01Background
The exploitation of Valera heavy sands presented significant environmental challenges for the coastal zone and water resources.
A rigorous ESIA was essential for project compliance and social acceptability.
02Challenges
Reconciling development with preservation required rigorous assessment of impacts on ecosystems and resources.
Regulatory compliance and project social acceptability were central to the approach.
03Mission Objectives
- Characterize the geological and hydrogeological context
- Assess the project's impact on coastal erosion
- Assess the impact on water resources
- Formulate mitigation measures
04Services Delivered by EAU-GEF
- Field geological investigations
- Coastal erosion impact study
- Water resources impact study
- Environmental and Social Management Plan
05Approach & Methodology
The methodology combined field investigations, analyses and structured risk assessment, culminating in a management plan.
Each conclusion was supported by measured data to ensure diagnostic robustness.
06Results & Added Value
The study equipped the contracting authority with a diagnostic and operational recommendations to manage impacts.
It strengthens EAU-GEF's role in sensitive environmental issues.
