This document introduces the concept of place-based creative problem-solving as an approach to participation and social innovation. It argues that innovation should be defined more broadly than just business ventures, and should include grassroots efforts by citizens and communities. Everyday experiences have the power to shape understandings of urban sustainability. The examples highlighted demonstrate how creativity and collaboration can generate solutions to social and environmental issues. The goal is to document initiatives that push boundaries of participation and governance, and prove how impactful everyday actions can be in building more livable, inclusive, and resilient cities.
