This study examines and analyses behaviours and practices for the management of menstrual hygiene and their impact on the living conditions of sedentary and nomadic women and girls in Niger. The study was carried out in the regions of Maradi, Zinder, Tahoua and Tillabéri under the Joint Programme on Gender, Hygiene and Sanitation in West and Central Africa and implemented by WSSCC and UN Women. The findings of the study reveal various shortcomings, especially in rural areas and, more specifically, among nomadic populations. It highlights that women and girls can fully participate in society and the economy and lead active lives in school, work and leisure if they are better informed. The study also recommends that MHM needs to be clearly articulated in public policies and national strategies with associated budgets and monitoring systems.
