Coastal marine ecosystems are at risk worldwide as a result of human activities, according to scientists at UC Santa Barbara who have recently published a study in the Journal of Conservation Letters. The authors have performed the first integrated analysis of all coastal areas of the world.
“Resource management and conservation in coastal waters must address a litany of impacts from human activities, from the land, such as urban runoff and other types of pollution, and from the sea,” said Benjamin S. Halpern, first author, who is based at the National Center for Ecological Analysis and Synthesis (NCEAS) at UCSB.
“One of the great challenges is to decide where and how much to allocate limited resources to tackling these problems,” he said. “Our results identify where it is absolutely imperative that land-based threats are addressed — so-called hotspots of land-based impact — and where these land-based sources of impact are minimal or can be ignored.”
