Global warming: Gangotri Glacier Receding

Indian Space Research Organisation (ISRO) in a satellite imagery based document released on 25th November 2009, stated that the Gangotri glacier has receded 1.5 km in the last 30 years. Nearly 30 km long, upto 2.5 km wide and holding 27 cubic km of ice, the Gangotri glacier is one of the largest in the Himalaya. At its downward end lies Gomukh, from where the holiest of Indian rivers, Ganga emerges. Gangotri – 18 kms below, is a sacred pilgrimage site visited in hordes by followers of Hinduism....

Ecosystem Under Threat: Lakshadweep

Lakshadweep, islands of coral origin, are mainly atolls except for one platform reef of Androth. The height of the land above the sea level is about 1 to 2 meters. The Lakshadweep group of islands comprise of 36 islands (11 inhabited, 16 uninhabited with attached islets, 4 newly formed islets and 5 submerged reefs), covering an area of 32 sq km with Kavaratti as the Capital. According to the provisional population data of 2001 Census, Lakshadweep has a population of 60,595 persons. More than 93 per cent...

Climate change

The Himalayan ecosystem has 51 million people who practice hill agriculture and whose vulnerability is expected to increase with changing climatic regime. The National Action Plan on Climate Change envisages a National Mission for sustaining the Himalayan ecosystem to evolve management measures for sustaining and safeguarding the Himalayan glacier and mountain ecosystem. An observational and monitoring network for the Himalayan environment will be established to assess freshwater resources and health...

Methane Emission

As per the inventory made by the Ministry of Environment and Forests (MoEF), rice contributes almost 23 per cent of total emissions from agriculture. Recent research, using better characterisation of agro-ecosystem properties, indicates that this fraction could perhaps be even lower, although a significant proportion of emission is inevitable from rice fields which remain flooded. There is however scope of reducing emissions from irrigated rice fields by mid-season drainage or alternate drying instead...
