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:
“People between twenty and forty are not sympathetic. The child has the capacity to do but it can’t know. It only knows when it is no longer able to do—after forty. Between twenty and forty the will of the child to do gets stronger, more dangerous, but it has not begun to learn to know yet. Since his capacity to do is forced into channels of evil through environment and pressures, man is strong before he is moral. The world’s anguish is caused by people between twenty and forty.”
—William Faulkner (1897–1962)
“Maturity involves being honest and true to oneself, making decisions based on a conscious internal process, assuming responsibility for one’s decisions, having healthy relationships with others and developing one’s own true gifts.

—Mary Pipher (20th century)
