An Environmental Impact Assessment (EIA) is a systematic process used to identify, predict, and evaluate the environmental, social, and economic impacts of proposed projects before decisions are made. It aims to prevent, reduce, or offset adverse impacts, ensuring sustainable development by integrating environmental considerations into project planning and design.
An EIA is necessary to inform decision-makers about the potential environmental consequences of projects (e.g., mining, infrastructure) early in the planning process. It covers impacts on biodiversity, climate, air, water, soil, landscape, and human health and typically involves seven key steps: screening, scoping, baseline data collection, impact prediction, mitigation planning, public consultation, and monitoring.
