The Coming Famine: risks andopportunitiesfor global food security Julian Cribb FTSE Nuffield International Conference Adelaide, September 30, 2011
Food demand doubles by 2060s Global food demand
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 “Current estimates indicate we will not have enough water to feed ourselves in 25 years time...” – Colin Chartres, IWMI Groundwater mining Disappearing rivers Vanishing lakes Shrinking glaciers
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 24% of the world’s land is now degraded 1% of the world’s land is being lost each year. Area per person 3Peak land: FAO
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… Peak phosphorus 5 5 Nutrient pollution 5 World P reserves
The Great Waste 5 Food wasted by avg. family in a month. (USDA)
Peak oil: 2006 Algae farms for biodiesel? Peak Oil 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 5 4x more drought Global soil moisture forecast 4 Scientific consensus: 15-25% less food
Knowledge drought 35 R&D stagnation
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: • halfthe present fresh water • farlessland • nofossil fuels (eventually) • scarceand very costlyfertilisers • lesstechnology • insufficient investment • moredrought,heat& floods.
Future conflicts UK Ministry of Defence threat assessment
Government failures Food prices peak twice in three years. The ‘Coming Famine’ is a succession of shocks 6 ▲ Egypt’s regime change began with food price protests
Migrant tsunami Each year: Refugees - 43m Migrants - 205m
Big challenges = Hugeopportunities ‘When the going gets tough, the tough get going’
Solutions1: reinvent food • Reinvent farming & food systems: sustainable, low-input eco-farming • Reinvent the global diet: kills fewer people, damages less planet • Reinvent cities:torecycle 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 • Developeco-farming: more food with less water, energy, soil, chemicals • Designdiets for health and sustainability • Create cities that recycle water, nutrients into novel food systems • Inspirecivilisation with a new ethos and respect for food • Reward farmers for their stewardship of the Earth’s resources.
