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

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…

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.
Seawalls: Ecological effects of coastal armoring in soft sediment environments; Science Daily (07-24-2017)
For nearly a century, America’s coasts — particularly those with large urban populations — have been armored with human made structures such as seawalls. These structures essentially draw a line in the sand that constrains the ability of the shoreline to respond to changes in sea level and other dynamic coastal processes…
Rethinking Living Shorelines, By Orrin H. Pilkey, Rob Young, Norma Longo, and Andy Coburn;Program for the Study of Developed Shorelines / Western Carolina University, March 1, 2012, Nicholas School of the Environment, Duke University
In response to the detrimental environmental impacts caused by traditional erosion control structures, environmental groups, state and federal resource management agencies, now advocate an approach known as “Living Shorelines”that embraces the use of natural habitat elements such as indigenous vegetation, to stabilize and protect eroding shorelines.
Let’s end war with ocean, Op-Ed by Orrin H. Pilkey
The immediate future most certainly holds more miles of sandbags, resulting in more narrowed and ugly beaches.But this trend can be halted and reversed. Now is the time to make peace with the ocean.The time is now to stop sandbagging, both physically with no more shore-hardening structures, and politically with no more exceptions to the intent of the rules, no more undermining existing legislation, and a return to enforcement…
