· A matrix presentation has a better structure framework than the checklist approach. In fact, it makes a summarized analytical presentation of the project and environment-related checklists.
· Matrix structure allows for speculation of impact characteristics, albeit in a subjective way. This provides a gradation in the impacts, thereby providing a focus for further studies, verification, or discussions. It also helps in making priorities on some mitigation measures which are estimated to alleviate the impacts speculated.
· It presents an easily understood summary of a large number of primary impacts.
· It is a generalized but well defined approach, forcing a comprehensive consideration of environmental components and primary impacts.
· It is an easily performed process which can specify the overall character of a project early in the design phase.
· In an extended form, the method can include information about many impact attributes, and clarify the assumptions supporting the assessments.
· Matrices have low resource requirements.
