A major challenge to reduce forest loss in the tropics is to incentivize conservation on private land in agricultural settings. Engaging private landowners in conservation schemes is particularly important along deforestation frontiers, such as in the southern Brazilian Amazon. While we know much about what motivates landowners to participate as providers, or sellers, of conservation schemes, understanding what motivates landowners who act as buyers, that is, those who require land to meet conservation obligations, remains lacking. Here we identify viewpoints of sellers and buyers of an emerging forest certificate trading scheme in Brazil and quantify the compatibility of their views to examine potential barriers to trade. Sellers and buyers could be divided into three groups, but only one group in each case was positive about participating in the scheme. A key concern of buyers was the desire for establishing contracts with a long duration; in contrast, price was a key issue for sellers. Addressing these concerns by defining minimum contract lengths and restricting the spatial scale of transactions will be essential if this scheme is to realise its potential to reduce rates of deforestation.

不同土地所有者的期望可能会阻碍采用森林证书交易计划

减少热带地区森林流失的主要挑战是，鼓励在农业环境中保护私有土地。在森林砍伐地区，例如巴西南部的亚马逊河地区，让私人土地所有者参与保护计划尤为重要。尽管我们对激励土地所有者作为保护方案的提供者或卖方的动机知之甚少，但仍然缺乏了解激励作为购买者的土地所有者（即那些需要土地履行保护义务的人）的动机。在这里，我们确定了巴西新兴森林证书交易计划的买卖双方的观点，并量化了他们的观点的兼容性，以研究潜在的贸易壁垒。卖方和买方可以分为三类，但在每种情况下，只有一个小组对参加该计划持积极态度。买家最关心的是建立长期合同的愿望。相反，价格是卖方的关键问题。如果此方案要实现其减少毁林率的潜力，则通过定义最小合同期限和限制交易的空间规模来解决这些问题将至关重要。
