This chapter asks whether evidence supports the widely held belief that land used for agriculture around the world has continued to rapidly expand via conversion of natural habitat in response to the demands created by recent human population growth. Contrary to conventional wisdom, global agricultural land use peaked in 1998 and has since declined. While habitat continues to be cleared for agriculture, on a global net basis, more agricultural land has been converted to other uses than vice versa. This analysis also found that national trends in agricultural expansion are driven by factors other than population growth. Although this does not mean agriculture is “sustainable,” these findings challenge the dominant narrative around global agricultural expansion and highlight other important issues that must be addressed. Looking at data at national and subnational scales is essential to understand the implications of global trends in agriculture, where improvements and interventions are most needed.
