Eating differentlyFCRN workshop on changing what we eat Tara Garnett Food Climate Research Network www.fcrn.org.uk Oxford Martin Programme on the Future of Food 22-23 April 2014
Ag livelihoods 1.3bn • Climate – agriculture @15-20% world GHG Rural economies Land use change & deforestation: agriculture 35% ice free surface Biodiversity loss Economy & society Environment Soil, water & air pollution; salinity Food production & consumption Water extraction 70% irrigation-related Animal health & welfare Undernutrition (850 mill) & micronutrient deficiencies (2 bn) Ethics & society Health Food safety Culture & tradition Overnutrition (fat & energy dense) 1.4 bn Public acceptability & trust Food & the big picture: a convergence of concerns Feminisation of agriculture Energy use Food system 20-30% GHG emissions Post harvest employment – processing → vending UK food industry 7.3% GVA) Population growth: 9-10 bn peopleby 2050 Livestock feed: 40% global grains Zoonotic diseases Power, control, equality Models of development Chronic diseases: CHD, strokes, diabetes, cancers
Livestock & meat The convergence converges….
Livestock & meat Occupy 70% agricultural land (1/3 arable land) Consume 40% grains produced Emit 14.5% global GHG emissions Main driver of deforestation, biodiversity loss & land degradation Over 0.75bn poor livestock keepers Can recycle residues & utilise ‘leftover’ land 70% diseases zoonotic in origin Major source water pollution Meat, dairy & nutrition: protein & micronutrients – but saturated fats and energy Meat – culture, tradition, enjoyment Use 15%irrigation water Ethics: Animal rights, animal welfare
Present & possible future influences on food system Today Tomorrow Economic development Population growth Population ageing Urbanisation Changing cultural attitudes & expectations Weather & environmental variability Resource limitations & competition Cost of inputs Food prices China, India • All of today’s, but more acute • Plus…?? • Regulations: national & international - influencing carbon, land, inputs, consumption • Resource pricing land, water, fuel etc (incl PES and carbon pricing). • Resilience issues: environmental and climatic change, extremes and variability, absolute scarcity • Reputational issues: driven by NGOs, media, policy • Randoms: extreme weather, technological breakthroughs, cultural tipping points, wars
Evolving thinking on sustainable diets / sustainable & healthy diets
Within the context of broader narratives about the future of food What future do we want? “The future is already here – it's just not evenly distributed” William Gibson
Narratives around meat – what do we want? Social, economic, commercial, political, biophysical influences Meat-excluding More technological More behavioural Meat-including

Studies generally: Define sustainability in environmental terms (often just GHGs) Are rich-world focused Ignore wider socio-economic context Don’t consider other determinants of nutritional status Don’t consider non-nutritional health implications of food And so, with these (enormous) provisos, can we define
Good-enough/ interim /partialPrinciples of environmentally sustainable and nutritious diets? • Diversity – a wide variety of foods eaten • In energy balance • Based around: tubers and whole grains (but not rice); legumes; fruits and vegetables - field grown and robust • Meat eaten sparingly if at all - all animal parts consumed • Dairy products or fortified plant-substitutes eaten in moderation & other calcium-containing foods consumed • Unsalted seeds and nuts included • Some fish and aquatic products sourced from certified fisheries, although less frequently than Eatwell advises • Limited consumption of sugary and fatty sweets, chocolates, snacks and beverages • Tap water in preference to other beverages

The meat issue. Why is it difficult? • Not an ‘on-off’ issue • Culturally embedded • Taste • Masculinity Rozin et al (2012). “Is Meat Male?

Things that get said Academics : nutrition, environment, ag economics, international development AW, envt, health NGOs Food industry Think tanks
Ways of approaching the issue Influenced by: • Ideologies & values • Disciplinary training • Sectoral lens
Thinking about interventions also need to bear in mind • Cross-transferability from other areas (eg. how far are successful interventions wrt drugs or driving applicable to food?) • Risk of perverse side effects
Workshop aims • What do we know? • What don’t we know? • Where do we know enough to justify action now? • Where is more understanding is needed? • What sort of research would help improve the evidence base needed for effective policy making? • Can we put all that in writing by the end of tomorrow?
