Evaluation of Dairy Effluent Management Options Using Multiple Criteria Analysis

This article describes how options for managing dairy effluent on the Lower Murray River in South Australia were evaluated using multiple criteria analysis (MCA). Multiple criteria analysis is a framework for combining multiple environmental, social, and economic objectives in policy decisions. At the time of the study, dairy irrigation in the region was based on flood irrigation which involved returning effluent to the river. The returned water contained nutrients, salts, and microbial contaminants leading to environmental, human health, and tourism impacts. In this study MCA was used to evaluate 11 options against 6 criteria for managing dairy effluent problems. Of the 11 options, the MCA model selected partial rehabilitation of dairy paddocks with the conversion of remaining land to other agriculture. Soon after, the South Australian Government adopted this course of action and is now providing incentives for dairy farmers in the region to upgrade irrigation infrastructure and/or enter alternative industries.     

Promoting community involvement at brownfields sites in socio-economically disadvantaged neighbourhoods

Brownfields programmes provide environmental justice to distressed communities by applying private sector remediation and real estate expertise to abandoned and contaminated properties. This study examines how brownfields developers and community support organisations operating in socio-economically disadvantaged neighbourhoods work to increase awareness of projects in the community, build trust between stakeholders and create mechanisms for community members to participate in brownfields decision making. Analysis of case study data from brownfields sites in four US cities shows that developers and non-governmental organisations can play important roles in fashioning redevelopment outcomes which benefit both developers and communities. When standard required outreach efforts are combined with non-traditional community involvement mechanisms, the result is often long-term support for redevelopment projects.     

Assessing nitrogen and phosphorus removal potential of five plant species in floating treatment wetlands receiving simulated nursery runoff

The feasibility of using floating treatment wetlands (FTWs) to treat runoff typical of commercial nurseries was investigated using two 8-week trials with replicated mesocosms. Plants were supported by Beemat rafts. Five monoculture treatments of Agrostis alba (red top), Canna × generalis ‘Firebird’ (canna lily), Carex stricta (tussock sedge), Iris ensata ‘Rising Sun’ (Japanese water iris), Panicum virgatum (switchgrass), two mixed species treatments, and an unplanted control were assessed. These plant species are used for ornamental, wetland, and biofuel purposes. Nitrogen (N) and phosphorus (P) removals were evaluated after a 7-day hydraulic retention time (HRT). N removal (sum of ammonium-N, nitrate-N, and nitrite-N) from FTW treatments ranged from 0.255 to 0.738 g·m^?2·d^?1 (38.9 to 82.4% removal) and 0.147 to 0.656 g·m^?2·d^?1 (12.9 to 59.6% removal) for trials 1 and 2, respectively. P removal (phosphate-P) ranged from 0.052 to 0.128 g·m^?2·d^?1 (26.1 to 64.7% removal) for trial 1, and 0.074 to 0.194 g·m^?2·d^?1 (26.8 to 63.2% removal) for trial 2. Panicum virgatum removed more N and P than any other FTW treatment and the control in both trials. Results show that species selection and timing of FTW harvest impact the rate and mass of nutrient remediation. FTWs can effectively remove N and P from runoff from commercial nurseries.

     

What makes for good and bad neighbours? An emerging research agenda in the study of Chinese environmental politics

Tackling China’s grave environmental problems increasingly turns on questions of sub-national interjurisdictional relations. What are the conditions under which neighbouring localities cooperate in stewardship of the natural environment? What factors give rise to interjurisdictional conflict such as pollution spillovers? Through a combination of empirical and theoretical reflections, a research agenda to better understand these issues is outlined. First, China’s recent innovative approaches to the promotion of interjurisdictional cooperation are examined. An in-depth case study of interjurisdictional ecological protection ‘redline’ zones underscores the difficulties of inculcating environmental neighbourliness between local governments. Yet, a precise diagnosis of the problem remains elusive because too little is known about the underlying drivers of interjurisdictional relations in China. An analytical framework that draws insight from contemporary China studies and comparative environmental governance scholarship is offered for the study of interjurisdictional environmental relations in China.     

Review of Mathematical Programming Applications in Water Resource Management Under Uncertainty

Economic development, variation in weather patterns and natural disasters focus attention on the management of water resources. This paper reviews the literature on the development of mathematical programming models for water resource management under uncertainty between 2010 and 2017. A systematic search of the academic literature identified 448 journal articles on water resource management for examination. Bibliometric analysis is employed to investigate the methods that researchers are currently using to address this problem and to identify recent trends in research in the area. The research reveals that stochastic dynamic programming and multistage stochastic programming are the methods most commonly applied. Water resource allocation, climate change, water quality and agricultural irrigation are amongst the most frequently discussed topics in the literature. A more detailed examination of the literature on each of these topics is included. The findings suggest that there is a need for mathematical programming models of large-scale water systems that deal with uncertainty and multiobjectives in an effective and computationally efficient way.

Fit-for-Purpose Institutions? An Evaluation of Biodiversity Conservation in the Agricultural Landscape of the Tasmanian Midlands,Australia

Biodiversity loss is a globally significant problem. Institutional failure to halt this loss suggests current arrangements are not fit for the purpose of conserving biodiversity. The objective of this paper is to diagnose institutional fitness for conserving biodiversity in the Tasmanian Midlands of Australia, a highly modified agricultural landscape with critically endangered biodiversity values. This paper presents and applies a novel diagnostic framework that adopts a broad view of institutional fit, drawing on concepts from adaptive governance, institutional theory, and public administration, and finds four areas of poor fit that can guide reform efforts. The first is a narrow framing of biodiversity objectives, leading to neglect of key social and ecological concerns. Second, the interplay of current arrangements fails to buffer key economic and political drivers, and compromises adaptive capacity. Third, limited government authority and embedded power relations raise questions about the effectiveness and fairness of current approaches. Finally, the reluctance of governments to devolve authority and decision-making powers to self-organizing networks constrains adaptation. This suite of fit problems constrains achievement of biodiversity conservation, particularly in dealing with landscape multifunctionality, the need to balance private landholder rights and responsibilities, and the need to consider how to respond to emerging novel and hybrid ecosystems.     

Understanding consumer behaviour and adaptation planning responses to climate-driven environmental change in Canada's parks and protected areas: a climate futurescapes approach

Parks and protected areas are a global ecological, social and health resource visited by over 8 billion people annually. Their use can yield substantial benefits, but only if a balance between ecological integrity and sustainable visitation is struck. This research explores the potential influence of climate-driven environmental change on visitation to North America's most popular glacier, the Athabasca Glacier in Jasper National Park, Canada. Photorealistic environmental visualizations were used to gauge visitors’ perceptions of environmental change and potential impacts on consumer behaviour. Results suggest that impacts could substantially diminish the site's pull as a tourism destination. Rather than improving visitation prospects, expert-proposed adaptations underestimated the importance of perceived naturalness and contributed to further potential decline. Findings are relevant to protected areas planning and management. They suggest that a natural path to climate change adaptation is the best way to support both ecological integrity and the long-term tourism pull of protected areas.
