A migrant crisis is a difficult or dangerous situation that arises due to the movements of large groups of immigrants (displaced people, refugees or asylum seekers) in the receiving state (destination country). Migrants are often escaping from conditions which negatively affected them (whether to do with security, the economy, politics or society) in the country of origin (departure). The "crisis" is not the amount of refugees, but the system's failure to respond in an orderly way to the government's legal obligations towards them.[1] Some notable crises are; European migrant crisis, English Channel migrant crisis and World War II evacuation and expulsion.
A refugee crisis refers to a movement of "large" groups of displaced people, and may or may not involve a migrant crisis. The US government's legal obligations inadvertently created the 2014 American immigration crisis. The crisis developed because of unaccompanied children[2] who do not have a legal guardian to provide physical custody (USA ratified the Convention on the Rights of the Child), and care quickly overwhelmed the "local border patrols" creating a migrant crisis.[3] Push-Pull view: The "refugee crisis" is a humanitarian one for those adopting the "Push" factors as main cause, while they acknowledge that reasons for migration may be mixed, even the refugees as weapons. For those focusing on "Pull" factors, the "migration crisis" has its roots in border enforcement policies (Immigration system) that were perceived as not sufficiently strict and the need for cheap workers for US business (family separation policy), severe (Operation Streamline), or careful (catch & release) by potential migrants.[4] Compared to refugee crisis (refugee is a refugee), migrant crises also have a separate or distinguish between the “deserving” refugee from the “undeserving” migrant and play into fear of cultural, religious, and ethnic difference in the midst of increasing intense, excessive, and persistent worry and fear about everyday situations and lacking in predictability, job security, material or psychological welfare for many in Europe (such in closure of Green Borders).[5]
"Migrant crisis management" involves dealing with issues ("immigration system", "resource management", etc.) before, during, and after they have occurred. 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 needed for solving migratory issues of the world.[6]
