最近将减贫与森林养护联系起来的研究往往侧重于非木材森林产品商业化的潜在贡献，因此强调非木材森林产品的收入，而不是其消费。本文旨在了解野生食用植物的消费在农村人口的生计中所发挥的作用。两种方法的评估是用来估计的Pwo克伦人生活在泰国西部的Thung Yai Naresuan野生动物保护区消耗的野生食用植物的价值。第一种方法计算采集野生食用植物所需的时间（每户每年14.63天），第二种方法使用市场上商业替代品的价格来估计家庭成员如果转向商业食用作物将不得不从事有偿工作的天数（每年143天）。本文的结论是，食用野生食用植物是一种有效的生存方式，应予以鼓励。如果不加以鼓励，经济增长可能导致人们将额外的现金收入浪费在地位较高的商业粮食作物上，而不是将其用于生产性投资。
Recent research linking poverty alleviation and forest conservation has frequently focused on the potential contribution of the commercialization of Non-Timber Forest Products (NTFPs), and has consequently emphasized incomes from NTFPs rather than their consumption. This paper aims to understand the role played by the consumption of wild food plants in the livelihood of rural populations. Two methods of evaluation are used to estimate the value of the wild food plants consumed by Pwo Karen people living in the Thung Yai Naresuan Wildlife Sanctuary in western Thailand. The first calculates the time needed to gather the wild food plants (14.63 days/year per household), and the second uses the prices of commercial substitutes in the market to estimate the number of days household members would have to engage in paid work if they switched to commercial food crops (143 days/year). The paper concludes that consuming wild food plants is an efficient method of subsistence that should be encouraged. If it is not encouraged, economic growth could lead people to squander additional cash incomes on higher-status commercial food crops rather than spend it on productive investment.
