The Human Dimensions Program of the Rocky Mountain Research Station provides social and economic science based innovation to human societies as they develop a sustainable relationship with their environment. Major issues confronting societies across the globe such as global climate change, energy, fire, water, and ecosystem services all have important social-economic dimensions that will be explored and addressed by this program. The national RPA scientists are in this program. RPA will be expanded and work closely with the Inventory, Monitoring and Analysis Program to provide a robust, Regional (interior west), dynamic knowledge base. Expertise residing in the program includes market and non-market economics; collaborative planning and community involvement; decision science and operations research; and risk management and organizational development. This program will work closely with the Fire, Fuel and Smoke Program and the Wildland Fire Management RD&A to improve firefighter and public safety, reduce large fire costs, expand the wildland fire use program, and expand the treatment of hazardous fuels for watershed restoration that is strategic, cost-effective, and socially acceptable.
