Desertification: migration, health, remediation and local governance

Abstract

the term desertification is often associated in minds with the advance of the desert, whose sand dunes invade slowly and inexorably into nearby fertile regions. This popular vision of desertification has lost any foundation in most scientific circles: African deserts do not continue their tirelessness towards the south, destroying everything on their way. Desertification is now defined as a mainly socio-economic phenomenon where natural resources deteriorate due to demographic pressures and unsustainable land use practices. The processes of building new desert regions where diversity is destroyed are strongly correlated with soil degradation, i.e. the progressive depletion of their physical, biological and economic potential. This soil degradation poses a serious threat to the overall productivity and consequently to the livelihood of the population. It reduces the diversity of plant and animal life, as it forces people to move and change their way of life, which also affects the diversity, culture, language and knowledge of the communities living in the degraded area.
