This study examines the welfare effects of the fisheries boom in Lake Victoria, Africa's largest inland fishery. It analyzes the impact of free trade and open access on food security, income distribution, and nutrition. The results highlight improvements in welfare but also challenges such as malnutrition and income disparity. The study emphasizes the importance of improving the status of women for better outcomes.

Conclusions • Welfare has improved slightly 1993-2008 • The fraction of poor reduced in the urban areas • Education level improved both in rural and urban areas • <10 km from lake significantly better off
Conclusions cont. • Substantial real price increases for meat and fish 1993-2008 • Still, unacceptable high numbers of children malnourished (Geheb et al, 2008) • Change of income distribution within hh, men control the fishery income while women often not directly benefit from it (Geheb et al, 2008) • Improving status of women vis-à-vis men likely improves nutrition of children (Smith et al, 2003)
