Beaches at Risk Due to the Increase in Atmospheric CO2

The appearance of dunes and beaches might soon be changing due to the increase in carbon dioxide emissions in the atmosphere, already a significant factor in the ongoing phenomena of climate change. The findings are the result of a study coordinated by the Institute for the Study of Anthropic Impacts and Sustainability in Marine Environments of the National Research Council (CNR-IAS) of Oristano, carried out in collaboration with Ca' Foscari University of Venice. The research, published in the journal Climatic Change, analyzed the chain reaction of effects on the marine environment triggered by the rise in CO2, estimating that from now to 2100 the accumulation of sediment at the base of the Mediterranean dune systems could fall by 31%, with erosion of beaches and an increased risk of flooding. The case study analyzed by the researchers was the Bay of San Giovanni, along the Sinis peninsula in Sardinia.

NUS Study: Mangroves Can Help Countries Mitigate Their Carbon Emissions

Geographers from the National University of Singapore (NUS) have found that coastal vegetation such as mangroves, seagrasses, and salt marshes may be the most effective habitats to mitigate carbon emissions.

Modern slavery promotes overfishing

Labour abuses, including modern slavery, are ‘hidden subsidies’ that allow distant-water fishing fleets to remain profitable and promote overfishing, new research from the University of Western Australia and the Sea Around Us initiative at the University of British Columbia has found.

New UMBC Research Suggests Need to Rethink Goals of Global Reforestation Efforts

Many countries have made commitments to restore huge areas of forest as part of the Bonn Challenge, organized by the International Union for Conservation of Nature. For example, Costa Rica has promised to preserve 1 million hectares (3,861 square miles) of forest by 2020—about 20 percent of the nation’s total area. However, a new paper in Conservation Letters suggests that quickly reforesting large areas may not be the best strategy to yield many of the benefits forests can provide.

The Secret behind Coral Reef Diversity? Time. Lots of Time.

Strap on a diving mask and fins and slip under the crystal-clear water near a coral reef in Indonesia, Papua-New Guinea or the Philippines, and you'll immediately see why divers and snorkelers from across the world flock to the area. Known as the Coral Triangle, the region is famous for its unmatched diversity of reef fish and other marine creatures.
