Fig. 1From: Geographical heterogeneity and inequality of access to improved drinking water supply and sanitation in NepalSamples of nationally representative cluster survey on improved WSS and the predicted population coverage in Nepal 2011. (a) and (b) represent the access to improved sanitation and improved drinking-water supply, respectively, with the same location but different coverage. Predicted improved sanitation at 1 KM2 resolution is shown in (c) and improved drinking water in (d).(The number in the legend is the value of coverage)Back to article page
