TITLE - Environmental Impact Assessment (EIA), it 's introduction, purpose, methods of EIA, EIA conducted in India, Environmental Impact Statement(EIS). INTRODUCTION : DEFINITION : An environmental impact assessment (EIA) is an assessment of the possible positive or negative impact that a proposed project may have on the environment, together consisting of the environmental, social and economic aspects. PURPOSE : The purpose of the assessment is to ensure that decision makers consider the ensuing environmental impacts when deciding whether to proceed with a project. The International Association for Impact Assessment (IAIA) defines an environmental impact assessment as "the process of identifying, predicting, evaluating and…show more content…
Some of the methods are GMP-RAM, INOVA etc.[8] • Fuzzy Arithmetic - EIA methods need specific parameters and variables to be measured to estimate values of impact indicators. However many of the environment impact properties cannot be measured on a scale e.g. landscape quality, lifestyle quality, social acceptance etc. and moreover these indicators are very subjective. Thus to assess the impacts we may need to take the help of information from similar EIAs, expert criteria, sensitivity of affected population etc. To treat this information, which is generally inaccurate, systematically, fuzzy arithmetic and approximate reasoning methods can be utilised. This is called as a fuzzy logic approach.[9] At the end of the project, an EIA should be followed by an audit. An EIA audit evaluates the performance of an EIA by comparing actual impacts to those that were predicted. The main objective of these audits is to make future EIAs more valid and effective. The two main considerations are: • scientific - to check the accuracy of predictions and explain errors. • management- to assess the success of mitigation in reducing impacts. Some people believe that audits be performed as a rigorous scientific testing of the null hypotheses. While some believe in a simpler approach where you
