  1. FOOD and CLIMATE Sheffield Climate Alliance Food Group (February 2019)

  2. This is a crisis: Facing up to the age of environmental breakdown Mainstream political and policy debates have failed to recognise that human impacts on the environment have reached a critical stage, potentially eroding the conditions upon which socioeconomic stability is possible. Institute for Public Policy Research 12 Feb 2019

  3. 30% OF ALL GREENHOUSE GASES COME FROM FOOD PRODUCTION (IPPC 2014) Twenty-six percent of the Planet’s ice-free land is used for livestock grazing and 33 percent of croplands are used for livestock feed production.

  4. Analysis of dietary type per daily consumption of 2,000 kcal Dietary greenhouse gas emissions of meat-eaters, fish-eaters, vegetarians and vegans in the UK. Scarborough et al 2014 Springer: http://link.springer.com/article/10.1007/s10584-014-1169-1

  5. Methane is the most potent greenhouse gas because it traps x25 as much heat as carbon dioxide. Methane is released by micro-organisms in animals and plants. Can you name some of the most damaging sources of methane?

  6. Sources of methane: • Lakes and oceans, which are now covering more of the planet because of Arctic warming • Manure lagoons • Stomachs of cows and sheep • Wetlands and rice fields • Fracking, mining, burning wood and vegetation

  7. WASTE UK throwing away £13bn of food each year, latest figures show Waste and recycling advisory body says 4.4m tonnes of household food waste thrown away in 2015 could have been eaten theguardian.com 10/01/2017

  8. Sheffield alone is reported to waste up to £400 million pounds worth of food per year. Sheffield has at least 20 foodbanks and is working through organisations such as Food Works and FareShare to intercept supermarket waste food and either cook with it or quickly distribute it. (also see local resources slide later)

  10. FOOD SECURITY What do you think are some of the threats to food security, worldwide and in the UK?

  11. FOOD SECURITY – GLOBAL AND LOCAL • Lower incomes, yet uncertain harvests and rising prices • Harvests are threatened worldwide • Droughts and floods lead to hunger and famine • Antibiotic use in farming leads to drug-resistant bacteria (UK farm regulations now tightening) • Britain imports 40% of our total food consumption • 3 million tonnes of soya are imported into the UK just to feed farm animals

  12. SOIL Our most precious commodity Generating three centimeters of top soil takes 1,000 years, and if current rates of degradation continue all of the world's top soil could be gone within 60 years, a senior UN official has said. scientificamerican.com

  13. WHAT WE CAN DO as individuals • Modify our diet • Avoid waste • Shop local • Eat seasonal fruit and veg • Avoid packaging • And more...

  14. Why modify our diet? Unless we change our diets, Agriculture Alone Could Produce Enough Emissions to Surpass 1.5°C of Global Warming World Resourced Institute 17 October 2018 Most strikingly, impacts of the lowest-impact animal products typically exceed those of vegetable substitutes, providing new evidence for the importance of dietary change. Poore and Nemecek 2018 (Oxford University study of 40,000 farms) Science pub

  15. CUT DOWN ON FOOD WASTE • How many of these things do you do? • Don’t buy more than you need • Store correctly • Scrub vegetables instead of peeling • If you have a garden, make compost • If not, use a community compost if possible • PLAN shopping and menus • Cook the right amount, get a (second hand?) pressure cooker • Use leftovers • Plan to avoid waste water and energy in cooking • If you boil or steam vegetables, don’t put the water down the drain - it’s full of nutrientsLancet report: we need to cut waste by at least half

  16. Sheffield resources for reducing and reusing waste associated with food. Food Works, various locations Fare Share Yorkshire Food Cycle at St Bart’s S6 Foodhall on Eyre Street Plastic Free shops Unwrapped in Crookes The Bare Alternative on Abbeydale Road New Roots on Glossop Road soon to be plastic free, already sources sustainable food.
