Thessaloniki has a dense urban structure with limited open and green spaces. As a coastal city severely impacted by climate change, it faces multiple interconnected challenges, including extreme weather events, flooding, and peri-urban forest fires. These issues are further compounded by the city's aging infrastructure and deteriorating buildings, increasing its vulnerability (Ref 1). Kipos 3, a community garden, is part of the "Green Neighborhoods" project proposed in the Thessaloniki 2030 municipal resilience strategy (ibid.). Established in 2015 on a 600-square-meter plot donated by the municipality, the garden is now managed by 30 local families under the continued stewardship of the Municipality (Ref 2, 3). The garden's creation was supported by a team of architects, landscape architects, and agriculturists, and features a variety of herbs and edible plants grown using permaculture methods (Ref 3). The garden hosts a greenhouse along a range of environmental, recreational, and educational activities, providing an opportunity to foster a more cohesive, inclusive, and resilient community. It also serves as a space for synergies and discussions about the future of the city (Ref 3, 4). Recognized as a good practice, the intervention has been showcased in national, European, and international networks (Ref 2, 4).
