Private island
Southeast Asia has numerous islands, with Indonesia being an archipelago of 17,000 islands and the Philippines having around 7,100. Real estate laws restrict foreigners' ability to buy property in the geographical area, and many islands either have unclear ownership rights or are already settled. Private islands that are available in Southeast Asia's real estate market are also prohibitively costly due to being in high demand by hotel developers. Developments address these difficulties by selling private islands that have villas and neighbor islands that have high-end hotels; the proximity keeps costs of habitation down.
Environment of Indonesia
Climate change is having and will have further serious impact in the form of rising sea levels. As Indonesia is the world’s largest archipelago state, at current rates, rising sea levels will result in 42 million Indonesian households over 2000 islands being at risk of submersion by the middle of this century. Over 60% of Indonesia’s population live in low-lying coastal areas, including Jakarta, which is particularly at risk, as 40% of the city is below sea-level and is rapidly subsiding, putting a huge number of people at risk of displacement.
