Book excerpt: Markets that function well within a stable regulatory and policy environment are key to improving the productivity and sustainability of the food and agriculture sector. This report contains the main findings and policy lessons gained from a series of wide-ranging country reviews on how government policies can improve sectoral productivity and sustainability through their impact on innovation, structural change, natural resource use, and climate change. Improving the policy environment would require rolling back those policies that distort markets the most and retain farmers in uncompetitive and low-income activities, harm the environment, stifle innovation, slow structural and generational change, and weaken resilience.
