This book by AgSri , attempts to explain the origin, principles and practices of System of Rice Intensification (SRI), a technology that aims to save water and also enhance the rice yield.

This paper from the gatekeeper series of the International Institute for Environment and Development (IIED) describes the potential of an innovative rice cultivation practice-the system of rice intensification (SRI)—for allowing Indian rice farmers to not only enhance rice production and their net incomes, but also to solve the water crisis.

This  brings together the results of formal research on SRI in a number of countries (Part I) and also reports on initiatives by government agencies, NGOs, universities, or the private sector, bringing knowledge of SRI to farmers in a wide range of agroecological circumstances (Part II). It has six articles and nine technical reports from Afghanistan, China, the Gambia, Kenya, India, Indonesia, Iraq, Mali,  Pakistan, Panama, and Thailand as well as several review articles.

The System of Rice Intensification (SRI), developed in Madagascar almost 30 years ago, modifies certain practices for managing plants, soil, water, and nutrients with the effect of raising the productivity of the land, labor, and capital devoted to rice production. Certain production inputs are reduced—seeds, inorganic fertilizer, water, and fuel where water is pumped—with increased yield as a result.
