Sustainability of the Expansion Areas for Coastal Touristic Sites “E.A.C.T.S” Such as the case of El-Aouana in Algeria: Indicators for considering biodiversity

There are many forms of tourism that can be described as "viable" industries, but fail to take into account biodiversity when studying the planning of sites. All these forms of tourism seek to achieve sustainability differently but all agree for the need to minimize the negative impacts of human activities on the environment. However, they consume more non-renewable resource for the search of comfort to satisfy customers who become more and more demanding and sensitive to the ecology of the visited places. Coastal biodiversity offers inestimable wealth in terms of flora and fauna but this diversity is threatened by human activities that attack it directly by soil erosion, overfishing and pollution. Various methods for evaluating sustainability of urban planning instruments and touristic sights are applied throughout the world with different names and impact studies on the environment. Our purpose here is to explore the research works done in this subject and implement the role of biodiversity in the tourism and hotels and to verify which indicators could be adopted for taking into account the biodiversity in the studies of the Expansion Area and Touristic Coastal Sites (E.A.C.T.S) such as El-Aouana town situated in the west of Jijel city, Algeria.
