Multifunctionality of agriculture: an inquiry into the complementarity between landscape preservation and food security
以挪威为例，研究农业在提供粮食安全和景观保护等公共品时的成本互补性，发现当前支持政策目标不准且过度，建议转向支持土地集约型生产。
Without support, the levels of agricultural public goods such as food security and landscape preservation would fall short of demand in high-cost countries. However, as demonstrated by Norway as a case study, the current level of support is disproportionate from a public goods perspective, and the policy instruments are badly targeted at the public goods in question. Because agricultural land is a major component of both food security and landscape preservation, giving rise to a high degree of cost complementarity between the public goods, it would be more efficient to support land-extensive production techniques than production per se.
