METHODOLOGY |
An integrated approach involving the determination of the present status of water body and socio-economic conditions of the households dependent for day to day needs (fuel, food, fodder, etc.) was undertaken to evolve appropriate restoration, conservation strategies and better management policies.
The samples were collected from the outlets (two outlets - samples 1 and 2), center (sample 3) and inlet (sample 4) of the Yennehole tank and analysed for various physico-chemical-biological parameters according to APHA (1985) and NEERI methods (1998).
Socio-economic valuation was undertaken to quantify the aquatic system values and to determine the economic dependency of the people living in the surrounding areas on the lake. Approximate valuation of resources based on their use values (human interactions with the aquatic resources mainly fisheries) and non-use values (no human interactions with the aquatic resources) were determined by conducting interviews with local communities. A random survey of the houses around the lake was carried out using a standard questionnaire designed for this purpose.
