Study on Natural Risks in the Centre-Artibonite Loop and Risk Mapping for the Communes - Annex 6: Commune of St-Raphaël
Summary — This annex focuses on natural risk assessment and mapping for St-Raphaël commune as part of a broader regional development program for the Centre-Artibonite loop. The study analyzes flood, drought, seismic, and landslide hazards to inform safe urban development planning.
Key Findings
- St-Raphaël faces multiple natural hazards including flooding from Bouyaha river and lateral ravines.
- Drought conditions affect both urban and rural water supply systems and rainfed agriculture.
- Seismic risks are present due to geological conditions and proximity to fault systems.
- Landslide and erosion hazards threaten settlements, particularly in northern areas of the town.
- Risk mapping is essential for guiding safe urban development in the Centre-Artibonite corridor.
Full Description
This technical annex is part of a comprehensive natural risk study for the Centre-Artibonite loop region, conducted following the 2010 earthquake as part of Haiti's decentralization and regional development strategy. The study aims to identify and map natural hazards to ensure sustainable development and protect future infrastructure investments in the region.
The document specifically examines St-Raphaël commune, analyzing four main types of natural hazards: flooding (particularly from the Bouyaha river and lateral ravines), drought conditions affecting water supply and agriculture, seismic risks, and landslide/erosion hazards. The methodology includes field reconnaissance, community consultations, and technical analysis to produce detailed risk maps.
The study is conducted by ARTELIA Eau & Environnement for the Ministry of Economy and Finance, with support from the World Bank. It forms part of a broader regional development program aimed at creating an economic corridor linking the Centre and Artibonite departments, promoting economic growth while ensuring disaster risk reduction.
The findings will inform urban planning decisions and infrastructure development to avoid high-risk areas or implement appropriate mitigation measures, contributing to the overall resilience of the Centre-Artibonite development corridor.
