This study provides an overview of 11 lagoons in North Africa, from the Atlantic to the Eastern Mediterranean. Lagoons are complex, transitional, coastal zones providing valuable ecosystem services that contribute to the welfare of the human population. The main economic sectors in the lagoons included fishing, shellfish harvesting, and salt and sand extraction, as well as maritime transport. Economic sectors in the areas around the lagoons and in the watershed included agriculture, tourism, recreation, industrial, and urban development. Changes were also identified in land use from reclamation, changes in hydrology, changes in sedimentology from damming, inlet modifications, and coastal engineering. The human activities in and around the lagoons exert multiple pressures on these ecosystems and result in changes in the environment, affecting salinity, dissolved oxygen, and erosion; changes in the ecology, such as loss of biodiversity; and changes in the delivery of valuable ecosystem services. Loss of ecosystem services such as coastal protection and seafood affect human populations that live around the lagoons and depend on them for their livelihood. Adaptive management frameworks for social–ecological systems provide options that support decision makers with science-based knowledge to deliver sustainable development for ecosystems. The framework used to support the decision makers for environmental management of these 11 lagoons is Drivers–Activities–Pressures–State Change–Impact (on Welfare)–Responses (as Measures).

北非沿海泻湖管理的社会环境分析

本研究概述了北非从大西洋到东地中海的 11 个泻湖。泻湖是复杂的、过渡性的沿海地区,提供有助于人类福祉的宝贵生态系统服务。泻湖的主要经济部门包括捕鱼、贝类捕捞、盐和沙提取以及海上运输。泻湖周围地区和流域的经济部门包括农业、旅游、娱乐、工业和城市发展。还确定了开垦土地利用、水文变化、筑坝造成的沉积学变化、入口改造和海岸工程的变化。泻湖内和周围的人类活动对这些生态系统施加多重压力,导致环境发生变化,影响盐度、溶解氧和侵蚀;生态变化,例如生物多样性的丧失;以及提供有价值的生态系统服务的变化。沿海保护和海鲜等生态系统服务的丧失影响了生活在泻湖周围并依赖他们谋生的人口。社会-生态系统的适应性管理框架提供了支持决策者以科学知识为生态系统实现可持续发展的选择。用于支持决策者对这 11 个泻湖进行环境管理的框架是驱动因素 - 活动 - 压力 - 状态变化 - 影响(对福利) - 响应(作为措施)。沿海保护和海鲜等生态系统服务的丧失影响了生活在泻湖周围并依赖他们谋生的人口。社会-生态系统的适应性管理框架提供了支持决策者以科学知识为生态系统实现可持续发展的选择。用于支持决策者对这 11 个泻湖进行环境管理的框架是驱动因素 - 活动 - 压力 - 状态变化 - 影响(对福利) - 响应(作为措施)。沿海保护和海鲜等生态系统服务的丧失影响了生活在泻湖周围并依赖他们谋生的人口。社会-生态系统的适应性管理框架提供了支持决策者以科学知识实现生态系统可持续发展的选择。用于支持决策者对这 11 个泻湖进行环境管理的框架是驱动因素 - 活动 - 压力 - 状态变化 - 影响(对福利) - 响应(作为措施)。社会-生态系统的适应性管理框架提供了支持决策者以科学知识为生态系统实现可持续发展的选择。用于支持决策者对这 11 个泻湖进行环境管理的框架是驱动因素 - 活动 - 压力 - 状态变化 - 影响(对福利) - 响应(作为措施)。社会-生态系统的适应性管理框架提供了支持决策者以科学知识为生态系统实现可持续发展的选择。用于支持决策者对这 11 个泻湖进行环境管理的框架是驱动因素 - 活动 - 压力 - 状态变化 - 影响(对福利) - 响应(作为措施)。
