Measuring the Opportunity Cost of Carbon Sequestration in Tropical Agriculture
提出一种测量热带农场碳封存机会成本的方法，估算菲律宾农业流域通过土地改造和农林业储存碳的现值成本，发现农林业比纯林木系统成本更低。
<i>We present a method for measuring the opportunity cost of sequestering carbon on tropical farms. We derive the rates of carbon sequestration for timber and agroforestry systems and compute incentive compatible compensating payment schedules for farmers who sequester carbon. The method is applied to data for an agricultural watershed in the Philippines. Area- and land quality-adjusted total costs are estimated. The present value of the opportunity cost of carbon storage via land modification falls between $3.30 and $62.50 per ton. Carbon storage through agroforestry is found to be less costly than via a pure tree-based system.</i>
