NEA Economic methodology
• Avoid ‘Total Value of Ecosystem Services’ approach:
o Of no policy use
o Wrong (total value of ecosystem = infinity)o The approach takes the value of a single unit
(the ‘marginal value’) of ecosystem service and multiplies by the total number of units
o But as the number of units decreases so their marginal value increases
![Page 9: An Economic Assessment of UK Ecosystem Services Bateman's Presentation... · UK Ecosystem Services ... Abbey Conference Centre, Carrow, Norwich NR1 2DD. Wednesday, 6 October 2010.](https://reader031.fdocuments.in/reader031/viewer/2022022520/5b1ef0b17f8b9a22028c2cb7/html5/thumbnails/9.jpg)
NEA Economic methodology
• Estimate marginal values• Apply to valuing the changes in service levels
generated by feasible policies or scenarios. • For example: o Likely climate change and its impactso Planting new woodlandso Changes in agricultural land use o NEA Scenarioso etc

NEA Final Phase (to end of 2010)
• Review and revise• Complete the analysis
o Address commonalities and overlapso Focus broadens from habitats to goodso Marginal values
o Per hectare valueso Value functions
• Feed into NEA Scenario analysis
![Page 15: An Economic Assessment of UK Ecosystem Services Bateman's Presentation... · UK Ecosystem Services ... Abbey Conference Centre, Carrow, Norwich NR1 2DD.

Economic methodology: Limitations
• If feasible changes are substantial enough then the marginal values will begin to alter
• This links the value of service ‘flows’
to the size of the ‘stock’
of ecosystem assets they are
provided by: o E.g. the value of each tonne of fish landed will
rise as the stock of fish falls. • Need to adjust marginal values for this (tricky –
but attempting with a fisheries case study)• Alternative: Asset check (Defra project)
![Page 16: An Economic Assessment of UK Ecosystem Services Bateman's Presentation... · UK Ecosystem Services ... Abbey Conference Centre, Carrow, Norwich NR1 2DD. Wednesday, 6 October 2010.](https://reader031.fdocuments.in/reader031/viewer/2022022520/5b1ef0b17f8b9a22028c2cb7/html5/thumbnails/16.jpg)
Economic methodology: Limitations
• While most ecosystem services can be valued in economic terms, some are problematic
• While in principle we can estimate the use
value of biodiversity
(e.g.
pollination
services,
bird‐
watching,
etc.),
the
non‐use
existence
value
of conservation is more difficult to assess.
o E.g. Non‐birdwatchers value for preserving bird species which don’t contribute to provisioning
• Here I argue for an ecological limits approach with economics confined to identifying cost‐effective
methods of ensuring safe minimum standards (which may be above present levels).

Decision making problem:
While
in
principle
we
can
estimate
the
use
value
of biodiversity
(e.g.
pollination
services,
bird‐watching,
etc.),
the
non‐use
existence
value
of
conservation
is
more difficult to assess.
• Can
we
use
economic
analysis
to
target
where
is
it
most cost‐effective to undertake conservation?
• Can conservation costs be compensated for?

Conclusions
• Efficient use of resources is always necessary, but especially so in times of austerity
• Integrated environmental economic analysis can target policy so as to optimise efficiency and make the most
of scarce resources. • Advances in valuation mean that, in many cases, CBA
of environmental policy is feasible. • Even where this is not the case, CEA can help target
policy
