Challenges and Options for the UK Agri‐Environment: Presidential Address
回顾英国农业环境政策实施15年后的现状，分析当前面临的挑战，比较改进方案，并重点关注短期自愿合同导致的政策效益可持续性弱的问题。
After fifteen years of agri‐environment policy it is now appropriate to take stock of these policies. This is important because these policies are scheduled to expand in the coming decade, their benefits are likely to continue growing and the demand for benefits is also likely to expand. This paper therefore reviews the current agri‐environmental situation, isolating some of the current challenges to the schemes implemented in the UK, and compares main options for their amelioration. Finally it focuses particularly on the “end of contract problem” arising from the weak sustainability of the policy benefits from short‐term voluntary contracts.
