Ecosystemic urbanism: a tool to make more sustainable cities

Barcelona Metròpolis

The competitive dynamics of thousands of cities around the world, consuming resources without limit, is unsustainable and exceeds the capacity of some essential variables of ecosystems to ensure the survival of the planet.


The city is the most complex ecosystem created by the human species. It is at the same time the system that produces more impact on the natural ecosystems, because it contains most of the Earth’s population and consumes around 70 % of the energy. Cities compete with other territories. The competitive scale depends on its size and its features. Barcelona, for example, competes in the international arena to attract investments, activities in the field of knowledge and resources of all kinds.


The problem is that the strategy used so far to compete is based on the increase in the consumption of resources. This additive strategy results in more soil consumption, of materials and of energy that, at the same time, means an increase in the consumption of natural resources and a greater negative impact on local and global ecosystems on the planet, for example, in the form of greenhouse gases (global impact) or in the form of emissions of pollutant gases and particulates (local impact) which in the metropolitan area of Barcelona (56 municipalities including the capital) cause the premature death of about 3000 people a year.
