ABSTRACT
The natural capital concept attempts to integrate economic thinking with ecological principles by considering nature’s stocks of materials and energy as capital. In economics, interest, or rents, ow from nancial or built capital, and so by analogy in nature, ecosystem services, which benet mankind, ow from natural capital stocks. Nature comprises an assemblage of natural capital stocks, and they, in sum, form our ecological infrastructure. Marchant et al. (2013) consider ecological infrastructure to be how natural capital is arranged. Bristow et al. (2010) noted that soil is a key component of ecological infrastructure, and that it is a prime natural capital stock that provides valuable ecosystem services.
