Almeria’s geographical location come one of the world’s areas that has experienced the most dramatic environmental changes in the last decades (UNEP, 2005). The incredible socio- economic change provided by this agro economic transformation has been of such extent that it is often referred to as “miraculous” (Sánchez, Aznar, Garcia, 2011). The introduction of greenhouse agriculture came hand in hand with important flows of immi- gration since this type of agriculture is extremely dependent on manpower. The “model of Almeria” could be an exemplary model for adaptation to climate change in dry regions. In this chapter, *.
