6. CONCLUSION 
The prime aim of this study is to demonstrate the potentiality 
of remote sensing technology for desertification status 
mapping. Based on the methodology and classification system a 
desertification status map has been prepared for Kathua micro- 
watershed. The multi-temporal satellite data reveals that as 
result of anthropogenic factors vegetal degradation is very 
prominent in this region and 86 percent of area is affected by 
vegetal degradation and 8 percent of the region is reeling under 
salinity.

ANNEXURE - I 
CLASSIFICATION SYSTEM FOR 
DESERTIFICATION STATUS MAPPING 
A three level hierarchical system of classification has been 
followed for the desertification status mapping. This is 
explained as bellow: 
LEVEL 1: Land Use/ Land cover — 
The following categories have been identified as below: 
Agriculture - Unirrigated 
Agriculture - Irrigated 
Forest 
Grassland/ Grazing land
