La Aldea de San Nicolas is a municipality in the western part of the island of Gran Canaria, with a population of 8.626. It is surounded by protected spaces related to its arid and volcanic landscape. It has 2.300 hectares of dry farming, divided in 111 farming units, and 381 hectares of irrigated land, divided in 230 farming units. As water is always scarce on the island, it comes from desalting plants, and a large share of irrigated land is under plastic grenhouses. As usual, greenhouses are mounted or dismantled according to the farmer’s profit expectations, and they are a hit in the landscape, creating a haphazard patchwork with traditional agriculture and settlements.
