Why Antigua’s Beaches Are Eroding — And What We Must Do About It

Why Antigua’s Beaches Are Eroding — And What We Must Do About It

Antigua & Barbuda is blessed with some of the most beautiful beaches on Earth.

But beneath the postcard perfection lies a growing crisis: beach erosion.

This is not a single-cause problem. It’s the result of multiple overlapping pressures — ecological collapse, poor coastal practices, sand removal, reef degradation, dredging, and a lack of serious study into how our beaches are actually formed and maintained.

If we want our children and grandchildren to inherit living beaches — not rock walls and imported sand — we need to understand what’s happening.

1. Our Beaches Exist Because Our Coral Reefs Exist

For thousands of years, coral reefs off Antigua’s coast grew upward toward the surface.

From Diamond Bank stretching miles toward the islands of the North Sound, reef structures once formed a vast natural barrier system busting up ocean ground swells in the winter months. 

• Healthy reefs break wave energy before it hits the shore.
• They produce massive amounts of sand.
• They create calm lagoons where beaches accumulate.

When reefs are alive and growing near the surface, they act like a natural seawall.

When they die and erode, they become rubble fields that no longer protect the shoreline.

The role coral reefs play in coastal protection is well documented by NOAA:
NOAA – Coral Reefs as Natural Coastal Protection

Today, many of these reef systems are largely degraded.

2. Why Have the Reefs Died?

Climate Change & Coral Bleaching

Warmer seas stress corals, causing bleaching events that reduce resilience.
NOAA – Coral Bleaching Explained

Overfishing — Especially Herbivores

Herbivorous fish like parrotfish (locally called chub) are essential to reef survival.

• They eat algae that would otherwise smother corals.
• They clean reef surfaces so new coral larvae can settle.
• They produce enormous quantities of sand.

When herbivores are removed:

• Algae takes over.
• Coral recruitment drops.
• Reef growth slows or stops.
• Structural complexity collapses.

The International Coral Reef Initiative summarizes this clearly:
Parrotfish: Key to Reef Survival

Over and uncontrolled fishing of herbivores continues to this day.

3. Parrotfish: The Unsung Sand Factories

Parrotfish scrape coral surfaces to feed on algae.

In doing so, they grind calcium carbonate skeletons into sand.

Scientific research has quantified this sediment production:
Yarlett et al. (2021) – Quantifying Parrotfish Sediment Production

When we eat parrotfish:

• We remove reef cleaners.
• We reduce coral recovery.
• We reduce sand production.
• We accelerate erosion.

The first first first thing we must do is completely ban the consumption of parrotfish for a period of ten years at the least. Other islands have full time bans in order to mitigate all the other effects hitting the our reefs. Mitigation is the name of the game when it comes to attempting to deal with climate change.

4. Sand Theft — “Just a Few Buckets”

Many people believe they have the legal authority to take “just a few buckets.” It was from something VC Bird once said I think.

But sand removal is regulated under the Beach Protection Act:
Beach Protection Act (Cap. 46)

Enforcement was strengthened in 2020:
Beach Protection (Amendment) Act 2020

Removing sand:

• Disrupts dune systems.
• Exposes root structures.
• Reduces natural storm buffers.
• Accelerates shoreline retreat.

Stealing sand — even a bucket — is not harmless and it's illegal for good reason. 

It is a serious crime against the people of Antigua & Barbuda and the environment we must protect for future generations. Sand has been stolen from every single beach in our country that has road access. I've seen sand taken from many beaches that do not have road access. Backhoes clear paths for trucks and sand is removed even from remote beaches. However the beaches where pickups cars or trucks can pull up to the sand are ones which have been really hit devastating sand removal for decades. Fort James and Runaway have been hit hard but are not unique. They just get bad ground swell. The terrible shape that those beaches are in cannot totally be blamed on the dredging of Saint John's. There are some small beaches on the other side of the harbour where you cannot get close to with your vehicle that are doing fairly well. Darkwood had hundreds of truckloads of sand taken from it after the storms in the 80s pushed it over the road into the swamp. Instead of putting it back on the beach, public works gave permission for industrial send money to take place. I've seen the same thing happening in crab Hill after storms. 2 weeks ago trucks took sand from Darkwood. Sand is taken from jabbawock almost daily. Ffreyes Beach, little ffreyes, Morris Bay, Cades Bay, Half Moon.... All of them have had endless sand taken from them so this thing isn't about any one thing but for sure government could make a major change in the way that we monitor and deal the stealing of OUR sand. Many people knew that it would take a toll but for some reason many more thought that the sand would never finish.

5. Seagrass, Dredging & Offshore Disturbance

Seagrass ecosystems trap and stabilize sand. They reduce wave energy and host sand-producing organisms.

The impacts of dredging on seagrass and coral are well studied:

• Dredging Impacts on Seagrass
• Dredging and Coral Health

For a country economically dependent on beaches, not fully understanding our sand budget is risky.

---

What Must Be Done

• Completely ban the consumption of parrotfish.
• Completely ban removal of sand from all beaches.
• Increase patrols, arrests, and convictions.
• Provide accessible imported sand (bagged & bulk).
• Regulate vessel beaching practices.
• Ban dumping rocks along shorelines unless proper studies are done.
• Stop dredging until sand budgets are scientifically understood.
• Make sure that extensive study is done by at least two different and independent firms who have expertise in environmentally friendly offshore sand dredging to figure it out before any dredging. Environmental impact assessment studies must be done by more than one firm independent of any contractor associated with the dredging or with the government. 
• Sand should not be taken from any area that is deemed to be of biodiversity importance.

This Is About Survival

Beaches are not decorative features.

They are infrastructure.
They are economic engines.
They are storm barriers.
They are cultural heritage.
They are ecological systems.

Protect herbivores.
Protect reefs.
Protect seagrass.
Protect sand.

Or watch our beaches disappear — bucket by bucket, fish by fish, dredge by dredge.

For a small island nation, this is not optional.

It is existential.

Are beaches really important to A&B?

Tourism and specifically coastal beach tourism is responsible for over 60% of Antigua and Barbuda's Gross Domestic Product (GDP) and it often seems that as a nation we are careless or complacent with what the industry relies upon. Wonderful beaches are what has built this economy and are what we as citizens boast about whenever we travel. That being said, our beaches have seen shocking degradation over the past few decades, and it appears to me that they are deteriorating at much more rapid rate than they are being replenished. In fact, that's fairly obvious to anyone who's being paying attention.
As is the case with so many crucially important things in life, "attention" is the thing lacking and unfortunately while beaches are getting smaller and smaller Antigua and Barbuda as a nation isn't taking notice.
I suppose before we can deal with the problem or even before we can identify a problem, we need to understand what a beach is, how it came to be and most importantly, how it is sustained in it's natural environment.
When we speak about beaches, we are speaking about bays, coves or shorelines that have a sandy buffer between the sea and the land. Sand is made up of different materials depending on where in the world you find it. In many areas in North America the sand is made up of silica or silicon dioxide which essentially comes from eroded quartz rock. Here in Antigua and Barbuda and most of the Caribbean the sand has a different makeup. Primarily sand here is made up of eroded or crushed up corals and shells which really are made from calcium carbonate. This is why islands like Barbuda that have more reefs usually have more beaches and islands like Redonda that have no off shore or barrier reefs have no sandy beaches. So if you think about it, there is an essential and direct correlation between a healthy reef system and a healthy beach system. Of course we are speaking about how these things naturally occur. For example, one could build some stone groynes to make a cove over on Redonda and barge in mined sand from Barbuda to fill it with. Presto! You have a nice sandy beach on an island that never had one. That is done around the Caribbean and quite a bit on Long Island (Jumby Bay).
I guess we could spend plenty of time speaking about what healthy reefs look like and to be honest, most people don't remember or have never seen a healthy reef. Reefs in the Caribbean haven't been "healthy" since the late 1980s. Since then scientists have reported unprecedented degradation and die offs. For the purpose of this little article I will quickly and basically explain about how healthy reefs produce sand. A reef is made up of millions and millions of organisms and the main coral structures are made from calcium carbonate. These structures, when alive, are often challenged by different types of algae (a type of moss) that attempt to grow on them. If algae is permitted to grow over the coral stuctures then the life sustaining sunlight is blocked from the coral polyps. Polyps are living organisms which often produce the limestone structures we call corals. They need light to survive and when algae manages to grow over them, they perish. For millions of years polyps have had the upper hand thanks to a symbiotic relationship with herbivore grazers like parrotfish (chub fish), surgeon fish and other marine species including urchins. Those critically important parrotfish feed on the algae keeping the reef alive, but the magic is what happens as a result. When parrotfish chew algae from a section of coral they usually bite of bits of dead coral. Most of the time they ingest it and pass it through their systems as they digest the algae. What comes out is magical "white gold" or sand. Some of the most important poo in the world in fact! That poo as I mentioned contains the sand which is  essentially responsible for about 60% of our GDP. I know that is kinda far fetched for most people who are probably laughing and shaking their heads right now, but do some reading on what parrotfish do. According to scientists, one adult parrotfish can produce 90 kilos of sand a year while keeping the reefs clean from algae. A healthy reef is covered in parrotfish and other algae eating animals which for millions of years not only sustained the reefs but produced millions of tonnes of sand. Take them away from the reef and anyone can deduce what happens next. However, you would have needed to be paying attention to have noticed all these crucially important relationships. We here in Antigua and Barbuda were not paying attention. In fact, the biggest seafood export out of Antigua and Barbuda over the past five years has been parrotfish. It has probably been our biggest export. Thousands of pounds a week of netted parrotfish were brought ashore to be sold both here and shipped abroad to our French neighbors. Pause and think about that for a moment. We rely on healthy beaches which rely on healthy reefs which rely on healthy populations of parrotfish and other herbivore species, but we are wiping the reefs clean of the parrotfish.
I remember being on a radio show with Chief Environmental Officer, Dianne Black Lane a few years ago and she remarking that the most important wild life form we have in our country is the parrotfish and one that needed to be protected more than any other. Sadly, the Environment Division she heads has no more legislative powers than the parrotfish themselves.
Coupled with out of control reef fishing, the reefs have also had to face several incredibly strong hurricanes in the 1990s. Scientists showed that reefs hit by hurricanes within carefully managed marine parks were able to "bounce back" to a point where healthy coral regrowth occurred. Of course, reefs that had poor management and where heavy fishing still took place struggled to stay alive, and in example after example the corals died out completely.
This brings me to another key factor that helps keep beaches healthy. Of course, we've already spoken about how the sand is created and how that process keeps reefs healthy, but by extension, healthy reefs often form an essential barrier or buffer from the Atlantic Ocean's waves and surges. We have seen areas of reef that boats couldn't navigate through because of depth issues become so degraded that they are now safely navigable. Kettle Bottom Shoal on Antigua's north coast is a great example of that. With the reef now deeper than it was back in the 80s we are seeing more surge and more wave action getting to beaches like Dutchmans Bay and Jabbawock. Climate Change effects like rising sea levels are not helping either! With more wave action there is often more erosion on beaches. Unfortunately these beaches are not being sustained with new fresh sand like they have been historically because of the depletion of parrotfish and other herbivore fish.
That isn't the end of the story because as if beaches didn't have enough to worry about, they have their biggest assault on the land side. Beach sand has been used when making concrete for generations and with more and more homes being built from concrete and fewer from wood, it appears to me that there is more and more removal of sand from beaches. There are few beaches in Antigua that are safe from sand mining and those that have easy access from the road are more susceptible to the problem. There is a common misconception that it is perfectly legal to remove a bucket or two from the beach. I am not sure how this terribly damaging concept came about, but many popular beaches have buckets of sand removed daily from them. I started a mobile kitesurfing school on Jabbawock beach in 2001 and we have seen this first hand since then. Thousands and thousands of bucket loads are taken from this beach and the same happens around the island. Often times there is more taken than a bucket or two at a time removed. If you take a slow walk along Jabbawock Beach you will see the trenches and holes where sand is scraped up into containers almost daily. It is beyond me how people think this wont have a negative affect on the beach.... our most important asset.
Yesterday I received calls about a misguided citizen who decided that he would do what he described as a community service down at Jabbawock beach. The beach has been receiving plenty of Atlantic sargasso seaweed recently and as an excavator owner he took it upon himself to ignore the massive sign about nesting sea turtles, about not driving on the beach or removing sand. He had two of his massive excavators go on to the beach and clear the live shoreline vegetation up to twenty meters from the high water mark up and down a 300 meter secton of beach. The scaevola, green button mangrove, sea grape, grasses and other vegetation not only provide crucial nesting cover for critically endangered sea turtles and other coastal marine species including migratory birds, but they also help prevent erosion by holding sand together in their root systems and foliage. In many countries it is illegal to touch coastal vegetation with stiff fines for even walking on sand dune vegetation. Yesterday all of this was destroyed and leveled on the South end of Jabbawock. The excavators operated under the cover of darkness and clumsily cleared small trees and habitat up and down the beach. They stopped in the morning. Several concerned citizens including myself contacted the various authorities in an attempt to make sure the excavators were moved from the beach and that work would be stopped. I was interviewed by Observer Radio about the situation before lunch explaining what was going down and further explaining that the 1980s environmental legislation isn't strong enough to deal with situations like this. The Environmental Management Bill, drafted by government technicians after help from international consultants and consultations with stakeholders, has been finished and has been sitting on various ministers desks for years and years. The government's inaction to get this bill signed into law is indirectly causing huge environmental damage daily on this little twin island state. One can only ponder why they have not gotten in passed into law. Anyway, despite this interview and all the calls to the relevant authorities, the man doing the excavation work called into a local radio talk show to explain himself. According to him he was "cleaning the seaweed" from the shore where he and many other swim. At 2 pm he continued to say he was returning to the beach to do more work. By the time we got back to the beach, he was at it again tearing up wonderfully healthy beach vegetation and leveling the beach by removing the dunes.
How could all of the various government agencies including the police know of the situation and not do anything to stop further destruction. It really showed just how flawed our system is and how little we actually care for the health of our beaches. We here in Antigua and Barbuda seem to have our heads in the sand figuratively while literally the sand vanishes daily. Apart from paying more attention to our most important natural resource, we need the Environmental Managment Bill signed into law immediately before it's just too late.

An alternative to Sand Mining in Barbuda.

Light tackle and deep sea sport fishing could be one of the main ways that the residents of Barbuda make a living after sand mining is finally put to rest. The destructive and irrational practice of large scale sand mining has been one of the main income generators of our sister island for decades, and despite engineers' and environmental consultants' best advice to stop, government has continued to sanction the lucrative yet unhealthy practice. 
Barbuda is one of the most beautiful islands in the Caribbean with dazzling white sand beaches stretching around most of it's deserted coastline. Approximately half of the coast is protected by barrier reef, and it's this reef which has helped to produce most of the island's wonderful sand. For millions of years parrot fish have chewed algae from coral which they easily digest. The bit's of chewed coral which are not digested are excreted as sand onto the sea floor. This essential process for Caribbean white sand production has made Barbuda one of the most attractive beach destinations in the region. One of the island's beaches is about the longest in the Caribbean, and at different times of the year tiny pink shells wash up on the shore turning the beach pink. There's nothing quite like it to be honest.
With all of this in mind it's hard to accept that commercial mining of this amazing sand has gone on without noticeable regulation for decades. It's to the point now that serious environmental issues are threatening the island's water supply and more critically the integrity of the coastline. We are starting to see erosion on some areas of shoreline closest to the mining. Some environmentalists think that the damage being done is so severe that it would take hundreds if not thousands of years for it to be corrected. Coupled with that has been a huge increase in the amount of parrot fish caught for export to Guadeloupe. Neither practice sustainable in any way and equally destructive for the beaches.
It would seem that mining the very thing that makes the island a sought after destination would be a bad decision, but the decision makers can't seem to find an alternative income generator. I can see why this has been difficult. Tourism in Barbuda has always lagged behind Antigua mainly because of transportation.
Without a large airport, there simply has never been enough seats coming to Barbuda to fill guest houses and hotels in any meaningful way. Tourism and all of the fun things that go along with tourism like sport fishing for example, have had it tough forcing the government to keep the mining of sand going. This could all change in the near future if decision makers are brave enough to entertain alternative business plans.
One of several changes that could happen has to do with Cruise Tourism. Many of the ships visiting some of the Caribbean's most celebrated destinations anchor off shore and tender their guests to little docks on the main land. Without any significant investment this could happen in Barbuda almost immediately. One or two small ships a week could provide significantly more employment than the entire mining industry does in Barbuda. In addition to that, the types of jobs generated would be ideal for Barbuda's residents who would be able to conduct both light tackle and off shore fishing opportunities. Barbuda has all of the top game fish species endemic to it's coastline and interior lagoon. Species like bonefish, tarpon, permit, barracuda, jacks, mackerel, wahoo, dolphin fish, tuna, marlin, sailfish and many others are not difficult to find for Barbuda's experienced fishers. Of course there is great diving, snorkeling and bird watching too. The island is a nature lovers dream come true, and there is no end to the excursion activities that could be designed to make cruise passengers happy. From an environemtal point of view, cruise tourism as an alternative to commercial sand mining is a no brainer. Limited capital investment would be needed to get a foot in the door and with all visitors coming to the island by tender there would be very little waste of any sort left by ships. They would not leave anything on the island except footprints and money. The potential to make Barbuda the main sport fishing destination in the eastern Caribbean is there and just waiting for the first ship to drop anchor. Until that happens white sand is still being exported to Antigua and other destinations to be irrationally used in construction.
