I’ve been making videos with Hubbub for a few years now, investigating everything from where our water comes from to where our recycling goes. This year we decided to pilot a series and try something new. We meet so many incredible people and learn so much about the strange and wonderful world that we wanted to see what would happen if we took a real deep dive into a topic over a whole series. 

Picking a topic was no easy feat with so many directions to explore. Going back to our drawing board of ideas we pulled out a blog that our CEO Trewin had written the summer before, looking at how cities will have to adapt to a changing climate. Cities produce 75% of the world's CO2 and it’s predicted that in just 30 years ⅔ of the global population will live in urban areas. We were hooked on the topic for two reasons. First up, it was clear that if cities are going to hold the majority of the population, they have a major opportunity to support more sustainable living. Secondly, the effects of climate change will mean the way we build and operate cities are going to look vastly different in just a few decades time. It seemed like the perfect combo of practical ways we can design more sustainable living with future gazing into an imaginary sustainable utopia.  

We decided to explore the three key themes of what we build, how we get around and what we eat. Things that will tangibly change the day to day lives of people making their homes in cities, both now and in the future.  

Where will we live? 

This episode looks at sustainable architecture and how our buildings and ways of living will change in the future, from houses on stilts to adapt to rising water levels and car-free communities. In this episode you'll meet architect Satwinder Samra, architect and educator at the University of Sheffield and Marcus Fairs editor of Deezeen and Sue Riddlestone, one of the founders of the BEDzed sustainable housing project. Tune in to find out more and tell us what you think buildings of the future will look like. 

How will we get around?  

Across the UK, almost half of us commute to a completely different area every day for our jobs. We’re travelling long distances each day because we don’t necessarily live where we work. Creating affordable, efficient and sustainable public transport as well as redesigning cities to encourage more walking and cycling is a key part of reducing cities' impacts on the environment. However, it comes with it’s own set of challenges. In this episode Sarah gets the low down on city travel planning from Transport for London and chats to C40 Cities about how transport is adapting across the globe to carry more people than ever before.

What will we eat?  

In 2050, just 30 years away, there will be ten billion people on the planet, which is a lot of mouths to feed. However, the intensive way we have been producing food combined with increasing climate change means there will be less viable land for us to grow food on in the first place. Luckily there are lots of ways people are trying to make the food system more sustainable, which we explore in this episode. We chat to chef Max La Manna and Hubbub food expert Aoife Allen about the trouble with the food industry, and dive into the world of large scale indoor food farming with a visit to James Food Company to find out how local organisations like Growing Communities could change the way we eat. 

What comes next?  

That’s where you come in, we want you to tell us what you want to see next. If you have a question you think deserves a video, an idea for a whole series or something you can’ seem to find the answer to, then set us a challenge.  

Contact us in all the usual places and tag #HubbubInvestigates or #ChallengeHubbub. We’ll see if we can turn your ideas into reality.
