The Kanwar Lake in Begusarai district is one of the Asia’s largest freshwater oxbow lake and eco-friendly natural lakes which attracts a variety of migratory birds. It has been shrinking at an abnormally high rate. Despite being designated as wildlife sanctuary, this wetland is under threat from anthropogenic pressures. An …
The study estimated, for the first time, the greenhouse gas emissions associated with cattle raising in Brazil, focusing on the period from 2003 to 2008 and the three principal sources: 1) portion of deforestation resulting in pasture establishment and subsequent burning of felled vegetation; 2) pasture burning; and 3) bovine …
This report presents the key findings on forest land use and land-use change between 1990 and 2005 from FAO’s 2010 Global Forest Resources Assessment Remote Sensing Survey. It is the first report of its kind to present systematic estimates of global forest land use and change. The ambitious goal of …
A new data set of middle- and upper-stratospheric temperatures based on reprocessing of satellite radiances provides a view of stratospheric climate change during the period 1979–2005 that is strikingly different from that provided by earlier data sets. The new data call into question our understanding of observed stratospheric temperature trends …
A new model of glacial isostatic adjustment used in conjunction with GRACE satellite data suggests that ice loss from Antarctica is contributing 0.19 millimetres per year to global mean sea level, which is substantially less than previous GRACE-based estimates.
Being a low laying deltaic country, the morphological changes of the coastal zones of Bangladesh become a major social, economic and environmental concern. In this study, images of Landsat satellite during 1989-2010 are analyzed to detect the variation of shoreline positions. The western-central coast has been divided into different segments …
Satellite data are invaluable for mapping India's remaining forests, but their coarse resolution limits the information they can provide for protection purposes (Nature 489, 14–15; 2012). For example, individual tree species cannot be identified from satellite data. (Correspondence)
The objective of this paper is to examine the methodological issues such as scale, baseline reference, measuring, monitoring, and verifications of the REDD+ project in context to India. Remote sensing and GIS based methodology will help in estimating carbon stock of the benchmark year as well as for future temporal …
The Nagaon district in Assam is in a sub-humid region with a greater part of the district comprising alluvial soil ranging from pure sand on the banks of the Brahmaputra to stiff clay. The area is subjected to frequent flooding by rivers during a spell of 4 months in a …
Tropical cyclones over the Arabian Sea in the pre-monsoon season (May–June) have intensified since 1997 owing to significant reductions in storm-ambient vertical wind shear (VWS) in the troposphere; these reductions have decreased on average by about 3 m s−1 from the pre-1997 epoch (1979–1997) to the recent epoch (1998–2010)1. The …
Making history in its space odyssey, India on Sunday successfully launched its 100th mission with its workhorse PSLV-C21 placing in orbit two foreign satellites in a flawless flight from the spaceport here. The third wholly commercial launch was a textbook mission as ISRO’s Polar Satellite Launch Vehicle placed in orbit …
Scientists in the Arctic are warning that this summer's record-breaking melt is part of an accelerating trend with profound implications. Norwegian researchers report that the sea ice is becoming significantly thinner and more vulnerable. Last month, the annual thaw of the region's floating ice reached the lowest level since satellite …
From regulating climate systems to offering food and medicines, to being home to many plants, animals, and indigenous people, rainforests are not only a local ecosystem but their benefits extend globally. Adding to its effects is new research that shows rainforests have a huge impact on rainfall. A team from …
Ten central African countries have come together to protect the Congo Basin rainforest — the world's second largest rainforest — from severe deforestation, through implementing improved national forest monitoring systems and boosting regional cooperation. The 18-month project, launched on 26 July, is managed by the Central Africa Forests Commission (COMIFAC) …
Delhi-NCR is fast becoming an “island of heat”, as surface temperatures have risen by 2-3 degree Centigrade in the past three decades, says a new study. With a population of 21 million, Delhi-NCR has become hotter than it was 30 years ago largely due to industrialisation, rising population and massive …
Sri Lanka will start an aerial survey of its mineral resources, said Geological Survey and Mines Bureau chairman Dr. M.J. Wijayananda. A South African company had been selected through a tender procedure to conduct the survey. The survey will cost $ 17 million and is expected to take one and …
A central paradox of the global monsoon record involves reported decreases in rainfall over land during an era in which the global hydrologic cycle is both expected and observed to intensify. It is within this context that this work develops a physical basis for both interpreting the observed record and …
In this study, Gangotri glacier was monitored using Indian Remote Sensing (IRS) LISS-III sensor data in combination with field collected snow-meteorological data for a period of seven years (2001–2008). An overall decreasing trend in the areal extent of seasonal snow cover area (SCA) was observed. An upward shifting trend of …
