Within South East Asia, certification and local market development may play an important role in incentivizing farmers to continue with nature-based solutions delivered by organic or traditional farming practices and avoid using environmentally detrimental production techniques. The purpose of this study is to use economic valuation in order to achieve an empirical understanding of local consumer preferences for different attributes of rice products. Application of the agrarian system approach reveals that rice cultivation systems observed in the Tonle Sape Lake of the Mekong River Basin in Cambodia (our study case) may target three ecosystem services that present the characteristics of public goods and may benefit consumer support. A choice experiment survey was administered among local consumers in the city of Phnom Penh in 2013. Econometric analysis indicates high rate of non-attendance for the price attribute. It also suggests that 17% of the respondents made their choices neglecting attributes describing ecosystem services. However, there are evidence of consumers' willingness to pay (WTP) for certified organic rice higher than the price-premium observed on the local market. Furthermore, there is additional WTP value for the preservation of ecosystem services. We discuss the implications of our findings on potential payment for ecosystem services in the specific case of rice.

在东南亚地区，认证和本地市场开发可能在激励农民继续采用有机或传统耕作方式提供的基于自然的解决方案，避免使用对环境有害的生产技术方面发挥重要作用。这项研究的目的是利用经济价值评估，以便对大米产品不同属性的当地消费者偏好进行实证理解。农业系统方法的应用表明，在柬埔寨湄公河流域的洞萨普湖中观察到的水稻种植系统（我们的研究案例）可能针对三种具有公共产品特征的生态系统服务，并可能受益于消费者的支持。2013年，对金边市的本地消费者进行了一项选择实验调查。计量经济学分析表明，价格属性的缺勤率很高。它还表明，有17％的受访者在选择时忽略了描述生态系统服务的属性。但是，有证据表明，消费者愿意为经过认证的有机大米支付的价格高于当地市场上的溢价。此外，保护生态系统服务还具有额外的WTP价值。我们讨论了我们的发现对特定水稻案例潜在的生态系统服务付款的影响。经认证的有机大米的支付意愿（WTP）高于当地市场上的价格溢价。此外，保护生态系统服务还具有额外的WTP价值。我们讨论了我们的发现对特定水稻案例潜在的生态系统服务付款的影响。经认证的有机大米的支付意愿（WTP）高于当地市场上的价格溢价。此外，保护生态系统服务还具有额外的WTP价值。我们讨论了我们的发现对特定水稻案例潜在的生态系统服务付款的影响。
