The training manual by ICRISAT on integrated management of watersheds is meant for watershed development practitioners and provides an account of the socio-technical aspects of watershed. To begin with, the definitional aspects of watershed are spelt out -

The term “watershed” strictly refers to the divide separating one drainage basin from another. However, over the years, the use of the term watershed to signify a drainage basin or catchment area has come to stay.
Hydrologically, watershed could be defined as an area from which the runoff drains through a particular point in the drainage system.

This report prepared by ICRISAT under its Global Theme on Agroecosystems deals with the problem of gully erosion, which is common in the semi-arid region, characterized by denuded landscape and flash floods. An estimated 4 million ha land in India and 29 million ha of land in Africa are affected by severe gully erosion. Gully erosion is more difficult and expensive to control than other types of soil erosion.
