For starters, it’s not because of the refugees themselves, or their decision to flee. In fact, the biggest problem of the refugee crisis is usually the needs of refugees themselves. Escaping persecution or any other threat is just the beginning of their story, and the challenges faced in displacement range from language barriers and not being able to legally work, to living in substandard conditions (often informal tented settlements), to facing gender-based violence, sexual assault, and post-traumatic stress.
Part of the problem with the current crisis is one of capacity: Providing the bare necessities to nearly 30 million refugees and ensuring protection of their rights is, to say the least, a challenge. Further complicating this is that many refugees are hosted in countries that are also prone to conflict, violence and insecurity, making supplies and support that much harder to get to the right people.
Along these lines, host communities also face pressure. Many of the largest communities for refugees are in neighbouring countries (of the twelve largest host communities at the end of 2021, only one—Germany—was in Europe, the rest were in Africa, the Middle East and Asia). Temporary displacement is one thing, but the protracted nature of most conflicts now means that host communities with limited resources can be left with refugee communities for years, if not decades.
