New science and software make Belize coastal zone management plan better for people and the environment. With historic expansion of coastal and ocean development, ecosystems like coral reefs and mangrove forests are put at unprecedented risk. Yet, planners often lack good information about how human activities will impact shoreline and ocean habitats now and in the future. This study developed the information the Belizean government sought to make informed management decisions....

Worldwide ship traffic up 300 percent since 1992

This item was filled under Climate
Maritime traffic on the world's oceans has increased four-fold over the past 20 years, likely causing more water, air and noise pollution on the open seas, according to a new study quantifying global ship traffic. The research used satellite data to estimate the number of vessels on the ocean every year between 1992 and 2012. The number of ships traversing the oceans grew by 60 percent between 1992 and 2002. Shipping traffic grew even faster during the second decade of the study, peaking at rate of increase of 10 percent per year in 2011....
