From opinion to action: Impact of social networks and information policy on private adaptation to floods
Despite efforts to mitigate climate change, adaptation becomes critical. Among climate-induced hazards, flooding is the most costly and widespread, calling for adaptation across scales: from government-led to household-led adaptation. Private adaptation measures, if taken, reduce damages and speed up recovery. Empirical evidence suggests that among socio-behavioral factors, social norms and peer influence are crucial for households’ decisions to …
Characterizing manufactured home parks in North Carolina: A computer vision based approach
This study uses a computer vision-based approach to identify manufactured home parks (MHP) across North Carolina, addressing the critical lack of comprehensive public records for these vulnerable housing communities. Using high-resolution aerial imagery, a custom-trained YOLOv8 object detection model, building footprints, and parcel records, we identified 8460 MHP—more than three times the size of the largest current public dataset. The precision…
Coastal squeeze reduces nitrogen removal services provided by wetlands: Insights from an interdisciplinary framework
Natural landscapes provide valuable ecosystem services that increase community resilience to environmental change. We present a novel interdisciplinary framework to quantify and spatially evaluate the value and fate of coastal wetlands in the context of sea level rise (SLR) and future land use (FLU) plans. We apply our framework in New Bern, NC, USA, where we project changes in nitrogen removal ecosystem services provided by wetlands and undevelo…
Growing Safely or Building Risk: Floodplain Management in North Carolina
Problem, research strategy, and findings Limiting housing and infrastructure in flood-prone places has long been recognized as critical to managing long-term risk. However, due to the difficulty of tracking development at small spatial scales, little empirical research has been conducted to explain differences between communities’ floodplain development patterns. We analyzed new construction across 5 million parcels in the state of North Carolina…
Predicting flood damage probability across the conterminous United States
Floods are the leading cause of natural disaster damages in the United States, with billions of dollars incurred every year in the form of government payouts, property damages, and agricultural losses. The Federal Emergency Management Agency oversees the delineation of floodplains to mitigate damages, but disparities exist between locations designated as high risk and where flood damages occur due to land use and climate changes and incomplete fl…
Disentangling the impacts of human and environmental change on catchment response during Hurricane Harvey
Flooding is a function of hydrologic, climatologic, and land use characteristics. However, the relative contribution of these factors to flood risk over the long-term is uncertain. In response to this knowledge gap, this study quantifies how urbanization and climatological trends influenced flooding in the greater Houston region during Hurricane Harvey. The region—characterized by extreme precipitation events, low topographic relief, and clay-dom…
Attribution of extreme rainfall from Hurricane Harvey, August 2017
During August 25-30, 2017, Hurricane Harvey stalled over Texas and caused extreme precipitation, particularly over Houston and the surrounding area on August 26-28. This resulted in extensive flooding with over 80 fatalities and large economic costs. It was an extremely rare event: the return period of the highest observed three-day precipitation amount, 1043.4 mm 3dy -1 at Baytown, is more than 9000 years (97.5% one-sided confidence interval) an…
