Title: A Southern Arizona Dark-Sky Update: Trends, Challenges and Opportunities

Tucson has long billed itself as the “world capital of astronomy,” and it is the origin point of the global dark-skies movement. Proactive efforts in public policy and lighting design practice have slowed the increase of regional nighttime light emissions relative to other parts of the Southwest, but population growth and economic development concerns put upward pressure on demand for artificial light at night (ALAN). Local dark-sky advocacy efforts aim to counter this trend with actionable goals for reducing ALAN consumption while enhancing nighttime community safety, security, and amenity. In this talk, John will review the state of affairs involving light pollution in the area and the efforts of DarkSky Southern Arizona to pursue effective solutions during the first three-year strategic planning term since the group’s organizational 2023 reboot. In addition, John will describe the trends and opportunities that can strengthen our region’s leadership on outdoor lighting issues.
