Coastal fisheries communities in sub-Saharan Africa are under high socioeconomic vulnerability in the face of environmental pressures. This article contributes to the current adaptation debate by revisiting the benefits of in-situ adaptation. We assess possible in-situ adaptation strategies amid ongoing vulnerabilities by comparing Ghana and Tanzania. A total of 441 household surveys were conducted in four study sites. The major findings of the study are as follows: First, the three major in-situ adaptation strategies are regular changes of nondestructive fisheries techniques, alternative occupations, and collective action. Second, all three strategies have a significant relationship with income change. Finally, the communities in Tanzania utilized all three strategies more and performed better economically than those in Ghana. On the basis of these insights, we suggest implications of in-situ adaptation for future coastal development in sub-Saharan Africa.

加纳和坦桑尼亚的原地适应和沿海脆弱性

面对环境压力，撒哈拉以南非洲的沿海渔业社区处于高度的社会经济脆弱性之下。本文通过重新审视原位适应的好处，为当前的适应辩论做出了贡献。我们通过比较加纳和坦桑尼亚来评估在持续的脆弱性中可能的原位适应策略。在四个研究地点共进行了 441 次住户调查。研究的主要发现如下： 首先，三大原地适应策略是无损渔业技术的定期变化、替代职业和集体行动。其次，所有三种策略都与收入变化有显着关系。最后，坦桑尼亚社区比加纳社区更多地利用了这三种策略，并且在经济上表现得更好。
