注释,注释: The development of sustainable tourism has become a growing trend in multi-level projects in developing countries aimed at supporting the economy and preserving the ecosystem. Despite the fact that Algeria is considered one of the richest and most diverse countries in Africa, the development of tourism on its 1200 km coastline faces many problems and difficulties. One of these obstacles is the lack of a comprehensive strategy that guarantees the development of the tourism sector. In recent years, the economic importance of tourism has grown significantly. However, the tourism industry without a properly planned strategy, as in the case of Algeria, cannot provide the expected economic growth. The purpose of this article is a theoretical review of various strategies for sustainable development through the development of various tourist facilities on the Algerian coast, as well as an assessment of the selected strategies for the development of tourism in Algeria in terms of urban infrastructure, ecosystems, the growth of the number and quality of architectural structures. Methodologically, this study analyzes various strategies of sustainable tourism development applied in the world. The study examines tourism development strategies and the role of designing various types of tourist facilities and resorts for the development of this industry in the coastal areas of Algeria, taking into account the conservation of natural resources and biodiversity.
