Mangroves are salt tolerant plants that occur between 32°N and 38°S latitudes. Mangroves play an important role in stabilizing shoreline and protect the coast against storm surges and heavy tides. Though the mangrove inventory has been done earlier in India using satellite data but no systematic attempts has been made to map the mangroves at the community level for the entire country. The present paper reports the mangrove inventory at community level for India using Resourcesat-1 satellite data. State wise inventory on the mangrove area and the dominant communities are presented.

An attempt has been made to investigate occurrence and bioaccumulation of metallic elements in river Ganga water at Allahabad using laser induced breakdown spectroscopy technique. The recorded spectrum shows the presence of atomic lines of the micronutrients (Ti, Si, Cr, Co, Br, Ba, Sr), macronutrients (H, N, Na, O, K, Ca, Mg, Cl, C) and toxic metals (Hg, Pb, Cd).

This recent study published by Department of environmental sciences, JNU points out alarming levels of aerosol and heavy metals in Delhi's air.

Freshwater basins are vulnerable to human-induced change for a number of reasons. The change detection study of Ansupa lake, Orissa was carried out by using multi-temporal satellite data clearly indicates the decrease in wetland area. Due to high anthropogenic pressure, the wetland is shrinking day-by-day.
