Creating a Sustainable Food Future, A Menu of Solutions to Feed Nearly 10 Billion People by 2050,
World Resources Report.
“Increased efficiency of natural resource use is the single most important step toward meeting both
food production and environmental goals. This means increasing crop yields at higher
than historical
(linear) rates, and dramatically increasing output of milk and meat per
hectare of pasture, per animal—
particularly cattle—and per kilogram of fertilizer. If today’s levels of production efficiency were to
remain constant through 2050, then feeding the planet would entail clearing most of the world’s
remaining forests, wiping
out thousands more species, and releasing enough GHG emissions to exceed
the 1.5°C and 2°C warming targets enshrined in the Paris Agreement—even if
emissions from all other
human activities were entirely eliminated.”
