Rajasthan, with geographical area of 342 lac hectare, is the largest State of the country, out of which 101 lac hectare is wasteland. The Aravali range extends from South-West to North-East and divides the State in two parts. Western side of the State consists of Thar desert, which is almost 60% area of the State.
Unfortunately Rajasthan is the driest state in the country and is water scarce (having per capita water availability below 1000 m3/year) since 1991. With prevailing high growth rate of population the per capita water availability is going to further reduce to alarmingly low levels implying that the challenges for water sector are much more and severe in the State.
