I really enjoyed this, thanks so much for pointing me to it. I like the phrase ‘blue and green infrastructure’ very much. In the UK we (by which I mean our local government) are not good at seeing outdoor pools as infrastructure. The focus is on the indoor leisure centres and the outdoor pools are often seen as an inconvenience and an oddity, so they are mismanaged to the point where they generate little income and then fall under threat of closure. A mind shift is definitely needed here.
