The International Maize and Wheat Improvement Center (CIMMYT) announced a new three-year public–private partnership with the German development agency GIZ and the beverage company Grupo Modelo (AB InBev) to recharge aquifers and encourage water-conserving farming practices in key Mexican states.

The partnership, launched today, aims to contribute to a more sustainable use of water in agriculture. The project will promote sustainable farming and financing for efficient irrigation systems in the states of Hidalgo and Zacatecas, where Grupo Modelo operates. CIMMYT’s goal is to facilitate the adoption of sustainable intensification practices on more than 4,000 hectares over the next three years, to reduce the water footprint of participant farmers.

Mexico is at a high risk of facing a water crisis in the next few years, according to the World Resources Institute. The country needs to urgently begin reducing its use of available surface and ground water supplies if it is to avert the looming crisis.

Farming accounts for nearly 76% of Mexico’s annual water consumption, as estimated by Mexico’s Water Commission (CONAGUA). Farmers, therefore, have a key role to play in a more sustainable use of this valuable natural resource.

“We need to take care of the ecosystem and mitigate agriculture’s impact on the environment to address climate change by achieving more sustainable agri-food systems,” said Bram Govaerts, chief operating officer, deputy director general of research a.i. and director of the Integrated Development program at CIMMYT.

The project, called Aguas Firmes (Spanish for “Firm Waters”), also seeks to recharge two of Mexico’s most exploited aquifers, by restoring forests and building green infrastructure.

“Our priority is water, which is the basis of our business but, above all, the substance of life,” said Cassiano De Stefano, chair of Grupo Modelo, one of the Mexico’s leading beer companies. “We’ve decided to lead by example by investing considerably in restoring two aquifers that are essential to Zacatecas and Hidalgo’s development.”

The German development agency GIZ, one of CIMMYT’s top funders, is also investing in this alliance that will benefit 46,000 farmers in Hidalgo and 700,000 farmers in Zacatecas.

“We are very proud of this alliance for sustainable development that addresses a substantial problem in the region and strengthens our work on biodiversity conservation and sustainable use of natural resources in Mexico,” said Paulina Campos, Biodiversity director at GIZ Mexico.

CIMMYT undertakes participatory agricultural research activities with local farmers to collaboratively develop and implement sustainable farming practices and technologies that help reduce water consumption in grain production by up to 30%.

Many birds with one stone

In Ethiopia, farming systems rely heavily on animal and human power, reducing productivity and efficiency. In recent years, the government and development partners have made significant efforts to modernize agriculture.

In 2013, CIMMYT introduced one-axel multipurpose tractors in various districts of Amhara, Oromia, South and Tigray regions. This new technology has helped to improve farmers’ lives and phase out outdated farming practices. Farmers have reduced drudgery, improved productivity and gained higher profits. This short video shows the impacts the two-wheel tractor brough to smallholder farmers in Ethiopia.

Financial support for this initiative came from the German development agency GIZ, USAID and the Australian government.

Breaking Ground: Natalia Palacios gets the most out of maize

It’s often joked that specialists learn more and more about less and less until they know everything about nothing, while for generalists it’s just the opposite.

In the case of Natalia Palacios, neither applies. She may have the word specialist in her title — she is a maize quality specialist at the International Maize and Wheat Improvement Center (CIMMYT) — but throughout her career she has had to learn more and more about a growing range of topics.

As leader of the Nutrition Chapter of the Integrated Development Program and head of the Maize Quality Laboratory, Palacios’ job is to coordinate CIMMYT’s efforts to ensure that maize-based agri-food systems in low- and middle-income countries are as healthy and nutritious as possible. The scope of this work spans the breadth of maize-based agri-food systems — from seed to supper.

“What ultimately matters for human health and nutrition is the nutritional quality of the final product,” says Palacios. “High quality, nutritious grain is an important part of the puzzle, but so are the nutritional effects of various post-harvest storage, processing, and cooking techniques.”

Seeing the forest and the trees

Originally from Bogota, Colombia, Palacios studied microbiology at the Universidad de los Andes before pursuing a PhD in plant biology at the University of East Anglia and the John Innes Centre in the United Kingdom.

“I had the opportunity to work as research assistant at the International Center for Tropical Agriculture (CIAT) in Cali, Colombia,” she explains. “The exposure to interdisciplinary and international teams working for agricultural development and the leadership of my boss at that time, Joe Tohme, not only helped convince me to pursue post graduate studies in plant biology, they fostered an excitement around the real-world applications of scientific research.”

When she joined CIMMYT in 2005, Palacios worked on maize biofortification, supporting efforts to breed maize varieties rich in provitamin A and zinc. With time, she found her attention shifting towards the effect of food processing on the nutritional quality of maize-based food products, as well as to the importance of maize safety. For example, for a recent project, Palacios and her team have been analyzing the effect of a traditional thermal alkaline maize treatment known as nixtamalization on the physical composition of the grain and the nutritional quality of end products. Because of its important benefits, they are promoting this ancient technique in other geographies.

For Palacios, shifts such at this are completely in keeping with the overall goal of her work. “The main challenge we face as agricultural researchers is contributing to a nutritious, affordable diet produced within planetary boundaries,” she says. “Tackling any part of this challenge requires us to communicate between disciplines, to look at agri-food systems as a whole, and to link production and consumption.”

At the same time, for Palacios, the beauty of her work lies in going deep into a specific research question before bringing her focus back to the big picture. This movement between the specific and the general keeps her motivated, generates new questions and avenues of research, and keeps her from falling into silver-bullet thinking.

For example, her work on provitamin A biofortified maize led her to ask questions about how much of the vitamin reached consumers depending on how the grain was stored and handled. The vitamin is prone to degradation through oxidation. This led to storage and processing recommendations meant to maximize the crop’s nutritional value, including storing provitamin A maize as grain and milling it as late as possible before consumption. Researchers also worked to identify germplasm with more stable provitamin A carotenoids to be used in the breeding program.

In one study, Palacios and her coauthors found that feeding biofortified maize to hens increased the provitamin A value of their eggs, suggesting that for rural households the nutritional benefits of the improved grain could be spread out across different foodstuffs.

Bringing it all together

In a paper published last spring, Palacios and her co-authors bring together the insights of these various avenues of research into one comprehensive review. The point, Palacios explains “was to identify opportunities to exploit the nutritional benefits of maize — a grain largely consumed in Africa, Latin America and some parts of Asia as important part of a diet — from understanding how to leverage the its genetic diversity for the development of more nutritious varieties to mapping all the different parts of the food system where nutritional gains can be made.”

The paper encompasses sections on the biochemistry of maize, maize breeding, maize-based foodways and culture, and traditional agronomic practices like milpa intercropping. It exemplifies Palacios’ interdisciplinary approach and her commitment to exploring multiple, interconnected pathways towards more nutritious maize agri-food systems.

As CGIAR’s 2030 Research and Innovation Strategy makes clear with its emphasis on the need for a systems-level transformation of food, land and water systems, this approach is timely and much needed.

In Palacios’ words: “Food security, nutrition and food safety are inextricably linked, and we must address them from the field to the plate and in a sustainable way.”

 

On-farm nitrogen management practices have global reverberations

An international team of scientists has strengthened our understanding of how better fertilizer management could help minimize nitrous oxide (N2O) emissions while still achieving high crop yields in the new publication: Meta-analysis of yield and nitrous oxide outcomes for nitrogen management in agriculture. This research was conducted through a meta-analysis, where the results of multiple scientific studies were statistically combined.

To meet the world’s growing demand for food, farmers need fertile soil. Nitrogen, an essential element in plant fertilizer, can have extremely deleterious effects on the environment when not managed effectively. Numerous studies have confirmed that improving nitrogen use in agriculture is key to securing a food secure future and environmental sustainability.

“Society needs nuanced strategies based upon tailored nutrient management approaches that keep nitrogen balances within safe limits,” said Tai M Maaz, researcher at University of Hawaii at Manoa and lead author of the study.

When farmers apply nitrogen fertilizer to their crop, typically only 30-40% of it is taken up by the plant and the rest is lost the the environment. One byproduct is  nitrous oxide (N2O), one of the most potent greenhouse gases in the atmosphere. Global agriculture is a major contributor of greenhouse gas emissions, especially those derived from nitrous oxide emissions.

Although farmers are now commonly told to practice fertilizer rate reduction, or simply put, to apply less fertilizer, there are cases where that strategy is either not possible or not advisable.

Alternative predictors of emissions

The study found that output indicators such as partial nitrogen balance (PNB), an indicator for the amount of nitrogen prone to loss, and partial factor productivity (PFP), a measure of input-use efficiency, predicted nitrous oxide emissions as well as or better than the application rate alone. This means that in some cases, where nitrogen rate reduction is not possible, nitrous oxide emission can still be reduced by increasing yield through implementation of improved fertilizer management practices, such as the “4Rs:” right source, right timing, right placement and right application rate.

Tek B Sapkota, climate scientist at the International Maize and Wheat Improvement Center (CIMMYT) and co-author of the study, emphasized that “rate reduction is still important in the cropping systems where the current level of nitrogen application is excessively high. But, when comparing the systems at the same nitrogen application rates, nitrous oxide emission can be reduced by increasing yield.”

“The 4R nutrient management practices must be tailored to specific regions to help close yield gaps and maintain environmental sustainability: the win-win scenario. The future will require public and private institutions working together to disseminate such nutrient management information for specific cropping systems in specific geographies,” said Sapkota, who is also a review editor of the Intergovernmental Panel on Climate Change (IPCC) sixth assessment report.

The article was a collaborative effort from the International Maize and Wheat Improvement Center (CIMMYT), the University of Hawaii, the Environmental Defense Fund, Plant Nutrition Canada and the African Plant Nutrition Institute. It was funded by the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS).

World Health Day 2021

Health has certainly been in the spotlight over the past year. And how could it not be?

The ongoing COVID-19 pandemic has thrown into sharp relief the fact that many groups across the world struggle to make ends meet with little daily income, have poorer housing conditions and education, fewer employment opportunities, and have little or no access to safe environments, clean water and air, food security and health services.

In light of this, the World Health Organization (WHO) is calling on leaders worldwide to ensure that everyone has living and working conditions that are conducive to good health. For many the focus will, understandably, be on access to quality health care services. But there are myriad other factors that influence our ability to lead healthy lives — from how we care for our soil, to what we eat and the air we breathe.

Joining this year’s World Health Day campaign, the International Maize and Wheat Improvement Center (CIMMYT) is highlighting five areas where it pays to think about health, and the solutions we can use to help build a healthier world for everyone.

It starts with soil

Crop yields fall dramatically when soil conditions aren’t right, but digital nutrient management tools providing tailored fertilizer recommendations can boost farmers’ profits and productivity while reducing emissions.

Robust germplasm

How do we ensure that germplasm reserves are not potential vectors of pest and disease transmission? The second instalment in the CGIAR International Year of Plant Health Webinar Series tackles the often-overlooked issue of germplasm health.

Quality feed

By growing maize simultaneously for both human consumption and quality animal feed, farmers can get the most out of their crops and conserve natural resources like land and water.

Feeding communities

The traditional milpa intercrop — in which maize is grown together with beans, squash or other vegetable crops — can furnish a vital supply of food and nutrients for marginalized, resource-poor communities in the Americas.

A healthy planet

Compared to conventional tillage practices, sowing wheat directly into just-harvested rice fields without burning or removing straw or other residues can reduce severe air pollution while lessening irrigation needs.

Nepal launches digital soil map

A new digital soil map for Nepal provides access to location-specific information on soil properties for any province, district, municipality or a particular area of interest. The interactive map provides information that will be useful to make new crop- and site-specific fertilizer recommendations for the country.

Produced by the International Maize and Wheat Improvement Center (CIMMYT), in collaboration with Nepal Agricultural Research Council’s (NARC) National Soil Science Research Center (NSSRC), this is the first publicly available soil map in South Asia that covers the entire country.

The Prime Minister of Nepal, K.P. Sharma Oli, officially launched the digital soil map at an event on February 24, 2021. Oli highlighted the benefits the map would bring to support soil fertility management in the digital era in Nepal. He emphasized its sustainability and intended use, mainly by farmers.

CIMMYT and NSSRC made a live demonstration of the digital soil map. They also developed and distributed an informative booklet that gives an overview of the map’s major features, operation guidelines, benefits, management and long-term plans.

The launch event was led by the Ministry of Agriculture and Livestock Development and organized in coordination with NARC, as part of the Nepal Seed and Fertilizer (NSAF) project, implemented by CIMMYT. More than 200 people participated in the event, including government officials, policymakers, scientists, professors, development partner representatives, private sector partners and journalists. The event was also livestreamed.

Better decisions

Immediately after the launch of the digital soil map, its CPU usage grew up to 94%. Two days after the launch, 64 new accounts had been created, who downloaded different soil properties data in raster format for use in maps and models.

The new online resource was prepared using soil information from 23,273 soil samples collected from the National Land Use Project, Central Agricultural Laboratory and Nepal Agricultural Research Council. The samples were collected from 56 districts covering seven provinces. These soil properties were combined with environmental covariates (soil forming factors) derived from satellite data and spatial predictions of soil properties were generated using advanced machine learning tools and methods.

The platform is hosted and managed by NARC, who will update the database periodically to ensure its effective management, accuracy and use by local government and relevant stakeholders. The first version of the map was finalized and validated through a workshop organized by NSSRC among different stakeholders, including retired soil scientists and university professors.

“The ministry can use the map to make more efficient management decisions on import, distribution and recommendation of appropriate fertilizer types, including blended fertilizers. The same information will also support provincial governments to select suitable crops and design extension programs for improving soil health,” said Padma Kumari Aryal, Minister of Agriculture and Livestock Development, who chaired the event. “The private sector can utilize the acquired soil information to build interactive and user-friendly mobile apps that can provide soil properties and fertilizer-related information to farmers as part of commercial agri-advisory extension services,” she said.

“These soil maps will not only help to increase crop yields, but also the nutritional value of these crops, which in return will help solve problems of public health such as zinc deficiency in Nepal’s population,” explained Ivan Ortiz-Monasterio, principal scientist at CIMMYT, in a video message.

Yogendra Kumar Karki, secretary of the Ministry of Agriculture and Livestock Development, presented the program objectives and Deepak Bhandari, executive director of NARC, talked about the implementation of the map and its sustainability. Special remarks were also delivered by USAID Nepal’s mission director, the secretary of Livestock, scientists and professors from Tribhuwan University, the International Fertilizer Development Center (IFDC) and the International Centre for Integrated Mountain Development (ICIMOD).

Benefits of digital soil mapping

Soil properties affect crop yield and production. In Nepal, access to soil testing facilities is rather scarce, making it difficult for farmers to know the fertilizer requirement of their land. The absence of a well-developed soil information system and soil fertility maps has been lacking for decades, leading to inadequate strategies for soil fertility and fertilizer management to improve crop productivity. Similarly, existing blanket-type fertilizer recommendations lead to imbalanced application of plant nutrients and fertilizers by farmers, which also negatively affects crop productivity and soil health.

This is where digital soil mapping comes in handy. It allows users to identify a domain with similar soil properties and soil fertility status. The digital platform provides access to domain-specific information on soil properties including soil texture, soil pH, organic matter, nitrogen, available phosphorus and potassium, and micronutrients such as zinc and boron across Nepal’s arable land.

Farmers and extension agents will be able to estimate the total amount of fertilizer required for a particular domain or season. As a decision-support tool, policy makers and provincial government can design and implement programs for improving soil fertility and increasing crop productivity. The map also allows users to identify areas with deficient plant nutrients and provide site-specific fertilizer formulations; for example, determining the right type of blended fertilizers required for balanced fertilization programs. Academics can also obtain periodic updates from these soil maps and use it as a resource while teaching their students.

As digital soil mapping advances, NSSRC will work towards institutionalizing the platform, building awareness at the province and local levels, validating the map, and establishing a national soil information system for the country.

Nepal’s digital soil map is readily accessible on the NSSRC web portal:

What is nixtamalization?

For centuries, people across Mexico and Central America have been using a traditional method, known as nixtamalization, to process their maize.

Now carried out both at household and industrial levels, this technique offers a range of nutritional and processing benefits. It could easily be adopted by farmers and consumers in other parts of the world.

What is nixtamalization?

Nixtamalization is a traditional maize preparation process in which dried kernels are cooked and steeped in an alkaline solution, usually water and food-grade lime (calcium hydroxide).

After that, the maize is drained and rinsed to remove the outer kernel cover (pericarp) and milled to produce dough that forms the base of numerous food products, including tortillas and tamales.

How does it work?

Key steps of the traditional nixtamalization process. (Graphic: Nancy Valtierra/CIMMYT)

What happens when maize kernels are nixtamalized?

The cooking (heat treatment) and steeping in the alkaline solution induce changes in the kernel structure, chemical composition, functional properties and nutritional value.

For example, the removal of the pericarp leads to a reduction in soluble fiber, while the lime cooking process leads to an increase in calcium content. The process also leads to partial starch gelatinization, partial protein denaturation — in which proteins present in the kernel become insoluble — and a partial decrease in phytic acid.

What are the benefits of processing maize in this way?

In addition to altering the smell, flavor and color of maize products, nixtamalization provides several nutritional benefits including:

  • Increased bioavailability of vitamin B3 niacin, which reduces the risk of pellagra disease
  • Increased calcium intake, due to its absorption by the kernels during the steeping process
  • Increased resistant starch content in food products, which serves as a source of dietary fiber
  • Significantly reduced presence of mycotoxins such as fumonisins and aflatoxins
  • Increased bioavailability of iron, which decreases the risk of anemia

These nutritional and health benefits are especially important in areas where maize is the dietary staple and the risk of aflatoxins is high, as removal of the pericarp is thought to help reduce aflatoxin contamination levels in maize kernels by up to 60% when a load is not highly contaminated.

Additionally, nixtamalization helps to control microbiological activity and thus increases the shelf life of processed maize food products, which generates income and market opportunities for agricultural communities in non-industrialized areas.

Where did the practice originate?

The word itself comes from the Aztec language Nahuatl, in which the word nextli means ashes and tamali means unformed maize dough.

Populations in Mexico and Central America have used this traditional maize processing method for centuries. Although heat treatments and soaking periods may vary between communities, the overall process remains largely unchanged.

Today nixtamalized flour is also produced industrially and it is estimated that more than 300 food products commonly consumed in Mexico alone are derived from nixtamalized maize.

Can farmers and consumers in other regions benefit from nixtamalization?

Nixtamalization can certainly be adapted and adopted by all consumers of maize, bringing nutritional benefits particularly to those living in areas with low dietary diversity.

Additionally, the partial removal of the pericarp can contribute to reduced intake of mycotoxins. Aflatoxin contamination is a problem in maize producing regions across the world, with countries as diverse as China, Guatemala and Kenya all suffering heavy maize production losses as a result. While training farmers in grain drying and storage techniques has a significant impact on reducing post-harvest losses, nixtamalization technology could also have the potential to prevent toxin contamination and significantly increase food safety when used appropriately.

If adapted, modern nixtamalization technology could also help increase the diversity of uses for maize in food products that combine other food sources like vegetables.

Experts point ways to better crops and farmer incomes

The first One Earth Root and Soil Health Forum took place on March 1, 2021. Over 800 people attended to discuss how to unlock the potential of better soil and root health to help transform food systems. The Forum brought together experts from farming, international organizations, NGOs, academia and the public and private sectors. Together they called for collective action in science and technology targeting the early stages of plant growth.

The main emphasis this year was on Africa, which has around 60% of the world’s uncultivated arable land. However, parallel workshops focusing on Turkey, the Middle East, Sub-Saharan Africa and South Africa enabled tailored discussions in regional languages. Plenary keynote speakers were Erik Fyrwald (Syngenta Group CEO and Chairman of the Syngenta Foundation for Sustainable Agriculture) and Dr Ismahane Elouafi (Chief Scientist at the UN Food and Agriculture Organization).

Erik Fyrwald underlined that “everything starts with soil. It is the foundation of productive farming practices – with healthy soil, you can have healthy plants, healthy people and a healthy planet. By acting on soil health through regenerative agriculture practices, we are acting on climate change, biodiversity loss and food security, as well as improving farmer livelihoods. The One Earth Soil and Root Health Forum helps an international community shift towards achieving this – together.”

Dr Ismahane Elouafi noted that “healthy soils are the foundation for agriculture, as they provide 95% of our food. Soils also provide fuel, fiber and medical products, and play a key role in the carbon cycle, storing and filtering water, and improving resilience to floods and droughts.”

Speaking on the opening panel, Michael Misiko, Africa Agriculture Director of The Nature Conservancy, noted that “climate change is inseparable from the life and health of our soils and the roots that must thrive within them.”

CIMMYT senior scientist and country representative for Turkey, Abdelfattah Dababat, underlining the importance of awareness raising action. “Growers basically do not recognize soil/root health to be a problem. Most of them are not aware of the root rot diseases and soil health issues in their fields, affecting their yield. This is why the term “hidden enemy” applies perfectly. Root and soil health management is therefore, not practiced and those yield losses are simply accepted.”

Speakers also underlined the link between soil and root health and the long-term economic productivity and the welfare of societies. Other points raised included technologies measuring soil health and their role in enabling informed decision-making by farmers and scientists. The importance of empowering smallholders and enabling access to modern technologies was also underlined as was the importance of public-private sector collaboration in achieving this.

The different parallel sessions covered i) solutions for soil borne diseases in protecting and enhancing root health, ii) supporting smallholder farmers to improve the health and fertility of their soils and the opportunities for public and private sectors to engage, iii) no tillage technologies and seed treatment for soil and root health and iv) the state of nematode soil pest pressures. The negative impact of conventional tillage systems include soil erosion and carbon emissions. The importance therefore of no tillage technologies was analyzed.

Health underfoot: why roots and soil are important

Around 95% of the food we eat grows in the earth. However, more than one-third of the world’s soils are degraded; without rapid action, this figure could rise to 90% by 2050. Soil erosion decreases the water, nutrients and root-space available to plants.  Healthy roots enable better use of nutrients and water. They help produce more shoots and leaves from each seed, enabling farmers to produce more food and soil to capture more carbon. Healthy roots also help tackle soil erosion. Soil and root health help mitigate climate change. More carbon already resides in soil than in the atmosphere and all plant life combined. Studies show that there are 2,500 billion tons of carbon in soil, compared with 800 billion tons in the atmosphere and 560 billion tons in plant and animal life. Healthier soil can store even more. Healthy plants with good roots capture further carbon from the atmosphere.

A knowledge revolution

The key to transforming food production systems globally lies in knowledge management processes, according to a team of researchers from the International Maize and Wheat Improvement Center (CIMMYT).

The challenge is to combine traditional knowledge with state-of-the-art scientific research: to meet regional needs for improvement in farming systems with knowledge networks fostering innovative practices and technologies that increase yields and profits sustainably.

A group of CIMMYT researchers led by Andrea Gardeazábal, Information and Communications Technology for Agriculture Monitoring and Evaluation Manager, recently published a proposal for a new knowledge management framework for agri-food innovation systems: Agricultural Knowledge Management for Innovation (AKM4I).

“We are proposing a knowledge management framework for agricultural innovation that addresses the need for more inclusive and environmentally sustainable food production systems that are able to provide farmers and consumers with affordable and healthy diets within planetary boundaries,” Gardeazábal said.

The AKM4I framework was designed to help agricultural development practitioners understand how farming skills and abilities are developed, tested and disseminated to improve farming systems in real-life conditions.

Following systems theory principles, the model empirically describes how information is created, acquired, stored, analyzed, integrated and shared to advance farming knowledge and produce innovative outcomes that effectively contribute to: collaboratively building local capacities for developing joint problem-solving abilities and integrated-knowledge solutions; empowering farmers with site-specific knowledge; co-creating technology and conducting participatory community-based research; and bridging innovation barriers to drive institutional change.

Knowledge access for systems transformation

The framework builds on CIMMYT’s learnings from MasAgro, a bilateral project with Mexico that relies on participatory research and knowledge and technology development networks for sustainable maize and wheat production systems.

This CIMMYT project was recently acknowledged with the 2020 Innovative Applications in Analytics Award for developing groundbreaking monitoring, evaluation, accountability and learning (MEAL) systems and tools for publicly funded researchers and field technicians who advise more than 150,000 farmers in Mexico.

“Through the outlined principles and processes, the AKM4I framework can assist in closing the cycle of continually re-creating knowledge, evaluating and iterating upon innovations, building coalitions to democratize knowledge access and utilization, and using MEAL to facilitate course-correction of all stages of knowledge management,” concludes the study.

Bram Govaerts, CIMMYT Chief Operating Officer, Deputy Director General for Research and Integrated Development Program Director, believes the AKM4I framework should be the cornerstone of agri-food systems transformation, including the current reformation of CGIAR’s partnerships, knowledge, assets, and global presence.

“The MasAgro hub and knowledge management model will become the operational model of many regional initiatives of CGIAR,” Govaerts said.

Development of Smart Innovation through Research in Agriculture (DeSIRA)

The overall objective of the 5-year EU-funded DeSIRA action, led by the International Potato Center (CIP), is to improve climate change adaptation of agricultural and food systems in Malawi through research and uptake of integrated technological innovations.

CIMMYT’s role is focused on the following project outputs:

  • Identify and develop integrated technology options that effectively provide management options to contribute to reducing risks and increasing resilience and productivity of the smallholder farmers’ agrifood systems in Malawi. Towards this objective, CIMMYT will evaluate drought-tolerant and nutritious maize varieties under conservation agriculture and conventional practices, and assess the overall productivity gains from agronomic and germplasm improvements versus current farming practices.
  • Develop, test and promote robust integrated pest and disease management strategies to predict, monitor and control existing and emerging biotic threats to agriculture while minimizing risks to farmers’ health and damage to the environment. Towards this objective, CIMMYT will evaluate the effect of striga on maize performance under conservation agriculture and conventional practices; evaluate farmer methods and other alternatives to chemical sprays for the control of fall armyworm; and study the effect of time of planting for controlling fall armyworm.

Power steering

Protected from the harsh midday sun with a hat, Pramila Mondal pushes behind the roaring engine of a two-wheel tractor. She cultivates a small plot of land with her husband in the small village of Bara Kanaibila, in the Rajbari district of Bangladesh, near the capital Dhaka.

Using this machine, she also provides planting services to farmers who need to sow wheat, maize, mungbean, mustard and jute, earning her between $600 and $960 in each planting season.

Mondal and her husband first heard about this technology five years ago, when they attended an event to promote agricultural mechanization, organized by the International Maize and Wheat Improvement Center (CIMMYT). After seeing a demonstration, they were convinced that the power-tiller-operated seeder could form the basis for a business.

Ultimately, Mondal bought the machine. She got training on how to operate and maintain it, as part of the Cereal Systems Initiative for South Asia – Mechanization Irrigation and Mechanization Extension Activity (CSISA-MI and CSISA-MEA) project, supported by USAID through Feed the Future.

Let’s get it started

Mondal became the only woman in her area who could operate a seeder of this type, making her locally famous. After seeing the results of her business, others followed suit.

Eight more women in her area expressed interest in operating power-tiller-operated seeders and also went on to become service providers.

They all faced a similar problem: power tillers are hard to start. Pulling the starting rope or turning the hand crank requires a lot of strength.

The CSISA-MEA project team worked with a local engineering company to introduce a self-starting mechanism for power tiller engines. Since then, starting diesel engines is no longer a problem for women like Mondal.

Glee for the tillerwoman

Almost all of the 11 million hectares of rice planted every year in Bangladesh are transplanted by hand. It is becoming increasingly difficult to find people willing to do this type of backbreaking work. New machines are being introduced that transplant rice mechanically, but they require rice seedling to be raised in seedling mats.

As this new service is required, Mondal jumped at the opportunity. With support from CIMMYT through the CSISA-MEA project, she is now raising seedlings for this new type of rice transplanters.

CIMMYT facilitated training for machinery service providers on mat type seedling production, in partnership with private companies. Mondal and other women who were also trained produced enough seedlings to plant 3.2 hectares of land with a rice transplanter they hired from a local owner.

Mondal and her husband now have big dreams. They intend to buy a rice transplanter and a combine harvester.

“With our effort we can make these changes, but a little support can make big difference, which the CSISA-MEA project did,” she said.
