In the Arctic, seasonal variation in the accessibility of the land, sea ice and open waters influences which resources can be harvested safely and efficiently. Climate stressors are also increasingly affecting access to subsistence resources. Within Inuit communities, people differ in their involvement with subsistence activities, but little is known about how engagement in the cash economy (time and money available) and other socio-economic factors shape the food production choices of Inuit harvesters, and their ability to adapt to rapid ecological change. We analyse 281 foraging trips involving 23 Inuit harvesters from Kangiqsujuaq, Nunavik, Canada using a Bayesian approach modelling both patch choice and within-patch success. Gender and income predict Inuit harvest strategies: while men, especially men from low-income households, often visit patches with a relatively low success probability, women and high-income hunters generally have a higher propensity to choose low-risk patches. Inland hunting, marine hunting and fishing differ in the required equipment and effort, and hunters may have to shift their subsistence activities if certain patches become less profitable or less safe owing to high costs of transportation or climate change (e.g. navigate larger areas inland instead of targeting seals on the sea ice). Our finding that household income predicts patch choice suggests that the capacity to maintain access to country foods depends on engagement with the cash economy.

在北极,陆地、海冰和开阔水域的可及性的季节性变化影响着哪些资源可以安全有效地收获。气候压力源也越来越影响到获取生计资源的机会。在因纽特社区中,人们参与生计活动的程度不同,但人们对参与现金经济(可用时间和金钱)和其他社会经济因素如何塑造因纽特采集者的食物生产选择,以及他们适应快速生态变化的能力知之甚少。我们使用贝叶斯方法分析了来自加拿大努纳武特的康格斯夸苏克的 23 名因纽特采集者的 281 次采集活动,该方法同时对斑块选择和斑块内成功率进行建模。性别和收入预测了因纽特人的收获策略:虽然男性,特别是低收入家庭的男性,经常访问成功率相对较低的斑块,但女性和高收入猎人通常更倾向于选择低风险的斑块。内陆狩猎、海洋狩猎和捕鱼在所需设备和努力方面有所不同,如果某些斑块由于运输成本或气候变化(例如在内陆地区航行更大的区域而不是在海冰上捕猎海豹)而变得利润更低或更不安全,猎人可能不得不转移他们的生计活动。我们发现家庭收入预测了斑块选择,这表明维持获取土产食物的能力取决于参与现金经济的程度。本文是主题为“气候变化适应需要文化科学”的一部分。
