Often it is thought that imparting knowledge of 'scientific' farming methods will improve the conditions of Indian farmers. We should remember that Indian farmers have been cultivating the land for centuries, much before the advent of the Green Revolution. They have very deep and extensive traditional knowledge about the land they till and the crops they sow. Much of its knowledge, like the many traditional varieties of seeds that were developed over the centuries by farmers, is being lost as hybrid, high-yielding, and genetically modified varieties of seeds are being promoted as more productive and 'scientific (Gupta 1998; Vasavi 1999b). In view of the negative environmental and social impact of modern methods of cultivation that have been observed, a number of scientists as well as farmers' movements now suggest a return to traditional, more organic seeds and methods of cultivation. Many rural people themselves believe that hybrid varieties are less healthy than the traditional ones.

The migrant workers of rural society mainly come from drought-prone and less productive regions, and they go to work for part of the year on farms or construction sites. The term used by Jan Breman to define these workers is:

Footloose labour
