- ... Inappropriate agricultural practices and conversion of marginal land to cultivation and grazing have led to severe land degradation in the Ethiopian highlands. Consequently, the government has invested substantial resources in soil and water conservation (SWC). One of such interventions was exclosure, which was aimed restoring biodiversity, biomass and soil fertility. The aim of this study was to ...

- ... Soil organic carbon (SOC) in high latitude ecosystems is potentially vulnerable to global climate change. However, the distribution of SOC and total nitrogen (N) is still unknown for the boreal wetlands. In this study, we collected soil samples from different wetlands in the discontinuous permafrost zone of the Xiao Xing'an Mountains, northeastern China. Permafrost was only present in the bogs and ...
