This Reference Manual provides a compendium of existing practice that spotlights the United Nations Development Programme’s (UNDP) approach towards strengthening information integrity in support of electoral institutions and processes. It leverages insights from a diversity of programming initiatives at the global, regional and local levels and provides a consolidated overview of programmatic approaches and initiatives. In doing so, the Reference Manual serves as a key reference tool for UNDP and its partners to identify appropriate and effective interventions, and to define their scope and timing to prevent, manage or mitigate the impact of information pollution on electoral institutions and processes.
