Environment
Overuse and poor irrigation practices have led to increased salt content in the soil, reducing the productivity of the land. Irrigation salinity is caused by water soaking through the soil level adding to the ground water below. This causes the water table to rise, bringing dissolved salts to the surface. As the irrigated area dries, the salt remains. At Wakool in the Riverina region of New South Wales, irrigation salinity is mitigated through a salt interception scheme that pumps saline ground water into evaporation basins, protecting approximately 50,000 hectares of farmland in the area from high water tables and salinity. The subsequent salt has various uses including as an animal feed supplement. The program has returned to production over 2,000 hectares of previously barren farmland and encouraged the regeneration of native eucalypts.

Famous quotes containing the word environment:
“Autonomy means women defining themselves and the values by which they will live, and beginning to think of institutional arrangements which will order their environment in line with their needs.... Autonomy means moving out from a world in which one is born to marginality, to a past without meaning, and a future determined by others—into a world in which one acts and chooses, aware of a meaningful past and free to shape one’s future.”
—Gerda Lerner (b. 1920)
“White males are the most responsible for the destruction of human life and environment on the planet today.”
—Robin Morgan (b. 1941)
“We learn through experience and experiencing, and no one teaches anyone anything. This is as true for the infant moving from kicking to crawling to walking as it is for the scientist with his equations. If the environment permits it, anyone can learn whatever he chooses to learn; and if the individual permits it, the environment will teach him everything it has to teach.”
—Viola Spolin (b. 1911)
