Desertification Is Devouring India. But There's Hope in the Dunes

The people of a small village on the edge of the Thar Desert have managed for decades to resist "desertification" -- degradation of arid land to the point that it is uninhabitable -- by storing monsoon waters for use later. The storage device, rectangular plots of land called chaukas, have worked well enough to be copied by dozens of other villages in the area. It is uncertain if this approach can reverse the loss of land, but it is at least holding off the rapid pace of desertification, which risks mass displacements of people as hundreds of millions of acreage is lost.
