Water quality research or water quality checking: proposed guidelines

A simple plan is outlined to assist in the design of water quality research and monitoring programmes at aquacultureresearch stations. Before monitoring any programme, a decision on the goals of the aquaculture research to be performed is crucial to planning; the plan follows two major pathways--fish yield parameters-water quality checkingprogramme; and, water quality parameters/water quality research programme.

Redistribution of water use and benefits among hydropower affected communities in Lao PDR

In this paper, we assess how resettlement and changes in water access have altered livelihoods of local communities upstream of the Theun Hinboun Expansion Project in Lao PDR. Based on household surveys conducted both before and after resettlement, we estimate changes in water use and benefits among households of 4 resettled villages.

Multiple water use as an approach for increased basin productivity and improved adaptation: a case study from Bangladesh

This study, supported by the Challenge Program Water and Food (CPWF-Project 35), demonstrates the case of multiple-use of water through seasonal aquaculture interventions for improved rice–fish production systems in the Bangladesh floodplains. The project focused on community-based fish culture initiatives, increasingly adopted in the agro-ecological zones of the major floodplains of the Padma, Testa, and Brahmaputra basin. The productivity of water and fish is used as an indicator to explain this case.

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.

Decision support for water management for integrating aquaculture in small-scale irrigation systems: A case for the Chingale catchment in Malawi

A three-year project was funded by the BMZ/GIZ to examine the benefits of integrating aquaculture and small scale irrigation by identifying improved water allocation and management strategies under current and future climate change scenarios. An integrated modeling approach was adopted to analyze the complex issues involved in the decision processes. A water budgeting approach was used in estimating and balancing the water resources available to farming communities (the supply aspect) and the water demand for agricultural use, including crops and fish farming, within a catchment.

Concurrent rice-fish trials: comparing regular and border planting patterns

Details are given of experiments conducted at the Freshwater Aquaculture Centre at Munoz, Philippines, to investigate the effects of varying the rice planting pattern on fish yields in integrated rice field aquaculture systems.Regular planting and border planting patterns were compared and Tilapia zillii and Cyprinus carpio species were involved in the trials.

Water and fisheries

This paper highlights the importance of fisheries and aquaculture in management of the world’s water resources. It underlines the value of these resources and the critical importance of managing water quantity and quality for fisheries and aquaculture as well as for other human uses. This will require more holistic approaches to water management and the effective governance systems these require.

Evaluating the flow regulating functions of natural ecosystems in the Zambezi River Basin

By mitigating the vagaries of climate variability, agricultural water storage is widely anticipated to make a key contribution to climate change adaptation in Africa. However, if the planning of water storage is not improved, it is likely that many investments will fail to fully deliver intended benefits. This report describes the agricultural water storage continuum and some of the possible implications of climate change.
