Palestinians Strive to Stop Gaza Shore Erosion with Concrete and Rubble

Authorities in Gaza have ordered giant concrete blocks to be dropped along the shoreline as increasingly heavy seas eat into beaches that provide residents of the densely populated strip with a rare public space for relaxation.

The blocks, placed on beaches and offshore, are aimed at countering waves that have grown in force, eating away the foundations of some seaside cafes and buildings.

But officials, residents of beach areas and experts fear the concrete barricades may not stand another stormy winter and that high waves could cause the collapse of the coastal road and threaten homes.

Nasser Thabit, an official in the territory's Hamas-run Ministry of Public Works and Housing, said waves that reached up to 6 meters last year as the effects of climate change have become more pronounced had begun to nibble at the edges of the road.

"There are several fragile areas in Gaza Strip that would be impacted directly from a rising sea. There is a fear that should the waves get higher it may cause a catastrophe, and drown many of those residential areas," he said.

Thabit said proper long-lasting intervention - vertical wave breakers and retaining walls along all or at least the most at risk parts of the coast - could cost around $150 million and called for help from international donors.

Measuring 375 square km (145 square miles), Gaza is one of the most densely populated areas in the world, with a population of 2.3 million Palestinians, most of them live in refugee camps, some facing the ocean.

In the Beach refugee camp in Gaza City, home to 90,000 people, residents have watched over recent years as rising seas have eroded the beach completely. Broken fridges, large tires and bricks have all been thrown along the shore to hold back the sea to no effect.

"The refugee camp has no beach, there is no place for people to sit, therefore, people are forced to pay to go north or (south)," said Abdel-Karim Zaqout, a history teacher, whose house in the camp borders the ocean.

With Gaza's land borders tightly controlled by neighboring Israel and Egypt, the seaside is a precious resource for people looking to escape their day-to-day stresses.

In Central Gaza Strip, Radwan al-Shantaf, from Al-Zahra city municipality, said the authorities had used large quantities of the rubble of houses destroyed in the May 2021 Israeli bombardment to barricade beaches.

He said high waves had forced the owners of a bank to evacuate to a building deeper into the city, and the operators of a power plant to build a concrete wall to reinforce the outer fence.

"The advance of the sea decreased the beach area and finished off recreation, cafes and beachgoers spaces," Shantaf told Reuters, standing in front of the concrete reinforcement.

In Tunisia's seaside town of Hammamet, bulldozers diligently shovel sand from a nearby desert onto a popular beach in an attempt to stop it from disappearing due to erosion.
"This beach is the postcard image of Hammamet," said environmentalist Chiheb Ben Fredj peering nostalgically at the town's iconic Yasmine beach.
"It has been seared in our minds since our childhood," he added, as laborers worked to restore the central Tunisian waterfront to its former sandy glory, reported Agence France Presse.
Like many other coastal areas in North Africa, severe erosion has led to many of Hammamet's sandy beaches vanishing in recent years, taking a toll on the holiday hotspot about 65 kilometers (40 miles) east of the capital Tunis.
Coastlines across the world are in a constant natural flux, with the seas claiming and depositing sediment.
But human activity, including coastal property development and offshore sand mining, significantly accelerates beach erosion.
Among other impacts, construction and coastal defenses in one area can stop sediment from traveling along a coastline, leaving existing beaches deprived of new material.
Studies have also shown the impacts of climate change, including rising temperatures and sea levels, exacerbate the phenomenon.
Tourism draw
In the Mediterranean, where the British National Oceanography Centre says sea levels have risen at a higher rate over the past 20 years than the entirety of the 20th century, shorelines are changing rapidly.
The sea is also warming 20 percent faster than the rest of the world, according to the United Nations.
Tunisia's coastline has been a major asset for the Mediterranean country with a struggling economy, as it aims to host some 10 million tourists this year.
Tourism accounts for up to 14 percent of the country's GDP, providing tens of thousands of jobs in a country where unemployment tops 16 percent and 40 percent among young people.
Tunisia has already lost more than 90 kilometers of beaches to erosion, according to official figures from last year.
Of the country's 570 kilometers of sandy beaches suitable for swimming, 190 kilometers are at imminent risk of disappearing, according to Tunisian reports.
A majority of the beaches most affected by erosion are located near cities.
Tunisia's environmental groups, as well as the government's Coastal Protection and Development Agency (APAL), blame the rapid erosion mostly on human activity and construction on the coast, which they say is further aggravated by climate change.
"Construction projects have not been designed to respect coastal dynamics," an APAL official told AFP.
'Not sustainable'
To save the Hammamet beach, one of Tunisia's worst-affected according to the World Bank, authorities last month began trucking in around 750 lorry loads filled with sand from the inland desert province of Kairouan, about 110 kilometers away.
APAL, which operates under the environment ministry, was in a race against time to refill the beach before the peak of tourist season.
But while the rebuilding of beaches, known as beach nourishment, may be a quick fix, "it's not a sustainable solution", said Ben Fredj.
"This sand may not last long," added the secretary general of the Environmental Education Association.
"It can be swallowed in a few days in the event of a storm", he said, as was the case in the summer of 2023.
The process can also prove expensive.
Coastal authorities estimated the cost of restoring sand to three beaches in Hammamet, Monastir and Sfax at 3.9 million Tunisian dinars ($1.25 million).
But for locals, restoring their priceless seafront is worth the money.
The Yasmine beach "is a showcase for Hammamet," said Narjess Bouasker, who runs the town's Menara hotel and leads the regional hotel federation.
"We must take back our beach that the sea has swallowed," she said, calling for a balance between safeguarding the landscape, cherished by locals and foreign visitors alike, and fighting coastal erosion.
"For us, the priority is not to touch the beauty of the city," she said.
Bouasker said she has seen increasing awareness among authorities, but refilling beaches with sand is still a gamble.
"We don't know how the sea will react", she added.
