Sustainable technologies are not only critical to our future, but are making for a better present in the Colombian city of Medellin.

For proof, you don’t have to look any further than the transformation of El Morro de Moravia, a rubbish dump neighbourhood once declared a “public disaster,” into an urban park with an ecomuseum and science-technology centre.

The transformation has also provided a technology testing ground for researchers at the UNESCO Chair of Sustainability at Barcelona’s Universitat Politècnica de Catalunya (UPC). For example, the site has enabled researchers to try out the combination of natural treatment technologies such as constructed wetlands, and buffer strips, which are strips of vegetation that absorb and help degrade pollutants.
