Africa Carbon Biomass

Retirement Notice: This item is in mature support as of October 2025 and will be retired in December 2026. There are a number of layers available in ArcGIS Living Atlas of the World which could be used as a replacement. Esri recommends updating your maps and apps to use the new version. Plants play a central role in the carbon cycle by absorbing carbon dioxide from the atmosphere and incorporating it in the structure of the plant. Globally living plants contain 500 billion metric tons of carbon, more than 60 times the amount of carbon released to the atmosphere by humans each year. Understanding the distribution of the carbon stored in living plants, known as biomass, is key to estimating the effects of land use change on the climate. Dataset Summary This layer provides access to a 1 km cell sized raster with data on the density of carbon stored in living plants in metric tons per hectare for the year 2000. The data covers Africa, Madagascar, and other islands near Africa. It was published by the Oak Ridge National Laboratory Carbon Dioxide Information Analysis Center in 2008.停用通知：本数据集自2025年10月起进入成熟支持阶段，并将于2026年12月正式停用。您可使用ArcGIS世界生活地图集（ArcGIS Living Atlas of the World）中的多个图层作为替代方案，Esri建议您更新相关地图与应用程序以使用新版本图层。 植物通过吸收大气中的二氧化碳并将其整合进自身组织结构，在碳循环中发挥核心作用。全球现存植物的碳储量达5000亿吨，是人类每年向大气排放碳量的60倍以上。明确现存植物体内储存的碳（即生物量）的分布情况，是评估土地利用变化对气候影响的关键所在。 数据集摘要：本图层提供分辨率为1公里栅格单元的栅格数据，展示了2000年非洲、马达加斯加及非洲周边群岛区域内，现存植物的碳储量密度（单位：吨/公顷）。该数据集由橡树岭国家实验室二氧化碳信息分析中心（Oak Ridge National Laboratory Carbon Dioxide Information Analysis Center）于2008年发布。
