In Senegal, many people are uncertain what their religious traditions teach about birth spacing and family planning. the Cadre des Religieux pour la Santé et le Développement (CRSD) is an interfaith association of Senegalese faith leaders, to promote maternal and child health and clarify religious teachings on family planning. This poster provides an overview of CRSD’s mission and activities, focusing notably on CRSD’s exploration of what Islamic teachings say about family planning; workshops for women’s religious community groups; and CRSD’s exchange visits within the region to encourage the engagement of faith leaders in promoting birth spacing and improve collaboration between faith communities, governments, and other stakeholders.
