Protected desert areas present two challenges: economic necessities and environmental constraints. At first glance, these two challenges seem irreconcilable, given the many (primarily anthropogenic) pressures, such as overexploitation of natural resources and excessive abstraction, that exacerbate the current ecological impacts. So, the new strategy of tourism governance in Algeria is based on a virtuous logic between the preservation of biodiversity and the commercial interests of protected areas. Saharan parks are now moving toward a prospective vision of growth based on ecotourism. This approach supports an active program of socioeconomic development, which has been undertaken in the two most emblematic cultural parks in southern Algeria: Ahaggar and Tassili n’Ajjer—which was placed on the UNESCO World Heritage List in 1982 and listed as a biosphere reserve in 1986. This approach unites all the inhabitants of the parks around a common heritage to be valued and protected. In short, it seeks to propose an ecodevelopment policy in which the Tassili-Ahaggar parks would become a model to be replicated. It aims to support ecotourism in all protected areas of the Algerian Sahara in order to create a network of destinations focused on alternative tourism, attractive for domestic and international tourists alike.
