put the world on track to require 40-60% more crops and 70% more milk and meat in 2050 than in 2010 (ref. 1). Even factoring in higher yields, models project that cropland will expand by 100 million to 400 million hectares (Mha) globally over this period 1,2 . Indeed, remote sensing of recent growth rates 3 puts the world's cropland on track to consume 450 million more hectares over this period, an area 1.5 times the size of India.To meet the challenge, countries must do more to maintain or reduce their land carbon footprints. They can do so by boosting crop and livestock yields and by reducing demand, particularly for products that require a lot of land to produce, such as meat.The world must also rapidly reduce its fossil-fuel emissions, with the European Union playing a key part. The bloc is on the cusp of enacting its ambitious 'Fit for 55' plan, designed Burnt land in Pará state, Brazil, where wide tracts of the Amazon rainforest have been cleared for soya-bean production.
