Nature's services is an umbrella term for the ways in which nature
benefits humans, particularly those benefits that can be measured in economic terms. Robert Costanza and other theorists
of natural capital conducted extensive economic analysis of nature's services to humanity in the
1990s. The economic contribution of seventeen of these was found to be approximately
US$33 trillion per year, greater than the activities in the inter-human economy, which totaled about US$25 trillion. This was
based on estimated costs of replacing the services nature provides, with equivalent services using methods wholly based on human
infrastructure.
This study has been widely cited in natural capital, value of Earth and value of
life debates. It is a cornerstone of human
development theory and Natural Capitalism. It has also had
broad influence on theories of service economy, which redefine
commodity markets and brand name product sales strictly as services: for example, governments
providing means of protection of the natural capital which
automatically provides such services as:
- erosion
prevention
- water filtering
- pest control
Worldwatch Institute, World Resource
Institute, Rocky Mountain Institute, Greenpeace, and various United
Nations agencies, along with a few governments (including the United
Kingdom and Canada) are actively expanding the analysis, with an eye to producing
UN standards for valuating natural capital. This is anticipated to
have a major effect on money supply debates, as the creation of money by
banks for purposes of funding ecosystem depletion has become a major global governance issue, of importance equivalent to land reform, developing nation debt and terrorism. In combination, these are thought by some theorists, including Thomas Homer-Dixon, to be
closely related to ecological depletion and heightened competition for scarce natural resources. If the nature's services analysis is valid, then humans also compete to protect the
natural capital which in turn provides them services they cannot pay
for in a cash economy. Funding its depletion thus creates a vicious
cycle.
However, this debate appears to have had little influence on monetary
policy or on WTO, IMF or G8 economic and trade policy. The anti-globalization movement, ecology movement, peace movement, and conservation movement, and their political ally the Green movement are increasingly vocal about the need to reflect the value of
these services directly in real policy. Such an approach would, for example, mean not funding such projects as the Three Gorges Dam which directly deplete and disrupt ecoregions on a huge scale. This debate precedes economic analysis of the services,
which was in part motivated by the observation that human instinct and economic analysis very often yielded quite different
impressions of the value of such ecosystems.
One criticism of this analysis is that it is largely conducted by those who have some association with Gaia philosophy and human development theory and one or more political movements seen to have an ideological bias in favor of a higher valuation for
nature's services than would be implied by a more neutral
point of view. Accordingly, many of the debates now focus on metrics and indicators on which both advocates and detractors of
monetary reform can agree. These are in general indistinguishable
from debates about measuring well-being to determine what
constitutes real inflation, that is, the amount of money required to live the
same way, and other debates regarding the social welfare
function and what constitutes wealth.
