Palestine. Syria. Thailand. Chad. Pakistan. The whole world. War, political unrest, floods, earthquakes, fire... According to the UN refugee agency, there are around 45.2 million people around the world who have been evicted from their homes. Of these, approximately 15.4 million are considered refugees - people who are forced to flee from their home country due to war, fear of persecution or national disasters and accommodated temporary in often inadequate structures with limited access to basic human needs. Refugee camps are seen and conceived as temporary architecture. Mostly, they are constructed of tents and shelter, so to allow quick and easy installation, and to respond to immediate emergencies. Because of their short-term form of architecture, they are not built to last. But the reality is different. The refugee camps are rarely of short duration - the average life-span of a refugee camp is 7 to 17 years (reports vary), and often longer. Increasingly, these camps become places where people are born and die while waiting to return home. Through a more detailed analysis of four existing refugee-camps the differences and particularities of each of these space are shown. Special focus will be put on more than 20 years of the existing collective centers for displaced persons in Bosnia and Herzegovina. Pragmatic and sustainable ideas for housing, infrastructure, education and employment will be proposed, encouraging communities to be active participants in rebuilding their lives.
