At the edges of deserts, reduction in vegetative cover due to low rainfall may lead to reduced precipitation. this leads to expansion of deserts. is this positive feedback loop, negative feedback loop, neither, or no answer provided?

Positive Feedback Loop

Explanation:

The expansion of desert area and land use elements are significant drivers of a ecological system moving to a state of desertification.  

This move is regularly supported by positive feedback loop which balances out the framework in the new condition of environment.The desertification is the adjustment in soil properties, vegetation or atmosphere, which can  bring about a constant loss of environmental benefits that are major to continuing the life.  

The desert expansion influences huge dry land regions around the globe and is the real reason for worry in human culture.  

The multidisciplinary way to deal with understanding drivers and criticisms of worldwide desertification is roused by our expanding requirement of worldwide nourishment creation and to reasonably oversee environments in region of environmental change.
