Socio-spatial disparities in urban green space resilience to flooding: A 20-year analysis across the southeastern U.S.

This study investigates two decades of green space change across 367 counties in the southeastern United States, integrating FEMA disaster records with multi-period land cover data. Employing generalized additive and logistic regression models, the impacts of flood frequency, development intensity, and socioeconomic drivers were assessed. Flood frequency was identified as the primary determinant of urban green space loss.

The findings reveal a complex trajectory characterized by an initial phase of widespread decline followed by uneven and localized recovery, highlighting the interplay of environmental stressors, urban development intensity, and socio-economic capacity. Recurrent flooding consistently emerged as a dominant correlate of greenspace vulnerability, underscoring the cumulative erosive effects of repeated hydrological disturbances on urban ecosystems. U
