Coastal and marine ecosystems are subject to a number of human-induced pressures associated with a variety of marine activities. In 2013 the Joint Nature Conservation Committee (JNCC) compiled an activities-pressures matrix which has since been endorsed by the Healthy and Biologically Diverse Seas Evidence Group (HBDSEG) and the UK Marine Monitoring and Assessment Strategy (UKMMAS) pressures sub group. The matrix identified 39 human use activity categories and 34 human pressure types. The links within this matrix are, however, largely based on expert judgement. There is therefore a requirement to validate the activities-pressures matrix so that it can be used to inform the management and monitoring of the marine environment.
The project was designed to provide greater transparency in the evidence that links human activities and pressures in the marine environment.
The aims of the project can be summarised as follows:

• To increase the transparency of the identified activity-pressure links through the provision of scientifically robust evidence, thereby validating the use of the matrix for the management and monitoring of UK seas; and

• To describe the confidence in the activity-pressure links based on the quantity and quality of the evidence found.

The resulting activity-pressures matrix has been structured so that it can be readily translated into a database by JNCC.

The P-A matrix database is available to download on the JNCC website. A user guide has been produced which is also available to download from the same page.

The P-A database and user guide can be accessed on this website:
