在生物多样性的保护方面,原住民族通常被认为是潜在的同盟者。本文中我们对原住民的民族植物学技能是否有助于减少热带雨林的采伐进行了评估。我们调查了玻利维亚的一个土著亚马孙族群—提斯曼人的128个家庭的男性家庭户主的民族植物学技能并且测定了他们为农业而采伐的雨林面积。我们应用多元回归分析来推测在对学校教育、健康状况、采伐的地块数量、家庭的成年人口以及居住的村庄进行控制时民族植物学技能和采伐的雨林面积的关系。我们发现当男性家庭成员的民族植物学技能加倍时,每户家庭采伐的热带雨林的数量减少了25%。这种联系在被采伐的老龄林面积作为因变量时比采伐的休耕林的面积作为因变量时更强烈。依靠森林生存的人可能会比不利用森林的人更看重林分的价值,因此他们可能更不情愿采伐森林。
Indigenous peoples are often considered as potential allies in biodiversity conservation. In this paper, we evaluate whether Aboriginal ethno-botanical skills contribute to reducing the harvest of tropical rain forests. We investigated the ethnobotany skills of male heads of household in 128 indigenous Tiszanates in Bolivia, and measured the area of rainforests they harvested for agriculture. We use multiple regression analysis to speculate on the relationship between ethnobotany skills and harvested rainforest area in terms of schooling, health, number of harvested plots, adult population of the household, and the village in which they live. We found that when the ethnic botany skills of male family members doubled, the number of tropical rainforests harvested per household decreased by 25%. This connection is stronger when the area of harvested cane trees is used as dependent variable than that of harvested fallow forests. People dependent on forests may value the value of forests more than those who do not, so they may be more reluctant to deforest.
