Beach erosion is a big problem at Bamburi beach in Kenya, causing damage to expensive developments and threatening the local community. By measuring changes in beach width, researchers found that different parts of the beach are eroding at different rates. They used this information to create a map showing areas most at risk of erosion. The study suggests that managing beach erosion should take into account the specific characteristics of each beach area. Areas with shrinking beaches need strategies to keep sand in place, while areas with growing beaches can share sand with eroding areas. This approach could help protect the shoreline and the community that depends on it.
