Choices among environmental management alternatives involve tradeoffs where, for example, the benefits of environmental protection may be offset by economic costs or welfare losses to individual agents. Understanding individual or household-level preferences regarding these tradeoffs is not always straightforward, and it often requires an analysis of choices under alternative scenarios. A household survey was used to gather data for a choice experiment, where respondents were asked to choose among pairs of alternative management scenarios about pineapple production in Costa Rica. The experimental design consisted of six attributes that varied on between two and five attribute levels, and the experiment and accompanying survey were administered orally in Spanish. The results show that respondents are willing to make tradeoffs with respect to the management attributes in order to see an overall improvement in environmental quality. Respondents were willing to accept a moderate level of pesticide application, presumably in exchange for paying a lower cost or seeing a gain in another area, such as monitoring or soil conservation. Buffer zones were significant only in the case of large farms. The results have implications for policy decisions that aim to reflect public attitudes, particularly the aspects of pineapple production that matter most to people living near pineapple plantations. The study also highlights the effectiveness of the choice experiment approach in examining household preferences about environmental management in a rural development context.
在环境管理替代方案的选择中,存在权衡取舍,例如,环境保护的好处可能会被个别代理人的经济成本或福利损失所抵消。理解个人或家庭层面对于这些权衡取舍的偏好并不总是那么简单,通常需要对替代情景下的选择进行分析。本研究采用家庭调查收集了关于哥斯达黎加菠萝生产的选择实验数据,在该实验中,受访者被要求在两组不同的管理方案中进行选择。实验设计由六个在两个到五个属性水平上变化的属性组成,实验和相关调查以西班牙语进行口头形式进行。结果表明,受访者愿意在管理属性之间进行权衡,以实现整体环境质量的改善。受访者愿意接受适度的农药使用,可能是为了支付更低的成本或在另一个领域获得收益,例如监测或土壤保护。缓冲区仅在大型农场的情况下才具有重要意义。研究结果对旨在反映公众态度的政策决策具有重要意义,尤其是对居住在菠萝种植园附近的人们来说,菠萝生产的哪些方面最重要。该研究还突出了选择实验方法在农村发展背景下研究家庭对环境管理偏好的有效性。
