Environmental risks or costs? Exploring flooding and the urban heat Island effect in planning for policymaking: A case study in the Southern Taiwan Science Park

This study examined a specific case of planning for policymaking in response to two physical environmental issues: flooding and the urban heat island effect (UHI). The Southern Taiwan Science Park (STSP) was selected as a case study. Data were primarily collected through interviews as well as through policy review. The assessment showed significant differences in policymaking when comparing these two issues. The issue of flooding was considered and managed well. The UHI, however, was poorly considered or ignored altogether in policymaking, even though it has shown an increasing trend over the last decades, to a greater degree in the STSP than in the city centre. The results implied that the neoliberal approach to planning of decision-making performed better in managing risks (i.e., flooding and relevant disasters which had occurred in the past) than costs (i.e., the UHI and the future threats resulting from development). The STSP's spatial development strategy, underpinned by the neoliberal approach with an agenda for maximising economic growth, was questionable for environmental management toward resilience.
