About the GCX ICLUS Tool
The Global Climate Explorer (GCX) Integrated Climate and Land-Use Scenarios (ICLUS) Tool was developed to produce spatially explicit projections of population and land-use that are based on the Intergovernmental Panel on Climate Change’s (IPCC) Special Report on Emissions Scenarios (SRES).
Climate and land-use change are major drivers of global environmental change. Impact assessments frequently demonstrate that interactions between climate and land-use change may create serious challenges for aquatic ecosystems, water quality, and air quality. In many cases, it is impossible to assess the impact of climate change without consideration of population dynamics, land-use dynamics, or both.
The Integrated Climate and Land-Use Scenarios (ICLUS) project produced spatially explicit projections of population and land-use that are based on Intergovernmental Panel on Climate Change’s (IPCC) scenarios and pathways.
First, social, economic, and demographic storylines were adapted for the United States. These modified storylines were then used to create population projections that would reflect different assumptions about fertility, mortality, and immigration through the end of this century.
Next, a spatial interaction model was used to simulate the annual movement of people within the United States. Then the results of these population projections are used to calculate the demand for new residential lands.
A geospatial toolset is provided to create and process high-resolution spatial data, and all of the outputs are available.
