The Development-Risk Paradox in Watershed Urbanism: Structural Barriers to Nature-Based Resilience in Rural Taiwan

Climate change is intensifying risks across interconnected ecological and social systems, yet in many Asian watershed towns, urbanization patterns continue to contradict resilience principles. This study examines the "Development-Risk Paradox"—a phenomenon where intensive development coincides with high environmental hazards—using Wufeng District in the Wu River watershed (Central Taiwan) as an empirical case of a stressed Socio-Ecological System (SES). By integrating literature review, field surveys, and ArcGIS-based spatial analysis (overlaying IPCC AR6 risk metrics, land use data, and housing prices), we investigated the trade-offs between economic expansion and ecological security.

The results reveal three critical dimensions of vulnerability: (1) Spatial Maladaptation: Densely populated settlements significantly overlap with high-hazard zones (flood, landslide, and fault lines), indicating that urban encroachment is expanding into, rather than retreating from, risk areas. (2) Loss of Nature-Based Buffers: The rapid conversion of agricultural land—which traditionally served as a natural buffer—into impervious residential and industrial surfaces has intensified surface runoff and deteriorated air quality (PM2.5), creating cascading ecosystem disservices. (3) Perverse Economic Incentives: Contrary to risk perception theories, property values in high-risk zones have risen due to industrial-driven speculation. This demonstrates a positive correlation between land use intensity and environmental risk. This study contributes to the session by highlighting a critical governance challenge: the prevailing "growth-first" logic acts as a structural barrier to implementing Nature-based Solutions (NbS). We argue that without addressing these underlying socio-economic drivers and land-market dynamics, community-led adaptation and ecological restoration efforts will remain marginalized in the face of developmental pressure.
