Selected AbstractsHydroGeo Analyst: A Data Management Solution to Ground Water and Environmental ProjectsGROUND WATER, Issue 3 2008Yongqiang Qi First page of article [source] THE HOWARD-TURNBULL NATIONAL PLAN FOR WATER SECURITY OF JANUARY 2007: RESCUE OR REJECTION?ECONOMIC PAPERS: A JOURNAL OF APPLIED ECONOMICS AND POLICY, Issue 2 2008ALISTAIR WATSON A ten-point, ten-year, ten billion dollar National Plan for Water Security was announced by the (then) Howard Government in January 2007. The Plan was supported by State governments, with the exception of Victoria. The (then) Opposition supported legislation in August 2007 to implement the Plan. The main part of the Plan was investment in off-farm and on-farm irrigation infrastructure, ostensibly to promote water use efficiency. A smaller programme was proposed for buyback of irrigation water for environmental purposes. Various economic criteria would favour the opposite emphasis. Investment by governments in private irrigation infrastructure goes against the spirit of other recent policy changes and, for economic and technical reasons, is unlikely to achieve its objectives. Buyback for environmental purposes should continue, subject to appropriate procedures and discipline in the selection of environmental projects. Recent developments highlight continuing controversies over policy and administration of the Murray-Darling Basin. [source] Stochastic Study of Solute Transport in a Nonstationary MediumGROUND WATER, Issue 2 2006Bill X. Hu A Lagrangian stochastic approach is applied to develop a method of moment for solute transport in a physically and chemically nonstationary medium. Stochastic governing equations for mean solute flux and solute covariance are analytically obtained in the first-order accuracy of log conductivity and/or chemical sorption variances and solved numerically using the finite-difference method. The developed method, the numerical method of moments (NMM), is used to predict radionuclide solute transport processes in the saturated zone below the Yucca Mountain project area. The mean, variance, and upper bound of the radionuclide mass flux through a control plane 5 km downstream of the footprint of the repository are calculated. According to their chemical sorption capacities, the various radionuclear chemicals are grouped as nonreactive, weakly sorbing, and strongly sorbing chemicals. The NMM method is used to study their transport processes and influence factors. To verify the method of moments, a Monte Carlo simulation is conducted for nonreactive chemical transport. Results indicate the results from the two methods are consistent, but the NMM method is computationally more efficient than the Monte Carlo method. This study adds to the ongoing debate in the literature on the effect of heterogeneity on solute transport prediction, especially on prediction uncertainty, by showing that the standard derivation of solute flux is larger than the mean solute flux even when the hydraulic conductivity within each geological layer is mild. This study provides a method that may become an efficient calculation tool for many environmental projects. [source] Application of multicriteria decision analysis in environmental decision makingINTEGRATED ENVIRONMENTAL ASSESSMENT AND MANAGEMENT, Issue 2 2005Gregory A. Kiker Abstract Decision making in environmental projects can be complex and seemingly intractable, principally because of the inherent trade-offs between sociopolitical, environmental, ecological, and economic factors. The selection of appropriate remedial and abatement strategies for contaminated sites, land use planning, and regulatory processes often involves multiple additional criteria such as the distribution of costs and benefits, environmental impacts for different populations, safety, ecological risk, or human values. Some of these criteria cannot be easily condensed into a monetary value, partly because environmental concerns often involve ethical and moral principles that may not be related to any economic use or value. Furthermore, even if it were possible to aggregate multiple criteria rankings into a common unit, this approach would not always be desirable because the ability to track conflicting stakeholder preferences may be lost in the process. Consequently, selecting from among many different alternatives often involves making trade-offs that fail to satisfy 1 or more stakeholder groups. Nevertheless, considerable research in the area of multicriteria decision analysis (MCDA) has made available practical methods for applying scientific decision theoretical approaches to complex multicriteria problems. This paper presents a review of the available literature and provides recommendations for applying MCDA techniques in environmental projects. A generalized framework for decision analysis is proposed to highlight the fundamental ingredients for more structured and tractable environmental decision making. [source] Multi-attribute value theory as a framework for conflict resolution in river rehabilitationJOURNAL OF MULTI CRITERIA DECISION ANALYSIS, Issue 2-3 2005Markus Hostmann Abstract Decision making in environmental projects is usually complex because of heterogeneous stakeholder interests, multiple objectives, long planning and implementation processes, and uncertain outcomes. Conflicting stakeholder interests in particular are often an important impediment to the realization and success of projects. Multiple criteria decision analysis (MCDA) methods are potentially useful for facilitating conflict resolution among stakeholder groups. However, some studies that have applied MCDA methods indicate that users are often skeptical about the value of MCDA methods and prefer the freedom of unaided decision making. We examine whether and how multi-attribute value theory (MAVT), a particular kind of MCDA, facilitates conflict resolution in environmental projects. Therefore, the MAVT method is applied to a specific river rehabilitation project in Switzerland (Thur River). The main questions are: (1) Can the MAVT method predict the final preferences of stakeholders and therefore anticipate conflicts at an early stage? (2) Do stakeholders reconsider and change their preferences after using the MAVT method? (3) If they do, does this result in more consensus-oriented decisions? We find that the principal advantage of the method in our case was not the prediction of stakeholders' final preferences, but rather the methods' ability to facilitate more consensus-oriented decisions. The paper discusses possible reasons for this finding and concludes with recommendations for future applications of the MAVT method in environmental decision making.

[source] Purchasing's Role in Environmental Management: Cross-Functional Development of Grounded TheoryJOURNAL OF SUPPLY CHAIN MANAGEMENT, Issue 3 2001Craig R. Carter SUMMARY Are government regulations a driver or barrier to environmental activities? Does greater functional involvement within a firm help to ensure the success of environmental projects? Do environmental projects improve or harm financial performance? This research finds that none of these questions can be answered with a simple "yes" or "no." Instead, this article distinguishes between successful and unsuccessful environmental projects, through an examination of not only their consequences but also their drivers and barriers and the functional interplay that occurs during their implementation. The findings result from an inductive study leading to theory grounded in the data but related to extant findings, and are based on case studies that tap the perspectives of purchasing managers and the managers in multiple, additional functional areas with whom they interact when initiating environmental projects.
