Drawing from data gathered in South Western Madagascar in 2011, the work explores the combination of poverty and traditional gender roles as a critical factor in determining unequal school access among young people from semi-nomadic fishing communities. It demonstrates that from the age of early puberty, most boys go fishing with their fathers and brothers whilst most girls from the same families work at home. In contrast to the school systems observed in many developing society contexts, which demonstrate female marginalisation, in South Western Madagascar both boys and girls are marginalised. Instruments of global policy designs, such as positive discrimination for girls, seem ill-suited to resolve the problem. Instead, the authors call for a more tailored and context-specific approach to address the particular challenges amongst semi-nomadic fishing communities in Madagascar.
