Do we only have 100 (or 60… or even just 30!) harvests left, as now many reports and media headlines have asserted? Our guest for Episode 13 of Learning to Fly, Professor Jess Davies, responded to this terrifying claim by deciding to knuckle down and see what scientific corroboration it has. As such, it is also a perfect example of the kind of high-impact interdisciplinary and myth-busting work she and her colleagues are now doing on numerous questions regarding the key issues of futures of food and agricultural systems. Join us for illuminating discussion not just about some key issues of the sustainability and resilience of our food systems – ranging from soil and its degradation, to urban farming –; but also about the key role for science (i.e. science FOR and in the Anthropocene) of removing obstructions to skilful practical responses to current problems, in terms of both plugging knowledge gaps and puncturing mistaken received wisdoms, and hence in deliberately and concertedly reaching out to publics, not just experts, in circulating its findings.
