Liveability as determinant of health: Testing a new approach for health impact assessment of major infrastructure

Major urban infrastructure projects are intended to alter the built, human ecology for the better. Even when they are not labelled as health projects, arguably they should produce public health benefits that are commensurate with their scale, particularly when they are publicly funded. Health impact assessment (HIA) is an established method of evaluating major infrastructure projects using a determinants of health equity lens. HIA explicitly puts health front and centre to ask, ‘How should the proposed infrastructure project be altered to improve the determinants of health equity?’ There are well-established HIA protocols, but few provide a framework for scoping possible impacts. Given interest in the concept of liveability we introduce an exhaustive, evidence-based framework of 11 liveability domains for HIA. We then test the framework by scoping the impacts of the Upfield Level Crossing Removal (LXR) project in Melbourne, Australia to hypothesise its impacts on health. Scoping this case study suggests that many domains will be affected in complex ways, some positively and some negatively, exemplifying the potential for the framework to detect major infrastructures' pervasive impacts on determinants of health. The paper includes a plan to validate the liveability framework with empirical research in the HIA assessment stage. The paper concludes with a discussion of the contribution and usefulness of the liveability domains as a framework for structuring HIA and for building its profile, thus advancing the discipline, and helping to ensure that all major infrastructures constitute a prudent investment in public health.     

An integrated method for the assessment of social sustainability in public-works procurement

Today, critical deficiencies hinder the effective inclusion of social criteria in public-works procurement. The primary reasons for this are the lack of information and objective social assessment methods in the construction industry. Hence, this paper proposes a method to assist agencies in including indicators and objective assessments of social sustainability in public-works procurement. This method applies to civil engineering projects in the infrastructure life-cycle construction stage using design-bid-build delivery. Eight social categories and 22 factors are organized into two organizational levels (project and company). Quantitative and semi-quantitative indicators are proposed to assess the social commitment of construction companies in their organizations and projects. Additionally, two aggregation formulas are established as assessment criteria in public-works procurement. The results highlight that the indicators' importance in assessing social commitment in a project can be defined depending on the local context. Moreover, the method to assess corporate social responsibility can also measure and compare a company's performance, regardless of size. The proposed method can be used in procurement procedures, helping public-works procurers develop transparent decision processes.     

Evolution of online public opinions on social impact induced by NIMBY facility

Public opinions play a pivotal role in public participation and decision-making in mega construction projects. The rise of technology and social media has facilitated the online public debate on social impacts derived from mega construction projects. This study presents a novel approach to analyze the evolution of public opinions through social media. This analysis framework covers: the temporal patterns of online messages, evolution of frames, and evolution of users. Such novel approach is employed to analyze the evolution of online public opinions on a mega construction project. Content analysis and a number of curve fitting methods were innovatively combined. Results show that social event had dual diffusion cycles while the formation mechanism of each cycle was completely different. The key parameters of Bimodal Gaussian model can depict the characteristics of online diffusion of public opinions. Elites and media organizations form the crucial nodes in the online diffusion process. The sequence of each frame and their share in the total number of frames are determined by preference of elites and media organizations. These findings are useful to develop effective strategy for public engagement, and to prevent and intervene the social conflicts.     

Online rumor propagation of social media on NIMBY conflict: Temporal patterns,frameworks and rumor-mongers

The rapid development of social media has accelerated the online rumor propagation, making social conflicts more intense during the development of NIMBY facilities. The “fake news” issue is not new, as the consequences will be amplified when the fakery spreads on social media as online rumors. However, few studies have been undertaken on the online public opinion, especially the rumor propagation on NIMBYism. This study collects data related to the anti-PX demonstration in Maoming city in 2014 on the Weibo platform. To form the rumor text library, qualitative research method is adopted to encode the collected data. Based on the social amplification of risk framework, three sub-frameworks are proposed in this study and statistical method is used to analyze the topics of rumors. Meanwhile, the textual content analysis and impact factor analysis is employed to examine the semantic features of rumor texts and the key role of rumor-mongers respectively. The results show that there are three main propagation lifecycles of rumors while the topics of rumors vary according to the cycle. Rumors belonging to each framework have diverse trend and the assessment framework is dominant throughout the process. “Individuals” and “Elites” are the main force of rumor spreading, and “Media practitioners” are the opinion leaders. These findings are useful for governments to establish a rumor detection system so that official information can be released and rumors can be refuted without delay. Meanwhile, the cooperation with the opinion leaders in online rumor propagation should be strengthened. In addition, a scientific popularization and timely notification of project progress is recommended prior to the development of NIMBY facility.     

Assessment of flood adaptive capacity of urban areas in Thailand

Urban floods have a significant impact on the economy, livelihoods, and daily activities. Despite extensive research on flood adaptation, there is a lack of consensus on ways to assess flood adaptive capacity. This research thus proposes an assessment framework of flood adaptive capacity of urban residents in flood-prone areas. The indicators are based on six components: economic resources, social capital, awareness and training, technology, infrastructure, and institutions and policies. The relevancy of the indicators was evaluated by experts in related fields, and a questionnaire was developed to collect data from a random sample of 230 households in 10 flood-prone municipalities in Thailand. Statistical analysis and structural equation modeling were subsequently performed to validate the components and indicators, and a flood-adaptability questionnaire was constructed. As a trial implementation, the questionnaire was applied to a target flood-prone municipality, Phetchaburi, to assess its adaptive capacity to flooding, expressed as flood adaptive capacity index. The adaptive capacity of Phetchaburi municipality to flooding was found to be high indicating the improvement in economic resources and infrastructure components. These findings reveal that the proposed framework is suitable for assessing the flood adaptive capacity of urban residents and useful for integrated flood risk assessment and management.     

Phase-based externality analysis for large hydropower projects

The global pressure of reducing greenhouse gas emission with an increasing energy demand has promoted the development of hydropower projects. However, these projects are always involved with controversial issues even when providing great positive externalities. This calls for more comprehensively quantitative analysis of hydropower project externalities. This paper establishes an analysis framework for hydropower project externalities based on the Life Cycle Assessment methodology and the economic valuation of hydropower externalities, and then applies the framework to the assessment of the Three Gorges Project and the Xiluodu Project as cases. The results indicate that: (1) hydropower project externalities are multi-component and dynamic in different phases of project life cycle; (2) the construction of large hydropower projects is beneficial for social welfare promotion, but the enhancement doesn't appear immediately at the startup but with a lag; and (3) along the life cycle of a hydropower project, negative externalities are prominent in the early phases while positive ones account for a major proportion in the late phases, calling for special attention to risk management during the construction and benefit allocation management during project operation. The results and recommendations of this paper can also be applied to other types of public or private projects for better social performance.     

A Strategic Project Appraisal framework for ecologically sustainable urban infrastructure

Actors in the built environment are progressively considering environmental and social issues alongside functional and economic aspects of development projects. Infrastructure projects represent major investment and construction initiatives with attendant environmental, economic and societal impacts across multiple scales. To date, while sustainability strategies and frameworks have focused on wider national aspirations and strategic objectives, they are noticeably weak in addressing micro-level integrated decision making in the built environment, particularly for infrastructure projects. The proposed approach of this paper is based on the principal that early intervention is the most cost-effective and efficient means of mitigating the environmental effects of development projects, particularly macro infrastructure developments. A strategic overview of the various project alternatives, taking account for stakeholder and expert input, could effectively reduce project impacts/risks at low cost to the project developers but provide significant benefit to wider communities, including communities of future stakeholders. This paper is the first exploratory step in developing a more systematic framework for evaluating strategic alternatives for major metropolitan infrastructure projects, based on key sustainability principles. The developed Strategic Project Appraisal (SPA) framework, grounded in the theory of Strategic Environmental Assessment (SEA), provides a means of practically appraising project impacts and alternatives in terms of quantified ecological limits; addresses the neglected topic of metropolitan infrastructure as a means of delivering sustainability outcomes in the urban context and more broadly, seeks to open a debate on the potential for SEA methodology to be more extensively applied to address sustainability challenges in the built environment. Practically applied and timed appropriately, the SPA framework can enable better decision-making and more efficient resource allocation ensuring low impact infrastructure development.     

How does stakeholder involvement affect environmental impact assessment?

Environmental impact assessment (EIA) processes are grounded on the assumption that producing information about environmental impacts will yield better environmental decisions. Despite the ubiquity of EIA as a policy tool, there is scant evidence of its environmental, social, or economic impacts. Focusing on Environmental Impact Statements (EIS) prepared for water and energy-related projects under the US National Environmental Policy Act, this analysis addresses two questions: (1) What is the balance of environmental impacts associated with infrastructure decisions?; and (2) How does the content of stakeholder feedback received during the review phase differ from draft EIS content, and does this correspond to any changes in the final EIS? We demonstrate the use of automated text mining approaches to identify the distribution of impacts, measure the content of public comments, and observe whether values reflected in comments are associated with a shift in emphases between the draft and final EIS. EISs are shown to convey evenly distributed focus across multiple impact areas. However, we observe no substantive change in focal emphasis between draft and final issuances. This calls into question assumptions about the role that public participation plays in bringing new information to light or changing the course of action.     

Can environmental impact assessments alone conserve freshwater fish biota? Review of the Chilean experience

Chile was one of many countries that initiated environmental impact assessments in the 1990s, and has relied on their use for species conservation and territorial planning without the use of larger-scale environmental and ecological planning. The capacity of Chile's environmental impact assessment system (SEIA) to evaluate resident freshwater fishes and the potential impacts of water projects and aquaculture activities – two categories of projects that create direct threats to freshwater fishes – are assessed. Of the 3997 such submissions to the SEIA, only 0.6% conducted any freshwater fish assessment, and only 0.1% conducted any quantitative assessment of expected impacts from the associated project. The small number of assessments was characterized by poor study design, inconsistent sampling methodology, and species misidentification. Traditional assessments failed to include freshwater fish ecology in the general assessment framework. The new strategic environmental evaluation system only underscores the need for vastly improved field sampling protocols and assessment methodologies.     

Coal mining and the resource community cycle: A longitudinal assessment of the social impacts of the Coppabella coal mine

Two social impact assessment (SIA) studies of Central Queensland's Coppabella coal mine were undertaken in 2002–2003 and 2006–2007. As ex post studies of actual change, these provide a reference point for predictive assessments of proposed resource extraction projects at other sites, while the longitudinal element added by the second study illustrates how impacts associated with one mine may vary over time due to changing economic and social conditions. It was found that the traditional coupling of local economic vitality and community development to the life cycle of resource projects—the resource community cycle—was mediated by labour recruitment and social infrastructure policies that reduced the emphasis on localised employment and investment strategies, and by the cumulative impacts of multiple mining projects within relative proximity to each other. The resource community cycle was accelerated and local communities forced to consider ways of attracting secondary investment and/or alternative industries early in the operational life of the Coppabella mine in order to secure significant economic benefits and to guard against the erosion of social capital and the ability to cope with future downturns in the mining sector.     

Indices for assessment and monitoring of large mammals within an adaptive management framework

Many development projects intended to exploit natural resourcesare occurring in fragile ecosystems, and therefore the need forsound biodiversity assessment and monitoring programs is growing.Large mammals are important components of these fragile ecosystems, yet there are few strategies that attempt to assess and monitor entire large mammal communities in relation to development projects. We propose the use of two indices applied within a framework of adaptive management. An occurrence indexassesses the composition and distribution of large mammals at a site, and an abundance index monitors the abundance of large mammals over time in relation to development. We discuss the design, applicability and effectiveness of these indices based onour experience with a natural gas development project in the Amazon forests of southeastern Peru.     

Sustainable building assessment tool for project decision makers and its development process

The primary purpose of Sustainable Building Assessment (SBA) tools is for behavioral changes in public building practice. In the Web 3.0 era, even non-experts may have the capacity to select and use Information & Communication Technology (ICT) tools to solve complicated problems in sustainable building decision making without any expert help. It is clear that the R&D of these tools which directly target project decision makers is a significant project for researchers and policy makers who are tasked with the challenge of changing individual building practice for regional sustainability. The purpose of the study is to suggest a tool and its development process for sustainable building assessment by project decision makers, especially targeting non-expert groups. This study defines an SBA tool for project decision makers based on a typology and suggests a “3-layer development process framework”. For the theoretical Background, we integrate interdisciplinary methods and principles such as cognitive problem-solving and sustainable building delivery, including long-term community benefits in a region and an information system development process. This framework is based on Boehem's spiral model for information system development processes and especially emphasizes the first cycle to develop a core set of indicators fit for the non-expert user's problem solving process. This presents an iterative and gradual process with the aim of approaching the tool type from passive tools such as checklists and guidelines, to interactive software, especially interactive DSS (Decision Support Systems) online ICT platforms. The development process is comprised of 8 stages: This includes the use of mixed-method sequential design, including interviews, workshops, the Delphi survey technique, FD-AHP weight analysis, and scenario analysis. In addition, the study presents a case study of the application of the first cycle to develop a core set of indicators and discusses its effectiveness. This study may help researchers by providing a clear and effective method to understand interdisciplinary approaches to develop appropriate tools for sustainable building practice in a regional context.     

Assessing corporate project impacts in changeable contexts: A human rights perspective

Project-level impact assessment was originally conceived as a snapshot taken in advance of project implementation, contrasting current conditions with a likely future scenario involving a variety of predicted impacts. Current best practice guidance has encouraged a shift towards longitudinal assessments from the pre-project stage through the implementation and operating phases. Experience and study show, however, that assessment of infrastructure-intensive projects rarely endures past the project's construction phase. Negative consequences for environmental, social and health outcomes have been documented. Such consequences clarify the pressing need for longitudinal assessment in each of these domains, with human rights impact assessment (HRIA) as an umbrella over, and critical augmentation of, environmental, social and health assessments. Project impacts on human rights are more closely linked to political, economic and other factors beyond immediate effects of a company's policy and action throughout the project lifecycle. Delineating these processes requires an adequate framework, with strategies for collecting longitudinal data, protocols that provide core information for impact assessment and guidance for adaptive mitigation strategies as project-related effects change over time. This article presents general principles for the design and implementation of sustained, longitudinal HRIA, based on experience assessing and responding to human rights impact in a uranium mining project in Malawi. The case study demonstrates the value of longitudinal assessment both for limiting corporate risk and improving human welfare.

Partial information and complex development decisions: Illustrations from infrastructure projects

This study assesses the theoretical and practical limitations of evaluations of infrastructure projects. Existing tools used in such evaluations typically exhibit two main limitations. Firstly, they tend to accommodate only two dimensions at once and rely on extensive use of averages for additional dimensions. Secondly, they mostly produce a narrow (project exclusive) or information that is too general, thereby precluding both broader and more detailed interpretations at once.Development decisions so informed are consequently based on partial information. Too often this has produced unsatisfactory outcomes for some stakeholders along with increased risks and heightened uncertainties. This is particularly the case for infrastructure projects.This paper proposes an alternative approach to development decision-making called ‘complex stakeholder perception mapping’ (CSPM). CSPM's evaluations inclusively involve a spectrum of insights and perception maps which offer flexibility, combined with complex perceptions of multiple stakeholders on multiple aspects of development.Applicability of CSPM is demonstrated using four perceptual dimensions in infrastructure development evaluation. Different perception combinations and individual group perceptions generate patterns which indicate aspects and groups that need attention. This approach generates rigorous interpretations of information at both the micro and macro level of the project environment, thereby supporting well-informed strategic decision making to advance project outcomes.     

Evaluating impacts of development and conservation projects using sustainability indicators: Opportunities and challenges

There has been an increased interest in using sustainability indicators for evaluating the impacts of development and conservation projects. Past and recent experiences have shown that sustainability indicators can be powerful tools for measuring the outcomes of various interventions, when used appropriately and adequately. Currently, there is a range of methods for applying sustainability indicators for project impact evaluation at the environment–development interface. At the same time, a number of challenges persist which have implication for impact evaluation processes especially in developing countries. We highlight some key and recurrent challenges, using three cases from Kenya, Indonesia and Brazil.In this study, we have conducted a comparative analysis across multiple projects from the three countries, which aimed to conserve biodiversity and improve livelihoods. The assessments of these projects were designed to evaluate their positive, negative, short-term, long term, direct and indirect impacts. We have identified a set of commonly used sustainability indicators to evaluate the projects and have discussed opportunities and challenges associated with their application. Our analysis shows that impact evaluation processes present good opportunities for applying sustainability indicators. On the other hand, we find that project proponents (e.g. managers, evaluators, donors/funders) face challenges with establishing full impacts of interventions and that these are rooted in monitoring and evaluation processes, lack of evidence-based impacts, difficulties of measuring certain outcomes and concerns over scale of a range of impacts.We outline key lessons learnt from the multiple cases and propose ways to overcome common problems. Results from our analysis demonstrate practical experiences of applying sustainability indicators in developing countries context where there are different prevailing socio-economic, cultural and environmental conditions. The knowledge derived from this study may therefore be useful to a wider range of audience who are concerned with sustainable integration of development and environmental conservation.     

Hierarchy of factors affecting the social perception of dam reservoirs

This study presents an assessment of factors that influence how people who live in the vicinity of dams view such projects. The usefulness of the principal component analysis (PCA) method for identifying variables that determine individuals' opinion about large dam projects was reviewed. The study focuses on people affected by the construction of the Mucharski Reservoir in the Polish Carpathians. The construction took over 30 years and took place at a time when Poland transitioned from a planned economy to a free market one.We used in-depth interviews (N = 96) and a set of 18 factors classified as personal, emotional and economic. Our results indicate that the variables that significantly affect social perception of dam projects by the local population include their opinion regarding the viability of the project, sense of security, personal benefits, the extent to which they have accepted the structure, respecting the local community's interests when drafting the development plans and new opportunities. The results allow for the future optimization of research tools used to comprehensively examine social perception of hydraulic structures. Using PCA allowed us to take semi-structured data from interviews and extract meaningful relationships between the various inputs, show correlations between seemingly unrelated data, as well as explain the variances within the studied population. It also shows that PCA can be a useful tool for analyzing data that is not formally structured.     

A framework for assessment and monitoring of small mammals in a lowland tropical forest

Development projects in tropical forests can impact biodiversity.Assessment and monitoring programs based on the principles of adaptive management assist managers to identify and reduce suchimpacts. The small mammal community is one important component ofa forest ecosystem that may be impacted by development projects. In 1996, a natural gas exploration project was initiated in a Peruvian rainforest. The Smithsonian Institution's Monitoring andAssessment of Biodiversity program cooperated with Shell Prospecting and Development Peru to establish an adaptive management program to protect the region's biodiversity. In thisarticle, we discuss the role of assessing and monitoring small mammals in relation to the natural gas project. We outline theconceptual issues involved in establishing an assessment andmonitoring program, including setting objectives, evaluating the results and making appropriate decisions. We also summarizethe steps taken to implement the small mammal assessment, provideresults from the assessment and discuss protocols to identifyappropriate species for monitoring.     

Environmental impact assessment system in Thailand and its comparison with those in China and Japan

This paper aims to find ways to streamline the Environmental Impact Assessment (EIA) system in Thailand to increase its effectiveness by comparative analysis with China and Japan. This study is mainly focused on review, update and comparison of EIA systems between these three countries. It is intended to clarify fundamental information of the EIA systems and characteristics of the key elements of EIA processes (screening, consideration of alternatives, prediction or evaluation of impact, and public participation). Moreover, the number of the EIA projects that have been implemented in all the provinces in Thailand are presented. The results identified the similarities and differences of the EIA processes among the three aforementioned countries. The type of EIA report used in Thailand, unlike those in China and Japan, is an Environmental and Health Impact Assessment (EHIA), which is concerned with the health and environmental impacts that could occur from the project. In addition, EIA reports in Thailand are made available to the public online and the shortcomings of the process have details of barriers resulting from the projects to help future projects with reconsideration and improvements. In this study, it is pointed out that Thai's EIA system still lacks local EIA authority which needs to be empowered by implementing a set of laws or ordinance.
