Converting salt water into drinking water, and accelerating plant growth with coloured light can help provide for more people.
But according to a team based at Cambridge University, it would make more sense to reimagine the global agricultural map.
Their research shows where to situate arable land areas to maximise worldwide yield and minimise environmental impact.
Growing wheat, barley and soybean in southerly midwest America and south of the Sahara would be ideal, as there’s plenty of rain in both.
Large areas of farmland in Europe and India would be best restored to their natural forest state.
Even a partial change would help to significantly reduce CO2 emissions and keep endangered species alive.
A sustainable serving.
