Environmental and Social Impact Assessment (ESIA) is a process of identifying, predicting, and evaluating the likely environmental, socio-economic, and cultural impacts due to the implementation of a project, and to propose mitigation actions together with management and monitoring measures; not only to reduce negative impacts but also provide positive contributions to the natural environment and well-being of the community.
The general format of the ESIA report is as follows.
Chapter 1 : Introduction to the project
Chapter 2 : Description of the project
Chapter 3 : Analysis of alternatives
Chapter 4 : Description of the existing environment (physical, biological, socio-economic, and cultural)
Chapter 5 : Assessment of anticipated impacts (environmental, socio-economic, and cultural) due to the implementation of the project
Chapter 6 : Proposed mitigatory measures
Chapter 7 : Contingency management plan
Chapter 8 : Environmental and social management plan and monitoring plan
Chapter 9 : Extended cost-benefit analysis
Chapter 10 : Conclusions and recommendations
The Central Environmental Authority (CEA), Sri Lanka, has established a legal framework for the Environmental Impact Assessment (EIA) process in Sri Lanka has been laid down in the National Environmental Act (NEA) in 1980 and its subsequent amendments. Hence, EIA has become a mandatory requirement for the establishment of projects in Sri Lanka under the National Environmental Act.
