Policymaking and developments towards governance in green infrastructure design: the case of Taipei city

Green infrastructure (GI) has emerged as a key component in urban resilience strategies for integrating ecological and social benefits. Initially driven by government bodies, GI initiatives have expanded to include different groups of participants in co-production and co-implementation. This study proposes that Taipei's GI governance is determined by formal and informal regulations and connected with other discourses. The policy arrangement approach (PAA) is therefore used to study actor roles, discourses' effects on institutional arrangements, and GI planning issues. By assessing existing strategies and interactions among key actors, the study identifies how shifts in community participation and government authority shape GI design and functionality. The use of PAA in Taipei also offers valuable insights for global cities engaged in similar initiatives and challenges encountered in GI delivery. Findings demonstrate that participatory and collaborative approaches to governance of open spaces and greenspace are aggressively promoted and support communities in developing stewardship capabilities, but also that these alone are unlikely to be transformative without alternative funding mechanisms in the future. Overall, the participatory approach emphasises transparency and accountability for residents, however, new financial schemes are required to carry on GI design and management in the long term.
