Baseline Data Collection Questions and Answers

1.

The on-site monitoring data is known as...................data.

Exam Year(s)

MH SET - 2018, SET Exam - 2018,

Answer: B

On-site monitoring data is primary data.

Primary data is collected first-hand by the investigator for the study at hand, as in sampling air, water or noise at a project site during an environmental impact assessment. It is the most direct and specific evidence.

Secondary data has already been collected by someone else, such as published reports, census figures or earlier studies, and tertiary sources compile and summarise those. 'Numerical' describes the form of data, not its source, so it is not the category asked for.

Answer: D

Baseline data describe the existing environmental status of the identified study area.

Before a project is assessed, the EIA records the present condition of air, water, soil, noise, ecology and socio-economic factors in the study area, usually over one season. These baseline data are the reference against which the project's predicted impacts are measured and later monitored.

Cost-benefit analysis, risk assessment and the prediction of environmental consequences are later parts of the EIA that use the baseline; they are not what the baseline itself describes.

3.

Which of the following is correct for environmental setting process of EIA ?

Exam Year(s)

MH SET - 2025, SET Exam - 2025,

Answer: B

The environmental setting in EIA is the description of the affected environment.

After identifying the impacts a project may have, the EIA describes the existing, baseline conditions of the environment that the project could affect: air, water, soil, noise, ecology and socio-economic conditions within the study area. This baseline, also called the description of the environmental setting, is what predicted changes are measured against.

Describing the 'total environment' is neither possible nor useful; the study is limited to what the project can affect. The non-affected environment is outside the scope by definition. The social environment is one component of the affected environment, not the whole of it.
