The document discusses the potential for agriculture and forestry to mitigate climate change on a global scale. It argues that these sectors could have a huge impact through emissions reductions and carbon sequestration in working landscapes. However, the climate change community remains skeptical due to concerns about permanence, measurement, and whether impacts can be achieved at sufficient scale. The document outlines three key challenges: achieving impacts at large enough scale, facilitating community planning efforts, and generating sufficient market incentives for producers. It then provides examples of initiatives that demonstrate these challenges can be overcome to fully include agriculture and forestry in climate action.
