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.
Relationship between Highway Constructions and Natural Habitat, A Case Study of İzmir Highway
Natural habitats and ecological systems provide living space for one or more living beings, and they are the source of biodiversity on Earth. Integrity of ecosystems impetuously collapse due to unplanned urbanisation, misuse of lands and excessive consumption of natural resources by human beings. Additionally, monitoring studies are not sufficient to plan preventions. The main aim of this study is to set a precedent by monitoring the damage, the pressure and time-dependent changes, which are caused by highway projects planned without analysing ecosystem flexibility, on natural habitats through the use of remote sensing technique and GIS. The effects of highway projects on habitats are investigated with respect to two different points of view. The first one is that highway projects directly invade and divide habitats. The other one is that highways become centre of attractions for residential and industrial zones, and demand for settlements increases around highways. The research area of this study is the most seriously affected natural area in Aegean region where Izmir-Aydin highway passes through. The changes in the research area in terms of land usage from 1984 to 2014 were analysed by satellite images. The size of industrial and residential zones in the research area was 138 ha in 1984. The size of industrial and residential zone has increased by 1.225% and reached to 1.690 ha as industrial and residential zones became denser throughout the highway. As a result of this study, it was determined that Izmir-Aydin highway has irreversibly split and destroyed substantial part of the natural habitat.
Impacts of highways on land uses: the case of Antalya–Alanya Highway
Journal of environmental protection and ecology
. Highways, which are passing through the areas, not only damage the natural enviroment but also cause various ecological problems. To minimise these effects, an approach that takes the natural assets of highway route and land use developments into account at planning stage is very important. The Antalya-Alanya highway is one of the important highway of Turkey because it passes through many touristic places, agricultural lands, settlements and natural areas. determination of the impacts of the highway on the natural resources is of importance for the sustainability of the regional tourism and agriculture. in the present study, a variety of negative externalities of highways are investigated, including the environmental problems caused as a result of the selection of particular routes and those that arise out of the use of the said roads. direct impacts are caused by the road itself that is to say, by road building processes such as land consumption, removal of vegetation, and severa...
Developing Guidelines for Environmental Impact Assessment of Kashmir Underpass Project in Faisalabad
Engineering Heritage Journal, 2020
Road development projects are important as they provide economical, political and social benefits but delays can occur. EIA is conducted for every project as required by the Environmental Protection Act of 1997 and the Environmental Policy of Pakistan for the purpose of ensuring mitigation of environmental impacts due to project activities. The Kashmir Underpass project in Faisalabad is assigned to FDA, for the purpose of satisfying growing need of traffic load due to population increase in surrounding areas in newly developed societies. This research examines the different factors of project affecting the environment. Questionnaire approach was utilized to gain insights of environmental impacts due to the project. Results showed that 93% of respondents didn’t knew about EIA and why it is necessary. Respondents were facing impacts from dust particles, noise, traffic, business loss etc. These impacts were analyzed and guidelines were developed for EIA of Kashmir Underpass Project.

It is commonly known that highways cause comprehensive environmental effects during construction and operating stage. Many countries have started to use and practice new concepts such as; sustainable transportation, highway managément to decrease naturaland social negative effects of transportation on envirohmehtThe research area has a total surface of 6 210,26 ha which includes 500 m wide away from North and South side of the highway and 60 kin long route within the Adana urban boundary which is lying between " Adana West side" (Tarsus paying Office) and " Adana East side" (Gaziaritep paying office) at TAG (Tarsus-Adana-Gaziantep) highway. To simplify the traffic on that side of the highway entrance and exit ramps from the 7 different points (reciprocal 14 entrances and exits) were added for urban traffic access in recent years. Thus, intensity of usage has been increased.- The environmental problems such as; noise, soil, air, arid visual pollution have been increased by the intensity of traffic. The aims of the study were to 1) investigate the natural and socio cultural structures of TAG highway which take place in Adana urban boundary and 2) determine the environmental ^robiekns such as noise, soil and visual pollution on thenatùral environment and human health, and then improve new suggestions ’ according to sustainable aspect to reduce these problems on the city. We studied Pb in the soil and it has bèeit found under the limits according to thè Soil ProblemControl Regulation dated 10.12.2001. Besides, we determined noise measurement at 126 points to establish the noise problem and then results have been compared with the regulation; of Environmental Noise Assessment and Management Regulation on Environmental Noise Limit Values dated in Q7/0$/i6Q8. It has been deterauned that while maximum immediate measurement has been exceeded the limitation at 70 noise measurement points, according to average values have been exceeded at 35 noise measurement points. Planning and design principles oriented tangible suggestions have been improved to decrease negative effects of the highway on the natural, physical

Pakistan has constantly prioritized the development of roads and motorways as they are they are reflective of nation’s economic and physical condition. However, poor highway planning, design, and construction can have a negative impact on the environment and can lower the quality of life for inhabitants. Therefore, eco-friendly roadway/motorway planning, and construction approaches are crucial for reducing environmental, social, and economic damages. Currently, environmental impact assessment (EIA) is the prevalent method for assessing and evaluating the environmental impact of road infrastructure projects. Still, this conventional approach focuses primarily on development projects and lacks strategic insight. Hence, the world is now focusing on integrating and implementing SEA as a realistic approach for executing a sustainability plan in every area, including the infrastructure and transportation sector. Pakistan invests a considerable portion of its annual budget on infrastructure, particularly roadways; therefore, it must incorporate the changing trends and parameters into the planning and developing phase. thus, current research aims to incorporate SEA into the strategic planning of motorway/highway development by conducting a desktop study using secondary sources, including research articles and EIA reports, to analyze the environmental and socioeconomic effects of motorway/highway by identifying the direct, indirect, and commutative impacts. The alternatives are assessed using impact criteria and indicators to choose the best sustainable option for achieving the required objectives. our study is a pioneer work to integrate SEA into the planning process for highway construction, which would act as a baseline and an advisory tool for the decision-makers to incorporate SEA in Pakistan’s strategic development planning.

associated with road construction projects caused insignificant environmental impacts. No adverse impacts were seen in respect of sensitive habitat, wildlife, cultural heritage and endangered species etc. Even the use of borrow material from the vicinity of the project was not likely to cause such changes which may be irreversible or non-mitigable. Air and noise pollutions are the main issues of operation phase of the project but both are not foreseen to cross the limits of Environmental Quality Standards even in year 2030. (Except Sox and SPM which will cross the standard limits in 2015 and 2020 respectively). Social consultation was carried out during project study with officials and local communities. The aim was to solicit views on the proposed project and incorporate their concerns, demands and needs into the Environmental Management Plan (EMP) and Social Framework Agreement (SFA). Based on Environmental Impact Assessment (EIA), a Social Framework Agreement (SFA) has been proposed. However for future projects this instrument shall be prepared and made public when the project is approved and is ready for implementation.
The geographical area of this study located between the Army canal and Al-Sadr City is characterized by high-density population and lack of high-speed highways. This area is facing a low service level during traffic congestion resulting from an inefficient and poor road network. A traffic study has been done which recommended the construction of a new road parallel to the existing one, but with higher standards. This research aimed to evaluate, economically and environmentally, the feasibility of constructing a road for Al-Muthanna highway. This research is based on the hypothesis that the present road exhibits a relatively severe condition whereas the suggested road will be an asphalt pavement with a high-quality status. The traffic volume data was collected using a manual counting method for seven days from 7:00 am to 4:00 pm to quantify the average daily traffic and peak hour volume. In addition, the number of lanes required for LOS (C) was determined. The construction and maintenance costs for the road were also calculated. Reduction in road user costs for both the present and proposed roads were estimated as advantages. The economic study is done by balancing the reduced total road costs and their advantages to the basic year. The assumed discount rate in this study was 8%. To discover the economic viability, various standards were verified. These standards are Benefit-Cost Ratio (B/C), Net Present Value (NPV), and Internal Rate of Return (IRR). The outcomes revealed that NPV exhibited an encouraging value, that indicated that total benefits were larger than costs. Moreover, the B/C ratio was found to be more than 1.0, which was promising. Lastly, the IRR was found to be greater than 8% as suggested in the road projects.
Environmental Impact Assessment of a Rural Road Project : Network and Matrix Method
Environmental consciousness has taken a center stage in the planning and execution of development projects across the globe. It might not be as welcome as it seems to be because maximum damage has either been done or a road map has already been laid for further decimation and intoxication of natural resources. Today, the act of preserving has been replaced by the act of revival, which rings the alarm bell. In such a crucial time, the importance of Environmental Impact Assessment is conspicuously self-explanatory. Environmental Impact Assessment (EIA) is a process of evaluating the likely environmental impacts of a proposed project or development, taking into account inter-related socio-economic, cultural and human-health impacts, both beneficial and adverse. The cognizance of the impact on the environment because of a development project is not only crucial for avoiding the negative impacts but is also of paramount importance for maximizing the positive impacts on the environment. To fulfill the purpose of EIA, it should be thoroughly performed at different stages of development, which includes pre-construction stage, construction stage and post construction stage in the case of development project related to construction activity, which is the focus of our paper. On the basis of secondary data, impact identification networks are created for pre-construction, construction and post-construction phases, to identify the impacts. Only a flowchart showing the co-relation of impacts is not sufficient if the impacts need to be classified further. So, to identify the impacts more categorically, impact identification matrix is created. Using the networks and matrix, mitigation measures are suggested on a broad basis which serves as the conclusion of the thesis.
