LBA-ECO LC-14 Modeled Deforestation Scenarios, Amazon Basin: 2002-2050

This data set provides the results of the two modeled scenarios for future patterns of deforestation across the Amazon Basin from 2002 to 2050. This larger defined Amazon Basin (PanAmazon area) includes the Amazon River watershed, the Legal Amazon in Brazil, and the Guiana region.

The model SimAmazonia was used to simulate monthly deforestation in the Amazon Basin from 2002 to 2050 for two scenarios: (1) a "Business-as-Usual" scenario, which considered the deforestation trends across the basin and projected the rates by using historical images and their variations from 1997 to 2002 and then added to that the effect of paving a set of major roads, and (2) a "Governance" scenario, that also considered the current deforestation trends, but assumed a 50% limit imposed for deforested land within each basin's subregion, and that existing and proposed Protected Areas (PAs), play a decisive role in limiting deforestation as well (Soares et al., 2006).

The provided data products include one GeoTiff (*.tif) for each year (2002 to 2050) for both model scenarios for a total of 98 files. The files have been compressed in two *.zip files, one for each model scenario. There is also one comma-delimited file that contains the model input data derived from satellite deforestation maps.

本数据集提供了对亚马逊盆地2002年至2050年间未来森林砍伐模式进行模拟的两个情景的结果。该定义更为广泛的亚马逊盆地（泛亚马逊地区）包括亚马逊河流域、巴西的亚马逊地区以及圭亚那地区。

模型SimAmazonia被用于模拟2002年至2050年间亚马逊盆地每月的森林砍伐情况，针对两种情景：一是“现状持续”情景，该情景考虑了整个盆地的森林砍伐趋势，并利用1997年至2002年的历史影像及其变化率进行预测，随后在此基础上增加了主要道路铺设的影响；二是“治理”情景，该情景同样考虑了当前的森林砍伐趋势，但假设每个子区域内的森林砍伐土地限制在50%以内，并且现有及拟议中的保护区（PAs）在限制森林砍伐中发挥着决定性作用（Soares et al., 2006）。

提供的数据产品包括每个年份（2002年至2050年）针对两种模型情景的GeoTiff (*.tif) 文件各一个，总计98个文件。这些文件已分别压缩成两个*.zip文件，分别对应两种模型情景。此外，还包括一个以逗号分隔的文件，其中包含从卫星森林砍伐地图中提取的模型输入数据。
