Agricultural land protection (ALP) is a standard policy response to a desire for food security. However, ALP may result in a misallocation of resources. Examining rice land policy in Vietnam, we determine the optimal level of rice land protected against other crops using a stochastic optimization model built on top of a general equilibrium framework, combined with sequential micro-simulations on household data. We find that converting part of protected rice land enhances economic efficiency. Nonetheless, the policy is relatively pro-rich, implying a trade-off between poverty reduction and economic efficiency, making some households in already poor areas worse off. Our approach can be applied to land-use planning generally, highlighting the relevant tradeoffs and the search for needed optimal land-use policies.
农业用地保护(ALP)是保障粮食安全需求的一项标准政策举措。然而,农业用地保护可能会导致资源配置不当。通过研究越南的稻田政策,我们使用基于一般均衡框架构建的随机优化模型,并结合对家庭数据的序贯微观模拟,来确定为抵御其他作物而受保护的稻田的最优水平。我们发现,将部分受保护的稻田进行转换可提高经济效率。尽管如此,该政策相对有利于富人,这意味着在减贫与经济效率之间存在权衡,使一些贫困地区的家庭状况变得更糟。我们的方法通常可应用于土地利用规划,突出相关权衡以及对所需最优土地利用政策的探索。
