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

Written by Jérôme Bossuet on December 10, 2018. 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.

CIMMYT drought tolerant maize: A key innovation for millions of farmers, says FAO

Written by Jérôme Bossuet on December 3, 2018. Posted in Features.

As climate experts forecast another climate-warming El Nino in early 2019, maize varieties developed under the Drought Tolerant Maize for Africa (DTMA) initiative represent low-cost innovations that could improve the crop’s climate resilience and the livelihoods of millions family farmers across Africa, according to the UN Food and Agriculture Organization (FAO).

Drought tolerant (DT) maize was among 20 success stories featured at the Innovation Fair of the International Symposium on Agricultural Innovation for Family Farmers, organized and hosted by FAO in Rome from 21 to 23 November, 2018. Drawing more than 500 participants from farmer associations, international organizations, United Nations agencies, governments, research institutions and the private sector, the Fair aimed to devise and recommend actions that unlock the potential of agricultural innovation.

Drought-tolerant seeds: An affordable and effective way to cope with dry weather

‘’Since early 1990s, farmers in Zimbabwe face erratic rains and maize crops often fail due to frequent droughts,’’ said Cosmos Magorokosho, maize breeder based at the Harare, Zimbabwe, office of the International Maize and Wheat Improvement Center (CIMMYT).

Led by CIMMYT, funded by the Bill & Melinda Gates Foundation and the Howard Buffett Foundation, and involving 13 national maize breeding programs and various seed companies across Africa, DTMA is responsible for more than 160 new maize varieties, including 15 in Zimbabwe that yield 25 to 30 percent more than conventional varieties under dry conditions and perform as well as those varieties under normal rainfall. The latter was crucial for convincing seed companies to take up and market DT maize, according to Magorokosho.

In one study in drought-prone southern Zimbabwe, farmers using the DT varieties in dry years were able to harvest up to 600 kilograms more maize per hectare — worth $240 and enough maize for 9 months for an average family of 6 people — than farmers who sowed conventional varieties. The added food security comes at no additional cost and, if farmers choose to sell the grain, it brings extra income for other household needs.

Under the Stress Tolerant Maize for Africa initiative, CIMMYT and partners are continuing to develop maize varieties that cope not only with drought but with common constraints such as insect pests, diseases including Maize Lethal Necrosis and infertile soils.

Public-private partnerships enable demand-driven innovation

Adopting new technology or practices can represent unacceptable risks for resource-poor farming families, who live without the official safety nets enjoyed by peers in prosperous economies and will simply starve if their crops fail. Involving farmers, seed companies and other end users in development is essential for agricultural innovations to be widely adopted and sustainable, according to Bram Govaerts, global director of innovative business strategies at CIMMYT.

“Dialogue with global food processing companies can create market opportunities for smallholder farmers through approaches like local, responsible sourcing,’’ said Govaerts, speaking during the fair’s panel ‘Engaging the private sector to accelerate agricultural innovation.’

“More than 3,300 Mexican farmers on more than 35,000 hectares in 5 states will benefit from responsible sourcing arrangements, whereby the companies pay them to grow the grain using sustainable farming practices,” Govaerts explained, adding that the farmers will supply an estimated 400,000 tons of grain to participating companies in the next 3 to 5 years.

Mexico’s Agriculture Department (SAGARPA) supports these and other public-private partnerships through its investments in MasAgro, which studies, develops and transfers innovative farming practices and technologies to the field, with emphasis on family farmers.

In September, the FAO’s Regional Office for Latin America and the Caribbean acknowledged MasAgro as a replicable and scalable initiative that could contribute significantly to sustainable rural development in that region.

These two impactful examples show that agricultural innovation can only succeed through well-thought research and development partnerships, and building such collaborations is a science in itself.

Breaking Ground: Huihui Li links new genetic knowledge with crop breeding

Written by on November 28, 2018. Posted in Features.

Postcard_Huihui Li Breaking Ground

DNA is often referred to as the blueprint for life. It contains codes to make the proteins, molecules and cells essential for an organism’s growth and development. Over the last decade, scientists have been figuring out how specific sections of DNA in maize and wheat are associated with physical and genetic traits, such as grain size and drought resistance.

Quantitative geneticist Huihui Li with the International Maize and Wheat Improvement Center (CIMMYT) helps link this new genetic knowledge with traditional crop breeding, to speed up the development of improved maize and wheat varieties. Li’s research uses cutting-edge genomics, computational biology and statistical tools to turn data into useful information for plant breeders.

“Breeders always accumulate big amounts of data, most of the time they need efficient tools to mine the stories from this data. That’s part of our job in the Biometrics and Statistics Unit,” she explained.

Her research helps breeders more quickly and accurately predict which maize and wheat varieties in the CIMMYT gene bank have the traits they seek to create improved varieties. For example, if a plant breeder wanted to develop a hybrid maize variety with high protein levels and pest resistance, Li could help by identifying which parental varieties would have these traits.

It takes about ten years for crop breeders to develop a new hybrid. Removing some of the guesswork during the early stages of their experiments could reduce this time significantly. With increasing environmental pressures from climate change and population growth, releasing better crop varieties more quickly will be vital to ensure there is enough food in the future.

Li says her family and experience growing up in China greatly influenced her career choice.

“Through my grandfather’s experience as the head of the Bureau of Agriculture and Forestry, I learned that there were many people in China suffering from hunger, poverty and malnutrition,” she said.

Li realized that these issues were prevalent throughout the developing world when her mother left China for two years to serve as a foreign aid doctor in Cameroon.

“As a ten-year-old girl, I told myself that I should make my contribution to reduce hunger and poverty, and improve human nutrition in the future,” Li recalled. “I always ask myself, ‘What’s my value to humanity?”

She studied bio-mathematics and quantitative genetics at Beijing Normal University and Cornell University before joining CIMMYT in 2010 as a consultant.

“I wanted to join CIMMYT because it works throughout the developing world to improve livelihoods and foster more productive, sustainable maize and wheat farming,” Li explained. “Also, CIMMYT provided a platform where I could collaborate with scientists worldwide and receive academic and career-boosting trainings.”

She became staff in 2012 and is currently based out of the CIMMYT office in Beijing. In addition, Li is an adjunct associate professor with the Chinese Academy of Agricultural Sciences (CAAS). She helps CAAS scientists improve their experimental design and better incorporate genetic information into their crop breeding.

“I love doing research,” Li said. “I’m a curious person so if I can solve a problem, I feel very happy, but I really want my research to have value – not just for myself – but for the world.”

Huihui Li’s work contributes to Seeds of Discovery (SeeD), a multi-project initiative comprising: MasAgro Biodiversidad, a joint initiative of CIMMYT and the Mexican Ministry of Agriculture, Livestock, Rural Development, Fisheries and Food (SAGARPA) through the MasAgro (Sustainable Modernization of Traditional Agriculture) project and the CGIAR Research Programs on Maize (MAIZE) and Wheat (WHEAT).

Let’s make hunger history

Written by on November 22, 2018. Posted in Blogs.

KATHMANDU, Nepal — I feel humbled and honored to have been chosen for the 2018 MAIZE-Asia Youth Innovators Award. I want to thank my father and brother for never clipping my wings and letting me fly high. I want to thank my mother, who despite having no education, not being able to read or write a single word, dreamed of having a scientist daughter. Everyone has a story and this is mine.

Due to my family’s poverty and the hardships faced during the civil war in Nepal, I had to leave school at grade 5 and was compelled to work as child labor in a local hotel to meet my family’s daily needs. I remember those difficult months where I used to cry every day, as the hotel was right across from the school and I wanted to study so badly but I was deprived from education due to my family’s condition. My life changed when a mountain climber staying at the hotel heard my story and generously decided to pay my school fees. I would go on to graduate top of my class.

Everyone has challenges. It is my dream to dedicate my life to fight the greatest challenge of all: hunger.

The amount of undernourished people in the world has been increasing. According to the Food and Agriculture Organization of the United Nations (FAO), over 820 million people face chronic food deprivation. Many of these people live in developing countries, including my home country, Nepal. About 6 million people, which is about 23% of Nepal’s population, are undernourished. Moreover, half of children under the age of five suffer from malnutrition in Nepal.

Increasing agricultural production, gender equity and awareness is crucial to meet sustainable development goals by 2030. As an agricultural student, I chose to focus on maize-based systems, as maize is a staple food crop and a major component of feed and fodder for farm animals. It is the second major crop in Nepal after rice — first in the hill region of Nepal — and can be a backbone for food security and a good source of income for resource-poor farmers.

Demand for maize is growing in Nepal, but production has remained stagnant. This is partly due to lack of knowledge on proper nutrient management and fertilizer use. In addition, due to the economic situation in Nepal, many men have been forced to migrate to find work and support their families, which has led to an increased “feminization” of agriculture. However, female farmers frequently have less access to information and resources that would help them to increase yields.

Since my undergraduate degree, I have carried out research on nutrient management in maize in the Eastern Terai region of Nepal, particularly focusing on women, to increase the maize production and income of smallholder farmers. My research involved the use of Nutrient Expert, a dynamic nutrient management tool based on site-specific nutrient management principles, to increase maize production and enhance soil quality without negatively affecting the environment. Regional fertilizer recommendations are often too broad and cannot take into account the soil quality of individual farmers’ field, as it varies greatly among fields, seasons and years. Applying the incorrect amount of fertilizer is costly to farmers and can negatively affect the environment and crop yields.

The Nutrient Expert app rapidly provides farm-specific fertilizer recommendations for nitrogen, phosphorus and potassium for crops in the presence or absence of soil testing results, contributing to dynamic nutrient management, increased productivity and net returns from crops for farmers. In the meantime, it helps to decrease the nitrogen and phosphorous leaching from the soil into rivers, which protects the water ecosystem both in wetlands and oceans. This technology is sustainable because it optimizes the use of nutrients in the soil for higher productivity and prevents the overuse of fertilizer. It decreases the farmer’s cost of production and is environmentally friendly. Further, my research showed that Nutrient Expert helped farmers to produce 86.6% more maize grain than their previous fertilizer practice.

Proper nutrient management is just one of the challenges facing agriculture today. To address these challenges and to create a world without hunger it is extremely important to work with and include young people. Effective extension tools to train and motivate young minds in research and create more interest in maize-based systems and farming is necessary for the overall adoption and proper utilization of improved varieties and technologies.

Samjhana Khanal was recently awarded the 2018 MAIZE-Asia Youth Innovators Award from the CGIAR Research Program on Maize (MAIZE) in the category of “Change Agent” for her research on the productivity and profitability of hybrid maize in Eastern Terai, Nepal. Using Nutrient Expert, a decision support tool, individual maize farmers can get specific soil nutrition and fertilizer recommendations, resulting in higher grain yield, productivity and profits.

An agricultural graduate, Khanal has founded and co-founded several local social organizations in Nepal to involve young minds in the development of innovative strategies to work towards sustainable agriculture and zero hunger. Her organizations support more than 285 households with community microfinance, help resource-poor farmers and assist women farmers.

The MAIZE-Asia Youth Innovators Awards aim to celebrate youth participation in maize-based agri-food systems and are sponsored by the CGIAR Research Program on Maize (MAIZE) in collaboration with Young Professionals for Agricultural Development (YPARD).

CIMMYT laments the passing of Theodore Assimwe, Rwandan research pillar

Written by on November 15, 2018. Posted in News.

NAIROBI, Kenya (CIMMYT) — The CIMMYT family mourns the demise and honors the valuable contributions of Rwandan crop researcher Theodore Assimwe, who died on November 11, 2018.

An active and dedicated CIMMYT partner and one of eastern Africa’s most promising agricultural scientists, Assimwe was instrumental in Rwanda’s response to Maize Lethal Necrosis (MLN), coordinating pathogen surveillance and characterization and a key project for integrated management of the disease.

He was a pillar of the Rwanda Agriculture Board (RAB), with a well-recognized research track record in maize, cassava, and sweet potato. His capacity-building activities, together with those of CIMMYT, fostered the pursuit of advanced studies by numerous research colleagues.

His passion, commitment, and scientific rigor gained the respect of agricultural researchers, national plant protection organizations, and many other partners, including members of the global scientific community.

The CIMMYT community respectfully extends its sympathies and wishes for peace to the family of Assimwe.

International research-for-development coalition against fall armyworm, the not-so-nice, very hungry caterpillar

Written by Jérôme Bossuet on November 8, 2018. Posted in Features.

ADDIS ABABA, Ethiopia (CIMMYT) — African farmers have lost millions of dollars in earnings since 2016 due to the loss of crops to the voracious fall armyworm.

Since the initial shock, farmers, researchers, extension officers, agribusinesses, governments and donors have reacted quickly to fight the invasive pest in various ways, including with pesticides, agroecological approaches and new seeds.

Yet the situation is far from under control. A more coordinated research-for-development (R4D) action plan is urgently needed to ensure that effective and affordable solutions reach smallholder farmers in sub-Saharan Africa so they can sustainably combat the devastating pest.

Smallholder farm socioeconomics are highly complex, which makes adoption of any new technology or practice a challenge. “We must look at the big picture to design safer, accessible, effective and sustainable solutions against fall armyworm,” said Martin Kropff, director general of the International Maize and Wheat Improvement Center (CIMMYT), which jointly coordinated “Fall Armyworm Research for Development: Status and priorities for Africa,” an international conference held from Oct. 29 to 31 at the African Union Commission in Addis Ababa, Ethiopia.

Hosted by the Fall Armyworm R4D International Consortium, the conference was aimed at drawing a science-based roadmap to combat the hungry caterpillar. The partners organizing the conference were the African Union Commission (AUC), the Alliance for a Green Revolution in Africa (AGRA), the Centre for Agriculture and Biosciences International (CABI), CIMMYT, the Food and Agriculture Organization of the United Nations (FAO), the International Centre of Insect Physiology and Ecology (icipe), the International Institute of Tropical Agriculture (IITA), and the United States Agency for International Development (USAID).

Vulnerable smallholder farmers

African leaders consider the invasive fall armyworm “a big threat for African food security,” said Amira Elfadil, African Union Commissioner for Social Affairs, at the opening of the conference.

The caterpillar has munched through thousands of hectares of maize, sorghum and a few other commercial crops across Africa and is causing severe concerns among food and agriculture experts and policymakers. Since it was first detected in Nigeria and São Tomé, the moth has spread across more than 40 African countries and has been seen in India since July 2018. It could also invade Europe and other continents.

“Fall armyworm has been the fastest pest to expand across the continent,” said Eyasu Abraha, Ethiopia’s state minister for agriculture development.

The pest is a familiar foe to agricultural experts and farmers in the Americas who have fought against it for several decades. However, the pest has found an ideal environment to flourish in Africa, with diverse agro-ecologies and a warmer climate all year round amplifying its persistent threat.

It has a host range of more than 80 plant species, including maize, a staple food on which millions of people throughout sub-Saharan Africa depend for food and income security. It can cause total crop losses, and at advanced larval development stages can be difficult to control even with synthetic pesticides. The female fall armyworm can lay up to a thousand eggs at a time and produce multiple generations very quickly without pause in tropical environments. The moth can fly 100 km (62 miles) a night, and some moth populations have even been reported to fly distances of up to 1,600 kilometers in 30 hours, according to experts.

Entomologists are trying to fill a knowledge gap on how the fall armyworm behaves and migrates throughout Africa.

Solutions that may work to combat the pest in Brazil or North America may not be applicable for the agricultural context in Africa where most farmers are low-resource smallholders, struggling to access new knowledge and technologies.

High cost of ineffective collaboration

Hans Dreyer, director of FAO’s plant protection division, listed many collaborative initiatives, including national task forces and expert working groups, which contributed to document and inform the current state of knowledge.

There are still many knowledge and technical gaps. Some resourceful information platforms are already available for the farmers and extension workers, including the fall armyworm web portal created by CABI, the mobile farmer Q&A service PlantVillage, or Precision Agriculture for Development’s text messaging advisory service MoA-Info.

“The cost of not collaborating is pretty severe,” said Regina Eddy, who leads the Fall Armyworm Task Force at the USAID Bureau for Food Security. The real gamechanger will be that “all experts in the room agree on a common and concrete research-for-development agenda and how to organize ourselves to implement it effectively,” she added.

During the conference, the experts debated intensely on the technical gaps and the best ways to combat the pest through an integrated pest management strategy, including how to scout the caterpillar in the crop field, establish monitoring and surveillance systems, pest control innovations and appropriate policy support to accelerate introduction of relevant innovations.

Safe, sustainable, farmer-centered solutions

Short-term responses to the pest at present include synthetic pesticide use. However, there are public health and environment concerns over some of the toxic pesticides being used in Africa to control the fall armyworm.

Brian Sobel from Catholic Relief Services recalled witnessing a woman in Malawi who, in an effort to combat the pest, sprayed much more chemical pesticide on her maize than necessary.

The rapid increase of the pesticide market in Africa has led to the circulation of plenty of banned or counterfeit products, some very toxic for the farmer, said Steven Haggblade, a professor in the Department of Agricultural, Food and Resource Economics at Michigan State University in the United States. Farmers are often not well trained in the use of such chemicals and do not protect themselves during application, he said.

Pesticide use has many negative trade-offs, said Paul Jepson, a professor of environmental and molecular toxicology in the College of Agricultural Sciences at Oregon State University. Natural enemies like parasitic wasps are also often far more vulnerable to pesticides than fall armyworm larvae, which are hard to reach and hide themselves in the maize whorls for instance.

Continental action plan

A key recommendation made by the Fall Armyworm R4D International Consortium is to develop common methodologies and research protocols to ensure data from various studies across the continent are better used and compared. For example, how best could the true impacts of the fall armyworm on food and seed security, public health and environment be measured? Collaborative research could include multilocation assessment of the relationship between observed crop damages and yield losses, which is key to determine the efficacy of a pest control innovation.

Conference participants also agreed to work on defining economic and action thresholds for fall armyworm interventions, to ensure better recommendations to the farming communities.

Because no one solution can fit all farmers and socioeconomic contexts, advice must include use of environmentally safer pesticides, low-cost agronomic practices and landscape management and fall armyworm-resistant varieties, among other integrated pest management tools.

Enhanced cooperation between countries to access new technologies and manage the transboundary pest is seen as a priority. Consortium experts also urge an integrated pest management approach, initiated based on farmers’ needs. Controlling the fall armyworm in the long run will require important investments into research-for-development for generating and sharing knowledge and addressing technical gaps with farmers.

New initiative to improve access to high quality maize seed for African farmers

Written by on October 26, 2018. Posted in Press releases.

Research partners to develop new maize hybrid seed production system to help smallholder farmers access modern, high quality maize hybrid seed.

Pretoria, South Africa, 26 October 2018 – An initiative launched in 2016 seeks to provide African smallholder farmers with better quality and high yielding hybrid maize seed. The Seed Production Technology for Africa (SPTA) initiative strives to improve seed production systems to ensure that high-quality hybrid maize seed is available to smallholder farmers, as well as to deliver new hybrids with a high yield potential adapted for low fertility areas common in sub-Saharan Africa (SSA).

SPTA will utilize a technology provided by Corteva Agriscience, and implemented by the Agricultural Research Council of South Africa (ARC) alongside the International Maize and Wheat Improvement Center (CIMMYT), and the Kenya Agricultural and Livestock Research Organization (KALRO). Funded by the Bill & Melinda Gates Foundation, the four-year initiative will cost US$ 6.4 million.

“As Africa faces significant challenges of low maize yields, climatic extremes and variability, costly farm inputs, threats due to pests and diseases, and growing demand for food, it is critical to provide smallholder farmers with access to high quality and stress resilient modern maize hybrids to allow them to increase yields and incomes,” said Kingstone Mashingaidze, Senior Research Manager at ARC.

The SPTA process will address pressing seed production concerns in the region that include insufficient genetic purity due to pollen contamination resulting from improper or incomplete detasseling practices. As a result, small and medium seed companies are expected to produce greater volume of hybrid maize seed at lower cost. Partner seed companies in the region will access the technology royalty free.

Maize productivity in Africa lags behind other maize producing regions, and through SPTA more smallholders will improve their yield. Average maize yield in much of Africa is approximately 2 metric tons per hectare, which is less than 20 percent of the yield level in more productive parts of the world. Farmers cannot access or afford high quality seed. Only 57 percent of the SSA maize growing area is planted with recently purchased seed; a lot of hybrids grown in the region are obsolete – 15 years or older compared to an average of less than 5 years in highly productive regions. In many situations, seeds of these older varieties are no longer suited for the climate and cropping environments that exist today.

Hybrid maize seed delivered through SPTA will have higher yield in low fertility environments. This will enable resource-constrained farmers to harvest more despite limited inputs like fertilizer. This means stronger livelihoods coupled with improved professionalism in the maize seed value chain for farmers, seed companies, consumers, and governments to deliver a more food-secure future.

SPTA originated from the Improved Maize for African Soils (IMAS) project that concluded in 2015. IMAS focused on developing maize hybrids that could use nitrogen fertilizer more efficiently to deliver higher yields under low fertility conditions prevalent in Africa. The IMAS project was funded by the Bill & Melinda Gates Foundation together with the United States Agency for International Development.

To feed the world, take the science to the farmer

DES MOINES (Iowa) — Hundreds of food and agriculture leaders from around the world gathered last week in Iowa, USA, for the 2018 edition of the Borlaug Dialogue. Much of the conversation this year was centered on how to “take it to the farmer,” as Norman Borlaug famously said. Experts discussed how to build sustainable seed systems, grounded on solid science, so improved varieties reach smallholder farmers.

Louise Sperling, senior technical advisor at Catholic Relief Services, presented a study on the sources of seed for smallholder farmers in Africa. She explained that 52.2 percent of households receive new varieties, but only 2.8 percent of the seed comes through agro-dealers. The biggest source is local markets and own stock, the so-called informal channels.

Quality and variety of seed should be the focus, emphasized Jean Claude Rubyogo, seed systems specialist at CIAT. In his view, we need to integrate formal and informal seed distribution channels, using the competitive advantages of each.

“When we take good seed, we address all African soil,” said Ruth Oniang’o, board chair at the Sasakawa Africa Foundation. Oniang’o explained access to financing is a major hurdle for smallholders to access better seed and other innovations. In her view, current financial products are inadequate. “Why should we get a farmer to pay 20 percent interest rates on a small loan?”

B.J. Marttin, member of the managing board of Rabobank Group, recommended financial institutions to partner with farmers through every stage, from production to sale, so they better understand risk and the whole value chain. Simon Winter, executive director of the Syngenta Foundation for Sustainable Agriculture, captured the main points from the session on financing for agricultural entrepreneurs. “We have to have the farmer at the center. The farmer is the ultimate customer,” Winter said. “If we are not serving farmer needs, we are not really solving the problems.”

Research to feed the world

The 2018 Global Agricultural Productivity (GAP) Report, presented at the Borlaug Dialogue, shows the growing gap between future food supply needs and agricultural production, particularly in low-income countries. To meet the projected food needs of nearly 10 billion people in 2050, global agricultural productivity must increase by 1.75 percent annually, the report states, but has only increased 1.51 percent annually since 2010.

A plenary session led by CGIAR explored the role of research in tackling this and other complex challenges. “We have to talk about food and agriculture research,” said former U.S. Secretary of Agriculture Dan Glickman. People need to understand research is not abstract academic knowledge, but rather useful innovation that goes “from the farm, to the table and to the stomach,” he explained.

“Innovation, no matter where you are in the world, is key to moving forward,” said Patience Koku, a farmer from Nigeria part of the Global Farmer Network. “I don’t think the farmers in Africa or in Nigeria need a lot of convincing” to adopt innovation, Koku noted. If someone is able to explain what a new technology can do, “farmers see that science can make their life better and embrace it.”

Rising to the challenge

Agricultural research is also crucial to confront global threats like pests, conflict and climate change.

Two separate sessions, hosted by Corteva Agriscience and CIMMYT, shared the latest approaches in the fight against fall armyworm and other pests and diseases. The Director General of the International Maize and Wheat Improvement Center (CIMMYT), Martin Kropff, explained how organizations are working together to respond to the rapid spread of fall armyworm in Africa and Asia. “We have to solve the problem based on science, and then develop, validate and deploy integrated pest management approaches,” Kropff said.

As part of the World Food Prize outreach program, Bram Govaerts, director of innovative business strategies at CIMMYT, gave a lecture to students at Brody Middle School about the importance of agriculture and food. “When people can’t grow crops or pay for food to feed their families, desperation turns to conflict.”

At a side event, the Economist Intelligence Unit presented the Global Food Security Index 2018, which ranks food systems in 113 countries based on affordability, availability, and quality and safety. Senior consultant Robert Powell explained that the index now includes an adjustment factor based on each country’s natural resource risks and resilience to the impacts of a changing climate. “All countries will experience the impact of climate change,” Powell said.

The pernicious effects of climate change were also evident to the 2018 World Food Prize winners, David Nabarro and Lawrence Haddad, who have led global efforts to curb child malnutrition. “There is no evidence to me that [this] crisis is going to stop, because climate change is here,” Nabarro declared. “The foods we choose to grow and eat have a large impact on emissions,” Haddad said. “Food has a lot to offer” on climate mitigation and “diversity is the secret sauce” for climate adaptation. “We need food systems that are diverse: in crops, locations, organizations involved in them…”

Less biodiversity translates into “less resilience and worse nutrition,” according to the Vice President of Peru, Mercedes Aráoz. Through improved health and nutrition services, the country more than halved malnutrition among children under five, from 28 percent in 2008 to 13.1 percent in 2016.

A rallying cry for nutrition

The impact of nutrition on the first 1,000 days of life lasts a lifetime, explained Haddad. “For young kids, these are permanent shocks.”

“If a person is not nourished in those very important weeks and months of life, the long-term consequences are likely to be irreversible,” Nabarro added. According to him, nutrition needs to be the target in the 2030 agenda, not only hunger.

“Nutrition-based interventions present us a new lens through which to create and assess impact as agricultural researchers,” said Elwyn Grainger-Jones, the executive director of the CGIAR System Organization. “Our future success must come not only from ensuring an adequate supply of calories for the global population, but also the right quality and diversity of foods to tackle hidden hunger as well.”

“We are not going to resolve the challenges of undernutrition without the ag sector stepping up in a big way and differently,” argued Shawn Baker, director of nutrition at the Bill & Melinda Gates Foundation. “Nutrition needs you,” Baker told other participants. “Welcome to the nutrition family.”

Fall armyworm on the agenda at the 2018 Borlaug Dialogue

Written by Rodrigo Ordóñez on October 25, 2018. Posted in News.

DES MOINES (Iowa) — At the plenary of the 2018 Borlaug Dialogue, a global panel of experts gave an overview of the origins of the fall armyworm, how it is spreading around the world, and how governments, farmers and researchers are fighting against this pest.

Pedro Sanchez, research professor in tropical soils at the University of Florida and 2002 World Food Prize Laureate, shared background information on the history of the fall armyworm and the early attempts to neutralize it, decades ago. He pointed out that once-resistant varieties were eventually affected by this pest.

The Director General of the International Maize and Wheat Improvement Center (CIMMYT), Martin Kropff, shared the most recent developments and explained how organizations are working together to respond to this pest. “We want to have science-based, evidence-based solutions,” Kropff said. “We have to solve the problem based on science, and then to develop and validate and deploy integrated pest management technologies.”

The director general of the Ethiopian Institute of Agriculture, Mandefro Nigussie, reminded that in addition to affecting people and the environment, fall armyworm “is also affecting the future generation,” as children were pulled out of school to pick larvae.

The response against fall armyworm cannot be done by governments alone, panelists agreed. It requires the support of multiple actors: financing the research, producing research, promoting the results of the research and implementing appropriate measures.

Rob Bertram, chief scientist at USAID’s Bureau for Food Security predicted the fall armyworm will continue to be a “serious problem” as it moves and migrates.

The director general and CEO of the Kenya Agricultural & Livestock Research Organization, Eluid Kireger, emphasized the importance of global collaboration. “We need to borrow the technologies that are already working”.

The fall armyworm was also discussed during the Corteva Agriscience Forum side event, on a session on “Crop security for food security”. The Director of CIMMYT’s Global Maize Program and the CGIAR Research Program on Maize, B.M. Prasanna, was optimistic about the efforts to tackle this voracious pest. “I’m 100 percent confident that the pest will be overcome, but it requires very solid synergistic and coordinated actions at the national level, at the regional level and at the continental level.”

CIMMYT is co-leading the Fall Armyworm R4D International Consortium. “Fall armyworm is not going to be the only threat now and forever; there will be more insects, pests and pathogens moving around,” Prasanna said. “Global connectedness is exacerbating this kind of problem, but the solution lies also in global connectedness.”

Reflections on the global impact of biofortification

Written by Carolyn Cowan on October 19, 2018. Posted in News.

Over two billion people across the world suffer from hidden hunger, the consumption of a sufficient number of calories, but still lacking essential nutrients such as vitamin A, iron or zinc. This can lead to severe health damage, blindness, or even death, particularly among children under the age of five. Furthermore, a recent FAO report estimates the number of undernourished people worldwide at over 800 million, with severe food insecurity and undernourishment increasing in almost all sub-regions of Africa, as well as across South America.

In recognition of World Food Day and the focus of the 2018 World Food Prize on nutrition, the CGIAR Research Centers and Programs reflect on the significance and global impact of biofortification and climate resilient crops – key components in achieving Sustainable Development Goals 2: Zero Hunger and 3: Good Health and Wellbeing by 2030.

As biofortification work nears a quarter-century – 10 years in the making, and another 15 years of implementation – the CGIAR evaluates what has made it such a success, in How the science of biofortification grew from an idea to a food revolution.

Biofortification enables scientists to fortify staple crops with micronutrients to address hidden hunger. There are now 290 new varieties of 12 biofortified crops – including maize, wheat and potatoes – being grown in 60 countries, reaching an estimated 10 million farming households.

The first biofortified maize variety was quality protein maize (QPM), developed by International Maize and Wheat Improvement Center (CIMMYT) scientists Evangelina Villegas and Surinder Vasal. QPM features enhanced levels of lysine and tryptophan, essential amino acids, which can help reduce malnutrition in children. Villegas and Vasal would later go on to win the World Food Prize in 2000 for this groundbreaking work, and genetic variation found in QPM would serve as the baseline for developing further biofortified products, such as zinc-enriched maize and vitamin A orange maize.

Several key factors have contributed to the success of biofortification. One is partnership. The CGIAR Centers work with hundreds of partners around the world, from national governments and research institutes through to non-governmental organizations and farmers on the ground. Other factors include the ability to build evidence and conduct thorough monitoring and evaluation, the maintenance of a clear vision on how research will have impact, and coordinated investment.

In considering the future role of biofortification in our evolving agricultural landscape, the article highlights the need to tie up with meeting global goals on sustainable development in terms of food security and improved nutrition, and the importance of ‘future proofing’ new varieties in the face of climate change.

In further support of biofortification, the UK’s Department for International Development (DFID) recognized the importance of CGIAR’s world-renowned agricultural research in the fight to end global hunger. Support from DFID has been crucial to biofortification work in Africa as well as in the development of drought-tolerant maize by CIMMYT and the CGIAR Research Program on Maize (MAIZE), which has increased farmers’ yields by up to 30 per cent, benefitting 20 million people in 13 African countries. Over 300 drought tolerant maize varieties were released by CIMMYT under the Drought Tolerant Maize for Africa (DTMA) project, which ran from 2006 to 2015, and continue to be scaled out and provide benefits to smallholder farmers in the region today. DFID also highlighted the impact of their support to CIMMYT and the CGIAR Research Program on Wheat (WHEAT) in the development of disease resistant wheat varieties that help avoid food shortages and exacerbated hunger worldwide.

After a prolonged decline in global hunger, findings pointing to a recent increase are alarming. Coupled with uncertainties surrounding food supply due to challenges like changing climates and ever-present crop pests and diseases, the challenges we face are significant. The development and deployment of crops biofortified with nourishing micronutrients and equipped to cope with abiotic and biotic stresses is of fundamental importance. The work of the CGIAR Centers and Research Programs is vital to improve the livelihoods of smallholder farmers and to fuel the fight towards zero hunger by 2030.

Better together: Partnership around zinc maize improves nutrition in Guatemala

Written by Jennifer Johnson on October 16, 2018. Posted in Features.

On World Food Day, October 16, the International Maize and Wheat Improvement Center (CIMMYT) joins the Food and Agriculture Organization of the United Nations and partners around the world in their call to realize Sustainable Development Goal 2: Zero Hunger by 2030. Learn how CIMMYT, HarvestPlus and Semilla Nueva are working together to use biofortified zinc-enriched maize to reduce malnutrition in Guatemala, an important component of Goal 2.

Over 46 percent of children under five in Guatemala suffer from chronic malnutrition. More than 40 percent of the country’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, HarvestPlus and Semilla Nueva are working together to change this, through the development and deployment of the world’s first biofortified zinc-enriched maize.

“In Latin America, Guatemala is among the top 3 countries with the highest rates of zinc and iron deficiencies, and it is characterized by a high production and consumption of staple foods such as maize and beans. This made Guatemala, along with Haiti, the top prioritized countries for biofortification in the region, according to the Biofortification Priority Index (BPI) for Latin America,” said Salomón Pérez, the HarvestPlus country coordinator for Guatemala. HarvestPlus developed the BPI in 2013 to select the countries, crops and micronutrients in which to focus their efforts in Latin America. The BPI combines three sub-indexes: production, consumption and micronutrient deficiency level. “As maize is a staple food in Guatemala, with high levels of consumption and production, the development of biofortified maize with enhanced zinc was prioritized for the country,” he said.

Biofortified maize is a unique and efficient way of improving nutrition. As the nutrients occur naturally in the plant, consumers do not have to make any behavioral changes to get results. Rather than having to import supplements or fortify food, seeds and crops are sourced within the country, which makes this option more sustainable and accessible even in remote rural areas. It tastes the same as non-biofortified maize varieties and requires no special preparation methods. This made biofortification the obvious choice for improving zinc deficiency in Guatemala, and CIMMYT the obvious partner.

“CIMMYT has over 50 years of experience in tropical maize breeding for different traits,” said Félix San Vicente, one of the CIMMYT maize breeders leading the project. “Throughout our history we have developed elite materials with important agronomic and nutritional traits, such as Quality Protein Maize (QPM).”

The long lineage of zinc maize

Developed by CIMMYT scientists Evangelina Villegas and Surinder Vasal, QPM has enhanced levels of lysine and tryptophan, essential amino acids, which can help reduce malnutrition in children. Villegas and Vasal would later go on to win the World Food Prize in 2000 for this groundbreaking work, and genetic variation found in QPM would serve as the baseline for developing zinc-enriched maize.

After years of breeding work and research, the world’s first biofortified zinc maize hybrid, ICTA HB-18, was released in Guatemala in May 2018. It was developed by CIMMYT, the CGIAR Research Programs on Maize (MAIZE) and Agriculture for Nutrition and Health (A4NH), and Guatemala’s Institute for Agricultural Science and Technology (ICTA) with support from HarvestPlus. Commercialized by Semilla Nueva under the name Fortaleza F3, the biofortified zinc maize hybrid contains 6-12ppm more zinc and 2.5 times more quality protein compared to conventional maize varieties. An open pollinated variety, ICTA B-15, was also released.

Just 100 grams of tortilla made of either of these varieties can provide 2.5 milligrams of zinc, 50 percent of the daily recommended intake for children, making zinc-enriched biofortified maize an excellent tool in the fight against malnutrition and hidden hunger.

As CIMMYT is a breeding organization, it depends on national partners to get seeds to the farmers. That is where Semilla Nueva comes in. This non-profit social enterprise is working to get high yielding biofortified seeds to farmers in Guatemala.

The last mile

“We need to be able to impact farmers with our improved germplasm,” said San Vicente. “Semilla Nueva takes us to the last mile, to the farmers, which alone we could not do, so that our breeding work can achieve impact in farmers’ fields and lives.”

Semilla Nueva targets commercial farmers in Guatemala, as they are the main source of maize consumed in the country. Typically, a quarter of their harvest is consumed at home and surplus is sold in local markets, meaning that the zinc maize not only provides increased income to farmers, but also improves nutrition in their families, communities and country at large.

“CIMMYT, along with partners like HarvestPlus, have provided the technologies and support to allow us to come up with new ways to improve farmers’ lives. Tapping into decades of research from qualified scientists is the only way that an organization of our size can have hope of making an impact in the lives of millions of farmers. That’s what makes the partnership so incredible,” said Curt Bowen, executive director and cofounder of Semilla Nueva. “We provide the innovative way to get technologies to farmers through our social enterprise model. CIMMYT and HarvestPlus come up with the technologies that we never could have come up with on our own. Together, we help thousands of families make huge changes in their lives and take on malnutrition, which is one of the world’s biggest challenges to ending global poverty.”

Semilla Nueva plans to produce 5,000 bags of Fortaleza F3 next year, which will represent 5 percent of the Guatemalan hybrid seed market.

“Farmers have responded very positively to Fortaleza F3. They are convinced of its performance, especially during the dry season,” said Angela Bastidas, senior operations director at Semilla Nueva. “The way we approach farmers is not different than other seed companies; through farm visits, meetings, or field days. We are not reinventing the wheel. The difference with us has been offering farmers exactly what they need in terms of maize performance and price. Additionally, they find that our maize produces soft tortillas that taste better!” she explained.

In the end, the results speak for themselves. Fortaleza F3 increases yields by 13 percent and profits by $164 per bag compared to other mid-priced seeds, which goes a long way in improving farming families’ livelihoods, food security and nutrition.

“With Fortaleza F3, I pay less for the seed compared to other mid-priced competitors that I used to plant. F3 also yields more, giving me a greater profit,” said Rómulo González, a farmer from the southern coast of Guatemala. “With the extra income I’ve gotten since switching to F3, I’ve been paying for my daughter to go to school. Fortaleza F3 not only gave me a good harvest, but also the ability to support my daughter’s education.”

Natalia Palacios, CIMMYT maize quality specialist, spearheads the center's work to raise the nutritional value of maize-based foods.

CIMMYT has key role to address global nutrition challenges, says maize quality specialist

Written by Emma Orchardson on October 15, 2018. Posted in News.

Exposure to more frequent and intense climate extremes is threatening to reverse progress towards ending hunger and malnutrition. New evidence points to rising world hunger. A recent FAO report estimated the number of undernourished people worldwide at over 800 million. Severe food insecurity and undernourishment are increasing in almost all sub-regions of Africa, as well as across South America.

“It’s very important to ensure food security,” says CIMMYT maize quality specialist Natalia Palacios. “But we also have to focus on food nutrition, because increasing yields doesn’t always mean that we’re improving food quality.” Food quality, she explained, is affected not only by genetics, but also by crop and postharvest management practices. As head of CIMMYT’s maize nutritional quality laboratory, Palacios’ work combines research on all three.

As she prepares to attend the World Food Prize in Des Moines, Iowa – which this year recognizes the contributions of those working to combat malnutrition and ensure food and nutrition security – Palacios discusses ways in which she and CIMMYT colleagues work to address health and nutrition challenges.

What role can CIMMYT play in addressing global nutrition challenges?

Nutrition is an interdisciplinary issue, so there are several ways for CIMMYT to engage. In breeding, there’s a lot we can do in biofortification—which means to increase grain nutrient content. The CIMMYT germplasm bank, with its more than 175,000 unique collections of maize and wheat seed, is an invaluable source of genetic traits to develop new nutritious and competitive crops.

CIMMYT also addresses household nutrition challenges, including food availability, proper storage, and consumer behavior and choice. In cropping systems, the Center studies and promotes diversification, agroforestry, and improved soil health and farming practices, and at the landscape level it examines the role of agricultural practices. Gender research and foresight allow us to identify our role in the evolving setting of agri-food systems and rural transformation. We are prioritizing areas where CIMMYT can play a key role to address global nutrition challenges and partner effectively with leading nutrition groups worldwide.

How does the biofortification of staple crops like maize and wheat help to improve nutrition?

CIMMYT biofortification research has focused on micronutrients such as provitamin A in maize and zinc in both maize and wheat, to benefit consumers whose diets depend on those crops and may lack diversity. Biofortification must be complemented by enhanced dietary diversification and education for better nutrition.

How important are processing and post-harvest storage in terms of ensuring high-nutritional quality?

Research on post-harvest processing and storage is key to our work. A critical topic in maize is monitoring, understanding, and controlling aflatoxins—poisonous toxins produced by molds on the grain. CIMMYT has worked mainly to develop aflatoxin-tolerant maize, but recent funding from the Mexican food industry has enabled us to launch a small, more broadly-focused study.

In the past, aflatoxins showed up every three or four years in Mexico, and even then at fairly low levels. Aflatoxin incidence has lately become more frequent, appearing almost every year or two, as climate changes expose crops to higher temperatures and fungi are more likely to develop in the field or storage, especially when storage conditions are poor.

What are the implications of high aflatoxin incidence for health and nutrition?

The implications for health and nutrition are huge. High consumption can affect the immune system and lead to pancreatic and liver cancers, among other grave illnesses.

How easy is it to tell if a kernel is contaminated?

It’s impossible to tell whether grain is contaminated without doing tests. The chemical structure of the toxin includes a lactone ring that fluoresces under UV-light, but this method only tells you whether or not the toxin is present, and results depend contamination levels and kernel placement under the lamp.

We’re spreading the lamp method among farmers so they can detect contamination in their crops, as well as making other of our other methods more accessible and less expensive, for use by farmers and food processors.
