Abstract
The vulnerability is the sequence of condition that determines whether a hazard will cause disaster or not. The small islands are easily affected by the climate change effects. The small islands are particularly vulnerable to the projected of climate change effects. Harapan and Kelapa Islands is a small island in the Thousand Islands Region, DKI Jakarta Province. This study aims to analyze of climate change effects on social, economic, and environmental on small islands. This study using key indicators consist of social, economic, environment, and climate change. The methods applied in this research is GIS and system dynamics or called by spatial dynamics. The result showed that the area of study categorized as the vulnerable area to the climate change effects, this is due to the increasing sea level rise and rainfall, the growing population number and density, and the expanding built area. Therefore, the need for disaster mitigation and adaptation efforts on the climate change effects.
Highlights
Disaster mitigation of climate change effects is one of the ways that small islands can be sustainable
In addition to having large numbers, small islands are generally limited to terrestrial natural resources but have enormous marine resources
The area of study within 10 years is always increasing, this can be seen in Table 1, the area increased in both islands with details of Island of Harapan in the period of 10 years increased by 1.52 Harapan Island (Ha), while for Kelapa Island within 10 years increased by 2.41 Ha
Summary
Disaster mitigation of climate change effects is one of the ways that small islands can be sustainable. Coastal areas and small islands are rich in diversity of natural resources, such as fisheries, mangrove forests, coral reefs, petroleum, mining materials, and gases and minerals [1]. In addition to having large numbers, small islands are generally limited to terrestrial natural resources but have enormous marine resources. Small Island has a characteristic effect due to the small size of the land as well as isolated (insular) of the big island (mainland) [6]. There are four typical constraints of small islands to be considered in the economic assessment of small island resources, ie smallness, isolation, dependence and vulnerability [2]. Small islands if well managed can sustainable
