Nonetheless, with the loss of traditional agro-ecosystems and the rationale that guides them, as has happened in Europe, an historical research approach can have a decisive role to play in recapturing this knowledge. In this article we study the evolution of a typical Mediterranean agro-ecosystem during the last 250 years, supporting the claim that high diversity and the internalization of energy ﬂows and nutrient cycles found in traditional agriculture, are not only characteristics of the greatest sustainability of such systems, but are based in the need for additional land in production. This claim requires the dedication of land to diverse and complementary uses that leave a footprint on the landscape. Organic agriculture needs to consider this “land cost”, meanwhile trying to minimize it in order to improve its actual degree of sustainability.</style></abstract><issue><style face="normal" font="default" size="100%">2</style></issue></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Prieto, M.

This system has undergone variations in its extension and water volume along several centuries until its desiccation in the first quarter of the 20 th century. By the turn of the 18 th century and beginning of the 19 th the marsh started a disproportionate growth reaching enormous dimensions, thus provoking the loss of farming land and pasture fields. Our interest has been the study of the natural and anthropic causes that occasioned the transformation of this ecosystem. For this, we have resorted to historical documents, ancient maps, descriptions by voyageurs and scientists, complemented by field work in the relicts of the old marsh zone plus the analysis of aerial photographs and satellite images. The phenomenon can be attributed to the wrong watering management in the higher oasis zones, to the topographic characteristic of the terrain and the deficient drainage, jointly with geotectonic phenomena and a period of large snow precipitation in the cordillera that caused the ascent of the phreatic layers.</style></abstract></record></records></xml>
