NT11. Enhancing Urban Biodiversity

11 Urban blue and green space

Ensure that more people can benefit from urban parks and green and blue spaces by increasing the area, connectivity and accessibility of such spaces, and assess and manage integrity of urban ecosystems.

Action plan tasks

  • 11-1Expanding the coverage of urban green areas
    • Expanding the coverage of urban green areas

    • ㅇ Expand the area of accessible urban forests in neighborhoods from 54,354 hectares in 2020 to 70,700 hectares in 2027 and create forests and forest trails on idle and abandoned lands such as unused railroad and train station areas and former military bases.
      - The number of urban forests established in response to climate change is expected to increase from 207 in 2021 to 1,200 in 2027, while the number of “wind path forests” designed to circulate clean air in urban areas will jump from 17 in 2021 to 25 in 2027.

      ㅇ Increase the number of urban ecological axis restoration projects to 50 in order to expand ecological spaces in everyday life and gradually restore, by 2050, all disconnected and damaged urban areas.

      ㅇ To facilitate the greening of rooftops and walls in urban areas, conduct a pilot project for public buildings from 2027 to 2029 after analyzing the effectiveness of greening, and expand it to private buildings by 2030. Moreover, restore ecosystems by tapping into the Ecosystem Conservation Fund and continue to expand micro ecosystems such as ecological playgrounds.

      ㅇ Continue to increase street trees and waterfront forests to strengthen the urban blue-green networks.
    • Increasing the coverage of urban blue spaces

    • ㅇ Launch a project to build eco-friendly, water-friendly cities by utilizing natural ecosystems and waterfront spaces around national rivers.

      ㅇ Review, by 2024, the effectiveness of the project to create ecological reservoirs for flood prevention such as vegetated wetlands in ecological parks and green restoration sites, and implement the project in 2026 after conducting consultations with local governments in 2025.
    • Setting standards for the management of urban green spaces

    • ㅇ Apply the 3-30-300 rule* to each local government in managing urban green spaces, boosting connectivity and accessibility.
      * The 3-30-300 rule requires that at least 3 well-maintained trees are visible from houses; urban tree canopy covers at least 30% of the city’s land area, and the nearest public green space is within 300 meters.

      ㅇ Amend the Biodiversity Act to address regional disparities by setting quantitative targets for green and blue spaces when developing the LBSAP.
  • 11-2Assess the health of urban ecosystems and enhance their qualitative value
    • Assessing the health of urban ecosystems

    • ㅇ Unify the methods of evaluation and develop relevant indicators to measure the area of green cover, the percentage of impermeable layers, the status of biodiversity and other related factors by 2026 with a view to assessing the health of urban ecosystems in each city.

      ㅇ Evaluate the ecological functions and health of urban areas by linking regional urban ecological maps, land use maps, land cover maps and vegetation maps to indicators from 2027.

      ㅇ Introduce a procedure for reviewing and supplementing urban ecological maps by specialized organizations to improve the accuracy of the maps, and build capacity to create and utilize the maps through regular training for each region.
    • Enhancing the qualitative value of urban ecosystems based on health assessments

    • ㅇ Establish conservation and enhancement measures for healthy areas by taking into account a variety of factors such as urban forests, rivers and neighboring ecosystems after classifying urban ecosystems into healthy, conserved and degraded areas based on health assessments. Manage the degraded areas in a customized manner by proposing restoration plans in consideration of local industrial, agricultural and residential characteristics.

      ㅇ Prepare urban forest management indicators to ensure the systematic management of urban forests, and have the head of the local government assess the health of urban forests under his/her jurisdiction using the urban forest management indicators every five years. For local governments with poor assessment results, reflect improvement measures in the 10-Year Urban Forest Creation and Management Plan for continued monitoring of management quality.
    • Analyzing urban ecosystem connectivity and accessibility

    • ㅇ Develop indicators of connectivity and accessibility for green and blue spaces and start monitoring them in 2025.

      ㅇ Analyze the distribution characteristics and interconnectivity of urban forests and forest landscapes as well as the diversity and spatial characteristics of vegetation landscapes within urban forests.
