The Marine Aggregate Extraction Risk Assessment Framework (MARA) provides a framework to help assess risks to the marine environment arising from dredging of the seabed. The Framework involves analysis of the probability of potentially harmful events occurring due to dredging activity and of sensitivities of various receptors to these hazards. It enables the risk of environmental impact due to dredging to be quantified and mapped. The approach helps decision-makers evaluate dredging licence applications and supports dredging operators to manage the dredging activity. It does however involve a significant amount of data processing. The MARA GIS project addresses this issue by developing a software package to operate the Framework data input requirements and the calculations, enabling the Framework to be conveniently and easily operated.
