Presentation to the Project Inception Workshop
4 December, 2012
Purpose of the Presentation
The purpose of this presentation is outline the
programme’s :
• Aims
• Rationale and Philosophy
• Key methodological steps
Please ask questions and have a discussion.
Nothing is ‘set concrete’ at this stage !!!!
Programme Aim and Scope (Yrs 1-2)
• Our aim is to develop a robust framework to characterise,
biophysically quantify, map and value coastal-marine
ecosystem services.
• The intention of the research is to ‘make visible’ coastalmarine ecosystem services that are often ignored in
resource management and business decision-making.
•
We will use Tasman Bay as a test-bed for our research in
years 1 & 2, with further research signalled in the full
proposal.
Programme Aim and Scope (Yrs 3-4)
•
At this stage, there is no guarantee that will fund of years
three and four
• However, our proposal indicated that Years 3-4 would:
 Extend the valuation/quantification method to cover
all of New Zealand’s coasts and oceans
 More fully develop the valuation/quantification
method to find solutions to resource management
problems – ‘exemplar’ case studies
 Apply valuation/quantification method to a national
scale marine policy issue.
Programme Steps
STEP 1 Conceptualisation of Ecosystem Services in
Tasman Bay
• No one unequivocal conceptual framework service
• Much debate over terminology and methodological issues
such as double counting
• Most classification systems have been developed for
terrestrial ecosystems
• Social and cultural dimensions are important
Step 1 will be particularly important in the first few months,
but will continue the lifespan of the programme
STEP 2: Biophysical Quantification and Mapping
Step 1:
Ecosystem Services
Conceptual Framework
Step 2a:
Ecological
Understanding
of Tasman Bay
Step 2b:
Ecosystem Services
Indicators for
Tasman Bay, defined
in biophysical terms
(Ideal)
Step 2c:
GIS Data Layers
for Tasman Bay
•Substrate Layers
•Seabed benthic
communities and habitats
•Water Column hydrology
•Water column biology
•Human Activities
Step 2d:
Reality Check IF
no GIS data, then
can’t quantify and
map
Step 2e: Maps of
ecosystem Services
indicators for
Tasman Bay, defined
in biophysical terms
(Approx 15-20 maps)
Investigate ways
of generating
missing GIS
layers.
Limited funding to
do this in Years 3
and 4.
Step3:
Economic
Valuation
Programme Steps
STEP 3
Is there times series data available?
If so we could generate ‘radar diagram’ like this, which is good for non-commensurable
physical units:
Programme Steps
STEP 3 Economic Valuation of Coastal Marine
Ecosystem Services

Biophysical indicators  converted to economic values  maps economic
values of ecosystems

Main economic valuation methods to be used will be:






Other non-monetary metrics will be used as appropriate




Avoided cost
Replacement cost
Hedonic pricing
Contingent valuation
Benefit transfer
Cultural Values
Intrinsic Value
Contributory Value
One critical/reflective article on limitations of these valuation methods, will be
produced
Programme Steps
STEP 4: Matauranga Maori interpretation of ecosystem
services
Research questions include:
 How relevant is ecosystem services concept from an Matauranga Maori perspective?
 All too often cultural values as seen just as ‘another category’ ecosystem services – a
box to be ticked off. Is this appropriate or are the better ways of approaching the
problem.
 Can an we diviise alternative framework to ‘ecosystem services’ for hapu/iwi?
One report will be produced to summarise these issues, and provide guidance hapu/iwi.

Programme Steps
STEP 5:
Application to a Practical Problem in Nelson
Bays

‘Short-sharp’ application – only two or three months

Years 3-4 will focus more on applying the method to practical problems.

Any suggestions ?
Study Boundaries?
• Tasman Bay and Golden Bay? Or just Tasman Bay?
(By including Golden Bay to do capture any extra
ecosystem services or processes?
• How far out to sea?
Tasman Bay and Golden Bay?
Documentation
• Detailed Methodology (7 pages)
• Full Proposal – minus CVs (32 pages)
Everyone should have a copy of these

• Joanne Paul Gillespie or Chris Cornelisen to provide this
overview.
•
Rationale for the ecosystem
services approach
• Makes ecological processes/functions visible
• Can compare ecological values and economic values in
same terms
• We intend to shift thinking about coastal-marine
management away from a fragmented concentration on
single issues, single processes and single resources, to a
more holistic appreciation of the whole-of-system
ecosystem services values and processes
