Impact Prediction Methods Questions and Answers

Q: The project characteristics and the baseline information is brought together by................of impacts.

They are brought together by identification of impacts.In environmental impact assessment, impact identification brings together the project characteristics, what the project will do and emit at each stage, and the baseline information on the existing environment, so that every potentially significant impact is recognised. Checklists, matrices and networks are the tools for this stage.Prediction comes next and estimates the magnitude of the impacts already identified. Evaluation then judges their significance. Assessment is the name of the whole process, not the step that first brings the two kinds of information together.

Q: Which of the following methods involves an explict and predefined relationship such as mathematical model for social impact prediction ?

The keyed answer is application specific predictive technique.Of the four options, only this one names a predictive technique built on an explicit, predefined relationship, such as a mathematical model fitted to the situation, which is what the question describes for predicting social impacts.Qualitative description and quantitative description describe the likely effects in words or in numbers; they do not depend on a predefined model of cause and effect. Relative comparison of the effects of alternatives ranks options against each other and likewise predicts no effect from a stated relationship. What could not be confirmed is the exact classification: no reference was found that sets out these four technique names, so the key is explained from the meaning of the options and not from a located source.

Given below are two statements, one labelled as Assertion (A) and the other labelled as Reason (R).

Assertion (A) : Indirect impacts are more difficult to measure, but can ultimately be more important.
Reason (R) : In areas where wildlife is plentiful, such as Africa, new roads often lead to the rapid depletion of animals.
Choose the correct answer.

A.Both (A) and (R) are true and (R) is the correct explanation.
B.Both (A) and (R) are true, but (R) is not the correct explanation.
C.(A) is true, but (R) is false.
D.(A) is false, but (R) is true.

Answer: B

Both statements are true, but the reason does not explain the assertion. Indirect (secondary) impacts of a project are harder to measure than direct ones and can in the end be more important, which is correct. The reason gives an example: new roads in regions rich in wildlife, such as Africa, open up access and lead to rapid depletion of animals. That shows one indirect impact, but it does not explain why indirect impacts are harder to measure or why they can matter more, so option B is correct and option A is not.
