Three years ago, the city of Medellín adopted a novel approach to manage and conserve biodiversity, launching Colombia’s first local action plan on urban biodiversity: “Medellín, a city of life.” Maria Mejia and Juliana Echeverri argue that this effort should inspire other cities to explore new methods and concepts that link biodiversity to human well-being, resilience, and economic development.

This widespread practice touches on basic service issues like water and energy supply, as well as food provisioning for the city’s most vulnerable residents, explains Ralitsa Hiteva from the Resnexus project.
This April, the second Nexus Conference will focus on the links and trade-offs between water, energy, and food—the “nexus”—in urban areas. Cities are at the forefront of the climate challenge and the heart of the global economy, so they are critical to implementing an integrated approach to meeting the SDGs and building climate resilience.
In the UN Convention of Biological Diversity, 196 nations have agreed to put 17% of the earth’s surface under protection. Author Richard Weller calls for additional land to be protected in the world’s “hotspots”, where biodiversity is threatened by urban sprawl. In his text, he discusses why regional ecology is an issue for urban planning.
With middle classes growing in middle-income countries, the challenge arises how to reconcile increasing consumption with finite resources. Can consumer behaviour be channelled in a way that makes it sustainable? Babette Never reports from a workshop that has explored this question.
How Africa as a continent makes cities work for all while realising a low carbon and climate resilient economy, will determine the success of the Paris Agreement, says Sadiq Okoh. In his article, he outlines possible paths to green development.
