Changes in Ugandan Climate Rainfall at the Village and Forest Level
摘要：
2013年，美国国家海洋和大气局改进了非洲大陆的历史降雨量估计，并制作了非洲降雨气候2.0版（ARC 2）估计器。ARC 2提供了自1983年以来几乎完整的每日降雨量估计记录，分辨率为0.1 x 0.1度。尽管短期异常，在每年两次的雨季强度在乌干达，我们确定在过去的34年中，平均降雨量约12%的整体下降。从时空上看，乌干达中部和西部农业地区的降水量减少最多，但也反映了乌干达西南部布温迪森林大猩猩栖息地的降雨量减少。这些发现对农业、粮食安全和野生动物栖息地具有重要意义。
英文摘要：
In 2013, the US National Oceanographic and Atmospheric Agency refined the historical rainfall estimates over the African Continent and produced the African Rainfall Climate version 2.0 (ARC2) estimator. ARC2 offers a nearly complete record of daily rainfall estimates since 1983 at 0.1 x 0.1 degree resolution. Despite short-term anomalies in twice-yearly rainy season intensities in Uganda, we identify an overall decrease in average rainfall of about 12% during the past 34 years. Spatiotemporally, these decreases are greatest in agricultural regions of central and western Uganda, but are also reflective of rainfall decreases in the gorilla habitat within the Bwindi Forest in Southwest Uganda. The findings carry significant implications for agriculture, food security, and wildlife habitat.
