The island of Lanzarote is a volcanic territory in the Atlantic ocean. A large series of eruption in the XVIIIth century destroyed relevant agricultural landscapes. The islanders developed agricultural systems that allowed food production even under such harsh conditions (strong winds, arid land, nearly no water at all). Today some of these productions have earned quality labels (as the wine), but food production is not able to feed the local population and the sizeable tourist presence, so the island imports oil for its water desalting plants (there are plans to substitute it for renewable energies) and food.

Las Palmas
The Las Palmas landscape is a mix of black (for the volcanic island), green, blue and gray. The island capital has grown from the Spanish conquest in a compact form until the XXth century, when from the 1960s tourism changed completely the face of the islands. The steep slopes in most of the territory contribute to a high building density.
As oposed to other seaside cities, the peninsula was not the original settlement, but with the growth of the harbor areas and the relevance of the beach growth has reached it.
