Researchers recognize that society needs accurate and comprehensive estimates of the economic value of rain forests to assess conservation and management options. Valuation of forests can help us to decide whether to implement policies that reconcile the value different groups attach to forests. Here we have measured the value of the rain forest to local populations by monitoring the foods, construction and craft materials, and medicines consumed or sold from the forest by 32 Indian households in two villages in Honduras over 2.5 years. We have directly measured the detailed, comprehensive consumption patterns of rain forest products by an indigenous population and the value of that consumption in local markets. The combined value of consumption and sale of forest goods ranged from US$17.79 to US$23.72 per hectare per year, at the lower end of previous estimates (between US$49 and US$1,089 (mean US$347) per hectare per year). Although outsiders value the rain forest for its high-use and non-use values, local people receive a small share of the total value. Unless rural people are paid for the non-local values of rain forests, they may be easily persuaded to deforest.
研究人员认识到,社会需要对雨林的经济价值进行准确而全面的评估,以便评估保护和管理方案。森林估值有助于我们决定是否实施能协调不同群体赋予森林的价值的政策。在此,我们通过监测洪都拉斯两个村庄的32户印第安家庭在2.5年时间里从森林中获取或售卖的食物、建筑和工艺材料以及药品,来衡量雨林对当地居民的价值。我们直接测量了当地居民对雨林产品的详细、全面的消费模式以及这些消费在当地市场的价值。森林产品消费和销售的综合价值为每年每公顷17.79美元至23.72美元,处于此前估值范围(每年每公顷49美元至1089美元(平均347美元))的低端。尽管外来者因雨林的高使用价值和非使用价值而重视它,但当地人在总价值中所占份额却很小。除非农村居民因雨林的非本地价值而得到补偿,否则他们可能很容易被说服砍伐森林。
