The impacts of integrated homestead pond-dike systems in relation to production, consumption and seasonality in central north Bangladesh

The roles of homestead ponds and surrounding dike production of vegetables on farms in peri-urban and rural communities in central north Bangladesh were assessed. The study supports the view that small homestead ponds can contribute to the wider food supply, and that such “quasi-peasant” forms of aquaculture contribute to reduced poverty and enhanced dietary diversity and food security in the broader population.

Higher fish but lower micronutrient intakes: Temporal changes in fish consumption from capture fisheries and aquaculture in Bangladesh

This study shows people in Bangladesh are now eating 30% more fish than they did 20 years ago, but they are getting a smaller amount of important nutrients from it. The results challenge the conventional narrative that increases in food supply lead to improvements in diet and nutrition. As aquaculture becomes an increasingly important food source, it must embrace a nutrition-sensitive approach, moving beyond maximising productivity to also consider nutritional quality.

Heavy metal contamination in surface water and sediment of the Meghna River, Bangladesh

The present study was designed to evaluate the temporal variation of ten metals (Al, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, Zn) in the surface water and sediments of the Meghna River, Bangladesh during rainy, winter and pre-monsoon seasons by generating some baseline information on metal pollution in these proposed areas.

Gender relations and improved technologies in small household ponds in Bangladesh: Rolling out novel learning approaches

Gender-transformative engagement in the management of household ponds in Bangladesh for improved fish production relies on working with the complexities of gender relations in combination with a readiness by formally-trained scientists to allow women and men farmers to "follow the technology". Innovative methodologies for technology development and dissemination need to focus on promoting farmer adaptive capacity and enabling farmers to take charge of their own learning. This is not a gender-neutral process.

Factors determining the productivity of mola carplet (Amblypharyngodon mola, Hamilton, 1822) in carp polyculture systems in Barisal district of Bangladesh

Production of the mola carplet (Amblypharyngodon mola), a small vitamin A rich fish, has the potential to reduce human malnutrition in Bangladesh. However, although efforts have been made to promote mola culture, the factors affecting its production are poorly understood. Therefore, this study was undertaken to identify factors contributing to mola productivity in polyculture systems. The study indicates that application of appropriate inputs could be considered to maximize production of mola in future projects attempting to promote its culture.

Estimates of average energy requirements in Bangladesh: Adult Male Equivalent values for use in analyzing household consumption and expenditure surveys

This dataset contains Adult Male Equivalent (AME) values for use in Bangladesh. These were constructed using prescriptive nutritional constructs adapted to the actual growth and weight pattern seen in Bangladesh. This dataset provides a common base to facilitate for future work with household consumption and expenditure data in Bangladesh while updating the energy requirements for infants and young children for the WHO 2006 growth standards and 2007 growth reference curves.

Empirical yield-effort models for Bangladesh inland fisheries

This paper aims to support community-based fisheries management (CBFM) of inland fisheries resources in Bangladesh. An investigation into the impact of the nationwide CBFM Project and four alternative yield-effort models were fitted to the catch (yield) and effort data. The study comprised community managed fisheries (sites) located in five different inland water habitat types in Bangladesh for the period 1997-2005.

Drivers of mangrove ecosystem service change in the Sundarbans of Bangladesh

Mangroves are now well known to provide a range of ecosystem services that benefit local populations, though such ecosystem services are at risk from mangrove deforestation and degradation across much of the tropics. This study aimed to identify the natural and anthropogenic drivers of change that affect ecosystem services of the Sundarbans mangrove forest.

Community-based resource management approaches adopted in the three tributaries of River Surma, North-East Bangladesh

Freshwater fishery resources are declining in Bangladesh due to over exploitation, anthropogenic causes and inadequate management. To improve sustainability of these resources, a community-based resource management initiative was implemented by Bangladesh's Local Government and Engineering Department. Working in partnership with community-based resource management the communities implemented a variety of management interventions. The purpose of this study is to assess the impact of community-based management on fisheries production and biodiversity.

Carp-mola productivity and fish consumption in small-scale homestead aquaculture in Bangladesh

Small indigenous species (SIS) of fish such as the mola carplet (Amblypharyngodon mola) are rich in nutrients, often containing high levels of zinc, iron, and vitamin A. Despite scientific and government efforts, culture of SIS for improved nutrition is not yet widespread. This paper investigates the contribution of the mola carplet, commonly referred to in Bangladesh as ‘‘mola’’ to household fish consumption, and the factors influencing productivity and income from carp–mola polyculture in southwest Bangladesh.
