The value of local participation is presented in five case studies on public-private partnerships for family planning: Marie Stopes Papua New Guinea, Sehat Sahulat Card in Pakistan, Sayana Press implementation in Senegal, Wazazi Nipendeni in Tanzania, and accredited drug dispensing outlets in Tanzania. The publication begins by discussing partnership mechanisms and the types of partners. The authors consider the experience of PPP unit representatives that worked on health issues, including family planning. The primer closes with a discussion about ongoing challenges and opportunities for these partnerships.
