The main objective of this study is to assess the economic value of the Brazilian Amazon's ecosystem services accruing to Brazilians based on a meta-analysis of the Brazilian valuation literature. Insight in these local values provides an important benchmark to demonstrate the importance of preserving the Brazilian Amazon forest. The review covers almost 30 years of Brazilian valuation research on the Amazon, published predominantly in Portuguese, highlighting a high degree of study and data heterogeneity. The estimated mean value of the provision of habitat for species, carbon sequestration, water regulation, recreation and ecotourism to local populations is about 410 USD/ha/year. The standard deviation is however high, reflecting a wide dispersion in the distribution of values. Between 50 and 70 percent of the variation in these values can be explained with the help of the estimated meta-regression models, resulting in considerable prediction errors when applying a within-sample resampling procedure. These findings demonstrate the need for a more robust, common ecosystem services accounting and valuation framework before these values can be scaled up and aggregated across the entire Brazilian Amazon.
本研究的主要目的是评估巴西亚马逊生态系统服务对巴西人的经济价值，方法是对巴西评估文献进行荟萃分析。了解这些本地价值为展示保护巴西亚马逊森林的重要性提供了一个重要的基准。该综述涵盖了近 30 年巴西对亚马逊的评估研究，主要以葡萄牙语发表，突出了研究和数据异质性的高度。为当地居民提供物种栖息地、碳固存、水资源调节、娱乐和生态旅游等服务的估计平均值约为 410 美元/公顷/年。然而，标准差很高，反映了价值分布的广泛离散。在这些价值的 50%至 70%可以用估计的荟萃回归模型来解释，这导致在应用样本内重采样程序时会产生相当大的预测误差。这些发现表明，在这些价值可以扩大规模并在整个巴西亚马逊地区汇总之前，需要一个更稳健、通用的生态系统服务核算和评估框架。
