Problem
Inappropriate irrigation schemes
Other Names:
Destruction of arid ecosystems by irrigationInappropriate irrigated agriculture
Nature:
Irrigation is as much a problem as a solution to improved agriculture. The majority of the world's available freshwater goes to agriculture and inefficient irrigation systems waste a considerable amount of it. Waterlogging and increased salinity and/or alkalinity can defeat the very purpose of the irrigation scheme. In almost every irrigation zone, significant species shifts in soil fauna and plants can be found. Enlarged insect populations spread diseases such as malaria.
