India Wetlands Review 2017: Important Court Orders

SUPREME COURT The Supreme Court of India is hearing a matter Writ Petition(s)(Civil) No(s). 230/2001 in which there have been several orders of consequence this year (e.g. 8 Feb 2017 & 16 Aug 2017) for protection of wetlands.  In spite of several directions for identification, preparation of brief documents, implementation of rules 4, notification of wetlands under the Wetlands Rules 2010, hardly any progress has happened.

Rule 4 of Wetlands Rules 2010 applicable to Wetlands of size ≥2.25 ha 

 “National Wetland Inventory & Assessment” was filed in SC. This Brochure indicates on page 11 that 2,01,503 wetlands have been mapped at 1:50,000 scale. All these wetlands have ‘an area of more than 2.25 hectares’. As a first step, the ‘Brief Documents’ with regard to these 2,01,503 wetlands should be obtained by the Union of India from the respective State Governments in terms of Rule 6 of the Wetlands (Conservation and management) Rules, 2010.

Chandigarh Wetlands Review 2017: Sukhna Lake Facing Multiple Problems

The man-made, rain-fed lake Sukhna, located in Sector-1, Chandigarh, was built in 1958 at the cost of Rs 1 crore by damming Sukhna rivulet. Over the years, the lake has become integral part of Chandigarh’s cultural life and recreational activities. At the same time, ever since its creation, it is also in the centre of natural and man-made problems.

For years, pursuing Punjab & Haryana High Court (HC), Chandigarh directives, Union Territory Administration Chandigarh (UTAC), has been taking several measures to restore the lake’s falling glory. However siltation, catchment degradation, water evaporation, weeds infestation, lack of rain, pollution all seems to have become persistent threats jeopardizing the lake eco-system.

All through the year 2017, the lake remained in news for various reasons. UTAC has pumped ground water to fill the dry lake. There are plans to transfer Bhakhra dam water to keep the lake saturated during lean season. HC Judges have visited places around the lake to observe progress on ground of its orders issued to revive the lake. The court has also cancelled a Tata Group real estate project proposed in Lake Catchment in violation of norms. Despite all this, the gradual deterioration of lake eco-system is going on. Here we try to capture various developments in 2017 regarding Sukhna lake.

DRP News Bulletin 12 June 2017 (Rain Bearing Clouds Thinning Out Over India: IMD Study)

A recent IMD study has found that rain-bearing clouds have been thinning out across the country over the last 50 years. The study, published in the IMD journal Mausam, shows that between 1960 and 2010, annual mean low cloud cover (responsible for the bulk of the rainfall) over India has been decreasing by 0.45% per decade on an average.

According to the study, the number of rainy days is also declining during the monsoon season at an average rate of 0.23 days for every decade. This means that the country has lost approximately one rainy day over the last five decades. The study found that while the number of rainy days is decreasing, there is not much change in the total amount of rainfall. This shows a trend towards shorter, heavier bursts of rain.

That is bad news, because heavier raindrops can dislodge wheat and rice grains from their stalks while on the farm. It also means rainwater flows down a slope that much faster instead of percolating underground.

Meanwhile, a new NASA study has warned  the amount of rainfall in the Earth’s tropical regions will significantly increase as the planet continues to warm. As per study rainfall is not related just to the clouds that are available to make rain but also to Earth’s “energy budget” — incoming energy from the Sun compared to outgoing heat energy. High-altitude tropical clouds trap heat in the atmosphere. If there are fewer of these clouds in the future, the tropical atmosphere will cool.
