highlight the continued need to invest in maize research for development in the region. Maize experts from around the world gathered to discuss these challenges and how to solve them at the 13th Asian Maize Conference and Expert Consultation on Maize for Food, Feed, Nutrition and Environmental Security, held from October 8 to 10, 2018, in Ludhiana, Punjab, India.

More than 280 delegates from 20 countries attended the conference. Technical sessions and panel discussions covered diverse topics such as novel tools and strategies for increasing genetic gains, stress-resilient maize, sustainable intensification of maize-based cropping systems, specialty maize, processing and value addition, and nutritionally enriched maize for Asia.

The international conference was jointly organized by the Indian Council of Agricultural Research (ICAR), the International Maize and Wheat Improvement Center (CIMMYT), the Indian Institute of Maize Research (ICAR-IIMR), Punjab Agricultural University (PAU), the CGIAR Research Program on Maize (MAIZE), and the Borlaug Institute for South Asia (BISA).

In Asia, maize is rapidly growing in its importance, due to high demand. Maize productivity in the region is growing by 5.2 percent annually compared to a global average of 3.5 percent. However, this is not enough. “Asia produces nearly 80 million tons of maize annually, but demand will be double by the year 2050,” said Martin Kropff, CIMMYT director general, in his opening address at the conference. “We need to produce two times more maize in Asia, using two times less inputs, including water and nutrients. Climatic extremes and variability, especially in South and South East Asia, will make this challenge more difficult. Continued funding for maize research is crucial. We need to work together to ensure that appropriate innovations reach the smallholder farmers.”

Climate-resilient maize and sustainable intensification

A major theme emphasized at the conference was climate resilience in maize-based systems. South Asia is a hotspot for vulnerability due to climate change and climate variability, which poses great risks to smallholder farmers. “Climate resilience cannot be brought by only a single technology — it has to be through a judicious mix of several approaches,” said B.M. Prasanna, director of CIMMYT’s Global Maize Program and the CGIAR Research Program on Maize.

Great advances have been made in developing climate-resilient maize for Asia since the last Asian Maize Conference, held in 2014. Many new heat- and drought-tolerant maize varieties have been developed through various projects, such as the Heat Stress Tolerant Maize for Asia (HTMA), and Affordable, Accessible, Asian (AAA) maize projects. Through the HTMA project, over 50 CIMMYT-derived elite heat-tolerant maize hybrids have been licensed to public and private sector partners in Asia during the last three years, and nine heat-tolerant maize hybrids have been released so far in Bangladesh, India and Nepal.

Sustainable intensification of maize-based farming systems has also helped farmers to increase yields while reducing environmental impact, through conservation agriculture and scale-appropriate mechanization. Simple technologies are now available to reduce harvest time by up to 80 percent and hired labor costs by up to 60 percent. Researchers across the region are also working to strengthen the maize value chains.

Science and appropriate technologies

CIMMYT has been focusing on developing and deploying new technologies that can enhance the efficiency of maize breeding programs; these include doubled haploid (DH) technology, high-throughput field-based phenotyping, and genomics-assisted breeding. The conference emphasized on the need for Asian institutions to adapt such new tools and technologies in maize breeding programs.

Another topic of interest was the fall armyworm, an invasive insect pest that has spread through 44 countries in Africa and was recently reported in India for the first time. “This pest can migrate very quickly and doesn’t require visas and passports like we do. It will travel, and Asian nations need to be prepared,” Prasanna said. “However, there is no need for alarm. We will be looking at lessons learned from other regions and will work together to control this pest.”

In addition to grain for food and feed, specialty maize varieties can provide beneficial economic alternatives for smallholder maize farmers. Conference participants had the opportunity to hear from Indian farmers Kanwal Singh Chauhan and Yugandar Y, who have effectively adopted specialty maize varieties, such as baby corn, sweet corn and popcorn, into life-changing economic opportunities for farming communities. They hope to inspire other farmers in the region to do the same.

On October 10, conference delegates participated in a maize field day organized at the BISA farm in Ladhowal, Ludhiana. Nearly 100 improved maize varieties developed by CIMMYT, ICAR and public and private sector partners were on display, in addition to scale-appropriate mechanization options, decision support tools, and precision nutrient and water management techniques.

The conference concluded with a ceremony honoring the winners of the 2018 MAIZE-Asia Youth Innovators Award. The awards were launched in collaboration between the CGIAR Research Program on Maize and YPARD (Young Professionals for Agricultural Development) to recognize the contributions of innovative young women and men who can inspire fellow youth to get involved in improving maize-based agri-food systems in Asia. Winners of the first edition of the awards include Dinesh Panday of Nepal, Jie Xu of China, Samjhana Khanal of Nepal, and Vignesh Muthusamy of India.

With multi-sector support for climate-sensitive practices, African farmers can boost food security and resilience

Written by Matthew O'Leary on . Posted in Features.

Support for smallholder farmers to trial and select sustainable practices suited to their varying conditions is essential to build resilient farms needed to feed Africa’s soaring population, said economist Paswel Marenya at the Second African Congress on Conservation Agriculture in Johannesburg this October.

Farmers face different agroecological, socioeconomic and institutional environments across Africa. The mounting challenges brought by climate change also vary from place to place. Family farmers are born innovators, with government and industry support they can develop a resilient farming system that works for them, said the researcher from the International Maize and Wheat Improvement Center (CIMMYT).

One of the emerging paradigms of sustainable agriculture resilient to climatic changes is conservation agriculture — defined by minimal soil disturbance, crop residue retention and diversification through crop rotation. Although not a one-size-fits-all approach, it is a promising framework to be applied and adapted to meet farmers’ unique contexts, he said.

“Conservation agriculture’s potential to conserve soils, improve yields and limit environmental impacts makes it one of the elements that should be given prominence in efforts to secure sustainable and resilient farming in Africa,” he told audiences at the conference dedicated to discuss conservation agriculture systems as the sustainable basis for regional food security.

Along with eleven other researchers, Marenya presented evidence gathered over eight years researching the development of locally-adapted conservation agriculture-based practices as part of the Sustainable Intensification of Maize and Legume Systems for Food Security in Eastern and Southern Africa (SIMLESA).

“Research shows that with a network of appropriate support, farmers can access the tools and knowledge to experiment, learn, adapt and adopt these important principles of conservation agriculture,” he said.

“Their farming can thus evolve to practices that have low environmental impacts, diversify their cropping including intercropping maize with legumes, and test affordable machinery for efficient, timely and labor-saving operations. In the end, each farmer and farming community have the ability to tailor a conservation agriculture-based system based on what works best given their unique socioeconomic settings,” said Marenya.

Trialing sustainable practices leads to adoption

Through the project over 235,000 farming households in the region have trialed sustainable practices reporting positive results of improved soil fertility, reduced labor costs, and increased food production and maize yields despite erratic weather, said collaborating investigator Custudio George from the Mozambique Institute of Agricultural Research.

“The majority of these farmers have gone on to adopt their preferred practices throughout their whole farm and now actively promote conservation agriculture to other farmers,” he added

Women undertake the majority of agricultural activities in sub-Saharan Africa. When they are empowered to try sustainable practices they overwhelmingly adopt those technologies identifying them as an economically viable way to overcome challenges and increase household food security, said Maria da Luz Quinhentos, who is an agronomist with the Mozambique Institute of Agricultural Research.

Forming networks to support farmer resilience

The research project took a multidisciplinary approach bringing together sociologists, economists, agronomists and breeders to study how maize-legume conservation agriculture-based farming can best benefit farmers in seven countries; including Ethiopia, Kenya, Malawi, Mozambique, Tanzania and Uganda.

In this vein, the project sought to connect farmers with multi-sector actors across the maize-legume value chain through Innovation platforms. Innovation Platforms, facilitated by SIMLESA, are multi-stakeholder forums connecting farmer groups, agribusiness, government extension, policy makers and researchers with the common goal to increase farm-level food security, productivity and incomes through the promotion of maize-legume intercropping systems.

“Having a network of stakeholders allows farmers to test and adopt conservation agriculture-based techniques without the risk they would have if they tried and failed alone,” said Michael Misiko who studies farmer adoption as part of SIMLESA.

“Farmers form groups to work with governments to gain access to improved seed, learn new farming practices and connect with local agribusinesses to develop markets for their produce,”

“When new problems arise stakeholders in local and regional innovation platforms can diagnose barriers and together identify mutual solutions,” he said.

Researchers and governments learn from innovation platforms and can use results to recommend productive climate-smart practices to other farmers in similar conditions, Misiko added.

Climate-smart agriculture key to achieve Malabo Declaration

The results from SIMLESA provide African governments with evidence to develop policies that achieve the Malabo Declaration to implement resilient farming systems to enhance food security in the face of a growing climate risks, said Marenya.

Hotter temperatures, increased dry spells and erratic rainfall are major concerns to farmers, who produce the majority of the region’s food almost entirely on rain-fed farms without irrigation.

If these smallholders are to keep up with food demand of a population set to almost double by 2050 while overcoming challenges they need productive and climate-resilient cropping systems.

CIMMYT research identifies that the defining principles of conservation agriculture are critical but alone are not enough to shield farmers from the impacts of climate change. Complementary improvements in economic policies, markets and institutions — including multi-sectoral linkages between smallholder agriculture and the broader economy — are required to make climate-resilient farming systems more functional for smallholder farmers in the short and long term, said Marenya.

Nearly 3,000 smallholder wheat farmers throughout Pakistan will begin to sow seed of newer, high-yielding, disease-resistant wheat varieties and spread the seed among their peers in 2019, through a dynamic initiative that is revitalizing the contribution of science-based innovation for national agriculture.

Some 73 tons of seed of 15 improved wheat varieties recently went out to farmers in the provinces of Baluchistan, Gilgit Baltistan, Khyber Pakhtunkhwa, Punjab and Sindh, as part of the Agricultural Innovation Program (AIP), an initiative led by the International Maize and Wheat Improvement Center (CIMMYT) with funding from the US Agency for International Development (USAID).

“Our main goal is to help farmers replace outdated, disease-susceptible wheat varieties,” said Muhammad Imtiaz, CIMMYT scientist and country representative for Pakistan who leads the AIP. “Studies have shown that some Pakistan farmers grow the same variety for as long as 10 years, meaning they lose out on the superior qualities of newer varieties and their crops may fall victim to virulent, rapidly evolving wheat diseases.”

With support from CIMMYT and partners, participating farmers will not only enjoy as much as 20 percent higher harvests, but have agreed to produce and share surplus seed with neighbors, thus multiplying the new varieties’ reach and benefits, according to Imtiaz.

He said the new seed is part of AIP’s holistic focus on better cropping systems, including training farmers in improved management practices for wheat.

Wheat is Pakistan’s number-one food crop. Farmers there produce over 25 million tons of wheat each year — nearly as much as the entire annual wheat output of Africa or South America.

Annual per capita wheat consumption in Pakistan averages over 120 kilograms, among the highest in the world and providing over 60 percent of Pakistanis’ daily caloric intake.

The seed distributed includes varieties that offer enhanced levels of grain zinc content. The varieties were developed by CIMMYT in partnership with HarvestPlus, a CGIAR research program to study and deliver biofortified foods.

According to a 2011 nutrition survey, 39 percent of children in Pakistan and 48 percent of pregnant women suffer from zinc deficiency, leading to child stunting rates of more than 40 percent and high infant mortality.

“I am very excited to be part of Zincol-16 seed distribution, because its rich ingredients of nutrition will have a good impact on the health of my family,” said Munsif Ullah, a farmer from Swabi District, Khyber Pakhtunkhwa province.

Other seed distributed includes that of the Pakistan-13 variety for rainfed areas of Punjab, Shahkar-13 for the mountainous Gilgit-Baltistan, Ehsan-16 for rainfed areas in general, and the Umeed-14 and Zardana varieties for Baluchistan.

All varieties feature improved resistance to wheat rust diseases caused by fungi whose strains are mutating and spreading quickly in South Asia.

CIMMYT and partners are training farmers in quality seed production and setting up demonstration plots in farmers’ fields to create awareness about new varieties and production technologies, as well as collecting data to monitor the varieties’ performance.

They are also promoting resource-conserving practices such as balanced applications of fertilizer based on infrared sensor readings, ridge planting, and zero tillage. These innovations can save water, fertilizer, and land preparation costs, not to mention increasing yields.

“CIMMYT’s main focus in Pakistan is work with national wheat researchers to develop and spread better wheat production systems,” Imtiaz explained. “This includes improved farming practices and wheat lines that offer higher yields, disease resistance, and resilience under higher temperatures and dry conditions, as well as good end-use quality.”

CIMMYT’s partners in AIP include the National Rural Support Program (NRSP), the Lok Sanjh Foundation, the Village Friends Organization (VFO), the Aga Khan Rural Support Program (AKRSP), the National Agricultural Research Council (NARC) Wheat Program, the Wheat Research Institute (WRI) Faisalabad and Sakrand centers, AZRI-Umarkot, Kashmala Agro Seed Company, ARI-Quetta, BARDC-Quetta, and Model Farm Services Center, KP.

Breaking Ground: Tek Sapkota finds ways to reduce emissions from agriculture without compromising food security

Written by Rodrigo Ordóñez on . Posted in Features.

Breaking Ground Postcard TEK SAPKOTA

As the world population increases, so does the need for food. “We need to produce more to feed increasing populations and meet dietary demands,” says Tek Sapkota, agricultural systems and climate change scientist at the International Maize and Wheat Improvement Center (CIMMYT). In the case of agriculture, the area of land under cultivation is limited, so increased food production has to come through intensification, Sapkota explains. “Intensification means that you may be emitting more greenhouse gases if you’re applying more inputs, so we need to find a way to sustainable intensification: increase the resilience of production systems, but at the same time decrease greenhouse gas emissions, at least emission intensity.”

Sapkota is involved in a number of global climate change science and policy forums. He represents CIMMYT in India’s GHG platform, a multi-institution platform that regularly prepares greenhouse gas emission estimates at the national and state levels and undertakes relevant policy analyses. Nominated by the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS) and his country, Nepal, he is one of the lead authors of the “special report on climate change and land” of  the Intergovernmental Panel on Climate Change (IPCC).

He coordinates climate change mitigation work at CIMMYT. “I am mainly involved in quantification of greenhouse gas emissions and the environmental footprint from agricultural production systems, exploring mitigation options and quantifying their potential at different scales in different regions,” Sapkota says. In addition, he explores low-carbon development activities and the synergies between food production, adaptation and mitigation work within the different components of CIMMYT’s projects.

Agriculture is both a victim of as well as a contributor to climate change, Sapkota explains. “Climate change affects all aspects of food production, because of changes in temperature, changes in water availability, CO2 concentrations, etc.,” he says. “The other side of the coin is that agriculture in general is responsible for about 25 to 32 percent of total greenhouse gas emissions.”

Tek Sapkota (center) stands for a group photo with other scientists working on the IPCC’s special report on climate change and land, at the second lead author meeting in Christchurch, New Zealand, in March 2018.

Measuring emissions and examining mitigation options

A big part of Sapkota’s work is to find ways to mitigate the effects of climate change and the emissions from the agricultural sector. There are three types of mitigation measures, he explains. First, on the supply side, agriculture can “increase efficiency of the inputs used in any production practice.” Second, there’s mitigation from the demand side, “by changing the diet, eating less meat, for example.” Third, by reducing food loss and waste: “About 20 percent of the total food produced for human consumption is being lost, either before harvest or during harvest, transport, processing or during consumption.”

Sapkota and his team analyze different mitigation options, their potential and their associated costs. To that purpose, they have developed methodologies to quantify and estimate greenhouse gas emissions from agricultural products and systems, using field measurement techniques, models and extrapolation.

“You can quantify the emission savings a country can have by following a particular practice” and “help countries to identify the mitigation practices in agriculture that can contribute to their commitments under the Paris climate agreement.”

Their analysis looks at the biophysical mitigation potential of different practices, their national-level mitigation potential, their economic feasibility and scalability, and the country’s governance index and readiness for finance — while considering national food security, economic development and environmental sustainability goals.

Recently, Sapkota and his colleagues completed a study quantifying emissions from the agricultural sector in India and identifying the best mitigation options.

This type of research has a global impact. Since agriculture is a contributor to climate change “better management of agricultural systems can contribute to reducing climate change in the future,” Sapkota says. Being an important sector of the economy, “agriculture should contribute its share.”

Impact on farmers

Sapkota’s research is also helping farmers today. Inefficient use of products and inputs is not only responsible for higher greenhouse gas emissions, but it also costs farmers more. “For example, if farmers in the Indo-Gangetic Plain of India are applying 250 to 300 kg of nitrogen per hectare to produce wheat or rice, by following precision nutrient management technologies they can get similar yield by applying less nitrogen, let’s say 150 kg.” As farmers cut production costs without compromising yield, “their net revenue from their products will be increased.”

Farmers may also get immediate benefits from government policies based on the best mitigation options. “Governments can bring appropriate policy to incentivize farmers who are following those kinds of low-emission technologies, for example.”

Farmers could also get rewarded through payments for ecosystem services or for their contribution to carbon credits.

Sapkota is happy that his work is beneficial to farmers. He was born in a small village in the district of Kaski, in the mid-hills of Nepal, and agriculture was his family’s main livelihood. “I really enjoy working with farmers,” he says. “The most fascinating part of my work is going to the field: talking to farmers, listening to them, learning what kind of farming solutions they’re looking for, and so on. This helps refine our research questions to make them more strategic, because the way farmers look at a problem is sometimes entirely different from the way we look at it.”

When he was in Himalaya Secondary School, he studied agriculture as a vocational subject. “I was interested because we were doing farming at home.” This vocation got cemented in university, in the 1990s. When he heard about the agricultural industry and the future opportunities, he decided to pursue a career in science and focus on agriculture. He got his bachelor’s and master’s degree of science in agriculture from the Institute of Agriculture and Animal Science (IAAS), Tribhuvan University, in Nepal.

A global path

He first heard about CIMMYT when he was doing his master’s. “CIMMYT was doing research in maize- and wheat-based plots and systems in Nepal. A few of my friends were also doing their master theses with the financial support of CIMMYT.” After his master’s, he joined an organization called Local Initiatives for Biodiversity, Research and Development (LI-BIRD) which was collaborating with CIMMYT on a maize research program.

Sapkota got a PhD in Agriculture, Environment and Landscapes from the Sant’Anna School of Advanced Studies in Italy, including research in Aarhus University, Denmark.

After defending his thesis, in 2012, he was working on greenhouse gas measurement in the University of Manitoba, Canada, when he saw an opening at CIMMYT. He joined the organization as a post-doctoral fellow and has been a scientist since 2017. Sapkota considers himself a team player and enjoys working with people from different cultures.

His global experience has enriched his personal perspective and his research work. Through time, he has been able to see the evolution of agriculture and the “dramatic changes” in the way agriculture is practiced in least developed countries like Nepal. “When I was a kid agriculture was more manual … but now, a lot of technologies have been developed and farmers can use them to increase the efficiency of farming”.

The maize lethal necrosis (MLN) artificial inoculation screening site in Naivasha, Kenya, will begin its phenotyping (screening/ indexing) cycle of 2019 at the beginning of January 2019 and in other four intervals throughout the year. Interested organizations from both the private and public sectors are invited to send maize germplasm for screening.

In 2013, the International Maize and Wheat Improvement Center (CIMMYT) and the Kenya Agricultural & Livestock Research Organization (KALRO) jointly established the MLN screening facility at the KALRO Naivasha research station in Kenya’s Rift Valley with support from the Bill & Melinda Gates Foundation and the Syngenta Foundation for Sustainable Agriculture.

MLN was first discovered in Kenya in 2011 and quickly spread to other parts of eastern Africa; the disease causes premature plant death and unfilled, poorly formed maize cobs, and can lead to up to 100 percent yield loss in farmers’ fields.

CIMMYT and partners are dedicated to stopping the spread of this deadly maize disease by effectively managing the risk of MLN on maize production through screening and identifying MLN-resistant germplasm. The MLN screening facility supports countries in sub-Saharan Africa to screen maize germplasm (for hybrid, inbred and open pollinated varieties) against MLN in a quarantined environment.

This is the largest dedicated MLN screening facility in East Africa. Since its inception in 2013, the facility has evaluated more than 180,000 accessions (more than 270,000 rows of maize) from more than 15 multinational and national seed companies and national research programs.

Partners can now plan for annual MLN Phenotyping (Screening / Indexing) during 2019 with the schedule below. The improved and streamlined approach for MLN phenotyping should enable our partners to accelerate breeding programs to improve resistance for Maize MLN for sub-Saharan Africa.

2019 annual phenotyping (indexing / screening) schedule:

When the seeds are available  Planting Period – Planned MLN Screening / Indexing
December Second Week of January MLN Indexing
March Second week of April MLN Screening
June Second Week of July MLN Indexing
August Second Week of September MLN Screening
October Second week of November MLN Indexing

More information about the disease and resources for farmers can be found on CIMMYT’s MLN portal.

Please note that it can take up to six weeks to process imports and clear shipments.

New publications: Climate change impact and adaptation for wheat protein

Written by Courtney Brantley on . Posted in Publications.

Globally, wheat provides around 20 percent of the calories and protein in human diets. By mid-century, crop production must increase by 60 percent to meet global food demand and help reduce hunger, a challenge made even harder by climate change. “Climate Change Impact and Adaptation for Wheat Protein,” a study published in Global Change Biology in September 2018, examines why wheat grain protein concentration — a determinant of grain quality — is often overlooked in relation to improving global crop production in the face of climate change challenges.

“The impact of climate change on crops typically focuses on productivity; however, there are nutritional implications too,” says key contributor to the study Matthew Reynolds, wheat physiologist at the International Maize and Wheat Improvement Center (CIMMYT). “Since wheat also provides a significant proportion of protein in the diets of millions of resource-poor people, the negative impact of increased atmospheric CO2 on protein concentration in the grain is a disturbing fact,” stated Reynolds. “If not addressed, it could have a devastating impact on the health and livelihoods especially of marginalized people who cannot easily afford diverse sources of protein in their diet.”

Multi-location field trials, in addition to model testing, were used to systematically analyze the effects of increasing temperature, heat shocks, elevated atmospheric CO2 concentration, nitrogen, water deficiency and the combination of these factors on yield and wheat grain protein in the world’s main wheat producing regions. This study marked the first time that heat shock and high temperature interaction with elevated CO2 concentration was tested through an impact model. As noted in the study, “This is the most comprehensive study ever done of the effect of climate change on yield and the nutritional quality of one of the three major sources of human food security and nutrition.”

Farmers cite climate change as biggest challenge, says World Farmers Organization at COP24 talks

KATOWICE, Poland (CIMMYT) — Controversies over fossil fuels, indigenous rights and the intricacies of the 2015 Paris Agreement, which was designed to keep global temperatures from rising no more than 1.5 degrees Celsius above pre-industrial levels, are just some of the key topics in focus at U.N. COP24 climate talks.

A vital thread in the climate change narrative, much debated in the corridors of the conference center in Katowice, Poland, is agriculture — a fragile yet vital sector of the global economy which produces about a third of global greenhouse gas emissions.

The member-driven World Farmers Organization (WFO), a group of 1.5 billion farmers from 54 countries, represents the farm community at the United Nations on climate change and other topics, including the Sustainable Development Goals 2030 Agenda.

A new “Climakers” initiative, launched on the sidelines of the COP24 talks, will help address the biggest threat farmers say they fear, according to Luisa Volpe, head of policy development at WFO in an interview. Volpe, who has been with WFO since 2014, formerly worked on farmers programs with the International Fund for Agriculture and Development (IFAD).

“I decided I wanted to move to the other side of the coin and work directly with those who are the targets of big multilateral governmental organizations and government policies,” Volpe said, adding that farmers, tasked with producing more with less for a growing population, are also among those most affected by climate change.

Q: What is the biggest challenge farmers face?

A: The view of the farmers that I represent is that climate is the most important challenge because climate may have an impact on the harvest, on the seeds, on the area where they want to harvest, whether they should move, migration of young farmers to the city, on the kind of products they can produce. Climate change also has an impact on market prices. Of course there are others — they include access to infrastructure, access to financing, having proper insurance and availability and access to financing mechanisms. Farmers say that among this range of issues they may face, climate is probably the most intense because it’s probably the one that they cannot control. They’re just influenced by it and there is little that they can do. Foreseeing weather patterns is very limited — with technology they’re able to predict weather patterns one week before, but not longer. It’s really challenging for them.

Q: How are farmers managing the challenge of climate change?

A: This is something that represents the common ground for all the farmers of the world despite differences in terms of geographical area, in terms of type of business that they manage. Last May in Moscow, during the WFO general assembly, WFO got a unanimous mandate from all of our constituency — made up of national farmers organizations from all over the world — to initiate, establish and propose a new agenda for climate, driven by the farmers themselves. Basically, our members realized that the impact of climate change on farming is something that’s common to all farmers around the world. Their proposal is to first create a broad alliance with the farmers organizations worldwide who may have either a regional voice or a global voice in order to represent all the areas of the world and work together — to join their hands in a new initiative on climate change.

Q: How will the initiative take shape?

A: The outcome of the initiative will be an overarching document with which we as a farmers organization can advocate at the international level and our members can advocate at the national level. What we’re planning to do is to organize a series of regional workshops to meet the farmers themselves and collect case studies and best practices of what farmers are already doing to mitigate and adapt to climate change. Farmers, as all other sectors of the world, are contributing to the causes of climate change. This agenda would not work if we don’t add other actors to the alliance. It’s farmers first, but then a close dialogue with CGIAR.

We’ve started with CCAFS, the CGIAR Research Program on Climate Change, Agriculture and Food Security. We want to work closely with them to make sure that the practices we propose to governments as examples to follow and to scale up when they propose their Nationally Determined Contributions (NDCs) — country level contributions to reducing emissions as part of the Paris Agreement — are effective and science based. Here, we propose to close the gap with science and improve cooperation between farmers and science, so that science really responds to the questions farmers pose — to which they align their practices. In this sense, the scientific research can be more aligned to what farmers actually need, while the farmers may improve their own practices by also responding to the needs of the research.

To really tackle climate change challenges, we need innovation and technologies that are science-based and sustainable, because the main principle of all these agendas is sustainability. What we propose is that farmers contribute by improving their access to innovation research and technology to make their production more sustainable.

Q: Could you explain how you intend to take this practice to a global scale?

A: The other actors we plan to involve are those belonging to the food value chain, because we think that farmers alone cannot be the only solution. That’s why we’re establishing a partnership, for example, with the International Fertilizer Association as well as the International Seeds Federation. We’re in a partnership with Crop Life because they represent a huge element in the food chain. It has to be a global movement if you really want to achieve something that’s effective and efficient. We’ll expand also to other actors in the food chain. We’re also negotiating with multilateral governmental organizations because we need their support for advocacy work we want to do. Governments will become the targets instead of being those who will just propose and impose policies to the farmers. In our view, farmers have the solution in their hands already. What we have to do is to put them in a condition to really influence and feed the political documents that governments will adopt and that will become national policies.

Q: What is Climakers and the farmer-driven climate change agenda you launched at COP24?

A: Climakers are those who become part of the global alliance for this new initiative. The alliance is global, the agenda is farmers-driven. Farmers expressing their needs and their challenges and their best practices — together with science and the multilaterals and the private sector is that of supporting the agenda, supporting the farmers and take it to the governments. Climakers is the name we have chosen for those who are on the farmer side because we think that farmers may make the climate.

Q: In terms of the COP24 negotiations, are you getting any sense of what could be happening that could benefit farmers or are more demands being put on farmers?

A: I see it [as] a very slow process. We were very happy when we saw the concept of food security and food production in the Paris Agreement because although there is no mention of agriculture, at least they mentioned food production. It means that probably some little political will to address the farming sector is there. There is a will to implement the Paris Agreement in the agricultural sector. The negotiation is very slow between north and south regarding the mitigation and adaptation issue, and also the fact that financing for climate change is there, but probably the way it is managed is not really supporting the communities because the channels are too complicated and too long… There are probably some seeds up there, but it’s still a long way. That’s why farmers want to propose an icebreaking agenda.

Q: Are there any other key points you would like to make in the context of climate change?

A: One element that is a little bit controversial for me is critical in the development of agriculture and also in tackling climate change, which is innovation — innovation in terms of practices, in terms of technology, in terms of research, but also in terms of creating financing for farmers and to support rural areas. These have to come from the government side, from the value chain actors, from the farmers themselves and also from the science, from the research centers.

If we close the gap between the farmers and the science, it’s probably the way out for boosting development for the rural areas. We don’t have to be scared of being innovative. Innovation doesn’t mean GMOs. Innovation may also mean an innovative way to treat soils. It may be a new way to access markets, create access to finance for farmers, but also an innovative way to interact between governments and the farmers themselves. To me, innovation is the way out really, that can give a boost to this process.

Breeders find strength in diversity at EiB contributor meeting

Written by Sam Storr on . Posted in Features.

Around 115 members of the CGIAR breeding community, plus others representing national programs, universities, funders and the private sector, met for a three-day discussion of how to co-develop the next generation of advanced breeding programs that will improve the rate at which resource-poor farmers are able to adopt improved varieties that meet their needs.

The annual Excellence in Breeding Platform (EiB) Contributor’s meeting, held this year in Amsterdam from 13-15 November, caps a year of engagement with CGIAR Centers and national agricultural research system (NARS) partners around the world.

“Although breeding is one of the oldest functions in CGIAR, we have never had a meeting like this with scientists from all the centers,” said Michael Baum, director of Biodiversity and Crop Improvement at the International Center for Agricultural Research in the Dry Areas, (ICARDA). “Within CGIAR, plant breeding started as a science, but now we are looking at how to implement it not as a science but as an operation, as it is done in the private sector, so there are many new concepts.”

Key items on the agenda for November were new tools to develop product profiles and create improvement plans that will define the modernization agenda in each center and across the Platform itself, based in part on the Breeding Program Assessment Tool (BPAT) that most Centers completed in 2018.

The conversation was enriched by Paul Kimani (University of Nairobi) presenting on the Demand-led Variety Design project, which produced the book, “The Business of Plant Breeding.”

Ranjitha Puskur, gender research coordinator at the International Rice Research Institute (IRRI), started an animated discussion on how to incorporate gender into product design by thinking about customer segments.

Tim Byrne from AbacusBio introduced methods for identifying farmer preferences to be targeted by breeding programs.

In breakout sessions, contributors were able to have detailed discussions according to their various specializations: phenotyping, genotyping and bioinformatics/data management. The direct feedback from contributors will be incorporated into EiB workplans for training and tool development for the coming year.

A key outcome of the meeting was an agreement to finalize the product profile tool, to be made available to EiB members in early December 2018. The tool helps breeders to work with other specialisms, such as markets, socioeconomics and gender, to define the key traits needed in new products for farmers. This helps to focus breeding activities towards areas of greatest impact, supports NARS to play a greater role, and creates accountability and transparency for donors, in part by defining the geographic areas being targeted by programs.

“Breeding trees is different to the annual crops,” said Alice Muchugi, genebank manager at the World Agroforestry Centre (ICRAF), “but we are seeing what we can borrow from our colleagues. By uploading what we are doing in maps, for example, donors are able to perceive the specific challenges we are undertaking.”

“I think we have realized there are lot of challenges in common, and the Platform is helping us all work on those,” said Filippo Bassi, durum wheat breeder at ICARDA. “I like to see all the people around the room, if you look at the average age there is a big shift; the number of countries present also tells you a lot.”

Tabare Abadie, R&D external academic outreach lead at Corteva Agriscience, also saw the meeting as a good opportunity to meet a broader group of people. “One of the take homes I hear is [that] there are a lot of challenges, but also a lot of communication and understanding. For me as a contributor it’s an incentive to keep supporting EiB, because we have gone through those changes before [at Corteva], and we can provide some know-how and experience of what happens,” Abadie explained.

“There are still a lot of gaps to fill, but this is a good start,” said Thanda Dhliwayo, maize breeder at the International Maize and Wheat Improvement Center (CIMMYT). “We need to get everyone involved, from leadership down to the guys working in the field.”

International coalition keeps devastating maize disease at bay, but risks still linger

Written by Jérôme Bossuet on . Posted in Features.

NAIROBI, Kenya (CIMMYT) — When maize lethal necrosis (MLN) was first reported in Bomet County, Kenya, in September 2011 and spread rapidly to several countries in eastern Africa, agricultural experts feared this emerging maize disease would severely impact regional food security. However, a strong partnership across eight countries between maize research, plant health organizations and the private seed sector has, so far, managed to contain this devastating viral disease, which can wipe out entire maize fields. As another emerging pest, the fall armyworm, is making headlines in Africa, African countries could learn a lot from the initiatives to combat MLN on how to rapidly respond to emerging crop pests and diseases.

On November 19-20, 2018, the International Maize and Wheat Improvement Center (CIMMYT), national research and plant protection agencies and seed companies met in Nairobi to review the third year’s progress of the MLN Diagnostics and Management Project, supported by USAID. All participants agreed that preventing any spread of the disease into southern Africa was a great success.

“The fact that we all responded rapidly and productively to this crisis serves as a testament of the success of our collective efforts,” said CIMMYT’s Global Maize Program Director, B.M. Prasanna, while addressing delegates from Ethiopia, Kenya, Malawi, Rwanda, Tanzania, Uganda, Zambia and Zimbabwe. “That no new country has reported the MLN outbreak since Ethiopia last reported it in the 2014-2015 period, and that we have managed to keep it at bay from southern Africa and west Africa is no mean feat. It would have been a major food security disaster if the disease had spread throughout sub-Saharan Africa.”

However, the MLN Community of Practice warned that risks of severe outbreaks remain, with new cases of MLN reported during the MLN 2018 survey in several parts of Uganda.

Rapid response to a food security threat

MLN is caused by the combination of the maize chlorotic mottle virus (MCMV) and other common cereal viruses mostly from the potyviridae family — a set of viruses that encompasses over 30 percent of known plant viruses — like the sugarcane mosaic virus (SCMV). This viral disease can result in up to 100 percent yield loss and has devastated the incomes and food security situation of many smallholder farmers in the region.

CIMMYT, in collaboration with national agricultural research institutions, national plant protection agencies and seed sector partners, developed a multi-layered response system including real-time intensive surveillance, screening, and fast-tracking of the MLN resistance breeding program. Thanks to the MLN Screening Facility in Naivasha, Kenya, maize breeders rapidly discovered that most popular maize varieties were susceptible, which could expose poor farmers to the risk of losing their entire maize crops.

Using its global collection of maize lines and numerous crop improvement innovations, CIMMYT was able to develop and release at least 15 MLN-resistant maize varieties in just 2 to 3 years.

One important step was to understand how the disease spread. Epidemiologists quickly pointed out the necessity to work with the seed companies and farmers, as the virus could be transmitted through seeds. The project helped put in place the protocols for seed firms to adhere to for their products to be MLN-free. Affordable and simple seed treatment procedures yielded promising results. The project also created awareness on better farming methods for effective disease control.

National Plant Protection Organizations were mobilized to create intensive awareness. They were also equipped and trained on low-cost innovative field diagnostic tools like MLN immunostrips and the deployment of GPS-based mobile surveillance and reporting systems.

“For the first time, Rwanda was able to conduct a comprehensive survey on MLN in farmers’ fields, commercial seed fields and at agro-dealers. We are glad that through MLN management and awareness programs within the project, MLN incidences have declined,” said Fidele Nizeyimana, maize breeder and pathologist at the Rwanda Agricultural Board (RAB) and the MLN Surveillance team lead in Rwanda.

“Equally important is that the commercial seed sector took the responsibility of testing their seed production fields, made sure that seed exchange is done in a responsible manner and implemented voluntary monitoring and surveillance within their fields,” remarked Francis Mwatuni, MLN project manager at CIMMYT.

“I am happy that Malawi has maintained its MLN-free status as per the intensive MLN surveillance activities we conducted in the country over the last three years,” noted Johnny Masangwa, senior research officer and MLN Surveillance team lead in Malawi. “We are now able to monitor both seed and grain movement through our borders for MLN traces, courtesy of the lab equipment, reagents and training on laboratory analysis we received through the project”.

B.M. Prasanna, director of the CGIAR Research Program on Maize (MAIZE), discusses what the CGIAR offers in rapid response preparedness to newly emerging pests, diseases and crises.

The maize sector should remain vigilant

Daniel Bomet, maize breeder at Uganda’s National Agricultural Research Organization (NARO), warned that with new infections reported in the northern parts of his country, the maize sector needs to remain alert to the threat of MLN. “We need to step up MLN awareness and management programs, and require seed companies to follow the right procedures to produce MLN-free seeds to arrest this trend,” he said.

Tanzania Seed Association Executive Director, Bob Shuma, also warned that MLN could be spreading to the southern highlands of the country as the virus was detected in some seed shipments from three seed companies operating in that region. A comprehensive MLN survey in Tanzania will hopefully soon give an idea of the countrywide status of the disease in the country.

Conference speakers and participants noted that inefficient regulatory processes in maize seed variety release and deployment still stand in the way of rapid release of MLN resistant varieties to farmers across the region.

“How quickly we scale up and deploy the elite MLN-resistant and stress-tolerant varieties to the farmer is the next most important phase of the project,” Prasanna said.

The Kenya Plant Health Inspectorate Service (KEPHIS) General Manager, Phytosanitary Services, Isaac Macharia, said that with the support of the USAID Feed the Future program, the government agency has set up a team dedicated to assisting seed companies doing seed multiplication to fast-track the release of the MLN-resistant varieties to the market. Some Kenyan seed companies announced they will market MLN-resistant varieties for the next cropping season in March 2019.

As the project enters its last year, the MLN Community of Practice looks to ensure the fully functional pest surveillance and management system it has put in place is sustainable beyond the project’s life.

KATHMANDU, Nepal (CIMMYT) — Maintenance and enhancement of soil fertility are vital for food security and environmental sustainability. However, a baseline survey conducted through the Nepal Seed and Fertilizer (NSAF) project shows that 95 percent of farmers have poor agronomic literacy. Most of them have little or no knowledge of proper seed and soil management practices, and do not apply fertilizer appropriately. Many farmers are also unaware of micronutrients and their specific role in crop production, so they spray micronutrient solutions as advised by agrovets. While quality seed and mineral fertilizer use are necessary to improve crop yields, use alone is not sufficient to maximize efficiency — how to use these tools is equally, if not more, important.

All these challenges indicate a need to educate farmers and help them adopt good agronomic practices that will maximize crop production and productivity.

As part of the NSAF project, the International Maize and Wheat Improvement Center (CIMMYT) has developed locally appropriate agricultural extension materials to disseminate best management practices for maize, wheat and other crops. The government of Nepal has endorsed the project’s best management practices for rice, maize, wheat, tomato, cauliflower and onion.

These extension materials have information on integrated soil fertility management: a set of agricultural practices that integrates improved seed, mineral fertilizer use and soil organic matter management, all adapted to local conditions to improve agricultural productivity. They also serve to share information on the 4 Rs of fertilizer management stewardship: right source, right rate, right time and right placement.

CIMMYT and NSAF project partners are delivering these innovative extension materials to agrovets, cooperatives, extension agencies, development organizations and other intermediaries. They then use them to provide training to farmers in their working areas.

Training packages include pictorial aids, games, informative handouts, group activities, field guides, demonstrations, field visits and other physical learning tools. All the materials have been developed following an “active learning” framework. Training topics include the principles of integrated soil fertility management, soil pH and liming, crop-specific fertilizer application rates, planting methods, fertilizer splitting, methods of fertilizer placement, seed and fertilizer quality, handling considerations and postharvest practices.

“Training of extension workers and farmers on agricultural and plant nutrient related topics leads to an improvement in agronomic practices by farmers. Farmers that are trained and educated in best agronomic practices tend to realize high yields,” said Ramananda Gupta, Agronomist and Extension Specialist at the International Fertilizer Development Center (IFDC). CIMMYT is partnering with IFDC to implement the activities of the NSAF project related to fertilizer, including agricultural extension programs, policy support and market development.

All training materials have been field-tested with farmers, agro-dealers, government extension specialists and cooperatives. The training content has been reviewed by the Nepal Agricultural Research Center and Department of Agriculture. “The content of the best management practice materials are essential knowledge and skills farmers need to sustainably intensify production. Adoption of best management practices will significantly contribute in developing the rice sector as well as other related crops,” commented Ram Baran Yadaw, Rice Coordinator at the National Rice Research Program.

The NSAF project team is piloting the dissemination of improved technologies, skills and extension materials to farmers through local governments and private companies, using different tools and methods. The extension materials on best management practices will be publicly available, so improved seed and soil fertility technologies can be more accessible to farmers.

CIMMYT is also partnering with Viamo to adapt all the materials into an SMS and Interactive Voice Response (IVR) system to further scale up the program in the country, potentially reaching 12 million mobile phone subscribers.

The Nepal Seed and Fertilizer (NSAF) project promotes the use of improved seeds and integrated soil fertility management technologies along with effective and efficient extension programs across 21 “Zone of Influence” districts and in five earthquake-affected districts. The project is funded by the United States Agency for International Development (USAID), as part of the Feed the Future initiative. The project is led by International Maize and Wheat Improvement Center (CIMMYT), in collaboration with Nepal’s Ministry of Agricultural Development and partners including the International Fertilizer Development Center (IFDC) and the Center for Environment and Agricultural Research, Extension and Development (CEAPRED).

A wheat self-sufficiency roadmap for Ethiopia’s future

Written by Jérôme Bossuet on . Posted in Features.

The Ethiopian government announced recently that the country should become wheat self-sufficient over the next four years. Why is boosting domestic wheat production important for this country in the Horn of Africa, and could wheat self-sufficiency be attained in the next four years? The Ethiopian Institute for Agricultural Research (EIAR), with the support of International Maize and Wheat Improvement Center (CIMMYT), gathered agriculture and food experts from the government, research and private sectors on November 23, 2018, to draw the first outlines of this new Ethiopian wheat initiative.

The low-tech domestic wheat farming and price support issue

Despite a record harvest of 4.6 million metric tons in 2017, Ethiopia imported 1.5 million tons of wheat the same year, costing US$600 million. Population growth, continuous economic growth and urbanization over the last decade has led to a rapid change in Ethiopian diets, and the wheat sector cannot keep up with the growing demand for pasta, dabo, ambasha and other Ethiopian breads.

The majority of Ethiopia’s 4.2 million wheat farmers cultivate this cereal on an average of 1.2-hectare holdings, with three quarters produced in Arsi, Bale and Shewa regions. Most prepare the land and sow with draft animal power equipment and few inputs, dependent on erratic rainfall without complementary irrigation. Yields have doubled over the last 15 years and reached 2.7 tons per hectare according to the latest agricultural statistics, but are still far from the yield potential.

According to data from the International Food Policy Research Institute (IFPRI), wheat is preferred by wealthier, urban families, who consume 33 percent more wheat than rural households. Ethiopia needs to rethink its wheat price support system, which does not incentivize farmers and benefits mostly the wealthier, urban consumers. Wheat price support subsidies could, for instance, target bakeries located in poor neighborhoods.

Where to start to boost wheat productivity?

Ethiopia, especially in the highlands, has an optimum environment to grow wheat. But to make significant gains, the wheat sector needs to identify what limiting factors to address first. The Wheat initiative, led by Ethiopia’s Agricultural Transformation Agency (ATA), has targeted 2,000 progressive farmers across 41 woredas (districts) between 2013 and 2018, to promote the use of improved and recommended inputs and better cropping techniques within their communities. A recent IFPRI impact study showed a 14 percent yield increase, almost enough to substitute wheat imports if scaled up across the country. It is, however, far from the doubling of yields expected initially. The study shows that innovations like row planting were not widely adopted because of the additional labor required.

Hans Braun, WHEAT CGIAR research program and CIMMYT’s Global Wheat Program director, believes Ethiopian farmers can achieve self-sufficiency if they have the right seeds, the right agronomy and the right policy support.

One priority is to increase support for wheat improvement research to make wheat farmers more resilient to new diseases and climate shocks. Drought and heat tolerance, rust resistance and high yields even in low-fertility soils are some of the factors sought by wheat farmers.

International collaboration in durum wheat breeding is urgently needed as the area under durum wheat is declining in Ethiopia due to climate change, diseases and farmers switching to more productive and resilient bread wheat varieties. Braun advises that Ethiopia set up a shuttle breeding program with CIMMYT in Mexico, as Kenya did for bread wheat, to develop high-yielding and stress-resistant varieties. Such a shuttle breeding program between Ethiopia and Mexico would quickly benefit Ethiopian durum wheat farmers, aiming at raising their yields similar to those of Mexican farmers in the state of Sonora, who harvest more than 7 tons per hectare under irrigation. This would require a policy reform to facilitate the exchange of durum germplasm between Ethiopia and Mexico, as it is not possible at the moment.

Ethiopia also needs to be equipped to respond quickly to emerging pests and diseases. Five years ago, a new stem rust (TKTTF, also called Digalu race) damaged more than 20,000 hectares of wheat in Arsi and Bale, as Digalu — the popular variety used by local farmers — was sensitive to this new strain. The MARPLE portable rust testing lab, a fast and cost-effective rust surveillance system, is now helping Ethiopian plant health authorities quickly identify new rust strains and take preventive actions to stop new outbreaks.

Invest in soil health, mechanization and gender

In addition to better access to improved seeds and recommended inputs, better agronomic practices are needed. Scaling the use of irrigation would certainly increase wheat yields, but experts warn not to dismiss adequate agronomic research — knowing the optimal water needs of the crop for each agroecological zone — and the underlying drainage system. Otherwise, farmers are at risk of losing their soils forever due to an accumulation of salt.

‘’2.5 billion tons of topsoil are lost forever every year due to erosion. A long-term plan to address soil erosion and low soil fertility should be a priority,” highlights Marco Quinones, adviser at ATA. For instance, large-scale lime application can solve the important issue of acid soils, where wheat does not perform well. But it requires several years before the soil can be reclaimed and visible yield effects can be seen.

Mechanization could also boost Ethiopian wheat production and provide youth with new job opportunities. Recent research showed smallholder farmers can benefit from six promising two-wheel tractor (2WT) technologies. Identifying the right business models and setting up adapted training programs and financial support will help the establishment of viable machinery service providers across the country.

Better gender equity will also contribute significantly to Ethiopia becoming self-sufficient in wheat production. Women farmers, especially female-headed households, do not have the same access to trainings, credit, inputs or opportunities to experiment with new techniques or seed varieties because of gender norms. Gender transformative methodologies, like community conversations, can help identify collective ways to address such inequalities, which cost over one percent of GDP every year.

‘’With one third better seeds, one third good agronomy and one third good policies, Ethiopia will be able to be wheat self-sufficient,” concluded Braun. A National Wheat Taskforce led by EIAR will start implementing a roadmap in the coming days, with the first effects expected for the next planting season in early 2019.

The consultative workshop “Wheat Self-Sufficiency in Ethiopia: Challenges and Opportunities” took place in Addis Ababa, Ethiopia, on November 23, 2018.
