Media Release: Uncertain future as sand dunes are washed away

For immediate release

“The frequency and severity of winter storms are on the increase and as sand dunes protecting infrastructure and residential properties from the ferocity of the ocean that are regularly damaged and often completely washed away, beachfront home owners have reason for concern”, says Cobus Meiring of the Garden Route Environmental Forum (GREF).

Primary and secondary sand dunes covered by indigenous vegetation are considered natural infrastructure and act as vital barriers protecting the interior from incoming high tides and wave action. As much as storms and super high tides affecting coastlines and dune systems can be considered normal, it is their frequency and increased ferocity that are posing a real and present threat to hard infrastructure and properties along beaches and low-lying areas such as lagoons, river mouths and estuaries.

Along the SA coastline homeowners with valuable beach properties are concerned about the long term future prospects of their houses. Along sections of the N2 highway in the Southern and Eastern Cape the ocean recently breached the vital road a number of times leading to road closures and damage.

Sand dunes and beaches are protected under environmental legislation and landowners are not permitted to strengthen and re- enforce washed- away dune systems in front of their properties without permission from the powers that be. Still, there is no doubt that the problems and threats of rising seas and storm surges are getting worse and there is reason for concern.

Even where permissions have been granted to protect dunes from being completely washed away those interventions are expensive and need to be comprehensive in order to be effective against the power of the sea. More often than not municipalities lack the funds to build back climate resilient infrastructure with damage incurred due to flooding, landslides and high seas.

Insurance entities are well aware of where high risk properties are located and may well amend their policies over time to be able to compensate for the high levels of exposure to the elements.

Disaster management entities monitor the impact of the ocean on high risk areas and regularly issue advisory notices when strong wind, super high tides and torrential rain all join forces in creating potential threats to coastal communities and properties.
