A side event on strengthening synergies among the Rio Conventions through integrated land-use planning and investment was held during UNCCD COP17. The event presented emerging findings from a study exploring how Mongolia’s commitments on land degradation, climate change, biodiversity conservation and food security can be aligned through an integrated land-use planning approach and translated into investment-ready actions. The study demonstrates that coordinated planning can help identify priority areas for restoration and sustainable land management, improve policy and institutional coherence, reduce duplication, and direct limited financial resources toward areas where they can generate the greatest environmental, social and economic benefits. Discussions also highlighted the importance of combining scientific evidence and economic analysis with stakeholder participation, local knowledge and practical implementation mechanisms. This approach can support more inclusive, efficient and finance-ready investments while strengthening climate resilience, biodiversity conservation, food and water security, and rural livelihoods. Mongolian experience provides a promising example of how Rio Convention commitments can be brought together at the landscape level and linked with concrete investment and implementation. The approach could also offer useful lessons for other dryland and rangeland countries facing similar challenges.
