Background: Koshi flood of August 2008 in eastern lowlands of Nepal affected around 2.64 million people in India and Nepal, including 65,000 people and 700 ha fertile land in Nepal. It was calculated that 25% of the affected cultivated land of Shreepur, Haripur and western Kushaha villages in Sunsari district are still barren and remain filled with flood sediment of sizes from clay to sand even...

are fo ftony and fhallow as not to admit of the planting of fugar canes, with any profpedt of fuccefs, are generally found to anfwer belt for the aloe plant. The ftones, at leaft the larger ones, are firfl; picked up, and either packed in heaps, upon the moil fhallow, barren fpots, or laid round the field as a dry wall. The land is then lightly ploughed, and very carefully cleared of all noxiou...

Understanding the relationship between land-use/land-cover change (LULCC) and environment is seriously important to manage arid land. However, information on how environmental factors influence the LULCC patterns at different scales in arid area is lacking. This paper investigates the application of RS/GIS for detecting LULCC and assessing its impact on surface temperature in the Ismailia Gover...

Segmentation of vegetated areas is inevitable in precision agriculture and has high importance in urban area with social and environmental aspects. This paper addresses the segmentation of fused high resolution multispectral satellite images into distinct regions such as vegetation, buildings and barren land. Even though the IHS based fusion of satellite imagery improves the visual interpretati...

In the present study, an attempt was made to develop a conceptual land use strategy for regional development in four provinces of northeast border region of Thailand. A detailed GIS analysis was done to create comprehensive database including land use, soil suitability, socio-economic data, rainfall, etc. The current land use was studied using GIS, satellite remote sensing, field observation an...

Land degradation is becoming one of the severest environmental issues in the world, especially in developing nations. Land degradation, usually accompanied by soil erosion, always results in a decrease or complete loss of land productivity, and produces on-site and off-site pollution to soil and water. The methods for land reclamation are various, including physical, chemical and biological. Th...

Urbanization brings biophysical changes in the composition of the landscape. Such change has an impact on the thermal environment locally. The urban mosaic of land use and land cover is thus characteristically composed of local climate zones. The spatial variation in the land surface temperature across specific zone is studied for Bhopal city. The objective of the study was to understand how th...

In this study, we employed Geographical Information Systems and remote sensing techniques to investigate the impact of land-use/cover change on land surface temperature (LST) in a rapidly urbanisation city, Kunming in southwest China. Spatial patterns of LST and land use for 1992 and 2006 were derived from Landsat images to examine how LST responded to urban growth. Remote sensing indices were ...

Hyper spectral and multi spectral image analysis is the commonly used technique for land use and land cover classification. Effective use of the land cover can play a vital role in the development of country. Multi spectral satellites use passive sensor, hence the only source of energy involved in the acquisition of satellite imagery is the reflectance of the sun. In order to investigate the ro...
