  • Over the past few decades, access to abundant and easily available fossil sources aided in remarkable advancements in technologies and rapid urbanization. The unparalleled growth in population and migration of rural residents to the urban areas have transformed cities to hotspots for major anthropogenic activities, seminal contact points between natural and socio-economic activities, and areas responsible for generation of more than 80% of gross domestic product (GDP). This has placed cities at a crossroad of facing environmental grand challenges posed by population expansion, climate change, and depleting resources. Ushered by these problems, cities are directing the course of waste utilization towards sustainable production and consumption strategies by adopting the principles of circular economy (CE). This organic waste generated in huge quantities can be considered as a valuable resource in the urban biocycles. The present article highlights the importance of looping back this biogenic organic waste (domestic) to a certain extent in a decentralized way. It offers an eco-centric view to adopt circular urban food practices by constructing and operating a keyhole garden (KHG) as a case study. This approach works in synergy with nature and adopts the principles of biomimicry and cradle to cradle, wherein waste is reintroduced into the system as input resources or is metamorphosed to valuable materials. It underlines the role of CE approaches to spark this transformation and strategically direct the flow of valuable domestic waste resources to close the urban nutrient loops in a decentralized and regenerative approach. While the solutions to close the loop and recycle wastes address the end of pipe problems, the community-based innovation strategies aim at building resilience, producing food more locally, limiting the use of fertilizers, conserving water, and also combating climate change.
