摘要

Age-old irrigation practices, uncontrolled exploitation of groundwater for aquaculture with an urge to make a fast buck at the expense of coastal ecosystem have caused irreversible damage to major segments of our coastal belt. Parts of East Godavari, Krishna, Prakasam and Nellore districts of Andhra Pradesh, coastal segments of Pondicherry, Tamil Nadu and Orissa have experienced considerable damage to the quality and quantity of groundwater. Since it is essential for us to know in detail the present nature of the groundwater regime to arrest, if not reverse the damage, we have to introduce practical scientific solutions that have received a good amount of success in different parts of the world. As a part of this exercise, it is essential that the direct discharge of groundwater into the coastal zone receives increased attention in the years to come, as it is known that this process represents an important pathway for material transport between land and sea. It is essential to note that groundwater discharge often contains higher concentrations of dissolved nutrients and other components than does river water. Since there is considerable decrease in the discharges into the river system due to various reasons, including significant fluctuations in the monsoon activity due to regional and global effects and non-scientific exploitation of surface water bodies like ponds and tanks, the role of groundwater has increased enormously in maintaining good health of the coastal ecosystem.
