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.

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.

Laboratory reflectance spectra of 18 rock samples from the Precambrian basement of north east of Hajjah were measured and analyzed using the instrument of FieldSpec3 with spectral range 0.250-2.500um. The aim of this study is to use the spectral reflectance of rocks for mapping the mineral resources in the north east of Hajjah.

Watershed management plays a vital role in water resources engineering. Watershed based on water resources management is necessary to plan and conserve the available resources.

Invasive species have been the focus of environmentalists due to their undesired impact on the ecosystem. Spread of Lantana (Lantana camara L.), an invasive plant species, has been found in diverse geophysical environments causing a threat to the native flora.

This article deals with the demarcation of palaeochannels and mapping of integrated water resources in parts of Hisar district, Haryana using Indian Remote Sensing Satellite (IRS-1D) LISS-III Data of December 21, 2001. The ground water prospects of various geomorphic units have been assessed. Depth to water level and ground water quality maps were digitised and put in to GIS format.

The knowledge of the surface temperature is important to a range of issues and themese in earth sciences central to urban climatology, global environmental change and human-environment interactions.
