Dear Andy, Subhashni and others interested,
Some points regarding the full costs and benefits of protecting marine
Protecting areas for conservation results in 3 main categories of costs
1) Direct costs - economic/financial costs of establishment and ongoing
2) Indirect costs - covering environmental, social and economic impacts:
a) Environmental impacts can include erosion, trampling, waste,
disturbance of animals, feeding animals thus upsetting foodwebs etc if
visitor activities are inadequately managed. If management enables some
species to multiply unchecked, this can also affect associated species
b) Social impacts can include social conflicts arising from pro/anti
protected area groups of people (often job/income related), and if
tourism is significantly enhanced, various adverse tourism-related social
issues can arise. In addition, various social issues are likely
to arise due to opportunity costs forgone - see below).
c) Economic impacts can include things such as potentially
increasing property prices in nearby areas and loss of economic produce
(e.g. crops, yields of fish) due to increased populations of some species.
3) Opportunity costs - economic costs associated with being unable to
undertake other economic activities in (and sometimes near) the protected
area. This can lead to loss of economic output (e.g. from fishery yields,
tourism development), traditional jobs and nutritional sources etc.
Benefits converted into monetary values can be extremely powerful - if used
and expressed appropriately. However, despite the hugely significant value
of coral reefs, disappointingly little is really known about their true
economic value! Although a few studies have demonstrated high values
associated with some benefits (e.g. fishing income/tourism
expenditure/erosion protection etc) there is a dearth of them, they are
rarely fully comprehensive, and the supporting assumptions are usually
rather weak. As ever, much of this situation is to do with funding
constraints rather than anything else.
Data on ecological:socio-economic links is generally fairly poor (e.g.
dependance of fisheries on corals and cause-effect relationships of human
impacts), as is our understanding of most of the benefits. In particular,
little is known about non-use (passive) values, which for some coral reefs
(e.g. North West Hawain Islands) will be immense! This situation really
should change if we want more appropriate levels of funding allocated to
protecting and studying reefs. Here in the UK, non-use values are now
beginning to be accounted for in complex resource related decision-making
processes, with more research being undertaken to better understand them.
Anyone who wants more information on these types of issues should read the
excellent (but a little dated) book by Dixon and Sherman (1990) Economics of
protected areas: a new look at benefits and costs. Island Press, Covelo,
Some issues (e.g. non-use values) are discussed further in Spurgeon (2001)
Valuing Coral Reefs: The next ten years. Downloadable from Reefbase, or I
can email you a copy.
In addition, we at Jacobs are currently undertaking a detailed
multi-questionnaire survey based investigation into the full costs and
benefits (including expenditures/non-use values etc) of designating 300
protected areas in Scotland. The aim is to help the Scottish Executive
identify winners and losers; determine priorities for expenditure; seek ways
to enhance benefits; and help identify revenue generating opportunities.
Our preliminary report will be available online in a month or two, and the
final report hopefully early next year. Although corals are not mentioned
too often, the principles are nevertheless highly relevant!

Subject: Re: [Coral-List] Coral reefs importance brainstorm
Thank you Andrew for bringing up this point, and to all the others who
have provided excellent resources on the economic value of healthy
reefs, and other information. I do certainly agree that management
decisions based solely on the factor of economic value are ridiculuos
and will most certainly lead to resource depletion and destruction
through one path or another. Lets face it, there are fisherpeople out
there who fish sustainably, and there are eco-tourist divers who cause
destruction with their fins. It is the cumulative impact of all forms
of use and extraction, non-point source impacts such as marine debris
and global temperature change, and a whole host of site specific
degrading factors that are causing, or have caused the demise of coral
In order to connect an individual's behavior to the damage being done
the critical connections need to be made, and in order to do this people
need to see how they are connected to the reef. I wanted info on
commercially valuable pelagic species connection to coral reef
ecosystems because many people eat tuna, or billfish and if they can see
that that dying coral reef ecosystems mean less tuna, or higher price
tuna, then they can relate. As an educator and outreach person I often
stuggle to match a particular connection to a particular person. I
believe that the connections are there, often several degrees seperated,
but there none-the-less and these types of personal connections make the
most powerful arguments concerning conservation.
I can tell you that the typical weekend Hawaiian fisherman couldn't care
less about divers bringing in revenue to the State if their fishing
grounds get shut down, and the diver may not care about the fisherman's
concern. In the end we are all going to have to change our behavior and
values, and make sacrifices. Acknowledging responsibilty is the first
step, then taking action. The more creative I can get about helping the
first step along, the better.
