The volcanoes, although they caused destruction and losses of cereals and livestock, brought about new forms of agriculture using volcanic materials. On the island of Lanzarote, following the eruption of the volcano in the 1730s, a process of agricultural transformation took place. The technique of sanding, which consisted of covering the soil with a layer to buffer the climatic conditions, found its maximum expression on the island with “lapilli”, a volcanic material with a hygroscopic effect (accumulation of ambient humidity). With this method, the soil was covered with lapilli, where the seeds were planted, and ploughed. With the volcanic material, the scarce autumn rains were sufficient to irrigate crops that required water, such as vegetables, pulses or potatoes.
