Seventy 2 The Parties to this Convention, Affirming that human beings in affected or threatened areas are at the centre of concerns to combat desertification and mitigate the effects of Desertification is defined scientifically. Discussion: desertification as a world-wide and historical phenomenon. as the entire or pa rtial deterioration of one or more aspects of terrestrial ecosyst ems, resulting. causes of desertification include overgrazing, over cultivation, deforestation and salinization on irrigated cropland. The most commonly cited forms of unsustainable land use are over-cultivation, over-grazing, deforestation, and poor irrigation practices. Home to a third of the human population in, drylands occupy nearly half of Earth’s land area.
