Long-distance social relationships have been a feature of human evolutionary history; evidence from the paleoanthropological, archeological, and ethnographic records suggest that one function of these relationships is to manage the risk of resource shortfalls due to climate variability. We should expect long-distance relationships to be especially important when shortfalls are chronic or temporally positively autocorrelated, as these are more likely to exhaust local adaptations for managing risk. Further, individuals who experience shortfalls not as rare shocks, but as patterned events, should be more likely to pay the costs of maintaining long-distance relationships. We test these hypotheses in the context of two communities of Bolivian horticulturalists, where climate variability—especially precipitation variability—is relevant to production and access to long-distance connections is improving.

人们是否通过异地关系管理气候风险?

远距离的社会关系一直是人类进化史上的一个特征;来自古人类学、考古学和人种学记录的证据表明,这些关系的一项功能是管理因气候变化而导致的资源短缺风险。当短缺是长期的或暂时的正自相关时,我们应该期望远距离关系特别重要,因为它们更有可能耗尽管理风险的局部适应性。此外,经历短缺的人不是罕见的冲击,而是模式化的事件,应该更有可能支付维持异地关系的成本。我们在两个玻利维亚园艺家社区的背景下检验这些假设,
