Zanzibar has witnessed fast growth in tourism due to its natural beauty and unique cultural values. On average, about 600,000 tourists arrive annually, creating demand for more hotels, which significantly adds to the generation of waste streams on the island. Food waste is a multifaceted issue and a cross-sectoral problem. However, existing research on food waste management in hospitality focuses mainly on operational and managerial perspectives, while overlooking the role of stakeholder engagement and their social interactions, creating a gap in understanding the relational and context-specific factors shaping sustainable practices, particularly in small island destinations. Therefore, collaborative efforts from different stakeholders are required to ensure sustainable waste management. This study aims to map the key stakeholders and analyze engagement dynamics and structural patterns of social networks to improve hotel food waste management as part of a sustainable tourism strategy in Zanzibar. Stakeholder mapping and analysis, and social network analysis, were applied to examine both the dynamic and interaction patterns. Semi-structured interviews were conducted with different stakeholders related to tourism and waste management operations to solicit their roles, responsibilities, interests, knowledge, interaction, information sharing, influence, and power in decision-making. The results revealed that waste management is the responsibility of local authorities, and there was limited interaction, information sharing, and coordination among stakeholders and across sectors. Building collaborative relationships is important and can be achieved by stimulating interactions through active communication platforms, including social media and online webinar sessions. Moreover, the study proposes a context-specific model for analyzing small-scale stakeholder interactions regarding food waste management in tourist hotels that can inform future stakeholder coordination and policy interventions.

Tourism is the key economic sector of and contributor to employment in Zanzibar. However, tourism growth creates a demand for more hotels, contributing to more waste. Meanwhile, food waste in the hospitality sector remains a concern due to its impact on food sustainability and its economic and environmental footprint. This study examines food waste management in selected tourist hotels located along the east coast and north districts of the island and recommends strategies for improvement. Mixed methods, including surveys and key informants’ interviews and observations, were used for data collection to map the waste flow along the food value chain, analyze the selected hotels’ management practices, and consider stakeholders’ perspectives. The findings reveal that food wastage occurs at each stage of business operations, and the largest waste stream is located at hotels, with an average estimate of 1.8 kg per guest per day. Most waste is generated during food preparation and when serving customers, constituting both avoidable and unavoidable food fractions. Moreover, the implementation of sustainable practices is scarce due to challenges, such as a lack of food waste minimization and management plans and a low level of knowledge and coordination among staff and other stakeholders. However, hotel managers’ knowledge, experience, and willingness to change, as well as the ongoing Greener Zanzibar Campaign, are driving forces for enhancing circular and sustainable practices at tourist hotels. Based on the findings, strategies, such as involving local suppliers close to the hotels for perishable products, reusing leftover food for staff and donations to local communities, and staff training on handling food waste are recommended. The practical implications of this study will help hoteliers reduce food wastage and contribute to more sustainable tourism development in Zanzibar.
