For my final year project I’m investigating what measures are and can be employed in cities to maintain biodiversity. I was recently allocated this and luck would have it, that two days later I get an email saying that Herbert Girardet was coming to Imperial to talk about regenerative cities.
Girardet has worked in urban development for many years and is the co-founder of the World Future Council. He has released numerous books including “Creating Sustainable Cities” and “Cities People Planet“. He has also directed more than 50 documentaries, working all over the world. All of this and his receipt of the UN Global 500 Award for outstanding achievements in environmental science suggest just how much influence this man has had in the field of sustainable cities over the years.
So as you can imagine, I was pretty excited about going to this talk and therefore, managed to arrive far too early and ended up sat alone in the lecture theater for about 15 minutes before anyone else trickled in.
Girardet was a great speaker and he oozed with the confidence that comes with many hugely successful years in his field. He started by outlining how our cities have developed across the world and how, even though applicable at the time, this type of development cannot continue forever. Delving into the threats that face us now and are inevitably set to worsen in the future, he emphasised the importance of changing the ways our cities function and develop.
Using numerous cities, including Adelaide, Australia, as examples he has been heavily involved in, he showed how cities could be, shifting from a linear system on resources in and waste out, to a more circular system with the regeneration and reuse of resources. I won’t dive into all of these methods Girardet explained but you can find a little more information on this website.
Girardet’s main message has now switched from his previous idea of sustainable cities to regenerative cities, saying that now, simply being sustainable is not enough. We need to start giving back and enabling regeneration of our environment, not just sustaining present levels.
After the talk there was a short Q&A session, but unfortunately there was no time for my question. However, he was hanging around afterwards so I managed to grab him then. He was huddled within a group of students which I managed to barge my way into. I asked him whether he thought that these actions and the move to becoming more proactive than reactive was realistically going to happen before we reach the ever looming point where our effects on our planet are completely irreversible. Unfortunately, like myself, he did not. It’s a rather pessimistic end but people like Girardet have spent the majority of their lives trying to take actions to reduce our effects on the world, however there is only so much scientists can do.
We need big cultural changes across the globe and actions to be taken now rather than when it is too late. One thing I have learnt recently is that scientists need to concentrate efforts on policy makers, politicians and governments before any serious action can be taken to attempt to resolve our greedy attitudes to the world we live in and the resources it provides.
