EmpiricalRequires evidence
Ten billion can eat within planetary limits if farming is redesigned.
The claim
Kept strictly within four planetary boundaries, today's food system could feed about 3.4 billion people; with redistributed cropland, better water and nutrient use, less waste and diet shifts it could feed 10.2 billion.
Argument role: boundary. Smil reports a recent study (Gerten et al. 2020, by my identification). One model study, so likelihood moderate. The combination is the core food-abundance claim: the physical limit is not land or nutrients but management, waste and diet, each a lever that coordination and cheap sensing can pull.

If all those boundaries were strictly respected, the global food system could supply balanced daily diets, about 2,400 kilocalories per capita, to no more than 3.4 billion people. But the 10.2 billion could be supported with the redistribution of cropland, better water and nutrient management, food waste reduction, and dietary adjustments.
