Ecocities are concerned with the long-term health of people and Earth’s ecosystems upon which all life depends. “An ecosystem is a biological environment consisting of all the organisms living in a particular area, as well as all the nonliving physical components of the environment with which the organisms interact, such as air, soil, water, and sunlight” (Ecocity Builders).
Because ecocities take responsibility for stewarding the natural resources on which they depend, wherever in the world those resources are situated, they participate in “inter-regional ecology” (Kissinger and Rees, 2010; Kissinger et al., 2011). This means that ecocities are concerned with regenerative processes in and around the city AND in the areas from which the city draws sustenance and to which it releases wastes that are ultimately assimilated by natural processes including carbon sequestration and water purification. For this reason, the description of an ecocity includes the intention of residents to participate in ecologically supportive lifestyles that respect planetary boundaries. This includes supporting sustainable forestry management, building soil health, and protecting clean water supplies all around the world, not just within the geographic boundary of the city.
Thinking about the city within the context of its urban ecosystem, meaning the entire system of biological relationships wherever in the world they are located, that are involved in sustaining the city and its inhabitants, is a hallmark of ecocity thinking.
