including habitat loss It's not quite that simple—in many places increasing yields means using less land. In particular, leaving marginal land fallow. But the factors are pretty complicated, in the US especially dominated by policy: https://www.sciencedirect.com/science/article/pii/S0306919217305560 https://www.sciencedirect.com/science/article/pii/S030691921... On the other hand, how much land was exhausted and then left fallow? How much was taken over for other uses (such as urbanization)? And if we hadn't had yield increases, would we be using more land now? Or just eat less meat? Edit: While worldwide agricultural land has increased, in the US it decreased from 63% to 51% of the total 1949-2007 according to this survey, which draws from USDA data: https://www.ers.usda.gov/amber-waves/2012/march/data-feature-how-is-land-used/ https://www.ers.usda.gov/amber-waves/2012/march/data-feature...
