To strengthens capacities of class II and class III officers of the federal government, a manual on Gender Equality Social Inclusion (GESI) and Gender Responsive Budget (GRB) was developed by Nepal Administrative Staff College (NASC) in collaboration with, and with technical support from, UN Women. The manual is the first of its kind, as it brings together two distinct concepts of GRB and GESI and demonstrates how GRB can be used as a tool for advancing GESI in the evolving federal context of Nepal.
