Over 50 million people were estimated to be internally displaced by the end of 2020 due to conflict, disasters, human rights violations and violence. Given the multiple drivers of displacement, human rights infringements are often experienced before, during and after displacement. The handbook analyses the role and activities of national human rights institutions (NHRIs) in addressing the human rights dimensions of internal displacement. It provides an overview of good practices, experiences and lessons learned by the UN system and partners.
