Welcome to the digital home of the Agua Fria Open Space Alliance, Inc. (AFOSA). This platform serves as the primary record of our efforts to support our town and improve community cohesion and quality of life. The image above shows our physical home, the Agua Fria River valley.

Our Mission
AFOSA operates at the intersection of community action and nature. We are interested in programs that strengthen community cohesion and preserve the beautiful landscapes that surround us. From its beginning 20 years ago, the Agua Fria Open Space Alliance, Inc. (AFOSA) aspired to contribute to the quality of life in Dewey-Humboldt. We held public events and studied and wrote about open space. We believe that the world over, improvements must begin with local communities. The social, political, and environmental issues of large cities, states, and nations must be solved from the bottom up, not top down. We believe that Dewey-Humboldt can build a strong reputation and stand out as a leader among Arizona towns.
Leadership and Vision

The Alliance is led by its President, Garry Rogers, a biogeographer whose career has transitioned from faculty positions at UCLA and Columbia University to corporate CEO, and then to the front lines of conservation. Under Dr. Rogers’ stewardship, AFOSA has evolved into a key voice for community cohesion and ecological resilience. Dr. Rogers synthesizes his decades of experience in biogeography and climatology into conservation insights presented in nonfiction books, essays, and award-winning science-fiction novels.

History
Residents of the Agua Fria River basin together with federal, state, and county government representatives conceived and organized the Agua Fria Open Space Alliance (AFOSA) to protect natural open space and the natural surroundings of our communities. The organization’s founders named AFOSA after the Agua Fria River that flows south from Glassford Hill east of Prescott, Arizona, thru Coldwater Farm near the center of the Town of Dewey-Humboldt, and on south to the Gila River west of Phoenix.
