Rivers deliver sediment from land to the ocean. This sediment contains nutrients which can feed microscopic algae in water. But, if there is too much sediment and nutrients, delivered by floods from land-based erosion, algal blooms can occur that have negative effects on the Great Barrier Reef.

The challenge is that sediment comes from many different locations and we need to know … [more…] “To fix the reef we first need to fix the land – but where do we start?”

Elevated concentrations of strontium, an element associated with oil and gas wastewaters, have accumulated in the shells of freshwater mussels downstream from fracking wastewater disposal sites, according to researchers from Penn State and Union College.

"Freshwater mussels filter water and when they grow a hard shell, the shell material records some of … [more…] “Fracking wastewater accumulation found in freshwater mussels’ shells”

83% decline of freshwater animals underscores need to protect, restore freshwaters

Certain groups of animals are declining at an alarming rate—and none more so than those living in freshwater.

This year’s Living Planet Report shows that populations of animals—including mammals, birds, fish, reptiles, and amphibians—plummeted by 60% between 1970 and 2014. But those living in freshwater are experiencing a far more drastic decline: 83% since 1970. It’s a sobering statistic and one tied directly to the ever-increasing pressures that people are … [more…] “83% decline of freshwater animals underscores need to protect, restore freshwaters”

Wetlands are among the most valuable ecosystems on Earth, rivaling tropical rainforests in their biological productivity. Historically, wetland systems sustained civilizations by providing people with food and freshwater and protecting communities from flooding and storm surges.

Prior to European settlement of the United States, the American wilderness included a remarkable abundance and diversity of wetlands, ranging

26 August 2018: WWF has published a report that highlights the capacity of healthy rivers to help mitigate natural disasters, among other less valued benefits. The publication provides a framework for improving how societies measure, value, and promote rivers’ diverse benefits. It also offers solutions to support better decisions and management.

STORY HIGHLIGHTS

  • The report shows that 19% of global GDP comes from watersheds with high or very high water
