Integrated land-sea planning in the Gulf of California, Mexico

Spatial management, including setting aside conservation areas, is central to curbing the global decline of biodiversity, but many threats originate from beyond the boundaries of conservation areas. This is a particular problem in marine systems, which are influenced by many activities on land. In particular, human-induced changes to river loads of nutrients and sediments pose a significant threat to coastal marine ecosystems. Ongoing land-use change can further increase these loads, and amplify the impacts of land-based threats on vulnerable marine species and habitats. Consequently, there is a need to assess these threats and prioritise actions to mitigate their impacts. Integrated land-sea conservation planning incorporates ecological connections between land and sea and seeks to limit land-based threats to coastal-marine ecosystems, while achieving conservation objectives on the land.

This dataset comprises four sub-datasets with spatial and non-spatial information required to develop and integrate models of catchments, land-use change, and river plumes with conservation planning software to inform prioritisation of catchment management in selected catchments draining into the Gulf of California, Mexico.

空间管理（包括划定保护区域）是遏制全球生物多样性衰退的核心举措，但诸多威胁源自保护区域边界之外。这一问题在海洋生态系统中尤为突出，因为海洋生态系统受到诸多陆地人类活动的影响。具体而言，人类活动导致的河流营养盐与沉积物输运量变化，对近岸海洋生态系统构成严重威胁。当前持续的土地利用变化会进一步加剧此类输运量，并放大陆地来源威胁对脆弱海洋物种与栖息地的影响。因此，亟需对这些威胁开展评估，并优先采取行动以减轻其造成的影响。
陆海统筹保护规划整合了陆地与海洋之间的生态联系，旨在限制陆地来源威胁对近岸海洋生态系统的影响，同时达成陆地保护目标。
本数据集包含四个子数据集，涵盖开发并整合流域（catchment）、土地利用变化与河流羽流（river plumes）模型所需的空间与非空间信息，用于与保护规划软件结合，为墨西哥加利福尼亚湾（Gulf of California）部分入海流域的流域管理优先级排序提供决策依据。
