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.

A delegation of the Indonesian Agency for Agricultural Research and Development (IAARD) visited the International Maize and Wheat Improvement Center (CIMMYT) to reaffirm their research partnership. Led by the Director General of IAARD, Fadjry Djufry, a group of Indonesian researchers and leaders visited CIMMYT on August 28 and August 29.

CIMMYT and IAARD have collaborated on research since 1981, when an Indonesian researcher participated in CIMMYT trainings. Since 1995, CIMMYT has worked with Indonesia through joint research and donations of inbred lines. CIMMYT has helped the Indonesian Cereals Research Institute (ICERI) in establishing infrastructure for a drought-tolerant nursery and has sponsored ICERI researchers to attend international scientific meetings. The CIMMYT-organized Asian Maize Biotechnology Network supported a satellite molecular laboratory for ICERI.

During the visit, the Indonesian delegation signed a memorandum of understanding with CIMMYT. Visitors also attended presentations on CIMMYT’s progress and strategy, toured the germplasm bank, visited the maize nutrition quality lab, and did a field visit to learn about sustainable intensification and climate change adaptation.

After CIMMYT director general Martin Kropff gave an overview of CIMMYT, the IAARD delegation presented their work and innovations to increase maize and wheat production. Indonesian researchers have released high yielding maize varieties, functional maize varieties and hybrid maize varieties. Farmers are intercropping maize, rice and soybeans. Post-harvest technology, mechanization and mapping have contributed to maize productivity.

Scientists use DNA fingerprinting to gauge the spread of modern wheat in Afghanistan

Written by Mike Listman on . Posted in Press releases.

Wheat is Afghanistan’s number-one staple crop, but the country doesn’t grow enough and must import millions of tons of grain each year to satisfy domestic demand.
Wheat is Afghanistan’s number-one staple crop, but the country does not grow enough and must import millions of tons of grain each year to satisfy domestic demand.

Despite the severe social and political unrest that constrain agriculture in Afghanistan, many farmers are growing high-yielding, disease resistant varieties developed through international, science-based breeding and made available to farmers as part of partnerships with national wheat experts and seed producers.

These and other findings have emerged from the first-ever large-scale use of DNA fingerprinting to assess Afghanistan farmers’ adoption of improved wheat varieties, which are replacing less productive local varieties and landraces, according to a paper published yesterday in the science journal BMC Genomics.

The study is part of an activity supported between 2003 and 2018 by the Australian Department of Foreign Affairs and Trade, through which the Agricultural Research Institute of Afghanistan and the International Maize and Wheat Improvement Center (CIMMYT) introduced, tested, and released improved wheat varieties.

“As part of our study, we established an extensive ‘reference library’ of released varieties, elite breeding lines, and Afghan wheat landraces,” said Susanne Dreisigacker, wheat molecular breeder at CIMMYT and lead author of the new paper.

“We then compared wheat collected on farmers’ fields with the reference library. Of the 560 wheat samples collected in 4 provinces during 2015-16, farmers misidentified more than 40%, saying they were of a different variety from that which our DNA analyses later identified.”

Wheat is the most important staple crop in Afghanistan — more than 20 million of the country’s rural inhabitants depend on it — but wheat production is unstable and Afghanistan has been importing between 2 and 3 million tons of grain each year to meet demand.

Over half of the population lives below the poverty line, with high rates of malnutrition. A key development aim in Afghanistan is to foster improved agronomic practices and the use of high quality seed of improved wheat varieties, which together can raise yields by over 50%.

“Fungal diseases, particularly yellow rust and stem rust, pose grave threats to wheat in the country,” said Eric Huttner, research program manager for crops at the Australian Centre for International Agricultural Research (ACIAR) and co-author of the present paper. “It’s crucial to know which wheat varieties are being grown where, in order to replace the susceptible ones with high-performing, disease resistant varieties.”

Varietal adoption studies typically rely on questionnaires completed by breeders, extension services, seed producers, seed suppliers, and farmers, but such surveys are complicated, expensive, and often inaccurate.

“DNA fingerprinting resolves uncertainties regarding adoption and improves related socioeconomic research and farm policies,” Huttner explained, adding that for plant breeding this technology has been used mostly to protect intellectual property, such as registered breeding lines and varieties in more developed economies.

This new study was commissioned by ACIAR as a response to a request from the Government of Afghanistan for assistance in characterizing the Afghan wheat gene bank, according to Huttner.

“This provided the reference library against which farmers’ samples could be compared,” he explained. “Accurately identifying the varieties that farmers grow is key evidence on the impact of introducing improved varieties and will shape our future research

Joint research and development efforts involving CIMMYT, ACIAR, the Food and Agriculture Organization (FAO) of the United Nations, the International Centre of Agricultural Research in Dry Areas (ICARDA), French Cooperation, and Afghanistan’s Ministry of Agriculture, Irrigation and Livestock (MAIL) and Agricultural Research Institute (ARIA) have introduced more than 400 modern, disease-resistant wheat varieties over the last two decades. Nearly 75% of the wheat grown in the areas surveyed for this study comes from these improved varieties.

“New sequencing technologies are increasingly affordable and their cost will continue to fall,” said Dreisigacker. “Expanded use of DNA fingerprinting can easily and accurately identify the wheat cultivars in farmers’ fields, thus helping to target breeding, agronomy, and development efforts for better food security and farmer livelihoods.”

Nepal’s seed sector partners join forces to realize the National Seed Vision 2013-2025

Written by Rodrigo Ordóñez on . Posted in Features.

Access to affordable quality seed is one of the prerequisites to increase agricultural production and improve the livelihoods of Nepali farmers. However, there are significant challenges to boost Nepal’s seed industry and help sustainably feed a growing population.

Six years ago, Nepal launched its National Seed Vision 2013-2025. This strategic plan aims at fostering vibrant, resilient, market-oriented and inclusive seed systems in public-private partnership modalities, to boost crop productivity and enhance food security.

The Nepal Seed and Fertilizer (NSAF) project, led by the International Maize and Wheat Improvement Center (CIMMYT), is supporting the government to enhance national policies and guidelines, and private seed companies to build competitive seed businesses and hybrid seed production.

Quality seed can increase crop yield by 15-20%. However, there are critical challenges hindering the growth of Nepal’s seed industry. Existing seed replacement rate for major cereals is low, around 15%. About 85% of Nepali farmers are unable to access recently developed improved seeds — instead, they are cultivating decades-old varieties with low yield and low profits. Some of the factors limiting the development of seed systems are the high cost of seed production and processing, the limited reach of mechanization, and the low use of conservation agriculture practices.

The demand for hybrid seeds in Nepal is soaring but research in variety development is limited. Most of the country’s supply comes from imports.

In collaboration with the Nepal Agricultural Research Council (NARC), the NSAF project team is working with seed companies and cooperatives to scale hybrid seed production of maize, tomato and rice. Through this project, CIMMYT collaborated with the Seed Quality Control Center (SQCC) and national commodity programs of the NARC to draft the first hybrid seed production and certification guidelines for Nepal to help private seed companies produce and maintain standards of hybrid seeds.

Extension and promotion activities are essential to bring improved seed varieties to farmers. Standard labelling and packaging also needs to be strengthened.

A joint effort

CIMMYT and its partners organized a two-day workshop to review the progress of the National Seed Vision. The event attracted 111 participants from government institutions, private companies and development organizations engaged in crop variety development, seed research, seed production and dissemination activities.

In the opening remarks, Yubak Dhoj G.C., Secretary of Nepal’s Ministry of Agriculture and Livestock Development, addressed the seed sector scenario and its challenges. He stressed the importance of collaboration among seed stakeholders to meet the targets of the National Seed Vision in the next six years.

During the technical sessions, Madan Thapa, Chief of the SQCC, analyzed the current status of the National Seed Vision and highlighted the challenges as well as the opportunities to realize it.

Laxmi Kant Dhakal, Chairperson of the Seed Entrepreneurs Association of Nepal (SEAN) emphasized the importance of private sector engagement and other support areas to strengthen seed production and marketing of open-pollinated varieties and hybrids.

Tara Bahadur Ghimire, Principal Scientist at NARC, gave an overview of the status of NARC varieties, source seed and resource allocation.

Dila Ram Bhandari, former Chief of SQCC, led a discussion around the assumptions and expectations that arose while developing the National Seed Vision.

Technical leads of maize, rice, wheat and vegetables presented a road map on hybrid variety development and seed production in line with the National Seed Vision’s targets for each crop.

“A large quantity of hybrid seeds, worth millions of dollars, is being imported into Nepal each year,” explained AbduRahman Beshir, Seed Systems Lead of CIMMYT’s NSAF project. “However, if stakeholders work together and strengthen the local seed system, there is a huge potential in Nepal not only to become self-sufficient but also to export good quality hybrid seeds in the foreseeable future. Under the NSAF project we are witnessing a few seed companies that have initiated hybrid seed production of maize and tomato.”

In one of the exercises, workshop participants were divided in groups and examined different topics related to the realization of the National Seed Vision. They looked at genetic resources, hybrid and open-pollinated variety development, source seed production and supply, private sector engagement and marketing, seed extension and varietal adoption by farmers, seed quality control services, and roles of research partners and other stakeholders. The groups presented some of the major challenges and opportunities related to these topics, as well as recommendations, which will be documented and shared.

The outcomes of this mid-term review workshop will inform policy and guide the discussions at the upcoming International Seed Conference to be held in early September 2019.

Regulating hybrid seed production

At the workshop, participants thoroughly discussed the draft hybrid seed production and certification guidelines, developed under the NSAF project.

The guidelines are the first of their kind in Nepal and essential to achieve the targets of the National Seed Vision, by engaging the private sector in hybrid seed production.

Hari Kumar Shrestha, CIMMYT’s Seed Systems Officer, and other seed experts from the SQCC presented the main features and regulatory implications of the guidelines.

After the workshop, the guidelines were sent to the National Seed Board for approval.

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.”

A research paper published in the world’s leading scientific journal, Science Magazine, indicates that using the Happy Seeder agriculture technology to manage rice residue has the potential of generating 6,000-11,500 Indian rupees (about US$85-160) more profits per hectare for the average farmer. The Happy Seeder is a tractor-mounted machine that cuts and lifts rice straw, sows wheat into the soil, and deposits the straw over the sown area as mulch.

The paper “Fields on fire: Alternatives to crop residue burning in India” evaluates the public and private costs and benefits of ten alternate farming practices to manage rice residue, including burn and non-burn options. Happy Seeder-based systems emerge as the most profitable and scalable residue management practice as they are, on average, 10%–20% more profitable than burning. This option also has the largest potential to reduce the environmental footprint of on-farm activities, as it would eliminate air pollution and would reduce greenhouse gas emissions per hectare by more than 78%, relative to all burning options.

This research aims to make the business case for why farmers should adopt no-burn alternative farming practices, discusses barriers to their uptake and solutions to increase their widespread adoption. This work was jointly undertaken by 29 Indian and international researchers from The Nature Conservancy, the International Maize and Wheat Improvement Centre (CIMMYT), the University of Minnesota, the Indian Council of Agricultural Research (ICAR), the Borlaug Institute for South Asia (BISA) and other organizations.

Every year, some 23 million tonnes of rice residue is burnt in the states of Haryana, Punjab and Western Uttar Pradesh, contributing significantly to air pollution and short-lived climate pollutants. In Delhi NCR, about half the air pollution on some winter days can be attributed to agricultural fires, when air quality level is 20 times higher than the safe threshold defined by WHO. Residue burning has enormous impacts on human health, soil health, the economy and climate change.

“Despite its drawbacks, a key reason why burning continues in northwest India is the perception that profitable alternatives do not exist. Our analysis demonstrates that the Happy Seeder is a profitable solution that could be scaled up for adoption among the 2.5 million farmers involved in the rice-wheat cropping cycle in northwest India, thereby completely eliminating the need to burn. It can also lower agriculture’s contribution to India’s greenhouse gas emissions, while adding to the goal of doubling farmers income,” says Priya Shyamsundar, Lead Economist at The Nature Conservancy and one of the lead authors of the paper.

“Better practices can help farmers adapt to warmer winters and extreme, erratic weather events such as droughts and floods, which are having a terrible impact on agriculture and livelihoods. In addition, India’s efforts to transition to more sustainable, less polluting farming practices can provide lessons for other countries facing similar risks and challenges,” explains M.L. Jat, CIMMYT cropping systems specialist and a co-author of the study.

“Within one year of our dedicated action using about US$75 million under the Central Sector Scheme on ‘Promotion of agriculture mechanization for in-situ management of crop residue in the states of Punjab, Haryana, Uttar Pradesh and NCT of Delhi,’ we could reach 0.8 million hectares of adoption of Happy Seeder/zero tillage technology in the northwestern states of India,” said Trilochan Mohapatra, director general of the Indian Council of Agricultural Research (ICAR). “Considering the findings of the Science article as well as reports from thousands of participatory validation trials, our efforts have resulted in an additional direct farmer benefit of US$131 million, compared to a burning option,” explained Mohapatra, who is also secretary of India’s Department of Agricultural Research and Education.

The Government of India subsidy in 2018 for onsite rice residue management has partly addressed a major financial barrier for farmers, which has resulted in an increase in Happy Seeder use. However, other barriers still exist, such as lack of knowledge of profitable no-burn solutions and impacts of burning, uncertainty about new technologies and burning ban implementation, and constraints in the supply-chain and rental markets. The paper states that NGOs, research organizations and universities can support the government in addressing these barriers through farmer communication campaigns, social nudging through trusted networks and demonstration and training. The private sector also has a critical role to play in increasing manufacturing and machinery rentals.

A new economic study in the journal Science shows that thousands of farmers in northern India could increase their profits if they stop burning their rice straw and adopt no-till practices to grow wheat. Alternative farming practices could also cut farmers’ greenhouse gas emissions from on-farm activities by as much as 78% and help lower air pollution in cities like New Delhi.

The new study compares the costs and benefits of 10 distinct land preparation and sowing practices for northern India’s rice-wheat cropping rotations, which are spread across more than 4 million hectares. The direct seeding of wheat into unplowed soil and shredded rice residues was the best option — it raises farmers’ profits through higher yields and savings in labor, fuel, and machinery costs.

The study, conducted by a global team of eminent agriculture and environmental scientists, was led by researchers from The Nature Conservancy, the International Maize and Wheat Improvement Center (CIMMYT), the Indian Council of Agricultural Research (ICAR), the Borlaug Institute for South Asia (BISA) and the University of Minnesota.

A burning issue

To quickly and cheaply clear their fields to sow wheat each year, farmers in northern India burn an estimated 23 million tons of straw from their rice harvests. That enormous mass of straw, if packed into 20-kilogram 38-centimeter-high bales and piled on top of each other, would reach a height of over 430,000 kilometers — about 1.1 times the distance to the moon.

Regulations are in place in India to reduce agricultural fires but burning continues because of implementation challenges and lack of clarity about the profitability of alternate, no-burn farming.

Farmers have alternatives, the study shows. To sow wheat directly without plowing or burning rice straw, farmers need to purchase or rent a tractor-mounted implement known as the “Happy Seeder,” as well as attach straw shedders to their rice harvesters. Leaving straw on the soil as a mulch helps capture and retain moisture and also improves soil quality, according to M.L. Jat, CIMMYT Principal Scientist, cropping systems specialist and a co-author of the study.

Win-win

The Science study demonstrates that it is possible to reduce air pollution and greenhouse gas emissions in a way that is profitable to farmers and scalable.

The paper shows that Happy Seeder-based systems are on average 10%–20% more profitable than straw burning options.

“Our study dovetails with 2018 policies put in place by the government of India to stop farmers from burning, which includes a US$166 million subsidy to promote mechanization to manage crop residues within fields,” said Priya Shyamsundar, Lead Economist, Global Science, of The Nature Conservancy and first author of the study.

Shyamsundar noted that relatively few Indian farmers currently sow their wheat using the Happy Seeder but manufacturing of the Seeder had increased in recent years. “Less than a quarter of the total subsidy would pay for widespread adoption of the Happy Seeder, if aided by government and NGO support to build farmer awareness and impede burning.”

“With a rising population of 1.6 billion people, South Asia hosts 40% of the world’s poor and malnourished on just 2.4% of its land,” said Jat, who recently received India’s prestigious Rafi Ahmed Kidwai Award for outstanding and impact-oriented research contributions in natural resource management and agricultural engineering. “Better practices can help farmers adapt to warmer winters and extreme, erratic weather events such as droughts and floods, which are having a terrible impact on agriculture and livelihoods. In addition, India’s efforts to transition to more sustainable, less polluting farming practices can provide lessons for other countries facing similar risks and challenges.”

In November 2017, more than 4,000 schools closed in Delhi due to seasonal smog. This smog increases during October and November when fields are burned. It causes major transportation disruptions and poses health risks across northern India, including Delhi, a city of more than 18 million people.

Some of these problems can be resolved by the use of direct sowing technologies in northwestern India.

“Within one year of our dedicated action using about US$75 million under the Central Sector Scheme on ‘Promotion of agriculture mechanization for in-situ management of crop residue in the states of Punjab, Haryana, Uttar Pradesh and NCT of Delhi,’ we could reach 0.8 million hectares of adoption of Happy Seeder/zero tillage technology in the northwestern states of India,” said Trilochan Mohapatra, director general of the Indian Council of Agricultural Research (ICAR). “Considering the findings of the Science article as well as reports from thousands of participatory validation trials, our efforts have resulted in an additional direct farmer benefit of US$131 million, compared to a burning option,” explained Mohapatra, who is also secretary of India’s Department of Agricultural Research and Education.

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.
