Maize is a staple crop that requires a limited amount of water and inputs, and earns farmers a profit, thanks to its growing demand as food and feed for livestock. Adivasi women farmers in India’s Odisha state are increasing their yields by applying improved maize intensification technologies.

The Cereal Systems Initiative for South Asia (CSISA), led by the International Maize and Wheat Improvement Center (CIMMYT), is providing technical support to the Association for Development Initiatives, which implements the Odisha Primitive Tribal Group Empowerment and Livelihood Improvement Program (OPELIP) and the Odisha State Department of Agriculture at Gudugudia in Mayurbhanj.

“CSISA’s technical support to the women, focusing on improved maize cultivation techniques, helped the women improve their understanding, their capacity and their yields,” said Wasim Iftikar, Research Associate at CIMMYT. Improved maize hybrids, precision nutrient management techniques and improved weed management practices have helped the women increase their yields. This year the group harvested more than 3,300 kg from seven acres of land.

“We never thought we could earn money and support our families through maize cultivation. This is an eye-opener for us. We are planning to increase the area of cultivation for maize and will convince our family members and other women to join us,” says farmer Joubani Dehuri.

The Cereal Systems Initiative for South Asia (CSISA) is a regional initiative to sustainably increase the productivity of cereal-based cropping systems, thus improving food security and farmers’ livelihoods in Bangladesh, India and Nepal. CSISA works with public and private partners to support the widespread adoption of resource-conserving and climate-resilient farming technologies and practices. The initiative is led by the International Maize and Wheat Improvement Center (CIMMYT), implemented jointly with the International Food Policy Research Institute (IFPRI) and the International Rice Research Institute (IRRI). It is funded by the U.S. Agency for International Development (USAID) and the Bill & Melinda Gates Foundation.

MEXICO CITY (CIMMYT) — The International Maize and Wheat Improvement Center (CIMMYT) was invited to discuss the findings of the EAT-Lancet Commission report and its implications for Mexico, during a launch event hosted by Mexico’s Health Department on March 4, 2019.

The report, published earlier this year, aims to offer an in-depth scientific analysis of the world’s food production systems and their impact on the planet and human health. It proposes a “planetary health diet” that balances nutrition with sustainable food production.

“Our first objective was to develop healthy diets for the 10 billion people who will inhabit the planet in 2050”, said Juan Ángel Rivera Dommarco, Director General of Mexico’s Public Health Institute and member of the EAT-Lancet Commission. According to Dommarco, the healthy diet recommended for Mexico had to increase the intake of fruits, vegetables, legumes and whole grains to avert chronic diseases and combat malnutrition and obesity.

The report also makes several recommendations to reduce the environmental impact of food production, taking into account planetary boundaries. “The world needs to sustainably intensify food production and to produce basic foodstuffs of higher nutritional value”, said Fabrice DeClerck, EAT’s Science Director.

“If anybody is able to manage the complex systems that will sustainably yield the volume of nutritious food that the world needs, that’s the farmer”, said Bram Govaerts, Director of Innovative Business Strategies at CIMMYT. “In Mexico, more than 500 thousand farmers already innovate every day and grow maize, wheat and related crops under sustainable intensification practices that CIMMYT and Mexico’s Agriculture Department promote with MasAgro”.

Víctor Villalobos Arámbula, Mexico’s Secretary of Agriculture, said that the EAT-Lancet Commission report recommendations were very much in line with the strategic public policies that Mexico plans to implement in the coming years.

International Women’s Day 2019: Women in seed systems in Africa

The maize seed sector in eastern and southern Africa is male-dominated. Most seed companies operating in the region are owned and run by men. Access to land and financial capital can often be a constraint for women who are keen on investing in agriculture and agribusiness. However, there are women working in this sector, breaking social barriers, making a contribution to improving household nutrition and livelihoods by providing jobs and improved seed varieties.

The Gender team within the International Maize and Wheat Improvement Center’s (CIMMYT) Socioeconomics Program conducted interviews with women owners of seed companies in eastern and southern Africa. They shared information on their background, their motivation to start their businesses, what sets their companies apart from the competition, the innovative approaches they use to ensure smallholder farmers adopt improved seed varieties, the unique challenges they face as women in the seed sector and the potential for growth of their companies. The resulting stories will be published as a report in May 2019.

These women in leading roles serve as mentors and examples to both male and female employees. In honor of International Women’s Day, held March 8, 2019, CIMMYT would like to share some of their stories to recognize these women — and many others like them — and the important work they do in seed systems in Africa.

Sylvia Horemans started Kamano Seeds in April 2004 together with her late husband Desire Horemans. The company derives its name from a stream that runs through their farm in Mwinilinga, Zambia. Kamano means a stream that never dries, aptly describing the growth the company has enjoyed over the years, enabling it to capture 15 percent of the country’s seed market share.  Sylvia became the company’s Chief Executive Officer in 2016.

“The initial business was only to sell commercial products but we realized there was a high demand for seed so we decided to start our own seed business,” says Sylvia. “We work with cooperatives which identify ideal farmers to participate in seed production.”

The company takes pride in the growth they have witnessed in their contract workers. “Most farmers we started with [now] have 20 to 40 hectares. Some are businessmen and have opened agrodealer shops where they sell agricultural inputs,” Sylvia announced.

Kamano prides itself in improving the lives of women smallholders and involving women in decision-making structures. “We empower a lot of women in agriculture through our out-grower scheme,” says Sylvia. She makes a deliberate effort to recruit women farmers, ensuring they receive payment for their seeds. “We pay the women who did the work and not their husbands.”

Zubeda Mduruma, 65, is a plant breeder. She took to agriculture from a young age, as she enjoyed helping her parents in the family farm. After high school, Zubeda obtained a bachelor’s degree in Agriculture. Then she joined Tanzania’s national agriculture research system, working at the Ilonga Agricultural Research Institute (ARI-Ilonga) station. She then pursued her master’s in Plant Breeding and Biometry from Cornell University in the United Stations and obtained a doctorate in Plant Breeding at Sokoine University of Agriculture in Tanzania, while working and raising her family. “I wanted to be in research, so I could breed materials which would be superior than what farmers were using, because they were getting very low yields,” says Zubeda. In the 22 years she was at Ilonga, Zubeda was able to release 15 varieties.

Aminata Quality Seeds is a family business that was registered in 2008, owned by Zubeda, her husband and their four daughters. Aminata entered the seed market as an out-grower, producing seed for local companies for two years. The company started its own seed production in 2010, and the following year it was marketing improved varieties. “I decided to start a company along the Coast and impart my knowledge on improved technologies, so farmers can get quality crops for increased incomes,” says Zubeda.

Zubeda encourages more women to venture into the seed business. “To do any business, you have to have guts. It is not the money; it is the interest. When you have the interest, you will always look for ways on how to start your seed business.”

Grace Malindi, 67, started Mgom’mera in Malawi in 2014 with her sister Florence Kahumbe, who had experience in running agrodealer shops. Florence was key in setting up the business, particularly through engagement with agro-dealers, while Grace’s background in extension was valuable in understanding their market. Grace has a doctoral degree in Human and Community Development with a double minor in Gender and International Development and Agriculture Extension and Advisory from the University of Illinois Urbana-Champaign in the United States. Mgom’mera is a family-owned enterprise. Grace’s three children are involved in the business, serving as directors.

Mgom’mera distinguishes itself from other seed companies because of its focus on maize varieties that have additional nutritive value. The company uses the tagline “Creating seed demand from the table to the soil.” It educates farmers not only on how to plant the seed they sell, but also on how to prepare nutritious dishes with their harvest. The company stocks ZM623, a drought-tolerant open-pollinated variety, and Chitedze 2, a quality protein maize. In the 2019 maize season it will also sell MH39, a pro-vitamin A variety. In addition, they are looking forward to beginning quality protein maize hybrid production in the near future, having started the process of acquiring materials from CIMMYT.

Grace observes that women entrepreneurs are late entrants in seed business. “You need agility, flexibility and experience to run a seed business and with time you will improve,” says Grace, advising women who may be interested in venturing into this male-dominated business.

New publications: Gender and agricultural innovation in Oromia region, Ethiopia

Despite formal decentralization, agricultural services in Ethiopia are generally “top-down,” claim the authors of a recently published paper on gender and agricultural innovation. “Extension services,” they explain, “are supply-driven, with off-the-shelf technologies transferred to farmers without expectation of further adaptation.”

Drawing on GENNOVATE case studies from two wheat-growing communities in Ethiopia’s Oromia region, the authors examine how a small sample of women and men smallholders attempt to innovate with improved wheat seed, row planting, and the broad bed maker, introduced through the Ethiopian agricultural extension system. They also introduce the concept of tempered radicals, an analytic lens used to understand how individuals try to initiate change processes, and assess whether this can have validity in rural settings.

As the authors demonstrate through their literature review on cultural norms in the region, there are powerful institutional gender constraints to change processes, which can be punitive for women.

Ethiopian women smallholders are particularly disadvantaged because they have limited access to productive assets such as irrigation water, credit and extension services. Therefore, they find it harder to implement innovations. The study asserts that strategies to support innovators, and women innovators in particular, must be context-specific as well as gender-sensitive.

Policy forum in Mozambique recommends scaling sustainable agriculture practices

For many small farmers across sub-Saharan Africa, the crop yields their livelihoods depend on are affected by low-quality inputs and severe challenges like climate change, pests and diseases. Unsustainable farming practices like monocropping are impacting soil health and reducing the productivity of their farms.

Sustainable intensification practices based on conservation agriculture entail minimal soil disturbance, recycling crop plant matter to cover and replenish the soil, and diversified cropping patterns. These approaches maintain moisture, reduce erosion and curb nutrient loss. Farmers are encouraged and supported to intercrop maize with nitrogen-fixing legumes — such as beans, peas and groundnuts — which enrich the soil with key nutrients. Farmers are equally advised to cultivate their crops along with trees, instead of deforesting the land to create room for farming.

These practices result in higher incomes for farmers and better food and nutrition for families. Adopting conservation agriculture also improves farmers’ climate resilience. Combined with good agronomic practices, conservation agriculture for sustainable intensification can increase yields up to 38 percent.

Since 2010, the Sustainable Intensification of Maize and Legume Cropping Systems for Food Security in Eastern and Southern Africa (SIMLESA) project has promoted effective ways to produce more food while protecting the environment across Eastern and Southern Africa. In particular, the SIMLESA project aims at sustainably increasing the productivity of maize and legume systems in the region.

The SIMLESA project demonstrated the advantages of deploying low-carbon and low-cost mechanization adapted to smallholder farming: it addresses labor shortages at critical times like planting or weeding, boosting farmers’ productivity and yields. The SIMLESA project introduced mechanization in different phases: first improved manual tools like the jab planter, later draft power machinery innovations such as rippers, and finally motorized mechanization in the form of small four-wheel tractors.

From proof of concept to nation-wide adoption

In Mozambique, conservation agriculture-based sustainable intensification practices have significantly expanded: from 36 farmers in six villages in four districts in 2010, to over 190,000 farmers in more than 100 villages in nine districts by the end of 2018. This remarkable result was achieved in collaboration with partners such as the Mozambican Agricultural Research Institute (IIAM), extension workers, communities and private companies.

“Smallholder agriculture mechanization reduced the amount of labor required for one hectare of land preparation, from 31 days to just 2 hours. This enabled timely farming activities and a maize yield increase of about 170 kg per hectare, reflecting an extra 3-4 months of household food security,” said the national coordinator for SIMLESA in Mozambique, Domingos Dias.

Following its successes, SIMLESA and its partners have embarked on a series of meetings to discuss how to leverage public-private partnerships to expand conservation agriculture practices to other regions.

Throughout February and March 2019, a series of policy forums at sub-national and national levels will be held across the seven SIMLESA countries: Ethiopia, Kenya, Malawi, Mozambique, Rwanda, Tanzania and Uganda.

The first policy dialogue took place on February 7 in Chimoio, in Mozambique’s district of Manica. Key agriculture stakeholders attended, including representatives from CIMMYT, IIAM, the Ministry of Agriculture, as well as policy makers, private sector partners and international research institutes.

“We are delighted at SIMLESA’s unique strategy of involving multiple partners in implementing conservation agriculture for sustainable intensification practices. This has, over the years, allowed for faster dissemination of these practices and technologies in more locations in Mozambique, thereby increasing its reach to more farmers,” said Albertina Alage, Technical Director for Technology Transfer at IIAM. “Such policy forums are important to showcase the impact of conservation agriculture to policy makers to learn and sustain their support for scaling up conservation agriculture for sustainable intensification,” she added.

Forum participants called for better coordination between the public and the private sector to deliver appropriate machinery for use by smallholders in new areas. They recommended adequate support to enable farmers to better integrate livestock and a diverse cropping system, as well as continue with conservation agriculture trials and demonstration activities. Besides involving farmers, their associations and agro-dealer networks in scaling conservation agriculture initiatives, participants agreed to promote integrated pest and disease management protocols. This is considering the recent outbreak of the fall armyworm, which devasted crops in many countries across sub-Saharan Africa.

“The SIMLESA project is and will always be a reference point for our research institute and the Ministry of Agriculture in our country. The good progress of SIMLESA and the results of this forum will help to draw strategies for continuity of this program implemented by government and other programs with the aim to increase production and productivity of farmers,” Alage concluded.

The SIMLESA project is a science for development alliance, funded by the Australian Centre for International Agricultural Research (ACIAR) and led by the International Maize and Wheat Improvement Center (CIMMYT), in collaboration with national research institutes in Ethiopia, Kenya, Malawi, Mozambique and Tanzania.

Assessing the effectiveness of a “wheat holiday” for preventing blast in the lower Gangetic plains

Wheat blast — one of the world’s most devastating wheat diseases — is moving swiftly into new territory in South Asia.

In an attempt to curb the spread of this disease, policymakers in the region are considering a “wheat holiday” policy: banning wheat cultivation for a few years in targeted areas. Since wheat blast’s Magnaporthe oryzae pathotype triticum (MoT) fungus can survive on seeds for up to 22 months, the idea is to replace wheat with other crops, temporarily, to cause the spores to die. In India, which shares a border of more than 4,000 km with Bangladesh, the West Bengal state government has already instituted a two-year ban on wheat cultivation in two districts, as well as all border areas. In Bangladesh, the government is implementing the policy indirectly by discouraging wheat cultivation in the severely blast affected districts.

CIMMYT researchers recently published in two ex-ante studies to identify economically feasible alternative crops in Bangladesh and the bordering Indian state of West Bengal.

Alternative crops

The first step to ensuring that a ban does not threaten the food security and livelihoods of smallholder farmers, the authors assert, is to supply farmers with economically feasible alternative crops.

In Bangladesh, the authors examined the economic feasibility of seven crops as an alternative to wheat, first in the entire country, then in 42 districts vulnerable to blast, and finally in ten districts affected by wheat blast. Considering the cost of production and revenue per hectare, the study ruled out boro rice, chickpeas and potatoes as feasible alternatives to wheat due to their negative net return. In contrast, they found that cultivation of maize, lentils, onions, and garlic could be profitable.

The study in India looked at ten crops grown under similar conditions as wheat in the state of West Bengal, examining the economic viability of each. The authors conclude that growing maize, lentils, legumes such as chickpeas and urad bean, rapeseed, mustard and potatoes in place of wheat appears to be profitable, although they warn that more rigorous research and data are needed to confirm and support this transition.

Selecting alternative crops is no easy task. Crops offered to farmers to replace wheat must be appropriate for the agroecological zone and should not require additional investments for irrigation, inputs or storage facilities. Also, the extra production of labor-intensive and export-oriented crops, such as maize in India and potatoes in Bangladesh, may add costs or require new markets for export.

There is also the added worry that the MoT fungus could survive on one of these alternative crops, thus completely negating any benefit of the “wheat holiday.” The authors point out that the fungus has been reported to survive on maize.

A short-term solution?

In both studies, the authors discourage a “wheat holiday” policy as a holistic solution. However, they leave room for governments to pursue it on an interim and short-term basis.

In the case of Bangladesh, CIMMYT agricultural economist and lead author Khondoker Mottaleb  asserts that a “wheat holiday” would increase the country’s reliance on imports, especially in the face of rapidly increasing wheat demand and urbanization. A policy that results in complete dependence on wheat imports, he and his co-authors point out, may not be politically attractive or feasible. Also, the policy would be logistically challenging to implement. Finally, since the disease can potentially survive on other host plants, such as weeds and maize, it may not even work in the long run.

In the interim, the government of Bangladesh may still need to rely on the “wheat holiday” policy in the severely blast-affected districts. In these areas, they should encourage farmers to cultivate lentils, onions and garlic. In addition, in the short term, the government should make generic fungicides widely available at affordable prices and provide an early warning system as well as adequate information to help farmers effectively combat the disease and minimize its consequences.

In the case of West Bengal, India, similar implications apply, although the authors conclude that the “wheat holiday” policy could only work if Bangladesh has the same policy in its blast-affected border districts, which would involve potentially difficult and costly inter-country collaboration, coordination and logistics.

Actions for long-term success

The CIMMYT researchers urge the governments of India and Bangladesh, their counterparts in the region and international stakeholders to pursue long-term solutions, including developing a convenient diagnostic tool for wheat blast surveillance and a platform for open data and science to combat the fungus.

A promising development is the blast-resistant (and zinc-enriched) wheat variety BARI Gom 33 which the Bangladesh Agricultural Research Institute (BARI) released in 2017 with support from CIMMYT. However, it will take at least three to five years before it will be available to farmers throughout Bangladesh. The authors urged international donor agencies to speed up the multiplication process of this variety.

CIMMYT scientists in both studies close with an urgent plea for international financial and technical support for collaborative research on disease epidemiology and forecasting, and the development and dissemination of new wheat blast-tolerant and resistant varieties and complementary management practices — crucial steps to ensuring food security for more than a billion people in South Asia.

Wheat blast impacts

First officially reported in Brazil in 1985, where it eventually spread to 3 million hectares in South America and became the primary reason for limited wheat production in the region, wheat blast moved to Bangladesh in 2016. There it affected nearly 15,000 hectares of land in eight districts, reducing yield by as much as 51 percent in the affected fields.

Blast is devilish: directly striking the wheat ear, it can shrivel and deform the grain in less than a week from the first symptoms, leaving farmers no time to act. There are no widely available resistant varieties, and fungicides are expensive and provide only a partial defense. The disease, caused by the fungus Magnaporthe oryzae pathotype triticum (MoT), can spread through infected seeds as well as by spores that can travel long distances in the air.

South Asia has a long tradition of wheat consumption, especially in northwest India and Pakistan, and demand has been increasing rapidly across South Asia. It is the second major staple in Bangladesh and India and the principal staple food in Pakistan. Research indicates 17 percent of wheat area in Bangladesh, India, and Pakistan — representing nearly 7 million hectares – is vulnerable to the disease, threatening the food security of more than a billion people.

CIMMYT and its partners work to mitigate wheat blast through projects supported by U.S. Agency for International Development (USAID), the Bill & Melinda Gates Foundation, the Australian Centre for International Agricultural Research (ACIAR), the Indian Council for Agricultural Research (ICAR), the CGIAR Research Program on Wheat and the CGIAR Platform for Big Data in Agriculture.

Women’s equality crucial for Ethiopia’s agricultural productivity

The Government of Ethiopia recently announced an ambitious goal to reach wheat self-sufficiency by 2022, eliminating expensive wheat imports and increasing food security.

However, a new report based on a four-year research project on gender and productivity in Ethiopia’s wheat sector indicates that a lack of technical gender research capacity, a shortage of gender researchers and low implementation of gender-focused policies is hampering these efforts.

New partnership announced for sustainable maize production in Colombia

Palmira (Colombia), February 14, 2019 — AGROSAVIA, Colombia’s leading not-for-profit organization for agricultural research and technology transfer, the International Center for Tropical Agriculture (CIAT) and the International Maize and Wheat Improvement Center (CIMMYT) have signed a five-year agreement that aims to boost maize production.

The new project will develop maize varieties adapted to the country’s farming conditions, and will promote sustainable intensification technologies and practices among Colombian farmers.

“We should be able to release the first high-yielding maize variety for Colombia in three years”, said Bram Govaerts, CIMMYT’s director of Innovative Business Strategies and regional representative for the Americas.

To achieve this goal, CIMMYT will provide AGROSAVIA’s breeding program with two thousand advanced lines, developed by combining native maize from Colombia with conventionally improved varieties.

“At both institutions we believe that Colombia can increase production to close the big gap between domestic maize consumption and imports”, said AGROSAVIA’s Executive Director, Juan Lucas Restrepo. “With this agreement, we will have more powerful local capacities and once again a Colombian maize research program for Colombians”.

Although experts agree that Colombian farmers could potentially produce more than 10 tons per hectare, the country’s average yield is currently 3.6 tons per hectare.

“With this agreement, the sister CGIAR centers CIMMYT and CIAT give a first step in the implementation of Maize for Colombia, an ambitious plan that will sustainably increase Colombia’s maize output by building on the learnings and achievements of a successful project implemented in Mexico called MasAgro,” said Govaerts.

Colombia’s Minister of Agriculture and Rural Development, Andrés Valencia, CIAT’s Director General, Rubén Echeverría, Juan Lucas Restrepo, and Bram Govaerts participated in the launch ceremony for the new agreement, which was signed at CIAT’s headquarters.

Experts analyze food systems at EAT-Lancet Commission report launch in Ethiopia

Earlier this year, the EAT-Lancet Commission published a groundbreaking report linking healthy diets and sustainable food systems. It proposed scientific targets that meet both the Sustainable Development Goals (SDGs) and the Paris Agreement action plan to reduce carbon emissions. Since then, more than 20 launch events have been scheduled around the globe, including Addis Ababa, Ethiopia.

On February 7, the African Union hosted the EAT-Lancet Commission on healthy diets for sustainable food systems. Government officials, researchers and experts attended the “Food Systems Dialogue on Ethiopia” and developed a list of recommendations going forward. Some of these included at least 10 percent resource allocation to agriculture, the creation of functional and efficient internal markets for enhancing food distribution within the country, post-harvest loss reduction, and stronger collaboration between government and other stakeholders.

“The report has drawn the attention of policy makers, civil society and donors,” said Kindie Tesfaye Fantaye, a researcher and crop modeler at the International Maize and Wheat Improvement Center (CIMMYT). “The event was a good opportunity to create awareness on the chronic problems of stunting and malnutrition in Africa, and agriculture’s central role in contributing to effective solutions.”

Tesfaye Fantaye said CIMMYT’s work is well aligned with the report’s recommendations. In addition to research on sustainable intensification approaches that improve livelihoods while reducing the environmental footprint, CIMMYT explores ways to reduce postharvest losses and increase the nutritional quality of food through biofortification.

During a high-level side event, the commissioners indicated that the report is in-line with the different African Union policies and strategies, including the Malabo Declaration on Agriculture and Postharvest Losses, Agenda 2063 and Comprehensive Africa Agriculture Development Program (CAADP).

“The power of food is its connection. If we get it right, it brings us to a healthy people and a healthy planet,” said Gunhild Anker Stordalen, the founder and executive chair of EAT Foundation.

Precision planters boost maize yields in Pakistan

In the northwestern province of Pakistan, near the Afghan border, the International Maize and Wheat Improvement Center (CIMMYT) is helping connect farmers with precision planters to support higher maize yields and incomes. Maize is one of the most important cereals in Pakistan, but in the province of Khyber Pakhtunkhwa yields are significantly lower than the national average. The majority of maize farmers in this province have less than five acres of land and limited access to resources, including high-quality maize seed and mechanization.

Under the Agricultural Innovation Program (AIP) for Pakistan, CIMMYT introduced push row planters in 2016 to help farmers to get a uniform crop stand and save labor costs and time as compared to traditional planting practices. CIMMYT has since then partnered with Greenland Engineering to import tractor-operated precision maize planters. These precision planters allow farmers to plant two rows of maize in one pass and evenly distribute both seeds and fertilizer.

“Optimum planting density in combination with nutrient supply is key to getting the maximum maize yield,” says Muhammad Asim, a senior researcher with the Cereal Crops Research Institute (CCRI). “The precision planter helps farmers achieve this while also getting a uniform crop stand and uniform cobs.”

Jalees Ahmed, a smallholder maize farmer from the Nowshera district, Khyber Pakhtunkhwa, received a push row planter through CIMMYT’s AIP program. He used to hire six laborers to plant one acre of maize, but with the push row planter, Jalees only needs to hire one laborer and benefits from a more uniform crop.

Raham Dil, another farmer in the Mardan district, recently purchased a push row planter for his farm which he also rents to fellow farmers in the area.

Both Ahmed and Dil say these planters have made it easier to support their families financially. Interest in precision planters continues to grow.

Last fall, more than 80 farmers attended a field day in the Nowshera district where CIMMYT researchers demonstrated how to use the precision planter to sow maize. CIMMYT’s country representative for Pakistan, Imtiaz Muhammad, highlighted the importance of mechanized maize planting for farmers and CIMMYT’s commitment to improve maize-based system productivity in less developed regions of the country.

The Agricultural Innovation Program for Pakistan is led by CIMMYT and funded by USAID. This project seeks to increase productivity and incomes by testing and promoting modern practices for agriculture’s major sub-sectors in the country. 

Smallholder wheat production can cut Africa’s costly grain imports

International scientists are working with regional and national partners in sub-Saharan Africa to catalyze local wheat farming and help meet the rapidly rising regional demand for this crop.

The specialists are focusing on smallholder farmers in Rwanda and Zambia, offering them technical and institutional support, better links to markets, and the sharing of successful practices across regions and borders, as part of the project “Enhancing smallholder wheat productivity through sustainable intensification of wheat-based farming systems in Rwanda and Zambia.”

“Work started in 2016 and has included varietal selection, seed multiplication, and sharing of high-yielding, locally adapted, disease-resistant wheat varieties,” said Moti Jaleta, a socioeconomist at the International Maize and Wheat Improvement Center (CIMMYT) who leads the project. “Our knowledge and successes in smallholder wheat production and marketing will also be applicable in Madagascar, Mozambique, and Tanzania.”

Maize is by far the number-one food crop in sub-Saharan Africa but wheat consumption is increasing fast, driven in part by rapid urbanization and life-style changes. The region annually imports more than 15 million tons of wheat grain, worth some US$ 3.6 billion at current prices. Only Ethiopia, Kenya, and South Africa grow significant amounts of wheat and they are still net importers of the grain.

“Growing more wheat where it makes sense to do so can help safeguard food security for people who prefer wheat and reduce dependence on risky wheat grain markets,” Jaleta explained. “We’re working in areas where there’s biophysical potential for the crop in rain-fed farming, to increase domestic wheat production and productivity through use of improved varieties and cropping practices.”

In addition to the above, participants are supporting the region’s wheat production in diverse ways:

  • Recommendations to fine-tune smallholder wheat value chains and better serve diverse farmers.
  • Testing of yield-enhancing farming practices, such as bed-and-furrow systems that facilitate efficient sowing and better weed control.
  • Testing and promotion of small-scale mechanization, such as power tillers, to save labor and improve sowing and crop establishment.
  • Exploring use of hand-held light sensors to precisely calibrate nitrogen fertilizer dosages throughout the cropping season.

Innocent Habarurema, wheat breeder in the Rwanda Agriculture and Animal Resources Development Board (RAB), cited recent successes in the release of improved, disease resistant wheat varieties, as well as engaging smallholder farmers in seed multiplication and marketing to improve their access to quality seed of those varieties.

“The main challenge in wheat production is the short window of time between wheat seasons, which doesn’t allow complete drying of harvested plants for proper threshing, Habarurema explained. “Suitable machinery to dry and thresh the wheat would remove the drudgery of hand threshing and improve the quality of the grain, so that it fetches better prices in markets.”

Millers, like this one in Rwanda, play a key role in wheat value chains.

Critical wheat diseases in Zambia include spot blotch, a leaf disease caused by the fungus Cochliobolus sativus, and head blight caused by Fusarium spp., which can leave carcinogenic toxins in the grain, according to Batiseba Tembo, wheat breeder at the Zambian Agricultural Research Institute (ZARI).

“Developing and disseminating varieties resistant to these diseases is a priority in the wheat breeding program at Mt. Makulu Agricultural Research Center,” said Tembo. “We’re also promoting appropriate mechanization for smallholder farmers, to improve wheat production and reduce the enormous drudgery of preparing the soil with hand hoes.”

Participants in the project, which runs to 2020, met at Musanze, in Rwanda’s Northern Province, during February 5-7 to review progress and plan remaining activities, which include more widespread sharing of seed, improved practices, and other useful outcomes.

“There was interest in trying smallholder winter wheat production under irrigation in Zambia to reduce the disease effects normally experienced in rainfed cropping,” said Jaleta, adding that the costs and benefits of irrigation, which is rarely used in the region, need to be assessed.

Project participants may also include in selection trials wheat varieties that have been bred to contain enhanced grain levels of zinc, a key micronutrient missing in the diets of many rural Africa households.

“The project will also push for the fast-track release and seed multiplication of the best varieties, to get them into farmers’ hands as quickly as possible,” Jaleta said.

In addition to CIMMYT, RAB, and ZARI, implementing partners include the Center for Coordination of Agricultural Research and Development for Southern Africa (CCARDESA). Generous funding for the work comes from the International Fund for Agricultural Development (IFAD) and the CGIAR Research Program on Wheat.

BISA and PAU awarded for collaborative work on residue management

The Borlaug Institute for South Asia-Punjab Agricultural University (BISA-PAU) joint team recently received an award from the Indian Society for Agricultural Engineers (ISAE) in recognition of their work on rice residue management using the Super Straw Management System, also known as Super SMS.

Developed and recommended by researchers at BISA and PAU in 2016, the Super SMS is an attachment for self-propelled combine harvesters which offers an innovative solution to paddy residue management in rice-wheat systems.

The Punjab government  has made the use of the Super SMS mandatory for all combine harvesters in northwestern India.

The Super SMS gives farmers the ability to recycle residues on-site, reducing the need for residue burning and thereby reducing environmental pollution and improving soil health. Instead, the Super SMS helps to uniformly spread rice residue, which is essential for the efficient use of Happy Seeder technology and maintaining soil moisture in the field.

Harminder Singh Sidhu, a senior research engineer with the International Maize and Wheat Improvement Center (CIMMYT) working at BISA, stressed the need for more sustainable methods of dealing with residue. “Happy Seeder was found to be a very effective tool for direct sowing of wheat after paddy harvesting, using combine harvesters fitted with Super Straw Management System.”

BISA-PAU researchers received the ISAE Team Award 2018 at the 53rd Annual Convention of ISAE, held from January 28 to January 30, 2019, at Baranas Hindu University in Varanasi, Uttar Pradesh state.

The director general of the Indian Council of Agricultural Research (ICAR), Trilochan Mohapatra, presented the award, acknowledging it as “a real team award which is making a difference on the ground.”

The recipients acknowledged the role of local industry partner New Gurdeep Agro Industries for its contributions to promoting the adoption of this machinery. Within eight months of commercialization in the Indian state of Punjab, over 100 manufacturers had begun producing the Super SMS attachment. Currently, more than 5,000 combine harvesters are equipped with it.

Scaling to new heights in agriculture

How to scale? This question frequently comes up as projects look to expand and replicate results. In order to sustain enduring impacts for projects after their lifetime, agricultural programs are turning to scaling strategies. These strategies look beyond the numbers that are reached within a project and include sustainability and transformation beyond the project context. Methods and tools exist that help anticipate realistic and responsible scaling pathways.

The Scaling team at the International Maize and Wheat Improvement Center (CIMMYT), led by Lennart Woltering, drives the initiative to incorporate scaling principles into existing and developing projects to maximize impact.

Maria Boa recently joined the team as Scaling Coordinator. Last year Boa and Woltering participated in regional meetings on scaling in Morocco, Tunisia and Vietnam, which highlighted the need for better dissemination of information on how to approach scaling, in addition to its benefits.

Participants of the Tunisia workshop collaborate on a group exercise.

According to Boa, one of the key messages highlighted throughout these events was that in order for scaling to take hold and be integrated into projects, “…there needs to be a shift in mindset to accept that change is complex and that most projects only address a fraction of the problem.” This is essential in using scaling to effectively support long-term results.

At a workshop in Tunisia organized by ICARDA, IFAD and CIMMYT in November 2018, many participants expressed interest in scaling strategy tools, but were puzzled on how to integrate them into their specific projects. Many determined that they were stuck developing scaling strategies in an outdated framework, or one that strictly focused on using technological innovations. One participant admitted that she was skeptical of scaling perspectives because many did not lie in her field of expertise.

The November 2018 CCAFS SEA Conference on Scaling in Vietnam provided a platform for the sharing and learning of experiences in the scaling world. Some of the key messages from the event included the importance of scaling agricultural innovations taking place in complex systems of agricultural transformation, and the necessity of joint cooperation from all involved stakeholders and their openness to taking on challenges as a way to support sustainable system change.

According to Boa, scaling is a process that heavily relies on strategic collaboration for lasting impact. “Projects often don’t take into account how they’re a part of a larger chain of potential change,” she says.

Already recognized as a sustainable leader within scaling, CIMMYT is looking to strengthen scaling efforts in order to foster a more enduring impact within CIMMYT projects and beyond.

Currently, the Scaling team at CIMMYT is conducting research on the “science of scaling” as it continues to function as a “help desk,” providing support integrating scaling principles in proposals and projects. Its primary role is to consider a project’s scaling needs and guide the development of an informed strategy to leverage efforts and resources. Boa hopes that by integrating responsible scaling approaches early on, projects can better balance the trade-offs associated with change.

Success in scaling is measured by a project’s enduring impact. However, stakeholders need more experience and capacity to see programs through to their end and be willing to monitor them beyond that lifespan. CIMMYT is developing and collecting the tools to support stakeholders with these specific capacities.

Developing a scaling strategy can also bring additional benefits: a discussion about scaling opens the door for raising awareness and fostering actions among different stakeholders towards system change and sustainable impact.

City dwellers in Africa and Asia increasingly choose wheat, research shows

The developing world’s appetite for wheat is growing swiftly, driven in part by rising incomes, rapid urbanization and the expansion of families where both spouses work outside the house, according to a recent seminar by two international experts.

“Our research is picking up significant shifts in demand among cereals, including the increasing popularity of wheat in Asia and sub-Saharan Africa,” said Khondoker Mottaleb, socioeconomist for the International Maize and Wheat Improvement Center (CIMMYT), speaking at a seminar at the center on December 11, 2018.

In preliminary results of a study using household data from six countries in Asia and five in sub-Saharan Africa, Mottaleb and his associate, Fazleen Binti Abdul Fatah, senior lecturer at the University of Technology MARA, Malaysia, found that the households of both regions will eat more wheat by 2030, mainly in place of rice in Asia and of maize and other coarse grain cereals in Africa.

Speedy urbanization, higher incomes, population growth, and allied lifestyle changes are all driving this trend, said Fazleen. “Many urban women are working, so families are transitioning to bread and other convenient wheat-based foods and processed foods.”

A typical case according to Mottaleb is that of Bangladesh, a country whose population at 160 million is half that of the United States but with a geographical area equivalent to the US state of Ohio. The per capita GDP of Bangladesh grew from US$360 to US$1,516 during 2000-2017, and more than 35 percent of the country’s inhabitants now live in cities.

Meeting demand for wheat in Bangladesh

A 2018 paper by Mottaleb and fellow CIMMYT researchers shows that wheat consumption will increase substantially in Bangladesh by 2030 and the country needs to expand production or increase imports to meet the growing demand.

“The country purchases nearly 70 percent of its wheat at an annual cost near or exceeding US$1 billion, depending on yearly prices,” said Mottaleb. “Wheat prices are relatively low and wheat markets have been relatively stable, but if yields of a major wheat exporting country suddenly fall, say, from pest attacks or a drought, wheat markets would destabilize and prices would spike, as occurred in 2008 and 2011.”

In a 2018 study, the United Kingdom’s Agriculture and Horticulture Development Board (AHDB) cautioned that declining wheat cropping area worldwide and significant stockpiling by China — which holds nearly half the world’s wheat stocks but does not export any grain — were masking serious risk in global wheat markets.

A recent report ranked Bangladesh as the world’s fifth largest wheat importer. Since 2014-15 domestic wheat consumption there has increased by 57 percent from 4.9 million metric ton to 7.7 million metric tons. Last December, the Food and Agriculture Organization (FAO) of the United Nations forecast Bangladesh wheat import requirements of 6 million tons for this year — 34 percent above the previous five-year average following steady increases since 2012-13.

“The prevailing narrative has wealthier and more urban consumers shifting from basic foods to higher value foods, and this is doubtless occurring,” said Fazleen, “but our work shows a more nuanced scenario. In the traditional rice consuming economies in Asia, rural households are also eating more wheat, due to rapid dietary transformations.”

For Bangladesh, the researchers propose growing additional wheat on fallow and less-intensively-cropped land, as well as expanding the use of newer, high-yielding and climate-smart wheat varieties.

“Our work clearly shows the rising popularity of wheat across Asia and Africa,” said Mottaleb. “We urge international development agencies and policymakers to enhance wheat production in suitable areas, ensuring food security for the burgeoning number of people who prefer wheat and reducing dependence on risky wheat grain markets.”

In addition to the paper cited above, Mottaleb and colleagues have published recent studies on Bangladesh’s wheat production and consumption dynamics and changing food consumption patterns.

The authors thank the CGIAR Research Program on Wheat for its support for these studies.

New publications: Role of Modelling in International Crop Research

“Crop modelling has the potential to significantly contribute to global food and nutrition security,” claim the authors of a recently published paper on the role of modelling in international crop research.  “Millions of farmers, and the societies that depend on their production, are relying on us to step up to the plate.”

Among other uses, crop modelling allows for foresight analysis of agricultural systems under global change scenarios and the prediction of potential consequences of food system shocks. New technologies and conceptual breakthroughs have also allowed modelling to contribute to a better understanding of crop performance and yield gaps, improved predictions of pest outbreaks, more efficient irrigation systems and the optimization of planting dates.

While renewed interest in the topic has led in recent years to the development of collaborative initiatives such as the Agricultural Model Intercomparison and Improvement Project (AgMIP) and the CGIAR Platform for Big Data in Agriculture, further investment is needed in order to improve the collection of open access, easy-to-use data available for crop modelling purposes. Strong impact on a global scale will require a wide range of stakeholders – from academia to the private sector – to contribute to the development of large, multi-location datasets.

In “Role of Modelling in International Crop Research: Overview and Some Case Studies,” CGIAR researchers outline the history and basic principles of crop modelling, and describe major theoretical advances and their practical applications by international crop research centers. They also highlight the importance of agri-food systems, which they view as key to meeting global development challenges. “The renewed focus on the systems-level has created significant opportunities for modelers to participant in enhancing the impact of science on developments. However, a coherent approach based on principles of transparency, cooperation and innovation is essential to achieving this.”

The authors call for closer interdisciplinary collaboration to better serve the crop research and development communities through the provision of model-based recommendations which could range from government-level policy development to direct crop management support for resource-poor farmers.
