They also help with coastal protection in a number of ways. Coastal wetlands as storm defencesĬoastal wetlands provide a myriad of benefits, such as increasing biodiversity and water quality, and acting as nursery grounds and carbon sinks. Therefore, a natural alternative – the creation or enhancement of natural coastal wetlands – is becoming more common. Hard engineering options for storm defences, such as the construction of sea walls or groynes, tend to be expensive to build and maintain, and can have a negative impact on the landscape and environment. With sea levels predicted to rise and the severity of storms forecast to increase, many people’s homes and livelihoods are likely to come under threat in coming decades. In the UK alone, over 11 million people live near the coast.
