How much have humans affected the population of other species on the planet? A new methodology for documenting the cumulative human impacts on biodiversity aims to answer this question.

Dubbed EPOCH -for Evaluation of Population Change- the methodology was developed by a group of scientists from universities in Europe, Asia, and North America. It provides a standardized framework for organizing disperse data on individual species or populations of animals and plants that have been affected by urbanization, pollution, fishing, hunting, over-harvesting, and other anthropogenic activities.

The Sea Around Us’ Deng Palomares and Daniel Pauly have just added a new item to their long list of publications: a chapter in Elsevier’s book Coast and Estuaries: The Future.

In their contribution, titled “Coastal fisheries: the past, present and possible futures,” Palomares and Pauly highlight the importance of coastal fisheries by pointing out that they made up 55 per cent of global marine fisheries catch from 2010 to 2014.

Researching and reporting on overfishing and underreported fish catches is not an easy task.

Nevertheless, for the past 18 years, the Sea Around Us has taken on this mission and nowadays its global reconstructed catch data has become a point of reference for scientists, conservation practitioners, fishers, and fisheries managers across the world.

But getting this information and the associated implications to the general public, and inspiring people to take action on it, is a whole different story. Fortunately, filmmaker Alison Barrat, from the Khaled Sultan Living Oceans Foundation, understood how important it is to spread the word about the true amount of fish we are taking out of our oceans and, with the support of the Smithsonian Channel, Rare and the Sea Around Us, produced and directed the documentary An Ocean Mystery: The Missing Catch.
