Terrestrial pollutant runoff to the Great Barrier Reef: An update of issues, priorities and management responses

The Great Barrier Reef (GBR) is a World Heritage Area and contains extensive areas of coral reef, seagrass meadows and fisheries resources. From adjacent catchments, numerous rivers discharge pollutants from agricultural, urban, mining and industrial activity. Pollutant sources have been identified and include suspended sediment from erosion in cattle grazing areas; nitrate from fertiliser application on crop lands; and herbicides from various land uses. The fate and effects of these pollutants in the receiving marine environment are relatively well understood. The Australian and Queensland Governments responded to the concerns of pollution of the GBR from catchment runoff with a plan to address this issue in 2003 (Reef Plan; updated 2009), incentive-based voluntary management initiatives in 2007 (Reef Rescue) and a State regulatory approach in 2009, the Reef Protection Package. This paper reviews new research relevant to the catchment to GBR continuum and evaluates the appropriateness of current management responses.

Participatory scenario planning in place-based social-ecological research: insights and experiences from 23 case studies

Participatory scenario planning (PSP) is an increasingly popular tool in place-based environmental research for evaluating alternative futures of social-ecological systems. Although a range of guidelines on PSP methods are available in the scientific and grey literature, there is a need to reflect on existing practices and their appropriate application for different objectives and contexts at the local scale, as well as on their potential perceived outcomes. We contribute to theoretical and empirical frameworks by analyzing how and why researchers assess social-ecological systems using place-based PSP, hence facilitating the appropriate uptake of such scenario tools in the future. We analyzed 23 PSP case studies conducted by the authors in a wide range of social-ecological settings by exploring seven aspects: (1) the context; (2) the original motivations and objectives; (3) the methodological approach; (4) the process; (5) the content of the scenarios; (6) the outputs of the research; and (7) the monitoring and evaluation of the PSP process. This was complemented by a reflection on strengths and weaknesses of using PSP for the place-based social-ecological research. We conclude that the application of PSP, particularly when tailored to shared objectives between local people and researchers, has enriched environmental management and scientific research through building common understanding and fostering learning about future planning of social-ecological systems. However, PSP still requires greater systematic monitoring and evaluation to assess its impact on the promotion of collective action for transitions to sustainability and the adaptation to global environmental change and its challenges.

Landscape change in the multi-functional countryside: a biographical analysis of farmer decision-making in the English high weald

There is growing recognition that the landscape implications of agricultural restructuring are complex, location specific and subject to various feedback effects. This paper explores how the economic decline of mainstream farming in the English High Weald is redefining the relationship between agriculture and the landscape, encouraging existing farmers to diversify their income base but also creating opportunities for new forms of land occupancy and management in a multi-functional countryside. Through a biographical analysis of a range of different types of land manager, it is illustrated how attitudes to land use and the occupancy of rural land are changing, distinguishing between holdings that are still seen primarily as sites of production by their farming family occupiers and those that are coming to be regarded chiefly as spaces for living by a new category of lifestyle occupier. The implications of this differentiation of the stakeholder community for future landscape management in the United Kingdom and the European Union are explored.

Landscapes Toolkit: an integrated modelling framework to assist stakeholders in exploring options for sustainable landscape development

At present, stakeholders wishing to develop land use and management change scenarios at the landscape scale and to assess their corresponding impacts on water quality, biodiversity and economic performance, must examine the output of a suite of separate models. The process is not simple and presents a considerable deterrent to making such comparisons and impedes the development of more sustainable, multifunctional landscapes. To remedy this problem, we developed the Landscapes Toolkit, an integrated modelling framework that assists natural resource managers, policy-makers, planners and local communities explore options for sustainable landscape development. The Landscapes Toolkit links spatially-explicit disciplinary models, to enable integrated assessment of the water quality, biodiversity and economic outcomes of stakeholder-defined land use and management change scenarios. We use the Tully–Murray catchment in the Great Barrier Reef region of Australia as a case study to illustrate the development and application of the Landscapes Toolkit. Results show that the Landscapes Toolkit strikes a satisfactory balance between the inclusion of component models that sufficiently capture the richness of some key aspects of social-ecological system processes and the need for stakeholders to understand and compare the results of the different models. The latter is a prerequisite to making more informed decisions about sustainable landscape development. The flexibility of being able to add additional models and to update existing models is a particular strength of the Landscapes Toolkit design. Hence, the Landscapes Toolkit offers a promising modelling framework for supporting social learning and adaptive management through participatory scenario development and evaluation as well as being a tool to guide planning and policy discussions at the landscape scale.

Integrating social and ecological knowledge for planning sustainable land- and sea-scapes: experiences from the Great Barrier Reef region, Australia

The integration of social and ecological knowledge has been identified as one of the key issues and research priorities in landscape ecology. However, research into the tools and processes that support knowledge integration for planning sustainable land- and sea-scapes is largely lacking. To fill this gap, Bohnet and Smith (Landsc Urban Plan 80:137–152, 2007) developed a social-ecological planning framework based on a holistic landscape concept which I applied in the Tully–Murray basin to test the framework’s transferability and effectiveness for knowledge integration in a water quality improvement planning context in the Great Barrier Reef (GBR) region, Australia. In this paper I present the context in which the Tully Water Quality Improvement Plan (WQIP) was developed, the tools and processes applied during the three planning stages to achieve knowledge integration, and the results from this exercise. I then discuss the transferability and effectiveness of the framework using criteria identified to assess collaborative planning processes, outputs and outcomes, such as collaborative science and social and political capital. While many social outcomes such as the creation of partnerships between multiple-stakeholders, including Traditional Owners, local farmers, industry, government, community groups, schools, and the wider public, have been achieved, the research also highlights some of the challenges related to multiple-stakeholder relations. Further research into the roles and responsibilities of multiple-stakeholders for knowledge integration in developing and managing sustainable land- and sea-scapes is recommended.

Landscape dynamics in Germany

Modern lifestyles, new demographic trends, and the expansion of the European Community are changing the European countryside. At stake are cultural landscapes, their richness in wildlife, historical interest, scenic beauty, and the recreational opportunities they provide. Visible phenomena of change are symptoms of a growing socio-economic and ecological disparity between different regions. Agreements on AGENDA 2000 European policy provide a new platform for regional and agricultural development. The paper explores which landscape dynamics are in store. Employing examples from rural Germany, the paper presents corridors of possible futures for unique, and at the same time, dynamic places. Modern strategies of landscape and urban planning are discussed which aim at closer co-operation between a multitude of stakeholders, policy makers, planners, and other agents of change. Methods and tools are needed to build consensus among ever increasing numbers of participants representing potentially wide ranges of values.

Community uses and values of water informing water quality improvement planning: a study from the Great Barrier Reef region, Australia

Community participation has gained widespread recognition in water management and planning for its poten- tial to inform management plans and gain community support for actions that are aligned with the communitys water values. However, the practical application of community participation remains challenging as there is no consensus on who should be involved and why. During a participatory research project to inform the Tully Water Quality Improvement Plan (WQIP), the local community was involved in qualitative interviews and workshops to identify the water uses and values in the Tully basin. The results showed that these waters are extensively used and valued via a wide range of activities and that water is more than an economic good. All participants valued the aquatic ecosystems, which provide the basis for setting the most stringent water quality objectives (WQOs). Moreover, the results showed that many of the current uses and values of waters are under serious threat and that some uses and values have been lost over time. These findings informed the setting of the WQOs for the Tully WQIP to protect and re-establish the water uses and values that the local community supports.

Water Quality Degradation of Coastal Waterways in the Wet Tropics, Australia

The Wet Tropics region of north Queensland has outstanding environmental values, contains the highest biological diversity in Australia, and borders the Great Barrier Reef. Comparable to other tropical areas worldwide, increasing urban and agricultural development in the Wet Tropics has caused concerns with respect to ecosystem degradation due to poor water quality in freshwater reaches and marine environments. Key issues currently identified in the Wet Tropics include erosion and subsequent stream turbidity and sedimentation, nutrients from erosion and fertiliser use and pesticide residue contamination. Issues such as reduced dissolved oxygen, acid sulfate soil runoff, and biological factors such as weed infestation, reduced and degraded riparian vegetation condition, and flow modification have also been identified. These issues mainly arise from agricultural activities with lesser effects from urban development. Management of pollution to improve in-stream water quality requires a long-term monitoring program to characterize water quality conditions over different flows and seasons. This type of monitoring program is underway; however, the focus is on the Great Barrier Reef and does not fully consider freshwater ecosystem health. Another major issue is the lack of a fully developed conceptual framework that links changed land use to water quality and subsequently to aquatic ecosystem health. In this paper, we establish the current level of water quality knowledge in the Wet Tropics while outlining a conceptual framework connecting changing land management practices and their effects to water quality and to ecosystem health.

Lessons Learned from Public Participation in Water Quality Improvement Planning: A Study from Australia

The value of public participation in water planning and management has been recognized in recent years; however, questions remain regarding which processes and factors contribute to appropriate participation. In this article I analyze the participatory processes employed to develop a water quality improvement plan (WQIP) for the Tully–Murray catchment in northeastern Australia using Smiley et al.s (2010) analytical framework for appropriate public involvement. Three key lessons are drawn from this analysis, which are suggested to guide future research. First, to achieve participation by all relevant stakeholders, participation needs to be institutionalized. Second, the role and relevance of scientific and local knowledge and values for making decisions need clarification. Third, how conflicts, in particular conflicts over competing water uses and values, can be addressed and effectively dealt with deserves further research attention.

Young People Envision the Future of Their Local Area: An Explorative Study From the Wet Tropics, Australia

In this article we present the results from an exploratory study conducted in the Wet Tropics in Australia. The study was initiated as part of a larger research program to support the development of a water quality improvement plan. Seven schools were invited to participate in this study. Students were asked to develop visions for the future of their local area. Results suggest that integrating a futures perspective into formal educational programs provides a mechanism to connect students with their local community and their local environment, and at the same time, encourages critical thinking and environmental citizenship beyond the classroom.
