Credit unions played an important role in post-disaster housing reconstruction in Sri Lanka after the 2004 tsunami. As locally owned and governed cooperative financial institutions, credit unions were able to [1] choose vulnerable families to receive housing, [2] involve members in the construction process to address issues of conflict and corruption, and [3] design culturally appropriate housing that addressed water, sanitation, and land ownership challenges. While credit unions leveraged their local knowledge and networks, oversight from an objective third party was still needed to ensure transparency, quality, and adherence to realistic timelines during the reconstruction process.
