The research analyzes the current state of tourism investments and evaluates their impacts on the economic, social, and environmental levels. A descriptive-analytical methodology was adopted, covering both the theoretical and legal frameworks of tourism investment and sustainable development, with particular focus on Investment Law No. 22-18, which was introduced to improve the investment climate by facilitating procedures and offering incentives to investors. However, the practical implementation of this law still faces several challenges, including weak coordination among public stakeholders and insufficient training in the tourism sector, further complicating the investment environment in this vital field. The study also analyzed statistics related to various tourism projects, revealing a clear gap between the available tourism potential and the actual volume of investments. It concludes by recommending the development of a comprehensive strategy to enhance tourism investment through legislative reforms, administrative simplification, and improvement of the business environment to ensure inclusive and sustainable tourism development.
