Southeastern Spain, one of the driest areas in Europe, has established itself as one of the continent's main agricultural hubs. Despite having a climate marked by minimal rainfall and long periods of drought, this region has become the heart of the so-called “european vegetable garden.” Thanks to state policies, desalination plants, artificial reservoirs, and complex water transfer systems between river basins have been built, allowing vast previously unproductive areas to be irrigated.

Desertification is a process of land degradation - the process of land becoming infertile - that has been growing for years all over the world due to climatic causes and the direct effect of human action, such as deforestation, grazing and other practices that deplete water resources. In places like China, however, desertification also means literally the advance of the desert, which eats away at the land year after year. The Gobi desert is getting closer and closer to Beijing, contributing to increasingly intense sandstorms over the Chinese capital, leaving apocalyptic images like those of 15 March, with orange skies and pollution that exceeds up to 160 times the recommended limits for health.
