Policy brief
Introduction
Food systems are responsible for a third of global anthropogenic greenhouse gas (GHG) emissions. As the global population grows, so too will the demand for food and, with it, GHG emissions, unless there are substantial changes in global food systems. Improving agricultural efficiency is paramount in mitigating climate change. Traditionally, agricultural productivity has been evaluated as yield per unit of land. However, this approach is no longer sufficient given the urgency of climate change, resource limitations and environmental impacts. This policy brief redefines agricultural productivity as a multifaceted concept that extends beyond area-based yield.
