Half of the beaches on the Costa del Sol are at serious risk of sand loss – SUR
The loss of sand is a “serious risk” for half of the beaches in Malaga province, while another 40% are at “moderate risk” and 5% at slight risk, according to a report on the Strategy for the Protection of the Malaga Coast which the Secretary of State for the Environment, Hugo Morán, presented to mayors and councilors in Malaga on Tuesday morning…

Environmentalists and dam operators, at war for years, start making peace
The industry that operates America’s hydroelectric dams and several environmental groups announced an unusual agreement Tuesday to work together to get more clean energy from hydropower while reducing the environmental harm from dams, in a sign that the threat of climate change is spurring both sides to rethink their decadeslong battle over a large but contentious source of renewable power.
Trust nature: The best way to defend deltas against rising seas is with sand and mud
Sediment constantly and naturally replenishes deltas, keeping them — and all the people, fields, industries, cities and wildlife that rely on them — above the water. While scientifically proven, this surprising fact has struggled to gain much traction outside the small world of geomorphologists
More Than 500 Dams Planned in Protected Areas Around the Globe, Study Finds
More than 500 dams are planned or already under construction within protected areas around the world, according to a new study published in the journal Conservation Letters. The study is the first of its kind to quantify the global extent of dams constructed in protected areas, which can include indigenous areas, nature reserves, and national parks.
China’s Three Gorges Dam is one of the largest ever created. Was it worth it?
The Three Gorges Dam was designed to tame China’s longest river. But this summer’s record rains reveal its limited ability to control floods.
Global warming and illegal land reclamation add to severe floods in China
China has perennial flooding in summer but a combination of climate reasons and human behavior over decades of land reclamation and dam-building on nearby rivers, have contributed to a longer-than-usual duration and incessant rainfall in some regions.
The neglected, deteriorating and dangerous US dam infrastructure
More than 15,000 dams in the US would likely kill people if they failed, and at least 2,300 of them are in poor or unsatisfactory condition, according to new study.
Michigan dam failures force 10,000 to evacuate and could leave one city under 9 feet of water
Rapidly rising water overtook dams and forced the evacuation of about 10,000 people in central Michigan, where the governor said one downtown could be “under approximately 9 feet of water.” Experts are describing this as a 500-year event…
For now, river deltas gain land worldwide
River deltas rank among the most economically and ecologically valuable environments on Earth. People living on deltas are increasingly vulnerable to sea-level rise and coastal hazards such as major storms, extremely high tides, and tsunamis.

Chinese paddlefish extinct after surviving 150 million years
The Chinese paddlefish — one of the world’s largest freshwater fish — has officially been declared extinct after surviving some 150 million years. The giant species, which measured as long as 23 feet and weighed as much as 1,100 pounds, has been killed off by overfishing and dam construction.
Turkey’s Dam-Building Spree Continues, At Steep Ecological Cost
Nearly 90 miles of the historic Tigris River will soon be turned into a vast reservoir as Turkey completes the massive Ilisu Dam. While the government touts the project as a source of carbon-free electricity, it will displace 80,000 people and threaten a host of species.
