Regional Assessments of Human Impact

The project to assess and map the change in cumulative human impacts builds on and is related to a number of other past and ongoing projects. In particular, we have applied the approach of mapping cumulative human impacts to the ocean in a number of regional contexts.

The framework for mapping cumulative human impacts to the ocean can be applied at any scale, local to global, and to any kind of ecosystem (marine, freshwater, or terrestrial). We have led a number of efforts to develop these maps at regional scale and have several ongoing projects for additional regions (listed below). Many other efforts around the world have been conducted independently; these can be found by searching the list of papers that have cited our original publication from 2008.
