A responsibility–accountability framework for private sector use of a World Heritage Area

The Great Barrier Reef (GBR) is a natural asset of global significance, spanning 2600?km’s along the Australian coastline. On the southern tip of the GBR is the Gladstone region, where high levels of industrial activity have been juxtaposed with the natural wonder, and World Heritage Listed, GBR. Given these competing local priorities, this research explores local perceptions of the GBR and its management. Exploratory analysis of 38 interviews with residents and stakeholders from Gladstone revealed a potential incongruence between environmental concern and support for more stringent management of the tourism and resources sectors on the GBR. A responsibility–accountability framework (RAF) for managing the use and protection of the GBR is developed by drawing on current theoretical frameworks and the results of the interviews. Importantly the framework highlights the importance of business responsibility combined with monitoring and control mechanisms to ensure accountability and to deliver transparency, education and partnership. Future research should apply the RAF for testing and application in other marine World Heritage Area contexts.     

PHYSICAL PROCESSES AND EUTROPHICATION1

ABSTRACT: Biological responses to physical-chemical processes were examined in Toronto and Hamilton Harbours of Lake Ontario. Nutrient loadings to the harbors are large and are of similar magnitude, yet the trophic conditions of the harbors were considerably different. Lake oscillations were found to determine the flushing rates and environmental stability of the harbors. LOW residence times (<10 days) resulted in homogenous chemical conditions in Toronto Harbour, and prevented the establishment of large phytoplankton crops. The longer retention time of Hamilton Harbour permitted the establishment of huger phytoplankton crops. There probably exists a critical retention time where nutrient input events persist for a sufficient period of time for the algal community to adapt to and exploit the environmental conditions of nearshore areas.     

Exploring the Crowding–Satisfaction Relationship in Recreational Boating

Along with the growing boating population and the number of boats in use on limited inland waterways, boater expectations of setting density, safety perceptions, and the associated impacts on their experience (e.g., satisfaction) are becoming increasingly important. The primary purpose of this article was to explore a recreational boating crowding–satisfaction model derived from previous work using safety and enjoyment as mediating variables. We also tested our crowding–satisfaction model among day and overnight users. Our analysis revealed no significant difference between day and overnight users for any of the relationships tested in our model. Our final model indicated as respondents’ expectations for seeing people increased along with their feelings of being crowded, they were more inclined to consider the conditions on the lake as being unsafe. They were also more inclined to indicate that the number of people they had seen on the lake detracted from their boating experience. Respondents’ satisfaction was tied to their perceptions of crowding. Mediating variables illustrated that the relationship was conditioned by perceptions of safety and enjoyment. Analysis of the indirect effect observed in our study illustrate that when the number of people seen on the lake exceed respondents’ expectations, their perceptions of safety and enjoyment both decline, resulting in lower satisfaction. These findings have implications for managing recreational boating use on inland lake systems. Given the role played by expectations in our model, efforts to communicate with boaters about conditions on these waterways is important for helping them plan their boating experience and avoid situations they consider unsafe or unsatisfactory.
