Description Over-exploitation of natural resources for meeting the increasing demand for food, fuel, and fiber of the
ever growing population has led to environmental degradation and calls for their optimal utilization based
on their potential and limitations. Information on the nature, extent, and spatial distribution of natural
resources is essential. Spaceborne multispectral measurements made at regular intervals hold immense
potential of providing such information in a timely and cost-effective manner, and facilitate studying
dynamic phenomenon. The geographic information system (GIS) provides an ideal environment for
integration of information on natural resources with the ancillary information for generating derivative
information which is useful in decision making. The study was taken up to generate the action plan for land
and water resources development and to monitor the progress of its implementation in the Adarsha
watershed, Kothapally, Ranga Reddy district, Andhra Pradesh, India. The approach involves generation
of thematic maps on various natural resources through a systematic visual interpretation of satellite data,
integration of such data with the ancillary information and generation of action plan in the GIS
environment, and monitoring vegetation development as a sequel to implementation of action plan by
generating Normalized Difference Vegetation Index (NDVI) from the Indian Remote Sensing Satellite (IRS-
1C/-1D) Linear Imaging Self-scanning Sensor (LISS-III) data. Soil erosion by water is the major land
degradation process operating in the watershed. There has been an improvement in the vegetation cover
owing to implementation of various soil and water conservation measures, which is reflected in the NDVI
images of pre- and post-implementation periods
