Even if restricted to these meanings: conversion to a desert and irreversibility, the word desertification does not eliminate ambiguity. The question is not just a theoretical one; there is also a practical problem, which is to consider the realities as they appear to our common sense and to draw conclusions only after analysis of existing cases and components of the problem:
