The relocation of the Indonesian Capital City (IKN) to East Kalimantan faces significant challenges, one of which is environmental sustainability.
The IKN development has the potential to damage biodiversity in the region.
The biodiversity assets of IKN are documented in the research article "Analysis of the Forest City Concept in the National Capital Integrated Development Plan" in the *Bappenas Working Papers* journal (Volume 4 No. 1, 2021), written by a team of planners and experts from the Ministry of National Development Planning/Bappenas: Dadang Jainal Mutaqin, Muhajah Babny Muslim, and Nur Gygiawati Rahayu.
"Based on current conditions, 59.5 percent of the IKN area is forested, consisting of conservation forests, protected forests, and production forests," stated Dadang et al.
"Furthermore, IKN also includes areas identified as high conservation value areas, which are areas with rare ecosystems serving as wildlife habitats and river buffer zones," they continued.
According to data from the Ministry of Environment and Forestry (KLHK) cited by Dadang et al., the IKN region and its surroundings possess biodiversity comprising 527 plant species, 180 bird species, over 100 mammal species, and 25 herpetofauna species.
Herpetofauna are reptiles and amphibians, playing a crucial role in the food chain and serving as bioindicators.
Bioindicators are organisms sensitive to pollution or signs of environmental change, making their presence a benchmark for ecosystem quality.
"The IKN region and its surroundings are part of Kalimantan Island, one of Indonesia's main biodiversity hotspots, characterized by a variety of animal and plant species, including several protected or important species," said Dadang et al.
"The survival of these animals and plants is threatened by potential habitat degradation," they continued.
Considering this, the planning team and experts from the Ministry of National Development Planning/Bappenas recommend that IKN development adopt a forest city concept based on the following six principles:
1. Conservation of natural resources and wildlife habitats;
2. Connection with nature;
3. Low-carbon development;
4. Adequate water resources;
5. Controlled development; and
6. Community involvement.
"Each of these principles is further elaborated based on criteria and indicators to ensure that each principle is met in the IKN development planning," said Dadang et al.
"The application of this forest city concept is not limited to the city context but is also expected to be integrated with the surrounding areas, especially to support the sustainability of forests and the environment in general," they continued.
