What is one of the dangers of replacing eroded beach sand with dredged sand from offshore12/17/2023 ![]() Understanding and advocating for their ecological value has been a key part of beach management and destination strategies to ensure that coastlines and their ecosystems continue to thrive. Preserving these Posidonia oceanica banquettes has been crucial to preventing the losses of coastlines, which plagues many beaches, especially those located on the Mediterranean. This was demonstrated by a 2006 study where researchers removed Posidonia oceanica seagrass banquettes from an island, which resulted in sediment loss from the beaches. The combination of plant life and the wildlife that inhabit these areas, anchor the sand in place. One of the most environmentally safe ways of staving off coastal erosion is adding vegetation to the beach. Some of the most popular soft solutions include: They are widely considered more environmentally friendly than hard solutions, but they also tend to be less effective at preventing coastal erosion long-term. Soft solutions don’t require creating synthetic structures in the beach’s ecosystem. There are a couple of solutions to help keep our beaches from being swallowed up by the ocean: According to a 2020 study, half of the beaches worldwide will disappear by the end of the century. This problem has been hastened by climate change, prompting stronger and more frequent storms that cause more sand to retreat into the ocean. A problem that has plagued most coastal regions is the fast rate of erosion. ![]() However, just like any other natural area, beaches are subject to change. This is no surprise since the beach is a great place to have fun, relax and enjoy the scenery. According to the National Oceanic and Atmospheric Administration, around 40% of Americans live in coastal areas.
