27. DROUGHT RISK WHERE RAINFED MILLET IS GROWN IN EAST
AFRICA AND % OF POPULATION AT RISK OF HUNGER
Editor's Notes
Show the breakout of global land use in 2010: about 2/3 of agricultural land is pasture and 1/3 is cropland. And of that cropland, about 1/3 is used for animal feed. Most of the rest is forest/savanna or desert/ice.
Crop demand will increase by 56% between 2010-2050.
Demand for land-intensive foods will increase even more quickly (total meat/dairy increase by 68%, ruminant meat by 88%) during that time.
Even factoring in ongoing improvements in agricultural productivity (at historical rates – not an easy feat!), agricultural land is still likely to expand by ~600 Mha from 2010-2050 (~200 Mha of cropland expansion, ~400 Mha of pasture expansion)
Nearly all of that expansion will be in developing countries where the bulk of the growth in food demand will be (and where yields are low); there will likely be some contraction of ag land at higher latitudes
Context for why we’re bringing agriculture and food information into our Aqueduct water risk platform:
First, because agriculture as a sector is the single largest withdrawer of the world’s freshwater.
