In an age of planetary transformation, ecological concerns have risen to the top of our priorities. The complex entanglements between humanity and the Earth are today at the centre of discussions in scientific, political and economic fields. The awareness that humankind (or part of it) has had a geological impact – see the discussion about the terms anthropocene, capitalocene, chthulucene, etc. – has further increased these concerns. Demonstrating how the ‘Earth System’ has been heavily affected by human actions has made evident the need to critically rethink modes of inhabiting the Earth. These are issues that both directly and indirectly affect architecture. Directly, due to its large degree of responsibility in these matters: endless expansion of urbanization has been key to groundwater depletion, soil degradation and air pollution. Indirectly, as its object of study – living and modes of co-existence – is facing dramatic transformations: pollution, changes in land-use, water scarcity or climate change are imposing drastic reconfigurations in modes of living. In the face of these developments, ecology has assumed vital importance for architects and design practitioners at large.
