Coastal Erosion: A Global Threat

Understanding Coastal Erosion

Coastal erosion, a pressing environmental issue, is the gradual degradation and displacement of land along coastlines. This phenomenon results from the persistent action of waves and other coastal processes, causing the loss of beaches, cliffs, and dunes.

Causes of Coastal Erosion

Natural Processes

Coastal erosion is primarily driven by natural processes such as wave action, tidal currents, and sediment transport. As waves crash against the shoreline, they erode the coastline through processes like corrasion, abrasion, hydraulic action, and attrition.

Human Activities

Human activities also contribute to coastal erosion. Coastal development, such as building seawalls and jetties, can disrupt natural sediment movement and increase erosion rates. Climate change, leading to sea level rise and more intense storms, further exacerbates coastal erosion.

Consequences of Coastal Erosion

Coastal erosion poses significant risks to communities, ecosystems, and infrastructure. It can result in the loss of property, damage to infrastructure, disruption of coastal ecosystems, and salinization of freshwater resources.
