Environmental impact assessment (EIA) is a decision-support tool for those selecting whether to approve a development project. It gives information on the potential implications of projects to those responsible for the decision. The purpose of an Environmental Impact Assessment is to evaluate the potential ecological, socioeconomic, and wellness consequences of any project. This assessment indicates that those who decide details about the project development and validation are aware of the likely impact of the event; thus, they are more morally responsible. The goal of EIA is to make decision-making more informative and thorough while limiting, removing, or managing the adverse consequences of evaluating possible options, settings, or methods.

EIA is a subset of environmental assessment (EA) procedures. While EIA refers to individual projects, EA is a broader term that includes strategic environmental assessments (SEA) of policy, objectives, programs, and other types of evaluation. 

Types of Environmental Impact Assessment

The strategic environmental assessment encompasses various empirical and participatory methodologies aimed at incorporating environmental issues into strategies, goals, and initiatives and assessing the interrelationships with economic and social factors. SEAs are becoming increasingly relevant and necessary as development agencies focus on supporting specific projects to support the overall strategies and actions. However, while these assessments are primarily regarded as the best path forward, the process of moving from concept to action and then to results has been uneven.

Integrated environmental assessment and reporting attempts to demonstrate the cause-and-effect relationships between human and natural actions on the environment and the resulting changes in the environment in the effects of environmental change and the development of humans. More than simply knowing the state of the ecosystem should be the end outcome of environmental assessment. It should provide regulators and other users with recommendations for improving environmental management.

Social Impact Assessment

The processes of analysing, monitoring, and controlling the intended and unexpected beneficial and unfavourable social repercussions of planned interventions and any social change processes induced by those interventions are referred to as social impact assessment. Its main goal is to create a natural and human environment that is more self-sustaining and balanced.

Aim of Social Impact Assessment

• A Self Sustaining and Balanced natural and human environment
• A proactive approach to development and better development outcomes
• Planned interventions on behalf of several actors
• Adaptive management of initiatives, programs, and initiatives
• Analyse the concerns of interested and affected parties
• Recognize that social, economic, and biophysical impacts are intricately linked
• Analysis of the consequences that happened as a result of previous operations
• Analysis of social consequences of events, such as disasters, demographic change, and epidemics

Process of Environmental Impact Assessment

• Evaluating the Development Project
• Identification of the scope of the project
• Study of the current environmental status of the Zone
• In-depth assessment and calculation of the probable impact of the project that is being undertaken. The assessment should categorise the probable nature of impact (temporary and permanent)
• Detailed report and Suggestions – Environment assessment reports are required to be shared with all the stakeholders of the project with a detailed scope of impact and the plan of actions suggested for proper monitoring and mitigation of environmental impacts(negative)
• Dissemination of Information – The developmental project undertaken affects the people inhabiting the area; hence, after discussing the EIA report, the probable impact should be disseminated to that area’s population
• Project Decision – Authorities take decisions after considering the potential impact and benefits of the project, under the consultation and guidance of experts. The Deciding Authority is the Impact Assessment Authority
• Continuous Monitoring – After the project starts, the impact is constantly monitored to ensure adherence to the protocols and action plans for mitigation of environmental impact
• Risk Assessment – A continuous risk assessment is done for all the projects with changing scenarios. Inventory and possible Hazard analysis remain an ongoing process

The Goal of Environmental Impact Assessment

The goal of an EIA is not to force decision-makers to choose the least ecologically destructive option. It tries to make the impact on the environment of development apparent so that it is considered in decision-making. The technical parts of EIA, such as effect classification and prevention, as well as the assessment, monitoring, and dissemination of information, have been viewed as both a science and an art. Before delving more into EIA, it’s important to understand the sort of environmental change that must be considered.

Conclusion

The Environmental Impact Assessment (EIA) has been used since 1978 to analyse different river valley projects in the country. It was then expanded to include various other development operations. EIA is now required for over 30 different types of projects. The Environmental Protection Rules, 1986, allow for the imposition of certain restrictions on the construction, expansion, or modernization of specific projects without prior approval from the Environmental Impact Assessment Authority.
