Abstract:

Excessive accumulation of salts in soils and ground water has plagued the irrigated semiarid and subhumid regions of the world for centuries. The structural measures of salinity control are effective but extremely capital intensive. A non-structural management model is presented which may help maintain a permanent irrigated agriculture at a reasonable cost. The model is based on the theory that an irrigated system consists of a number of components and that the good health of each component is vital to the overall good health of the entire system, and that ignoring even a single component could lead to disastrous consequences. A simplified limited version of the model is applied to a case study and it is concluded that the implementation of the model devised strategies could reduce the normal rate of degradation of the ground water by about 80 percent.
