The hotel industry in Iran faces critical challenges that underscore the urgent need for sustainable practices, specifically in the realms of energy, water, and food. Despite industry growth, a mere three percent of hotels fall into the five- and four-star categories, emphasizing the need for widespread adoption of sustainable practices. Focused on Ramsar in Mazandaran, the study underscores the importance of eco-friendly strategies to tackle challenges related to the food–water–energy nexus. Employing the SCOC, Fuzzy BWM, and Z-MARCOS methods, the research proposes a robust framework for evaluating hotel development strategies. The case study reveals a concentration of hotels in Khorasan Razavi, Mazandaran, and Tehran, urging prioritization of sustainable practices in these regions. Analyzing Ramsar’s climate, the study suggests leveraging solar energy and implementing green roofs, emphasizing an integrated approach to achieve eco-friendly hotel construction. Furthermore, the research provides a prioritized set of strategies based on SCOC, aligning with criteria regarding the water–energy–food nexus. It emphasizes internal strengths, opportunities, and strategic technology partnerships while acknowledging external challenges such as political stability and climate change risks. The discussion introduces an Importance–Performance Analysis (IPA) to guide managerial decisions, presenting an insightful perspective for effective strategy implementation in Iran’s evolving hotel industry.

Solid waste management has been known to play an important role in public health and the environmental status of developing countries. Waste assessment can help researchers and governors in management programs and devising alternative plans in order to improve public health and economical savings. In the present study, statistical estimations regarding waste generation and type of solid wastes in central provinces of Iran has been provided. Chaharmahal and Bakhtiari and Yazd are located in central regions of Iran, with an average waste production estimated at 0.507 and 0.293 kg/ca/day, respectively. Improper solid waste management continues to be a big concern in the region, with water contamination as its main consequence. High amount of putrescible material ratio showed the capability of bio-fuel generation in rural areas. The results of survey conducted among waste management experts showed that waste separation prior to collection is recommended as the most efficient method for managing waste collection in the area. This study could contribute to the body of knowledge enhancement by proposing a set of practical waste management strategies that would be beneficial in rural areas.
