Louise Gray is author of Avocado Anxiety and Other Stories About Where Your Food Comes From; Sheila Dillon is a food journalist and presenter of Radio 4’s The Food Programme; Duncan Fisher is co-manager of Our Food 1200, a community benefit society re-building a local food economy in Bannau Brycheiniog, Powys & Monmouthshire ; Ian Rasmussen is a senior lecturer at the University of Chester and a Slow Food Cymru Wales member; and Bryce Evans is Professor of Modern World History at Hope Liverpool University.
