Soil Erosion Dynamics in an Urbanised Greater Accra Metropolitan Area

This study used qualitative and quantitative datasets to assess erosion rates across the landscape within the Greater Accra Metropolitan Area (GAMA) of Ghana. The quantitative dataset included the Gerlach assessment and physicochemical measurements of soil and RUSLE mapping. The qualitative data were household interview data obtained from the CLIMACCESS project in Ghana.本研究采用定性与定量两类数据集，对加纳大阿克拉都会区（Greater Accra Metropolitan Area, GAMA）全域景观的土壤侵蚀速率开展评估。定量数据集涵盖格奇侵蚀测定法（Gerlach assessment）相关数据、土壤理化性质检测结果，以及修订版通用土壤流失方程（RUSLE）制图数据；定性数据则来源于加纳CLIMACCESS项目的家庭访谈资料。
