How to feed the world's ten billion peopleListen to this articleWith the world struggling to feed eight billion people today, how will we feed ten billion by 2050? At the same time, 1.66 billion hectares -- 60% of which is agricultural land -- have been degraded by the very practices we rely on to feed the world. Fortunately, research shows that optimising nitrogen use can boost yields by up to 19% and slash fertiliser use by 15-19%. That requires replacing one-size-fits-all industrial packages with resilient, context-specific systems finely tuned to local soils, water regimes, crops, and climates. Future generations will not ask whether the solutions existed; they will ask what took us so long to implement them.
