Physical environment, human influences and desertification in Pushkar — Budha Pushkar lake region of Rajasthan, India

Summary

The hazard of desertification is now threatening one of the most celebrated and sacred lake regions in India, the Pushkar — Budha Pushkar region, which is situated within the Aravallis, in Rajasthan. While, on the basis of known climatic records and physical potentiality of the land, secular change of climate can be ruled out as a possible cause for the present situation, the location of the zone along the fringe of the desert, and its inherent vulnerable nature due to its terrain characteristics, are more important factors for consideration. A lack of understanding of the type of responses of the terrain to indiscriminate biotic activities, and a reluctance to take any measure to stabilize the ecosystem by the alien group of people resident in the area, have resulted in destruction of the natural vegetation, accelerated the movement of sand from the formerly well-stabilized dunes and sandy plains, and deteriorated the lake environment. However, such destructive trends could still be reversed through well planned programmes of afforestation, soil and water conservation, and people's supportive participation.
