Solutions for a cultivated planet
Increasing population and consumption are placing unprecedented demands on
agriculture and natural resources. Today, approximately a billion people are
chronically malnourished while our agricultural systems are concurrently
degrading land, water, biodiversity and climate on a global scale. To meet
the world’s future food security and sustainability needs, food production
must grow substantially while, at the same time, agriculture’s
environmental footprint must shrink dramatically. Here we analyse solutions
to this dilemma, showing that tremendous progress could be made by halting
agricultural expansion, closing ‘yield gaps’ on underperforming lands,
increasing cropping efficiency, shifting diets and reducing waste. Together,
these strategies could double food production while greatly reducing the
environmental impacts of agriculture.
