Because of this extremely low contrast desert landscape all color-spaces will EASILY render the scene (i.e. nothing will be clipped no matter what color-space is chosen). Inspecting the histograms reveals that editing resolution will be "clearly" maximum for an sRGB rendering (i.e. each sRGB channel histogram occupies a greater percentage of the 0,0,0 to 255,255,255 count range compared to either Adobe RGB or Pro Photo RGB). This is the sort of image that screams "use sRGB" for your rendering and editing color-space.
