Introduction To EIA
Environmental impact assessment (EIA) is the evaluation of the effects likely to arise from a major project or other action significantly affecting the environment.
It is a systematic process for considering possible impacts prior to a decision being taken on whether or not a proposal should be given be given approval to proceed.
Its focus is more strongly on the mitigation of any harmful environmental impacts likely to arise.
The use of EIA in project development may be regarded as a way of avoiding environmental impacts by using EIA at as early stage as possible in the development.
METHODOLOGY USED FOR EIA
Screening
The process to decide whether an EIA is required or not is generally called screening.
The preliminary study aims at identifying the possible environmental effects of the proposed activity.
Scoping
Identifying the main public concern about a proposal and for organising the scientific work for the assessment.
scoping process involves
Risk and Hazard Assessment
Risk assessment treats the effect of human activities on ecosystems
Hazard assessment treats the influence of natural catastrophes like earthquakes, landslides etc.
EIA and Decision making
EIA is in itself a tool for decision-making
Final report is preapered on the basis of all stages.
