Land and Water Managment

Groundwater

Facts: - About 10% of Australia's natural environments has been assessed as highly stressed. - Grape growers are expected to be the hardest hit by the lack of irrigation for their crops.- Rapid growth of algal blooms as a result of low water inflows.

Water management: Murray-Darling river system.The Murray-Darling River is one of the largest river systems in the world but by far carries the smallest volume of water for a major river. Therefore water management is a big concern. If the water is not managed properly then we risk it failng to support healthy environements and the animals that live there, industries that rely on water use and communities that live along the river. Scarcity, salinity, damming and pollution are the key areas of concern regarding water mismanagement.

Biodiversity

Catchment

Land and water management is enviromental altervations that benifit us but not the animals that live there. Some examples are changing the nature of the Australian landscape for farmlands. The distruburbing of natural grasslands. The altering of natural rivers systems for irrigation. These three changes have not only affected our enviorment but the finaces in maintaning water pollution and our natural land.

Promoting sustainabilty, social justice and equality.

Murray River closed over in 1981 due to land and water mismanagement.

Salinity

Irrigation

Erosion

Inflows

Land management: foreste are being cut down for farmlands.We are still clearing more native vegetation then is being planted or regenerating naturally. This ongoing net loss continues to threaten Australia's environement.This clearing increases erosion and sedimintation of waterways and water quality. Rates of land cleared are highest in Queensland and NSW.
