Population pressure- the Thar Desert is the most densely populated desert in the world, with a population density of 83 people per km2, and the population is increasing
Water management- excessive irrigation is some places has led to water logging. Slats poisonous to plants have been deposited on the ground.
Soil erosion- over cultivation and overgrazing have led to soil erosion by wind and rain. This is called salinisation.
Fuel- the main source of fuel, firewood, is running out. Maure is being used instead of being used to improve the quality of soil.
Tourism- popular because of beautiful landscapes, wealthy people go there. Local people benefit by doing guided tours on camels. The environment will suffer if tourism becomes overdeveloped.
