Shifts in cropland and trade patterns could feed the world in 2050
How can we grow more crops without taking too much water away from freshwater
ecosystems for irrigation? A new study indicates that it is possible to double
crop production by 2050 without exceeding set limits for water extraction if
more crops are grown in regions with higher rainfall and with corresponding
shifts in international trade and agricultural management. However, without
appropriate safeguards, and if we follow the current business-as-usual scenario,
this could come at the ecological cost of converting natural land and forest
into cropland. This research provides a 'first-step' in analysing potential
trade-offs in the global food-trade-water nexus.
