"Migrant crisis management" involves dealing with issues ("immigration system", "resource management", etc.) before, during, and after they have occurred. This is an area which Global Crisis Centre of PricewaterhouseCoopers works by developing outlines on roles, opportunities and challenges faced by governments and private sector actors in addressing migration crisis through the 'push' and 'pull' factors that influence migration. According to Global Crisis Centre, migrant crisis management is shaped using the definitions and responsibilities outlined in the UN's Convention Relating to the Status of Refugees and subsequent Protocol Relating to the Status of Refugees and international solidarity and burden-sharing with collaboration, communication and information dissemination, which are absolutely necessary for solving migratory issues of the world.
