Excerpts;

Research on the Big Island’s coastal erosion, led by a University of Hawaii at Hilo graduate student, is being used to shape county planning policies.

Hawaii County is the only county in the state that hasn’t done research to understand the island’s shoreline changes.

Despite the island’s differing shoreline geology, the county’s initial general plan only required a development setback distance of 40 feet from shorelines across the entire island…

Terminal Groins Don’t Stop Erosion; Coastal Review (05-03-2016)

The Negative Impacts Of Groins, (02-12-2009)
The negative impact of groins on downdrift shorelines is well understood. When a groin works as intended, sand moving along the beach in the so-called downdrift direction is trapped on the updrift side of the groin, causing a sand deficit and increasing erosion rates on the downdrift side. This well-documented and unquestioned impact is widely cited in the engineering and geologic literature.

20,000 deaths since 1999: New report reveals deadly impact of extreme weather in France

Excerpts;

France is one of the most exposed countries in the world to the risks of extreme weather, a new report has found, with nearly 20,000 deaths linked to heatwaves, floods and storms in the last 20 years.

The report from the global climate charity Germanwatch ranked 183 countries around the world according to how exposed they are to extreme weather events – such as heatwaves, storms and flooding – linked to climate change.

France was ranked in the top 20 most exposed countries in the world, in the same bracket as India and Madagascar.The worst affected countries in the world were Puerto Rico, Honduras, Myanmar and Haiti…

La Faute-sur-Mer and l’Aiguillon-sur-Mer beaches, Vendée, France; By Claire Le Guern (03-2010)
The very last day of February 2010. It is 4:00 am. Howling winds, whipping rains, infuriated seas, and eight meter high (26 feet) crashing waves, are muffling the desperate cries for help…4:00 am… Twenty nine human lives are being swept away, drowned in the frigid and salty ocean waters. They were in their sleep, in their beds, in the comfort of their home. They did not understand, they could not react, most of them too old, too frail, or much too little to run for safety and climb on the rooftops, like most of the survivors did…
When daylight unveiled the disaster, French Prime Minister François Fillon held an emergency cabinet meeting and afterward called the storm a “national catastrophe.” French President Nicolas Sarkhozy, declared: “We have to find out how families in France in the 21st-century can be surprised in their sleep and drowned in their own houses.” Mr. Sarkozy added, “We have to shed light as urgently as possible on this unacceptable and incomprehensible tragedy.”
As much as this tragedy is utterly unacceptable, it is all too comprehensible and sadly, previously announced by warnings from many scientists, locals, and even more relevantly by an official 2008 report from the Vendée Equipment Department, DDE. The risks of marine submersion were known to the Vendée DDE, which strongly addressed and questioned coastal safety, citing in particular the fragile sea walls in L’Aiguillon-sur-Mer and La Faute-sur-Mer, as well as their existing location and development in flood-prone areas. “There is no doubt about the vulnerability of the Vendée coast to marine submersion”…

In the Afro-Caribbean heart of Puerto Rico, locals fight erosion

Excerpts;

Loíza, Puerto Rico, is filled with palm trees, unassuming bars, bomba music, beautiful beaches — and strong-willed locals who refuse to be forgotten.

The waves crashed loudly on the collapsed ruins of the Paseo del Atlántico, a walkway that once partially protected residents here from the volatile ocean. Erosion along this northernmost coast of Puerto Rico, nearly 20 miles east of San Juan, precipitated the promenade’s destruction for more than a decade and, in 2012, it finally fell into the Atlantic, exposing the Parcelas Suárez neighborhood to the water’s edge.

“The sea demands the space that we take away,” says Irizarry, sitting before an eroding Loíza beach…

They are dynamic places — and not just because they’re great for relaxing, surfing or people watching. With each crashing wave and changing tide, billions of pieces of sand and rock are constantly rearranged. This is what nature intended.

What it did not, some scientists say, are the buildings that tower over some of the world’s most popular beaches…

Sand is the second most consumed natural resource, after water. The construction-building industry is by far the largest consumer of this finite resource. The traditional building of one average-sized house requires 200 tons of sand; a hospital requires 3,000 tons of sand; each kilometer of highway built requires 30,000 tons of sand… A nuclear plant, a staggering 12 million tons of sand…Sand business is estimated to be a $70 billion industry, worldwide…!” Captions by “Sand Wars” Multi Award-Winning Filmmaker: Denis Delestrac (©-2013).
