Desertification in arid and semi-arid regions: causes and consequences

Meer over het boek

The book explores the alarming phenomenon of desertification, detailing its historical context and current implications across the globe. It contrasts natural desertification, exemplified by the Sahara's transformation from grassland to desert over millennia, with the accelerated human-induced processes threatening ecosystems today. Key factors include deforestation, overexploitation of resources, and climate change, which collectively contribute to the degradation of arid and semi-arid lands. The text emphasizes the urgency of addressing these environmental challenges to prevent further loss of vegetation and biodiversity.
