Peak Farmland and the Prospect for Land Sparing

expecting that more and richer people will demand more from the land, cultivating wider fields, logging more forests, and pressing nature, comes naturally. the past half-century of disciplined and dematerializing demand and more intense and efficient land use encourage a rational hope that humanity’s pressure will not overwhelm nature. Beginning with the examples of crops in the large and fast-developing countries of india and China as well as the united States, we examine the recent half-century. we also look back over the past 150 years when regions like europe and the united States became the maiden beneficiaries of chemical, biological, and mechanical innovations in agriculture from the industrial revolution. organizing our analysis with the ImPACT identity, we examine the elements contributing to the use of land for crop production, including population, affluence, diet, and the performance of agricultural producers.
