Urban residents are often unevenly vulnerable to extreme weather and climate events due to socio-economic factors and insufficient greenspace. This can be amplified if citizens are not meaningfully consulted in the planning and design decisions, with changes to greenspace having detrimental impacts on local communities, e.g., through green gentrification. These deficiencies can be addressed through inclusive landscape-level collaborative planning and design processes, where residents are fully engaged in the co-creation of urban greenspaces. A promising way to support co-creation efforts is gamifying technology-based interactive decision support systems (DSSs). Gamification, the incorporation of video game elements or play into non-game contexts, has previously been used for DSSs in urban planning and to inform the public about the impacts of climate change. However, this has yet to combine informational goals with design-play functionality in the redesign of urban greenspaces. We conducted a review of state-of-the-art video game DSSs used for urban planning engagement and climate education. Here, we propose that gamified DSSs should incorporate educational elements about climate change alongside the interactive and engaging elements of urban planning games, particularly for real-world scenarios. This cross-disciplinary approach can facilitate improved community engagement in greenspace planning, informing design and management strategies to ensure multiple benefits for people and the environment in climate-vulnerable cities.
