This paper uses global, spatially explicit data to analyze how extensification can be located to meet crop demand in a way that minimizes carbon losses under varying levels of intensification. Carbon-preserving extensification can reduce carbon loss by 7.3 billion tons compared to proportionally increasing extensification by 2050, valued at $1.3 trillion (2012 dollars) based on an estimated social cost of carbon of $181 per ton of carbon (∼$50 per ton CO2).
