Refugee Shelter That Becomes Permanent Dignified Housing

The UNHCR definition of a refugee situation as "prolonged" is three years. By that definition, the majority of current refugee situations are prolonged. The median duration of displacement for the world's refugees has been rising steadily since the 1990s and crossed the ten-year mark in the 2010s. The Sahrawi refugees in Algeria have been in the same camps since 1975 — half a century. The Palestinian refugee situation began in 1948. Somali refugees have been in Dadaab camp in Kenya since 1991. These are not temporary situations with temporary shelter needs. They are communities that have built societies in the space that emergency shelter systems created, around and despite those systems.

The physical consequences of designing shelter for two years and occupying it for twenty are well documented. Plastic sheeting used as roofing material has a UV-degradation lifespan of two to five years in tropical sunlight. UNHCR standard tarpaulins carry a manufacturer-rated lifespan of eighteen months. Prefabricated shelter units of polyurethane, cardboard, or lightweight metal typically last three to seven years without significant maintenance investment. The regular replacement cycle for a camp population of 500,000 people, maintained over twenty years with these materials, costs more than the construction of permanent earthen housing would have cost at the outset.

The cost comparison is documented. A 2016 analysis by Shelter Centre comparing emergency shelter approaches across multiple contexts found that the lifetime cost of providing and maintaining standard emergency shelter over a ten-year period — including replacement cycles, transportation, and logistics — consistently exceeded the construction cost of permanent earthen structures by a factor of two to five. The IKEA Foundation's Better Shelter unit, a more durable prefabricated plastic shelter widely adopted since 2015, costs approximately $1,150 per unit with a rated lifespan of three years — which implies a twenty-year cost of approximately $7,700 per household in materials alone, not including logistics. A compressed earth block structure of equivalent floor area, built by trained community members from local materials, costs approximately $2,000 to $4,000 in materials and supervision in most refugee-hosting countries, with a lifespan measured in decades.

The specific performance advantages of earthen construction in humanitarian contexts go beyond cost. In hot arid contexts — which include the majority of the world's large refugee camps in the Sahel, the Horn of Africa, the Middle East, and parts of South Asia — thermal mass is critical. Daytime temperatures in canvas tents and plastic shelters in these environments regularly exceed 50°C, producing heat stress that is directly responsible for deaths, particularly among children and the elderly. Earthen walls with sufficient thickness (300mm or more of rammed earth or 200mm of compressed earth block) maintain interior temperatures 10 to 20°C below peak ambient temperature without any mechanical cooling — a performance that cannot be replicated by any lightweight temporary shelter material at any cost.

In cold contexts — Eastern Europe, Central Asia, highland Africa — the insulating properties of thick earthen walls and earthen roof systems provide equivalent performance advantages against winter cold, replacing the heating fuel requirements that constitute a major expenditure and safety risk in cold-climate refugee camps.

Structural durability under seismic loading is relevant in many refugee-hosting regions including Turkey, Jordan, Ethiopia, Pakistan, and Greece. Well-designed confined adobe or compressed earth block construction using techniques developed through engineering research can provide adequate seismic resistance in moderate seismic zones, outperforming both tents and lightweight prefabricated systems that provide essentially no seismic resistance.

Psychological and social benefits, while harder to quantify, are documented consistently in research on refugee shelter. Studies by the IRC, by academic researchers at University College London, and by UNHCR's own shelter unit have found that residents in permanent or semi-permanent structures report significantly higher levels of security, dignity, and wellbeing than residents in temporary shelters, controlling for other factors. This is not a soft finding. Mental health outcomes are among the strongest predictors of long-term economic recovery and social integration following displacement.

The prohibition on permanent construction in refugee settlements derives from the 1951 Refugee Convention's framework, which defines refugee status as temporary and conditions on which return to country of origin is expected. The legal logic holds that constructing permanent structures signals acceptance of permanent displacement, potentially undermining diplomatic efforts for repatriation and legally complicating eventual camp closure.

This policy logic has been increasingly challenged both empirically and normatively. Empirically, the non-permanence doctrine has not accelerated repatriation in any documented case — refugee situations that have been resolved have been resolved through political developments, not through the inadequacy of shelter. Normatively, the argument that refugees should be housed poorly as an incentive toward return has been criticized as a form of coercion that violates the Convention's own provisions regarding the rights of refugees to dignified treatment.

The practical effect of the non-permanence doctrine has been to prevent the construction of structures that would be safer, healthier, more comfortable, and less expensive to maintain than the approved alternatives, solely to preserve a political signal that has no demonstrated effect on actual outcomes. This is a substantial cost imposed on a vulnerable population for a non-existent benefit.

Several donors and host governments have begun to relax this constraint. Uganda's refugee policy, considered among the world's most progressive, allows refugees to build permanent structures and engage in agriculture. Several projects in Uganda have used compressed earth block construction with UNHCR and NGO technical support, producing structures comparable in quality to local host community housing and at similar cost. The political argument against permanence is harder to maintain when the host government's own policy accepts it.

Jordan, Za'atari Camp: Za'atari opened in 2012 and within two years became Jordan's fourth-largest city, housing 150,000 Syrian refugees. The initial tent phase gave way to caravan units that have been inhabited far beyond their intended duration. Residents have modified, extended, and connected the caravans using local materials, creating neighborhoods with market streets, schools, and social infrastructure not designed by any external planner. The spontaneous construction that residents have undertaken — using salvaged materials, concrete block purchased with remittances, earthen plasters on interior walls — demonstrates the same dynamic documented in every other informal settlement context: given any security of tenure and access to materials, people build.

A 2018 pilot project in Za'atari tested compressed earth block construction of communal facilities using a block-making machine operated by trained Syrian refugees. The blocks were produced from sand and gravel available on-site, stabilized with 8 percent cement, and used to construct a community center and ablution facilities. Production costs were approximately 60 percent of equivalent commercial block costs. The trained block-producers subsequently established a small informal manufacturing enterprise selling blocks to other residents for residential improvements.

Ethiopia, Dollo Ado: The Dollo Ado refugee complex in southeastern Ethiopia hosts approximately 220,000 Somali refugees in five camps that have existed since 2009. A Norwegian Refugee Council program beginning in 2015 tested earthen construction of transitional shelter using compressed earth blocks produced on-site by community construction teams. The program trained 120 refugees as earth block producers and construction supervisors over a six-month period. By 2018, over 400 transitional shelter units had been constructed using the trained teams, at a cost 35 percent below UNHCR standard transitional shelter and with significantly better thermal performance. The trained supervisors subsequently formed a construction cooperative that contracts services both within and beyond the camp.

Pakistan, Afghan Refugees: The largest protracted refugee population in the world — at various points over 3 million Afghans in Pakistan — has been largely housed in informal extensions to Pakistani villages and in designated refugee villages where earthen construction was the norm from the outset, using techniques brought from Afghanistan or learned from Pakistani neighbors. The Afghan refugee villages in the Northwest Frontier Province developed over forty years into permanent-looking communities with substantial earthen construction that was never designed by any international organization and was funded primarily by refugee households themselves, through income from labor and small enterprise. The durability of these structures has significantly outlasted the "temporary" status that justified the original camp creation.

The practical design principles for refugee shelter that can serve as permanent housing if needed, while remaining appropriate for emergency deployment, are not technically complex. They center on three requirements:

First, the primary structural and envelope materials must have a design lifespan of at minimum twenty years, to match the actual statistical duration of refugee situations. This rules out plastic sheeting, fabric tenting, and most prefabricated lightweight systems as primary structural elements. It is consistent with earthen masonry, timber frame, bamboo structure, and lime-stabilized block.

Second, the construction process must include skills transfer to future inhabitants. Shelter constructed for refugees by external contractors provides housing but not knowledge. Shelter constructed by trained refugees provides both housing and productive skills that have labor market value within the camp, in host communities, and eventually in post-conflict reconstruction contexts. The investment in training is not a cost — it is a productive output.

Third, the tenure framework must provide sufficient security for investment. This does not require freehold title. It requires an explicit commitment from the host government and UNHCR that structures built to approved standards will not be demolished without adequate compensation and process. This is a policy commitment, not a financial one, and it costs nothing to make.

These three principles — durable materials, skills transfer, tenure security — constitute a design standard for humanitarian shelter that is achievable within existing cost envelopes and that would dramatically improve outcomes for the world's displaced populations over the decades-long timescales their displacement actually spans.
