Data from: A web platform for landuse, climate, demography, hydrology and beach erosion in the Black Sea catchment

The Black Sea catchment (BSC) is facing important demographic, climatic and landuse changes that may increase pollution, vulnerability and scarcity of water resources, as well as beach erosion through sea level rise. Limited access to reliable time-series monitoring data from environmental, statistical, and socio-economical sources is a major barrier to policy development and decision-making. To address these issues, a web-based platform was developed to enable discovery and access to key environmental information for the region. This platform covers: landuse, climate, and demographic scenarios; hydrology and related water vulnerability and scarcity; as well as beach erosion. Each data set has been obtained with state-of-the-art modelling tools from available monitoring data using appropriate validation methods. These analyses were conducted using global and regional data sets. The data sets are intended for national to regional assessments, for instance for prioritizing environmental protection projects and investments. Together they form a unique set of information, which lay out future plausible change scenarios for the BSC, both for scientific and policy purposes.黑海流域（Black Sea catchment, BSC）正面临显著的人口结构、气候与土地利用变化，此类变化可能加剧水污染、水资源脆弱性与短缺问题，同时因海平面上升引发海滩侵蚀。获取环境、统计及社会经济领域的可靠时序监测数据的渠道有限，这是阻碍政策制定与决策的主要瓶颈。为应对上述问题，研究团队开发了一款基于网页的平台，以支持该区域关键环境信息的检索与获取。该平台涵盖以下内容：土地利用、气候与人口情景；水文及相关水资源脆弱性与短缺状况；以及海滩侵蚀情况。所有数据集均依托现有监测数据，采用前沿建模工具与规范的验证方法生成。本次分析基于全球与区域数据集开展。本数据集可用于国家至区域尺度的评估工作，例如用于环保项目与投资的优先级排序。这些数据集共同构成了一套独特的信息体系，可为BSC梳理出未来合理的变化情景，适用于科学研究与政策制定两大场景。
