Ecological Importance
Since the economy of the region is based on agriculture, subsistence depends on snowmelt and rainfall in the high mountains to sustain the health of the Sistan Basin and its wetlands. This source of water severely fluctuates over time and therefore has resulted in fundamental problems of survival for human settlements in the area. A severe drought began at the turn of twenty-first century and as of 2005 has lasted six years with extreme consequences for the populations.
The region's economic survival is dependent on the wetland's products. For example, beds of reeds provide livestock food, cooking and heating fuel, and the raw materials for structures and handicrafts. Water availability affects the income derived from fishing and hunting, an important source of income. The result of the drought has been the collapse of the local economy as well as destruction of the wetland's ecological system, causing damage to the agriculture in the delta based on the Helmand River's irrigation.

Famous quotes containing the words ecological and/or importance:
“It seems to me that there must be an ecological limit to the number of paper pushers the earth can sustain, and that human civilization will collapse when the number of, say, tax lawyers exceeds the world’s total population of farmers, weavers, fisherpersons, and pediatric nurses.”
—Barbara Ehrenreich (b. 1941)
“Society is the stage on which manners are shown; novels are the literature. Novels are the journal or record of manners; and the new importance of these books derives from the fact, that the novelist begins to penetrate the surface, and treat this part of life more worthily.”
—Ralph Waldo Emerson (1803–1882)
