Impact of Community Based Tank Rehabilitation on Coastal Region: Community Based Tank Rehabilitation, Participatory Irrigation Management and Its Impacts on Coastal Agro-eco System. G. Poyyamoli

Freshwater is a finite and precious resource that is essential for sustaining life, as are the natural systems that provide and maintain its supply. Irrigation has been a vital input for food security and sustainable livelihoods, especially in developing countries during the Green Revolution, since it has increased income and improved health and nutrition, locally, and by bridging the gap between production and demand, nationally. As demand increases, this vital, irreplaceable resource is becoming increasingly scarce. A potential crisis is looming where available resources can no longer meet the growing needs. Over exploitation of groundwater by increased number of bore wells, culminates in seawater intrusion into the groundwater aquifers. To overcome such problems, the Governments of many countries worldwide have already recognized the need for transferring management responsibilities to water users. The major reasons for Participatory Irrigation Management Transfer are: improving irrigation system performance and productivity and programs of respective governments; enhancing the sustainability and reducing environmental impacts.
