This CIWA Learning Note focuses on capturing lessons learned and recommendations from CIWA’s support to NBI’s gender equality work from 2012 through 2020. This support was provided primarily through the Nile River Basin Support Program and the complementary project, Nile Cooperation for Results. Since support to the NBI operated at both the project and institutional levels, this Note considers lessons learned from past promotion of gender equality and acknowledges the practical realities of sustaining financial and technical contributions to address gender inequalities in a transformative way.
