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:
“Could it not be that just at the moment masculinity has brought us to the brink of nuclear destruction or ecological suicide, women are beginning to rise in response to the Mother’s call to save her planet and create instead the next stage of evolution? Can our revolution mean anything else than the reversion of social and economic control to Her representatives among Womankind, and the resumption of Her worship on the face of the Earth? Do we dare demand less?”
—Jane Alpert (b. 1947)
“The child thinks of growing old as an almost obscene calamity, which for some mysterious reason will never happen to itself. All who have passed the age of thirty are joyless grotesques, endlessly fussing about things of no importance and staying alive without, so far as the child can see, having anything to live for. Only child life is real life.”
—George Orwell (1903–1950)
