Marine Pressures and Impacts


Coastal and marine ecosystems are subject to pressures associated with a variety of human activities. Concern over the possible impacts of anthropogenic pressures on these ecosystems has led to the development of national, regional, and global commitments that aim to preserve and, where possible, mitigate impacts on marine biodiversity. JNCC works to develop our understanding of how these human activities and pressures interact with the marine environment and thus what their potential impacts are.

Areas of work at JNCC include:

·         Research into the links between activities and associated pressures (e.g. fishing activity with abrasion pressure).

·         Collation, cataloguing and mapping of data showing the spatial location of marine activities and associated pressures.

·         Studies assessing the sensitivity of benthic habitats and species to marine pressures.

·         Mapping the exposure of marine biodiversity to human-induced pressures and determining how vulnerable they are to   associated pressures.


The information gained through this work can be used to:

·             Assist MPA designation and the provision of conservation advice.

·             Inform risk-based assessments in support of marine biodiversity monitoring.

·             Facilitate discussions on management measures for MPAs.

·             Advise marine industry in relation to environmental impact assessments (principally oil and gas, marine aggregate dredging, fishing and the renewable energy industry).

·             Inform the development of indicators to assess habitat condition (see Marine Strategy Framework Directive (MSFD))
