Monitoring is fundamental to environmental impact assessment (EIA) both to assess adherence to standards and to support management options. The use of indicators assures that a monitoring program addresses only the key variables associated with significant environmental impacts and also improves monitoring communication and reporting processes. This paper develops a conceptual framework to design and assess an environmental post-decision monitoring program under EIA procedures - INDICAMP. It also discusses how current indicator frameworks can be used to design and evaluate the performance of environmental monitoring programs in projects. A coastal infrastructure case study demonstrates the usefulness of this methodology.
