On 26 December 2004 the biggest earthquake in 40 years occured between the Australian plate and Eurasian plate in the Indian Ocean. The quake triggered a tsunami (series of large waves) that spread out to several coastal cities in Nangroe Aceh Darussalam Province, including its Capital, Banda Aceh City. In this region over 120 000 lives have lost and 1 million is homeless. Based on analysis remote sensing data (preliminary report of LAPAN), more than 120 000 hm2 of land are damaged. In Banda Aceh City, the changes of fishponds, residential areas and conservation areas (mangrove and other forest) were dominated the land use/cover changes. These three land use/covers were decreased about 61.5%, 57.8% and 77.6% from the former respectively. The central government is preparing a new coastal spatial planning which promotes a buffer zone (about 2 km from the seashore) in the formerly most dense areas. Many groups of coastal communities and NGOs are asking for the involvement of local community in decision making process.
In order to select and adopt the best use of the land, the coastal spatial zoning in the aftermath of the tsunami should determine several basic issues. This study is focusing on Banda Aceh City as center of many socio-economic activities. This study examines the changes of land use-cover (including physical damages) due to the impact of tsunami especially for agriculture and settlement uses and analyzes the typology of affected villages based on land use/cover changes and socioeconomic aspects. Moreover, this study examines the government spatial planning in the aftermath of tsunami and the local people needs to seek some sustainable options for the future spatial arrangements.
