Merida, Yucatan — With $50 million pesos contributed equally by the state and federal government, a program to combat beach erosion now reaches Chicxulub and Uaymitún, some of the beaches most affected by the loss of sand.
First stages of the project are nearing completion in Chuburná and Chelem, where 6.4 miles of beaches were addressed in a collaboration with the Secretariat of Environment and Natural Resources and UNAM’s Sisal campus. As a test, 200 groynes or spurs built 50 meters apart were installed to collect sand. Several meters of beach were reportedly replenished.
Coastal erosion has worsened in Yucatan over the last 20 years, a period in which UNAM has studied the ocean currents that carry sand away and deposit it elsewhere.
Erosion not only threatens the homes located near the beach, but also affects fisheries, the conservation of mangroves and salt industry, and the coast becomes more vulnerable to the impact of hurricanes, said the Federal Attorney for Environmental Protection (Profepa).
