This chapter investigates community engagement and participatory design as pivotal in forging climate-resilient urban strategies. These approaches involve local communities in the design process, fostering ownership, knowledge enhancement, and social cohesion for sustainable urban resilience. Key concepts of community engagement and participatory design are examined, emphasizing their significance in climate resilience. The chapter outlines integration methods into urban design, such as workshops and collaborative platforms, and the empowerment of communities to input into climate-resilient spaces. Worldwide case studies illustrate the benefits of these approaches, including heightened climate risk awareness, vulnerability identification, social equity, and tailored solutions. Challenges like inclusivity, interest conflicts, and technical-community balance are also discussed. The chapter concludes with guiding principles for practitioners and policymakers to enhance community engagement and participatory design effectiveness, advocating for trust, capacity building, perspective integration, and enduring community-designer-policy partnerships. Embracing these methods, cities can leverage collective wisdom for more sustainable, inclusive, and resilient urban environments against climate change.
