Coastal zones

Context

The coastal zone is one of the nation's greatest environmental and economic assets of Liberia. However, the evolution of coastline variations is considered as one of the most dynamic processes affecting this area. Liberia has initiated its Technology Needs Assessment (TNA) in 2019. Integrated Coastal Zone Management has been identified as one of the three and the most important technologies priorities for the country along with Flood Early Warning System and Armour or Rock Revetment.

• Nationally Determined Contribution to develop new integrated climate services and information systems, for continuous monitoring and risk mapping. Furthermore, by 2030, have developed new early warning systems and new hydrometeorological insurances, within the disaster risk reduction framework for the agricultural, coastal and health sectors, and for flood sensitive urban areas, infrastructure and other vulnerable regions. 

Context

Seawalls are hard engineered structures with a primary function to prevent further erosion of the shoreline. They are built parallel to the shore and aim to hold or prevent sliding of the soil, while providing protection from wave action (UNFCCC, 1999). Although their primary function is erosion reduction, they have a secondary function as coastal flood defences.

The physical form of these structures is highly variable; seawalls can be vertical or sloping and constructed from a wide variety of materials. They may also be referred to as revetments.
