Abstract

Resource utilization and resource degradation varies with changes in spatial and temporal characteristics of resources.It is important in resource management to identify areas which are prone to degradation(hot-spots of resource utilization),and to apply specific management to such areas accordingly,in order to prevent resources and environment degradation.The present study is a pilot project carried out at a micro-watershed in northern India to exploit the method of mapping the hot-spots of the resource utilization.Four parameters are considered practically as the major factors,viz.importance of the resource,resource requirement,resource accessibility and disturbance index.GIS and RS are employed for the spatial analyses.As a result,the study area is divided into three hot-spot resource utilization zones:high critical area,medium critical area and low critical area.These reflect spatial differences of resources utilization and resources degradation from high to low respectively.
