- Outline
- The climate of Tamil Nadu State, India, is classified as semi-arid tropics,
in which annual precipitation is ranged from 700 to 1000 mm. In most of
the area except big river basin like Cauvery, irrigation activity had been
heavily dependent on tank system. As such system is designed to harvest
the surface water runoff, maintenance of the tank is essential for its
continuous use. In the ancient time, there was a maintenance system, “kudimaramathu”,
which was based on the village social structure. However, the changes of
the kind of crops in the command area and the movement of the people to
the cities encouraged well-water use and resulted in the decline of the
tank performance.
- Since 1980’s, local NGO and some international organization try to improve
the tank performance by promoting water user’s association. This research
project aims to assess the impact of such project on the agricultural water
use and livelihood of the farmers. Fieldworks in the selected villages
are conducted to analyze the water distribution in the tank command area,
and social simulation technique will be applied to assess the future sustainability.
