The farmers of Bangladesh face many challenges associated with climate change and increases in population. Rising salinity, waterlogging, flooding and storm surges, coupled with a growing population that is expected to reach 250 million people by the year 2050, have resulted in a decrease in cultivable land for vegetable production. This brief descirbes how vertical agriculture can address the loss of cultivable land by maximizing the space around households and suspending horticulture production along trees, houses and bamboo structures.
Tilapia farming has great potential in Bangladesh. Tilapia promises to become a primary cultured species for freshwater and brackish water ecosystems, and therefore may also be a major source of employment. Bangladesh could become one of the leading Asian countries for tilapia seed production and grow-out farming. This article looks at the current status of Tilapia farming and seed production in Bangladesh.
The marketing system for sea cucumber in South-East Asia is generally inefficient, and marketing channels are multilayered. Information asymmetry encourages proliferation of redundant players in the distribution system, while high transaction costs keep the overall marketing margin high but the price received by collectors low. This paper is limited to establishing the major features of the marketing system for sea cucumber in South-East Asia.
This study presents an overview of the existence and effects of six heavy metals, chromium (Cr), lead (Pb), cadmium (Cd), mercury (Hg), manganese (Mn), and aluminum (Al), in tannery effluents released to the Buriganga River in Dhaka, Bangladesh. The pollutants were found in three different sources, such as effluents from tanneries, contaminated river water and three species of fish: climbing perch (Anabas testudineus), spotted snakehead (Channa punctata), and Black tilapia (Oreochromis mossambicus) caught from the river.
This working paper is part of a review of aquaculture technologies and gender in Bangladesh in the period 1990 to 2014. It assesses how gender has been integrated within past aquaculture technology interventions, before exploring the gender dimensions associated with current approaches to transferring knowledge about homestead aquaculture technology. It draws out existing knowledge, identifies research gaps, and selects practices to build upon--as well as practices to move away from.
A habitat is the environment where species such as fish live, feed and breed. A small, specialized area of a habitat (a microhabitat) can be created and managed as a way to attract and encourage a species to use the environment. These microhabitats help maintain the biodiversity of ecosystems, which in turn support livelihood activities and the production of food. This brief describes the use of fish ring microhabitat developed by WorldFish for use in rice fields in Bangladesh and its benefit.
The USAID-funded Cereal Systems Initiative for South Asia in Bangladesh (CSISA-BD) project is a five-year initiative implemented through a collaboration between three CGIAR member centers, the International Rice Research Institute (IRRI), International Maize and Wheat Improvement Center (CIMMYT) and WorldFish. The project aims to increase household income, food security and livelihoods in impoverished and agriculturally-dependent regions of Bangladesh.
ACIAR, in collaboration with the Secretariat of the Pacific Community (SPC), organised a symposium on tropical sea cucumber aquaculture at SPC Headquarters in Noumea, New Caledonia, in February 2011. Although the principal focus was on ACIAR work, particularly in the Asia–Pacific region, researchers from other parts of the world were invited to provide additional expertise. The symposium identified knowledge gaps and highlighted researchable topics for future developments in sea cucumber aquaculture.
Following two decades of work on aquaculture technologies for smallholder farmers, WorldFish is leading the aquaculture component of the Agriculture and Nutrition Extension Project (ANEP), targeting poor farmers in Bangladesh and Nepal.The main goal of ANEP aquaculture component was to increase fish production, household nutrition, incomes and alternative employment opportunities for smallholders by facilitating the adoption of productive and environmentally sustainable agricultural technologies.
Increasing agreement on the relevance of gender and social equalities to agricultural development outcomes has not come with the same consensus within the development community regarding ways to intervene in the sector to foster equality. The guiding principles of agriculture research for development (AR4D) and its focus on capacity development can contribute to this debate and to advancing gender integration in the sector if the "social threads" within its principles are developed more thoroughly.
