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.

千年生态系统评估：MA生物多样性数据集提供了关于两栖动物、疾病传播者（传染性和寄生虫病的范围与分布）、干旱地区（牛、羊和山羊以及牧场）、岛屿（捕鱼压力、污水污染指数和旅游业）、自然土地覆盖丧失（生物群系和生态域）、极地人口、物种分布模型以及陆地生态区域和生态域的数据和信息。生物多样性被定义为所有来源的活生物体之间的可变性，包括陆地、海洋以及其他水生生态系统及其所属的生态复合体。原始信息来源于多个渠道，包括国际自然保护联盟（IUCN，前称世界自然保护联盟）、世界野生动物基金会（WWF）、荷兰环境评估局（PBL）的全球环境历史数据库（HYDE）以及NASA卫星Terra和Aqua上的中分辨率成像光谱辐射计（MODIS）。通过生物多样性公约、联合国防治荒漠化公约、拉姆萨尔湿地公约和迁徙物种公约，这些数据还旨在满足商业、民事和土著社区利益相关者的需求。
