Since its launch in March 2014, the joint programme on ”Gender, Hygiene and Sanitation” has been dedicated to making women’s voices heard and contributing to making their rights a reality, especially the human right to water and sanitation. In just a few months, several large projects have been launched. The study carried out in June in the Louga region of Senegal was one of the first successes. It marks an important milestone because it documents how the lack of suitable facilities affects the everyday lives of women and girls in this region in a very specific way. In this second information letter, we present this survey’s main conclusions and give you an overview of the programme’s different activities and the emerging synergies that will help improve menstrual hygiene management.
