Summary

This parallel session explored the synergy approach to addressing the triple crisis—climate change, biodiversity loss, and pollution—by transitioning from conventional, "grey" concrete infrastructure to multifunctional green infrastructure. The speakers emphasised that nature-based solutions are essential for solving multiple social, economic and environmental challenges simultaneously rather than in silos.

The first speaker presented research on optimising renewable energy projects through scientific data, ensuring they align with biodiversity goals to achieve nature-positive outcomes rather than causing ecological damage.

The second speaker showcased a 25-year-old "Five Trees" (Gohon no Ki) project. This initiative integrates native plant species into residential gardens, successfully fostering local ecosystems and significantly improving human well-being through data-driven design.

The third speaker highlighted the power of "small-scale nature restoration." By leveraging traditional techniques and engaging local communities, these manageable, low-cost projects effectively balance flood control, habitat restoration and local tourism.

The session concluded that a successful transition to a nature-positive society requires collaborative, multisectoral mechanisms where governments, businesses, researchers and citizens co-create solutions. By aligning interests and using scientific evidence, we can turn nature conservation into a foundational pillar of sustainable regional development.

Key messages
  • Synergy Over Silos: Solving the triple crisis requires a synergy (nexus) approach and collaboration among diverse stakeholders. Implementing renewable energy requires a nexus approach to ensure projects align with biodiversity conservation.
  • Strategic Biodiversity Restoration: Businesses play a critical role by integrating nature into their core operations. By utilising native species in residential landscaping and using data-driven tools, housing companies can transform private spaces into ecological corridors that boost local biodiversity and improve human well-being.
  • Empowering Local Action: Small-scale, community-led projects using traditional, low-impact techniques offer effective, cost-efficient and scalable solutions for flood control and habitat restoration, turning nature conservation into a foundational element of sustainable regional development.
