4.4 Publication distribution on a funding basis
The authors of 19 of the articles reported funding sources. Table 3 shows the funding sources of the studies recovered in our studies. We observe that only two articles report a funding source from Ghana, where the Bosumtwi Impact Crater is located. These studies are Aning et al. (2013 ) and Habimana et al. (2020 ). Habimana et al. (2020 ) also reported support from the University of Rwanda. The predominant source of funding for the studies is from external funding agencies in countries such as Austria, Germany, Canada and USA.
