3.2 National Spatial Plan
The regional spatial plan which has been ratified as a government regulation no 26/2008 and revised into a government regulation no 13/2017 states that the strategy for controlling the development of cultivation activities so as not to exceed the carrying capacity and capacity of the environment includes: a. limit and control the development of cultivation activities taking place in disasterprone areas and high risk of disaster areas as well to minimize potential disaster events and potential losses due to disasters and climate change; b. developing metropolitan cities and big cities by optimizing the use of space vertically and compactly; c. develop green open space with an area of at least 30% (thirty percent) of the urban area; d. limiting the development of built-up areas in metropolitan areas and big cities to maintain the level of service for infrastructure and facilities in urban areas and maintain the function of surrounding rural areas; e. develop cultivation activities that can maintain the existence of small islands; f. limiting and controlling cultivation activities in locations that have high conservation value; g. determine damaged and polluted locations to be restored; h. controlling the balance of carrying capacity and environmental capacity in mediumsized cities as urban areas that support the flow of urbanization from rural to urban areas; i. controlling changes in the designation of forest areas for the allocation of development land for the non-forestry sector by considering environmental strength, the character of natural resources, ecological functions, and the need for land for sustainable development; j. encourage the development of community forests to support adequate forest cover, especially for watershed areas or islands with less than 30% (thirty percent) forest cover; and k. develop cultivation activities by taking into account the bio-ecoregion which is a landscape located within one or more watersheds.
