Applying lessons learned from the Aceh recovery from the 2004 Indian Ocean earthquake and tsunami, the government of Indonesia promoted a community-driven approach in reconstruction from the 2006 Yogyakarta earthquake. The government leveraged social capital to hasten the reconstruction process. In housing recovery for instance, both the government and NGOs introduced capacity building initiatives (e.g. socialization and on-the-spot training for the construction of earthquake-resistant housing such as "penyuluhan" and "pelatihan teknis") and advocated for use of local materials (e.g., Merantasi). The Kecamatan Development Project (KDP) and the Urban Poverty Project (UPP) are examples NGOs supporting community-driven processes.
