Summary: In this week's programme we have a field report from England with Simon Potts, Professor of Biodiversity and Ecosystem Services at Reading University. Simon Potts's research looks specifically at how effective bees and other pollinators are and their abundance in agricultural landscapes - a crucial link in food security. Monty Don explores some of the issues with Vandana Shiva in Delhi, a board member of the International Forum on Globalisation and an author of over 20 books about biodiversity, food and economies.
