In addition to other efforts, work undertaken by the OECD points to a number of short- to medium-term decisions which can potentially improve the outcomes of the agriculture and food system. Some of these processes are either ongoing or are on the agenda of international negotiations. Policies such as these often have specific objectives, e.g. rural development or poverty reduction, which can be pursued more efficiently with more targeted measures. Other policies, such as the promotion of specific non-food uses of biomass, both of agricultural and other origin, should be reviewed for their contribution to the stated objectives and in light of the existing pressures on natural resources. International and regional efforts are currently focused on improving the rules in international trade. Increasing the fluidity of trade links without compromising legitimate domestic objectives for food safety, environmental protection and other areas is important to enable the achievement of the full benefits of comparative advantages.
