Circular Regenerative Cities: A Look at the Systemic Changes in the Human-Nature Relationship
Cities are projected to house 66.3% of the world’s 9.5 billion inhabitants by 2050. By then, it is expected that they will generate 70% more waste – from 2.01 billion tonnes to 3.4 billion tonnes. That, coupe with the fact that cities are responsible for 75% of CO2 emissions, indicates that it may be the time to look beyond sustainability. Regenerative cities is a relatively new concept that was first introduced in 2010 by the World Future Council. The main emphasis lies on cities’ role to both sustain and regenerate natural resources being consumed and wasted. The regenerative city concept aspires to adopt a circular rather than linear model of resource conception, by shifting to local and renewable energy resources. In other words, a regenerative city model’s ecosystem is maintained when an organism’s output is an input for another. This model is basically referred to as the circular economy system. For a circular economy to succeed, regenerative cities should have a symbiotic link with their local hinterland, i.e. agropolis. Cairo, for example, is a typical Petropolis, meaning that all its key functions – production, consumption and transport – are powered by massive injections of non-renewable energy. This significant link between urban areas and their rural territories is the core of the regenerative vision. It improves the health of the ecosystem by reusing waste as a source of value.
