From grey to green: rethinking urban in-between spaces through rooftop agriculture and climate design

Urban in-between spaces, often overlooked in conventional planning, present untapped opportunities to address climate change through spatial reactivation. This paper explores the potential of rooftop agriculture as a climate-responsive strategy to convert residual urban surfaces into productive green infrastructures. Grounded in the concepts of climate-sensitive design and nature-based solutions, the study discusses how rooftops can contribute to urban decarbonization. By examining the ecological, social, and spatial dimensions of rooftop agriculture, the research proposes a reconfiguration of urban metabolism based on multi-functional land use. The aim is to offer a contribution that integrates architecture, agriculture, and climate resilience, transforming the urban fabric from grey to green. The paper contributes to the discussion on climate-neutral cities by highlighting the strategic role of inbetween spaces in sustainable urban transformation.
