What is desertification? I have heard the term but really don't know what it means. From my reading it is where dryland used for agriculture and other purposes loses its economic and biological productivity and usually results from climatic variability (change) or unsustainable human practices.
Some of you might now be wondering...'what are drylands'? Well, these are lands that can be productive with limited input from irrigation or natural precipitation. This does not however mean that they are resilient and can remain productive with no or limited rain, it means that they are adapted to a particular level of natural precipitation or human intervention and when this changes they are no longer productive.
I have heard this term mostly associated with Africa and I would like to learn more about the causes of this situation both in Africa and in other locations.
