Exploring the nexus between urban green space and sustainable tourism: Potential for the green economy

This study explores the nexus between urban green space (UGS) and sustainable tourism (ST) and its potential for achieving a green economy. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) approach was applied to reveal the most relevant documents. This study has identified the 35 most relevant documents from the Scopus database. This study reveals a strong nexus between UGS and ST and a strong linkage between various components of UGS and ST. UGS provides several benefits (economic, social, and environmental benefits) in tourism. UGS also promotes tourism in various aspects like environmental, social, and economic aspects. We argue that tourism has become one of the world's most rapidly rising economic industries that promotes a green economy based on UGS with sustainability. The potential challenges of achieving ST and a green economy are lack of proper planning, GHG emissions, maintaining cultural heritage, and poor information systems and communication.
