Participatory action research on climate risk management, Bangladesh

The rural populations of southern Bangladesh are some of the most vulnerable communities in the world to the future impacts of climate change. They are particularly at risk from floods, waterlogged soils, and increasing salinity of both land and water. The objective of this project was to analyze the vulnerability of people in four villages that are experiencing different levels of soil salinity.

Integrated farming in Zimbabwe

Integration of aquaculture with agricul¬ture (integrated farming) provides balanced food production, increases farmers' income, recycles nutrients, protects the environment and optimizes food production where resources are limited. Zimbabwe is a land-locked country with abundant resources in the form of dams, lakes, streams, rivers and groundwater. The rationale for development of integrated farming in Zimbabwe is given.

Institutional arrangements in seasonal floodplain management under community-based aquaculture in Bangladesh

Seasonal floodplains under private and public ownership in the Indo-Ganges river basin provide food and income for millions of people in Bangladesh. Floodplain ownership regimes are diverse, covering the whole spectrum from public to private ownership. The paper compares community-based fish culture projects in these floodplains and analyzes the institutional arrangements of three different Floodplain Management Committees (FMC).

Increasing water productivity in agriculture

Increasing water productivity is an important element in improved water management for sustainable agriculture, food security and healthy ecosystem functioning. Water productivity is defined as the amount of agricultural output per unit of water depleted, and can be assessed for crops, trees, livestock and fish. This chapter reviews challenges in and opportunities for improving water productivity in socially equitable and sustainable ways by thinking beyond technologies, and fostering enabling institutions and policies.

Improved management, increased culture and consumption of small fish species can improve diets of the rural poor

In many low-income countries with water resources, small fish species are important for the livelihoods, nutrition and income of the rural poor. The small size of fish favours frequent consumption by and nutrition of the rural poor, as these fish are captured, sold and bought in small quantities; used both raw and processed in traditional dishes; and are nutrient-rich. All small fish species are a rich source of animal protein, and – as they are eaten whole – have a very high content of bioavailable calcium. Some are rich in vitamin A, iron, zinc and essential fats.

Impacts of climate change and variability on fish value chains in Uganda

Fish are a significant source of income and food security in Uganda, highly vulnerable to climate and non-climate related drivers of change. This study examines the vulnerability of the fish sector in Uganda as it relates to the predicted impacts from climate change and variability, using the concept of the value chain. The specific purpose of the study was to identify current and potential impact pathways of climate change and corresponding adaptation strategies in fish value chains.

The forgotten service: food as an ecosystem service from estuarine and coastal zones

In this chapter, we review in detail the existing body of literature and knowledge related to the provision of food in estuaries and coastal zones. Both aquatic and terrestrial commodities are considered. The chapter highlights not only the importance of the terrestrial zone in overall food provision but also the substantial contribution of aquatic coastal resources. The various problems that the coastal zone faces in sustaining this important provisioning service in the face of increasing pressure and demands from other sectors are highlighted.

Fisheries and aquaculture policy for education, research and extension in Nepal

Fisheries and aquaculture policy for education, research and extension is derivatives of the main national agriculture policy. Fisheries and aquaculture is a dynamic sub-sector of agriculture sector having high growth potential but with low organizational stature in Nepal. The modern aquaculture along with fisheries practices contributes nearly 1% of Gross Domestic Production (GDP) and 2.68% of Agriculture Gross Domestic Production (AGDP).

Fish biodiversity research in the Mekong Basin

The Mekong River is one of the great rivers of the world and is characterized by high fish biodiversity. A number of organizations are working at observing and protecting aquatic biodiversity in this hotspot of global importance. Among them are international organizations such as the WWF, Wetlands International, the International Union for Conservation of Nature (IUCN), and the United Nation Environment Program (UNEP) but also regional institutions and national line agencies or nongovernmental organizations (NGOs).

Effects of stocking density on production and economics of all-male tilapia (Oreochromis niloticus) culture in a rain fed rice-fish ecosystem

Effects of stocking density on the growth, production, and economics of all-male tilapia (Oreochromis niloticus) were investigated in a rain-fed rice-fish ecosystem for a period of 120 days. Fish were stocked at the rate of 4000, 5000, and 6000 ha-1 in treatments T1, T2, and T3, respectively. Water quality was suitable for fish culture. Significantly higher growth was observed in T1 as compared to other treatments. SGR ranged from 1.26 to 1.51. Survival varied between 79% and 88% with treatment T1 producing the highest survival.
