Future Land Cover Scenarios
DRB2100 Version 3.1 builds on DRB2070 Version 2, representing revised alternative forecasts of urban land cover in the Delaware River Basin (DRB) out to 2100. Version 3.1 includes the “Corridors” and “Centers” scenarios and also adds another two scenarios, considering “Non-Protection” scenarios for both urban growth scenarios. These “Non-Protection” scenarios consider the “what if” scenario: “what if land protections were to be entirely removed?” These scenarios allow us to envision what the future landscape would look like without protected areas, highlighting the potential value of our existing protected lands network.

Our collaborators at the USGS modeled land cover to 2070 using the Chesapeake Bay Land Change Model. A comparison of these two products will soon be available to review. In the long term, we hope that our data can be integrated into the Stream Reach Assessment Tool.
Let us know how you anticipate using our mapping and modeling tools!
