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.
Protected areas of Indonesia
There are 50 national parks in Indonesia, of which 9 are predominantly marine.
Of these 6 are World Heritage Sites, such as the Tropical Rainforest Heritage of Sumatra that includes three parks. Seven national parks are part of the World Network of Biosphere Reserves and 5 are wetlands of international importance under the Ramsar convention. As of 2012 Indonesia had over 100 marine protected areas covering an area of 15.7 million ha, of which 32 where managed by the Ministry of Forestry while the rest where managed by local governments. In 2009 the president Susilo Bambang Yudhoyono declared a target of reaching 20 million hectares by 2020. In 2010 Indonesia also set out a longer term target to further increase the coverage of its marine protected areas to 10% of its territorial waters, or 31 million hectares.
