Abstract

Fisheries in Sub-Saharan Africa are vulnerable to the effects of climate change, which include changes in mean temperature, increasing rainfall variability and the occurrence of extreme weather events. This article reviews evidence on the magnitude of climate change and the nature of its impacts on both inland and marine fisheries. In addition, the review also focuses on the impacts of climate change on fishery-dependent communities and finally highlights climate change adaptation strategies adopted by fishers. A systematic approach was employed to search and select relevant published literature used in this review paper. The reviewed literature indicated the challenge of declining fish catches in several fishing communities, which was associated with climate change and variability. Changes in mean temperature, rainfall quantities and patterns, sea-level changes, water salinity, and lake levels affect fish productivity. Fishers in sub-Saharan Africa adopt different strategies to sustain their livelihoods and food security, which are being threatened by climate change. Adaptation strategies employed by fishers to cope with the impacts of climate change include, changing fishing gear, migration, targeting new species, and increasing fishing grounds and time spent fishing. To promote socio-ecological adaptation and fisheries sustainability, it is crucial to understand the impacts of climate change at a local level, which would inform policy and fisheries management practices.

摘要

撒哈拉以南非洲的渔业容易受到气候变化的影响，其中包括平均温度的变化、降雨量的增加和极端天气事件的发生。本文回顾了有关气候变化幅度及其对内陆和海洋渔业影响性质的证据。此外，审查还侧重于气候变化对依赖渔业的社区的影响，并最终突出了渔民采用的气候变化适应战略。本综述采用系统方法来搜索和选择相关的已发表文献。审查的文献表明，几个渔业社区的渔获量下降面临着挑战，这与气候变化和多变性有关。平均温度、降雨量和模式的变化，海平面变化、海水盐度和湖泊水位影响鱼类生产力。撒哈拉以南非洲的渔民采取不同的策略来维持他们正受到气候变化威胁的生计和粮食安全。渔民为应对气候变化影响而采用的适应策略包括：更换渔具、迁徙、瞄准新物种以及增加渔场和捕鱼时间。为了促进社会生态适应和渔业可持续性，了解气候变化在地方层面的影响至关重要，这将为政策和渔业管理实践提供信息。它们正受到气候变化的威胁。渔民为应对气候变化影响而采用的适应策略包括：更换渔具、迁徙、瞄准新物种以及增加渔场和捕鱼时间。为了促进社会生态适应和渔业可持续性，了解气候变化在地方层面的影响至关重要，这将为政策和渔业管理实践提供信息。它们正受到气候变化的威胁。渔民为应对气候变化影响而采用的适应策略包括：更换渔具、迁徙、瞄准新物种以及增加渔场和捕鱼时间。为了促进社会生态适应和渔业可持续性，了解气候变化在地方层面的影响至关重要，这将为政策和渔业管理实践提供信息。
