The Integrated Water Resources Management and Ecosystem-based Adaptation (IWRM-EbA) Project is designed to assist the government of Lao PDR in managing land and water resources to build climate resilience against floods and droughts in the Xe Bang Hieng River Basin and Luang Prabang City. This specific Environmental and Social Impact Assessment (ESIA) report focuses on the project's interventions within Savannakhet Province, an essential agricultural region highly vulnerable to extreme hydrological events. Implemented by the Department of Water Resources of the Ministry of Agriculture and Environment, the initiative combines ecosystem-based adaptation with protective infrastructure to safeguard marginalized riverine communities from the intensifying impacts of climate change.

The assessment evaluates the potential environmental and social risks associated with Component 2 of the project, which includes the construction of small-scale protective infrastructures across ten target villages in five districts of Savannakhet Province. These physical interventions involve the development of flood evacuation shelters, riverbank stabilization works, wetland modifications, community pond improvements, gravity-fed water supplies, and flood protection levees. Additionally, the report examines conservation activities such as natural regeneration, enrichment planting, and forest boundary management within the protected forests and Ramsar sites of the river basin.  A mixed-method approach was employed for the ESIA, utilizing both qualitative and quantitative data gathered from site visits, stakeholder consultations, and secondary study reports.

The findings indicate that while the project will deliver significant positive impacts by decreasing flood risks and improving water availability, it poses low to moderate environmental and social risks primarily during the pre-construction and construction phases. Anticipated minor negative impacts include localized reductions in ambient air quality due to dust, negligible soil erosion, elevated noise from heavy machinery, and small-scale land requirements. The assessment confirms that direct impacts on critical biodiversity and habitats are unlikely since the construction activities are generally not located in sensitive zones of ecological concern.  

To ensure that these localized impacts are appropriately managed, the report outlines a comprehensive Environmental and Social Management and Monitoring Plan (ESMMP) that mandates strict mitigation measures for contractors. These protective measures include the mandatory development of a Construction Environmental Management Plan (CEMP), proper hazardous and solid waste handling, traffic management, and robust occupational health and safety protocols. Furthermore, the project emphasizes continuous stakeholder engagement and the implementation of a clear grievance redress mechanism, ensuring that local communities, ethnic groups, and vulnerable populations remain actively involved, consulted, and protected throughout the entire project lifecycle.
