Policy brief highlights opportunities to promote balanced nutrient management in South Asia

Written by Matthew O'Leary on December 17, 2019. Posted in Publications.

Over the last few decades, deteriorating soil fertility has been linked to decreasing agricultural yields in South Asia, a region marked by inequities in food and nutritional security.

As the demand for fertilizers grows, researchers are working with government and businesses to promote balanced nutrient management and the appropriate use of organic amendments among smallholder farmers. The Cereal Systems Initiative for South Asia (CSISA) has published a new policy brief outlining opportunities for innovation in the region.

Like all living organisms, crops need access to the right amount of nutrients for optimal growth. Plants get nutrients — like nitrogen, phosphorus, and potassium, in addition to other crucially important micronutrients — from soils and carbon, hydrogen, oxygen from the air and water. When existing soil nutrients are not sufficient to sustain good crop yields, additional nutrients must be added through fertilizers or manures, compost or crop residues. When this is not done, farmers effectively mine the soil of fertility, producing short-term gains, but undermining long-term sustainability.

Nutrient management involves using crop nutrients as efficiently as possible to improve productivity while reducing costs for farmers, and also protecting the environment by limiting greenhouse gas emissions and water quality contamination. The key behind nutrient management is appropriately balancing soil nutrient inputs — which can be enhanced when combined with appropriate soil organic matter management — with crop requirements. When the right quantities are applied at the right times, added nutrients help crops yields flourish. On the other hand, applying too little will limit yield and applying too much can harm the environment, while also compromising farmers’ ability to feed themselves or turn profits from the crops they grow.

Smallholder farmers in South Asia commonly practice poor nutrition management with a heavy reliance on nitrogenous fertilizer and a lack of balanced inputs and micronutrients. Declining soil fertility, improperly designed policy and nutrient management guidelines, and weak fertilizer marketing and distribution problems are among the reasons farmers fail to improve fertility on their farms. This is why it is imperative to support efforts to improve soil organic matter management and foster innovation in the fertilizer industry, and find innovative ways to target farmers, provide extension services and communicate messages on cost-effective and more sustainable strategies for matching high yields with appropriate nutrient management.

Cross-country learning reveals opportunities for improved nutrient management. The policy brief is based on outcomes from a cross-country dialogue facilitated by CSISA earlier this year in Kathmandu. The meeting saw researchers, government and business stakeholders from Bangladesh, India, Nepal, and Sri Lanka discuss challenges and opportunities to improving farmer knowledge and access to sufficient nutrients. Several key outcomes for policy makers and representatives of the agricultural development sector were identified during the workshop, and are included in the brief.

Extension services as an effective way to encourage a more balanced use of fertilizers among smallholder farmers. There is a need to build the capacity of extension to educate smallholders on a plant’s nutritional needs and proper fertilization. It also details how farmers’ needs assessments and human-centered design approaches need to be integrated while developing and delivering nutrient application recommendations and extension materials.

Nutrient subsidies must be reviewed to ensure they balance micro and macro-nutrients. Cross-country learning and evidence sharing on policies and subsidies to promote balanced nutrient application are discussed in the brief, as is the need to balance micro and macro-nutrient subsidies, in addition to the organization of subsidy programs in ways that assure farmers get access the right nutrients when and where they are needed the most. The brief also suggests additional research and evidence are needed to identify ways to assure that farmers’ behavior changes in response to subsidy programs.

Market, policy, and product innovations in the fertilizer industry must be encouraged. It describes the need for blended fertilizer products and programs to support them. A blend is made by mixing two or more fertilizer materials. For example, particles of nitrogen, phosphate and small amounts of secondary nutrients and micronutrients mixed together. Experience with blended products are uneven in the region, and markets for blends are nascent in Bangladesh and Nepal in particular. Cross-country technical support on how to develop blending factories and markets could be leveraged to accelerate blended fertilizer markets and to identify ways to ensure equitable access to these potentially beneficial products for smallholder farmers.

New tools guide interventions against acid soils in Africa using lime

Written by Jérôme Bossuet on October 31, 2019. Posted in Blogs.

One major reason why maize productivity in sub-Saharan Africa is very low is poor soil health. Soil acidity is often mentioned because of its impact on crop yields and the extent of acid soils in the region. A recent soil mapping exercise, conducted by the Ethiopian Soil Information System (EthioSIS) under the administration of the Ethiopian Agricultural Transformation Agency (ATA), estimated that 43% of arable lands were affected by acid soils and that 3.6 million people, about 10% of the total rural population, live in areas with acidic soils.

Very acid soils — those with a pH below 5.5, roughly one hundred times more acidic than neutral soils — are associated with certain toxicities, like aluminum and iron excess, and some nutrient deficiencies. Soil acidity pushes soil nutrients out of reach of the plant, leading to stunting of root system and plant. As a result, the plant becomes also less tolerant to drought.

Soil acidification depends on soil nature, agroecology and farming systems. It happens through natural leaching of CO2 after rainfall and excess application of nitrogenous fertilizer or organic matter, for instance.

As a result, soil acidity significantly affects maize yields. In Ethiopia, studies have revealed substantial impacts on crop productivity related to acid soils and the importance of acid soil management for Ethiopia’s food security. The Ethiopian Institute of Agricultural Research (EIAR) estimated that soil acidity on wheat production alone costed the country over 9 billion Ethiopian Birr, about $300 million per year.

Acidic soils in the limelight

Preliminary analysis led by the International Food Policy Research Institute (IFPRI) suggests that yields of major cereal crops, such as wheat and barley, could increase by 20 to 40% with the application of lime in acidic areas of the country.

While these preliminary results are significant, we need to know more about local farmers’ experience with acidic soil and their mitigation strategies. Such impact assessments are however typically determined at either the national or experimental plot level and do not map where mitigating against acid soils would be the most profitable.

To improve acid soils, farmers may apply lime on their fields to raise the pH, a practice known as liming. How much lime to apply will depend on the crop, soil type but also on the quality of lime available. Liming has multiple beneficial effects like improving nitrogen fixation of legume nodules, boosting yields of legume crops.

But liming has a cost. It can quickly become a very bulky affair as we need to apply 3 to 4 tons per hectare for sandy soils and up to 8 tons per hectare for clay and humifere soils.

Furthermore, existing lime markets are quite limited or even non-existent in many areas, even those where acidic soils are prevalent. Developing supply chains from scratch is difficult and costly. Understanding the costs and potential returns to such investments is important. There are many questions to ask at different levels, from the farm and farming system to the lime supply chain. What are the available lime sources — calcitic, dolomite or blend — and lime quality? Where are the lime processing units and how could you assess the transport cost to the farms? What could be the crop yield response depending on the lime application?

User-friendly and scalable dashboard

IFPRI, in collaboration with EIAR, the International Maize and Wheat Improvement Center (CIMMYT) and the German aid agency GIZ, developed a pilot in Ethiopia’s Amhara region to help better target lime interventions for a greater impact. Amhara region was chosen because of the importance of acid soils, and access to extensive soil data.

Combination of several spatial datasets on soil quality, agroecological, weather, long-term agronomic trials and crop modelling tools enabled to generate at scale, georeferenced estimates of crop yield responses for different lime applications. Calibration of this spatial model for wheat estimated a yield increase of approximately 30% increasing the pH from 5.5 to 6.5, which is relatively consistent with general research data and expert opinion.

Mapped estimates of the grain prices and the delivered costs of lime, based on the location of the lime crushers in the region and transport costs, enables then to map out the spatial profitability of lime operations.

Initial calculations revealed a great variability of lime costs at the farmgate, with transportation representing at least half of total lime costs. It showed also that farmers often do not use the most cost-effective combination of inputs to tackle soil acidity.

Another possible application is to determine maize growing areas where lime benefits outweigh the costs, which would be ideal sites for demonstrating to farmers the positive impact lime applications could have to their livelihoods.

This Amhara lime dashboard prototype demonstrated its scalability. A national dashboard is currently being developed, which includes lime sources GPS location, grain prices and district-level soil quality mapping. This approach is tested also in Tanzania.

CIMMYT and its partners plan to package such tool in a user-friendly open-access web version that can be rapidly updated and customized depending on the area of intervention, for instance integrating a new lime source, and applied for different crops, and across the Eastern African region. Such dashboards will help development organizations and government make better informed decisions regarding lime investments.

Genome editing, gene drives, and synthetic biology: Will they contribute to disease-resistant crops, and who will benefit?

Written by Mike Listman on September 3, 2019. Posted in News.

Ensuring the access of small-scale farmers to products and potential benefits from genetic engineering (GE) technologies for agriculture will require concerted investment and research by public institutions worldwide and particularly in low- and middle-income countries.

This was a key conclusion of a new review paper describing cutting-edge GE applications that offer exciting options to enhance the disease and pest resistance of important food crops and the ecological sustainability of cropping systems.

The technologies include gene editing (site-specific changes to DNA in a genome), gene drives (greatly enhancing or reducing frequency of genes that affect insect or pathogen reproduction), and synthetic biology (re-design or construction of biological devices, for example chromosomes or organelles).

Authored by international experts in policy, socioeconomics, and biological science, the new paper outlines potential uses of the technologies, particularly to address problems that affect resource-poor farmers or consumers, such as the viruses that attack cassava, the Striga weed that is a parasite of maize, or the fungal pathogen of groundnut that produces deadly toxins.

A weak capacity for research and development in many countries, combined with a small and declining public investment, raises questions about those nations’ ability to develop and deliver high-quality GE technologies or realize their benefits.

“The concern is that farmers not served by leading companies, who are developing the technologies, will be unable to obtain new, resistant crop varieties or other products of these technologies,” said Kevin Pixley, director of the genetic resources program of the International Maize and Wheat Improvement Center (CIMMYT) and first author of the new paper.

The technologies have already proven effective for controlling bacterial, fungal, and viral plant pathogens, as well as insects that transmit them. For example, GE approaches to control cassava brown streak disease and cassava bacterial blight—for which there are few or no known sources of resistance in cassava itself—appear on track to produce resistant versions of cassava.

Future gene drive technologies that can be kept within specific areas and reversed if needed may offer ways to control insects that carry plant diseases or weeds that damage crops, and synthetic biology could someday create plants that are immune to invading viruses.

“The private sector is likely to invest mainly in major crops and major traits that will bring them profits, so work on minor, perennial, clonal, or staple food crops of lower-income countries may suffer,” said José Falck-Zepeda, senior research fellow and leader of the policy team in the program for biosafety systems of the International Food Policy Research Institute (IFPRI) and a co-author of the review paper.

Many countries are still deciding whether and how they will regulate new GE products. The new paper explains how key factors including the cost and complexity of complying with biosafety regulations will shape the potential distribution of the technologies and products, determining which institutions undertake the related research and, as a result, which traits and crops are studied.

Civil society concerns regarding GE technologies and how or by whom they are deployed add important considerations to the complex questions surrounding the use of GE products.

“Realizing the potential of GE crops will require investments and policies for research, intellectual property regimes, and regulatory frameworks,” say the authors, “and societies must also address legitimate concerns about their responsible stewardship, agroecological sustainability, and equitable access to associated benefits.”

Precision spreader for fertilizer set to change the agriculture scene in Nepal

Smallholder farmers in Nepal tend to apply fertilizer by hand, spreading it as they walk through the field. Under this practice, fertilizer is dispersed randomly and is therefore unevenly distributed among all the seedlings. A recently introduced method, however, helps farmers spread fertilizer in a more uniform, faster and easier way.

The precision spreader is a hand-operated device that ensures an even distribution of fertilizer and is easy to operate. This technology is endorsed by the Cereal Systems Initiative for South Asia (CSISA), a project led by the International Maize and Wheat Improvement Center (CIMMYT) which helps Nepalese farmers adapt measures that are efficient, effective and resilient to the impacts of climate change.

In addition to more consistent distribution, the precision spreader regulates the exact amount of fertilizer required and helps the farmer cover a considerable area with limited movement. This technology has been proven to require less time and effort than the traditional method of broadcasting by hand.

Considering the potential benefits, the CSISA team introduced farmers in Nepal to the precision spreader through training sessions followed by demonstrations of its use. They took place in wheat fields in Bansgadhi, Barbardiya and Duduwa, in Lumbini province, in collaboration with multipurpose cooperative Janaekata and the local governments. Through these sessions, conducted in 45 different sites, more than 650 farmers had a chance to familiarize themselves with the precision spreader, and most of them took a keen interest in incorporating the device into their cropping management practices.

Perhaps the most prominent reason why the precision spreader sparked such interest is that women can easily use it. Most men in rural areas have migrated to the city or abroad in hopes of higher income, so work in the fields has been inadvertently transferred to women. Since Nepal is a predominantly conservative patriarchal society, women have not yet become comfortable and familiarized with all farming practices, especially operating heavy agricultural machinery. However, as expressed by women themselves, the precision spreader is highly convenient to use. Its use could help ease women into the agriculture scene of Nepal and consequently reduce farming drudgery.

Healthier crops, healthier people

Nestled between China and India, Nepal predominantly relies on agriculture for employment. With the majority of its population engaged in the agricultural sector, the country still struggles to produce an adequate food supply for its people, resulting in depressed rural economies, increased malnutrition and widespread hunger.

Sustainable intensification, therefore, is necessary to increase the overall yield and to accelerate agricultural development.

Better distribution of fertilizer in the fields results in a higher chance of healthier crops, which are the source of better nutrition.

A wider use of a seemingly small technology like the precision spreader would not only reduce hardships in farming, but it would also help farmers become more resilient towards the natural and economic adversities they face.

The Cereal Systems Initiative for South Asia (CSISA) is a regional project in Bangladesh, India and Nepal that was established in 2009 with the goal of benefiting more than 8 million farmers by the end of 2020. Funded by the United States Agency for International Development (USAID) and the Bill & Melinda Gates Foundation, CSISA is led by the International Maize and Wheat Improvement Center (CIMMYT) and implemented jointly with the International Food Policy Research Institute (IFPRI) and the International Rice Research Institute (IRRI).

Cranking, a thing of the past

Written by Rodrigo Ordóñez on July 10, 2019. Posted in Features. 1 Comment on Cranking, a thing of the past

Halima Begum wanted to increase her income by providing mechanization services to other farmers in Bangladesh’s Chuadanga district, but she was limited by the level of physical effort required. Starting the engine of her tractor was difficult and embarrassing — cranking it required a lot of strength and she had to rely on others to do it for her. She was also afraid she would get injured, like other local service providers.

Women in rural areas of Bangladesh are often hesitant to work in the fields. Social norms, limited mobility, physical exertion, lack of time and other constraints can cause aspiring female entrepreneurs to step back, despite the prospect of higher income. The few women like Halima who do step out of their comfort zone and follow their dreams often have to overcome the physical effort required to operate these machines.

Starting the tractor is a daunting task on its own and the possibility of having to do it multiple times a day adds to the reluctance of ownership.

To make manual cranking a thing of the past for Bangladeshi women entrepreneurs, and to encourage others, the International Maize and Wheat Improvement Center (CIMMYT), through the Cereal Systems Initiative for South Asia-Mechanization and Irrigation (CSISA-MI), is supporting small businesses who manufacture and sell affordable mechanical self-starter attachments for two-wheel tractors.

The self-starter is a simple spring-loaded device mounted over the old crank handle socket, which allows users to start the engine with the flick of a lever.

For women like Begum, manually starting a tractor was a difficult task that is now gone forever.

“I used to struggle quite a lot before, but now I can easily start the machine, thanks to this highly convenient self-starter,” Begum said.

The self-starter reduces the risk of accidents and coaxes hesitant youth and women to become entrepreneurs in the agricultural mechanization service industry.

CIMMYT is supporting businesses like Janata Engineering, which imports self-starter devices and markets them among local service providers in the district of Sorojgonj, Chuadanga district. The project team worked with the owner, Md. Ole Ullah, to organize field demonstrations for local service providers, showing how to use and maintain the self-starter device.

The Cereal Systems Initiative for South Asia-Mechanization and Irrigation (CSISA-MI) is led by the International Maize and Wheat Improvement Center (CIMMYT) and funded by the United States Agency for International Development (USAID). The project focuses on upstream market interventions in Bangladesh, ensuring technologies are reliably available in local markets and supported by an extensive value chain.

Research, innovation, partnerships, impact

On May 15, 2019, as part of the CGIAR System Council meeting held at the ILRI campus in Addis Ababa, Ethiopia, around 200 Ethiopian and international research and development stakeholders convened for the CGIAR Agriculture Research for Development Knowledge Share Fair. This exhibition offered a rare opportunity to bring the country’s major development investors together to learn and exchange about how CGIAR investments in Ethiopia help farmers and food systems be more productive, sustainable, climate resilient, nutritious, and inclusive.

Under the title One CGIAR — greater than the sum of its parts — the event offered the opportunity to highlight close partnerships between CGIAR centers, the Ethiopian government and key partners including private companies, civil society organizations and funding partners. The fair was organized around the five global challenges from CGIAR’s business plan: planetary boundaries, sustaining food availability, promoting equality of opportunity, securing public health, and creating jobs and growth. CGIAR and its partners exhibited collaborative work documenting the successes and lessons in working through an integrated approach.

There were 36 displays in total, 5 of which were presented by CIMMYT team members. Below are the five posters presented.

How can the data revolution help deliver better agronomy to African smallholder farmers?

This sustainability display showed scalable approaches and tools to generate site-specific agronomic advice, developed through the Taking Maize Agronomy to Scale in Africa (TAMASA) project in Nigeria, Tanzania and Ethiopia.

This poster describes how CGIAR works with Ethiopia’s research & development sector to support national food security priorities.

Addressing gender norms in Ethiopia’s wheat sector

Research shows that restrictive gender norms prevent women’s ability to innovate and become productive. This significantly impacts Ethiopia’s economy (over 1% GDP) and family welfare and food security.

Quality Protein Maize (QPM) for better nutrition in Ethiopia

With the financial support of the government of Canada, CIMMYT together with national partners tested and validated Quality Protein Maize as an alternative to protein intake among poor consumers.

Appropriate small-scale mechanization

The introduction of small-scale mechanization into the Ethiopian agriculture sector has the potential to create thousands of jobs in machinery service provision along the farming value chain.

About the CGIAR System Council

The CGIAR System Council is the strategic decision-making body of the CGIAR System that keeps under review the strategy, mission, impact and continued relevancy of the System as a whole. The Council meets face-to-face not less than twice per year and conducts business electronically between sessions. Additional meetings can be held if necessary.

A burning issue

Written by Rodrigo Ordóñez on June 4, 2019. Posted in Photos.

Pollution has become a part of our daily life: particulate matter in the air we breathe, organic pollutants and heavy metals in our food supply and drinking water. All of these pollutants affect the quality of human life and create enormous human costs.

The burning of crop residue, or stubble, across millions of hectares of cropland between planting seasons is a visible contributor to air pollution in both rural and urban areas. (Photo: Dakshinamurthy Vedachalam/CIMMYT)

India is home to 15 of the world’s cities with the highest air pollution, making it a matter of national concern. The country is the world’s third largest greenhouse gas emitter, where agriculture is responsible for 18% of total national emissions.

For decades, CIMMYT has engaged in the development and promotion of technologies to reduce our environmental footprint and conserve natural resources to help improve farmer’s productivity.

Efficient use of nitrogen fertilizers, better management of water, zero-tillage farming, and better residue management strategies offer viable solutions to beat air pollution originating from the agriculture sector. Mitigation measures have been developed, field tested, and widely adopted by farmers across Bangladesh, India, Nepal and Pakistan.

“Multi-lateral impacts of air pollution link directly it to various sustainability issues,” explained Balwinder Singh, Cropping Systems Simulation Modeler at CIMMYT. “The major sustainability issues regarding air quality revolve around the common question: How good is good enough to be sustainable? We need to decide how to balance the sustainable agriculture productivity and hazardous pollution levels. We need to have policies on the regulation of crop burning and in addition to policies surrounding methods to help reach appropriate air quality levels.”

Bangladesh increases efforts to fight fall armyworm

Written by Rodrigo Ordóñez on May 30, 2019. Posted in News.

The International Maize and Wheat Improvement Center (CIMMYT) and the Bangladesh Wheat and Maize Research Institute (BWMRI), organized a training on fall armyworm on April 25, 2019 at the Bangladesh Agricultural Research Council (BARC). Experts discussed the present outbreak status, progress on strategic research, and effective ways to control this destructive pest.

The event featured Dan McGrath, Entomologist and Professor Emeritus at Oregon State University, and Joseph Huesing, Senior Biotechnology Advisor and Program Area Lead for Advanced Approaches to Combating Pests and Diseases at the United States Agency for International Development (USAID). Also attending were senior officials from Bangladesh Agricultural Research Institute (BARI), Bangladesh Rice Research Institute (BRRI), Bangladesh Agricultural University (BAU), Department of Agricultural Extension, BARC, BWMRI and CIMMYT.

“Fall armyworm cannot be eradicated. It is endemic and farmers have to learn to manage it,” said Huesing in his overview of the fall armyworm infestation in Africa. He also mentioned that fall armyworm is generally followed by southern armyworm, so Bangladesh will need a strategy for managing multiple pests.

“Fall armyworm cannot be eradicated. It is endemic and farmers have to learn to manage it.”
— Joseph Huesing, USAID

Huesing explained that an effective approach for controlling fall armyworm and other pests is “knowledge, tools and policy.”

According to Huesing, Bangladeshi farmers have adequate knowledge about the pest and how to control it, especially compared to African farmers. The next step is securing the necessary tools to control fall armyworm, like spraying their fields with necessary insecticides by authorized personnel. Huesing emphasized the importance of appropriate policy implementation, particularly to ensure the registration of the right kind of insecticides assigned to effectively control fall armyworm.

Fall armyworm is a fast-reproducing species that can attack crops and cause devastation almost overnight. Even though the level of infestation in Bangladesh is still relatively light, more than 80 varieties of crops have already been attacked in 22 districts within just a few months.

Huesing indicated that safer options included handpicking of the pest, treating seeds, pheromone traps, flood irrigation and crop rotation. Currently, to help farmers learn more about the pest, the Department of Agricultural Extension is distributing factsheets and conducting awareness-raising workshops in different villages.

McGrath focused on the long-term management of fall armyworm and how Bangladesh can learn from the experience of Africa in order to avoid the same errors. McGrath suggested that weather forecasts were an important tool for helping determine when and where outbreaks might occur. Training relevant personnel is also a crucial aspect of reining in this plague. “Training the trainers has to be hands on. We need to put more emphasis on the field than on the classroom,” McGrath said.

This workshop was part of the Cereal Systems Initiative for South Asia (CSISA).

The fall armyworm, explained

Written by Rodrigo Ordóñez on May 30, 2019. Posted in Infographics.

As part of the Cereal Systems Initiative for South Asia (CSISA), the International Maize and Wheat Improvement Center (CIMMYT) has created a series of infographics explaining key information about fall armyworm.

These infographics will be translated and used to reach out to farmers in Bangladesh, through agrodealers and public sector partners. The principles and concepts presented in them — which champion the use of integrated pest management strategies — are relevant to countries across the region.

If you would like to use these infographics in other countries or translate them to other languages, please contact Tim Krupnik.

Fall armyworm is an invasive insect pest that can eat 80 different types of plants, but prefers maize. It spread throughout Africa in just two years, and was found in India in late 2018. Since then it has spread across South and South East Asia, where it presents a serious threat to food and income security for millions of smallholder farmers.

The infographics are designed to be printed as foldable cards that farmers can carry in their pocket for easy reference. The graphics provide an overview of fall armyworm biology as well as the insect’s ecology and lifecycle. They also describe how to identify and scout maize fields for fall armyworm and provide easy-to-follow recommendations for what to do if thresholds for damage are found. One of the infographics provides farmers with ideas on how to manage fall armyworm in their field and village, including recommendations for agronomic, agroecological, mechanical and biological pest management. In addition, chemical pest management is presented in a way that informs farmers about appropriate safety precautions if insecticide use is justified.

Cereal Systems Initiative for South Asia (CSISA)

Written by Rodrigo Ordóñez on March 26, 2019. Posted in Uncategorized.

Intensive cereal cropping systems that include rice, wheat and/or maize are widespread throughout South Asia. These systems constitute the main economic activity in many rural areas and provide staple food for millions of people. The decrease in the rate of growth of cereal production, for both grain and residue, in South Asia is therefore of great concern. Simultaneously, issues of resource degradation, declining labor availability and climate variability pose steep challenges for achieving the goals of improving food security and rural livelihoods.

The Cereal Systems Initiative for South Asia (CSISA) was established in 2009 to promote durable change at scale in South Asia’s cereal-based cropping systems.

The project’s aim is to enhance the productivity of cereal-based cropping systems, increase farm incomes and reduce the environmental footprint of production through sustainable intensification technologies and management practices.

Operating in rural “innovation hubs” in Bangladesh, India and Nepal, CSISA complements regional and national efforts and involves public, civil society and private sector partners in the development and dissemination of improved cropping systems, resource-conserving management technologies, policies and markets. CSISA supports women farmers by ensuring their access and exposure to modern and improved technological innovations, knowledge and entrepreneurial skills that can help them become informed and recognized decision makers in agriculture.

The project is led by CIMMYT with partners the International Rice Research Institute and the International Food Policy Research Institute and funded by the U.S. Agency for International Development and the Bill & Melinda Gates Foundation.

OBJECTIVES

Promote resource-conserving practices, technologies and services that increase yield with less water, labor and input costs
Impart new knowledge on cropping management practices, from applied research
Improve access to market information and enterprise development.
Strengthen policy analysis to remove constraints to the adoption of new technologies
Build strategic partnerships and capacity to help sustain and enhance the scale of benefits of improved cereal growth

Core research to impact themes within CSISA include:

Coping with climate extremes in rice-wheat cropping systems
Accelerating the emergence of mechanized solutions for sustainable intensification
Strengthening the foundations of agro-advisory and precision management through knowledge organization and data integration at scale
Increasing the capacity of partners to conduct participatory science and field reconnaissance to target and prioritize development interventions

Support groups open women’s access to farm technologies in northeast India

Self-help groups in Bihar, India, are putting thousands of rural women in touch with agricultural innovations, including mechanization and sustainable intensification, that save time, money, and critical resources such as soil and water, benefiting households and the environment.

The Bihar Rural Livelihoods Promotion Society, locally known as Jeevika, has partnered with the Cereal Systems Initiative for South Asia (CSISA), led by the International Maize and Wheat Improvement Center (CIMMYT), to train women’s self-help groups and other stakeholders in practices such as zero tillage, early sowing of wheat, direct-seeded rice and community nurseries.

Through their efforts to date, more than 35,000 households are planting wheat earlier than was customary, with the advantage that the crop fully fills its grain before the hot weather of late spring. In addition, some 18,000 households are using zero tillage, in which they sow wheat directly into unplowed fields and residues, a practice that improves soil quality and saves water, among other benefits. As many as 5,000 households have tested non-flooded, direct-seeded rice cultivation during 2018-19, which also saves water and can reduce greenhouse gas emissions.

An autonomous body under the Bihar Department of Rural Development, Jeevika is also helping women to obtain specialized equipment for zero tillage and for the mechanized transplanting of rice seedlings into paddies, which reduces women’s hard labor of hand transplanting.

“Mechanization is helping us manage our costs and judiciously use our time in farming,” says Rekha Devi, a woman farmer member of Jeevika Gulab self-help group of Beniwal Village, Jamui District. “We have learned many new techniques through our self-help group.”

With more than 100 million inhabitants and over 1,000 persons per square kilometer, Bihar is India’s most densely-populated state. Nearly 90 percent of its people live in rural areas and agriculture is the main occupation. Women in Bihar play key roles in agriculture, weeding, harvesting, threshing, and milling crops, in addition to their household chores and bearing and caring for children, but they often lack access to training, vital information, or strategic technology.

Like all farmers in South Asia, they also face risks from rising temperatures, variable rainfall, resource degradation, and financial constraints.

Jeevika has formed more than 700,000 self-help groups in Bihar, mobilizing nearly 8.4 million poor households, 25,000 village organizations, and 318 cluster-level federations in all 38 districts of Bihar.

The organization also fosters access for women to “custom-hiring” businesses, which own the specialized implement for practices such as zero tillage and will sow or perform other mechanized services for farmers at a cost. “Custom hiring centers help farmers save time in sowing, harvesting and threshing,” said Anil Kumar, Program Manager, Jeevika.

The staff training, knowledge and tools shared by CSISA have been immensely helpful in strengthening the capacity of women farmers, according to D. Balamurugan, CEO of Jeevika. “We aim to further strengthen our partnership with CSISA and accelerate our work with women farmers, improving their productivity while saving their time and costs,” Balamurugan said.

CSISA is implemented jointly by the International Maize and Wheat Improvement Center (CIMMYT), the International Food Policy Research Institute (IFPRI) and the International Rice Research Institute (IRRI). It is funded by the Bill & Melinda Gates Foundation and the United States Agency for International Development (USAID).

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.

NEW DELHI (CIMMYT) — Imbalanced application of different plant nutrients through fertilizers is a widespread problem in India. The major reasons are lack of adequate knowledge among farmers about the nutritional requirement of crops, poor access to proper guidelines on the right use of plant nutrients, inadequate policy support through government regulations, and distorted and poorly targeted subsidies.

This context makes it necessary to foster innovation in the fertilizer industry, and also to find innovative ways to target farmers, provide extension services and communicate messages.

A dialogue on “Innovations for promoting balanced application of macro and micro nutrient fertilizers in Indian agriculture” facilitated discussion on this issue. Representatives from key fertilizer industries, state governments, research institutions and the Indian Council of Agricultural Research gathered in New Delhi, India, on December 12, 2018. This dialogue was part of the Cereal Systems Initiative for South Asia (CSISA) and was organized by the International Food Policy Research Institute (IFPRI) and the International Plant Nutrition Institute (IPNI).

The Director General of the Fertilizer Association of India (FAI), Shri Satish Chander, pointed out that new-product approvals in India take approximately 800 days. However, he explained, this delay is not the biggest problem facing the sector: other barriers include existing price controls that are highly contingent on political myths.

IFPRI researcher Avinash Kishore presented evidence contradicting the myth that farmers are highly sensitive to any price change. He presented data demonstrating that farmers’ demand for Urea and DAP remained highly price inelastic during periods of steep price increases, in 2011 and 2012.

The Director of the South Asia Program at IPNI, T. Satyanarayana, highlighted the importance of micronutrients in promoting balanced fertilization of soils and innovative methods for determining soil health.

Andrew McDonald, from the International Maize and Wheat Improvement Center (CIMMYT), presented the new Soil Intelligence System for India, which employs innovative approaches to soil health assessments.

Farmers’ representative Ajay Vir Jakhar elaborated on the failure of underfunded extension systems to reach and disseminate relevant, factual and timely messages to vast numbers of farmers.

Other representatives from the fertilizer industry touched upon the need to identify farmer requirements for risk mitigation, labor shortages and site-specific nutrient management needs for custom fertilizer blends. Participants also discussed field evidence related to India’s soil health card scheme. Ultimately, discussions held at the roundtable helped identify relevant policy gaps, which will be summarized into a policy brief.

A wheat self-sufficiency roadmap for Ethiopia’s future

Written by Jérôme Bossuet on December 5, 2018. Posted in Features.

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

The low-tech domestic wheat farming and price support issue

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

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

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

Where to start to boost wheat productivity?

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

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

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

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

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

Invest in soil health, mechanization and gender

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

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

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

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

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

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

New Soil Intelligence System for India provides high-quality data using modern analytics

Written by on December 4, 2018. Posted in Features.

NEW DELHI (CIMMYT) — The new Soil Intelligence System (SIS) for India will help the states of Andhra Pradesh, Bihar and Odisha rationalize the costs of generating high-quality soil data and build accessible geospatial information systems based on advanced geostatistics. The SIS initiative will rely on prediction rather than direct measurements to develop comprehensive soil information at scale. The resulting data systems will embrace FAIR access principles — findable, accessible, interoperable, and reproducible — to support better decision-making in agriculture.

SIS is a $2.5 million investment funded by the Bill & Melinda Gates Foundation. This initiative is led by the International Maize and Wheat Improvement Center (CIMMYT), in collaboration with numerous partners including the International Food Policy Research Institute (IFPRI), World Soil Information (ISRIC), the Andhra Pradesh Space Applications Center (APSAC), and the state governments and state agriculture universities of Andhra Pradesh and Bihar. The initiative runs from September 2018 through February 2021.

“SIS will make important contributions towards leveraging soil information for decision-making in Indian agriculture by devising new soil health management recommendations,” explained Andrew McDonald, CIMMYT’s Regional Team Leader for Sustainable Intensification and Project Leader for the Cereal Systems Initiative for South Asia (CSISA). Researchers and scientists will combine mapping outputs with crop response and landscape reconnaissance data through machine-learning analytics to derive precise agronomy decisions at scale.

Farmers will be the primary beneficiaries of this initiative, as they will get more reliable soil health management recommendations to increase yields and profits. SIS will also be useful to state partners, extension and agricultural development institutions, the private sector and other stakeholders who rely on high-quality soil information. Through SIS, scientists and researchers will have an opportunity to receive training in modern soil analytics.

The SIS initiative aims to facilitate multi-institutional alliances for soil health management and the application of big data analytics to real-world problems. These alliances will be instrumental for initiating broader discussions at the state and national levels about the importance of robust data systems, data integration and the types of progressive access policies related to ‘agronomy at scale’ that can bring India closer to the Sustainable Development Goals.

Better soil analysis

Spectroscopy enables precise soil analysis and can help scientists identify appropriate preventive and rehabilitative soil management interventions. The technology is also significantly faster and more cost-effective than wide-scale wet chemistry-based soil analysis.

As part of the CSISA project, led by CIMMYT and funded by the Bill & Melinda Gates Foundation, two new soil spectroscopy labs were recently set up in Andhra Pradesh and Bihar, in collaboration with the state departments of agriculture. One lab is now operating at the Regional Agricultural Research Station (RARS) in Tirupati, Andhra Pradesh; and the other one at Bihar Agricultural University (BAU Sabour), in Bhagalpur, Bihar.

“The support from CIMMYT through the Gates Foundation will contribute directly to bringing down the cost of providing quality soil health data and agronomic advisory services to farmers in the long run,” said K.V. Naga Madhuri, Principal Scientist for Soil Science at Acharya N. G. Ranga Agricultural University. “We will also be able to generate precise digital soil maps for land use planning. The greatest advantage is to enable future applications like drones to use multi-spectral imagery and analyze rapidly large areas and discern changes in soil characteristics in a fast and reliable manner.”

Under the SIS initiative, soil spectroscopy results will be validated with existing gold standard wet chemistry methods. They will also be integrated with production practice data collected from the ground level, through new statistical tools.

Precise predictive models

Drawing information from a limited number of soil observations from a sample dataset, digital soil mapping (DSM) uses (geo)statistical models to predict the soil type or property for locations where no samples have been taken.

“These ‘unsampled locations’ are typically arranged on a regular grid,” explained Balwinder Singh, CIMMYT scientist and Simulation Modeler, “so DSM produces gridded — raster — soil maps at a specific spatial resolution — grid cell or pixel size — with a spatial prediction made for each individual grid cell.”

“Adopting DSM methods, combined with intelligent sampling design, could reduce the strain on the soil testing system in terms of logistics, quality control and costs,” noted Amit Srivastava, a geospatial scientist at CIMMYT. “Improving digital soil mapping practices can also help create the infrastructure for a soil intelligence system that can drive decision-making at scale.”

In partnership with state government agencies and the Bill & Melinda Gates Foundation, CIMMYT will continue to support the expansion of digital soil mapping and soil analysis capacity in India. The CSISA project and the SIS initiative are helping to deliver soil fertility recommendations to farmers, an important step towards the sustainable intensification of agriculture in South Asia.
