Bustling streets, tons of creative energy and the promise of new opportunities. Large cities have always drawn people like magnets. The world’s modern metropolises still lure with the promise of excitement and possibility. Yet, mega cities also represent one of the biggest challenges for sustainable urban development.
According to projections by the United Nations, 68% of the world’s population will live in cities by 2050. While cities only take up 2% of the world’s surface, they consume 78% of the world’s energy. What’s more, they produce 60% of the world’s greenhouse gas emissions. That’s why any serious attempts to reverse climate change will need to include a framework for sustainable urban development.
Gregor Mews is an urban planner and the founder of the Urban Synergies Group. After having studied urban planning and design in Berlin, he travelled the world to learn more about human life at different stages of urban development.
Now based in Australia, Gregor is working with local governments, NGOs, businesses and UN Habitat to create healthier, more connected and sustainable urban communities. In short, if you want to have a philosophical discussion about what the future of the city should look like, Gregor is your man!
“We’re at a historical moment in time”, says Gregor about the urgency of the problem. “We have three years to turn the trend in global warming around until we enter the adaptation phase.“ However, to tackle this problem, it would require more than just installing solar panels on rooftops.
It’s in this context that Gregor identifies 3 fundamental shifts required in our thinking that will ultimately lead to sustainable urban development.
1. Putting human needs at the heart of sustainable urban development
Most people will have heard about the Mercer Global Liveability Index that ranks cities based on the quality of life they offer to their citizens.
“The issue with this ranking system is that it’s basically designed for rich minorities. It caters toward highly educated people with a high socio-economic status. However, these rankings tell us very little about what ordinary life looks like for the majority”, says Gregor. “For example, Sydney has often been ranked as one of the most liveable cities in the world. But I doubt that most people in Western Sydney would agree with this assessment.”
