<p>Global workforces are experiencing an increase in occupational dangers due to climate change. Southern Africa has a distinct vulnerability profile due to its high level of informal employment and substantial reliance on climate-sensitive industries. There are significant gaps in the understanding of how climate stressors impact employee productivity, safety, and the pillars of decent work in Southern Africa because the majority of previous research has concentrated on environmental effects. The review paper synthesizes evidence of occupational risks induced by climate, health effects, and adaptation strategies as well as their limitations in work sectors of Southern Africa. PRISMA-ScR guidelines were followed by the review. English literature published between 2015 and 2025 was searched from four databases, including Google Scholar, Science Direct, Web of Science, and Scopus. The literature was screened following the inclusion and exclusion criteria and synthesized thematically. Disaster management, informal work, tourism, fisheries, construction, mining, and agriculture sectors face worsening flooding, heat stress, mental health challenges, and vector-borne diseases. Certain temperature thresholds cause productivity to drop, yet informal laborers are not equipped with safety gear. Adaptation is still not systematic, but rather reactive and engineering-focused. Resource scarcity, inadequate enforcement of regulations, and limited worker understanding of climate-related risks are major obstacles. All pillars of ILO Decent Work are undermined by climate change. However, labour polices in Southern Africa are limited in terms of addressing that. Inadequate safety measures and growing occupational climate dangers in Southern Africa represent a serious gap. There is a need for worker-centered mandated policies, climate labor regulations, and social protection integration.</p>
