This Manual provides step-by-step guidance on how to apply a culturally sensitive, gender-responsive, human rights-based approach to programming in each of UNFPA’s three core areas of work: population and development, reproductive health, and gender. It also covers how to apply such an approach in the context of a humanitarian emergency. This manual was designed primarily for use by UNFPA Country Staff, but will also be useful for UNFPA implementing partners and others working in the fields of population and development, sexual and reproductive health and reproductive rights, gender equality, and women’s empowerment.
