There is historical evidence indicating migration has been a traditional response of Sahrawi societies to the changing challenges of environmental conditions, especially the climatic shift and severe periods of droughts. The disintegration of traditional society, together with modernization, the introduction of agriculture, and sedentarization, the process of urbanization and the implementation of new strict political borders that fractured the once open space they used to move within, modified dramatically the previous patterns of climatic periodic migrations. Although we have not been able to establish a clear link between environmental conditions and migration within Moroccan controlled Western Sahara, on the contrary the environment seems to play a crucial role in determining the rhythm and other features of the migratory flows abroad from the refugee camps on the Polisario ruled part of Western Sahara and Tindouf.
La conservación de los paisajes culturales modelados por actividades agrarias tradicionales es objeto de una creciente atención con el fin de evitar su degradación. Entre los paisajes culturales a conservar se encuentran paisajes silvopastoriles creados por el pastoreo estacional basado en la trasterminancia y la trashumancia y por actividades forestales tradicionales. En este artículo se analizan los excepcionales valores del paisaje de las Sierras de Urbasa y Andía, que lo hacen potencialmente susceptible de ser inscrito como paisaje cultural en la Lista del Patrimonio Mundial de UNESCO. Asimismo, se examina la gestión que llevan a cabo los órganos de gobierno que administran el territorio concernido. Por último, se identifican problemas y oportunidades para garantizar la conservación del paisaje cultural.
