Conservation - Reducing Water Usage

In addition to controlling gully erosion, check dams also serve to slow the movement of water, allowing increased percolation into the soil. Just above a check dam is a good place to put in a percolation structure. Silt that builds up behind the dam creates good farmland, which can be planted after the rains while it retains moisture. The following series of pictures show one farmer’s success with building a percolation tank just upstream of a series of check-dams.

It is similar to drip irrigation, but less expensive to install. The pitchers are the round earthen containers used in rural areas for water storage, ranging from 10 to 20 liters in capacity. This kind of irrigation is ideal for spreading plants such as gourd, pumpkin, and melon because few pitchers are needed per unit area. It is also very good irrigation for saplings, promoting deep root growth.

Soil and water conservation measures consist of agronomical and mechanical methods. Agronomic methods are supported with mechanical measures where land slope exceeds permissible limits and runoff gains erosive velocities.

The following boxes explain the nature of agronomic measures which are essential in inter-bunded or terraced areas. These practices enhance the utility value of all kinds of mechanical structures.

The Indian Institute of Technology, Madras, Technology for Sustainable Development and the Ecole Polytechnique Federale de Lausanne EPFL have produced a report titled Integrated Approaches for Sustainable Development in Water Resources Sector.

This report by the Advisory Council on Artificial Recharge of Ground Water, the Ministry of Water Resources, Government of India is divided into the following sections:

Part A: Improving Rice Productivity and saving Water through System for Rice Intensification (12 minutes)

This site includes a collection of documents, research reports and useful links on SRI . These include:

This report available on the  Watershed Support Services And Activities Network (WASSAN) site provides the details of three workshops organised by People's Science Institute (PSI) in October 2006 in the states of Uttarakhand and Himachal Pradesh as a first step towards sharing the experiences of System of Rice Intensification (SRI) method with the stakeholders group as well as assist the voluntary organisations in Uttarakhand and Himachal Pradesh to develop professional capabilities in the field of SRI method of paddy cultivation.

This document describes the drought situation in India over the years, the earlier perspective at drought management and the gradual change in perspective at managing droughts that evolved over the years.
