From Pakistan to Bulgaria to swimming the waterways of Britain: Rana Mitter is joined by a panel of writers to look at our relationship with particular landscapes and the natural world. Kapka Kassabova’s latest book Elixir: In the Valley at the End of Time details her stay in a remote valley by the River Mesa in Bulgaria and the knowledge of herbalism she finds there. Patrick Barham's latest book is about Roger Deakin, the environmentalist who co-founded Common Ground and was passionate about wild swimming. New Generation Thinker Noreen Masud from the University of Bristol has written a memoir called A Flat Place which details the impact of displacement from her Pakistani roots and her pilgrimage to the low lying landscapes of Orkney, Morecambe Bay and Orford Ness. The programme is part of Radio 3's broadcasts from the 2023 Hay Festival and was recorded in front of an audience there earlier this week. You can find a collection of discussions about Green Thinking all available to download or on BBC Sounds on the Free Thinking programme website of BBC Radio 3.
