Hot on the heels of the global biodiversity conference in Nagoya, Japan we will be talking about biodiversity and how to stem the global tide of species loss. My guests are Dr Andrew Mitchell from the Global Canopy Programme whose new publication the Little Biodiversity Finance Book suggests that we need to understand the value of nature in pounds and pence before we can understand how best to preserve it. Also with me will be Juliette Jowit, environment editor at the Observer to talk about the paper’s Piece by Piece project which brings together a diversity of local campaigns throughout the UK aimed at preserving local habitats
