Goa

The report is based on a study carried out with the help of National Institute of Oceanography (NIO) and attempts to (1) assemble and analyse available information to describe and identify causes behind the flash floods, and (2) suggest measures to be adopted in Goa to minimise damage arising from similar episodes in future.

This document provides the details of the Rainwater Harvesting policy for the State of Goa and is aimed at providing guidance to all the concerned departments for the implementation of the policy in the state and information to the public.

The study by National Institute of Hydrology attempts to model seawater intrusion using FEFLOW, an interactive finite element simulation system in the coastal area of Bardez taluka in North Goa and evaluate the impact of increasing groundwater development on the phenomenon. Coastal tracts of Goa are rapidly being transformed into settlement areas and the poor water supply facilities have encouraged people to develop their own sources of water by digging or boring wells.

Goa is the second smallest state in India, with a total land mass of 3702 sq kms, and is one of the world's 12 bio-diversity hot-spots. While the largest industry is Tourism, conversely the second largest is mining. 8% of this state’s land is already under mining, mostly for iron ore, which is largely exported to China.

Where there is water, there is probably ore beneath.

Having trekked several times to Paikdev’s spring to gulp water pouring out of the moss-covered iron mouth, one would think the mysteries of the journey would fade. But, if anything, they have become more poignant – sitting here at this shrine to the snake deity of the Velip community in the village of Maina, in Goa’s Quepem District. It is here, amidst thousands of hectares of rolling forests, in the foothills of the Western Ghats, home to countless perennial springs and streams, wildlife and more, that a strange conglomeration of mining companies, politicians and real-estate developers are sharpening their collective sword. These activities were already afoot a year ago, with mining operations systematically destroying forests, because, as the government in Panjim stated at the time, the iron ore was needed by New Delhi to keep its nine-percent growth rate on track. This year, the message is no different.

The various initiatives taken up include watershed development work with the local community, repairing traditional water structures such as bandharas, installing water meters, automating saline water pump, harvesting rain water from the coke shed roof, waste water recycling and more.

The map shows that Tamil Nadu, Kerala, Karnataka, Goa, Maharashtra and Gujarat are high salinity zones, and Andhra Pradesh, Orissa and West Bengal are moderate salinity zones.

This papers models the saline water intrusion in the Bardez taluk of Goa.

The study is replete with hydrogeological maps and data. These include topographic contours, soil, landuse, rainfall, geology, location of observation wells etc.
