GPOBA is a global partnership program in the World Bank Group. Through a diverse portfolio of projects, GPOBA funds, designs, demonstrates and documents output-based aid approaches (OBA) to improve the delivery of basic services in  developing  countries. Large development projects too often fail to include the very poor, and GPOBA is dedicated to making sure the poor and marginalized  have access to  electricity, water, sanitation, health care, education and other basic services necessary for growth and opportunity.
