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.

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.

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.

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.

Functional aquatic ecosystems, inland fisheries and the Millennium Development Goals

Freshwater allocation in an environment of increasing demand and declining quality and availability is a major societal challenge. While biodiversity and the needs of local communities are often in congruence, the over-riding necessity of meeting national demands for power, food and, increasingly, mitigation of the hydrological effects of climate change, often supersedes these.

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.

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.

Enhancing the Productivity of Small Waterbodies

Most small waterbodies were built for irrigation and/or drinking water storage for humans and livestock, but have also been shown to play an important role in watershed management. Apart from natural lakes, small waterbodies are generally of two types: 1) reservoirs created by damming a river and, 2) ponds built on watersheds to collect and store surface runoff. There are millions of small waterbodies scattered throughout the world, most of which are poorly or not at all managed for fish production.

The Bayfish project: the creation of a suite of tools to show how the production of aquatic resources in tropical inland systems

The BayFish models are decision-support tools that show, and predict, the impact of land use and water management options on water-dependant food production. They allow users to see all the dimensions that need to be considered for a given modification of the system, and to allow down-the line the impacts of any suggested changes.

Applying Resource Management Domain (RMD) concept to land and water use and management in the coastal zone: case study of Bac Lieu province, Vietnam

Because of changing hydrological conditions due to infrastructure development to prevent salinity intrusion into the coastal zone, local authorities in Bac Lieu Province, Vietnam, faced complex natural resource management issues concerning managing saline and freshwater resources to support diverse production activities in the coastal zone while farmers had to adjust their production strategies.
