Thanks to the availability of satellite data archives covering more than a decade, Permanent Scatterer SAR Interferometry (PSInSAR) nowadays represents one of the most powerful techniques capable of retrieving surface displacements of either natural (rock outcrops) or man made objects (buildings, infrastructures) already present within the surveyed area, acting as permanent radar reflectors.

With growing urban expanses, one of the pre-requisites for effective governance is Urban Information Systems (UIS) with content down to individual properties (and individuals).

Secondary salinisation is the most harmful and extended phenomenon of the unfavourable effects of irrigation on the soil and environment. An attempt was made to study the impact of poor quality ground water on soils in terms of secondary salinisation and availability of soil nutrients in Faridkot district of Punjab of northern India.

The study area is one of the watersheds of North Pennar basin, covering an area of 570 km2 and lies between latitude 13

Over the past several decades, satellite surveillance with increasingly sophisticated instruments has enabled scientists to better visualize the complex fluctuations of several pollutants as they make their way around the Earth. One aspect of this research has focused on directly correlating satellite-observed concentrations of pollutants in the atmosphere with those at ground level.

This study examines the annual, seasonal and diurnal variations in the ambient concentrations of ozone at a suburban site of Varanasi, India, during 2002-2006. Prominent seasonal variations in ozone concentrations were recorded. Ozone concentrations were higher during the warmer months.

The ground water samples collected from different tehsils of Ujjain district were analysed in the laboratory for electrical conductivity (EC), pH, cations (Na+, K+, Ca2+ and Mg2+) and anions (CO32-, HCO3-, Cl- and SO42-). The ground water quality map of the district was generated using ERDAS-IMAGINE 8.7 software showing different categories.

During the past century through food and energy production, human activities have altered the world's nitrogen cycle by accelerating the rate of reactive nitrogen creation. India has made impressive strides in the agricultural front, in which N fertilizer plays a major role.

The lush tropical rainforests of Papua New Guinea are not the unspoilt haven that many believed till now. In fact, they are disappearing faster than those in the Amazon.
