As we traveled westwards from Jodhpur into the deep desert, we raced past tiny villages. A day later, as we stood in a little oasis in the desert and saw a herd of sheep come in to graze and drink water, I started to wonder about the livelihood of people who live here. The desert covers about 60% of Rajasthan. The population density of about 80 persons per square kilometer is about a fifth of the rest of Rajasthan. Still, the desert holds more than 15 million people. How do they live, what do they do?
Herding is a major traditional livelihood. Apart from sheep we saw goats, cows and donkeys. The photo which you see above was taken near one of the largest oases in the western desert. Ground water is scarce in the desert; we hardly saw any wells. Because of this, traditional herders were nomadic, driving their livestock from one oasis to another. I don’t know whether this lifestyle is still possible today. I suspect that the slightly improved supply of water, from the Indira Gandhi Canal, has contributed to the settling of nomads. Another factor in the settling of nomads is the plentiful electricity from wind generators: you need to have a settled address in order to tap into the electric grid
There was evidence of subsistence farming, as in the photo above. I had to keep my nose and mouth constantly covered against blowing dust, so I suspect that there is little soil here. Farming cannot be a paying proposition. The article on the Thar desert in Wikipedia claims that a third of crops fail. This figure is not referenced, and may be inaccurate. New crops are constantly tried out, and it was clear that pearl millet (bajra) is a success. We had wonderful bajra roti all through our trip. The Family pointed out that the bajra is better than what we get in Mumbai. On the other hand, it is also clear that there is a constant battle to contain the desert.
One possible future for India due to global warming is widespread desertification of the country. This is not inevitable, because good policies and innovation in large-scale rain and ground water management could lead to a different future. The Thar desert is a laboratory for how we could try to manage this kind of disastrous future.
