Abstract
Western Rajasthan accounts for 61% of the total hot arid zone in India (31.7 m ha). The rest of the arid area is spread over Gujarat (20%), Punjab and Haryana (9%), as well as small parts of Andhra Pradesh and Karnataka (10%). The arid region receives <450 mm annual rainfall with 40-80% coefficient of variation. With evapotranspiration (ET) four to five-fold higher than rainfall, aridity, deficit water balance, and scarcity of water for drinking and other purposes are often severe. Natural resources such as water, land and vegetation are very fragile and partly non-resilient, and hence the area is prone to irreversible land degradation and desertification under excessive pressure from human and livestock populations. Arable cropping alone is not a dependable proposition in these drylands. Animal wealth provides sustainable support to livelihoods, but the sector is not yet well organized. Only one crop can be grown during a good rainfall year, and on average, a year of good harvest is normal during a cycle of five years, while two are expected to yield moderate crops and at least two failures are usual. The arid region offers limited scope for water harvesting and recycling, particularly at a watershed scale. There is better scope for integrated land resource development on the basis of village clusters, index catchments and dune-interdune complex.
