Land degradation in central Tanzania

这项研究探讨了坦桑尼亚中北部牧场的环境历史。它将最近的化石花粉数据与新的生态理论相结合，重新解释了对环境变化和近代人类历史的普遍理解。将利用花粉分析调查200年来的植被变化，并将这些结果与已知环境扰动的档案、书面和口头历史进行三角测量。我们将根据当前的生态思想开发感知环境退化的替代解释，并将自然科学的方法和理论整合到环境历史中。

This research explores environmental histories in the rangelands of north central Tanzania. It integrates recent fossil pollen data with new ecological theories to re-interpret prevailing understandings of environmental change and recent human history. Vegetation changes over 200 years will be investigated using pollen analysis and these results will be triangulated with archival and written and oral histories of known environmental perturbations. We will develop alternative explanations of perceived environmental degradation based on current ecological thinking, and will integrate methods and theories from the natural sciences in to environmental history.
