A review on methodologies adopted during environmental impact assessment of development projects
Environment Impact Assessment (EIA) is one of the proven anticipatory and legislative tool used to predict the environmental consequences of any development project. It is a decision making tool used to anticipate and quantify the positive and negative impact of a proposed development project on environment consisting of a social, economic and biophysical aspects. The purpose of the assessment to assist decision makers in considering the environmental impacts of proposed project when deciding whether to proceed with a project. Numerous EIA methodologies have been developed such as Interaction Matrices, Network, Checklist, Life Cycle Assessment (LCA), Rapid Impact Assessment Matrix (RIAM) and Data Envelopment Analysis (DEA). Although, there are number of studies on EIA methodologies to identify their strength and weakness, the adequacy of impact assessment methodologies was evaluated in terms of specific criteria like impact identification, impact communication and impact interpretation. A review on these EIA methodologies and their adoption has been presented in the current study. The aim of this review paper is to find out that, which method we can use to assess the environmental assessment of highway road expansion in mountainous regions.
A Review Article on"Environmental Impact Assessment (Eia)
In recent years, there has been a remarkable growth of interest in environmental issues, sustainability and the better management of development in harmony with the environment. Associated with this growth of interest has been the introduction of new legislation, emanating from national and international agencies (e.g. the European Commission) that seek to influence the relationship between development and environment. Environmental impact assessment (EIA) is an important example. EIA means identify, predict and evaluate the environmental effects of proposed actions. EIA is a tool of decision-making development. The three core value of EIA study that has been identifying till date is integrity, utility and sustainability. EIA is a tool for measuring environmental impacts of a upcoming projects or activity covering physical and social factors and providing measure to minimize their impacts. In real sense it is a tool to evaluate the impact of business activity, profitable planning or action leading to bio-geophysical environment and on the health and well being of human beings and interpreting and making public aware about the same. That is to say, EIA focuses on various complications, hardships faced by environment in terms of curtailment of natural resources or human health proned to the upcoming project. It also examines implications of a project that might harm people, their homeland or their livelihood or other nearby developments. After predicting the problems, an

ABSTRACT Environmental Impact Assessment (EIA) is a decision making process to analyze environmental impacts.This paper is related to EIA of proposed six kilometer road from Kalishuri to Surjomoni Union at Bauphal, Patuakhali that conducting by Local Government and Engineering Department (LGED). The proposed area is so far behind to good communication facilities within the different parts of this region due to absence of road connecting to other area. The significance of the proposed road involves directly to the people of that region in developing their social, economic and environmental condition.The aims of the study are to find out the potential environmental impacts, mitigation measures and to compute the environmental impact value (EIV) of the project.The key findings of this study include environmental positive and negative impacts mainly decreasing plant biodiversity, hydrology and agricultural lands. The study reveals that the EIV is -1 (negative one) in regarding to three environmental factors named ecological, physico-chemical and human interests. The mitigating options of various impacts on the project are environmental friendly technology, conservation of road side plantation, agricultural lands etc.The EIA helps to complete an environment friendly project by providing sound management on environmental impacts and means of preventing or reducing those impacts. Keywords: Environmental Impact Assessment (EIA), Environmental Impacts, Mitigation Measures, Environmental Impact Value (EIV), Road Construction.
Key Elements Analysis of Projects’ Environmental Impact Assessment
DAAAM Proceedings, 2016
In all areas of human activity, the greatest achievements have been achieved by projects. Beside all the positive impacts, some projects impact on the environment negatively. This is why the developed countries of the European Union and the world in their legislature began to regulate environmental protection, bringing numerous legal acts which, among other things, are project related. Guided by this fact, the paper highlights the key elements in the projects' environmental impact assessment and gives a short review of the EU legal framework in this area. Emphasis is placed on the directives on the assessment of the impacts of certain projects on the environment and their amendments. In order to reduce the negative impact on the environment, a substantial number of important elements in the procedures of environmental impact assessment and decision making have been introduced, and the legislation instruments have continuously been reviewed and improved.
Environmental Impact Assessment: Integrated Evaluation of Bridge Construction Project in Bangladesh
International Journal of Advanced Geosciences
Environmental Impact Assessment (EIA) may provide a mechanism for executing sustainable development and it is also becoming a very significance revision before authorizing of any project plan. EIA helps to decision making process whether the project is beneficial or harmful effects for the environment. Both on site and off site environmental impacts can be reduced through undertaking EIA for any bridge construction activities. This paper mainly concentrates on to find out potential environmental impact during the construction, operation and maintenance phase of the project using different matrix method. It also finds out the effective mitigation measures of the adverse impacts that will be helpful for the surrounding environment. Primary data were collected from field survey, focus group discussion. Most of the impacts and other consequences are identified based on public perception and the interview of the key personnel’s. Secondary data were also collected for conducting the resea...
Environmental Impact Assessment (EIA) of Infrastructure Development Projects in Developing Countries

Environmental Impact Assessment (EIA) is a tool used to identify the environmental, social and economic impacts of a project prior to decisionmaking. The process leads to the selection of the projects on the principle of sustainable development, so that the adverse effects of the new developments are mitigated through proactive and rational decisions making. Over the years, EIA has not been practiced holistically in the developing countries and particularly in South Asian Nations. However in the last few years Governments, environmentalists, researchers, media and communities of these countries have formulated sufficient legislative and institutional frame work for the EIA. In this paper, an overview of the EIA practices in developing countries and particularly South Asia, have been given, with special reference to the developments in Pakistan. The creation of awareness and formulating legislation has thus forced the countries to abandon many developmental projects, which were detrimental to the environment Some of the basic flaws in the EIA of a mega project (Zero Point Interchange Project-ZPIP0 have been highlighted. .

Building and Environment, 2005
A methodology which can be applied to the environmental impact study (EIS) and which facilitates to analyse the urban variables as a whole is explained. The work can be done in different scales (urban sectors and areas) which depend on the analysis complexity degree. This would allow to qualify and to quantify the local and regional environmental impact. Different concepts, methods and techniques have been considered and conveniently integrated. A body of relational decision matrices has been developed, in which the magnitude, sign, significance and temporality impact concepts are included. Different indices levels have also been developed. r

Environmental impact assessment (EIA) is a framework to provide all the socioeconomic and environmental impacts of mega projects for sustainability. Section 12 of Pakistan Environmental Protection Act (PEPA) 1997 regulates EIA procedure for mega projects that need to be approved by the respective Environmental Protection Agency (EPA) to reduce environmental impacts. This study identified inadequacies linked with EIA procedures of CPEC western road project initiated from Rehmani Khel to Kot Balian (package-2A). To evaluate EIA procedures for the selected road project, an EIA index has been formulated based on questionnaire responses. The respondents of this study included environmental experts, social experts, and consultants from the relevant departments. The secondary sources involved a comprehensive literature review and approved EIA reports of CPEC road project. For testing variables, statistical analysis, i.e., the gamma test, correlation analysis, and factor analysis were used....
" ENVIRONMENTAL IMPACT ASSESSMENT (EIA) AS A TOOL TO ACHIEVE THE SUSTAINABLE DEVELOPMENT "
As the word Environment gained its eloquence, in 1972 from the well focused United Nations Conference on the Human Environment which became the periphery of interrelating day to day human activities & its effect on Environment. Further the momentum has been attained in 1992, from the U.N Conference on Environment & Development named as Earth Summit which resulted in farming action plan to achieve Sustainable Development & so emerged the most relevant tool to assess a potential project for environmental impacts known as " EIA ". EIA envisages the future environmental impacts arising from upcoming project or a development activity providing suitable options & feasible measures for reduction of adverse impacts, making project friendly to lives of number of local habitants & hence maintaining sustainable livelihoods. Hence EIA is the best perceived tool for achieving the sustainability, i.e. desired balance between needs of today keeping in mind the demands of future generations. The approach sustainable development was introduced into the global scenario in the 1980s as a sphere co-relating economic development, the natural environment and people. This paper reviews the various analytical tools available to determine environmental impacts & there applications & respective comparison with EIA. The objectives of study to a large extent has been based on mapping & analysis of relevant flows of material, energy, environmental impacts & CO 2 generation per tonne of clinker & cement in Jaypee Sidhi Cement Plant, Sidhi (M.P.) –India, A unit of Jaiprakash Associates through Life Cycle Assessment tool. LCA methods is used for compiling & examining the inputs & outputs of energy, raw material, environmental impacts & emissions directly attributable to the manufacture & functioning of a production of product from " Cradle to Grave ". Production of cement involves the consumption of large quantities of raw materials, energy & pyro-processing. Also cement production is one of the largest contributors to global Co 2 emissions. Environmental impacts are taken in study as per national ambient air quality standards, 2009 of MoFF & CC. LCA methods are more precisely defined in ISO standards 14040 & 14044. Major thrust on following sections have been given in the study is goal & scope definition, inventory analysis, impacts assessment & interpretation. Potential impacts are also evaluated using the software & help of International Reference Life Cycle Data System Method recommended by European Commission in this study. Cost based analyses of above different segments were too taken in account in this research paper. Index Copernicus Value: 3.0-Articles can be sent to editor@impactjournals.us
