The Value of the Mississippi Delta Ecosystem - Earth Economics
“As the great Mississippi River Delta disappears, so do the ecosystems, economies and people that it holds. The Mississippi River is the solution. It has the water, sediment and energy to rebuild land, defend against hurricanes and again provide habitat, safety, livelihood, and prosperity. We must loo
k to the natural functioning of the delta to guide us in restoration."
- John Day, 2007
The Mississippi River Delta ecosystems provide at least $12 – 47 billion in benefits to people every year. If this natural capital were treated like an economic asset, the present value of the Mississippi Delta would be between $330 billion and $1.3 trillion. T
hese are the findings of our report “Gaining Ground” just released by Earth Economics. To value the Delta, Earth Economics calculated the econ
omic value of
different land cover types, based on the ecosystem services that each
provides. Values have collected from the scientific literature,
currently housed in an Earth Economics database. See the full report
Valuing Ecosystem Services in Kamtchaka, Russia - The Wild Salmon Center
The Wild Salmon Center release of "The Value of the Kol River Salmon Refuge's Ecosystem Services" represents
the culmination of more than six months of work in partnership with the University of Vermont Gund Institute. This study
is the first attempt to approximate the total flow of ecosystem services in a healthy wild salmon ecosystem. This study
was conducted in the Kol salmon refuge, a whole basin Protected Area in Kamchatka, Russia created by partners with the
support of the Wild Salmon Center. The report asks the question: What is the economic value to society to preserve a
pristine salmon ecosystem like the Kol River Salmon Refuge?
The Kamchatka Peninsula, in the Russian Far East, is home to one
of the most productive salmon strongholds on earth
but it faces a number of threats from development of nonrenewable
resources (e.g. minerals, oil and gas). This development
path may provide short-term economic benefits, but may also
sacrifice the long-term economic productivity of a salmon ecosystem.
Ecosystem services, on the other hand, represent a collection of
renewable resources and processes that are supplied by natural
ecosystems and can provide long-term economic benefits to human
populations at local, regional and global scales. Benefits
include market and non-market services such as clean water,
biodiversity preservation, food production and recreation.
The Kol report and future studies will provide Wild Salmon Center
and its Russian partners with the initial information for
creating incentive-based mechanisms for salmon conservation such as
payments for ecosystem services. By understanding the link
between ecosystem services and human welfare, the range of benefits
that these watersheds provide can be communicated to
policymakers so they can make informed land management decisions.

Climate Change Impacts and Federal Lands Management - The Wilderness Society
The Intergovernmental Panel on Climate Change (IPCC) (2007) reports a likely 2°C to 4.5°C temperature rise in the upcoming decades. This warming is likely to affect ecosystems and their ability to provide services that benefit human well-being. Ecosystem services valuation (ESV), meanwhile, has emerged as a way to recognize the economic value embodied in these services that is not currently reflected in markets. To contribute to better understanding of, and therefore decision-making regarding, the costs and benefits of climate change, other measures affecting the management of the wilderness and other public lands where many ecosystem services are harbored or produced in abundance. We combine GIS analysis with the benefits transfer method to estimate potential global-warming-induced changes in the economic value of ecosystem services produced by US conservation lands.
Using conservative assumptions, the overall trend indicates that the majority of ecosystem services values decreases as temperature increases. While some ecosystem service values increase in the 2° scenario in several
regions, the values markedly decreased in all but one region under the 4.5° scenario. These results are consistent with other major studies such as the IPCC
and the Cost of Policy Inaction and indicate both the important role of public conservation lands in providing ecosystem services and the need for policy action to avoid major economic losses were climate change to impair the health of those lands. See full report.
