This paper focuses on gender mainstreaming in modeling the impacts of climate change by development sector. Inspired by the methodologies of the Guillaumont economic vulnerability index (2008, 2009) and the UNDP poverty vulnerability ratio (2011), a synthetic index called the ‘Index of Inequality of Gender Vulnerability to Climate Change (IIGVcc)’, which is a modeling by development sector, of vulnerability inequalities to climate change between men and women, is proposed.

Climate change poses serious challenges to the sustainability of fisheries and aquaculture systems, with severe implications for the majority people who depend on them largely for their livelihoods. Therefore, this study investigates factors influencing the vulnerability of fishing activities to climate change among artisanal fisher-folks in coastal area of Lagos, Nigeria. A three-stage random sampling technique was used to select 342 artisanal fishers from the study area.
