Abstract: This paper studies the agrarian change occurred in Lanzarote after the volcanic eruptions in 1730-1735. Population censuses and tax records are the main sources. This island lacks in water resources and is extremely arid. Its islanders grow cereal and practice extensive cattle farming, and migrations were frequent in drought years. The agrarian change caused by the volcanoes transformed this land management model. The lavas destroyed a part of the arable soil and the rest was covered by a thick layer of volcanic sand (lapilli) which, thanks to its hygroscopic effect, helped certain plants sprout again and grow more vigorously. Natural enarenado had come into being. The islanders proceeded to develop this technique, what allowed them to cultivate species (vine, corn, potato) that had previously been severely limited by the dry terrain.
