Coastal catchment zones have undergone enormous changes during recent decades that have compromised their resilience. As a consequence of largely fragmented coastal management frameworks in the delta region of the Tordera River, the beach of S’Abanell, located on the northern arm of the delta, was in a critically degraded condition by the end of 2006. To remedy this situation, the beach was artificially nourished with sand during the period 2007–2009. After nourishment, we observed a general trend of recovery of the width of the beach, in its northern and central parts, and the reappearance of a pattern of seasonal oscillation. This tendency was not observed in its southern part, near the river mouth, where the situation is still critical today. Tracing the decadal evolution of the problem, we strengthen the knowledge base by compiling a history of past human decisions responsible for the present situation. We promoted stakeholder engagement and participation aimed at reducing human pressures affecting the evolution of the beach and the loss of ecosystem services. The overall idea was to take the initial steps needed to shift the management of this coastal region towards ecosystem-based management principles. This research demonstrates that, under certain conditions, artificial nourishment can contribute to restoring beach health on a decadal scale.

评估西班牙东北部Tordera三角洲的海岸线综合管理的成功

近几十年来，沿海集水区发生了巨大变化，损害了其韧性。由于Tordera河三角洲地区的沿海管理框架大为零散，位于三角洲北端的S'Abanell海滩到2006年底处于严重退化的状况。为纠正这种情况，该海滩在2007年至2009年期间被人工添加了沙子。营养后，我们观察到海滩北部和中部的宽度恢复了总体趋势，并且出现了季节性振荡模式。在南部靠近河口的地方没有观察到这种趋势，那里今天的局势仍然很严峻。追踪问题的年代演变，我们通过汇编对当前情况负责的过去人类决策的历史来增强知识库。我们促进了利益相关者的参与和参与，旨在减轻影响海滩演变和生态系统服务丧失的人类压力。总体思路是采取必要的初始步骤，将沿海地区的管理转向基于生态系统的管理原则。这项研究表明，在一定条件下，人工营养可以在十年的规模上有助于恢复海滩健康。总体思路是采取必要的初始步骤，将沿海地区的管理转向基于生态系统的管理原则。这项研究表明，在一定条件下，人工营养可以在十年的规模上有助于恢复海滩健康。总体思路是采取必要的初始步骤，将沿海地区的管理转向基于生态系统的管理原则。这项研究表明，在一定条件下，人工营养可以在十年的规模上有助于恢复海滩健康。
