It is expected that climate change will promote conditions of low rainfall and desertification in substantial areas of southern Europe and the Outermost Regions of the European Union. The general objective of the project is to test innovative fog collectors and innovative typologies of reforestation that, based on fog water collection, do not significantly increase the carbon footprint compared to the traditional typologies, taking into account: their effectiveness, costs and benefits, including as far as possible, the externalities they produce.
