Breaking Ground: Dagne Wegary at a busy intersection on the maize value chain

Written by Mike Listman on . Posted in Features.

TwitterBGDagneLike many scientists at the International Maize and Wheat Improvement Center (CIMMYT) who grew up in smallholder farm households, Dagne Wegary draws inspiration from recollections of adversity and has found in science a way to make things better.

“I saw how my community struggled with traditional crop and livestock husbandry and, at an early age, started to wonder if there was a science or technology that might ease those hurdles,” Wegary said, referring to his childhood in a village in Wollega, a western Ethiopian province bordering South Sudan.

“I chose to study and work in agriculture,” Wegary explains. “Even though the farming system in my home village has not changed significantly, I am happy that the community is now among Ethiopia’s top maize producers and users of improved seed and other agricultural inputs.”

As a maize seed system specialist, Wegary works at the nexus between breeding science and actual delivery of improved seed to farmers. He interacts regularly with diverse experts, including CIMMYT and Ethiopia’s breeders and members of the national ministries of agriculture, the Ethiopia Agricultural Transformation Agency (ATA), non-governmental organizations including Sasakawa Global-2000 and World Vision, and especially public, private or community-based seed producers.

Quality seed is farmers’ principal means to improve productivity and secure food, according to Wegary, who calls it “the carrier of complementary production technologies, which in combination with improved agronomy can significantly increase crop yields.”

“I am most happy with Ethiopia’s increased maize productivity and self-sufficiency, which is due partly to the use of improved technologies to which we all contribute,” he said, noting that maize grain yields in Ethiopia had more than doubled since the 1990s, reaching 3.7 tons per hectare in 2016, a level second only to that of South Africa, in sub-Saharan Africa.

According to Wegary, these improvements are the result of strong government support for maize research and development, along with the strong partnership between CIMMYT and the national program that has led to the release of high-yielding, stress tolerant and nutritionally-enriched maize varieties. He said that farmers’ have also increased their use of improved technologies and that public, private and community-based companies now market seed.

“Supplying seed used to be highly-centralized, but farmers’ main sources of seed now are cooperatives that buy from seed companies or companies that market directly to farmers” Wegary explained. “Many companies have their own stockists and dealers who directly interact with farmers.”

Before joining CIMMYT, as a scientist with the Ethiopian Institute of Agricultural Research (EIAR), Wegary helped to implement a number of CIMMYT-led projects. “These allowed me to know CIMMYT very well and sparked my interest in joining the Center and working with its high-caliber and exemplary scientists.”

A plant breeder by training with a doctoral degree in breeding from the University of the Free State, South Africa, soon after joining CIMMYT Wegary began to contribute to projects to develop and disseminate seed of improved maize varieties with high levels of drought tolerance and enhanced protein quality.

He has been involved since the early 2000s in promoting quality protein maize (QPM). The grain of QPM features enhanced levels of lysine and tryptophan, amino acids that are essential for humans and certain farm animals. Wegary took part in a CIMMYT project that supported the release of five new QPM varieties.

“Many companies are now producing and marketing QPM in Ethiopia,” Wegary said. A 2009 study in the science journal Food Policy found that eating QPM instead of conventional maize resulted in 12 and 9 percent increases in growth rates for weight and height, respectively, in infants and young children with mild-to-moderate undernutrition and where maize constituted the major staple food.

Wegary believes sub-Saharan Africa’s biggest challenges include climate change-induced heat and drought, natural resource depletion, and pest and disease outbreaks, coupled with increasing populations. In combination these factors are significantly reducing food security and the availability of resources.

“I want to be a key player in the battle towards the realization of food and nutritional security, as well as the economic well-being of poor farmers, through sustainable and more productive maize farming systems.”

EL BATAN, Mexico (CIMMYT) – Maize nutritionally enhanced with vitamin A can bring significant health benefits to deficient populations, but recent modeling studies in Zambia suggest that its impact is being cut short by the low retention of provitamin A carotenoids – a naturally occurring plant pigment also found in many orange foods that the body then converts into vitamin A – during storage and postharvest grain loss.

Up to 30 percent of grain is lost in African countries when maize is stored using common storage methods, such as artisanal silos or woven bags, due mostly to insect, rodent or fungi infestations and accumulation of poisonous chemical compounds called mycotoxins, which are produced by certain fungi.

A recent study evaluated the impact of carotenoid retention in orange maize using different storage methods to assess the most efficient way to store grain without losing vitamin A carotenoids.  The researchers specifically evaluated how hammer and breakfast meal – the two most widely consumed grains in Zambia – age in metal silos, multilayer polyethylene and common woven bags, as well as single and multilayer polyethylene bags.

The researchers found significant differences between grain storage methods after 6 months of storage. Across all methods, hammer meal retained more carotenoid than breakfast meal after 4 months, though there was no difference in provitamin A carotenoid loss when using single and multilayer polyethylene bags.

Potential contribution of stored orange maize to the estimated average provitamin A requirement of children and women was around 25 percent – 26.5 and 24.3 percent for children and women, respectively – suggesting that orange maize meal can provide significant amounts of provitamin A to Zambian diets, even after 4 months of storage.

HARARE, Zimbabwe (CIMMYT) – More farmers in Zimbabwe are demanding high-yielding, highly nutritious and drought tolerant provitamin A maize.

In Zimbabwe, nearly one in every five children under the age of five years are vitamin A deficient. These deficiencies can lead to lower IQ, stunting and blindness in children, and increased susceptibility to disease across all ages.  While vitamin A is available from a variety of sources, such as fruit, green leafy vegetables and animal products, these are often too expensive or unavailable to the more than 10 million people living in Zimbabwe’s rural areas.

Zimbabwe’s ZS242 – an orange provitamin A maize variety released on the market by the government in October 2015 – is particularly popular with farmers due to its nice aroma and good taste.  Consuming foods made from orange maize, which is rich in beta-carotene, can provide maize-dependent populations with up to half their daily vitamin A needs, according to HarvestPlus.

Orange vitamin A maize has been conventionally bred to provide higher levels of provitamin A carotenoids, a naturally occurring plant pigment also found in many orange foods such as mangoes, carrots and pumpkins, that the body then converts into vitamin A.

These varieties are also high-yielding, disease resistant and drought tolerant, presenting an opportunity for farmers to not only increase yields but also enhance the availability of vitamins and minerals for people whose diets are dominated by micronutrient-poor staple food crops.

Mary Sikirwayi, a farmer from Murewa District, Zimbabwe, bought provitamin orange maize seed during a seed fair organized by the International Maize and Wheat Improvement Center (CIMMYT), in collaboration with the Technical Centre for Agricultural and Rural Cooperation.

The maize grew and matured so fast that by the time her family wanted to try the fresh cobs for cooking and roasting, they had already started to dry. After harvesting the grain, she decided to make sadza, a porridge-like staple food consumed in Zimbabwe. When her family ate the sadza, everyone was so excited about the good taste and flavor of the food.

In addition to the good taste of the sadza from the provitamin A maize, Sikirwayi said the yield from the orange maize is more than five times higher than the national maize average yield. In the coming year, she plans to double the planted area of orange maize, due to its high demand both on the market and in her household.

CIMMYT and HarvestPlus have been working with Zimbabwe’s Department of Research and Specialist Services, Ministry of Health and Child Care, universities, seed companies, processors, retailers and the Food and Agriculture Organization of the United Nations, to demonstrate the benefits of orange maize since 2012. The Zimbabwe government has expressed strong support for enriching the micronutrient content of plants and other crops, including maize.

Breaking Ground: Mainassara Zaman-Allah uses remote sensing to expedite phenotyping

Written by on . Posted in Features.

TwitterBGMZMEXICO CITY (CIMMYT) – Remote sensing technology is on track to make crop breeding faster and more efficient, ensuring smallholder farmers get the improved maize varieties they need.

Field phenotyping – the comprehensive physical assessment of plants for desired traits – is an integral part of the crop breeding process but can create a costly and time-consuming bottleneck, according to Mainassara Zaman-Allah, abiotic stress phenotyping specialist at the International Maize and Wheat Improvement Center (CIMMYT).

Now, technological advances such as proximal or aerial sensing allow scientists to quickly collect information from plants to develop improved varieties.

“Previously, we used to measure maize height with a stick, and manually capture the data” he said. “Now we use proximal sensing—a laser distance meter connected to your phone or tablet that automatically captures data —to measure plant height 2 to 3 times faster for half of the labor. We also use digital ear imaging to analyze maize ear and kernel attributes including grain yields  without having to shell the cobs, saving time and money on labor. This will be helpful particularly to most of our partners who do not own the machinery required for shelling after harvest”

Zaman-Allah also works with aerial sensing, using unmanned aerial vehicles equipped with sensors to fly over crop fields and collect images that are later processed to extract crop phenotypic data. “Aerial phenotyping platforms enable us to collect data from 1,000 plots in 10 minutes or less, a task that might take eight hours to do manually,” he said.

This means that developing improved maize varieties with tolerance to heat and drought, as well as devastating diseases such as maize lethal necrosis (MLN), could become faster and more cost-effective than ever before. Application of aerial and proximal sensing technology for high-throughput phenotyping, in which large amounts of data are processed simultaneously, provides high-resolution measurements for research plots that can enable the rapid identification of stress tolerant varieties, speeding up the breeding process.

The time and money saved by using these technologies allow researchers to develop and deploy improved varieties more quickly to the smallholder farmers that need them most, which is especially important as climate change begins to change growing environments faster than traditional varieties can adapt.

For Zaman-Allah, this interest in improving agriculture for all is “in the blood,” he said. While growing up in Niger, his family had to move to a different city every three years due to his father’s job. “Everywhere we moved; my father made sure that we rented or bought a small farm, where I would be involved in crop production every year during the long vacations over the rainy season. That was a wonderful experience as I learned a lot regarding crop production, drought and soil fertility management.”

He would take this first-hand experience in agriculture to the next level while earning undergraduate and postgraduate degrees at the University of Carthage in Tunisia and conducting research for his Ph.D. in plant eco-physiology at the French National Institute for Agricultural Research (INRA) through a grant from the French Agency for International Cooperation.

Zaman-Allah joined CIMMYT in late 2012 as a scientist with a specialization in heat and stress resilient maize, based in Harare, Zimbabwe. He has been working as an abiotic stress phenotyping specialist since late 2015, and is considered a pioneer in remote sensing work in CIMMYT maize breeding. In addition to his work as a scientist, he also writes codes for the programs used in proximal sensing.

“As part of my current job, I develop, test and validate low-cost and high-throughput field-based phenotyping tools and methods for different desired traits in crops, including drought, heat and low-nitrogen stress,” he said.

“My team is working to provide opportunities toward next-generation phenotyping that is more compatible with maize breeders needs and that will significantly minimize selection cost while maximizing selection efficiency, accelerating the process to deliver maize varieties with better genetic traits to farmers.”

Zaman-Allah’s commitment to food security extends beyond his job. On his own time, he shares knowledge gained at CIMMYT to inform his contacts at universities and national agricultural research centers in Niger and help increase his home country’s capacity to produce healthy crops.

“Maize and wheat are not usually grown in Niger due to heat, drought and low soil fertility, but due to recent advances in CIMMYT technologies and improved varieties, they are now a possibility,” he said. “People were doubtful at first, but when improved varieties from CIMMYT Mexico and CIMMYT-Zimbabwe were planted side by side with locally released varieties, there was no comparison—the CIMMYT varieties performed far better.”

Working at CIMMYT has given Zaman-Allah a unique opportunity to help farmers while also working with a top-notch international team.

“I really enjoy the teamwork, the innovation and the challenge to make a difference,” he said. “It’s immensely satisfying to be able to contribute in helping smallholder farmers through my work. Whenever I take vacation, I always go back to the village in Niger where my family is from, and I love to talk with local farmers about the latest agricultural technologies that could help them.”

New sustainable agriculture initiative targets India’s second most populous state

JAWHAR, India (CIMMYT) – A new project is bringing sustainable technologies and practices to one-thousand villages in Maharashtra, India, the second most populous state in the country and an area that is particularly vulnerable to climate change effects like erratic rainfall, heat waves, sea water intrusion and other climatic risks.

Agriculture provides income for over half of Maharashtra’s population, yet productivity is severely affected by climate change and unsustainable agricultural practices that degrade soil quality. In 2015 alone 60 percent of villages in the state suffered drought affecting nearly nine million farmers.

New “climate smart” practices are critical if farmers in Maharashtra are to survive future climatic shocks, improve productivity and maintain a healthy ecosystem. The state has the second largest tribal population in the country, with most of these communities inhabiting fringe forest settlements and degraded lands which have low productivity and high vulnerability to erosion, making it even more vital farmers adopt sustainable practices.

A Climate Smart Village Programme for the Tribal Regions of Maharashtra was launched  to promote these practices – such as zero-till farming, integrated nutrient and water management and proper harvesting and storage – targeting farmers across Maharashtra’s tribal belt.

The three-year project, launched in 2016, is being implemented across over 1,000 villages in the state. Last year, 100 primary villages were identified as most likely to adopt climate smart practices in Maharashtra’s three districts and chosen to implement sustainable agriculture practices. Farmers groups from each primary village will link for the last two years of the project with nine skilled-up villages – villages where at least one climate smart practice has been adopted – to share and help implement climate smart farming practices and techniques.

Large quantities of improved seed that are resilient to drought, heat and other stresses are also being provided to use alongside these practices, ensuring maximum yield.

A key aspect of the program is ensuring that the climate smart technologies being promoted are adapted to local conditions – it’s critical that these new tools can be used by small and marginal farmers at an affordable cost. The International Maize and Wheat Improvement Center through the Borlaug Institute for South Asia (BISA) are currently distributing different small scale farm machineries like fertilizer drills and threshers that are catered to farmer preferences, including women farmers in the 100 primary villages.

Information and Communication Technology (ICT) advisories will also be provided to farmers to ensure they have access to real-time information on weather forecasts, pest and disease outbreaks, market intelligence and more. BISA in collaboration with IFFCO Kishan Sanchar Limited, a telecommunications company in New Delhi, will release a mobile based ICT service in 2017 to provide advisories to enrolled farmers. 4,000 farmers have been selected for the service this year. The service will be constantly monitored and upgraded as required to meet the needs of more than 50,000 farmers over the course of the project.

The final component of the project ensures that farmers are enrolled in crop insurance schemes, which is essential to protecting and reimbursing farmers should their crops fail under poor climate conditions. BISA enrolled 500 farmers for insurance from November 2016-March 2017 and in the process to enroll more farmers in the coming monsoon season during July-October of this year.

In early June, Shri Vishnu Savara, Minister of Maharashtra’s Tribal Development Office, chaired an event that brought delegates from across India to review the current progress of the project in Jawhar, Palghar District. The event was facilitated by BISA representatives including Senior Consultant Prakash Naik, Hub Coordinators Abhilash Gupta and Mahesh Maske, Executive Assistant Anu Raswant and Administrative Officer Manish Rai. The event was co-chaired by Shri R. G. Kulkarni, Commissioner of Maharashtra’s Tribal Development Office and Arun Joshi, CIMMYT Asia Regional Representative.

Savara emphasized the important impact climate smart agriculture coupled with improved seed can have on farm productivity across Maharashtra’s tribal areas, and new ability to adapt to future climatic shocks and extreme weather events.

Increased investment needed to adapt Africa’s agriculture to climate change

HARARE, Zimbabwe (CIMMYT) – Delegates at a conference in June called for a new focus and increase in investment to ensure eastern and southern Africa’s farming systems can withstand the impacts of climate change.

Africa is likely to be the continent most vulnerable to climate change, according to the UN Framework Convention on Climate Change. Smallholders produce around 80 percent of all food in sub-Saharan Africa, and rely primarily on rainfall for irrigation – a source that is becoming scarcer and unpredictable under climate change. Farming is also often practiced in marginal areas like flood plains or hillsides, where increasing and more intense weather shocks cause severe damage to soil and crops.

Tanzania’s Minister for Agriculture, Food Security and Cooperatives Charles Tizeba said during a conference on the future of the Sustainable Intensification of Maize-Legume Based Cropping Systems for Food Security in Eastern and Southern Africa (SIMLESA) project, an initiative led by the International Maize and Wheat Improvement Center (CIMMYT) and funded by the Australian Centre for International Agricultural Research (ACIAR), that a paradigm shift in agricultural development is needed to enable smallholder farmers, especially those in rural areas, to produce enough to feed themselves and to sell.

Sustainable agricultural practices, improved seed varieties, use of fertilizers and better infrastructure are all technologies and practices that have been successfully tested by SIMLESA and have the potential to be expanded across the region, said Tizeba. He also called on governments in eastern and southern Africa to develop agricultural agendas based on farmer needs and opportunities SIMLESA identified through the project’s research efforts.

Over 100 people representing different governments, research institutions, development agencies and the private sector gathered in Tanzania to participate in the taking stock on sustainable intensification research for impact in eastern and southern Africa conference. Since 2010, SIMLESA has successfully tested locally-adapted sustainable farming systems throughout eastern and southern Africa. The project began its second phase in July 2014 and will focus on expanding climate-resilient technologies and practices throughout the region.

To date, a total of 268 and 378 maize and legume on-farm participatory variety selections were conducted by SIMLESA, where best performing maize and legume varieties that met farmer preferences were selected and scaled up by partner seed companies. The project has influenced over 235,000 farmers who adopted at least one sustainable intensification technology or practice.

CIMMYT Director General Martin Kropff called for the adoption of “climate-smart agriculture” that will make crops more resilient to continuing extreme weather events.

“For our farmers to be productive and ensure food security, we need to build resilience to climate change…we need to invest in new agricultural innovation now,” said Kropff.

Andrew Campbell, ACIAR chief executive officer, said climate change has already had a powerful negative effect on agriculture and food security for the world’s most vulnerable, and that these effects will become even worse in the future.

“It’s critical to integrate research into development initiatives,” said Campbell. “In this regard, SIMLESA’s work, in partnership with national agricultural research systems, becomes even more critical.”

At the project level, SIMLESA will aim to scale its sustainable intensification technologies to 650,000 farm households by 2023 in eight target countries through different partnership arrangements.

Many of the speakers at last week’s event said smallholder farmers must be part of discussions on climate change and food security as they are often among those most touched by the impacts of climate change, and they play an integral role in global agriculture systems.

To achieve the best results, SIMLESA will channel its experiences and lessons learned since its inception in 2010 and scale out its work through shared analysis, common research questions and learning through the monitoring, evaluation and learning portfolio, communications and knowledge sharing and a lean project management structure.

SIMLESA’s positive assessment of conservation agriculture-based sustainable intensification in the region suggests that policies that strengthen national and local institutions, build infrastructure for sustainable farming, improve financial investment in agriculture and increase access for innovative private investors, play a key role in alleviating poverty and food insecurity in the region.

The Sustainable Intensification of Maize-Legume Based Cropping Systems for Food Security in Eastern and Southern Africa (SIMLESA) project was launched in 2010. Funded by the Australian Centre for International Agricultural Research (ACIAR), SIMLESA aims to improve the livelihoods of smallholder farming communities in Africa through productive and sustainable maize–legume systems and risk management strategies that conserve natural resources. It is managed by CIMMYT and implemented by partners in Ethiopia, Kenya, Malawi, Mozambique and Tanzania.

NAIROBI (CIMMYT) – Climate change’s impact in eastern and southern Africa has driven many farmers to seek new planting techniques that maintain or increase crop production, despite fewer resources.

The World Bank forecasts show that climate change will push Africa to surpass Asia as the most food insecure region in the world, inhabiting up to 50 percent of undernourished people globally in 2080. Variations in temperature and precipitation, coupled with prolonged droughts and floods during El Nino events is predicted to have a devastating impact in the region where 95 percent of all agriculture is dependent on rainfall.

Farmers in eastern and southern Africa are already feeling the impacts of climate change, and changing the way they make a living because of it through new agricultural adaptation strategies.

Sustainable practices like growing two or more crops among each other, or intercropping, have become popular with smallholder farmers in Africa who often plant multiple crops. When used in combination with improved seeds with traits like drought or disease resistance, these farmers are able to have successful harvests despite challenges imposed by climate change.

Knowing how to manage an intercropping system is vital to its success. Cereals and legumes in an intercrop system must have different growth habits and rooting patterns to reduce competition for nutrients, light and water.

According to Leonard Rusinamhodzi, an agronomist at the International Maize and Wheat Improvement Center (CIMMYT), farmers also need to reduce herbicide use in intercropping systems.

“It’s difficult to apply selective herbicides in systems with both narrow and broad leaf crops,” said Rusinamhodzi, who is working with farmers to apply the best fertilizer practices to their intercropped plots. “Maize will require mostly nitrogen, phosphate and potassium basal fertilizer, while legumes will require mostly phosphate and potassium, and micronutrients such as zinc and boron. Proper rates and proportions for all fertilizers and nutrients is crucial to ensure both crops are properly nourished.”

Another major consideration of intercropping is arrangement of crops in the field. A common approach is to alternate one row of maize with one row of a legume, but in Kenya, two rows of a legume alternating with two rows of maize is preferred. This arrangement, known as the MBILI system (mbili meaning “two” in Kiswahili) in Kenya, reduces competition between the maize and legumes, which leads to higher yield for both crops.

Arrangements of intercrops: Left, the MBILI system characterized by two rows of a legume alternating with two rows of maize. On the right is the commonly used intercropping arrangement with alternating rows of component crops, that is, one row of maize followed by one row of the legume.

CIMMYT promotes the adoption of intercropping and other sustainable agriculture techniques through participatory farmer evaluations (PFEs) eastern and southern Africa. PFEs allow farmers to assess crops at demonstration plots and compare a range of improved seed products against local and traditional seed.

In Makueni County, Kenya, where most farmers grow cereals and legumes together, on-station intercropping trials comprising five drought tolerant maize varieties, six bean varieties and six pigeonpea varieties were set up in 2016 and replicated on several smallholder farmers’ plots. In 2017, the Participatory Evaluation and Application of Climate Smart Agriculture – PEACSA – project invited farmers to score and rate the performance of the crop varieties planted right before harvest time through a PFE.

By comparing crop performance, smallholder farmers are able to see first-hand that when used in combination with improved seed, sustainable techniques like intercropping are key to successful yields and quality seed. Because of this PFEs also create awareness of new products while simultaneously delivering detailed technical knowledge in a more convincing, hands-on manner.

About PEACSA:

Participatory Evaluation and Application of Climate Smart Agriculture (PEACSA) is a flagship project of the Research Program on Climate Change, Agriculture and Food Security (CCAFS), in collaboration with different agricultural research organizations, including CIMMYT. Through the PEACSA project a variety of best-bet CSA practices are applied at both on station and on farm levels, in an effort to test and evaluate appropriate technologies to increase agricultural productivity and enhance food security. With participatory evaluation, uptake and adoption of new technologies, especially improved seed varieties, is greatly increased because farmers take stock of the traits that matter to them. Cob size, kernel type, and length of maturity are just some of the characteristics farmers can rate in a participatory evaluation exercise.

About DTMASS:

Led by the International Maize and Wheat Improvement Center (CIMMYT) and funded by the United States Agency for International Development (USAID), the Drought Tolerant Maize for Africa Seed Scaling (DTMASS) project works in six countries in eastern and southern Africa to produce and deploy affordable drought tolerant, stress resilient, and high-yielding maize varieties for smallholder farmers. In 2016, DTMASS conducted PFEs in Mozambique and Zambia in collaboration with partners, and aims to conduct dozens more in 2017, across all project target countries.

MEXICO CITY (CIMMYT) — Farmers in Pakistan that practice climate change adaptation strategies like adjusting sowing time, adopting new crops and planting drought tolerant varieties have higher food security levels and are less likely to live in poverty than those that don’t, according to a new study.

South Asia is likely to be one of the most affected regions by climate change due to the region’s vast agrarian population and large number of poor, unfavorable geography, limited assets and a greater dependence on climate-sensitive sources of income.

In Pakistan, climate change has had a direct impact on rain patterns and increased the frequency of extreme weather events such as flash floods. Adaptation measures at the farm level can help lessen the impact of these negative effects on food security.

Researchers from the International Maize and Wheat Improvement Center (CIMMYT) recently surveyed 950 farmers across Pakistan to see what adaptation measures to climate change they use, if any.

The study found that farmers in Pakistan are using a variety of adaptation practices to counter the adverse impacts of climate change, primarily adjusting sowing time, adopting new crops and planting drought tolerant varieties. The results also highlighted the importance of awareness and knowledge about the local context, climate change, adaptation and its benefits. Younger farmers and farmers with higher levels of education are also more likely to use these adaptation practices, as do farmers that are wealthier, farm more land and have joint families.

The authors of the study conclude that adaptation policies should focus on increasing the awareness of climate change and climate risk coping strategies and its benefits, as well as increasing the affordability of climate risk coping capacity by augmenting the farm household assets and lowering the cost of adaptation.

MEXICO CITY (CIMMYT) – The International Maize and Wheat Improvement Center (CIMMYT) has grown 150 tons of renewed, improved maize seed that will be sent to Haitian farmers to help jump-start the country’s seed sector, improve local food security and decrease malnutrition. This will be the largest seed shipment to any country in CIMMYT’s history.

In 1998, CIMMYT, together with the Organization for the Rehabilitation of the Environment, introduced a new quality protein maize variety in Haiti. Named “Hugo” for CIMMYT maize breeder Hugo Córdova, the variety grew well under the island’s agro-ecological conditions and can decrease malnutrition and stunting among children that consume it. The product of decades of maize research in Haiti and Latin America, Hugo quickly became a favorite among farmers, but over time lost its genetic purity due to a lack of certified seed production and yields began to drop.

Now, CIMMYT is working to help Haiti build their seed sector from the ground up, from developing improved seed to replace old varieties to providing capacity development at every level of the maize seed value chain, with incredible results.

Haiti is the poorest country in Latin America and the Caribbean, with the lowest maize yields in the continent, and roughly 50 percent of the population is undernourished. These conditions have been exacerbated by a crippling earthquake in 2010, what is emerging as a longstanding drought, and devastating Hurricane Matthew in 2016 that affected 2 million people. According to the United States Agency for International Development (USAID), Haiti cannot achieve economic growth and national stability if food security is not addressed.

However, improving food security in Haiti is complicated by the fact that there are no formal seed companies, said Alberto Chassaigne, maize seed system specialist at CIMMYT.

“Farmers often sell their entire crop at harvest, leaving nothing for the next season, forcing them to plant simple maize grain that they buy from local markets rather than certified seed, drastically reducing yield over time,” said Chassaigne.

In 2015, CIMMYT launched the Mayi Plus initiative with the support of USAID-Haiti Feed the Future (FTF) to identify the most promising varieties for the future of maize farming in Haiti. The project would also work to produce a “renewed” Hugo to farmers in Haiti with greater genetic purity and yield, and provide capacity development to Haitians in the production and processing of seed of these improved varieties. This renewed Hugo, known as “Hugo Plus,” can produce up to seven tons per hectare, in comparison to traditional varieties currently planted in Haiti that produce on average less than one ton per hectare.

Through a systemic series of maize trials, scientists also found that new CIMMYT germplasm is already available that outperforms any other maize available in Haiti in both irrigated and rain-fed conditions.  These resilient varieties, named “Mayi Plus I” and “Mayi Plus II” are currently under multiplication to be introduced to Haitian farmers as soon as possible.

Four tons of renewed Hugo were produced in 2015, 2.7 tons of which were produced in Haiti.

In the winter cropping season of 2016-2017, CIMMYT produced 150 tons of renewed Hugo seed in Mexico to send to Haiti, 50 percent more than the 100 tons they had planned to send. “This is the largest seed shipment ever sent by CIMMYT,” said Arturo Silva Hinojosa, leader of the International Maize Improvement Consortium in Latin America. “An additional 15 tons of seed will be harvested in Haiti, up from 0-3 tons in previous years.”

20 of the 150 tons of renewed “Hugo Plus” have already arrived in Haiti, where they will be sold to farmers at affordable prices in “agricultural input boutiques” established by FTF and partners. The remaining 130 tons will be used by CIMMYT and FTF to develop a strategic seed reserve in Haiti that will serve as a backup in case of natural disasters so that the country has immediate availability of seed stock for re-planting. The CIMMYT team in Haiti is currently working to find the best locations to store the strategic maize seed reserve.

To ensure that the genetic purity of renewed Hugo and other improved maize varieties will be maintained, CIMMYT is providing capacity development to help start Haiti’s seed sector from scratch. Project partners identified entrepreneurs interested in establishing a seed enterprise, and CIMMYT has been providing these entrepreneurs with in-depth training in seed processing and marketing, guidance on the infrastructure for a seed processing plant, and contacts throughout the world of equipment appropriate for Haitian conditions.

In addition, CIMMYT established a two-week course in seed production and seed processing with a FTF partner to train 13 Haitian technicians, who will now be able to train other Haitians interested in working in the country’s maize seed sector. A training manual is being prepared in French and Creole, and replication workshops will be conducted in target food security corridors of USAID in Haiti.

“This improved seed, and a self-sustaining seed sector capable of producing and marketing it, can contribute towards improved foreign exchange savings and will create local employment,” said Huntington Hobbs, former leader of strategic planning and research coordination for CIMMYT’s MasAgro project. “Increased maize production will bolster Haiti’s economy by providing feed for emerging industries in poultry and egg production, as well as the main staple of Haitian food security.”

CIMMYT researchers returned to Haiti in early June to advise seed companies on the installation of a seed processing plant, as well as to supervise trials and evaluations of new varieties and coordinate trainings in Haiti with trainers trained last February in Mexico.

In order to introduce local farmers to the new Hugo Plus maize variety and recognize CIMMYT’s contribution to Haiti’s food security through the Mayi Plus project, the USAID-Haiti Feed the Future Chanje Lavi Plante (CLP) project held a special event on June 21, 2016. The event was attended by farmers, agricultural input store managers and local partners, as well as staff from the Haitian Ministry of Agriculture and USAID who thanked CIMMYT for the recent 20 ton seed shipment.

“Hugo Plus is the result of many years of applied research work of CIMMYT in Haiti, and is a valuable alternative to the current varieties available in Haiti with such low yields,” said Micheal Wyzan, head of the office of economic growth and development at the Haiti mission of USAID. “We highly appreciate the fruitful collaboration between CIMMYT and the CLP project that allow farmers to increase their maize yields in the region.”

In his address to the audience, Alain Thermil, main liaison of Haiti’s Ministry of Agriculture with USAID, stated that, “CIMMYT is a very important organization in the world, and it is vital to Haiti that we establish and maintain a close relationship with CIMMYT.”

Jean Robert Estime, director of the CLP project in Haiti, agreed. “Through CIMMYT interventions, good quality seed is now available to farmers in Haiti. We are very grateful to CIMMYT, a great international organization with a mandate to do research on maize and wheat worldwide that is doing very important work in Haiti.”

ISLAMABAD (CIMMYT) – Farmers in Pakistan are eagerly adopting a nutrient-enhanced wheat variety offering improved food security, higher incomes, health benefits and a delicious taste.

Known as Zincol and released to farmers in 2016, the variety provides harvests as abundant as those for other widely grown wheat varieties, but its grain contains 20 percent more zinc, a critical micronutrient missing in the diets of many poor people in South Asia.

Due to these benefits and its delicious taste, Zincol was one of the top choices among farmers testing 12 new wheat varieties in 2016.

“I would eat twice as many chappatis of Zincol as of other wheat varieties,” said Munib Khan, a farmer in Gujar Khan, Rawalpindi District, Punjab Province, Pakistan, referring to its delicious flavor.

Khan has been growing Zincol since its release. In 2017, he planted a large portion of his wheat fields with the seed, as did members of the Gujar Khan Seed Producer Group to which he belongs.

The group is one of 21 seed producer associations established to grow quality seed of new wheat varieties with assistance from the country’s National Rural Support Program (NRSP) in remote areas of Pakistan. The support program is a key partner in the Pakistan Agricultural Innovation Program (AIP), led by the International Maize and Wheat Improvement Center (CIMMYT) and funded by the U.S. Agency for International Development (USAID).

“Over the 2016 and 2017 cropping seasons, 400 tons of seed of Zincol has been shared with farmers, seed companies and promotional partners,” said Imtiaz Muhammad, CIMMYT country representative in Pakistan and a wheat improvement specialist.

Zincol resulted from the CIMMYT’s “biofortification” breeding research, focused on enhancing nutrient levels in the grain of key food crops. Scientists develop biofortified crops using diverse genetic resources, including wheat landraces and wild relatives with the genetic potential to accumulate zinc in the grain.

Genes for enhanced grain zinc content from those sources are crossed into adapted, high-yielding varieties, over repeated cycles of selection involving many thousands of plants.

“One year after the release of Zincol, wheat farmers on more than 320 hectares are sowing the variety,” Imtiaz said.

He also noted that 15 tons of Zincol seed was shared free of charge for testing with 600 farm families in Sukkar District, Sindh Province, through an initiative of World Vision-Canada and HarvestPlus, a CGIAR research program dedicated to the study and delivery of biofortified foods.

Wheat: Vehicle for enhanced nutrition

Pakistan produces more than 25 million tons of wheat a year. The country has an annual per capita consumption averaging around 124 kilograms — among the highest in the world and providing over 60 percent of inhabitants’ daily caloric intake. The staple wheat-based foods are chappatis or a flat bread baked on the walls of large, cylindrical clay ovens.

Particularly in remote areas of Pakistan, human diets too often lack essential micronutrients such as zinc. 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.

Zinc deficiency is also known to cause diarrheal disease, lower respiratory tract infections, malaria, hypogonadism, impaired immune function, skin disorders, cognitive dysfunction and anorexia, according to the World Health Organization.

“Given its role as a key food staple, wheat with enhanced levels of zinc and other micronutrients can contribute to better nutrition,” said Velu Govindan, a CIMMYT wheat breeder who specializes in biofortification and helped develop Zincol.

“Zincol also carries the genetic background of NARC 2011, a popular, high-yielding Pakistan wheat variety that resists wheat stem rust, a deadly disease that threatens wheat worldwide,” Govindan added.

As part of AIP and HarvestPlus, as well as with numerous public and private partners and farmer seed production groups in Pakistan, CIMMYT is leading the extensive evaluation, distribution and seed production of Zincol, said Krishna Dev Joshi, a former CIMMYT wheat improvement specialist who worked on the project.

“With modest resources and limited amounts of seed, we tested and promoted Zincol over the last two years in Balochistan, Punjab, and Sindh, covering 15 districts and engaging nearly 700 farmers,” Joshi explained.

Joshi said farmer seed producers and private seed companies were able to provide another 100 tons of seed in 2016, enough to sow more than 2,500 hectares in 2017 and over half a million hectares in 2018.

“Zincol reached farmers nine years after the initial breeding cross in 2007, several years more quickly than is the norm in Pakistan, partly because it was tested simultaneously in national and provincial trials,” Joshi added. “Zincol is part of a suite of new, micronutrient-enhanced wheat varieties bred by CIMMYT and partners for use in South Asia, a region whose inhabitants consume 100 million tons of wheat each year.”

For India, Govindan and partners created a new biofortified wheat variety using synthetic parents crossed onto WH1105, a CIMMYT-derived high-yielding variety grown in India’s Northwestern Plain Zone. The new variety out-yields other popular varieties by as much as 8 percent and has a 20 percent higher zinc content, as well as good resistance to yellow rust disease. Another new Indian variety, Zinc Shakti, has a 40 percent greater grain zinc content and is being marketed by the private sector and spread via farmer-to-farmer seed sharing.

CSIRO and CIMMYT link on wheat phenomics, physiology and data

Written by Mike Listman on . Posted in Features.

CSIRO Workshop-GroupCroppedBuilding on a more than 40-year-old partnership in crop modelling and physiology, a two-day workshop organized by CIMMYT and Australia’s Commonwealth Scientific and Industrial Research Organisation (CSIRO) achieved critical steps towards a common framework for field phenotyping techniques, data interoperability and sharing experience.

Involving 23 scientists from both organizations and held at El Batán from 12 to 13 June 2017, the event emerged partly from a 2016 visit to CIMMYT by CSIRO Agriculture and Food executives and focused on wheat, according to Matthew Reynolds, CIMMYT wheat physiologist and distinguished scientist.

“Capitalizing on our respective strengths, we developed basic concepts for several collaborations in physiology and breeding, and will follow up within ongoing projects and through pursuit of new funding,” Reynolds said, signaling the following:

  • Comparison of technologies to estimate key crop traits, including GreenSeeker and hyperspectral images, IR thermometry, digital imagery and LiDAR approaches, while testing and validating prediction of phenotypic traits using UAV (drone) imagery.
  • Study of major differences between spike and leaf photosynthesis, and attempts to standardize gas exchange between field and controlled environments.
  • Work with breeders to screen advanced lines for photosynthetic traits in breeding nurseries, including proof of concept to link higher photosynthetic efficiency / performance to biomass accumulation.
  • Validation/testing of wheat simulation model for efficient use of radiation.
  • Evaluation of opportunities to provide environment characterization of phenotyping platforms, including systematic field/soil mapping to help design plot and treatment layouts, considering bioassays from aerial images as well as soil characteristics such as pH, salinity, and others.
  • Testing the heritability of phenotypic expression from parents to their higher-yielding progeny in both Mexico and Australia.
  • Extraction of new remote sensed traits (e.g., number of heads per plot) from aerial images by machine learning (ML) of scored traits by breeders and use of ML to teach those to the algorithm.
  • Demonstrating a semantic data framework’s use in identifying specific genotypes for strategic crossing, based on phenotypes.
  • Exchanging suitable data sets to test the interoperability of available data management tools, focusing on the suitability of the Phenomics Ontology Driven Data (PODD) platform for phenotypic data exchanges, integration, and retrieval.

The shared history of the two organizations in wheat physiology goes back to the hiring by Dr. Norman E. Borlaug, former CIMMYT wheat scientist and Nobel Prize laureate, of post-doctoral fellow Tony Fischer in 1970. Now an Honorary Research Fellow at CSIRO, Fischer served as director of CIMMYT’s global wheat program from 1989 to 1996 and developed important publications on wheat physiology earlier in his career, based on data from research at CIMMYT. In the early 1990s, Lloyd Evans, who established the Canberra Phytotron at CSIRO in the 1970s, served on CIMMYT’s Board of Trustees. Former CIMMYT maize post-doc Scott Chapman left for CSIRO in the mid-1990s but has partnered continuously with the Center on crop modelling and remote sensing. With funding from the Australian Centre for International Agricultural Research (ACIAR) in the late 1990s, CSIRO scientists Richard Richards, Tony Condon, Greg Rebetzke and Graham Farquhar began shared research with Reynolds and Martin van Ginkel, a CIMMYT wheat breeder, on stomatal aperture traits. Following work at CSIRO with Lynne McIntyre and Chapman, scientist Ky Matthews led the CIMMYT Biometrics Group from 2011 to 2012, collaborating with CIMMYT wheat physiologists on a landmark project to map complex physiological traits using the purpose-designed population, Seri/Babax. Reflecting the recent focus on climate resilience traits, Fernanda Dreccer of CSIRO is helping CIMMYT to establish the Heat and Drought Wheat Improvement Consortium (HeDWIC), among other important collaborations.

ISLAMABAD (CIMMYT) – Farmers and research partners are praising innovative, locally manufactured farm implements that support conservation agriculture, with costs savings and soil and water conservation benefits, in rice-wheat farming rotation that cover more than 2.2 million hectares in Pakistan.

In a meeting in May 2017 at the Rice Research Institute Kala Shah Kaku, Punjab Province, Pakistan, farmers expressed satisfaction with the performance of nearly 200 locally-produced implements they received to test during 2016-2017, which allow seed of rice, wheat and other crops to be sown directly into unplowed and unflooded fields, including the stubble and other residues from preceding crops.

In traditional practices, rice plantlets are transplanted by hand into puddled fields, after 4 to 6 weeks of being grown in nurseries on the borders of the paddies.

“This requires enormous amounts of water and labor, both of which are expensive and in short supply,” said Muhammad Akhter, Director of Pakistan’s Rice Research Institute. “Moreover, puddling every season degrades the soil structure and depletes fertility, and flooded rice fields emit significant amounts of methane, a major greenhouse gas.”

After rice harvest, farmers typically burn rice residues, generating large noxious clouds, and drive tractor-drawn plows repeated over fields to prepare seed bed. They then sow wheat through broadcasting of the seed.

Since the 1990s, public research programs in South Asia have been working with the International Maize and Wheat Improvement Center (CIMMYT) and advanced research institutes to test and promote a suite of innovative practices, including reduced or zero tillage, which allow rice-wheat farmers to save money, better steward soil and water resources, cut greenhouse gas emissions and stop the burning of crop residues.

Direct seeding of rice in unplowed, unpuddled fields can provide improved plant density and productivity of irrigation water, saving in the end a quarter of the water used in flooding rice crops.

In 2014, the CIMMYT-led Agricultural Innovation Program (AIP), supported by the United States Agency for Development (USAID), imported a multicrop zero tillage planter for rice and several zero tillage “Happy Seeders” to Pakistan from India for wheat, to be tested on farmers’ fields in five districts of Punjab by experts from the Punjab Agriculture Research and Extension Department, Engro Fertilizer and machinery manufacturers.

All tests were successful, and the following year CIMMYT worked with private machinery manufactures who produced the first locally-modified versions of both seeding implements.

Greenland Engineering Daska, a leading zero tillage drill manufacturer in Pakistan, collaborated with CIMMYT to adapt the rice planter’s inclined plate seeding system, offering an optimum planting density and thereby providing 10 percent higher rice yields than with the previous design.

Sharif Engineering, a zero tillage seed drill manufacturer of the Faisalabad region, modified the Happy Seeder so that farmers were able to sow wheat directly into heavy rice residue field and thus avoid burning the residues.

Sharif Engineering manufactured 13 Happy Seeders with AIP support; these were sold to farmers on 52:48 cost sharing basis in 2016, according to Mirza Ghazanfar, country representative for the company. Irfan Iqbal of Greenland Engineering said that company had produced and marketed 185 rice planters to farmers during 2016-17.

Akhter praised the efforts of USAID and CIMMYT to spread environmentally-friendly rice-wheat farming technologies to farmers of rice-wheat region.

KRASNODAR, Russia (CIMMYT) – The sixth International Winter Wheat Travelling Seminar was recently held in Krasnodar, Russia, to improve wheat breeding across West and Central Asia.

Wheat is a staple in Central and West Asia and is critical to food security in the region. The biannual traveling seminar allows breeders from across the region to tackle challenges like climate change’s impact on wheat production, the spread of rust disease and improving grain quality.

The seminar was first launched in 2007 by the International Winter Wheat Improvement Program (IWWIP), a partnership between Turkey’s Ministry of Food, Agriculture and Livestock, the International Maize and Wheat Improvement Center and the International Center for Agricultural Research in the Dry Areas to bringing together IWWIP members from Central and West Asia to share the results, discuss challenges and develop future plans for cooperation. Previous seminars were held in Azerbaijan, Bulgaria, Georgia, Romania, Turkey, Ukraine and Uzbekistan.

Through IWWIP, improved wheat varieties are annually distributed from the Facultative and Winter Wheat Observation Nursery in Turkey to more than 100 partners in 50 countries.  To date, more than 70 varieties have been released in Central and West Asia by IWWIP, covering up to 20 percent of all wheat grown in the region.

The seminar was held at the Krasnodar Agricultural Research Institute and Agricultural Research Center, attracting 74 participants from 17 countries in Central and West Asia, as well as Eastern and Western Europe.

Participants were shown wheat breeding and research plots, as well as multiplication of new barley and wheat varieties. The group was highly impressed by the level of breeding and research activities, the diversity of the germplasm and its yield potential. Varieties from the Krasnodar Institute are grown on several million hectares in Russia and other countries, contributing to regional and global food security. In the afternoon, several presentations were made from hosts and guests reviewing the current status of winter wheat improvement and regional collaboration. Participants also focused on breeding and agronomy activities.

The group also traveled to a farm in Rostov, Russia, that was demonstrating different winter wheat varieties and saw two seed production state farms that multiply the varieties from the Krasnodar Institute. All the fields visited were very well maintained, clean and with yield expectations exceeding 7-8 tons per hectare. More than two million hectares of wheat is grown in Rostov, providing about 8 percent of Russia’s total wheat.

Winter wheat varieties from Russian public breeding programs dominate about 95 percent of the country’s production area, though local and multinational private companies are increasingly emerging as key players in the sector.

A wrap up meeting was held with several presentations by the participants and the IWWIP strategy was presented and endorsed. Participants also stated their appreciation for the organizers, Krasnodar Agricultural Research Institute, and for IWWIP’s activities in developing and distributing germplasm. The event was supported by the Turkish government, the CGIAR Research Program on WHEAT and the Food and Agriculture Organization of the United Nations.

Breaking Ground: More data on gender roles key for a food secure world, says Anya Umantseva

Written by on . Posted in Features.

Breaking Ground is a regular series featuring staff at CIMMYT

TwitterBGAnyaEL BATAN, Mexico (CIMMYT) – Social inequality, including gender discrimination, hinders the potential for economic development, a key focus of the agriculture for development community.

Women in developing countries make up more than 40 percent of waged farmworkers, a percentage that is even higher if unwaged farm work is included, according to the U.N. Food and Agriculture Organization. Despite their significant representation in the sector, women often experience acute poverty due to unequal access to seeds, fertilizer, land and other agricultural necessities.

The challenges are great, but the aim of achieving gender equality and empowering all women and girls everywhere by 2030 is entrenched in the international development framework by the U.N. Sustainable Development Goals (SDGs).

Spurred on by the SDGs, gender has become a key agricultural research and policy focus for the International Maize and Wheat Improvement Center (CIMMYT) and the CGIAR system research programs in recent years.

“Despite improvement, there are still several opportunities which could significantly decrease inequality between men and women,” said CIMMYT gender researcher Anya Umantseva. “Little data exists on gender roles in rural communities and most importantly, a systematic integration of social components like gender into scientific, data-based research could really help expand outcomes and impacts to more women as well as men.

“Women in rural communities often face very strict gender norms,” said Umantseva, referring to local women’s and men’s expected roles and behaviors. “What we’re trying to do is see how these norms influence the way men and women adopt agricultural innovations, and how adoption of different innovations affects gender norms across different communities.”

Umantseva is one of many researchers working on GENNOVATE – a global comparative research initiative, which addresses the question of how gender norms influence men, women and youth to adopt innovation in agriculture and natural resource management.

Gender norms include restricted access to land and financial resources, or even the social taboo of walking alone as a woman, can make it difficult to have equal access to agricultural trainings and other farming inputs, she explained.

Umantseva grew up in Yurga, Russia during the country’s economic transition to capitalism after the fall of the Soviet Union. “Witnessing the abrupt change of political-economic regimes, and the impact it had on society, shaped my interest in social sciences and anthropology,” she said. “I decided that I wanted to study how social norms and culture are historically constructed.”

“Gender in agricultural research for development is not an isolated topic; it is deeply intertwined with social inclusion of disadvantaged groups in general,” Umantseva said. “Gender is not just about men and women, but who these men and women are. Through GENNOVATE we want to go deep into their stories, their socio-economic status, religion, position in the family and more.”

Around 8,000 rural study participants of different ages and socioeconomic backgrounds reflected on gender norms and how these social rules affect their ability to access, adapt and benefit from innovations in agricultural and natural resource management.

“GENNOVATE is the first attempt of this scale  providing this type of gender-based data for agricultural research for development initiatives,” said Umantseva. “But most importantly, we want to convince the research for development community  of the important opportunities, that insights from this kind of data, can bring. It might not always be easy to integrate gender into research, and may require us to do certain things a little differently, but it is necessary if we want to have inclusive development impact.”

Along with other researchers, Umantseva is analyzing GENNOVATE data to produce a series of reports, journal articles and other products so researchers and project managers can begin incorporating GENNOVATE’s findings into their work.

“Right now we’re looking at men and women who have successfully adopted agricultural innovations and what factors their success might have in common, and how men and women differ in adoption. We hope to produce a paper on these findings sometime this year,” said Umantseva.

Umantseva received her bachelor’s degree in linguistics and translation from Russia’s Tomsk State University. She then went on to pursue a master’s at the Catholic University of Leuven in Belgium, where she studied minority policies, ethnic relations and gender norms.

Before she joined CIMMYT in 2016, she worked at the United Nations Office on Drugs and Crime, focusing on human trafficking and migration.  She currently lives in Mexico City and is based at CIMMYT’s Headquarters in El Batan, outside Mexico City.
