2.7.3 Environmental Impact Assessment

welcome again today we continue to
stay on track towards the completion of the IB Environmental systems and societies syllabus topic two point seven point three describe and evaluate the use of
environmental impact assessments pristine climax forest nestled in the mountains a developing
society needing a source of energy the question should a rich coal deposit in these hills be exploited at the expense of the rich and diverse climax forest do you think that it’s worth clearing some of the forest to develop and what are some reasons for your perspective the government of this area however subscribes to this principle sustainable development development to meet the needs of the
present generation without compromising the ability of
future generations to meet their needs the classic balancing act between having some development and having some environmental protection
though it is with sustainable development as the goal that we have EIA environmental impact assessment an EIA is a method of detailed survey required in many countries before a major development ideally it should be
independent of but paid for by the developer such as survey should include a baseline study a measure of environmental conditions before development commences and to identify areas and species of
conservation importance the report produced like the one below is known environmental impact assessment or sometimes as an environmental
impact or an EIS the monitoring of this should continue for some time after the development and as you can see here an EIA is a very extensive document sometimes taking over two years to prepare or sometimes being prepared hastily after the developments already begun it depends on the conditions and the
levels of transparency and integrity within each administration but in general an EIA is a comprehensive document prepared by a team of experts so back
to our question should we exploit this pristine climax forest the administration that runs this region have decided to focus on sustainable development they have
decided to conduct an environmental impact assessment it’s not that EIA is required for
every project but if a project meets certain criteria
it’s necessary to investigate the environmental impacts in a bit more detail and suggest alternatives and to examine ways of preventing as much as possible the impacts while allowing the project
to proceed or perhaps not even a lot of the project to proceed this initial phase of looking at what the project entails the scale of it and deciding whether or not a full environmental impact assessment is
required it’s what we call screening where the laws of the country will
decide what scale project requires a full environmental impact assessment in most countries with EIA a project of the scale shown here in this map with these two peaks representing our mountains
and all of this area here the pristine climax forest and a railway line for connecting town a to town b where you will have coal mining a project of this scale is likely to qualify for full
environmental impact assessment and what follows from this is a phase of the process referred to as
scoping a very relevant phase for the environmental systems and societies student because it involves a coming together of stakeholders from all areas to identify the issues and as you can see here this involves a range of groups that have to come together to share their expertise and their ideas as we focus in on some of the special areas of concern the scoping this followed by a collection of the baseline data where is the environment right now? and where has it been going for the last
few years what are some trends? and now that the project is being
proposed what are some likely changes or impacts with option a maybe or with option b_ or with option c what would be the business as usual
or the trend assuming that no project is allowed this point of predicting what would happen in the future requires another kind of input but it’s very important to document where things are before we look at predicting where
things might go in the future this process of documenting the current state of the environment the pre development state of the
environment is referred to as the baseline data
collection following this through expert input of all kinds impacts are predicted possible alternatives are discussed and ways to reduce the impact are considered what then are some tools available for the prediction off the impact of this railway line from a to b for the purpose of exploiting coal in this pristine forest its first necessary to document the current state of the
environment and perhaps this state has already been documented perhaps we already have some data of (about)
the kind of trees and the diversity and the populations of different species
that live in this area and perhaps if there are any man made things like gas
lines and utility lines running through this area underground if there is a river running through the
area and documenting and bringing together information on the present state of the
environment is what we call that baseline data collection in years gone by it was necessary to overlay several maps
from different sources to bring together a composite picture of the environment but in the modern age of computer technology information from different sources about a particular area can all be lumped together in what we term the geographic
information system the g_i_s_ and this is a bringing together a composite of everything that we know about an
area so that environmental managers can quickly document the information that’s already there and
available about the area added to this of course is the power of
satellite imagery which can give us high quality resolution images of all areas of the earth this however does not mean that we would not go out into the field and
actually verify some of this for (because) ground verification is always good way to go and then of course there is the need to
include expert knowledge and knowledged of similar projects that had EIA’s completed (and) were audited or reflected upon to see what actual impacts did happen versus what impacts for predicted (birds chirping) if we proceed with the project and we decided to allow our railway line to go through the pristine climax forest then we need to get onto the field and
collect some baseline data so what tools have we considered so
far in our course that we might (can) use to help us collect some information on the diversity of of the plants and animals in this area perhaps we might need to
do a count of the number of bird species and the
number of nests that are going to be disrupted throughout the length of the
railway line the number of trees that would (will) have to be cut
down the species of these tees what other kinds of wildlife would be affected and how what would be the level of noise in the
area so there are a whole range of impacts to be
considered some which may involve social issues and not just issues of endangered species and wildlife some which may involve engineering
issues and with all of these issues in mind we decide whether or not the project
should go forward and if and when the project does
proceed then we need to monitor and monitoring should happen once
approval is given it should continue throughout the
project for there are certain mitigation measures
that might have been proposed in the EIA and it’s important for some independent regulatory body to visit the construction site to ensure that what might be written in the EIA report is actually carried out in reality for instance if there are certain special hours for the construction to
proceed and special periods of the year
designated for construction to proceed then it’s important that some regulatory body visits the construction company to insure that what was proposed in
the EIA report is translated into reality in the actual
construction (sound of a train coming) finally the railway is complete and now monitoring must continue monitoring is very important now because all of the experts and all of the input
and all of the effort that went into making a prediction now’s the time for us to be actually
test and to collect data to decide whether or not our predictions held true for we can go out into the field over the
next five years ten years as the coal mine is
explored firsthand information on what was the environmental impact of building ths railway line to exploit coal carrying out a post development audit a very very important part of the EIA because it is the part where we actually learn something at
the very end something that could be used in other
EIA’s for the data that we collect in the post development audit to make any sense it’s just as important for the baseline data to have been collected so we would have
a knowledge of what was there pre project so that if there’s a change post project we would be able to tell what the impact was documented here for you all of the phases of the EIA process it’s important to note that not every
project requires an EIA evaluate the use of environmental impact
assessments ecocentrists reject EIA as
corrupt and designed to gloss over abuse of the environment technocentrists see EIA as a waste of resources and they point to the use of advanced
technologies to address all possible issues arising out of a project from
pollution to species loss imagine that you are an
environmental manager in charge of the public meeting the scoping phase of an EIA i want you to identify some points that
you would highlight to address both the ecocentrist and technocentrist concerns

  • Thank you

  • well explained.. thanks

  • awesome…best EIA concept i ever understood !!!

  • whoever disliked this must be doing AP. excellent explanation!

  • Long live Dan Dubay! 

  • So helpful for my exam tomorrow! 

  • very helpful, but wtf is up with your audio editing? are you unable to speak in complete sentences?

  • Very good and simple explantion for abstract concept. Thank you for your effort much appreciated

  • Flood plain disaster in progress … https://goo.gl/kQLLFy

  • You are practicing and supporting the hunting of human beings on the land…. Capacity building for corporate criminals creating laws of forced entrapment of human beings held captive as slaves institutionalized … No different than Hitlers concentration camps… I just hope you degenerates know exactly what you are promoting and or studying!

  • NukeGate!!! Progressives help stop the deceptive madness. Check these recent Youtube videos out. They reveal the scandal that the nuclear industry has just pulled off and the new NEPA/EIS cover-up they are pulling off at this very moment under the Trump Administration. Check these recent Youtube videos out. They reveal the scandal that the nuclear industry has just pulled off and the new cover-up they are pulling off at this very moment under the Trump Administration.

    NukeGate 2.0: Nuclear Nonsense Piled Higher and Deeper!


    I’m an engineer. I checked the scientific and engineering facts out and can affirm that these videos are completely accurate. Almost no one, including myself, has been made aware of this cover-up and the explosive hazards it presents to the public.

    There could be public uproar once people begin to learn about these horrendous safety issues that have been covered up. These undisclosed safety issues are of such gravity that they may provide the basis for a national lawsuit. It also appears that this cover-up may demand a thorough Congressional investigation.

    Take a few minutes and review at least the first video. Then decide for yourself if this isn’t a scandal that could become a campaign and green energy issue.

  • Awesome lecture..
