An open and inclusive public sphere is not only a condition for the realization of the right to participate in the conduct of public affairs. It is also an enabler of peace and development. For this reason, promoting an open and inclusive public sphere is a key component of UNDP’s work in the area of governance. This set of three documents – “What is an open and inclusive public sphere? A framing note”, “Promoting an open and inclusive public sphere. Programmatic options” and “Promoting an open and inclusive public sphere. At a glance” – outline how UNDP leverages its unique comparative advantage to advance the principles of openness and inclusion within governance systems.
