An attempt was made to assess the land condition while taking into consideration environmental and socio-economical parameters that could be drivers of ongoing land degradation processes. Many of these variables have spatial and temporal characteristics and can therefore be monitored through GIS-based tools thus contributing valuable information for assessing land degradation risk.

In recent decades, multi-spectral and hyper-spectral remotely sensed imageries with high and modern spatial resolutions at sufficient time-series interval have been developed. This allows for detecting crop types and its distribution over large areas and at short time intervals. Among the advantages of remote sensing technologies are its cost effective evaluation over extensive areas and the ability to provide reliable information on land surface conditions. This is useful also for areas with sporadic information on the spatial extent of croplands effected by for instance water scarcity.

With only 7 percent of agricultural land, Tajikistan is a mountainous country located at the heart of Central Asian region, prone to desertification, salinization, soil erosion and forest loss. The first step to address the issue is to measure the real cost of degradation of the agricultural land. The full costs of land degradation are believed to be high and increasing but they are also difficult to measure.
