Millennium Ecosystem Assessment: MA Biodiversity

The Millennium Ecosystem Assessment: MA Biodiversity provides data and information on amphibians, disease agents (extent and distribution of infectious and parasitic diseases), drylands (cattle, sheep and goats, and pasture), islands (fishing pressure, sewage pollution index and tourism), loss of natural land cover (biomes and realms), polar population, species distribution models, and terrestrial ecoregions and realms. Biodiversity is defined as the variability among living organisms from all sources, including terrestrial, marine, and other aquatic ecosystems and the ecological complexes of which they are a part. The original information was received from multiple sources that include the International Union for Conservation of Nature (IUCN, formerly the World Conservation Union), the World Wildlife Fund (WWF), the History Database of the Global Environment (HYDE) of Netherlands Environmental Assessment Agency (PBL), and the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument on-board NASA satellites Terra and Aqua. Through the Convention on Biological Diversity, United Nations Convention to Combat Desertification, Ramsar Convention on Wetlands, and the Convention on Migratory Species, the data were also designed to meet the needs of stakeholders in the business, civil and native communities.
To preserve access to the original biodiversity data used by the Millennium Ecosystem Assessment (MA) and other related research.

《千年生态系统评估（Millennium Ecosystem Assessment, MA）生物多样性数据集》涵盖以下类别的数据与信息：两栖动物、病原体（传染病与寄生虫病的波及范围及分布）、干旱地区（牛、绵羊、山羊种群及牧场资源）、岛屿区域（捕捞压力、污水污染指数与旅游相关数据）、自然土地覆被丧失（生物群区与生物域）、极地种群、物种分布模型以及陆地生态区与生物域。
本数据集所界定的生物多样性，指源自陆地、海洋及其他水生生态系统，及其所属生态复合体的所有活生物体之间的变异性。
本数据集的原始信息来源于多个机构，包括国际自然保护联盟（International Union for Conservation of Nature, IUCN，前身为世界保护联盟）、世界自然基金会（World Wildlife Fund, WWF）、荷兰环境评估署（Netherlands Environmental Assessment Agency, PBL）的全球环境历史数据库（History Database of the Global Environment, HYDE），以及搭载于美国国家航空航天局（National Aeronautics and Space Administration, NASA）Terra与Aqua卫星的中分辨率成像光谱仪（Moderate Resolution Imaging Spectroradiometer, MODIS）。
依托《生物多样性公约》《联合国防治荒漠化公约》《拉姆萨尔湿地公约》及《保护迁徙物种公约》，本数据集的设计初衷还包括满足商业、公民及原住民社区利益相关方的相关需求。
本数据集旨在留存《千年生态系统评估（MA）》及其他相关研究中所使用的原始生物多样性数据，保障其可获取性。
