Background and objective: Globally, the sustainability of urban areas is being compromised due to indiscriminate urbandevelopment, making the creation and management of green spaces increasingly critical. Green spaces play a pivotal rolein connecting degraded natural ecosystems, and the concept of Green Infrastructure is gaining prominence as a strategyfor managing green networks. A Green Infrastructure (GI) is a network of interconnected green spaces that provide benefitsto humans through their utilization and management, fulfilling environmental, social, and economic functions. However,in most urban areas, green spaces lack connectivity between each other and are not managed in an integrated manner. Additionally, the types and functions of green spaces defined by policies and regulations vary, making it challenging toimplement GI. Therefore, this study aims to examine and reclassify precursor indicators in order to effectively apply GI tourban strategies. It seeks to discuss management approaches based on GI, with the aim of facilitating its implementation. Methods: The city of Liverpool in the UK has presented a multifunctionality strategy for GI, which has been utilized as aglobal exemplary case. This study adopts the multifunctionality GI strategy proposed by the city of Liverpool, andreclassifies the types and functions of GI. It selects indicators through Focus Group Interviews(FGI) with GI experts andfield surveys. The selected indicators of GI were utilized in a survey for evaluation of multifunctionality. The quantitativedata collected through the survey were mapped using overlay techniques, in which led to the deriving a multifunctionalitymap of GI. In the process of mapping, weights derived from Analytic Hierarchy Process (AHP) analysis were applied toenhance the reliability of the quantitative data from the survey. Results: In this study, suitable indicators for GI in the study area were selected, and the functionality of each land cover (LC)type was evaluated. As a result, the study area was found to provide multifunctionality within a single land parcel. Thehighest-scoring LC type is Woodland, and the predominant functional category is Human-Wildlife Coexistence. Thelowest-scoring LC type is Cemetery, with the least represented functional category being Timber Production. Conclusion: GI fulfills multiple functions that provide a range of benefits to humans (multifunctionality). To maximize suchmultifunctionality, it is crucial to manage scores for each functional category according to LC type. GI is not solely focusedon specific functions, but also requires strategies to enhance functionalities lacking in LC types with low multifunctionalityscores. The GI indicators proposed in this study and the GI multifunctionality assessment can serve as essential data forreview when local authorities are formulating spatial plans related to urban areas, green spaces, forests, and other relevantareas.
