Women involvement in the fishery activities of two coastal communities in Sierra Leone
Women make up an important part of the fishing sector and play critical roles, particularly, in small-scale fisheries and increasingly in capture fishing and other activities. However, the roles of women are often undervalued due to the lack of attention to gender roles in fisheries, especially in Africa. This research was therefore motivated to investigate the roles of women in two coastal communities of Sierra Leone....
