The Department of Water Western Australia website provides information about catchment management and water quality issues such as salinisation, loss of vegetation, nutrient enrichment, erosion and sedimentation, contamination and sustainable use.
Fisheries Western Australia has information about recreational fishing, aquaculture and pearling, fish and habitat protection and commercial fishing. It also has education links.
For billions of people, seafood provides a significant source of protein and nutrition, but over half the seafood we eat isn’t caught in the wild, it’s grown through aquaculture. Farmed seafood is one of the fastest-growing food industries, but the farming methods echo the problems we’ve seen in industrial agriculture. Is there a way to sustainably farm the ocean? Ayana Johnson and Megan Davis investigate.
Fisheries research at the Institute for Marine and Antarctic Studies supports the long-term, sustainable harvest of wild marine resources. It has been estimated that aquaculture could provide 70% more food to feed an additional 2.3 billion people by 2050.
The Australian Agriculture and Water Resources homepage has links to rural industries, research, forestry, quarantine, agriculture, environment and greenhouse, and fisheries.
'The Convention on Wetlands, signed in Ramsar, Iran, in 1971, is an intergovernmental treaty which provides the framework for national action and international cooperation for the conservation and wise use of wetlands and their resources.' This website provides further information, key documents, World Wetlands Day, further links, images etc.
This report covers the range of wetlands as defined by the Ramsar Convention on Wetlands. These include inland wetlands (such as swamps, marshes, lakes, rivers, peat lands, and underground water habitats); coastal and near-shore marine wetlands (such as coral reefs, mangroves, sea grass beds, and estuaries); and human-made wetlands (such as rice fields (paddies), dams, reservoirs, and fish ponds). Environment change and management: human-induced environmental changes that challenge sustainability.
Eutrophication, the gradual increase in the concentration of phosphorus, nitrogen, and other plant nutrients in an aging aquatic ecosystem such as a lake. The productivity or fertility of such an ecosystem naturally increases as the amount of organic material that can be broken down into nutrients increases.
