Much of Australia is covered by desert and Australians aren’t willing to simply accept it.

At one point, they decided to plant trees across these barren lands. Millions of dollars were spent and nearly a billion plants were planted.

At first, the attempt to bring the desert back to life seemed successful, but no one had accounted for a hidden threat that was capable of wiping out the new vegetation.

As a result, huge numbers of the newly planted trees began to die. And the problem of desertification only got worse.

But the Australians didn’t stop there. Next, they decided to fight the desert with the help of marine animals, creatures that seem completely unsuited to Australia’s harsh inland climate.

Yet, Australians went ahead with the idea. And here’s how it all worked out. To understand the scale of the disaster, we need to go back millions of years.

Back then, much of the Australian continent lay beneath the water, covered by shallow inland seas.

As geological processes reshaped the landscape and the water receded, enormous deposits of marine salt were left behind on land.

Over the thousands of years that followed, powerful ocean winds continuously carried microscopic particles of salty dust across the continent.

At the same time, around half of Australia’s rivers drained toward the interior, carrying salt inland rather than out to the ocean.

Add Australia’s dry climate, which causes water to evaporate rapidly. As a result, billions of tons of salt gradually settled into the soil and accumulated deep underground.

Above these salt-rich layers, a thick layer of dry soil formed, supporting the development of Australia’s unique native vegetation.

And for thousands of years, this enormous mass of salt remained safely locked away deep underground, waiting for something to set it in motion.

Eventually, that trigger came. By the late 19th century, European settlers had begun clearing vast areas of land for agriculture.

As part of government-backed settlement programs, more than 44 million acres of native woodland were cleared.

Much of the destruction affected Mali eucalypse, unusual trees with multiple stems that grow from large woody underground structures.

Their root systems could extend 65 to 100 ft below the surface, reaching deep into the soil and tapping underground water.

Essentially, the trees acted like powerful biological pumps. They continuously absorbed rain water as it filtered into the ground and released it back into the atmosphere through their leaves, helping keep the groundwater table safely below the salt-rich layers underground.

But when the native vegetation was replaced with wheat fields, this natural water balance broke down.

The new crops had much shallower roots and simply couldn’t absorb anywhere near as much water as the eucalyptus trees had.

As a result, more rain water began draining deep underground. Groundwater reserves rapidly increased and in some areas the water table began rising by as much as 3.3 feet a year.

Eventually, this rising groundwater reached ancient salt deposits deep underground, dissolved the salt, and became highly concentrated brine.

As the salty groundwater approached the surface, the soil began acting like a sponge, drawing the moisture upward through countless tiny pores.

Under the scorching sun, the water quickly evaporated, leaving behind the thick crust of salt.

The scale of the damage was catastrophic. More than 14 million acres of highly productive farmland were turned into barren white landscapes where crops could no longer survive.

But the crisis soon spread far beyond agriculture. The rising saline groundwater reached towns and cities.

Concentrated brine saturated the soil beneath developed areas and began damaging buildings and infrastructure from below.

High concentrations of salt accelerated the corrosion of steel reinforcement with concrete foundations. Sailing groundwater damaged concrete bridge supports, caused road surfaces to swell and weaken, and attacked underground utilities and pipelines.

Salinity had become a serious economic threat, and Australia now needed a way to bring the problem under control.

In 1989, the Australian government officially launched the 1 billion trees program, a nationwide initiative worth tens of millions of dollars.

The government gave environmental experts a clear target. Plant 1 billion trees on degraded land within exactly 10 years.

Create a continuous green barrier and get these natural biops drawing salty groundwater back out of the soil.

Heavy industrial machinery was brought onto the salt damaged land. Powerful bulldozers worked around the clock, ripping through the hardened ground and breaking up compacted saline layers.

The 1 billion tree target was reached ahead of schedule by the end of the 1990s.

Across Australia’s wheat belt, thousands of miles of new multi-row shelter belts reached across the landscape.

In some areas, the newly planted forest really did slow the rise of saline groundwater and lower the water table by 3 to 6 f feet.

The tree roots also stabilized the top soil, dramatically reducing destructive wind erosion and the washing away of salt affected soil.

The shelter belts also acted as barriers against hot, drying winds from the interior, creating a milder microclimate around them and protecting nearby farmland.

Though things didn’t go nearly as well as planned. After years of water logging, the upper layers of soil had accumulated enormous amounts of salt.

In many places, concentrations had crossed the threshold beyond which almost no ordinary plant could survive.

Normally, roots work like sponges, easily drawing water from the soil. But because the salt concentration had become so extreme, the soil was actually saltier than the fluids inside the plants, causing the ground to literally pull moisture out of the seedlings roots.

Young trees could be standing in wet soil and still die from severe dehydration. During the very first season, more than 80% of the eucalyptus and acacia seedlings died in the worst saltaffected areas.

Australia needed a different way to bring these lands back to life. And eventually, it found one.

Along the edges of fields devastated by salinity, drilling crews began sinking hundreds of wells roughly 100 to 165 ft deep and installing powerful submersible pumps.

The pumps began removing underground brine on a massive scale, artificially lowering groundwater levels and preventing salty water from rising toward the fertile top soil.

This slowed the spread of salinity and protected neighboring farmland from becoming completely barren. But that created another problem.

What could they do with all the salty water being pumped out of the ground?

Dumping it into local rivers wasn’t an option. That could have destroyed some of the region’s remaining freshwater supplies.

Instead, heavy machinery began digging evaporation ponds deep in the Australian interior. Some were large reservoirs, others much smaller, and some were a little more than shallow basins.

To keep the Seline water from seeping back into underground aquifers, the bottoms of the ponds were lined with dense synthetic membranes.

Scientists then analyzed the groundwater being pumped into these basins. The results shocked everybody. Chemically, the brine was remarkably similar to water from the Pacific Ocean.

That led researchers to propose an idea that initially sounded almost absurd. Turn these artificial desert lakes into habitats for marine animals.

They decided to introduce valuable saltwater species such as baramundi and silver jewish into the sunbaked evaporation ponds.

There was one major problem. All of these animals had to somehow be transported into the middle of the desert.

The delicate fish and other aquatic animals had to be carried by truck across the scorching outback where temperatures in direct sunlight could rise above 113 degrees Fahrenheit.

The journey could take around 20 hours without stopping. A specialized fleet of tanker trucks was prepared for the trip.

Each vehicle was equipped with liquid oxygen tank, simmonia filters, and refrigeration systems that kept the water at about 72° F despite the extreme heat outside.

Any long stop or failure of the cooling system could have killed an entire shipment through heat shock.

But the logistics worked and millions of animals were transported successfully. Yet after the fish were released into the ponds, mass dieoffs still began.

Scientists ran tests and quickly discovered the hidden cause. The underground saline water was critically deficient in one essential element, potassium.

Without enough potassium, the fish could no longer properly regulate the balance of water and salts inside their bodies.

In a desperate attempt to survive, their bodies began drawing potassium out of their own muscle tissue.

The muscles rapidly deteriorated and the fish died even though they were surrounded by water.

Engineers came up with a simple solution. They added inexpensive potassium chloride to the ponds by the ton.

The mineral balance of the water was artificially adjusted until it more closely resembled seawater.

And from that point on, the system finally began to work. The shallow outdoor ponds exposed to intense desert sunlight stayed within an almost ideal temperature range of 77 to 82° F for much of the year.

For warm water bear Monday, those conditions were nearly perfect. Their metabolism accelerated, allowing them to feed almost constantly without using much energy to maintain body temperature.

As a result, the fish could reach market size in only 8 months instead of 14.

Growth rates were reportedly 30 to 40% higher than on conventional marine farms. Today, Australia produces thousands of tons of premium fish every year in inland aquaculture facilities far from the ocean.

Major producers have built highly sophisticated fish farms in dry inland regions. From there, fresh baramundi can be shipped to restaurants in Sydney and Melbourne within hours of harvest.

More than half of the fish sold on Australia’s domestic market is now farmed rather than caught in the wild, including fish raised at inland facilities.

But fish alone weren’t enough. Australians started wondering if these sailing desert ponds could support baramundi.

Why not raise giant tiger prawns in them as well? So they tried it and almost immediately another problem appeared.

During molting, large numbers of prawns died or simply ate their vulnerable tankmates. Biochemists ran tests and quickly identified the cause.

The underground water was severely deficient in magnesium, which meant the prawns soft new shells couldn’t harden properly.

So the Australians returned to a method that had already worked. Add whatever was missing.

They began adding measured doses of cheap magnesium salts to the ponds. The problem vanished almost overnight.

The prawns began growing twice as fast as their ocean dwelling counterparts, developing rapidly without showing signs of disease.

Next, tiny brine shrimp known as artia were introduced into the artificial ecosystem. These remarkable organisms can live and reproduce in extremely salty water that would kill most other animals.

Once their populations expanded, farmers began taking advantage of another useful feature of artia. Their enormous numbers provided a natural source of live feed for baramunde and tiger prawns.

More importantly, once established in the ponds, the artia began acting as a powerful natural bofilter.

They filtered suspended organic matter from the water around the clock. Fish waste, bacterial buildup, and tiny particles of uneaten feed.

As they cleaned the water, the crustaceians also converted this organic waste into valuable protein rich in amino acids and fatty acids.

The system now delivered two benefits at once. Continuous biological filtration of the ponds and a self-renewing food source, forming a partially closed food chain in the middle of Australia’s red desert.

In the end, the industry itself is helping bring the Australian desert back to life.

And not just through the fish and other marine species it produces. Millions of fish and shrimp raised in these ponds produce enormous amounts of organic waste every day.

As a result, what was once lifeless, toxic underground brine effectively turns into a kind of fertilizer.

The Australians began using this nutrient-rich water to irrigate halifites, unique plants capable of thriving in extremely salty soils.

The first line of filtration was Salicornia, also known in the culinary world as sea asparagus.

Irrigated with waste water from the fish farm, Salicornia proved to be an extremely effective biological filter.

Its root system eagerly absorbs dissolved nitrogen and phosphorus, dramatically reducing the amount of organic pollution in the water.

Once most of the organic matter had been removed, the water was still salty, so it was sent farther down the line to irrigate plantations of old man’s salt bush.

This hearty shrub sends powerful roots 16 to 26 feet into the ground, prevents soil erosion, and easily tolerates extremely high salt concentrations.

In the end, this plant became a genuine lifeline for the local agricultural economy. It produces lush proteinrich forage, even during droughts when temperatures reach 122° F.

Thanks to these plantations, farmers were able to bring flocks numbering in the thousands back onto former salt flats for the first time in half a century.

And that’s when the project began producing an unexpected economic payoff. Sheep that regularly grazed on salt bush began producing a distinctive product known as salt bush lamb.

The meat is known for being juicy, relatively lean, and subtly salty and aromatic. Qualities that have made it highly sought after by top chefs.

Farmers who’d lost their livelihoods to salinity were able to switch to a completely new form of agriculture.

In the end, this entire chain produced a profound environmental effect. Constant pumping of underground brine lowered the groundwater table by several feet, bringing it safely below the critical level.

Seasonal rains then gradually leeched the remaining salt from the upper layers of the soil.

On neighboring fields, ordinary meadow grasses, clover, and wild shrubs began growing again for the first time in 50 years.

Insects, birds, and small mammals returned to the dry landscape while once dead land was transformed into a self-sustaining oasis.

Australians have proved that even an ecological nightmare can be turned into an opportunity and they’ve taken the idea even further.

Australia did not limit itself to breeding creatures in saltwater. The country also brings the desert to life with the help of freshwater creatures.

One example is the large-scale commercial farming of the Australian freshwater crayfish known as the common yabby.

And one thing should be made clear right away. This remarkable species is a true survivor of the harsh Australian outback.

In the wild, during severe droughts, yabies burrow deep into damp mud and enter a state of dormcancy in which they can wait years for the range to return.

They can tolerate murky stagnant water, sudden temperature swings, and even moderately saline groundwater. Farmers quickly realized that this crayfish was perfectly suited to intensive farming and artificial ponds and water storage dams across the continent’s arid regions.

But the Australians soon ran into a serious problem. Gabies turned out to be extremely aggressive and relentless cannibals.

When too many were kept together, large adults would quickly devour smaller, defenseless crayfish when the younger animals were vulnerable during molting.

So, engineers came up with a highly effective solution. Large numbers of honeycomb-l like shelters were placed on the bottoms of the artificial ponds.

Creating this kind of underwater apartment complex gave virtually every crayfish its own secure hiding place.

As a result, cannibalism within the population dropped dramatically, while the survival rate of young crayfish increased several times over.

The yabies diet turned out to be remarkably simple and cost-effective. Yabies feed on bottom sediment, decaying vegetation, and microorganisms, effectively converting organic matter into a valuable proteinrich commercial product.

And in warm, sunheated water, yabies grow exceptionally fast. They can reach market size in as little as 6 months.

Naturally, Australia has turned what was once a simple country food into a delicacy. The crayfish is firm, snow white, juicy meat, has a delicate flavor, and is prized by chefs, in some cases, even more highly than many varieties of marine shrimp.

Today, farms in South Australia and New South Wales raise hundreds of tons of yabies every year.

The product is supplied to high-end restaurants in Melbourne and Sydney, and is also actively exported to Asian markets.

But keeping all these animals alive in the middle of the desert, takes a tremendous amount of energy.

And deep in the Australian outback, hundreds of miles from the main power grid, the ongoing cost of diesel fuel threatened to eat up the project’s entire profit margin.

So the engineers turned to the most abundant resource in the Australian desert, the blazing sun.

Right next to the reservoirs, they built self-contained groundmounted solar power stations. The arrays were connected directly to the pumps and air compressors that supply oxygen to the aquaculture tanks.

This made the entire operation completely independent of the power grid and extremely cheap to run on a day-to-day basis.

But the Australians also decided to use solar panels to tackle another major problem. Under the desert sun, with air temperatures soaring above 113° F, the artificial ponds were losing huge amounts of water every month.

Water levels were dropping rapidly while salt concentrations were climbing to dangerous levels, threatening the fish and shrimp.

To protect the ponds, Australian engineers covered them with floating solar arrays. The panels were mounted on durable floating pontoons right on the surface of the saline water.

The solution delivered a major double benefit. First, the floating solar panels acted like a giant protective canopy.

They blocked direct sunlight from reaching much of the water surface, reducing evaporation of the valuable brine by 30% and saving hundreds of thousands of gallons of water.

Second, the panels benefited from natural water cooling. Conventional solar modules on land can become extremely hot, which significantly reduces their power output.

But here, the cooler body of water beneath the floating panels continuously carried away excess heat, keeping the solar cells cooler and allowing them to operate more efficiently.

As a result, the floating solar panels operated at 15% higher efficiency than comparable panels installed on land.

The engineers also use the excess electricity generated during the day to continuously pump water into storage reservoirs, keeping the system running through the night.

And these desert pools filled with marine life offer benefits beyond simply putting salty water to good use and bringing the desert back to life.

Traditional marine aquaculture comes with enormous risks. Fish farms in the open ocean routinely suffer heavy losses from disease outbreaks, parasitic sea lice, dangerous bacteria and red tides, toxic algel blooms.

Australia’s desert farms, by contrast, found themselves protected by an almost perfect natural biocurity barrier.

No marine parasite, bacterium, or oceanborn virus can physically cross hundreds of miles of scorching red desert.

As a result, there’s much less need for antibiotics, growth stimulants, hormones, or antifungal treatments on the farms.

On top of that, fish raised in the Australian desert can qualify for some of the world’s leading environmental and sustainability certifications.

Their flesh is free from microplastics, mercury, cadmium, and other heavy metals that contaminate many coastal areas around the world.

But the biggest environmental benefit of these desert fish farms may be the protection they offer the oceans.

Across parts of Asia and Latin America, millions of acres of vulnerable mangrove forests have been bulldozed to make way for shrimp farms.

Yet, mangroves are among the coast’s most important natural filters and carbon sinks, while also serving as vital nursery grounds for countless marine fish species.

The Australian approach completely avoids this kind of barbaric practice. All production facilities are built far inland in aid regions on barren or already degraded land hundreds of miles from the ocean.

At the same time, these projects help reduce pressure on wild fish stocks. Thousands of tons of clean farm-raised baramundi, silver jewish, and shrimp from the desert are supplied to the domestic market every day.

This significantly reduced the amount of fish that needed to be caught by large industrial trwers.

As a result, wild fishing populations along Australia’s continental shelf have been given a real chance to recover after decades of intensive commercial fishing.

Of course, Australia also exports its desert-raised fish and other seafood abroad, generating substantial revenue in the process.

But exports aren’t the only reason foreign money is flowing into the country. The success of the inland saline aquaculture concept quickly turned it into one of the most remarkable and important examples of marine aquaculture in the world.

Today, Australian engineering solutions, patents, and biochemical processes are being actively adopted by other countries with arid climates.

In the United Arab Emirates, Saudi Arabia, Qatar, and parts of Central Asia, for example, Australian specialists are helping build similar facilities from the ground up.

In places where salt flats and advancing deserts are destroying farmland and taking away people’s livelihoods, Australian technology is transforming barren dry wastelands into high-tech centers of food production and food security.

So, what can we take away from all of this? Australia’s original attempt to save its plains simply by planting trees failed because people were essentially trying to fight the laws of physics and chemistry.

But the Australians proved remarkably inventive. Instead of trying to force the salt back underground, they turned what had been a deadly threat into a valuable resource.

The creation of thriving marine ecosystems in the middle of a scorched red desert demonstrated that bold engineering, biochemistry, and a willingness to abandon conventional thinking can bring seemingly dead land back to life.

And yes, the Australians didn’t just save their land from degradation. They built a highly profitable industry and pioneered a new model for producing food in places where marine life was once thought impossible.
