The environmental and social challenges have a direct impact and pose a significant obstacle to the sustainability of tourism development. Decision-makers face challenges that can be supported and guided by strategic environmental assessment (SEA). This can be achieved by implementing various mechanisms and policies based on spatial and temporal environmental analysis and assessment to mitigate expected negative effects and risks. The research methodology clarifies key concepts such as sustainable tourism development and strategic environmental assessment, and demonstrates how theoretical and analytical thinking is reflected in the research outcomes. These outcomes include identifying the stages of strategic environmental assessment and its contribution to managing the surrounding environment in tourist areas. Finally, the research findings highlight how to achieve sustainable tourism development in light of the proposed policies and strategies, utilizing SEA mechanisms to address environmental and social challenges through systematic stages aimed at finding alternative solutions for tourism development. This is done based on environmental analysis, assessment, and stakeholder participation in tourism development areas (e.g., Marina El Alamein Center).
