Effect of land use change on the overall provision of regulating ES given different parameters specification.Source: author’s own elaboration. Notice that equation 5 is defined in terms of C and H, however, H is a function of C. Thus, the resulting curve can be plotted using only in terms of C. Parameter specification is as follows: Black curve: s = 0.7, α = 0.5Blue curve: s = 0.4, α = 0.7Red curve: s = 0.5, α = 0.7Gray curve: s = 0.25, α = 0.75
