THE DYNAMIC OF LANDSCAPE CHANGE AT COAST AREA, IN LABAKKANG SUBDISTRICT PANGKEP REGENCY, SOUTH SULAWESI
Abstract: Development is a
changing process to improve human standard of life that strongly related to the
activities of natural resource utilization. It is frequently found that these
activities change the ecosystems and their resources. Eventually, these changes
wil l give ser ious impacts to the envi ronments. The most distinct
environmental problems are caused by resident migration to the coastal areas,
coastal developments, and land limitation. Coastal reclamation is an example of
human effort to respond to the land limitation in the coastal areas as observed
in coastal areas of Labakkang Subdistrict. Reclamation activity is doing along
the coast of Pundata Baji Village, whereas, in other villages, cutting off of
mangrove areas as an alternative land expansion is increasingly practiced by
the local communities. This Research was aimed to observe the landscape change

embankment, 933.2 ha rice field, and 582.0 ha open land. In 2000, there are
218.3 ha mangrove vegetation, 2,848.1 ha embankment, and 3,579.2 ha rice field.
In 2005, it has 121.4 ha mangrove vegetation, 3,762.6 ha embankment, and
2,306.2 ha rice field. In 2010, it is found 48.9 ha mangrove vegetation,
