What is disertivication?

Answer 1

Disertivication appears to be a typographical error, as there is no widely recognized term "disertivication." If you meant "desertification," it refers to the process by which fertile land becomes increasingly arid and desert-like, often due to factors like climate change, deforestation, and unsustainable land management practices. This phenomenon can lead to the loss of biodiversity, agricultural productivity, and water resources, significantly impacting ecosystems and human livelihoods.
