The management and conservation of the world's oceans require synthesis of spatial data on the distribution and intensity of human activities and the overlap of their impacts on marine ecosystems. We developed an ecosystem-specific, multiscale spatial model to synthesize 17 global data sets of anthropogenic drivers of ecological change for 20 marine ecosystems. Our analysis indicates that no area is unaffected by human influence and that a large fraction (41%) is strongly affected by multiple… 
Mapping cumulative human impacts to California Current marine ecosystems
Quantitative assessment of the spatial patterns of all human uses of the oceans and their cumulative effects is needed for implementing ecosystem‐based management, marine protected areas, and ocean
Cumulative Human Impacts on Mediterranean and Black Sea Marine Ecosystems: Assessing Current Pressures and Opportunities
Quantification and mapping of the cumulative impact of 22 drivers to 17 marine ecosystems reveals that 20% of the entire basin and 60–99%" of the territorial waters of EU member states are heavily impacted, with high human impact occurring in all ecoregions and territorial waters.
Spatial and temporal changes in cumulative human impacts on the world's ocean
This work calculates and map recent change over 5 years in cumulative impacts to marine ecosystems globally from fishing, climate change, and ocean- and land-based stressors and affirm the importance of addressing climate change to maintain and improve the condition of marine ecosystems.
Fine-Scale Cartography of Human Impacts along French Mediterranean Coasts: A Relevant Map for the Management of Marine Ecosystems
To map and quantify the main pressures exerted on near-coast marine ecosystems, at a large spatial scale though in fine and relevant resolution for managers, this work should contribute to prioritize environmental needs, as well as enhance the development of indicators for the assessment of the ecological status of coastal systems.
Combined effects of human pressures on Europe’s marine ecosystems
The results suggest that Europe’s seas are widely disturbed, indicating potential discrepancy between ambitions for Blue Growth and the objective of achieving good environmental status within the Marine Strategy Framework Directive.
Identifying and addressing the anthropogenic drivers of global change in the North Sea: a systematic map protocol
Background Anthropogenic pressures on marine ecosystems have increased over the last 75 years and are expected to intensify in the future with potentially dramatic cascading consequences for human
Local Drivers of Change in Southern Ocean Ecosystems: Human Activities and Policy Implications
Local drivers are human activities or processes that occur in specific locations, and cause physical or ecological change at the local or regional scale. Here, we consider marine and land-derived
Managing the middle: A shift in conservation priorities based on the global human modification gradient
A cumulative measure of human modification of terrestrial lands based on modeling the physical extents of 13 anthropogenic stressors and their estimated impacts using spatially explicit global datasets with a median year of 2016 suggests that most of the world is in a state of intermediate modification and moderately modified ecoregions warrant elevated attention.
Cumulative Impact of Societal Activities on Marine Ecosystems and Their Services
The aim of the current research has been to develop a comprehensive package of tools to assess the environmental impacts of societal activities under different maritime spatial planning proposals.
The Impact of Climate Change on the World’s Marine Ecosystems
Although there is considerable uncertainty about the spatial and temporal details, climate change is clearly and fundamentally altering ocean ecosystems and will continue to create enormous challenges and costs for societies worldwide, particularly those in developing countries.


Marine Ecoregions of the World: A Bioregionalization of Coastal and Shelf Areas
ABSTRACT The conservation and sustainable use of marine resources is a highlighted goal on a growing number of national and international policy agendas. Unfortunately, efforts to assess progress, as
Impact of Humans on the Flux of Terrestrial Sediment to the Global Coastal Ocean
Global estimates of the seasonal flux of sediment, on a river-by-river basis, under modern and prehuman conditions are provided, showing African and Asian rivers carry a greatly reduced sediment load; Indonesian rivers deliver much more sediment to coastal areas.
Technical Report: Human Alteration of the Global Nitrogen Cycle: Sources and Consequences
This report is confident that human alterations of the nitrogen cycle have increased the quantity of organic carbon stored within terrestrial ecosystems and caused changes in the composition and functioning of estuarine and nearshore ecosystems, and contributed to long-term declines in coastal marine fisheries.

This contribution, which reviews some broad trends in human history and in the history of fishing, argues that sustainability, however defined, rarely if ever occurred as a result of an explicit
Historical Overfishing and the Recent Collapse of Coastal Ecosystems
Ecological extinction caused by overfishing precedes all other pervasive human disturbance to coastal ecosystems, including pollution, degradation of water quality, and anthropogenic climate change.

Global Trajectories of the Long-Term Decline of Coral Reef Ecosystems
Records are compiled, extending back thousands of years, of the status and trends of seven major guilds of carnivores, herbivores, and architectural species from 14 regions that indicate reefs will not survive without immediate protection from human exploitation over large spatial scales.
Polar marine ecosystems: major threats and future change
This review of polar marine ecosystems covers both the Arctic and Antarctic, identifying the major threats and, where possible, predicting their possible state(s) in 2025. Although the two polar
