The populations of three species of Gyps vultures have shown a decline of more than 95% between 1988 and 1999 in the Indian subcontinent and are now classified as
The saltwater crocodile (SWC), Crocodylus porosus is perhaps the largest living reptile in the world. captive breeding of SWCs was initiated by the Forest Department of Orissa in 1975 at Dangmal, the Bhitarkanika Wildlife Sanctuary (BWLS). With increase in the SWC population, conflicts with humans and livestock also have been on the rise.
Chandrayaan-1, the first Indian planetary exploration mission, will carry out high resolution remote sensing studies of the moon to further our understanding about its origin and evolution.
Some of the Arabian Gulf states are busy developing several large, reclaimed islands and offshore townships. These structures are undoubtedly futuristic and the ideas are quite novel. However, there are serious issues of long-term sustainability of these townships.
A finite-element groundwater flow model, HYDRUS 2D, was used to simulate drawup and drawdown of piezometric pressure heads in the aquifer storage recovery cycles of varying buffer storage volumes and residence times in a highly brackish, semi-confined
aquifer under shallow water-table condition.
In the food web, herbivores are established to play an important role in maintaining the ecological health of an ecosystem by consuming a sizeable quantity of available vegetation. With the evolution of biodiversity conservation theory, grazing and browsing of herbivores has been generally treated as an unsustainable practice for long-term conservation of wild flora.
The 2004 tsunami has created havoc and excessive devastation in terms of human lives and loss of infrastructure in coastal areas of Andaman and Nicobar Islands, and rendered the soil and water resources salt-affected. In order to assess the changes in the relevant soil characteristics, viz. pH, electrical conductivity,
Although soils are generally considered to wet readily, some are actually water-repellent at the surface. This communication presents the recent progress in relating the severity of water repellency to different soil management practices and land uses under the lower Himalayan region of India.
The accelerated rate of increase in atmospheric CO2 concentration in recent years has revived the idea of stabilizing the global climate through geoengineering schemes. Majority of the proposed geoengineering schemes will attempt to reduce the amount of solar radiation absorbed by our planet.
