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 disaster-prone 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.
