Crowdsourced data feeds fall armyworm surveillance in Bangladesh

Written by Matthew O'Leary on . Posted in Features.

Following the spread of fall armyworm, crowdsourced data is powering a web-based application to help farmers in Bangladesh stay ahead of the crop pest.

The Fall Armyworm Monitor collects population, incidence and severity data, and guides pest management decisions. The web tool relies on information gathered by farmers using smartphones in their fields.

It was developed by the International Maize and Wheat Improvement Center (CIMMYT) in cooperation with Bangladesh’s Department of Agricultural Extension, through the Fighting Back Against Fall Armyworm project, supported by USAID and Michigan State University.

When a foreign caterpillar first munched through Muhammad Hasan Ali’s maize field during the winter 2018-2019 season, he was stumped as to what it was or how to manage it. All he knew was his harvest and the investment he made in growing his crop was at risk.

“I’d never seen this type of insect in previous seasons, but I soon learned from government extension workers it was the fall armyworm,” explained Hasan Ali, a farmer from rural Chuadanga, in western Bangladesh. When poorly managed, fall armyworm can significantly reduce maize productivity.

Hasan Ali asked to join a training program, where he learned how to identify, monitor and control the spread of the invasive and voracious crop pest. The training, mainly tailored to extension staff, was facilitated by CIMMYT and Bangladesh’s Department of Agricultural Extension.

Equipped to fight the pest

Extension staff and farmers gained valuable insights into different methods of control, including management of small and large patches of insect attack.

“I learned to identify fall armyworms in my field — and how to use hand picking methods and appropriate application of insecticide for control,” said Hasan Ali.

Farmers also learned how to set up pheromone traps to monitor pest populations and to use smartphones to make data-driven integrated pest management decisions using a cloud-based monitoring platform.

Crowdsourced information on the movement of fall armyworm is essential for effectively monitoring its spread and is a pivotal step in its management, said CIMMYT Senior Scientist and Systems Agronomist Timothy Krupnik.

“Farmers in top maize growing regions are working with extension officers to monitor traps and report findings weekly by entering data into smartphones,” Krupnik said.

Pheromones are natural compounds emitted by female moths to attract males for mating. Synthetic compounds that mimic natural fall armyworm pheromones are placed in traps to lure and capture male moths, after which extension agents count moths, enter, and upload data in their districts. At the time of writing, 649 staff from the Department of Agricultural Extension are reporting weekly moth count and pest damage data.

“Pest management practices are best when they are data-driven,” Krupnik explained. “Having information on the geographical location, plant growth stage and severity of infestation provides an informed base from which appropriate decisions can be made, with the ultimate goal of reducing pesticide misuse.”

“We are also excited as the data are open-access, and we are working to share them with FAO and other partners crucial in fall armyworm response,” he added.

Data for better decisions

“The website hosts real-time data and depicts them graphically and in maps depending on user’s preferences. This information — which was core to the training extension agents participated in — is key for integrated pest management strategies,” explained Mutasim Billah, CIMMYT Data Specialist and the lead developer of the application.

“The department of extension services have employed 253 officers to visit fields with handheld smart devices in 25 districts to upload data,” said Billah. “The online tool stores data entries in its server and calculates the aggregated value for division, district and sub-district level on a weekly basis, and shows the estimated values through charts and in tabular format.”

The Fall Armyworm Monitor has become an essential tool for government officials to aid farmers in managing the pest which so far has been successful, said Bijoy Krishna Halder, additional Deputy Director of Plant Protection with the Bangladesh government.

“CIMMYT’s web portal is a very efficient way to collect data from the field. Anyone can access the page to see the overall condition of infestation across the country,”said Krishna Halder. “I check the portal every week about the fall armyworm condition and now it shows that the infestation is low with the overall field conditions good.”

The pest native to the Americas has become a global menace as it has spread attacking crops through Africa, and Asia, threatening the food and economic security of smallholder farmers.

Although the conventional wisdom in South Asian rural villages is that men are principally responsible for pulling their families out of poverty, our recent study showed the truth to be more subtle, and more female.

In our new paper we dig into focus groups and individual life stories in a sample of 32 farming villages from five countries of South Asia. Although we asked about both men’s and women’s roles, focus groups of both sexes emphasized men in their responses — whether explaining how families escaped poverty or why they remained poor.

“Women usually cannot bring a big change, but they can assist their men in climbing up,” explains a member of the poor men’s focus group from Ismashal village (a pseudonym) of Pakistan’s Khyber Pakhtunkhwa province.

The focus group testimonies presented rich examples of the strong influence of gender norms: the social rules that dictate differential roles and conducts for men and women in their society. These norms significantly influenced how local people conceived of movements in and out of poverty in their village and in their own lives.

According to the women’s focus group from Rangpur district in Bangladesh, women “cannot work outside the home for fear of losing their reputation and respect.”

However, in these same communities, men’s and women’s productive roles proved far more variable in the mobility processes of their families than conveyed by the focus groups. We encountered many households with men making irregular or very limited contributions to family maintenance. This happens for a number of reasons, including men’s labor migration, disability, family conflict and separations, aging and death.

What’s more, when sharing their life stories in individual interviews, nearly every woman testified to her own persistent efforts to make a living, cover household expenses, deal with debts, and, when conditions allowed, provide a better life for their families. In fact, our life story sample captured 12 women who testified to making substantial contributions to moving their families out of poverty.

Movers and shakers

We were especially struck by how many of these women “movers” were employing innovative agricultural technologies and practices to expand their production and earnings.

“In 2015, using zero tillage machines I started maize farming, for which I had a great yield and large profit,” reports a 30-year-old woman and mother of two from Matipur, Bangladesh who brought her family out of poverty.

Another 30-year-old mover, a farmer and mother of two from the village of Thool in Nepal, attests to diversification and adoption of improved cultivation practices: “I got training on vegetable farming. In the beginning the agriculture office provided some vegetable seeds as well. And I began to grow vegetables along with cereal crops like wheat, paddy, maize, oats. [
] I learnt how to make soil rows.”

Among the women who got ahead, a large majority credited an important man in their life with flouting local customs and directly supporting them to innovate in their agricultural livelihoods and bring their families out of poverty.

Across the “mover” stories, women gained access to family resources which enabled them to step up their livelihood activities. For example, three quarters of the women “movers” spoke of husbands or brothers supporting them to pursue important goals in their lives.

Women’s most important relationship helping them to pursue goals in life: women “movers” (on left) versus “chronic poor” (right).

Sufia, from a village in the Rajshahi district of Bangladesh, describes how she overcame great resistance from her husband to access a farm plot provided by her brother. The plot enabled Sufia to cultivate betel leaves and paddy rice, and with those profits and additional earnings from livestock activities, she purchased more land and diversified into eggplant, chilies and bitter gourd. Sufia’s husband had struggled to maintain the family and shortly after Sufia began to prosper, he suffered a stroke and required years of medical treatments before passing away.

When Sufia reflects on her life, she considers the most important relationship in her life to be with her brother. “Because of him I can now stand on my two feet.”

We also studied women and their families who did not move out of poverty. These “chronic poor” women rarely mentioned accessing innovations or garnering significant benefits from their livelihoods. In these life stories, we find far fewer testimonies about men who financially supported a wife or sister to help her pursue an important goal.

The restrictive normative climate in much of South Asia means that women’s capacity to enable change in their livelihoods is rarely recognized or encouraged by the wider community as a way for a poor family to prosper. Still, the life stories of these “movers” open a window onto the possibilities unlocked when women have opportunities to take on more equitable household roles and are able to access agricultural innovations.

The women movers, and the men who support them, provide insights into pathways of more equitable agricultural change. What we can learn from these experiences holds great potential for programs aiming to relax gender norms, catalyze agricultural innovation, and unlock faster transitions to gender equality and poverty reduction in the region. Nevertheless, challenging social norms can be risky and can result in backlash from family or other community members. To address this, collaborative research models offer promise. These approaches engage researchers and local women and men in action learning to build understanding of and support for inclusive agricultural change. Our research suggests that such interventions, which combine social, institutional and technical dimensions of agricultural innovation, can help diverse types of families to leave poverty behind.

New publication: Scaling agricultural mechanization services in smallholder farming systems

Written by Emma Orchardson on . Posted in Publications.

A new study by researchers at the International Maize and Wheat Improvement Center (CIMMYT) assesses how three large projects have scaled service provision models for agricultural mechanization in Bangladesh, Mexico and Zimbabwe. In what is possibly the first cross-continental assessment of these issues to date, the study gauges the extent to which each initiative fits with the needs of its environment to enable sustained machinery use by farmers at a large scale, while acknowledging the influence of project design on outcomes.

Each of the projects has made considerable progress towards increasing the adoption of agricultural machinery in their target area. In Bangladesh and Mexico, mechanization service providers and machinery dealers have been able to strengthen their business cases because the projects use geospatial and market data to provide targeted information on client segmentation and appropriate cropping systems. In Zimbabwe, CIMMYT and partners have worked to strengthen the market for two-wheeled tractors by creating demand among smallholders, developing the capacity of existing vocational training centers, and spurring private sector demand.

However, despite these initial successes, it can often be difficult to gauge the sustained change and transformative nature of such interventions.

Applying a scaling perspective

To address this challenge, research teams held a series of workshops with project partners in each country, including regional government representatives, national and local private sector stakeholders, and direct project collaborators such as extension agents and site managers. Participants were asked to answer a series of targeted questions and prompts using the Scaling Scan, a user-friendly tool which facilitates timely, structured feedback from stakeholders on issues that matter in scaling. Responses given during this exercise allowed project designers to analyze, reflect on, and sharpen their scaling ambition and approach, focusing on ten scaling ‘ingredients’ that need to be considered to reach a desired outcome, such as knowledge and skills or public sector governance.

“Although at first sight the case studies seem to successfully reach high numbers of end users, the assessment exposes issues around the sustainable and transformative nature of the project interventions,” says Lennart Woltering, a scaling advisor at CIMMYT.

The added value of this approach, explains Jelle Van Loon, lead author and CIMMYT mechanization specialist, is that lessons learned from project-focused interventions can be amplified to generate broader, actionable knowledge and implement thematic strategies worldwide. “This is especially important for CIMMYT as we do exactly that, but often face different constraints depending on the local context.”

The use of a scaling perspective on each of these projects exposed important lessons on minimizing project dependencies. For example, though each project has invested considerably in both capacity and business development training, in all three case studies the large-scale adoption of recommended service provision models has been limited by a lack of finance and insufficient collaboration among the value chain actors to strengthen and support mechanization service provider entrepreneurs.

“While provision of market and spatial information helps local businesses target their interventions, local stakeholders are still dependent on the projects in terms of transitioning from project to market finance, facilitating collaboration along the value chain, and provision of leadership and advocacy to address issues at governance level,” Woltering explains. This, Van Loon adds, demonstrates a need for the inclusion of properly planned exit strategies from projects, as well as a degree of flexibility during the project development phase.

In all three regions, the supply of appropriate mechanization services is struggling to meet demand and few solutions have been found to support the transition from project to market finance. Continued capacity development is required at all stages of the value chain to ensure the provision of high-quality services and it has been suggested that incentivizing potential clients to access mechanization services and linking service providers with machinery dealers and mechanics might produce more satisfying results than simply supporting equipment purchases.

Smartphones drive data collection revolution, boost climate-smart agriculture in Bangladesh

Agricultural research is entering a new age in Bangladesh. The days, months and years it takes to collect farm data with a clipboard, paper and pen are nearing their end.

Electronic smartphones and tablets are gaining ground, used by researchers, extension workers and farmers to revolutionize the efficiency of data collection and provide advice on best-bet practices to build resilient farming systems that stand up to climate change.

Digital data collection tools are crucial in today’s ‘big data’ driven agricultural research world and are fundamentally shifting the speed and accuracy of agricultural research, said Timothy Krupnik, Senior Scientist and Systems Agronomist at the International Maize and Wheat Improvement Center (CIMMYT).

“Easy-to-use data collection tools can be made available on electronic tablets for surveys. These allow extension workers to collect data from the farm and share it instantaneously with researchers,” he said.

“These tools allow the regular and rapid collection of data from farmers, meaning that researchers and extension workers can get more information than they would alone in a much quicker time frame.”

“This provides a better picture of the challenges farmers have, and once data are analyzed, we can more easily develop tailored solutions to farmers’ problems,” Krupnik explained.

Through the USAID and Bill and Melinda Gates supported Cereal Systems Initiative for South Asia (CSISA), and the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS) supported Big Data Analytics for Climate-Smart Agriculture in South Asia projects, 125 Department of Agricultural Extension (DAE) agents were trained throughout Bangladesh to use tablets to gather agronomic information from rice and wheat farmers.

It is the first time extension workers have been involved in data collection in the country. Since the pilot began in late 2019, extension workers have collected data from over 5,000 farmers, with detailed information on climate responses, including the management of soil, water and variety use to understand what drives productivity. The DAE is enthused about learning from the data, and plans to collect information from 7,000 more farmers in 2020.

Bangladesh’s DAE is directly benefiting through partnerships with expert national and international researchers developing systems to efficiently collect and analyze massive amounts of data to generate relevant climate-smart recommendations for farmers, said the department Director General Dr. M. Abdul Muyeed.

For the first time widespread monitoring examines how farmers are coping with climate stresses, and agronomic data are being used to estimate greenhouse gas emissions from thousands of individual farmers. This research and extension partnership aims at identifying ways to mitigate and adapt to climate change, he explained.

“This work will strengthen our ability to generate agriculturally relevant information and increase the climate resilience of smallholder farmers in Bangladesh,” Dr. Muyeed said.

Next-gen big data analysis produces best-bet agricultural practices

“By obtaining big datasets such as these, we are now using innovative research methods and artificial intelligence (AI) to examine patterns in productivity, the climate resilience of cropping practices, and greenhouse gas emissions. Our aim is to develop and recommend improved agricultural practices that are proven to increase yields and profitability,” said Krupknik.

The surveys can also be used to evaluate on-farm tests of agricultural technologies, inform need-based training programs, serve local knowledge centers and support the marketing of locally relevant agricultural technologies, he explained.

“Collecting farm-specific data on greenhouse gas emissions caused by agriculture and recording its causes is a great step to develop strategies to reduce agriculture’s contribution to climate change,” added Krupnik.

‘Sharing’ or ‘sparing’ land?

Written by Rodrigo Ordóñez on . Posted in Blogs. 4 Comments on ‘Sharing’ or ‘sparing’ land?

Any fifth grader is familiar with the Cretaceous-Tertiary mass extinction, which saw dinosaurs — and three quarters of all species alive at that time — disappear from Earth, probably after it was struck by a very large asteroid. However, few people are aware the planet is currently going through a similar event of an equally large magnitude: a recent report from the World Wide Fund for Nature highlighted a 60% decline in the populations of over 4,000 vertebrate species monitored globally since 1970. This time, the culprit is not an asteroid, but human beings. The biggest threat we represent to other species is also the way we meet one of our most fundamental needs: food production.

As a response, scientists, particularly ecologists, have looked for strategies to minimize trade-offs between agriculture and biodiversity. One such strategy is “land sparing,” also known as the “Borlaug effect.” It seeks to segregate production and conservation and to maximize yield on areas as small as possible, sparing land for nature. Another strategy is “land sharing” or “wildlife-friendly farming,” which seeks to integrate production and conservation in the same land units and make farming as benign as possible to biodiversity. It minimizes the use of external inputs and retains unfarmed patches on farmland.

A heated debate between proponents of land sparing and proponents of land sharing has taken place over the past 15 years. Most studies, however, have found land sparing to lead to better outcomes than land sharing, in a range of contexts. With collaborators from CIFOR, UBC and other organizations, I hypothesized that this belief was biased because researchers assessed farming through a narrow lens, only looking at calories or crop yield.

Many more people today suffer from hidden hunger, or lack of vitamins and minerals in their diets, than lack of calories. Several studies have found more diverse and nutritious diets consumed by people living in or near areas with greater tree cover as trees are a key component of biodiversity. However, most of these studies have not looked at mechanisms explaining this positive association.

Forests for food

Studying seven tropical landscapes in Bangladesh, Burkina Faso, Cameroon, Ethiopia, Indonesia, Nicaragua and Zambia, we found evidence that tree cover directly supports diets in four landscapes out of seven. This may be through the harvest of bushmeat, wild fruits, wild vegetables and other forest-sourced foods. The study further found evidence of an agroecological pathway — that forests and trees support diverse crop and livestock production through an array of ecosystem services, ultimately leading to improved diets — in five landscapes out of seven. These results clearly demonstrate that although land sparing may have the best outcomes for biodiversity, it would cut off rural households from forest products such as forest food, firewood and livestock feed. It would also cut off smallholder farms from ecosystem services provided by biodiversity, and smallholders in the tropics tend to depend more on ecosystem services than on external inputs.

In Ethiopia, previous research conducted by some of the same authors has demonstrated that multifunctional landscapes that do not qualify as land sparing nor as land sharing may host high biodiversity whilst being more productive than simpler landscapes. They are more sustainable and resilient, provide more diverse diets and produce cereals with higher nutritional content.

The debate on land sparing vs. sharing has largely remained confined to the circles of conservation ecologists and has seldom involved agricultural scientists. As a result, most studies on land sparing vs. sharing have focused on minimizing the negative impact of farming on biodiversity, instead of looking for the best compromises between agricultural production and biodiversity conservation.

To design landscapes that truly balance the needs of people and nature, it is urgent for agronomists, agricultural economists, rural sociologists and crop breeders to participate in the land sparing vs. sharing debate.

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 publications: Do market shocks generate gender-differentiated impacts?

Written by Emma Orchardson on . Posted in Publications.

Female-headed households are likely to experience higher welfare losses due to commodity price hikes than their male-headed counterparts, as they tend to spend a larger percentage of their income on food items. However, the full extent of this impact of market has not been widely examined in the empirical literature.

Applying the difference-in-difference estimation procedure to data collected from more than 22,000 households in Bangladesh in 2005 and 2010, researchers at the International Maize and Wheat Improvement Center (CIMMYT) set out to examine the gender-differentiated impacts of the commodity price hikes during the food price crisis of 2008 on food and non-food consumption behavior based on the sex of the household head.

They found that, in general, the commodity price hikes had more adversely affected female-headed households, which reduced their expenditure on food and non-food items such as cereals and education at a greater rate than their male-headed counterparts did.

However, their study also reveals that the welfare impacts on these households varied greatly depending on socio-economic conditions. Results showed that households headed by women who were relatively better educated, who owned larger pieces of land and received remittances were buffered to a certain extent and their expenditure was affected less.

Understanding these buffering factors, the authors argue, is crucial when designing policy interventions in developing countries. The study provides a number of recommendations for government and international donor agencies to help female-headed households better cope with market shocks. For example, they could improve the reach of general education, increase women’s access to land and agricultural assets and remove barriers to the in-flow of remittances for female-headed households. Extending the reach of social protection and microcredit programs could further complement market shock buffering capacity, as could providing targeted capital.

New publications: Exploring how women seize control of wheat–maize technologies in Bangladesh

Written by Matthew O'Leary on . Posted in Publications.

A new study published in the Canadian Journal of Development Studies shows how some of Bangladesh’s indigenous women are overcoming social norms and institutional biases to gain direct access to maize and wheat agricultural innovations through developing women-led agricultural organizations, which benefit low-income Muslim women members as well.

Agriculture is important to Bangladesh’s economy and employs a large percentage of the male and female population as farmers, hired labor, and decision-makers. Bangladesh also has a positive policy commitment to gender equality. The UN Sustainable Development Goals are embedded into the country’s national growth plans, including a strong commitment to Goal 5, Gender Equality, and Goal 10, Reduced Inequalities.

However, this new study shows that agricultural innovation programs are primarily directed at middle-income male farmers. Institutional biases in agricultural partners — extension officers, research organizations, policymakers, private sector partners and others — can hamper indigenous peoples and women from participating in wheat–maize innovation processes, as they rarely meet the requisite criteria: sufficient land and social capital. In addition, their participation in markets varies according to their socioeconomic location in society.

Drawing on GENNOVATE case studies, the authors provide insights into how overlapping layers of disadvantage are being challenged in one community in northern Bangladesh.

Indigenous Santal women in the community are active in agriculture, both in the field and in decision-making, but are often marginalized by agricultural partners. Through mobilizing themselves organizationally into a woman-led agricultural organization, they have provided a forum for the delivery of technical training. This process has encouraged low-income Muslim women — who work in the field but are also marginalized by agricultural partners — to join the organization and benefit from training as well.

The findings provide insights into how agricultural research partners can work to strengthen the contribution and voices of the women who have long experienced differing forms of marginalization and to support their efforts to secure technical training.

The data used in this article is derived from GENNOVATE (Enabling Gender Equality in Agricultural and Environmental Innovation), a global research initiative supported by the Bill & Melinda Gates Foundation. This is a cross-CGIAR initiative examining how interactions between gender norms, agency and other contextual factors shape access to, adoption of and benefits from agricultural innovations in rural communities worldwide.

Climate Services for Resilient Development in South Asia (CSRD)

Written by Rodrigo Ordóñez on . Posted in Uncategorized.

Climate Services for Resilient Development (CSRD) is a global partnership that connects climate and environmental science with data streams to generate decision support tools and training for decision-makers in developing countries. Translating complex climate information into easy to understand actionable formats to spread awareness in the form of climate services is core to CSRD’s mission. CSRD works across South Asia (with emphasis on Bangladesh), the Horn of Africa (Ethiopia), and in South America (Colombia) to generate and provide timely and useful climate information, decision tools and services. In South Asia, CSRD focusses the development, supply and adaptation of agricultural climate services to reduce vulnerability by increasing resiliency in smallholder farming systems. These goals are strategically aligned with the Global Framework for Climate Services.

Project description

CSRD in South Asia aims to have the impact by increasing climate resilient farm management, indicated by increased use of climate services and climate information to inform farmers on how to better manage their production systems.  CSRD also aims to develop and validate models for agricultural climate services that can be replicated in other regions with similar farming systems and climate risks, while also fine-tuning weather and climate advisories to be most useful to farmers’ decision-making. A series of sustained contributions to CSRD’s Action and Learning Framework Pillars 1-4, detailed below, are envisioned as major project outcomes:

  • Pillar 1: Create the solution space:
    CSRD works to establish a problem-focus, to engage key stakeholders, to create a platform for sustained communication and collaboration, and to build synergies among relevant programs.
  • Pillar 2: Utilize quality data, products, and tools
    CSRD provides access to useful and available information and technology, and to develop tailored products and services responsive to problem-specific needs.
  • Pillar 3: Build capacities and platforms
    CSRD supports the use of targeted products and services, and to promote sustainability, scalability, and replicability.
  • Pillar 4: Build knowledge
    A key goal of CSRD’s work is to identify and promote good practices among the global climate services community and to support research efforts and innovation that increase the effectiveness of climate services.

Outputs

CSRD in South Asia will ultimately generate the following broad outputs and services:

To mitigate the food security and economic risks of South Asia’s frequent and intense droughts, scientists and policymakers from the South Asian Association for Regional Cooperation (SAARC), the International Centre for Integrated Mountain Development (ICIMOD) and the International Maize and Wheat Improvement Center (CIMMYT) recently joined forces to launch an innovative decision support and agricultural planning system that combines remote sensing and  climate data analysis for drought monitoring and early warning.

The Regional Drought Monitoring and Outlook System application was unveiled during a workshop to train experts and policymakers in its use at relevant regional and national institutes in Islamabad, Pakistan, from July 29 to August 1, 2019. The Regional Drought Monitoring and Outlook System is the product of an ICIMOD-CIMMYT partnership through the United States Agency for International Development (USAID) and the National Aeronautics and Space Administration (NASA) supported SERVIR Hindu Kush Himalaya (HKH) programme, in collaboration with Climate Service for Resilient Development (CSRD), led by ICIMOD and CIMMYT, respectively.

“Commonly associated with epic flooding, particularly in the enormous breadbasket region known as the Indo-Gangetic Plains that extends across Pakistan, India, southern Nepal, and Bangladesh, the region also faces droughts driven by rising temperatures and erratic rainfall and which threaten crops, food security, and livelihoods,” said Faisal Mueen Qamer, Remote Sensing Specialist of ICIMOD, which helped develop the system and organize the workshop.

“We expect the system to foster resilience in South Asian agriculture, while supporting future institutional frameworks and policies for farm compensation and adaptation, through decision makers’ access to timely and action-oriented information,” Qamar explained.

With a growing population of 1.6 billion people, South Asia hosts 40% of the world’s poor and malnourished on just 2.4% of its land. A 2010 study found a linear drop of 7.5% in rainfall in South Asia from 1900 to 2005.

“Shrinking glaciers, water scarcity, rising sea levels, shifting monsoon patterns, and heat waves place considerable stress on South Asian countries, whose primary employment sector remains agriculture,” said Mohammad Faisal, Director General for South Asia at Pakistan’s Ministry of Foreign Affairs, during the workshop opening.

Media reports in early 2019 documented displacement and hunger from Pakistan’s worst drought in years.

Raising awareness about drought and its mitigation

Twenty-three participants from six South Asia countries plus five expert instructors attended the workshop, which offered presentations and hands-on training on a suite of applications and associated data analysis tools, including the South Asian Land Data Assimilation System (SALDAS), the Regional Drought Explorer, and the National Drought Early Warning System.

Muhammad Azeem Khan, Member of the Food Security & Climate Change at the Planning Commission of Pakistan, said the scale of present and future climate challenges is clearly evident.

“In Pakistan, we regularly see parts of the country in the grip of severe drought, while others have flash floods,” Khan commented during the workshop closing, while commending its organizers. “Frequent drought diminishes agricultural production and food security, especially for people in rural areas. Effectively managing the impacts of climate change requires a response that builds and sustains South Asia’s social, economic, and environmental resilience, as well as our emergency response capacity.”

Through CSRD, a global partnership that connects climate and environmental science with data streams to generate decision support tools and training for decision-makers in developing countries, CIMMYT helped extend the Regional Drought Monitoring and Outlook System to Bangladesh, from its original coverage of Afghanistan, Nepal, and Pakistan.

“Translating complex climate information into easy-to-understand and actionable formats is core to CSRD’s mission and helps spread awareness about climate challenges,” said Tim Krupnik, CIMMYT cropping systems agronomist based in Bangladesh. “This consortium provides strength and technical expertise to develop relevant climate products, including decision-support information for farmers and other stakeholders, thus fostering resilience to climate-related risks.”

New publications: A study of water markets in Bangladesh

Written by Emma Orchardson on . Posted in Publications. 3 Comments on New publications: A study of water markets in Bangladesh

Domestic rice and wheat production in Bangladesh has more than doubled in the last 30 years, despite declining per capita arable land. The fact that the country is now almost self-sufficient in staple food production is due in large part to successful and rapid adoption of modern, high-yielding crop varieties. This has been widely documented, but less attention has been paid to the contribution of small-scale irrigation systems, whose proliferation has enabled double rice cropping and a competitive market system in which farmers can purchase irrigation services from private pump owners at affordable rates.

However, excess groundwater abstraction in areas of high shallow tube-well density and increased fuel costs for pumping have called into question the sustainability of Bangladesh’s groundwater irrigation economy. Cost-saving agronomic methods are called for, alongside aligned policies, markets, and farmers’ incentives.

A recent study by researchers at the International Maize and Wheat Improvement Center (CIMMYT) examines the different institutions and water-pricing methods for irrigation services that have emerged in Bangladesh, each of which varies in their incentive structure for water conservation, and the level of economic risk involved for farmers and service providers.

Using primary data collected from 139 irrigation service providers and 556 client-farmers, the authors assessed the structure of irrigation service types as well as the associated market and institutional dimensions. They found that competition between pump owners, social capital, and social relationship between of pump owners and client farmers, significantly influence the structure of irrigation services and irrigation water pricing methods. Greater competition between pump owners, for instance, increases the likelihood of pay-per-hour services while reducing that of crop sharing arrangements.

Based on these and other findings, authors made policy recommendations for enhancing irrigation services and sustainability in Bangladesh. As Bangladesh is already highly successful in terms of the conventional irrigation system, the authors urge taking it to the next level for sustainability and efficiency.

Currently Bangladesh’s irrigation system is based on centrifugal pumps and diesel engines. The authors suggest scaling out the energy efficient axial flow pump, and the alternate wetting and drying system for water conservation and irrigation efficiency. They also recommend further investment in rural electrification to facilitate the use of electric motors, which can reduce air pollution by curbing dependency on diesel engines.

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.

The case for rushing farmer access to BARI Gom 33

In 2016, the emergence of wheat blast, a devastating seed- and wind-borne pathogen, threatened an already precarious food security situation in Bangladesh and South Asia.

In a bid to limit the disease’s impact in the region, the Bangladesh Agricultural Research Institute (BARI) collaborated with the International Maize and Wheat Improvement Center (CIMMYT) and researchers from nearly a dozen institutions worldwide to quickly develop a long-term, sustainable solution.

The result is BARI Gom 33, a new blast-resistant, high-yielding, zinc-fortified wheat variety, which Bangladesh’s national seed board approved for dissemination in 2017. In the 2017-18 season, the Bangladesh Wheat Research Council provided seed for multiplication and the country’s Department of Agricultural Extension established on-farm demonstrations in blast prone districts.

However, the process of providing improved seed for all farmers can be a long one. In a normal release scenario, it can take up to five years for a new wheat variety to reach those who need it, as nucleus and breeder seeds are produced, multiplied and certified before being disseminated by extension agencies. Given the severity of the threat to farmer productivity and the economic and nutritional benefits of the seed, scientists at CIMMYT argue that additional funding should be secured to expedite this process.

According a new study on the economic benefits of BARI Gom 33, 58 percent of Bangladesh’s wheat growing areas are vulnerable to wheat blast. The rapid dissemination of seed can help resource-poor farmers better cope with emerging threats and changing agro-climatic conditions, and would play a significant role in combatting malnutrition through its increased zinc content. It could also have a positive effect on neighboring countries such as India, which is alarmingly vulnerable to wheat blast.

“Our simulation exercise shows that the benefits of disseminating BARI Gom 33 far exceed the seed multiplication and dissemination costs, which are estimated at around $800 per hectare,” explains Khondoker Mottaleb, CIMMYT socioeconomist and lead author of the study. Even in areas unaffected by wheat blast, scaling out BARI Gom 33 could generate a net gain of $8 million for farmers due to its 5 percent higher average yield than other available varieties. These benefits would nearly double in the case of an outbreak in blast-affected or blast-vulnerable districts.

Based on these findings, the authors urge international development organizations and donor agencies to continue their support for BARI Gom 33, particularly for government efforts to promote the blast-resistant variety. The minimum seed requirement to begin the adoption and diffusion process in the 2019-20 wheat season will be 160 metric tons, which will require an initial investment of nearly $1 million for seed multiplication.
