Project SummaryThe SAHEL project, sought to understand groundwater discharge and recharge since the LGM (Last Glacial Maximum) and the aeolian dune and lake changes since the Lateglacial in northeast Nigeria, an area highly sensitive to drought. Research at Kingston focussed on proxy (palaeolimnological) indicators of climate and vegetation change.
