Future scenarios: A technical document supporting the USDA Forest Service 2020 RPA Assessment
The Forest and Rangeland Renewable Resources Planning Act of 1974 (RPA) mandates a periodic assessment of the conditions and trends of the Nation’s renewable resources on forests and rangelands. The 2020 RPA Assessment will evaluate the future of the Nation’s renewable natural resources through 2070. This publication describes the process used to select a set of four integrated scenarios to represent a plausible span of socioeconomic and climate futures that underpin the natural resource analyses. These four scenarios, and their associated assumptions about population change, economic growth, and climate change, are also described in this document.
