Senegal's humanitarian needs are driven mainly by recurring floods during the rainy season and food insecurity, both of which are exacerbated by the effects of climate change. The country also hosts a high number of refugees originating mostly from Mauritania. In instances of displacement, women and girls are more vulnerable to exploitation and violence and are often unable to access life-saving health care. UNFPA works to improve awareness of and access to sexual and reproductive health services and supports mechanisms to prevent and respond to gender-based violence.
