Integrated Climate and Land Use Scenarios (ICLUS)
Project Overview
The EPA Global Change Research Program's Integrated Climate and Land Use Scenarios (ICLUS) project is developing scenarios broadly consistent with global-scale, peer-reviewed storylines of population growth and economic development, which are used by climate change modelers to develop projections of future climate.
Climate change and land-use change are global drivers of environmental change. Impact assessments frequently show that interactions between climate and land-use changes can create serious challenges for aquatic ecosystems, water quality, and air quality. In many cases, it is impossible to determine the impact of climate change without consideration of land use and land cover dynamics.

Downloads
1. Refer to the EPA Land Use Scenarios Final Report and download the ICLUS v1.3 datasets or check out the ICLUS+ Web viewer
2. The ICLUS tools for ArcGIS will allow users to:
- Customize housing density patterns by altering household size and travel time assumptions.
- Reclassify housing density into classes different than those already provided.
- Generate a map of estimated impervious surface based on a housing density map
