Estimating Environmental Impacts Of New Roads Environmental Sciences Essay

Estimating Environmental Impacts Of New Roads Environmental Sciences Essay important Roads Western Australia Public Environment Report 2008 New Transportation projects nowadays is noticeably change magnitude across nations all around the world, especially the aspect of constructing innovative alleyway and highway networks, due to the staggeringly unstoppable increase in the population of people on earth, thus, the demand of life resources, the need of moving from one place to another (from location A to location B) is also increasing, in response to that governments of different countries atomic number 18 spending billions of dollars each year just to enhance and rise up the transportation networks, focusing on the local passway and highway networks, this movement of development was noticeable afterwards the war world II. CUsersEmadDocumentsUniversity ProjectsYear 4 ((2012 2013))Highway DesignAssignmentsAssignment 1ReferencesRoad and The milieu.jpgAccording to the Central Intelligence Agency (CIA) 2008, the United Arab Emirates has paved roadstead of 4,080 km (including 253 km of expressways), while the United States of America has paved roads of 6,506,204 km, this shows the huge increasing demand on paved roads.Road projects tramp be sproutn as an indication of how urban the country is, the much certain the roadway network the better the economy, because it provides more access to different locations with little travel time, thus it provides more jobs, health services and education. But as they say eachthing has its own price, developing virgin roads can bear any(prenominal) bad impacts on the surround and the ecosystem surrounding the roads. In this report, both the positive and the electro detrimental impacts of new roads and highway on the environment and ecosystem entrust be discussed, nevertheless the different types of somatogenetic environmental impacts.Impact of Roads on the EnvironmentFragile Nature by Joel Sartore Impact of new roads on the environment is becoming a more serious issue that governments should take distribute and be aw atomic number 18 of, because of the increasing demand on constructing new roadways nowadays, what comes after constructing a new road most of the times is a permanent change with the environment surrounding the road and may develop with time and lead to a serious damage with the ecosystem that cant be reversed, so intoxicating planning and constructing of new roads could have a huge impact on the surrounding environment and the ecosystem. On the other hand, well designed and operated new roads could have positive impacts on the environment and the ecosystem, yet nearlytimes it cost more money to avoid affecting the environment, so engineers and environmental scientists argon still trying to develop some new alternatives by using the new modern applied science techniques to avoid any interruption that the human kind is causing by dominating the environmental resources with out looking at the consequences of the actions. http//images.joelsartore.com/gallery/B/BEA014-00001.jpgRecently many environmental engineers and scientists are conducting Environmental Impact sagacity (EIA) reports to monitor and observe any physical impact on the environment and the ecosystem that may be ending because of constructing new roads, the fulfill of the environmental impact assessment may take some time, depending on the surface of the project and where its located.Types of Environmental Impacts Resulting from New RoadsThere a lot of environmental impacts of constructing new roads and highways that can be observed, they all can be categorised in three points set Impacts this impact will take effectuate in the near future.Indirect Impacts this impact will take effect in the further future.accumulative Impacts this impact will take effect in the far future after accumulation.*All these different impacts could have either a positive or a negative effect on the env ironment and the ecosystem. draw ImpactsDirect impacts on the environment can this instant occur during the process of the new road construction, for precedent the 1st step of constructing a new road between two cities separated by a discolour area or farm is removing the jet (trees, plants,,etc.) to place the roads gravel and asphalt (pavement), in general direct impacts are easier for the environmental assessment, because they are more predictable than the other two types (the indirect and the cumulative impacts), thus the impacts can be easily controlled to prevent any serious damage on the environment in case of the negative impacts.Direct Positive ImpactsAlthough that the direct impacts may have a lot of negative impacts, they have some positive impacts, for example, rechanneling a river or a water stream efficiency improve the water remembering of a village near by the road. Some developed countries are trying to merge the green and urban together, for example constructi ng new roads with rain retention or drainage systems by including some plants.

Air pollution could have the greatest impact on the environment (CO2 vehicles emissions) and noise pollution which all have negative effect on the ecosystem surrounding the road.Indirect ImpactsIndirect impacts can be also known as chain impacts, from the name we can tell that chain impacts require time to develop which will be warm to observe and measure during the construction of the new road.Indirect Positiv e Impactssome new modern roads that are being constructed have some facilities for pedestrians and bicyclists, thus this might help to reduce the impact of post pollution by reducing the number of vehicle users (CO2 emissions), likewise some new roads has a special lane for buses which will encourage people to use the bus more often and this might also decrease the air pollution.Indirect Negative ImpactsWhen it comes to negative indirect impacts, the 1st thing comes is deforestation and the decline in forest animals and bird species, in 1994 Rich et al. drew attention with his report that the decrement and extinction of some bird species is primary because of new roads (noise and light). In 1982 Burke Sherburne examined the population of wildlife of mammals and birds during and after construction of new roads, they found in that location is a little movement of both mammals and birds densities to different places.Cumulative ImpactsThese types of environmental impacts could be c alled as silent impacts, because the results of these impacts will need time to accumulate.Cumulative Negative Impacts orbiculate warming could be one of the cumulative impacts, many scientists are referring to the incremental percentages of CO2 for the last 5 decades, where they come from the emissions of factories, nevertheless, the vehicles emissions, thus, constructing new roads means more vehicles and more CO2 emissions.Environmental Impact perspicacity is the SolutionEnvironmental Impact Assessment also known as EIA, it should take place whenever there is a project that wanted to be constructed, the purpose of this environmental assessment is to check and consider every predictable impact (positive or negative) that may occur or affect the environment, it can be performed by taking study corridors, for example for green field roads a corridor of 10 100 km should be considered along the road that is being constructed, in order to assess and predict any changes that may occur surrounding that new road.ConclusionAs what we have seen in this report there are a lot of impacts may occur because of constructing new roads, some are positive impacts and some are negative impacts, some will occur in the long-term and some will occur in the short-term, so in order to control and to predict them environmental impact assessments (EIA) need to be do before constructing any new roads for a better environmentally friendly future.
