Key Note Presentation by Prof. Alan MacDonald @ 1st SADC Groundwater Conference
Keywords: (Drought, Climate, Change, Infrastructure, Groundwater Resources, Resilience).
“Recent droughts have highlighted the need to understand and forecast the resilience of water supplies to climate variability. Resilience of groundwater supplies is determined by several factors: groundwater storage; long term recharge; permeability; and the infrastructure put in place to abstract groundwater.
“Drawing on recent research from across Africa, mainly funded through the UPGro programme, this talk examines the relative importance of each of these factors for rural drinking water supplies, and attempts to distinguish between the behaviour of the groundwater resource and the water infrastructure.
“A variety of data are presented and evaluated: detailed groundwater level monitoring of springs, wells and boreholes; national survey data of borehole functionality; groundwater residence time indicators; and also information from GRACE and global Land Surface Model.”
