Coastal erosion is a major concern in Senegal, which is increasing over time. In the Palmarin peninsula, in the Saloum estuary, previous studies showed shoreline retreat rates of 1.20 m/yr in 1982 and 2.20 m in 1954–2002; our results show an increase to 2.45 m/yr in 2005–2010, 2.60 m/yr in 2010–2014 and 3.05 m/yr in 2014–2018. The main cause seems to be sea level rise, as there are not significant human factors. Short-term estimates show probable damages in two villages (Ngallou and Djiffer), where buildings are already being destroyed, tourist camps near the beaches and on the road that crosses the peninsula. There is also a significant risk that coastal erosion would connect the sea and the intertidal mud flat areas of the Saloum estuary, fragmenting the peninsula in several islands, changing the evolution of erosive processes and producing a decline of the mangroves, and with them of fishing. It is urgent to develop an adaptation plan for this area, to address the possible consequences of coastal erosion on the assets and activities of the population.

Palmarin（塞内加尔）海岸侵蚀的演变

海岸侵蚀是塞内加尔的一个主要问题，随着时间的推移，这一问题正在增加。先前的研究表明，在Salalum河口的Palmarin半岛，海岸线退缩速度在1982年为1.20 m / yr，在1954–2002年为2.20 m。我们的结果显示，2005-2010年为每年245万，2010-2014年为260万/年，2014-2018年为305万。主要原因似乎是海平面上升，因为没有重大的人为因素。短期估计表明，在两个村庄（Ngallou和Djiffer），这些村庄的房屋已经被摧毁，海滩附近以及穿越半岛的道路上的旅游营地，​​可能造成了破坏。还有很大的风险，即海岸侵蚀将连接海洋和Saloum河口的潮间带滩涂区域，使几个岛屿的半岛破碎，改变侵蚀过程的演变并导致红树林的衰退，以及随之而来的捕鱼活动。迫切需要为此制定一项适应计划，以解决沿海侵蚀对人口资产和活动可能造成的后果。
