The paper provides an analysis of adaptation of fishers’ households to climate change around Jebba Lake Basin, Nigeria. Fisheries of Jebba Lake Basin are presented as a system of dynamic trends, seasonality and shock. An analysis of livelihood diversification reveals that some households are more adaptable to environmental change than others. Fishers who have become overly specialised in fishing as sole livelihood activity are least able to adapt. The study thus recommends increased capabilities of fishers through formal enlightenment campaigns in respect of other livelihood portfolios outside fishing for better livelihood diversification.
