Desertification, the land degradation of drylands due to diverse factors including climate variations and human activities, is among the most serious environmental challenges facing the world today. Risk tremendously increases when desertification processes synergise with climate changes and new drivers are added to already degraded areas, leading to unknown situations. How will local societies cope with these environmental changes. This paper presents examples from the Central Andes, with special emphasis on irrigated viticulture and hydropower generation. It discusses some climate change scenarios and the desertification status in relation to ongoing processes affecting both the economy and the environment of the Andes and the settlements in their area of influence. Facing this changing scenario is essential to discussing and agreeing upon a proper development model for drylands. With this in mind, some different scenarios are presented.
