The 2015 El Niño-triggered drought in Southern Africa caused widespread economic and livelihood disruption in South Africa, imposing multiple physical and health challenges for rural populations including people living with HIV (PLHIV). We examined the economic, social and demographic impacts of drought drawing on 27 in-depth interviews in two cohorts of PLHIV in Hlabisa, uMkhanyakude district, KwaZulu-Natal. Thematic analysis revealed how drought-enforced soil water depletion, dried-up rivers, and dams culminated in a continuum of events such as loss of livestock, reduced agricultural production, and insufficient access to water and food which was understood to indirectly have a negative impact on HIV treatment adherence. This was mediated through disruptions in incomes, livelihoods and food systems, increased risk to general health, forced mobility and exacerbation of contextual vulnerabilities linked to poverty and unemployment. The systems approach, drawn from interview themes, hypothesises the complex pathways of plausible networks of impacts from drought through varying socioeconomic factors, exacerbating longstanding contextual precarity, and ultimately challenging HIV care utilisation. Understanding the multidimensional relationships between climate change, especially drought, and poor HIV care outcomes through the prism of contextual vulnerabilities is vital for shaping policy interventions.
2015年由厄尔尼诺引发的南非干旱给南非造成了广泛的经济和生计破坏,给农村人口(包括艾滋病毒感染者)带来了多重身体和健康挑战。我们通过对夸祖鲁-纳塔尔省乌姆卡尼亚库德区赫拉比萨两个艾滋病毒感染者队列进行的27次深入访谈,研究了干旱的经济、社会和人口影响。主题分析揭示了干旱导致的土壤水分耗尽、河流干涸和水坝枯竭如何引发了一系列事件,如牲畜损失、农业产量下降以及获得水和食物的机会不足,这些被认为间接对艾滋病毒治疗依从性产生了负面影响。这是通过收入、生计和粮食系统的中断、总体健康风险增加、被迫迁移以及与贫困和失业相关的背景脆弱性加剧来介导的。从访谈主题中得出的系统方法假设了干旱通过不同社会经济因素产生的合理影响网络的复杂路径,加剧了长期存在的背景不稳定,最终对艾滋病毒护理利用构成挑战。通过背景脆弱性的视角理解气候变化(尤其是干旱)与不良艾滋病毒护理结果之间的多维度关系,对于制定政策干预措施至关重要。
