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.
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.
With rapidly increasing investment in water control infrastructure (WCI) and a recently ratified agriculture development strategy that promotes integrated farming of high-value products such as fish, agricultural production, already fundamental to Myanmar’s economy, will be central to driving the countries’ socioeconomic transformation. Water planners and managers have a unique opportunity to design and manage WCI to incorporate fish and, in so doing, reduce conflicts and optimise the benefits to both people and the ecosystem services upon which they depend.
Dams and the reservoirs they create are increasingly ubiquitous in landscapes throughout the world. They have a major impact on fisheries, presenting both opportunities and constraints.
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.
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.
