The book considers desertification as a cause-effect of environmental degradation that causes
global environmental changes and the current climate crisis. Desertification affects
sustainability and is one of the most severe socio-environmental problems on a global regional
and local scale and in magnitude. It is a complex and interdisciplinary phenomenon with
socioeconomic historical and ecological aspects. The book dealt with themes such as
Anthropocene and limits of balance on Earth Global Environmental Changes Climate Crisis
Desertification: concepts myths and reality Causes and impacts in the world considering
international technical-scientific assumptions guided by historical practical and conceptual
issues. Currently desertification (land degradation in arid semi-arid and sub-humid regions
resulting from various factors such as climate variations and human activities) occurs in
different continents and associates with land use and environmental and climate changes. This
is a question of interest to the political management of the territory. The compendium goes
beyond the conceptual approach and brings case studies with depth and a holistic view.
Watersheds for example were treated as synthesis cells of environmental assessments and
territorial units to develop public policies to manage natural resources and mitigate soil
salinization and geochemical contamination. Besides the correlation between desertification and
climate as a natural design its harmful consequences for the planet are correlated with the
most affected areas associated with poverty environmental conflicts and land tenure. The book
considers several studies and a wealth of qualitative and quantitative data pointing out about
3.6 billion hectares affected and more than 2.6 billion people affected worldwide.
Desertification areas demand priority attention and greater scientific clarification not
contaminated by other interests surpassing the boundaries of sectorial and empirical
explanation and not dissociated from natural x human processes. The book proposes to be
holistic with an assessment of the totality!
