The Coming Famine : risks and opportunities for global food security Julian Cribb FTSE Nuffield International Conference Adelaide, September 30, 2011
A ‘wicked’ problem.... DEMAND: 242,000 more people every day More babies + longer lives Population >10-11 bn Food demand soars in emerging economies >600 petacalories/day Total food demand to double by 2060s CONSTRAINTS: ‘Peak water’ ‘Peak land’ ‘Peak oil’ ‘Peak P’ ‘Peak fish’ ‘R&D drought’ ‘Capital drought’ ‘Climate extinction’
Peak water Disappearing rivers Vanishing lakes Groundwater mining Shrinking glaciers “Current estimates indicate we will not have enough water to feed ourselves in 25 years time...” – Colin Chartres, IWMI
Food embodies water... Total human water use: 7450 cubic kms We each use 1240t/yr In a lifetime, we use: 100,000 tonnes
Peak Land : 2001 1% of the world’s land is being lost each year. Peak land: FAO 24% of the world’s land is now degraded Area per person
Megacities: mega-risks By 2050... 7.7 billion will live in cities Total urban area = China Urban water use 2800 cu kms Cities cannot feed themselves By 2030...
Nutrients are finite… Nutrient Nutrientpollution Peak phosphorus World P reserves
The Great Waste Food wasted by avg. family in a month. (USDA)
Peak Oil Peak oil: 2006 Algae farms for biodiesel? Food & oil prices are in lockstep
Peak fish: 2004 “The maximum wild capture fishery potential from the world’s oceans has probably been reached.” - FAO
Climate instability 4x more drought Global soil moisture forecast Scientific consensus: 15-25% less food
Capital drought Doubling food production requires $90bn+ a year for 50 years: FAO Declining market power of farmers due to supply chain globalisation Displacement of > 1.5 billion small farmers > Need to rethink the economics of agriculture > need to change the consumer signal to encourage new investment, sustainable systems, conservation of land, water, crops etc
The food challenge Double global food output with: - half the present fresh water - far less land - no fossil fuels (eventually) - scarce and very costly fertilisers - less technology - insufficient investment - more drought, heat & floods.
Future conflicts UK Ministry of Defence threat assessment
Government failures ▲ Egypt’s regime change began with food price protests Food prices peak twice in three years. The ‘Coming Famine’ is a succession of shocks
Big challenges = Huge opportunities ‘When the going gets tough, the tough get going’
Solutions Solutions 1: reinvent food Reinvent farming & food systems : sustainable, low-input eco-farming Reinvent the global diet: kills fewer people, damages less planet Reinvent cities: to recycle water, nutrients, energy
Solutions 2 Double food R&D to $80bn globally a year (from $1.6 Tr weapons’ spend) Invest $80bn to share the food knowledge among farmers, cooks, consumers Invest $90bn+ a year in new farm & grazing systems End waste: recycle all organic waste and water into new food & resource industries Educate people to respect and value food.
Solutions: A Food Year A Food Year in every junior school on the planet Teach new respect for food: how to eat for health and sustainability OR ?
Averting the Coming Famine Develop eco-farming: more food with less water, energy, soil, chemicals Design diets for health and sustainability Create cities that recycle water, nutrients into novel food systems Inspire civilisation with a new ethos and respect for food Reward farmers for their stewardship of the Earth’s resources.
