Subsistent and commercial farming
Subsistent farming - where farmers only produce enough food for themselves and their families to eat. Usually farmers use slash and burn techniques to clears areas to grow their crops. Increase in population lead to increase in subsistent farming.
Commercial farming - agriculture with the direct intention of making profit from the produce. Palm oil plantations have been made by mass deforestation to clear an area. This is due to the 10 year tax incentives for producing palm oil.

Development opportunities in the thar desert
Mining - the thar desert has valuable reserves of minerals such as Feldspar, phosphorite, gypsum and kaolin. These minerals are used to produce a range of things from cement to fertilisers and are therefore valuable. Limestone and marble are also quarried in the area. Limestone is used for building and producing cement and marble is used in construction.
Energy generation - Energy is produced in the thar desert using solar panels. This energy is used to clean water supplies contaminated with salt. Wind energy is also used to generate electricity. Jaisalmer wind farm has 75 wind turbines and has the capacity to produce 60 megawatts of electricity.
Farming - irrigation in the Thar desert has made commercial farming viable. Producing crops such as wheat and cotton has created many jobs and generated income for the local communities
Tourism - the Thar desert national park attracts many people who want to see the 120 species it has to offer. Tourists explore the desert with local tour guides on camels. Tourism creates many jobs for local people.
Challenges of development in the Thar desert
Extreme temperatures - temperatures in the Thar desert can exceed 50 degrees Celsius in summer months. It is hard for people to farm, work in mines or as tourist guides in these months because it is too hot.
Water supply - the supply of water in the Thar desert is precious and limited. With only 120-240mm of rain falling per year in the desert, water must be used sensibly and sustainably. Without water development of mining, farming and tourism would not be possible. Some areas experience over-irrigation which has caused water logging in the ground. The water evaporated and leaves a layer of salt on the surface making it very difficult to grow crops and make an income.
Inaccessibility - the desert covers an area of 200,000 square kilometres. Most of the desert is inaccessible due to the extreme environmental conditions and poor infrastructure. Beyond the city of Jaisalmer, development is limited. Inaccessibility to many parts of the desert has led to great differences between the rich and the poor.
