The Coastal Zone Management in adapting to climate change:

Manterawu Island is one of the outer small islands located in North Sulawesi Province. This island plays a very important role, especially related with the country borderline. Based on the census held in 2006, the number of people who lived in this small island is more than 600 people. Like other small islands, Manterawu Island has various marine ecosystems, such as coral reefs, mangrove, and sea grass. Unfortunately, the utilization of those resources seems to be neglected. Those ecosystems are very essential in term of small islands management and need appropriate action to take into account.

Currently, climate change turns out to be one of the important environmental issues. Furthermore this phenomenon can cause adverse impacts for small islands related with those coastal zones and marine ecosystems, include the rising sea level, extreme weather events, fresh water scarcity, and coral bleaching. Small islands are among the most susceptible to climate change impacts; therefore it needs a comprehensive coastal zone management strategy that applicable to small islands in adapting to climate change as well.

This research try to estimate the area of Manterawu Island that will be inundated because of rising sea level, describe the main problem in coastal zone management related to climate change and propose some policy scenarios to overcome those problems, such as build the hard and soft structures, relocate the population to another safe areas, and integrated coastal zone spatial planning implementation. High resolution imagery (Quickbird) was used in this research to obtain the land use classification, while the contour data was used to build 3D inundation model. Later on, the result of this research and recommendations could be used by local government, relevant institutions, and all stakeholders, as an input in developing and implementing the small island coastal zone management in adapting to climate change.
