Tell us what does our Biosphere mean to you?

The Brighton & Lewes Downs Biosphere aims to serve as a world-class demonstration area of how we might live better in the future, in greater harmony with our local environment by bringing people and nature closer together.

We are now part of an international family of ‘Biosphere Reserves’ spanning over one hundred countries, recognised by the United Nations body UNESCO as international sites of excellence of how to meet our needs and improve our environment.

Our Biosphere is all about our local environment however, part of the living surface of our planet where we live and thrive.

The Brighton & Lewes Downs Biosphere covers almost 400 square kilometres of land and sea between the River Adur and the River Ouse, bringing together the three environments of countryside, coast, and city & towns under one united approach. 

Our objectives are to look after and improve our local environment, whilst at the same time developing ourselves in a sustainable way, and promoting better understanding and engagement by people with the world on our doorstep.
