Time of emergence of impacts of climate change on groundwater levels in sub-Saharan Africa Open
The impacts of climate change on groundwater are poorly constrained, particularly in regions such as sub-Saharan Africa where global circulation models (GCMs) project different directions of precipitation change. Moreover, the timing of wh…
