Millions of people around the world are affected by forced displacement due to violent conflict, persecution, human rights violations, natural disasters and degrading ecosystems. Recurrent cycles of displacement are frequently explained by the intricate interaction of several underlying causes, embedded in deficient political, economic, social, cultural and natural ecologies. People who are forcibly displaced may seek refuge for themselves and their families within their home country (internally displaced persons) or by crossing international borders (refugees). The majority of forcibly displaced people do not cross international borders but remain within the territory of their countries.
