Environmental Impact Assessment of Onshore Wind Farms in the Region of Central Greece Using a Modified RIAM Method

Wind energy is one of the most basic forms of renewable energy,which shows an increasing rate of development worldwide and also at the European level.However,this rapid deployment of wind farms makes the need for an impact assessment of this type of projects on the natural and man-made environment imperative.The present paper aims to identify and assess the environmental impacts of wind farm projects in the Region of Central Greece.A modified Rapid Impact Assessment Matrix(RIAM)method is used for this purpose.The methodology includes the identification of the existing onshore wind farm projects in the study area,the appropriate modifications of the RIAM method to respond to the characteristics of the projects and the study area,the qualitative assessment of their potential impacts during construction and operational phases and the computation of the Environmental Performance Grade(EPG)of projects based on the pro-posed modified RIAM method.The results reveal that although there are some slight negative impacts on the natural environment of the study area,the examined wind farms contribute positively both to the atmosphere and to the socio-economic environment of the study.This study extends the potential for using RIAM as a tool in environmental impact assessment studies of renewable energy projects.

Environmental Impact Assessment Follow-Up of Seismic Survey Offshore Activities in Brazil

Follow-up of environmental impacts is an integral part of the Environmental Impact Assessment (EIA) process, closely related to the effectiveness of the instrument. EIA follow-up has been receiving a lot of interest from scientists and practitioners, though it is recognized as one of the weakest points of EIA systems globally. Also, EIA follow-up is influenced by the context, mainly in terms of the types of projects or activities and their related impacts on the environment. Therefore, the present paper is focused on the investigation of the follow-up stage applied to the activity of seismic survey coupled with offshore oil & gas exploitation in Brazil. Research was based on a qualitative approach that included document analysis and semi-structured interviews with analysts involved in EIA processes, and sought to generate evidence of effectiveness of the EIA follow-up as conducted by the Federal Environment Agency (Ibama) in order to situate the practice of follow-up in the broader context of international best practice principles. Based on the findings, it was concluded that, due to the peculiarities of offshore seismic survey, it is necessary to promote adaptations in the procedures for monitoring impacts in order to ensure proper alignment with the principles and conceptual foundations that guide EIA practice. Specifically, the timing of the execution of the activity imposes challenges for its integration into the “conventional” cycle that has guided the monitoring of the impacts in the EIA of projects.

Opportunities to Improve the Quality of Environmental Reports and the Effectiveness of Environmental Impact Assessment: A Case of Electric Power Transmission Systems in Brazil

A good quality Environmental Impact Statement (EIS) is key for the effectiveness of Environmental Impact Assessment (EIA) processes and consequently to the acceptability of projects subject to EIA. The international literature has contributed to the understanding of the essential aspects to be verified regarding the quality of EIS, offering a wide spectrum of good practice examples related to the content of the studies. Even so, there is a need for empirical studies that allow the identification of specific aspects related to the context of application of the EIS, which could lead to the identification of opportunities to improve both the quality of the reports and also the effectiveness of EIA. Therefore, the present paper is focused on the quality review of a number of EIS submitted to the Brazilian Federal Environmental Agency (Ibama) to instruct the assessment of electric power transmission systems. Based on the application of the EIS quality review package as proposed by Lee and Colley (1992), the outcomes reveal opportunities for improving the scope of EIA, analysis of alternatives, prediction of magnitude and the assessment of impact significance. Finally, the development and/or adaptation of a similar tool for the systematic review of the quality of EIA reports is recommended.

Assessing the Environmental Impact of Extensive Beef Production in Grazing Lands of Argentina

Because of environmental constraints,beef cattle was for more than a century the only viable farming option in the extensive semiarid and subhumid lands of Argentina and the main source of nutrients for humans as well.However,a growing concern and criticism have risen today about its possible negative impact on the climate and the environment.These worries tend to affect current public opinions,national policies,and international trade.Based on 40 beef cattle farms scattered across different semiarid and subhumid regions of Argentina,here we evaluated the impact of extensive cattle production on carbon,water,and nutrient pollution.Life-Cycle Assessment(LCA)and Land-Based Assessment(LBA)were the two approaches we used here to compare the environmental impact of beef production.While the environmental footprint(EF)resulting from LCA expresses the impact per unit of food,the environmental balance(EB),derived from LBA,aims at quantifying the impact per unit of land.As such,the EB considers both negative and positive impacts on the farm as an integrated system.Following standardized procedures,we evaluated EF and EB up to the farm gate,leaving aside delocalized post-farm impacts such as those of processing,packaging,and transportation that occur beyond the farm gate.In agreement with previous evidence,our results show that the EF tends to decrease as per-head production increases.Correlation coefficients and statistical significance were the following for carbon(R=−0.574;p<0.01),water(R=−0.561;p<0.01),and N(R=−0.704;p<0.01)and Phosphorus(P)pollution(R=−0.802;p<0.01)footprints.On the contrary,the EB seems to be highly sensitive,and as per-hectare beef production increases.Correlations were the following for carbon emissions(CE:R=0.955;p<0.01),water consumption(WC:R=0.822;p<0.01),nitrogen excretion(NE:R=0.948;p<0.01)and phosphorus excretion(PE:R=0.945;p<0.01).What our results suggest is that the notion of EF is useful to evaluate the environmental impact in intensive beef production systems,and the EB is suitable to assess the impact of the extensive ones.In practice,both approaches provide different perspectives on the environmental-impact problem and they should be complementary used.We concluded that the methodological rigidity of EF does not allow proper discrimination among farms in the extensive systems.On the contrary,the EB approach tended to be highly sensitive to detecting differences between individual farms and farmers,thus allowing the identification of successful options for extensive beef production in terms of public image,policy-making,and commercial opportunities.

Importance of Public Engagement in Environmental Impact Assessments (EIAs) and the Benefits of Stakeholder Involvement in Project Design, Environmental Soundness, and Social Acceptability

The paper discusses the importance of public engagement in environmental impact assessments (EIAs) and the benefits of stakeholder involvement in project design, environmental soundness, and social acceptability. It highlights the negative repercussions of mining activities in Ghana, including health consequences such as skin conditions, fever, coughs, diarrhea, malaria, and catarrh, as well as HIV/AIDS infection among those engaged in or connected to prostitution in mining towns. The environmental effects of mining in Ghana include noise pollution from heavy trucks, contamination of water bodies with chemicals from mineral refining, pollution of agricultural soils leading to reduced food productivity, and wildlife depletion from deforestation. The activities of small-scale miners, particularly those engaged in illicit mining, have a negative impact on water quality and increase the cost of water treatment for public consumption. Mining operations have detrimental effects on the social, cultural, and natural ecosystems in Ghana, affecting the quality of life of local communities. The study takes into consideration the impact of mining activities on the environment and natural resources in Ghana, as these are vital to the livelihoods of Ghanaian communities. Stakeholders in Tarkwa claim that mining operations have distorted the natural path of the river, leading to excessive pollution and making the water unfit for consumption. Ghana’s economy depends heavily on mining, which also contributes significantly to GDP and generates jobs for a large number of people. But mining also has a lot of negative repercussions, the effects of mining extend beyond the mineralized zone initially explored, highlighting the need to consider the environmental impact at every phase of the mining process.

A Model for Environmental Impact Assessment of Land Reclamation

Land reclamation is a complex marine environmental engineering and has a huge impact on social, economic, and physical environment. Reclamation environmental impact assessment （REIA） is also a complicated project, including the assessment of social economic background, ocean engineering, coastal geomorphology, sediment transportation, marine hydrodynamics and marine ecosystem and so on. Nowadays, a large number of land reclaimed projects have been carried out or in the process of construction along the coastal zone, thus, it is necessary to build up a fnmlework on REIA to evaluate and quantify the environmental changes, to contribute to reclamation program, to reduce marine environmental disasters, and to sustain development of coastal zone. This article focuses on the research of REIA framework theory and puts forward a REIA model on land reclaimed evaluation, at the same time, applies this assessment system in Shenzhen City, which is a highly developed coastal city with an expectation of land reclamation. By use of the Remote Sensing （RS） and Geographic Information System （GIS） techniques, along with the topographic map and in situ survey in recla- mation area, it concludes that the area of 2680 hectares in total has been reclaimed in Shenzhen city by the end of the year 2000. Thus, reclamation is usually applied to meet the needs for infrastructure, such as harbors, industries and highways in Shenzhen City. However, some serious negative impacts have been created to the coastal environment shown clearly in the following aspects. Firstly, it caused the dramatic changes of tidal flat and channels along the western coast, made this area more unstable, which is threatening the function of the harbor in this area. Secondly, Tidal prism has decreased rapidly. During the 20 years of reclamation, the tidal prism has been reduced by 20% - 30% along the western coast in the Lingdingyang Estuary, and 15.6% in the Shenzhen Bay. As a result, the velocity of the tidal current has also declined, and the direction of the tidal current has changed, which is harmfid to the dilution and diffusion process of the contaminants. Thirdly, it has threatened the eco-environment finally. More than 147 hectares of mangrove area along the coast of Shenzhen Bay, accounting for 48.8% of the total mangrove reserve area in this region, has been reclaimed only during the short period from 1988 to 2000. Thus, the biodiversity is decreasing, and more and more plants and animals are disappearing. Based on the above analyses of the environmental impacts, strategies and suggestions for the future reclamation in this area have been put forward in order to support the sustainable development of the coastal zone.

Life cycle environmental impact assessment of biochar-based bioenergy production and utilization in Northwestern Ontario,Canada

Biochar-based bioenergy production and sub- sequent land application of biochar can reduce greenhouse gas emissions by fixing atmospheric carbon into the soil for a long period of time. A thorough life cycle assessment of biochar-based bioenergy production and biochar land application in Northwestern Ontario is conducted using SimaPro Ver. 8.1. The results of energy consumption and potential environmental impact of biochar-based bioenergy production system are compared with those of conventional coal-based system. Results show that biocbar land application consumes 4847.61 MJ per tonne dry feedstock more energy than conventional system, but reduces the GHG emissions by 68.19 kg CO2e per tonne of dry feed- stock in its life cycle. Biochar land application improves ecosystem quality by 18 %, reduces climate change by 15 %, and resource use by 13 % but may adversely impact on human health by increasing disability adjusted life years by 1.7 % if biomass availability is low to medium. Replacing fossil fuel with woody biomass has a positiveimpact on the environment, as one tonne of dry biomass feedstock when converted to biochar reduces up to 38 kg CO2e with biochar land application despite using more energy. These results will help understand a comprehensive picture of the new interventions in forestry businesses, which are promoting biochar-based bioenergy production.

Environmental Impact Assessment of HF Emission in South of Iran by Gaussian Atmospheric Dispersion Model

Iran, as a developing country has been facing rapid growth in the energy demanding sectors and needs to achieve essential elements of sustainable development. Environmental impact assessment of factories which emit hazardous gases such as HF would promise a fruitful future to achieve sustainable development. This study reveals an environmental impact assessment that has been carried out for an Aluminum Complex to be located in south of Iran. Application of Gaussian model showed that the highest concentration at the center of HF plume is 2.65 gr/sec; whereas the average wind speed is 9.1 Knots, the emission rate is 1.24 gr/sec, downwind distance 400 m and the atmospheric stability is in A class. For unstable atmospheric conditions the amount of HF emission comes to be one forth of Iran＇s national standard. It is also suggested that real-time monitoring of the pollutant particles and emissions, together with adapting proper mitigation plans and management skills, will lead to maximum efficiency with the least harmful environmental impacts.

Planning Environmental Impact Assessment Orienting Sustainable Development: Opportunities and Challenges

Strategic Environmental Assessment is a frontier subject in the field of Environmental Impact Assessment. In the past two decades, especially in recent years, much more importance has been attached to Strategic Environmental Assessment. The Environmental Impact Assessment Law of the P.R. China which was promulgated provides a great opportunity for the development of Planning Environmental Impact Assessment and brings great challenges for the development of traditional Project Environmental Impact Assessment and Planning Environmental Impact Assessment at the same time. In order to promote the implementation of "The EIA Law", the inherent limitations of Project Environmental Impact Assessment must be identified sufficiently and the theory research and practice of Planning Environmental Impact Assessment should be strengthened as well. Measures should be taken currently to enforce the operation system. The authors wish to offer a few references to the progress and implementation of Planning Environmental Impact Assessment in China.

Reformed Environmental Impact Assessment in China: An Evaluation of Its Effectiveness

Since 2015, a “reform storm” of Environmental Impact Assessment (EIA) opened up in China. This study tries to answer the question of whether these reforms improve the effectiveness of EIA. First, we elaborate on the reforms along with three well-acknowledged components, including EIA legislation, administration, and process. Then, evaluate the reformed EIA system against revised Ahmad and Wood’s criteria. The results demonstrate that the revised laws and regulations are more stringent than the old versions. The EIA process is simplified, and its coordination with the pollutant discharge permit system is promoted. The interim and post-event supervision is currently more robust and the penalties are more severe than before. However, the hierarchical position of the Environmental Protection Law is not high enough and the coordination of different government departments is still challenging. In summary, despite the problems occurring at the initial phase of reforms, the effectiveness of the EIA system has largely been improved.

Development of a Geographic Information Systems Baseline Spatial Geodatabase Template for Evaluating Potential and Predicted Environmental Impacts for Sustainable Environmental Impact Assessment of Mining in Sierra Leone

Baseline Environmental Impact Assessment (EIA) of mining projects in Sierra Leone creates a challenging environment for data collection and impact prediction. Application of geographic information systems provides suitable spatial analysis data collection methods to reduce the challenges created by mining environments. This research develops a baseline spatial geodatabase template for evaluating potential and predicted environmental impacts assessment of mining projects in Sierra Leone. It is observed that spatial analysis of impacts of mining projects on the environmental attributes, especially air, noise, water, land, and socio-economy in mining areas is largely unexplored in Sierra Leone. The literature review revealed that no complete GIS spatial data geodatabase collection template appears to have been developed to date to provide an integrated sustainable spatial analysis and modelling tool for EIA and environmental management of mining in Sierra Leone. Therefore developing a Geographic Information Systems baseline geodatabase template for the evaluation of potential and predicted environmental impact for sustainable environmental impact assessment of mining in Sierra Leone will: 1) provide support to the data acquisition process of environmental impact assessment, 2) offer a concept for developing analysis methods for environmental management of mining, 3) minimize the undesired environmental impacts of mining, and 4) give an optimal proposal for data collection and analysis of mining industry in attaining sustainable development in Sierra Leone. Due to the limited available data, a conceptual GIS database template has been developed rather than a database case study of a mining site. No site investigation and data collection were undertaken. The geospatial database template was designed using ArcCatalog, ArcGIS 10.7.1. software, through the following steps: exploration of the general data requirement of environmental impact assessment studies of mining, the definition of the general baseline datasets requirement of environmental impact assessment in mining, structuring of the environmental impact assessment baseline spatial geodatabase, creating the geographic geodatabase dictionary, selecting, matching geographic data with geodatabase structure, designing the feature class and attributes, creating the baseline GIS geodatabase template. The GIS spatial geodatabase template has several advantages for environmental impact assessment of mining including avoiding data redundancy, integrating data into a single database, creating uniformity in data collection, easy to find and track data, integrated spatial and non-spatial data, and reducing the volume of data.
