Order of the National Green Tribunal (Eastern Zone Bench, Kolkata) in the matter of Sridhar Samal Vs State of Odisha & Others dated 06/03/2024. The matter related to pollution caused by Talcher Coalfield under Mahanadi Coalfields Limited in the course of its operation. It was said that on a daily …
The hydrology of the Ganga River is mainly characterized by high monsoon rainfall and seasonal variability in discharge flow. The study is focuses on both the up and down-streams of Farakka barrage. It has been executed with the help of Modified Normalized Difference Water Index using Landsat satellite images (2014), …
China launched a new civilian high-resolution mapping satellite on Monday from the Taiyuan Satellite Launch Center in northern Shanxi Province. The Ziyuan III 02 satellite took off on the back of a Long March 4B rocket at 11:17 a.m. Beijing time, according to the center. It was the 228th flight …
Widespread haze layers usually cover China like low clouds, exerting marked influence on air quality and regional climate. With recent Collection 6 MODIS Deep Blue aerosol data in 2000–2015, we analyzed the trends of regional haze pollution and the corresponding influence of atmospheric circulation in China.

Human impacts on fire regimes accumulated slowly with the evolution of modern humans able to ignite fires and manipulate landscapes. Today, myriad voices aim to influence fire in grassy ecosystems to different ends, and this is complicated by a colonial past focused on suppressing fire and preventing human ignitions. Here, …
Despite documented intra-urban heterogeneity in the urban heat island (UHI) effect, little is known about spatial or temporal variability in plant response to the UHI. Using an automated temperature sensor network in conjunction with Landsat-derived remotely sensed estimates of start/end of the growing season, we investigate the impacts of the …
In early spring the Baltic region is frequently affected by high-pollution events due to biomass burning in that area. Here we present a comprehensive study to investigate the impact of biomass/grass burning (BB) on the evolution and composition of aerosol in Preila, Lithuania, during springtime open fires. Non-refractory submicron particulate …
Global environmental change is rapidly altering the dynamics of terrestrial vegetation, with consequences for the functioning of the Earth system and provision of ecosystem services1, 2. Yet how global vegetation is responding to the changing environment is not well established. Here we use three long-term satellite leaf area index (LAI) …
Mountain regions and the important ecosystem services they provide are considered to be very vulnerable to the current warming, and recent studies suggest that high-mountain environments experience more rapid changes in temperature than environments at lower elevations. Here we analysed weather records for the period 1975–2010 from the Eastern Italian …
Six towns in Maharashtra—Lonavla, Shirur, Deolali Pravara, Umred, Vengurla and Sangola, made remarkable achievements over the last one year in waste disposal and management. A combination of proactive and punitive measures ensured that waste management is seen as part of a larger set of social problems and community initiatives.
Climate impact on landslide occurrence and spatial patterns were analyzed within the larch-dominant communities associated with continuous permafrost areas of central Siberia. We used high resolution satellite imagery (i.e. QuickBird, WorldView) to identify landslide scars over an area of 62 000 km. Landslide occurrence was analyzed with respect to climate …
This book describes some key global water challenges, perspectives for remote sensing approaches, and their importance for water resources-related activities. It presents eight key types of water resources management variables, a list of sensors that can produce such information, and a description of existing data products with examples. This book …
The Sundarban of India and Bangladesh (about 6000 km²) are the only mangrove forests inhabited by a sizeable population of tigers. The adjoining area also supports one of the highest human densities and experiences severe human-tiger conflicts. We used GPS-Satellite and VHF radio-collars on 6 (3 males and 3 female) …
We have addressed the question of whether the massive deficit of 42% in rainfall over the Indian region in June 2014 can be attributed primarily to the El Niño. We have shown that the variation of convection over the Northern part of the Tropical West Pacific (NWTP: 120–150E, 20–30N) plays …
The world-famous Rajaji National Park, Uttarakhand, India has recently been notified as Rajaji Tiger Reserve (RTR). This Protected Area is now the 48th Tiger Reserve in the country and the second in Uttarakhand. Though RNP was established in 1983, final notification for the Park was issued in 2013 because of …
Accurate estimation of the groundwater budget requires good estimate of flux across the boundary of a region. Different methods and techniques are available to estimate recharge to groundwater; however methods for estimation of flux across boundaries are not available. The present article represents a GISbased methodology to estimate the groundwater …
Evidence from ecological studies, eddy flux towers and satellites shows that many tropical forests ‘green up’ during higher sunlight annual dry seasons, suggesting they are more limited by light than water. Morton et al. reported that satellite-observed dry-season green up in Amazon forests is an artefact of seasonal variations in …
Ocean ecosystems play a critical role in the Earth's carbon cycle and the quantification of their impacts for both present conditions and for predictions into the future remains one of the greatest challenges in oceanography. The goal of the EXport Processes in the Ocean from Remote Sensing (EXPORTS) Science Plan …
Following a record winter in many ways, Arctic sea-ice cover seems poised to reach one of its smallest winter maxima ever. As of 28 February, ice covered 14.525 million square kilometres, or 938,000 square kilometres less than the 1981–2010 average. And researchers are using a new technique to capture crucial …
Air pollution is associated with morbidity and premature mortality. Satellite remote sensing provides globally consistent decadal-scale observations of ambient nitrogen dioxide (NO2) pollution. The researchers determined global population-weighted annual mean NO2 concentrations from 1996 through 2012. Original Source
A new paper published by the Global Warming Policy Foundation explains how statistical forecasting methods can provide an important contrast to climate model-based predictions of future global warming. The repeated failures of economic models to generate accurate predictions has taught many economists a healthy scepticism about the ability of their …
