Article
Full-text available
Rice production has increased significantly with the efforts of international research centers and national governments in the past five decades. Nonetheless, productivity improvement still needs to accelerate in the coming years to feed the growing population that depends on rice for calories and nutrients. This challenge is compounded by the incr...

Fish is a major source of food and nutritional security for subsistence communities in developing countries, it also has linkages with the economic and supply-chain dimensions of these countries. Burgeoning literature has revealed the adverse impacts of COVID-19 on the fisheries and aquaculture sector, which serves as the major source of income and...
Article
Climate change affects crop production through exposure to droughts, floods, pests, and pathogens. To mitigate climate-induced production losses, various stress-tolerant varieties have been developed and adopted in many countries around the globe. We assess the impacts of adopting submergence-tolerant (Sub1) rice varieties on productivity, profit,...

This paper explores coastal rice farmers’ vulnerability, food security and adaptation strategies in response to climate change issues. Survey data were collected from 120 rice farmers from two coastal districts of Bangladesh and analyzed using descriptive statistics t...
Article
Diversifying and intensifying the rice-based cropping systems in the southern coastal zone of Bangladesh is a government priority to meet the food, feed, and fiber demand of an increasing population and changing climate. This study was conducted for three years (2016–2019) in Polder 30 located in southwest coastal zone of Bangladesh with five cropp...
Article
Full-text available
Rapid expansion of groundwater use for irrigation for dry season rice production in Bangladesh has led to overuse, deterioration of groundwater quality, increased cost of irrigation, and higher greenhouse gas emissions. The divergence between marginal private and social cost of irrigation due to market failures in the presence of these externalitie...

Policy brief on the impact of COVID-19 on the rice value chain in Asia. This work was based on interviews with rice value chain actors in selected countries in South and Southeast Asia
Article
Most of the lands of the southern coastal zone of Bangladesh are protected from tidal flooding and storm surges by embankments constructed during the 1960s and 1970s, creating polders. Sluice gates in the embankments connect the canals (former river distributaries) inside the polders to the surrounding rivers, providing the opportunity for water in...
Conference Paper
While most of the food in Asia is produced by aged farmers who are less likely to adopt technologies for a sustainable increase of the productivity required to keep the world food secure, yet around the world, few young people see a future for themselves in agriculture. Similar scenario in Bangladesh where there is a general perception that young g...

p>The study was carried out to investigate the patterns and extent of livelihood diversification in rural Bangladesh. It also identified the major factors affecting extent of livelihood diversification. The study drew a random sample of 500 rural farm households in Bangladesh through a multi-stage sampling technique. The primary data were collected...
Conference Paper
Full-text available
This study examines the adoption of submergence-tolerant (Sub1) rice varieties (BRRI dhan51, BRRI dhan52, BINA Dhan 11, and BINA Dhan 12), grown in the Aman season (July-November) in northwest Bangladesh, using data obtained from more than 1,100 farm households. The impacts of these varietal adoptions on profit from rice production and household co...
Chapter
The Indian rice sector is transforming in tandem with rapid social and economic changes. This chapter examines the ongoing structural transformation in India’s rice economy and draws conclusions to enable the development of a vibrant and sustainable rice value chain. The analysis is based on a descriptive analysis of secondary data and a literature...
Conference Paper
Product profile is the nobel approach to guide rice breeding priorities for market-driven and targeted rice varietal development. It is also useful to donors in making rice breeding programs more cost-efficient, market-driven, client- and product-oriented, and forward-looking. Rice breeders should take into account the documented traits coming from...
Article

This article examines the transformation from rice farming to commercial aquaculture and its implications for gender roles and relations, women’s access to and control over resources, household food security, and livelihood. Primary data collected from 400 sample households located across 10 villages in northern and southern Bangladesh were used fo...
Article
Full-text available
Diversification of livelihood activities minimizes households' vulnerability to shocks by reducing income variability. Livelihoods of rural Bangladesh is encompass both farm and non-farm activities. This study investigated the patterns and extent of diversification of livelihoods in rural areas of Bangladesh. The study drew a random sample of 500 r...

Agriculture provides livelihood for over 60% of Bangladesh’s population. It is pivotal to provide food and income for the rural poor. At the same time, it is also crucial to reduce agriculture’s high population density. Powerful social, economic, and natural forces are driving changes in agricultural systems. The agriculture sector must respond to...

Bangladesh’s agriculture is rapidly transforming due to social and economic development. These transformations have implications on resource use, food production, and technology development. This paper presents key long-term transformation in Bangladesh’s agriculture.
Article
Rice is the major staple food in Bangladesh, contributing 71% of total calorie supply, 58% of total protein intake, and 15% of rural household income. More than half of Bangladeshi households are net buyers of rice. Poor households spend 40% of their food expenditure on rice. By reducing real income and purchasing power, a rice price inflation wors...
Conference Paper
Full-text available
Bangladesh has made remarkable progress in rice production in the past three decades with production growing at 3% per year, leading to self-sufficiency in rice for the first time in 2000 for its 150 million people. But now it faces challenges of feeding an additional 1.8 million mouth each year with declining land, water, labor, and other producti...
Article
We assess the effects of the dramatic rise in agricultural commodity prices during 2007–2008 on income dynamics and poverty among rural households in Bangladesh. A unique panel data set allows us to put the effects of recent events in the context of long-run trends in income and poverty. We use data from a nationally representative longitudinal sur...

Drought is a major constraint to rice production in Asia. Drought occurs frequently and is one of the major reasons for wide fluctuations in rainfed production. The economic cost of drought estimated in this study was found to be substantial in rainfed areas of eastern India. The economic cost of drought depends largely on the frequency and coverag...

Drought is a major constraint affecting rice production, especially in rainfed areas of Asia. Despite its importance in rice-growing areas, the magnitude of economic losses arising from drought, its impact on farm households, and farmers' drought coping mechanisms are poorly understood. This article provides insights into these aspects of drought b...
