目前缺乏对非洲农村人口动态与家庭使用自然资源之间关系的研究。这项工作很重要，因为在非洲农村，自然资源为家庭提供了抵御冲击的缓冲，既提供了生计，又提供了创收潜力。文章的重点是成人死亡率作为一个家庭的冲击，检查使用当地环境资源与家庭的饮食需求。作者分析了2004年5月至12月期间在南非农村地区MRC/Wits农村公共卫生和卫生转型研究单位（Agincourt）收集的两个数据来源。定量分析使用了240个家庭的调查数据，按成人死亡率经验分层。定性数据是根据对最近经历过成人死亡的家庭成员进行的31次访谈得出的。访谈提供了深入了解各种家庭一级的死亡率的影响，也表明了近距离资源的重要性，在维持粮食安全的成年家庭成员的损失。从数量上看，失去一个成年人的家庭和没有失去一个成年人的家庭在自然环境的使用模式和粮食安全水平方面都存在重大差异。死亡率与家庭对当地环境资源的使用之间的关系还受到死者性别和死亡后时间的影响。成人死亡率，特别是男性工薪族的死亡，影响到家庭粮食安全。随着资源收集责任的转移，时间分配受到影响，野生食品可能取代以前购买的商品。
There is currently a lack of research on the association between demographic dynamics and household use of natural resources in rural Africa. Such work is important because in rural Africa natural resources buffer households against shocks, offering both sustenance and income-generating potential. The article focuses on adult mortality as a household shock, examining use of local environmental resources as related to household dietary needs. The authors analyze two sources of data collected during May–December 2004 in the MRC/Wits Rural Public Health and Health Transitions Research Unit (Agincourt) in rural South Africa. Quantitative analyses use survey data from 240 households, stratified by adult mortality experience. Qualitative data are based on 31 interviews with members of households having recently experienced adult mortality. The interviews provide insight into a variety of household-level mortality impacts and also suggest the importance of proximate resources in the maintenance of food security following the loss of an adult household member. Quantitatively, there are significant differences, both in patterns of usage of the natural environment and in levels of food security, between households that have lost an adult and those that have not. The association between mortality and household use of local environmental resources is further shaped by the gender of the deceased and the time elapsed since the death. Adult mortality, particularly the death of a male wage-earner, affects household food security. Time allocation is affected as resource collection responsibilities shift, and wild foods may substitute for previously purchased goods.
