The economic value of ecosystem services in the Great Barrier Reef: our state of knowledge

This article reviews literature relating to the Great Barrier Reef (GBR) and aims to assess the current state of knowledge about (1) the “value” of ecosystem services (ES) provided by the GBR and (2) the way in which activities that are carried out in regions adjacent to the GBR affect those values. It finds that most GBR valuation studies have concentrated on a narrow range of ES (e.g., tourism and fishing) and that little is known about other ES or about the social, temporal, and spatial distribution of those services. Just as the reef provides ES to humans and to other ecosystems, so too does the reef receive a variety of ES from adjoining systems (e.g., mangroves). Yet, despite the evidence that the reefs ability to provide ES has been eroded because of recent changes to adjoining ecosystems, little is known about the value of the ES provided by adjoining systems or about the value of recent changes. These information gaps may lead to suboptimal allocations of resource use within multiple realms.

Does ECO certification deliver benefits? An empirical investigation of visitors' perceptions of the importance of ECO certification's attributes and of operators' performance.

Certification is highlighted as a key sustainable tourism management tool. Yet, very little is known about visitors’ perceptions of such schemes. This is an important gap: the success of certification schemes depends on consumers’ confidence in the quality of products and services that the schemes endorse. This paper surveyed 610 visitors to the Wet Tropics World Heritage Area and surrounds in Queensland, Australia about (1) the perceived importance of various attributes of the ECO certification scheme; and (2) the perceived performance of operators based on those attributes. Data analysis identified aspects of ECO certification and of operator performance that may need improvement. It found that importance of attributes varied across products and visitor groups; at accommodations, most attributes were perceived to be important, Nature (as an aesthetic experience) and Marketing being more important than others, while at attractions and on tours, visitors were indifferent. Younger visitors rated Environment and Conservation more highly than their older counterparts and females rated Conservation more highly than males. Visitors – notably at accommodations – considered that ECO certified operators were performing “better” than non-ECO certified operators on many attributes. How these visitor perceptions translate into reality remains an important topic for future research.

The significance of environmental values for destination competitiveness and sustainable tourism strategy making: insights from Australia's Great Barrier Reef World Heritage Area

Sustainable destinations must deliver products that perform better than their competitors and at the same time protect key environmental drawcards. This research explores the environmental–economic interface of a major destination, both as a case study in how to approach this complex relationship and as a contribution to the methodology of tackling the need for understanding competitive pressures as part of sustainable tourism strategy creation. Using the Great Barrier Reef World Heritage Area (GBRWHA) as an example, the paper assesses 21 key environmental values, including Indigenous culture, against market-based factors, in terms of their importance for visitors as regional drawcards, satisfaction with them and the way in which changes in them might affect trip numbers and duration across different regions. While the natural values of the GBRWHA are found to be the most important drawcards, satisfaction scores were significantly lower than importance scores for a number of these values. Visitors responded more negatively to the prospect of environmental degradation than to the prospect of a 20% increase in local prices: the detailed impact depends, however, on location and visitor mix. Clear ocean, healthy coral reefs, healthy reef fish, and lack of rubbish were the top four most important values.

The role the Great Barrier Reef plays in resident wellbeing and implications for its management.

Improvements in human wellbeing are dependent on improving ecosystems. Such considerations are particularly pertinent for regions of high ecological, but also social and cultural importance that are facing rapid change. One such region is the Great Barrier Reef (GBR). Although the GBR has world heritage status for its ‘outstanding universal value’, little is known about resident perceptions of its values. We surveyed 1545 residents, finding that absence of visible rubbish; healthy reef fish, coral cover, and mangroves; and iconic marine species, are considered to be more important to quality of life than the jobs and incomes associated with industry (most respondents were dissatisfied with the benefits they received from industry). Highly educated females placed more importance on environmental non-use values than other respondents; less educated males and those employed in mining found non-market use-values relatively more important. Environmental non-use values emerged as the most important management priority for all.

Using measures of wellbeing for impact evaluation: proof of concept developed with an Indigenous community undertaking land management programs in northern Australia

Abstract Combining insights from literature on the Theory of Change, Impact Evaluation, and Wellbeing, we develop a novel approach to assessing impacts. Intended beneficiaries identify and rate factors that are important to their wellbeing, their satisfaction with those factors now, and before an intervention. Qualitative responses to questions about perceived changes and causes of change are linked to quantitative data to draw inferences about the existence and/or importance of impact(s). We use data from 67 Ewamian people, in a case study relating to Indigenous land management, to provide proof of concept. ‘Knowing that country is being looked after’ and ‘Having legal right/access to the country’ were identified as important to wellbeing, with perceptions that Native Title determination, declared Indigenous Protected Area and associated land management programs have had a significant and positive impact on them. Further method testing might determine the utility of this approach in a wide range of settings.

If climate change means more intense and more frequent drought, what will that mean for agricultural production? A case study in Northern Australia

ABSTRACT We examine the influence of drought and a variety of factors on agriculture in Northern Australia. Assuming constant prices, and using data collected from northern land managers, we estimate a Cobb–Douglas production function and use coefficients from the model to estimate the financial losses associated with drought. We find that drought-affected properties earn about half as much as other ‘similar’ properties. We then ask: How much does that ‘cost’ the industry, on average, and how would those costs change if droughts were to become more, or less widespread under climate change? Our estimates indicate that under the current climatic regime, the Northern Australian agricultural industry loses, on average, about 19% of output to drought each year: this could fall to 10% or rise to 40% under current climate projections. Although focused on Northern Australia, the findings have wider implications for management and adaption, given the magnitude of impacts and their likelihood to extend beyond the ‘official’ end of drought. Investments in climate-proof crops, on-farm management techniques and financial arrangements to help producers deal with a range of climatic risks, for example, should thus be priorities.
