Millennium Ecosystem Assessment: MA Scenarios

The Millennium Ecosystem Assessment: MA Scenarios provides data and information on population, income, cereal production and consumption, meat production and consumption, land cover, water stress, water availability, acidification and nitrogen deposition. These scenarios provide useful insight into the complex factors that drive ecosystem change, estimating the magnitude of regional pressures on ecosystems and critical uncertainties that could undermine sustainable development. They also provide an understanding of the importance of institutions and values as the long-range outlook for the world's ecosystems depends on the course taken by global and regional development in the coming decades. The integration of changing ecosystem conditions into the global scenarios was taken as both effects and causes.

千禧年生态系统评估：MA情景数据集提供了关于人口、收入、谷物生产与消费、肉类生产与消费、土地覆盖、水资源压力、水资源可用性、酸化和氮沉降等方面的数据和信息。这些情景分析有助于深入理解驱动生态系统变化的复杂因素，评估区域对生态系统造成的压力及其可能破坏可持续发展的关键不确定性。此外，该数据集还揭示了制度与价值观的重要性，因为世界生态系统长期展望取决于未来几十年全球及区域发展轨迹。将不断变化的生态系统条件融入全球情景分析时，既将其视为影响，亦将其视为原因。
