An environmental impact assessment (EIA) is an assessment of the possible impacts that a proposed project may have on the environment, consisting of the environmental, social and economic aspects.
Environmental impact assessment ensures that decision makers consider the environmental impacts when deciding whether or not to proceed with a project.
Analyzing developments in their spatial context during the initial stages of the EIA process expedites the identification of potential aspects and impacts that may have to be assessed while the process goes on.
Potential risk factors may be identified upfront and presented to the client to assess the viability of proceeding with the project.
An excellent tool that is increasingly important in the detection, description, quantification and monitoring environmental changes is Remote Sensing, which, in combination with Geographic Information Systems (GIS) and fieldwork, is an effective management tool.
