Being aware of the importance of reconsidering the touristic activity and according to the definition of the notion of sustainable development, Moroccan public authorities have set up since the year 2000 some sectoral strategies to adapt the tourist supply in accordance with the new requirements of the tourists. The emergence of this variety of tourism offers (rural, solidary, ethical, Community…) certifies the vivacity of a phenomenon in full development. These new offers have a common denominator: it is to combine the environmental protection and the economic profitability in a long run. What is the context in which this responsible, solidary touristic activity has emerged? What is, then, the commitment of morocco in this new touristic offer? What are the efforts of certain associations for contributing to the territorial development? To answer these questions of research, we will, first, present a review of the literature about the evolution of mass tourism to durable tourism. Secondly, we will treat the importance of solidary tourism to valorize the specific resources of the territory in order to sit a territorial development.
