Establishing international best practice principles for impact assessment teaching and training

Best Practice Principles for Impact Assessment (IA) Teaching and Training were developed for the International Association for Impact Assessment (IAIA). Research conducted throughout 2018 and 2019 encompassed seven iterative steps: an initial practitioners workshop; comprehensive review of 40 years of literature on teaching IA; initial survey of teachers and trainers; follow-up interviews; development of draft set of principles; final survey of the importance of the draft principles to university teachers and professional development trainers in IA; and a final workshop at IAIA19. The resulting principles are grouped in relation to content (what is taught), pedagogy (how content is taught) and skills development. From 29 draft principles, those identified as ‘Extremely Important’ or Very Important’ (28 in total) in the final survey were included in the Principles published by IAIA. Differences in relative importance of the principles are apparent between teachers and trainers, reflecting their different teaching contexts and objectives. It is hoped that the principles can contribute to more consistent and more effective IA education, contributing in turn to improved IA practice

Making it personal: Developing sustainability leaders in business

Sustainability challenges present organizations in many industries with the need to change. Leaders are critical to the process of becoming more sustainable, and yet leading change for sustainability requires new competencies. Learning at an individual level is central to developing new competencies; however, there has been limited focus to date in the literature on corporate sustainability on how leaders can learn to respond to sustainability challenges. In this article, we focus on how managers learn to become sustainability leaders in their organizations by exploring the phenomenon of experiential learning programmes. We do this by interviewing participants and organizers of four programmes about what they learned and how the programmes helped them achieve these learning outcomes. We find that the programmes supported the development of understanding, personal connection, and empowerment to act for sustainability. In particular, making sustainability personal for participants led to deep learning in each of these three areas. We contribute to conversations in the corporate sustainability literature on the potential for individuals within organizations to respond to and connect with sustainability issues in different ways. We also contribute to the literature on education for sustainability and provide practical implications for experiential learning programmes in business and business education

Exploring the relationship between context and effectiveness in impact assessment

Impact Assessment (IA) has been adopted worldwide typically to ensure the achievement of its goal(s), which might be one or more of sustainable development, environmental policy integration, and democratic governance. Researchers have developed and applied effectiveness frameworks in order to evaluate whether IA achieves its goal(s). The application of these frameworks often identifies some areas of ineffectiveness, and the frameworks are rarely transferable to other cases either within or across different jurisdictions, which makes national and international comparisons problematic. Context is frequently cited as a reason why ineffectiveness is identified in a case, and yet context is not clearly understood in relation to effectiveness. Our aim in this paper is to unpack the notion of context in order to better understand how IA can achieve its goal(s). Based on literature review and a subsequent conceptualisation of context drawing, for the first time, on Integral Theory, we propose that the notion of context can be understood as a range of mediators, which act either as enablers or barriers to the ability of IA to deliver its goal(s). It is these mediators which lead to very different IA system performance in terms of goals achievement, despite applying similar procedural steps. Our conceptualisation provides a significant contribution as it clarifies the validity of claims about contextual elements in the literature, explains the nature of different elements of context, provides a framework with which they can be meaningfully considered and makes an initial attempt at identifying strategies for ensuring mediators act as enablers rather than barriers. It also potentially serves to help unify literature on the meaning of context for IA effectiveness, effectiveness dimensions, and causation in IA, thus providing clarity over the challenges of goals achievement and the appropriateness of capacity development interventions

Global megatrends and their implications for environmental assessment practice

This paper addresses the future of environmental assessment (EA) practice in light of a rapidly changing world. We apply a literature review-based methodology to firstly identify key global megatrends and then reflect upon the implications for EA practice based on some known challenges. The key megatrends identified are synthesised into six categories: i) demographics, ii) urbanization, iii) technological innovation, iv) power shifts, v) resource scarcity and vi) climate change. We then discuss the implications of these megatrends for EA practice against four known EA challenges namely: dealing with i) complexity and uncertainty, ii) efficiency, iii) significance and iv) communication and participation. Our analysis suggests important implications for EA practice such as: increased difficulties with accuracy of prediction; the need for facilitative adaptation; an increase in the occurrence of unexpected events; higher expectations for procedural efficiency; challenges with information and communication management; dealing with significance judgements; and mitigation amidst resource scarcity and increasing pressures on earth systems. The megatrends underscore the need for continued evolution of EA thinking and practice, especially moving away from seeking a predictable single future or outcome towards the possibility of multiple scenarios with associated adaptability and enhanced system resilience capable of responding to rapid change

Distilling and applying criteria for best practice EIA follow-up

Follow-up is an essential component of Environmental Impact Assessment (EIA) if the success of EIA in improving the sustainability of a project once implemented is to be determined. This paper aims to establish universally-applicable criteria for EIA follow-up to evaluate project performance once assessed and underway. A suite of 24 criteria is derived from EIA follow-up best practice principles published by the International Association for Impact Assessment. The criteria are categorized according to the five dimensions of EIA follow-up: monitoring, evaluation, management, communication and governance. Posed as questions, the criteria support qualitative assessments of EIA follow-up performance for a project. Through application of the criteria to a case study currently under construction (the Shell Cove Marina project in eastern Australia), we found they provided an effective basis for a document review process delivering a short but informative account of the follow-up performance of the case study. The more robust evaluation of some of the criteria, particularly in the governance category, would require supplementary techniques such as interviews

A non-hybrid method for the PDF equations of turbulent flows on unstructured grids

In probability density function (PDF) methods of turbulent flows, the joint PDF of several flow variables is computed by numerically integrating a system of stochastic differential equations for Lagrangian particles. A set of parallel algorithms is proposed to provide an efficient solution of the PDF transport equation, modeling the joint PDF of turbulent velocity, frequency and concentration of a passive scalar in geometrically complex configurations. An unstructured Eulerian grid is employed to extract Eulerian statistics, to solve for quantities represented at fixed locations of the domain (e.g. the mean pressure) and to track particles. All three aspects regarding the grid make use of the finite element method (FEM) employing the simplest linear FEM shape functions. To model the small-scale mixing of the transported scalar, the interaction by exchange with the conditional mean model is adopted. An adaptive algorithm that computes the velocity-conditioned scalar mean is proposed that homogenizes the statistical error over the sample space with no assumption on the shape of the underlying velocity PDF. Compared to other hybrid particle-in-cell approaches for the PDF equations, the current methodology is consistent without the need for consistency conditions. The algorithm is tested by computing the dispersion of passive scalars released from concentrated sources in two different turbulent flows: the fully developed turbulent channel flow and a street canyon (or cavity) flow. Algorithmic details on estimating conditional and unconditional statistics, particle tracking and particle-number control are presented in detail. Relevant aspects of performance and parallelism on cache-based shared memory machines are discussed.Comment: Accepted in Journal of Computational Physics, Feb. 20, 200

Measuring Kruger visitors’ place attachment to specific camps

Tourists become emotionally, physically and socially attached to national parks as they become familiar with the park’s settings and endow it with value. Researchers have pointed out that place attachment leads to environmentally responsible behaviour and higher levels of visitor satisfaction. Therefore, increasing the level of attachment that visitors feel is vital for park and camp managers, and to do so a greater understanding of the various dimensions of it is needed. While attachment to parks has been evaluated previously, attachment to specific camps in parks has not been done. The main purpose of this research study was to measure the extent to which visitors to the Tamboti and Satara camps in the Kruger National Park feel attached to these camps. We also determined whether differences exist between visitors in terms of the level of attachment that they experience towards these camps. Finally, we established the variables that influence place attachment. A self-administered paper-based questionnaire was distributed to visitors to the Tamboti and Satara camps, with 201 questionnaires completed. The results show that visitors generally have a neutral feeling towards the camps. Furthermore, the differences in visitors’ levels of attachment could be attributed to their nationality, wild card membership and frequency of visits. Various managerial implications are drawn and recommendations made on how to increase place attachment to these camps. Conservation implications: This results indicate that visitors do not show particularly strong attachment towards Tamboti and Satara. Recommendations are given for camp managers to increase place attachment to the camps. If camp managers can succeed in fostering stronger levels of attachment to these camps, visitors are more likely to display environmentally responsible behaviour in the camps, with positive conservation implications

Understanding visitor expectations for responsible tourism in an iconic national park: Differences between local and international visitors

A survey on expectations for responsible tourism was administered to 201 visitors to the iconic Kruger National Park, comprising 55% South African nationals and 45% international tourists. Using Likert-scale questions, respondents were invited to indicate the level of importance they attached to 38 aspects of responsible tourism. Space was also provided for open comments. Conservation of biodiversity and geological features were rated very highly by both groups while aspects related to the local community, though considered important overall, were ranked lowest overall, with international tourists rating this category as more important than South Africans. Aspects related to traffic and access were rated to be more important by South Africans, probably because they mostly self-drive while international visitors rely more on organised game drives. Visual and aesthetic features of camps, as well as energy, water and waste management were all considered very important by all respondents, with members of both groups making further suggestions for improvement. This suggests that visitors are supportive of low environmental impact tourism in the Kruger National Park. In light of the strategic goal of South African National Parks to increase visitor numbers, it will be important that this goal is achieved without compromising sound environmental performance

PDF model based on Langevin equation for polydispersed two-phase flows applied to a bluff-body gas-solid flow,

The aim of the paper is to discuss the main characteristics of a complete theoretical and numerical model for turbulent polydispersed two-phase flows, pointing out some specific issues. The theoretical details of the model have already been presented [Minier and Peirano, Physics Reports, Vol. 352/1-3, 2001 ]. Consequently, the present work is mainly focused on complementary aspects, that are often overlooked and that require particular attention. In particular, the following points are analysed : the necessity to add an extra term in the equation for the velocity of the fluid seen in the case of twoway coupling, the theoretical and numerical evaluations of particle averages and the fulfilment of the particle mass-continuity constraint. The theoretical model is developed within the PDF formalism. The important-physical choice of the state vector variables is first discussed and the model is then expressed as a stochastic differential equation (SDE) written in continuous time (Langevin equations) for the velocity of the fluid seen. The interests and limitations of Langevin equations, compared to the single-phase case, are reviewed. From the numerical point of view, the model corresponds to an hybrid Eulerian/Lagrangian approach where the fluid and particle phases are simulated by different methods. Important aspects of the Monte Carlo particle/mesh numerical method are emphasised. Finally, the complete model is validated and its performance is assessed by simulating a bluff-body case with an important recirculation zone and in which two-way coupling is noticeable.Comment: 23 pages, 10 figure
