Most development activities have individually minor impact, but collectively over time their impact on the environment is more substantial. The available environmental circumstances in different locations show the important position of cumulative effects (CEs) in environmental studies. Many sources notified the complexity of cumulative effects assessment (CEA) in practice and identification of CEs in assessments. Maybe it is because the essence of impact assessments have to focus on future consequences, and this situation is complex substantive. Also, a lack of knowledge with respect to how to include CEs and lack of clear regulations concerning how this should be done are the most complex criteria of CEA which have been mentioned by CEA practitioners. Most guides and regulations are considered in the performance of CEA during environmental impact assessment (EIA) of projects. Also, there is an important consideration regarding performance of CEA in strategic environmental assessments (SEAs) process, and some reasons present it. In the section of methods and tools used for CEA, risk assessment approaches and modeling are the most used innovative methodologies for the improvement of CEA in recent times. Generally, improvement in performance and knowledge of CEA is noticeable in recent years.

Annotation:

Environmental impact assessments for offshore oil and gas activities have historically focused on the specific impacts from an individual, and independent, activity. However, as Australia’s environmental assessment process continuously improves, it has become increasingly evident that cumulative impacts from previous, concurrent, or future activities need to be taken further into consideration. Cumulative impacts occur when multiple activities are conducted simultaneously, or consecutively, within the same region resulting in a greater level of potential impact to the environment than what would occur from the individual activity alone. Development of a standardised Cumulative Impact Assessment (CIA) methodology has been a well argued, and inherently difficult task, leading to current processes considered inadequate globally. With Australia moving in the direction of increasing, and diversifying its offshore energy activities, conducting adequate CIAs within the marine environment has become an increasingly important topic. We explore the challenges others have faced to develop a suitable methodology and shed light on the role CIAs will play during the energy transition phase in Australia. We conclude by outlining the fundamental aspects that require consideration to comprehensively assess cumulative impacts.

Cumulative risks and impacts have taken on different meanings in different regulatory and programmatic contexts at federal and state government levels. Traditional risk assessment methodologies, with considerable limitations, can provide a framework for the evaluation of cumulative risks from chemicals. Under an environmental justice program in California, cumulative impacts are defined to include exposures, public health effects, or environmental effects in a geographic area from the emission or discharge of environmental pollution from all sources, through all media. Furthermore, the evaluation of these effects should take into account sensitive populations and socioeconomic factors where possible and to the extent data are available. Key aspects to this potential approach include the consideration of exposures (versus risk), socioeconomic factors, the geographic or community-level assessment scale, and the inclusion of not only health effects but also environmental effects as contributors to impact. Assessments of this type extend the boundaries of the types of information that toxicologists generally provide for risk management decisions.

In order to alleviate climate change consequences, UK governments are pioneering offshore energy developments with increasing commitment. The North Sea is a dynamic ecosystem with strong bottom-up/top-down natural and anthropogenic drivers facing rapid climate change impacts. Therefore, to ensure the compatibility of such large-scale developments with nature conservation obligations, cumulative effects need to be evaluated through cumulative impact assessments (CIA). However, by excluding climate change impacts, CIA lacks spatio-temporal appropriate baselines linking ecosystem components (e.g. physical indicators) to population dynamics which leads to uncertain predictions at populations levels. This study presents an overview of a framework for CIA using a holistic and pragmatic ecosystem approach based on spatio-temporal Bayesian network in order to identify pressure pathways, keystone components, ecosystem connectivity and resilience as well as population-level changes. We will also present potential fine-scale environmental monitoring solutions and data sources generated at MRED (Marine Renewable Energy Developments) site levels. Finally, we will discuss the usefulness of the two components that make up this framework: a database and an application of standardised shared tools that will pave the way to more transparent and multi-disciplinary collaborations. This framework will provide a multi-dimensional decision-making toolkit that would also lead towards more efficient SEAs (Strategic Environmental Assessment) as well as providing the ability to embed the CIAs of projects into regional and multinational schemes.

Cumulative effects assessment (CEA) is a development of environmental impact assessment which attempts to take into account the wider picture of what impacts may affect the environment as a result of either multiple or linear projects, or development plans. CEA is seen as a further valuable tool in promoting sustainable development. The broader canvas upon which the assessment is made leads to a suite of issues such as complexity in methods and assessment of significance, the desirability of co-operation between developers and other parties, new ways of addressing mitigation and monitoring. After outlining the legislative position and the process of CEA, this paper looks at three cases studies in the UK where cumulative assessment has been carried out - the cases concern wind farms, major infrastructure and off-shore developments.

The outcomes of environmental impact assessment (EIA) influence millions of hectares of land and can be a contentious process. A vital aspect of an EIA process is consideration of the accumulation of impacts from multiple activities and stressors through a cumulative effects assessment (CEA). An opportunity exists to improve the rigor and utility of CEA and EIA by incorporating core scientific principles of landscape ecology into EIA. With examples from a Canadian context, we explore realistic hypothetical situations demonstrating how integration of core scientific principles could impact EIA outcomes. First, we demonstrate how changing the spatial extent of EIA boundaries can misrepresent cumulative impacts via the exclusion or inclusion of surrounding natural resource development projects. Second, we use network analysis to show how even a seemingly small, localized development project can disrupt regional habitat connectivity. Lastly, we explore the benefits of using long-term historical remote sensing products. Because these approaches are straightforward to implement using publicly available data, they provide sensible opportunities to improve EIA and enhance the monitoring of natural resource development activities in Canada and elsewhere.

The coal seam gas (CSG) industry in Queensland has expanded rapidly in the Surat and Bowen basins within this decade. Depressurisation for CSG production has the potential to affect overlying and underlying aquifers. This leads to wide-ranging stakeholder concerns around the groundwater impacts, particularly cumulative effects, because the coal seams are part of the Great Artesian Basin. Relatively early in the development cycle, Queensland set a framework whereby an area of intensive petroleum and gas development is proactively declared to be a cumulative management area. For such areas, the independent Office of Groundwater Impact Assessment (OGIA) undertakes cumulative impact assessment and prepares management arrangements that are reported through the underground water impact report. OGIA’s assessment through its iterative reporting–monitoring–modelling cycle has been providing the basis for managing and monitoring groundwater impacts on the ground and providing clarity in tenure holders’ responsibilities. OGIA has also built extensive knowledge of the groundwater systems and developed innovative modelling techniques over the years that have wider application elsewhere. This paper shares OGIA’s journey in the process.

This paper reflects on the state of cumulative effects research in Canada and future directions and challenges. The assessment and management of cumulative effects has been an enduring theme in the impact assessment literature, and scholars have consistently identified the challenges to assessing and managing cumulative effects under regulatory, project-based impact assessment. Current research on cumulative effects is focused largely on the development of frameworks and methodologies to advance cumulative effects assessment and management from individual projects to broader regional scales, and on developing the science and tools for assessing and monitoring cumulative effects. Ensuring that scholarly research continues to shape cumulative effects practice in the future requires that scholars not only attempt to improve practice under current existing regulatory processes, but also push the boundaries to ensure that decision processes also evolve so as to be accommodating of new and innovative approaches to cumulative effects at regional scales. This requires interdisciplinary approaches and sustained research funding, both of which present practical challenges to scholars, and research programmes that are developed in collaboration with industry, governments and communities.

Abstract: Life cycle assessment (LCA) is a tool to evaluate environmental impacts based on products of a process. This research is a case study of wastewater treatment facilities of ERTC (Environmental Resources Training Center), SIUE University, based on available data for two semi-annual sludge quantities (year 2015) from sludge management report. The aim of this study is to compare set of possibilities for a wastewater treatment facility at ERTC. The simulation has been done through SimaPro model. Electricity and methane were considered and the cumulative weight of their impacts has been investigated. Total solids for two semi-annual sludge has been fed to the model in kilogram and different production (electricity and methane) configuration were investigated. The most plausible configuration based on the cumulative environmental impact proposed as best practical solution.

Abstract Accurate assessment of the overall impacts of anthropogenic activities on mobile, migratory species requires cumulative year-round impact assessments covering their entire annual cycle. This study considers the type of information needed and the assessment tools required to implement such assessments. The developed concept is demonstrated by modelling year-round collisions of Black-legged Kittiwakes (Rissa tridactyla) breeding on the German North Sea island of Helgoland with constructed and planned offshore wind farms across the species distributional range, in order to assess the endangerment status of the local population.

This study analyzed the environmental impacts due to lead production in China, which is the largest producer and consumer of lead in the world, by the method of life cycle assessment (LCA). Based on the Chinese refined lead smelting process, a process-based life cycle assessment model was established to assess the environmental load of lead production system which includes the processes of mining, beneficiation, smelting, electrorefining and transportation. The result shows that the cumulative consumption of electricity and the cumulative emission of green house gases for the production of 1t of refined lead are 1111.93kWh and 2.06E+03kg CO2 eq, respectively. Smelting process is the largest contributor to the environmental impact load, accounting for 51.16% of the total environmental impact. The environmental category of human toxicity potential(HTP), accounting for 35.26% of the total environmental impact, is the largest contributor between different environmental categories to the total environmental impact, followed by metal depletion potential(MDP) and fossil depletion potential(FDP), accounting for 27.94% and 11.80% of the total environmental impact, respectively. Improving the resource efficiencies of the processes of smelting and beneficiation, and using cleaner energy to generate electricity are the key approaches to reduce the overall environmental impact of lead production in China.

Cumulative effects assessments have been defined as environmental assessments done well. However, socioeconomic studies within the EIA process seldom adequately address cumulative effects. One of the reasons for this is that the socioeconomic tools used in the EIA process have not been evaluated and, where necessary, updated to address cumulative effects. This article evaluates current and potential tools, from a variety of paradigms, including economic, industrial ecology and systems theory. An unexpected result was that traditional economic appraisal techniques such as CBA performed quite well against identified criteria. In addition, a number of other newer techniques were also found to be suitable. The article concludes with recommendations on how to practically address cumulative effects in socioeconomic studies.

The Independent Expert Scientific Committee on Coal Seam Gas and Large Coal Mining Development (IESC) is a statutory committee that provides scientific advice to Australian governments on the impacts that each coal seam gas (CSG) and large coal mining development may have on water resources. In this context, the IESC consider all aspects of a water resource, including water, organisms and ecosystems that contribute to or rely on them. The Office of Groundwater Impact Assessment (OGIA) is an independent statutory entity responsible for undertaking cumulative impact assessments from CSG and other petroleum production in Queensland, including the Surat Cumulative Management Area (CMA). OGIA also establishes impact management arrangements and identifies responsible tenure holders to implement specific aspects of those arrangements. Neither the IESC nor OGIA are regulators. Due to their respective functions both entities have different roles and interaction with CSG development in the Surat CMA. The IESC and OGIA engage regularly to ensure a shared understanding of knowledge, research and management. This paper provides an overview of key synergies between the roles and functions of the IESC and OGIA and considerations for proponents when using OGIA assessment in their environmental assessments that are referred to IESC for advice.

ObjectiveTo examine the effect of concussion history and cumulative exposure to collision sports on baseline serum biomarker concentrations, as well as associations between biomarker concentrations and clinical assessments.MethodsIn this observational cohort study, β-amyloid peptide 42 (Aβ42), total tau, S100 calcium binding protein B (S100B), ubiquitin carboxy-terminal hydrolyzing enzyme L1 (UCH-L1), glial fibrillary acidic protein, microtubule associated protein 2, and 2′,3′-cyclic-nucleotide 3′-phosphodiesterase serum concentrations were measured in 415 (61% male, 40% white, aged 19.0 ± 1.2 years) nonconcussed collegiate athletes without recent exposure to head impacts. Regression analyses were used to evaluate the relationship between self-reported history of concussion(s), cumulative years playing collision sports, clinical assessments, and baseline biomarker concentrations. Football-specific analyses were performed using a modified Cumulative Head Impact Index. Clinical assessments included symptom, cognitive, balance, and oculomotor tests.ResultsAthletes with a greater number of concussions had a higher baseline Aβ42 concentration only (ρ = 0.140, p = 0.005, small effect size). No biomarker concentrations correlated with cumulative exposure to collision sports. Race status fully mediated the correlations of S100B, UCH-L1, and Aβ42 with cognitive scores. Football exposure, specifically, was not associated with serum biomarker concentrations or clinical assessment scores based on the modified Cumulative Head Impact Index.ConclusionConcussion-related serum biomarkers showed no consistent association with concussion history, cumulative exposure to collision sports, or clinical assessments in a sample of healthy collegiate athletes. Serum Aβ42 concentrations could increase following multiple previous concussions. Considering race status is essential when investigating links between biomarkers and cognition. The biomarkers studied may not detect residual effects of concussion or repetitive head impact exposure in otherwise asymptomatic collegiate athletes without recent exposure to head impacts. Much more research is needed for identifying reliable and valid blood biomarkers of brain trauma history.

Combined with the characteristics of the high-speed railway regional environment system, the paper establishes a cumulative environment impact assessment model with the system dynamics in the high-speed railway regional, which is divided into three subsystems: economic, environment and pollution subsystems. Each subsystem is refined into a number of state indexes. The feedback relationships is set up between each state index and various subsystems, based on the Matrix method, Delphi, Analytic Hierarchy Process and environmental carrying capacity to establish comprehensive evaluation model of the cumulative environment impact assessment in the high-speed railway region. Finally the Chang-Yi high-speed railway is taken as an example.This paper is of the important theory and practice significance to promote the cumulative impact assessment level and social environment benefit of the high-speed railway regions.

Despite the central role of valued ecosystem component (VEC) selection to project impact assessment (IA) and cumulative effects assessment (CEA), little is known about what influences it. To potentially improve the efficacy of CEA, a look into the "black box" of VEC selection is warranted. An investigation of eleven road construction project IAs in Canada completed between 1995 and 2011 via document analysis and interviews with project informants reveals a heavy reliance on residual effects analysis for CEA VEC selection, such that project VEC list are often exactly or nearly the same as CEA VEC lists. The process of VEC selection is highly subjective, lacking in scientific inputs, and not as sensitive to cumulative effects issues as it perhaps should be given the nature of road projects. The study concludes that a "residual effects analysis—plus" approach to CEA VEC selection is desirable, along with explicit, possibly sector-specific, guidance.

AIMS: Cumulative assessment has been used as a tool to steer students’ study behavior, since it increases students’ self-study time while spreading their study time more evenly throughout the span of the course. However, little is known about the impact of cumulative assessment on students’ knowledge growth. Therefore, our study compared the growth of knowledge of students who attended a course with cumulative assessment with those with end-of-course assessment. We hypothesized that students in the cumulative assessment condition would have a higher increase in knowledge compared to students in the end-of-course assessment condition.METHODS: This is a follow-up study of a previous randomized experiment that compared students’ performance between students who attended a course with cumulative assessment with those with end-of-course assessment. We gathered data of the first four subsequent Dutch interuniversity progress test after the experiment from 62 students. Of those, 37 students were in the end-of-course assessment condition and 25 were in the cumulative assessment condition. The questions were classified as part of the teaching block or not. To analyze students’ knowledge growth, we conducted a General Linear Model.RESULTS: Our results demonstrated that there was a significant increase in students’ knowledge of the four subsequent progress tests. Additionally, our general linear model showed no difference between both groups, indicating that cumulative assessment and end-of-course assessment produced similar outcomes when comparing students’ knowledge growth.CONCLUSIONS: So far, little evidence has supported the use of cumulative assessment as a tool for increasing students’ knowledge growth. The lack of finding a positive effect of cumulative assessment on knowledge retention may be explained by the repetitive character of our (spiral) curriculum.

The environmental impact assessment is a process required in many countries. It highlights future activities with a significant impact on the environment. Water, as an environmental factor, needs adequate methods for quantifying cumulative impact of hydrotechnical works. In most cases, for new developments, baseline data is collected before the beginning of the construction, but for waterworks already in place, a different approach is needed. In line with the EU Water Framework Directive (Directive 2000/60/EC), the overall purpose of the research is to develop an approach for the hydromorphological cumulative impact assessment integrating different spatial scales for existing water intakes with transversal barriers on mountain rivers in Romania. Being a research study developed for a specific issue—post-construction impact assessment, some innovative actions were required. Lack of information in the pre-construction phase was an important constraint. Customizing formulas of certain indicators established within the Romanian method for hydromorphological status assessment of rivers proved to be a practical solution to show both local and waterbody hydromorphological impact. Upscaling the impact from the local scale to the river sector and the waterbody allows awareness of the spatial extent of the impact and understanding of the importance of the thresholds of significant impact for a broader audience. In order to better highlight the approach, this paper shows practical examples. The whole chain of the drivers–pressures–state–impacts–responses (DPSIR) framework is applied in the case of two river water bodies with hydropower generation facilities in place. In addition, some recommendations for actions are provided.

This paper focuses on evaluation of the heat exchange process based on cumulative exergy analysis method. The case study chosen is the countercurrent heat exchange process that is widely used in the industrial processes. The optimal design is achieved by minimizing the annual total cumulative exergy consumption of the cold stream. The natural resource-oriented mathematical models are established in details. Obviously, the results from cumulative exergy optimization are imposed by the present state of the technology compared with the ones from thermoeconomics

As recently as two years ago, there were numerous proposals to develop coal seam gas projects across eastern Australia. Today the picture is very different. While significant coal seam gas development has occurred in the Surat Basin, Metgasco has surrendered their licences and AGL have indicated that they will not proceed in Gloucester. The only coal seam gas development that is still proceeding in NSW is Santos’s proposal in the Liverpool Plains (Namoi). However, recent developments in Australian Government policy to increase gas supply on the eastern seaboard means that the results of these assessments will inform future decisions. Research carried out as part of the Bioregional Assessment Programme (BAP) has shown some surprising results in the Richmond River (Clarence-Moreton bioregion) regarding the potential impacts of coal seam gas development on the water resources and water-dependent assets of that region. This study will show how we developed a groundwater and surface water cumulative impact model in the Clarence-Moreton bioregion, and present the key findings from that modelling. Similar cumulative impact assessments are currently underway in the Maranoa-Balonne-Condamine, Gloucester, Hunter, Galilee, and Namoi regions and we expect these to be published by late 2017. As part of a core tenet of transparency in the BAP, the data collected and models developed as part of these assessments will be freely available for Industry proponents, State regulators and other interested parties to access and utilise. The Surat cumulative management area in south-eastern Queensland has provided a structure for developing coal seam gas resources while protecting water resources via a cumulative approach to management. We propose that the models we have developed would provide the basis of a similar structure to assess and manage cumulative impacts in regions across Australia that may see coal seam gas or other forms of unconventional gas development.

The damage of structure and technical performance of vehicle were affected by the impact at landing process of airborne. For researching the cumulative damage of airborne vehicle under impact, airdrop tests would consume lots of manpower and material resources. So numerical simulation offered one of available means for this problem. Based on the finite element model of vehicle and airbags, the calculation and assessment method for cumulative damage under landing impact time after time was proposed. The creditability of finite element model was validated by airborne test under typical condition. Associated with Lemaitre damage model and the damage evolution law of the material, the cumulative damage of the structure of vehicle was calculated. The results would provide theoretical reference and technical guidance for the design and maintenance of the airborne vehicle.

Context: Managing a concussion injury should involve the incorporation of a multifaceted approach, including a vision assessment. The frontoparietal circuits and subcortical nuclei are susceptible to trauma from a concussion injury, leading to dysfunction of the vestibulo-ocular system. Research investigating the effect of cumulative subconcussive impacts on neurological function is still in its infancy, but repetitive head impacts may result in vestibular system dysfunction. This dysfunction could create visual deficits, predisposing the individual to further head trauma. Objective: The purpose of this study was to investigate the cumulative effect of subconcussive impacts on minimum perception time, static visual acuity, gaze stability, and dynamic visual acuity scores. Design: Prospective cohort. Setting: Division I university. Patients: Thirty-three Division I men’s lacrosse players (age = 19.52 [1.20] y). Intervention: Competitive lacrosse season. Main Outcome Measures: At the beginning and end of the season, the players completed a vestibulo-ocular reflex assessment, using the InVision™ system by Neurocom® to assess perception, static acuity, gaze stability, and dynamic visual acuity. Score differentials were correlated with the head impact exposure data collected via instrumented helmets. Results: A significant correlation was found between change in perception scores and total number of head impacts (r = .54), and between changes in dynamic visual acuity loss scores on the rightside and maximum rotational acceleration (r = .36). No statistical differences were found between preseason and postseason vestibulo-ocular reflex variables. Conclusions: Cumulative subconcussive impacts may negatively affect vestibulo-ocular reflex scores, resulting in decreased visual performance. This decrease in vestibulo-ocular function may place the athlete at risk of sustaining additional head impacts or other injuries.

The need to advance the assessment of cumulative environmental effects beyond the individual project, to the broader regional scale and strategic tier, is well argued. However, regional strategic environmental assessment (SEA) frameworks that facilitate cumulative effects assessment (CEA) at this scale and tier have been slow to evolve. The need for such frameworks is now at the forefront of Canadian environmental assessment. This paper examines current and recent attempts at regional, and strategic-type assessment frameworks to integrate and assess cumulative environmental effects. Based on lessons from practice and interviews with practitioners and administrators, we observe that assessing cumulative effects in a regional SEA context is most effective when there is a shared regional vision about the future state of environment and development; the development of regional environmental targets, thresholds and indicators takes precedent over cumulative impact prediction; strategies can be translated into operational terms and mandates; the assessment is sensitive to key decision windows; and CEA is recognised to be more than simply the "adding up" of environmental effects. Regional SEA is the most appropriate framework within which to address cumulative effects, if the primary goal is to influence the nature and pace of conservation and development in support of regional sustainability.

Abstract Wind, wave and tidal energy are widely regarded as being the ‘good guys’ in energy production for their carbon neutral qualities. However, lurking in the shadow of this good reputation is the uncertainty about the impacts that this new technology will have on the marine environment. It could cause a potential conflict between carbon-neutral energy production and the protection of habitats, and the prevention of biodiversity loss. This article presents empirical data collected from three case studies in England and Scotland. This research indicates that the disjointed nature of the consenting processes for offshore renewables does not encourage full assessment of the cumulative impacts of offshore renewable developments as required by European Union environmental impact assessment legislation. The article identifies elements of the consenting processes, which fail to provide a full assessment of cumulative and in-combination impacts, and recommends changes to these processes in England and Scotland.
