This paper attempts to explain the wildlife science-based tiger conservation pathway that integrates the keystone-umbrella species concept, landscape ecology and geographic information systems as major components to effectively devise wild tiger conservation priorities for the Bangladesh Sundarbans.
Data on surface ozone concentration compiled for a 10-year period from 1990 to 1999 for Pune and Delhi are analyzed in terms of its frequency distribution, annual trend, diurnal variation and its relation with various meteorological and chemical parameters. It is found that the surface ozone concentration range showing highest …
This paper describes the use of Global Positioning System (GPS) devices to map informal settlements in Cuttack, India in ways that enhance and support residents’ participation in the data collection and planning process. Rather than relying on remote sensing to identify informal settlement locations, each settlement is visited individually by …
The fragmentation of urban landscapes – or the inter-penetration of the built-up areas of cities and the open spaces in and around them – is a key attribute of their spatial structure. Analyzing satellite images for 1990 and 2000 for a global sample of 120 cities, we find that cities …
For over 16 years the Supreme Court has been hearing two major petitions concerning forests and wildlife. Writ petition 337/1995 filed by the Centre for Environmental Law (part of WWF) concerns protected areas (PAs) and writ petition 202/1995, is the omnibus forest petition widely known as the Godavarman case. The …
Conservation and wise use of wetlands has been given priority world over. India harbours diverse types of wetlands. This study highlights the findings of the national-level inventory and assessment of wetlands carried out using RESOURCESAT-1 LISS-III data of 2006–07 at 1 : 50,000 scale. A hierarchical system comprising 19 classes …
Contentious observations of Pleistocene shoreline features on the tectonically stable islands of Bermuda and the Bahamas have suggested that sea level about 400,000 years ago was more than 20 metres higher than it is today. Geochronologic and geomorphic evidence indicates that these features formed during interglacial marine isotope stage (MIS) …
Air pollution has long been a problem in the industrial nations of the West. It has now become an increasing source of environmental degradation in the developing nations of east Asia. China in particular, because of its rapid push to industrialize, is experiencing dramatic levels of aerosol pollution over a …
River Saraswati is believed to have flown through the Thar Desert, as reconstructed by several experts based on critical data gathered by them. A careful observation of the channel shows that in most of the places these are fault-controlled. Studies of palaeochannels in many parts of the world proved successful …
Chinese scientists claimed to have developed a system to monitor the movement of the Earth’s crust and predict earthquakes. The new system will be based on satellite navigation involving a network of 260 constant observing stations and 2,000 part-time observing stations with data-processing technology, according to the officials of the …
This study quantifies and maps the water footprint (WF) of humanity at a high spatial resolution. It reports on consumptive use of rainwater (green WF) and ground and surface water (blue WF) and volumes of water polluted (gray WF). Water footprints are estimated per nation from both a production and …
Gearing up to tackle possible chemical, biological, radiological and nuclear (CBRN) emergencies, research organisation DRDO is developing an array of ground-based and unmanned aerial systems to detect and map contamination zones in all geographical conditions. The Defence Research and Development Organisation (DRDO) is developing systems and equipments that would map …
The Nepal Electricity Authority (NEA) is using the latest technology called LiDAR (Light Detection and Ranging) technology to survey six reservoir type projects in the country. This is the first time that the hydropower is being surveyed through this air-based technology which is claimed to be the latest one globally. …
Smoke from burning forests and grasslands kills on average 339,000 people a year world-wide, an international research team said Sunday in the first systematic global health study of air pollution from wildfires. Every year, accidental and deliberate wildfires burn an area that, taken together, is larger than India. The dense …
The first global estimates of deaths from non-domestic smoke exposure are surprisingly high, say researchers, who warn the casualties will increase as temperatures rise because of climate change.
Nearly all our fresh water comes from obscure underground deposits – now satellites and radioactive isotopes are telling us how much we have to go round.
Himalayan glaciers and ice caps that supply water to more than a billion people in Asia are losing mass up to 10 times less quickly than once feared, a study published on Thursday reported. Based on an improved analysis of satellite data from 2003 to 2010, the findings offer a …
In the face of global overfishing of wild-caught seafood, ocean fish farming has augmented the supply of fresh fish to western markets and become one of the fastest growing global industries. Accurate reporting of quantities of wild-caught fish has been problematic and we questioned whether similar discrepancies in data exist …
India's State of Forest Report 2011 released by FSI provides special coverage to forest cover in hill districts, tribal districts and the north-east and also includes a new chapter covering detailed assessment of bamboo. The Forest Survey of India (FSI) has been publishing a series of biennial assessment report the …
