Water and housing in desert:

        The rains play a vital role in the life of all parts of Thar as the water deposits in tobas (small ponds) are used for drinking, washing and other purposes. These tobas are the only source of water for animals and human in most of the desert area. Just for this reason, major portion of the  population lives like gypsies. When a toba comes to dry, they move to the next destination around the water-filled toba. The human settlements are mostly found near the Karon-Jhar hills where two seasonal streams flow but not in all the seasons. The underground water is rarely found in Thar desert. If luckily found, after digging a very deep well, it comes out quite sour and putrid. Simply undrinkable. Sometimes fortune do knock the doors of the Thar inhabitants, when sweet water comes out of a very deeply dug well. Then the housing units start increasing around that well. Digging the well is not so easy a number of times,

 it claims the lives of the well-diggers. According to 1980 housing census, there were 241,326 housing units of one or two very small rooms. The degree of crowding was six persons per housing unit and three persons per room.

For most of the housing units (approximately 76 per cent), the main construction material of outer walls is unbaked bricks whereas wood is used in 10 per cent and baked bricks or stones with mud bonding in 8 per cent housing units. A large number of families still live in jhugis (one room housing units formed with straws and thin wood-sticks). The wind storm proves these jhugis unsustainable all the times. But the poverty leaves no other option to these jhugiwalas (people living in jhugis).
