Impact/Purpose:
To estimate the physical and economic impacts of climate change on freshwater fisheries in the United States.
Description:
Using a geographic information system, a spatially explicit modeling framework was developed consisting grid cells organized into 2,099 eight-digit hydrologic unit code (HUC-8) polygons for the coterminous United States. Projected temperature and precipitation changes associated with climate change were obtained for three future greenhouse gas emissions scenarios representing low, moderate, and high emissions in 2030, 2050, and 2100. Water temperatures were projected using regional air/water temperature regressions, and changes in streamflow associated with climate change were estimated using the macro-scale water balance model Climate and Runoff (CLIRUN). The potential economic impacts of projected habitat changes on recreational fishing were estimated by updating a national-scale economic model developed by Vaughan and Russell (Russell and Vaughan 1982; Vaughan and Russell 1982b), which estimated losses in fishing days. Using per day economic values for recreational fishing for different fish guilds derived from the current economics literature, we estimated the total present value of national economic losses to freshwater recreational fishing from 2009 to 2100. This analysis updates, and in some cases improves upon, a previous EPA report: Ecological Impacts From Climate Change: An Economic Analysis of Freshwater Recreational Fishing. U.S. Environmental Protection Agency (EPA-230-R-95-004).
