Rajasthan is neatly divided in two by the Aravalli hills, to whose east the Thar extends to the Indus in Pakistan. This 'Great Indian' desert has long been the most densely populated arid area of the world, a distinction that represents a fundamentally sustainable approach towards land use and, in recent years, an ecological disaster as the population has exploded over the region's carrying capacity.
Until the advent of large-scale irrigation, the internal combustion engine, and modern health care the residents of the Thar desert had worked out a very stable economic system whose roles and rules were prescribed by a very strict social code. Nomadic castes (such as the oft-mentioned raikas) herded camels, cattle, goats, or sheep across carefully maintained rangelands whose use was carefully regulated by religious authorities. Small farmers relied on rainfall (averaging about 5-10 inches a year) for their small harvest of millet, pulses, and sorghum; the large variation in yield meant that land consolidation was by and large impossible and small villages remained economically independent. In the cities, the ruling and merchant castes found wealth in the taxation of trade, regulating both overland caravans and the access of the small farmers to larger markets.
As this system anticipated aridity, it was much more resistant to temporary environmental change than, say, a riparian culture completely unprepared for the failure of a flood. The entire success of the system, however, depended on the marginal prosperity of farmers, who in turn relied upon scant and erratic rain. The devastation wrought by drought in Bikaner is legendary in city lore.
