PROJECTED VARIATION IN URBAN STREAM LENGTH BASED ON CLIMATE AND LAND USE SCENARIOS
The impact of the projected urbanization for US cities in the 21st century on freshwater ecosystems is dependent on urban management and design decisions over the next 100 years. Integrated Climate and Land Use Scenarios (ICLUS) provide projections of a range of potential patterns of future urban development based on storylines of population growth and economic development and correspond to the Intergovernmental Panel on Climate Change’s future climate projections. We used existing ICLUS projections to quantify urban stream length and impairment across two scenarios of urbanization for the southeastern US (South Atlantic Gulf watershed), an area both rich in biodiversity and home to multiple rapidly expanding metropolitan areas (Atlanta-Charlotte mega-region). We compared these projections for 2100 to baseline conditions to estimate potential change in urban stream length across these scenarios at the local sub-watershed level (Hydrologic Unit Code 12). Our work reveals low and high thresholds of urbanization and demonstrates the extreme variation of urban impacts on streams both in terms of scale and the role of land management.
