Land use and land cover changes due to human activities in a time sequence. Detection of such changes may help decision makers and planners to understand the factors in land use and land cover change in order to take effective and useful measures. Remote sensing and GIS techniques may be used as efficient tools to detect and assess land use change.

In the present study, efforts have been made to identify and map areas affected by various soil degradation processes in Hanumangarh district of western Rajasthan. Soil degradation processes were identified by using IRS-1B satellite image of the year 1998, SOI topsheets, ground truth verification and soil studies.

Planning based on agro-ecological zoning aims at scientific management of regional resources to meet the food, fibre, fodder and fuel wood requirements without adversely affecting the status of natural resources and environment.

The planning of conservation measures to conserve water and soil resources taking hydrological planning unit as micro-watershed is considered to be effective.

Presents study consists the results of the Sun photometer measurements of aerosol optical depth (AOD) over the northern Arabian Sea during December 4-17, 2004 along with OCEANSAT-1 Ocean Colour Monitor (OCM) data derived AOD estimates. In-situ AOD ranged between 0.15-0.38 at 500-nm wavelength (with a mean of 0.274).

Vegetation condition monitoring has been done from 1975 to 2000 in the waste dump of Haizhou opencast coalmine area, China, using remote sensing techniques with the objective of improving our understanding of the temporal and spatial variation of vegetation recovery in the mining dump.
