Perubahan Tutupan Hutan Mangrove di Pantai Timur Sumatera Utara Periode 1977-2006
ABSTRACT: Land-cover change of
mangrove forests at eastern coast of North Sumatra in Period 1977 to2006.
Mangrove is one of the world’s threatened major tropical environments.
Nevertheless,activities that contribute to this depletion continue. The main
objectives of this research wereto analyze the land cover change of mangrove
forests in eastern coastal of North Sumatrabased on previous inventory in
period 1997 to 2006 and to acquire the factors of mangrovedisturbance in the
areas. In fact, mangrove forest areas in eastern coastal of North Sumatradecreased
59.68% from 103,425 ha in 1977 to 41,700 ha in year 2006. Expansion of
aquacultureponds and extraction of timber and fuel wood were most important
factors of mangrove forest degradation in the areas. Therefore, we need to
rehabilitate the degraded mangrove forests in the area both massively and
systematically, and to prevent the remaining mangrove forests from destruction
activities.
