Water is a vital resource for humans, but there is a lack of understanding about its value. The tourism industry will need more water because there are more tourists, hotel standards are getting better, and there are more water-intensive tourist activities. Climate change is also anticipated to affect the water supply. This study aims to investigate the role of the tourism sector in water resource depletion in Azerbaijan, a country facing water scarcity, and recommend actions for the hotel industry. This research employed a comprehensive analysis of published articles in high-ranked journals to investigate the impact of tourism on water resource depletion in Azerbaijan. The study also analyzed the current state of water resources in the country and identified the major factors contributing to their depletion. The study found that the tourism industry in Azerbaijan significantly contributes to the depletion of water resources through increased water consumption and wastewater production. The analysis also revealed that the major factors affecting water resources in the country include increasing urbanization and global warming. The study recommends that the hotel industry take action to reduce their water consumption and wastewater production to mitigate the impact of tourism on water resources. Additionally, the study proposes that policymakers should prioritize sustainable water resource management practices to ensure the availability of water resources for future generations.
