Our current cities are highly dependent on their hinterlands or other cities for their essential resources. Moreover, accelerating urbanization, increasing scarcity of resources and climate change force us to re-think and redesign urban systems. A paradigm shift towards sustainable consumption is needed. Moreover, there are many unexplored potentials to minimize impacts and maximize reuse and recovery of resources within urban areas. Urban Harvest Approach (UHA) is a holistic approach, based on the urban metabolism concept. UHA aims for better urban resource management by harvesting urban resources. UHA works on the principle that urban systems can achieve sustainable consumption by strategically managing resources: minimizing demand, minimizing outputs and multi-sourcing. UHA focuses on studying urban cycles and technology implementation based on local context to improve resources cycles within urban areas. UHA strives for integrating urban resource management as a key element for urban planning to optimize linkages and synergies among different flows and temporal and spatial scales. The urban harvest approach has been used to evaluate the urban water metabolism of an average household in the Netherlands. The different strategies were tested and the results show reductions of 52% for input water and 78% of output wastewater by following the UHA. Furthermore, water cycles at block level were developed to understand the relationships between scales and proposed improvements towards self-sufficiency by implementing decentralize technologies. Cases with semi-arid climates are being developed to validate the methodology |
