Oceans and Coasts

The report by Institute for Defence Studies and Analyses is premised on the fact that India is facing a serious water resource problem and is expected to become 'water stressed' by 2025 and 'water scarce' by 2050. It raises fundamental questions about the forces driving water demand and the political dynamics of riparian relations, both in terms of hindrances and opportunities, amongst states in the subcontinent. Rivers, a crucial source of water resources, physically link upstream and downstream users and at the same time create barriers.

The Mizoram state has three types of (natural) lakes: valley lakes, tectonic/landslide lakes and artificial reservoirs, but the only lake of significance is Palak Dil, which is a natural lake in a depression in the hills. Palak Dil may possibly be a combination of valley and tectonic lakes. Locally in Mizoram, lakes are called dils. There are many such dils scattered all over the state, but they are tiny pools or marshy depressions such as Rengdil, Tamdil and Mampui Dil (Choudhury 2002). The Palak Lake is situated within the Mara Autonomous district Council, which is a region inhabited by the Mara Tribe. The Maras are distinct from the majority Mizos and in the Mara language the Palak Lake is referred to as Pala Tipa.

The Ministry of Environment and Forests (MoEF) has issued the draft CRZ Notification, 2010 under the Environment (Protection) Act, 1986 on 15th September, 2010 inviting suggestions and objections from public within 60 days from date of its issue. The following are the new additions to the original 1991 notification:

The central government has declared the coastal stretches of seas, bays, estuaries, creeks, rivers and back waters which are influenced by tidal action (in the landward side) up to 500 mts. from the High Tide Line (HTL) and the land between the Low Tide Line (LTL) and the HTL as “Coastal Regulation Zone” (CRZ), on 19.2.1991.

This paper published in the journal Conservation and Society reassesses/debates the decision taken by the government to dredge a new sea mouth in the Chilika Lake in Orissa, India, which was based on Geographical Information Systems (GIS) studies.

The paper argues that decisions such as these need to be understood and evaluated by taking into consideration not only the underlying technical aspects, but by also exploring the political and historical contexts in which decisions are taken. 

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.

• WIO demands the Government of Orissa to come out with a White Paper on water first and then decide on new allocations.
• No new industries should be allowed to draw water unless this White Paper prepared and made public.
• That Orissa is a ‘Surplus Water’ state is a ‘myth’.
