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.

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.

Pen fish culture in reservoirs: an alternative to land based nurseries

An experiment to rear carp seed was conducted in Tamil Nadu, India during October 2001 to April 2002 as a part of an ambitious programme aimed at standardization of pen fish rearing technology for production of stocking material of desired size at a lower cost. The experiment used six pens erected using locally available materials in the exposed marginal area of an existing reservoir.

Willingness to pay for conserving Layawan watershed for domestic water supply in Oroquieta City, Philippines

The sustainability of domestic water supply from the Layawan Watershed in Oroquieta City critically depends on past and present conservation activities and the availability of funds from stakeholders such as households, communities, non-government organizations, private entities and government agencies. This study determined the willingness to pay (WTP) particularly of households in Oroquieta City to finance conservation projects in Layawan Watershed to ensure the sustainability of domestic water supply.

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.

Tonle Sap scoping report

The scoping mission team was composed of 14 people representing research institutions (RUPP), government (FiA, IFReDI), NGOs (ANKO, ADIC) and CGIAR institutions (WorldFish and Bioversity). The scoping trip was carried out over a 7-day period from April 28 to May 4 within eight (8) communities in Kampong Thom, Siem Reap, Battambang, Pursat and Kampong Chhnang. In addition, panel discussions were held with local government, fishery, agriculture and water management institutions, NGOs, the private sector and communities, and were convened in Siem Reap, Battambang and Pursat.

Solomon Islands Aquatic Agricultural Systems program design document

WorldFish is leading the CGIAR Research Program on Aquatic Agricultural Systems together with two other CGIAR Centers; the International Water Management Institute (IWMI) and Bioversity. In 2012 and 2013 the AAS Program rolled out in Solomon Islands, Zambia, Bangladesh, Cambodia and the Philippines. Aquatic Agricultural Systems are places where farming and fishing in freshwater and/or coastal ecosystems contribute significantly to household income and food security. The program goal is to improve the well-being of AAS-dependent people.

Increasing water productivity in agriculture

Water productivity is defined as the amount of agricultural output per unit of water depleted and can be applied to crops, trees livestock and fish. This chapter reviews challenges and opportunities to improve water productivity in socially equitable ways and in different agro-climatic systems. In areas with ample water supply, developing new and making better use of existing water resources are options, whereas in areas with physical water scarcity, better water harvesting and storage is warranted.
