Founded in 2005, the On Sustainability Research Network is brought together by a common concern for sustainability from a holistic perspective, where environmental, cultural, economic, and social interests intersect. We seek to build an epistemic community where we can make linkages across disciplinary, geographic, and cultural boundaries.

The Twenty-first International Conference on Environmental, Cultural, Economic & Social Sustainability features research addressing the following annual themes and special focus:

• 2025 Special Focus—Sustainable Development for a Dynamic Planet: Lessons, Priorities, and Solutions
• Theme 1: Ecological Realities
• Theme 2: Participator Process
• Theme 3: Economic, Social and Cultural Context
• Theme 4: Education, Assessment, and Policy
