Assessment of green, gray and hybrid solutions for mudflow risk mitigation in the Kara Darya River Basin, the Kyrgyz Republic

Project Description
The Kyrgyz Republic, especially its southern regions like Osh and Jalal Abad, faced high climate vulnerability, with frequent landslides, flash floods, and mudflows threatening lives, infrastructure, and agriculture. Along the Kugart and Kara Ungur rivers, mudflows caused severe damage to communities and livelihoods. The Ministry of Emergency Situations (MoES) prioritized mudflow mitigation and partnered with the World Bank under the Kyrgyz Resilient Landscape Restoration Project (Kyrgyz Resiland) to implement climate-resilient solutions. The initiative focused on combining green, gray, and hybrid approaches to safeguard vulnerable areas and promote sustainable land management.

Objectives, Activities, and Results
The Joint Venture ICEM/CAIAG/HYDROC delivered technical assistance to support the design and implementation of mudflow mitigation measures in the Kara Darya Basin. The team assessed mudflow risks through hydrological modeling, physical asset surveys, and impact analysis. Potential upstream-to-downstream interventions were identified and evaluated, integrating nature-based solutions (NbS), gray infrastructure, and hybrid options. A consultation workshop refined priority actions. Investment scenarios—including baseline, gray-only, and hybrid—were analyzed through cost-benefit and multi-criteria analysis. A web-based Decision Support Tool (DST) was developed to aid land-use planning and agricultural resilience. Final outputs included policy briefs, data handover to the World Bank, and communication materials for broader stakeholder dissemination.
