Remote Sensing and Desertification

Posted by Simon Adebola on December 21, 2010

“Satellite imaging technology has been recognized as playing an important role in achieving this objective by using these methods for monitoring the areas most at risk to support land and water management decisions.

Earth observation (EO) satellite technologies allow land degradation processes to be monitored over time. Monitoring desertification, land degradation and droughts requires continuous evaluation, some of which can be retrieved with earth observation technologies and state-of-the-art geo-spatial applications.

High-spectral resolution satellite imagery can dramatically increase the accuracy of dryland monitoring. Hyperspectral imagery incorporated with field and laboratory data for analysis can be used to derive more quantitative and specific soil properties directly linked to soil degradation status, such as soil chemical properties, organic matter, mineralogical content, infiltration capacity, aggregation capacity, and runoff coefficient.

Combining satellite image data with weather data, numeric models and geographical information systems (GIS) are used to create standardized geo-information products.”
