Descripción:	The concept of runoff inducement for agricultural purposes is discussed in detail. its implications to the Northeast Brazilian conditions and necessity for additional research is explained. An exaustive review of the research at various places in the world is included. The latest work being carried out at the Centro Nacional de Pesquisa do Tropico Semi-Arido (CPATSA/Embrapa) (Center of Agricultural Research for Semi-Arid Tropics) is explained in detail. This work included development of eight small watersheds varying in size from 1.0 ha. to 2.7 ha. for hydrologic evaluation of various simple low cost runoff inducement methods under natural "caating" conditions on shallow to medium deep Latossols. The various methods of runoff inducement include combinations of intensified grassed waterways, strip clearing of caatinga, narrow based channel terraces (or graded bunds) for soil conservation, salt treatment on cleared strips and complete clearing of caating with grass cover.
