Impacts of community-based fish culture in seasonal floodplains on income, food security and employment in Bangladesh

This paper examines the impact of community based fish culture in seasonal floodplains on fish production, consumption, income, and food security of the participating households in Bangladesh. An analysis was performed using a randomly selected 46 % of the households from the three project and control floodplains; data were collected using longitudinal surveys on a seasonally, quarterly and monthly basis for the years 2007, 2008 and 2009.

Transboundary research in fisheries

Spatial boundaries have become an indispensable part of regimes and tools for regulating fisheries, with examples including marine protected areas, regional fisheries management organizations and Exclusive Economic Zones. Yet, it is also widely acknowledged that boundaries are a social construct, which may be resisted by both fishers and fish ecology. The ensuing spatial and institutional mismatches have been shown to frustrate management efforts, exacerbating issues of non-compliance and ultimately leading to conflicts and overfishing.

Gender inequalities in access to and benefits derived from the natural fishery in the Barotse Floodplain, Zambia, Southern Africa

People living in and around the Barotse Floodplain are some of the poorest in Zambia due to many factors restricting their abilities to engage in activities to secure food and income. Women, and in particular resident women, are especially constrained given certain gender norms and power relations that hamper them from accessing and adequately benefiting from the natural fishery. Resident women typically rely on other, less remunerative means to secure their livelihoods.

Coping with resettlement: A livelihood adaptation analysis in the Mekong River basin

A major driver of change in the Mekong River basin relates to hydropower development and the consequent changes in landscape and natural resource access regime that it induces. In this paper, we examine how the livelihoods of resettlers evolve following resettlement, and examine the determinants of that process. The study takes place in the context of the Theun Hinboun Expansion Project in Lao PDR. Based on longitudinal household surveys conducted before resettlement as well as 1, 2, and 3 years after resettlement, we identify the process of livelihood adaptation in resettled communities.

Aquaculture big numbers

This research project seeks to: provide baseline information on the present status of the aquaculture sector from a human development perspective; identify the types and numbers of people employed by the sector; and explore the role of aquaculture in providing social and economic services at a global level, with a particular emphasis on small-scale stakeholders. The research findings presented here are based on a global synthesis of information from various sources and 9 country case studies in Asia, Africa and Latin America.

Non-farmed fish contribute to greater micronutrient intakes than farmed fish: results from an intra-household survey in rural Bangladesh

Fish is the most important animal-source food (ASF) in Bangladesh, produced from capture fisheries (non-farmed) and aquaculture (farmed) sub-sectors. Large differences in micronutrient content of fish species from these sub-sectors exist. The aims of the present paper are to describe the importance of fish in the diets of vulnerable groups in comparison to other ASF, and the contribution of species from non-farmed and farmed sources to nutrient intakes.

Explaining climate variability vis-a-vis spatio-temporal interactions in Bangladeshi Exclusive Economic Zone (BEEZ)

We present an application of time series remote sensing data and climatological information for improved understanding of complexity in the Bangladeshi Exclusive Economic Zone (BEEZ). Three seasonal slots from the annual climate calendar of the temporal slice 1998 to 2009 are selected: December-February [DJF], March-May [MAM] and September-November [SON]) to assess the relationship between marine fish productivity and climate induced variations in a pelagic system.

Genetic improvement of farmed tilapias: Response to five generations of selection for increased body weight at harvest in Oreochromis niloticus and the further impact of the project

Selection for increased body weight at harvest in Nile tilapia (Oreochromis niloticus) was carried out for five generations from 1991 to 1996, as a part of the project Genetic Improvement of Farmed Tilapias (GIFT). The base population for selection was composed of a mixture of various three- and four-way cross individuals descending from four wild African strains and four farmed Asian strains.

Can community-based adaptation increase resilience

A central claim of community-based adaptation (CBA) is that it increases resilience. Yet, the concept of resilience is treated inconsistently in CBA, obscuring discussion of the limitations and benefits of resilience thinking and undermining evaluation of resilience outcomes in target communities. This paper examines different participatory assessment activities carried out as part of CBA case studies in Timor-Leste and Solomon Islands.

A Manual for improving fish production in Northern Zambia through integrated farming systems

This manual was written as part of the Integrated Research in Development for Improved Livelihoods Programme in Northern Province, Zambia (IRDLP) and is primarily intended for extension agents to use with smallholder farmers engaged in semi-intensive fish farming in Northern Zambia. The IRDLP is an Irish Aid-funded project implemented by WorldFish, Harvest Plus and the Center for International Forestry Research (CIFOR).
