The San Pedro River Basin Data Browser provides environmental protection managers and practitioners with an ability access spatial data for the entire San Pedro River Basin (U.S./Mexico). It includes data from the Integrated Climate and Land-Use Scenarios (ICLUS) database. Using ICLUS, future growth within the San Pedro River Basin is represented by housing density maps generated in decadal intervals from 2010 to 2100 using ICLUS future housing density maps adapted from the Intergovernmental Panel on Climate Change (IPCC) Special Report on Emissions Scenarios (SRES) social, economic, and demographic storylines to the conterminous United States.
The supporting report (EPA/600/R-12/550) for the new data browser is attached and dates back to mid-2012. The actual data base (EPA/600/C-14/047) was peer-reviewed and reconciled late last year and moved through official peer review process last month. It has been posted to the New Mexico State University site at: http://fws-case-12.nmsu.edu/SanPedro/
The difference between the new and existing data browser is that the new database covers the entire river basin for digital land cover data and other ancillary datasets, not just the upper watershed plus it includes the EPA Integrated Climate and Land Use Scenario (ICLUS v 1.3) datasets. The ICLUS datasets are in ESRI Grid format (100 m resolution) and project housing densities from the year 2010 to the year 2100 in ten-year increments based on five climate change scenarios: A1, B1, A2, B2 and BC. The five scenarios represent different Intergovernmental Panel on Climate Change (IPCC 2001) emission storylines related to population growth and economic strategy for the U.S. [PDF]
The Upper San Pedro River is an EPA Office of Research and Development geographical initiative dating back to the mid-1990s that was designed to evaluate landscape change over time and develop a system of landscape and hydrological indicators, data, or models that can be used by decision-makers relative to natural resource management.
The San Pedro Geo-Data Browser is a complete GIS database for the entire Upper San Pedro Watershed (U.S./Mexico); it provides contemporary spatial data to public resource managers, non-governmental organizations, decision-makers, researchers, and user groups.
