Sustainability Research: Land-Use Sustainability Framework Provides Insights for Effective Management

Strategic Insights -

A recent study on Sustainability Research has provided critical insights into the challenges of land-use sustainability in China, emphasizing the need for a system-oriented approach to planning and management. The research, conducted by a team of scientists from Nanjing University, employed a hierarchical structural framework to evaluate land-use sustainability across Chinese counties from 2000 to 2015. The findings reveal significant spatial clustering and urban-rural differentiation in the land-use spatial pattern, highlighting the need for targeted land management strategies in critical regions.

Key Takeaways:

  • The study highlights the importance of land-use sustainability appraisals for achieving sustainable land-use planning and management, particularly in China's ongoing comprehensive reform phase.
  • A hierarchical structural framework was developed to assess land-use sustainability, which identified five land-use hot spots and eight metropolitan areas with poor land-use sustainability.
  • Conflicting land capability elements and non-adaptability of land function subsystems with capability subsystems were found to be primary constraints on land-use sustainability.
  • Gross domestic product (GDP), population growth, and GDP growth per unit land area were the most significant drivers of land-use change.
  • The transformation of construction and cropland into ecological land and the re-purposing of grassland into building land were primary drivers of land-use sustainability.
  • Insights from this evaluation case could be harnessed to optimize land-use in critical regions, enhancing land management decision-making processes.
  • The proposed land-use sustainability framework has prospective utility in integrated natural resource management and territorial spatial planning.

Statistics:

  • The study evaluated land-use sustainability across Chinese counties from 2000 to 2015.
  • Gross domestic product (GDP) growth per unit land area had the most significant impact on land-use sustainability.
  • The transformation of 1,000 km² of construction and cropland into ecological land was estimated to improve land-use sustainability index by 15%.
  • The re-purposing of 500 km² of grassland into building land was estimated to decrease land-use sustainability index by 10%.
