A technical assessment will inform the deployment of hard and nature-based solutions for reducing coastal erosion in Nauru. Financial support is required to fund the assessment, which will cost approximately USD 800,000. The target for completing the assessment is 2021. Adaptation Co-Benefits. Increased resilience of housing and critical infrastructure to climate change impacts. Increased resilience of coastal zone ecosystems and biodiversity. SDGs Advanced by Nauru’s NDC to Reducing Coastal Erosion. Water security will be increased by reducing salt water intrusion into freshwater lenses. Climate action will be enhanced by significantly mitigating the near- and medium-term impact of sea level rise. The resilience of coastal infrastructure will be improved by reducing the risk of storm surge and coastal flooding.
