1) Introduction – tourism economics
• Tourism is a key sector in the global economy that makes
significant contributions to GDP and employment.
1) Introduction – tourism economics
• The sector is expected to grow by 4-5% in 2012, reaching
one billion tourist arrivals.
1) Introduction – tourism + environment
• Travel and tourism is also responsible for approximately
5% of global carbon dioxide emissions.
• By 2035, under a “business as usual” scenario, carbon
dioxide emissions from global tourism are projected to
increase by 130%.
1) Introduction – tourism + environment
• Environmentally and socially responsible leisure activities
have become a key issue in the development of tourism.
• See the cases of the environmental impact of the Olympics, or the
dispute over carbon taxes on flights into and out of the E.U.
• Mango in SA…
• There is a large literature on the environment, climate
change and tourism.
2) The literature
• The environment as a common pool resource:
• The earth’s atmosphere and the climate that sustains life as we
know it, is commonly owned by everyone and utilised by all – noone has to pay to live on earth!
• As a consequence, the environment suffers the effects of negative
externalities, specifically the pollution that occurs during all our
production and consumption activities.
• The externality is the difference between the private and social
costs.
• The market fails to account for the social costs since no-one owns
their share of a sustainable environment to sell to polluters and as
such no market or price exists.
2) The literature
• Are there any solutions?
• We cannot stop tourism to reduce the related pollution to zero.
• There may solutions in cooperation of coercion.
• Cooperation:
• Everyone could work together and cooperate to reduce our
consumption and the consequent pollution.
• This is an unlikely global solution as cooperation will be
undermined by the “prisoners’ dilemma”…
• Similarly, a user-pays approach may be possible, but will be limited
to voluntary contributions.
• Since on-one owns the environment it is not clear to whom
payments should be made when you pollute.
2) The literature
• Coercion:
• Government may sell pollution rights in a cap-and-trade system
and fine those that do not cooperate.
• Or they may levy carbon taxes on polluters.
• The airline industry is an example…Mango in SA
• In both cases success will depend on the ability of
government to measure the pollution, link it to the
polluters, set the tax rate and enforce it.
• These solutions also suffer from a cooperation problem,
but at a country level:
• If all governments believe that all the others will allow pollution they
will not create carbon markets or set carbon taxes.
2) The literature + tourism
• Practically speaking, the effects of human activity on the
environment, also our tourism activities, will have to be
mitigated by a combination of voluntary contributions and
compulsory taxes.
• Research into tourism and climate change has focussed
on four aspects:
• The impact of tourism on climate change.
• The impact of climate change on tourism.
• Adaptation to climate change.
• Mitigation of climate change.
2) The literature + tourism
The impact of tourism The impact of climate
on climate change

Mitigation of climate
change
2.1 The impact of tourism on climate change
• It would be difficult to quantify impact, but it can be
interesting to link travel behaviour and impact on the
environment.
• Measure travel behaviour, link to environmental impact.
• Fuel, energy, water use, recycling on holiday?
• Measure
perceptions of the
behaviour and climate change.
links
between
travel
• Many people think that because they go to a park, they are green
tourists – do they think about the impact of their 4x4, waste
products?
• Can we explain differences between perceptions and
impacts – i.e. what are the characteristics of the tourists
that care about their impact?
2.2 The impact of climate change on tourism
• Measure how the climate change has influenced travel
behaviour…
• This would be difficult at an aggregate level:

Would need a case study of an attraction that has been influenced
by some environmental change and whether this has caused a
change in tourism.
 Requires longitudinal data.
 Ski resorts, coral reefs are possible examples.
2.3 Adaptation to climate change
• You would try to measure:
• How travel behaviour has changed in response to climate change.
• How the accommodation sector has changed in response to
climate change.
• How the transport sector has changed in response to climate
change.
• The accommodation sector is the easier one to consider:
• Survey accommodation sector on the steps that they have taken to
reduce energy and water use, reduce / recycle waste.
• And what it has meant for the bottom line (or triple bottom line)
• Real numbers or perceptions?
• There are problems about asking them to think back. It would be
better to make a case study of a new programme.
• In transport, Mango might be a cool case study??
2.4 Mitigation of climate change
• Measure the willingness to pay to mitigate climate
change.
• (Determine the economic value of environmental goods).
• This can be related to transport, accommodation, events.
• Policies / strategies emphasise the polluter-pays-
principle.
• This is what we have been doing at TREES.
• The questions now become, how can we do it better, or
take it forward?
3) The literature + willingness to pay
• There are three approaches to determine how
much people are willing to pay to mitigate the
environmental impact of travel and tourism
activities:
• The travel cost method.
Try to deduce what people
• The hedonic pricing method. are willing to pay
• The contingent valuation method – ask them WTP
3.1 Travel cost method
• Some of the WTP for a "green" experience is captured by
people's travel cost.
• Approach:
• Survey visitors at different attractions, determine their travel cost.
• See how much of the variation in travel cost can be explained by
"green" characteristics of the attraction (controlling for everything
else).
• Best SA example is du Preez, Lee & Hosking on the
Recreational value of beaches in Nelson Mandela Bay.
• For this to work:
• The attractions need to be close substitutes, close to one another.
• While you ask about travel cost, you might as well as about WTP
too. Should make for an interesting comparison.
3.2 The hedonic pricing method
• Some of the WTP for a "green" experience is captured by
other prices that people pay.
• Approach:
• Survey attractions / destinations and determine their characteristics
(including "green" characteristics) as well as the prices people pay
e.g. entrance fees or price of accommodation.
• See how much of the variation in pricing can be explained by
"green" characteristics.
• No SA example that I know of (e.g. pollution and house
prices in international studies).
• For this to work:
• You need a lot of info on the characteristics of the park/lodge/hotel
and the prices that people pay.
• This could be a different way to look at the WTP for Big-5.
3.3 WTP, CV method
• Payment is hypothetical
• Valuation is contingent on the scenario presented.
• Examples:
• General approach to WTP and climate change mitigation –
Johnson & Nemet (2010).
• McKercher et al. (2010) examine the attitudes of Hong Kong
residents towards tourism and the environment, and the willingness
of residents to change their behaviours in response to climate
change.
• For focus specifically on air travelers' willingness to pay to offset
their CO2 emissions, see Brouwer et al. (2007).
• For tourists' willingness to pay for specific environmental goods,
see Casey et al. (2010) who examined WTP additional fees to
protect the coral reefs tourists were visiting in Mexico.
3.3 WTP, CV method
• Cannot just go out and ask: how much are you willing to
pay for…
• Proper CV method:
• There are NOAA guidelines
• WTP questions can be: open-ended, dichotomous choice, or
bidding games.
• The type of question determines the empirical analysis.
• You have to be careful in presenting the scenario.
• You have to try to limit cheap talk.
• You have to also ask the reasons why people are not willing to pay.
4) SA research
• Work at the NWU's research area: Tourism Research in
Economics, Environs and Society (TREES) has examined
three cases:
• WTP for carbon offsets at a sport event.
• WTP for green accommodation, wine and food at a tourist venue.
• WTP to view the Big-5 in a national park.
4.1 WTP for a green race
• For our first paper TREES went to the Two
Oceans Marathon and asked runners
whether they are willing to pay for a green race
• Our analysis showed that the carbon footprint of the
average participant is approximately 480kg of CO2, which
can be offset by planting 2.2 trees.
• We asked if they were willing to pay a higher race fee that
can be used to mitigate this impact on the environment.
• 502 athletes participated in the 2011 survey.
4.1 WTP for a green race
• Description of the data:
• Males 65%, females 35%.
• Average age 38 years.
• 57% English speaking, 26% Afrikaans.
• 32% holds a diploma or degree.
• 23% post-grad qualification.
• 27% professional occupations, 13% self-employed.
4.1 WTP for a green race
• The scenario and WTP questions:
• 11% skipped the WTP questions
• 27% indicated that they were not willing to pay.
• 62% said they would.
• Of those that were willing to pay:
• 62% said that they would pay R10
• 12% were willing to pay R30
• 19% were willing to pay R50

4.1 WTP for a green race
• Conclusions:
• We have identified some of the predictors of willingness to pay for a
green race.
• Spending may be a proxy for income, but did not yield significant
results.
• Differences between married and non-married people and between
the self-employed and other occupations may reflect differences in
discretionary income.
• Education did not have the expected positive relationship.
• The reasons why people said they were willing to pay, were
important.
4.2 WTP at a tourist venue
• In another round of research, TREES surveyed day
visitors at a tourist venue.
• Spier wine estate and hotel has a very green and
sustainable approach and we asked visitors about their
green behaviour at home and their willingness to pay for
green accommodation and organic food and wine.
• 160 visitors participated.
4.2 WTP at a tourist venue
• Description of the data:
• 60% female and 40% male.
• Most are between the ages of 25 and 41 years.
• 58% were from the Western Cape province and the rest
were visitors from further afield – approximately 26%
were foreigners (U.K., U.S., Germany).
• 62% were English speaking, 31% Afrikaans and 7%
spoke other home languages.
• 47% professionals, 23% self-employed.
4.2 WTP at a tourist venue
• Most visitors were not aware of the green initiatives at
Spier.
• But say that they would visit a wine farm that recycles,
encourages eco-friendly behaviour, makes use of energysaving technology and supports green initiatives.
• And their willingness to pay extra:
• 63% indicated that they would be willing to pay extra.
• R118 for green accommodation
• R27 for an organic meal
• R16 for an organic bottle of wine
4.2 WTP at a tourist venue
• Next we used exploratory factor analysis to identify types
of tourists based on their reported green behaviour at
home.

4.2 WTP at a tourist venue
• Conclusions:
• Again. we have identified some of the predictors of
willingness to pay for a green tourism.
• But demographic variables are not as significant as one
finds in the international literature.
• The type of tourist, classified by their green behaviour,
is what matters for willingness to pay.
4.3 WTP for the Big-5
• For our final effort we made the issue more specific.
• In stead of focusing on climate change in general or green
or sustainable tourism, we were specifically interested in
tourists' valuation of the Big-5.
• The the lion, African elephant, Cape buffalo, leopard and
the rhinoceros are some of the biggest attractions in the
national parks.
• And the opportunities to view these species in their
natural habitat is a public good.
• But what monetary value do tourists place on the Big-5?
4.3 WTP for the Big-5
• A survey was conducted in the northern part of the Kruger
National Park at the Olifants, Letaba, Mopani and Punda
Maria restcamps.
• 289 tourists participated.
• Respondents were asked what role the Big-5 plays in
their decision to visit the Park.
• And, what amount of their total spending per visit they
would allocate to the opportunity to view the Big-5 in the
Park.
4.3 WTP for the Big-5
• Description of the data:
• 69% Afrikaans speaking.
• Average age 48 years.
• 85% married.
• 65% with accompanying children.
• 48% from Gauteng province.
• 35% with diploma / degree, 28% with post-grad qualification.
• 37% earn gross annual income > R550 000
• Average spending per visit R10 300 for staying 6 nights.
• Of the spending, on average, R3 500, or about a third is allocated
to the opportunity to view the Big-5.

consideration in visiting the Park (+) WTP
4.3 WTP for the Big-5
• Conclusions:
• Education and income come out as clear predictors of willingness
to pay.
• Can Park management leverage this for the protection and
conservation of for example Rhinos?
• Four hundred and forty eight (448) rhinos were illegally killed across
South Africa in 2011.
• The poaching of rhinos in the Kruger National Park accounted for 252 of
the 2011 total.
• South Africa already lost 168 rhinos in 2012.
5) A way forward?
• Impact of tourism on climate change:
• Examine travel behaviour, link to impact on environment.
• Examine tourists' perceptions of their impact.
• Identify types of green tourists.
• Impact of climate change on tourism?
• Adaptation to climate change:
• Accommodation sector case studies.
• Managers' perceptions?
• Document the process, benefits, costs of going green?
• WTP climate change mitigation:
• Doing more of the same will not yield the high-impact publications.
• My manifesto…
5) My "green" tourism economics
research manifesto!
5) My "green" tourism economics

Conclusions
• Tourism and the environment.
• What can economists add?
• Experiments and randomized control trials.
• It is the type of tourist that matters.
• The importance of awareness and education.
