Israel, Egypt, Saudi Arabia, and Namibia have implemented advanced engineering and water management strategies to overcome extreme desert climates. Through desalination, wastewater recycling, and precision irrigation, these nations have transformed barren landscapes into productive hubs for high-value crops, livestock, and medicinal plants.
Surrounded by intense armed conflict,
with more than 60% of its land covered
by desert and rainfall of just 20 millimeters per year,
Israel has nevertheless achieved a remarkable feat,
reaching an agricultural export value six times
the global average.
But how can a country with no major rivers
and extremely scarce freshwater become
a winter fruit and vegetable hub that feeds all of Europe?
The secret lies in its journey of squeezing freshwater
from the ocean, from seawater desalination
and brackish groundwater treatment
to reusing nearly 90% of its wastewater.
Today, join Agriculture Insight as we
uncover the secrets of turning seawater
into the lifeblood of Israel's agriculture.
It's all in this video.
Located on the Mediterranean coast
with bustling seaports such as Haifa, Ashdod, and Eilat,
Israel is strategically positioned
to become a supply hub for Europe's fruits and vegetables.
Thanks to its considerable trade advantages,
Israeli agricultural products reach ports
in Britain, France, and Germany after just a few days at sea,
even when farms on the old continent
are frozen over, affirming its position
as one of the world's leading exporters
of high-tech agricultural products.
Yet behind that glory lies an extraordinarily harsh struggle
for survival.
The arid desert climate makes natural freshwater here
scarcer and more expensive than ever.
In addition, rapid urbanization sharply
increases domestic water demand, forcing Israel
to solve a difficult problem, ensuring
water for millions of residents while maintaining
supplies for agriculture.
That pressure is compounded many times
over by a geopolitical cauldron perpetually
on the brink of erupting.
Amid fierce conflicts in the Gaza Strip
and tense military confrontations with Iran,
Israel cannot risk depending on external supplies
of food or resources.
With its survival hanging by a thread,
the drive to secure an independent water supply
has forced the country to achieve
something extraordinary, turning the ocean
into a source of life.
When freshwater is insufficient, Israel
does more than seek additional supplies.
It turns saline water sources into resources.
And that strategy follows two very different paths.
One source lies offshore in the Mediterranean Sea,
while the other is hidden deep beneath the parched soil
of the Negev and Arava desert regions.
The largest water source right before Israel's eyes
is something crops cannot drink, seawater.
Instead of surrendering to the intense salinity
of the Mediterranean, Israelis have
transformed the entire Western coastline
into a vast freshwater production zone.
Along the coast, large-scale desalination plants
draw in seawater, remove sand and impurities,
and then pass it through a membrane filtration system
under high pressure.
Put simply, this filtration layer
performs a critical task, retaining all the salt
while allowing water to pass through to the other side,
where it undergoes further treatment.
Yet there is an interesting paradox.
After filtration, the water is so clean
that it is actually lacking in nutrients,
with too little nourishment for crops to grow.
To solve this problem, Israeli engineers
add essential minerals back into the water,
turning the purified flow into a perfectly nourishing drink
that is pumped directly to vast fields.
Through this technological magic alone,
Israel has achieved self-sufficiency
in more than 80% of the domestic water supply
for its entire population.
More importantly, it frees up an enormous volume
of freshwater to flow directly into agriculture's lifeblood.
The intensely salty ocean, once a formidable barrier,
has now become an everlasting freshwater reserve,
helping Israel completely overcome its fear of drought.
Turning the ocean into a coastal freshwater source
is already a remarkable feat.
But what if the farms lie hundreds of kilometers inland,
deep in the desert?
Would Israelis really spend billions of dollars
laying pipelines to carry water inland
from the sea?
There is no need to look far.
The answer lies right beneath their feet.
Hundreds of meters beneath the scorching sands
of the Negev Desert,
Israelis have uncovered a forgotten treasure.
Vast oceans of brackish groundwater
once considered something no one wanted to use.
Brackish groundwater is a difficult resource to work with.
It is not fresh enough to drink,
yet it is not intensely salty like seawater either.
If used directly for irrigation,
the salt remaining in the water is still more than enough
to burn the roots of tender seedlings.
Instead of wasting this natural gift,
Israel has drilled deep into the desert,
bringing water trapped for millions of years to the surface.
Right on the farms,
they have installed compact filtration units
to reduce its salinity.
Because brackish groundwater has much lower salinity
than seawater,
the treatment process is considerably less demanding,
minimizing both costs and the energy needed to operate it.
By awakening the brackish groundwater
lying dormant beneath the desert,
Israel has not only solved the problem
of costly transportation,
but also turned seemingly useless water
into a secret weapon
that sustains major agricultural hubs
amid a barren wasteland.
Having gained control over water supplies
from the ocean and underground,
Israelis began sowing the seeds
of seemingly impossible agricultural achievements.
And the most striking example of this revolution
is the bell pepper.
What makes this remarkable
is that peppers are far from easy to grow.
Insufficient water quickly weakens the plants,
while excessive salinity can also impair their growth.
Israeli farmers have harnessed
that very same brackish groundwater
to achieve an impressive turnaround,
using a smart drip irrigation system
from precise down to the centimeter.
They mix the mildly saline water with nutrients
and deliver it directly to the roots,
wasting not a single drop.
But water alone is still not enough.
In the desert, Israelis must also tame the climate.
Right on stretches of barren sand that seemed useless,
they have painstakingly built rows
of sturdy greenhouses and net houses
covering a vast expanse of desert.
These structures create a perfect protective shield,
reducing hot winds, blocking the scorching sunlight,
and keeping temperatures inside stable.
The growing season is also carefully planned
so that most fruit production takes place
during the relatively mild winter months
in Southern Israel.
That slight natural salinity in the brackish water,
combined with the intense desert sunshine,
inadvertently acts like a vaccine,
stimulating the pepper plants
to push themselves to accumulate sugar.
Amid the arid Arava desert,
the greenhouses remain filled with rows of red,
yellow, and green peppers laden with fruit,
producing bell peppers that are not only plump and glossy
with satisfyingly crisp skins,
but also have a rich sweetness far exceeding that achieved
through traditional growing methods.
Then, when winter arrives and fresh vegetable supplies
fall sharply across many parts of Europe,
the greenhouses in Israel's desert remain bustling
with nonstop harvesting.
The harvested produce is quickly sorted, chilled,
and shipped to major markets such as Europe,
Russia, and North America,
cementing the unrivaled position of desert-grown produce
even during the coldest days.
While bell peppers must take shelter
in rows of modern greenhouses,
date palms are ready to face the desert sun head-on.
That confidence comes from roots
that reach deep into the ground
and an astonishing tolerance for salinity,
a challenge that would immediately defeat
most other fruit trees.
Drought tolerance does not mean
date palms need little water.
Commercial date plantations in Arava
depend almost entirely on irrigation
using the very same brackish groundwater
pumped from beneath the desert.
However, the salt in that water remains a double-edged sword.
If too much accumulates around the roots,
it can quickly devastate yields.
Israeli farmers therefore apply a special technique,
calculating an irrigation volume sufficient
both to supply the trees with moisture
and to flush excess salt out of the root zone.
Caring for the trees is already difficult,
but pollinating date palms
requires far more painstaking work.
Because date palms have separate male and female trees,
Israeli farmers cannot rely entirely on wind or insects.
They actively collect pollen from male trees
and apply it to female flower clusters by hand
or with specialized equipment.
As harvest season approaches,
the medjool bunches are also tied and covered
to reduce rubbing and damage and make harvesting easier.
That care is the key to producing consistent harvests
of plump medjool dates.
Arava and the Dead Sea region
have long been important date-growing areas in Israel,
with their produce sorted, packed,
and shipped to overseas markets.
Even more remarkably,
this fruit has an astonishingly long history.
Scientists have successfully germinated several date seeds
found at archeological sites in the Judean desert
that date back approximately 2,000 years.
This detail offers vivid proof
that date palms are far
from a newly emerging commercial crop,
but rather a plant that has been intertwined
with this land for thousands of years.
Not content with taming crops alone,
Israelis push the boundaries even further
by deciding to bring livestock into the heart of the desert.
Can you believe that a cow living in the desert,
where temperatures can scorch every living creature,
could produce twice as much milk
as cows living on lush green pastures?
That is the story of Israel's dairy cows.
Dairy cows are particularly sensitive to heat.
The hotter it gets, the less they eat,
the more readily their bodies expend energy,
the more stressed they become,
and the faster their milk production declines.
Yet under those very conditions,
Israel has a dairy herd whose average milk yield
ranks among the highest in the world.
The first secret lies in turning desert barns
into true cooling oases.
The barns are designed to be spacious and well-ventilated,
combining shade-providing roofs with rows of large fans.
Sprinkler systems wet the cows' bodies directly,
while strong airflow helps the water evaporate
and carry heat away.
Several times a day, this cycle of soaking
followed by fan cooling is repeated,
keeping conditions in the barns comfortable.
The water the cows drink is also strictly controlled.
Instead of giving them brackish desert groundwater,
Israelis supply them with fully desalinated water.
With pure freshwater to drink,
the cows drink more and consistently produce
up to 35 kilograms of milk per day,
far exceeding their output when drinking saline water.
This example shows that Israel's desalination technology
benefits not only crop farming,
but also livestock farming in the desert.
And to keep each cow highly productive,
farmers monitor them almost hourly.
Their rations combine forage, grains,
and appropriate sources of nutrients.
Meanwhile, on many modern farms,
sensors can record activity, time spent eating
and ruminating, and unusual changes.
If a cow starts eating less or shows signs of heat stress,
the manager can detect it early
instead of waiting until milk production drops noticeably.
The result is a surprisingly high figure
for a hot, water-scarce country.
In 2025, Israel's average production
exceeded 12,000 liters of milk per cow.
And national statistics continue to place Israel
highest among the countries
included in international comparisons.
But that success also brings the water challenge
into sharper focus than ever.
Crops need irrigation, cows need drinking water,
and barns need water for cooling.
So where does Israel get enough water
to sustain everything at once?
The answer does not lie solely
in creating new water supplies.
Israel also turns water that has already been used once
into a resource for its next use.
And that is where wastewater
begins its journey back to the fields.
In Israel, a drop of water leaving a bathroom or kitchen
has not necessarily reached the end of its life cycle.
Urban wastewater is collected and sent to treatment plants
where it undergoes multiple stages
to remove solids, organic matter, and pollutants.
Once it meets the appropriate standards,
instead of being discharged,
that water enters storage and distribution systems
to serve agriculture.
And to keep this recycling system
operating safely and smoothly,
the treatment plants, reservoirs,
and distribution pipelines themselves
must also be continually upgraded.
The combination of enormous scale and smart allocation
has made this remarkable achievement possible.
Nearly 90% of Israel's domestic wastewater is recycled,
meeting as much as half of the irrigation needs
of the country's entire agricultural sector.
By giving every drop of water a second life,
Israelis have put an advanced philosophy into practice,
delivering the right type of water to the right place.
Pure desalinated seawater is reserved
for urban domestic use,
while reclaimed water takes on the task
of nourishing the fields.
That precise allocation allows them
to make the most of every resource
without wasting a single precious drop of water.
But is this successful model truly perfect?
The truth is that behind these agricultural achievements
on sand lie hefty costs
that both people and nature must bear.
The greatest challenge comes
from the desalination plants themselves,
the heart of the nation's water supply.
The highly concentrated brine discharged back into the sea
is quietly forcing fish, shrimp, and coastal organisms
into a harsh struggle for survival.
On land, the challenge of protecting the soil
is no less formidable.
Continuous irrigation with brackish and recycled water
causes salts and residual trace substances
to gradually accumulate in the soil.
Like a double-edged sword, without strict control,
the very water that saves today's crops
risks hardening the soil
and eroding its fertility in the future.
Keeping the sands green
has therefore never been an absolute victory,
but an endless race to maintain a balance
between technological ambition
and the environment's capacity to endure.
Nourished by the Nile for more than 5,000 years,
Egypt, the cradle
of one of the world's greatest agricultural civilizations,
is gradually reaching the limits of its own survival.
The country's greatest paradox
is that it possesses
nearly one million square kilometers of territory,
roughly equivalent to the combined area
of France and Germany,
yet less than 4% of that land
is actually suitable for cultivation.
However, the problem is not simply the lack of farmland.
The problem is that it is almost impossible to expand.
While the population of this Muslim-majority nation
continues to grow by around one million people each year,
the amount of arable land has remained virtually unchanged,
an inevitable limitation.
Worse still, about 25,000 hectares of agricultural land
disappear every year due to urbanization.
As a result, nearly 60% of Egypt's food demand
depends on external supplies,
making the country one of the world's
largest wheat importers.
Not only is Egypt constrained by its harsh deserts,
but it also faces a critical vulnerability.
The entire nation depends almost entirely
on a single river.
Approximately 97% of Egypt's freshwater supply
comes from the Nile,
a river stretching more than 600 kilometers
across 11 countries.
Yet most of its flow originates from the Ethiopian highlands
where the Grand Ethiopian Renaissance Dam
has raised concerns about the future
of Egypt's water supply.
This means that the fate of more than 110 million people
depends on a river whose flow
is not entirely under their control.
While many see only hot, barren sand,
Egypt sees a vast reserve of untapped land.
If water can be delivered there,
these areas could become a strategic space
for absorbing population pressure,
expanding food production,
and strengthening national security.
As a result, Egypt began constructing
an unprecedented irrigation system,
collecting, treating, and redistributing
million cubic meters of water every day
to transform nearly one million hectares of the Sahara
into a new food-producing region for the 21st century.
However, this is not the first time
Egypt has attempted to turn the desert into farmland.
Decades ago, the country placed enormous hopes on Tashka,
a project celebrated as a miracle in the desert,
yet its actual results fell far short
of initial expectations.
So what makes Egypt believe that this time will be different?
And to understand how Egypt could create
a second Nile Delta in the heart of the Sahara,
we must begin with what seems like an impossible challenge.
Transporting millions of cubic meters of water
across the desert.
In 2021, the new Delta project was officially launched.
More than 12,000 workers and hundreds of heavy machines
operated almost around the clock,
transforming the area into a massive construction site
in the middle of a sea of sand.
The first step was stabilizing the terrain
as building on constantly shifting sand
presents a major challenge.
Across a landscape where sand continuously moves
under the influence of wind and temperature,
hundreds of bulldozers worked relentlessly
to level the ground, remove large sand dunes,
and reshape the entire desert surface.
Once the site had been prepared, canal excavation began.
The canal was designed to be about 45 meters wide
and seven meters deep, capable of transporting
enormous volumes of water using gravity alone.
At the same time, the accuracy of the entire route
was strictly controlled.
The longitudinal slope was adjusted with an error margin
of only about 2.5 centimeters per 30 meters,
a level of precision that is almost unimaginable
for a project stretching hundreds of kilometers.
Amid temperatures exceeding 50 degrees Celsius,
the entire construction site operated like a giant machine
constantly moving across an endless sea of sand.
Excavating the canal was only half the battle.
The bigger challenge was moving billions of liters of water
across more than 100 kilometers of desert
while minimizing losses along the way.
As a result, preventing water loss
became one of the most important objectives
of the entire project.
After the canal bed was stabilized,
a layer of fine sand approximately five centimeters thick
was evenly spread to create a cushioning surface
before 10 to 12 centimeter thick concrete slabs
were poured in standardized sections.
Between the concrete slabs, expansion joints were sealed
with hot bitumen to prevent leakage
and allow the structure to expand and contract
under the desert's extreme temperature fluctuations
where temperatures can range from around 10 degrees Celsius
at night to over 50 degrees Celsius during the day.
Upon completion, more than 124 kilometers of canal
had been reinforced and waterproofed,
creating one of the largest water conveyance systems
in North Africa.
Once the canal had been fully reinforced and waterproofed,
the next step was the art of flow control.
Along the canal route, intermediate regulating reservoirs
covering approximately two hectares each
were constructed to absorb flow fluctuations
and maintain a stable water supply.
But a giant canal alone could not support
nearly one million hectares of farmland.
Water still had to be delivered with precision
to fields scattered across the desert.
From the main canal, pipelines ranging from 1.5
to three meters in diameter are installed
to deliver water to new agricultural areas in the desert.
Most of the system is buried underground
to minimize evaporation losses,
while high-capacity pumping stations
and automated control systems
continuously regulate the flow,
ensuring a stable water supply throughout the region.
But what makes the new delta fundamentally different
from Tashka and many desert reclamation projects before it
is not the scale of the project.
It is the water behind it.
Most of the water comes from the agricultural drainage system
in the Nile Delta, where it is collected and treated
at massive facilities such as Al-Hammam
before being pumped back into the desert.
When the first control gates were opened,
water began flowing through the newly completed network
of canals and pipelines.
Every day, more than 7.5 million cubic meters of water
move through this system, making the new delta
one of the largest water redistribution networks
ever built in North Africa.
From this point forward,
Egypt is not simply bringing water into the desert.
It is recycling its entire irrigation system
to create a new food production engine for the 21st century.
As the first flows of water began moving
through the new network of canals and pipelines,
vast green oases gradually emerged
across the heart of the Sahara.
Spanning nearly 924,000 hectares of newly cultivated land,
these remote desert regions are becoming
one of the agricultural hubs contributing
more than 15 million tons
of agricultural products each year.
For many Egyptian farmers, this is the first time
they have watched the desert give way to green fields.
One of the new delta's most important objectives
is reducing Egypt's dependence on imported food.
Wheat, the country's staple crop,
sits at the center of that strategy.
Egypt still imports around 10 to 12 million tons
of wheat annually,
equivalent to nearly 60% of domestic consumption.
As harvest season arrives,
wheat fields stretching for dozens of kilometers
begin turning their characteristic golden color.
High-capacity combined harvesters operate continuously
to complete harvesting as quickly as possible,
minimizing losses under the desert's extreme temperatures.
Thanks to the vast new agricultural land in the Sahara,
the new delta has the potential to add approximately
one to two million tons of wheat production per year,
about four times the wheat output that Tashka once achieved.
But Egypt's history includes numerous desert projects
that failed because the soil quickly became salinized.
This raises a question even more important than production.
Can the new delta endure for decades?
Or is it merely a short-term success?
To avoid repeating the failures of the past,
new delta was designed not only to bring water
into the desert,
but also to control salt accumulation
through drainage systems and continuous soil monitoring.
In the long run,
the project's success will be determined
not by how much water is pumped in,
but by its ability to preserve soil fertility
for decades to come.
Egypt is not only trying to grow more food,
it is also trying to reduce billions of dollars
in agricultural imports.
With more than 3,000 hours of sunshine each year,
the hot, dry climate of northern Egypt
provides ideal conditions for sunflower cultivation.
Low humidity helps reduce pests and diseases,
while abundant sunlight increases
the oil content of the seeds.
Beyond supporting domestic cooking oil production,
sunflowers also help Egypt reduce its dependence
on imported vegetable oils.
Every year,
the country spends more than $1.5 billion
importing edible oils and oil seeds
to meet the needs of its population
of over 110 million people.
With average yields of around
two to three tons of seeds per hectare,
and oil content exceeding 40%,
each hectare of sunflowers can produce
nearly one ton of vegetable oil,
significantly higher than many traditional crops
under arid conditions.
This makes sunflowers an ideal choice
for the dry lands of the Sahara,
where every cubic meter of water
must generate the highest possible economic value.
While wheat sustains the population at home,
Egypt's legendary cotton is grown to compete
in some of the world's most premium textile markets.
In an industry dominated by massive producers
such as China, India, and the United States,
Egyptian cotton accounts for less than 1%
of global production.
What makes this cotton so special
is something that is almost impossible
to see with the naked eye.
Extra-long staple cotton varieties
possess fibers that are significantly longer
and stronger than those of conventional commercial cotton,
allowing the production of premium fabrics
renowned worldwide for their softness and durability.
But that quality also comes with strict requirements.
To preserve the fiber structure,
much of this premium cotton
must still be harvested carefully
to minimize damage during production.
Its exceptional value has also made premium cotton
one of the most counterfeited products in the world.
In 2016, Walmart, Target, and Bed Bath & Beyond
were even involved in a controversy
after selling products labeled 100% Egyptian cotton
that were later found to contain different types of cotton.
These controversies only further highlight
the unique value of the Egyptian cotton brand.
With cotton exports
generating more than half a billion dollars annually,
and the textile industry
contributing nearly $4 billion in revenue,
Egyptian cotton remains one of the most important pillars
of the country's economy.
Covering more than 2.1 million square kilometers,
Saudi Arabia is one of the largest countries
in the Middle East.
Yet more than 95% of its territory is desert,
forcing a population of more than 37 million people
to cluster along the coastlines of the Red Sea
and the Persian Gulf.
In many regions, the average annual rainfall
is less than 100 millimeters,
while summer temperatures regularly exceed
45 degrees Celsius.
Rivers are virtually non-existent,
surface water has almost disappeared,
and groundwater aquifers have been severely depleted
after decades of extraction.
This has left Saudi Arabia facing an unprecedented paradox.
The country possesses the resource
the entire world desires, oil.
But the one resource it lacks is water.
Despite sitting on more than 260 billion barrels of oil,
it still has to spend billions of dollars
just to produce every drop of freshwater.
In the Middle East, oil builds empires,
but water is what determines
which nations can survive in the long term.
That is why the country began developing
one of the largest water infrastructure systems
in the world, connecting giant coastal desalination plants
to a water pipeline network
stretching more than 12,000 kilometers,
more than twice the length of the Nile River,
forming a vast distribution system
that reaches deep into the interior.
More than just solving the challenge
of supplying drinking water,
this network has unlocked an even greater ambition,
transforming barren deserts
into industrial-scale agricultural regions
capable of producing millions of tons of food every year.
But to move water across thousands of kilometers
through one of the harshest deserts on earth,
Saudi Arabia first had to build rivers made of steel.
The journey that carries seawater across the desert
begins with a massive network of steel pipelines.
To withstand continuous high pumping pressure,
underground impact,
and the extreme heat of the desert,
these pipelines must meet
exceptionally demanding engineering standards.
That is why they are typically manufactured
from high-strength carbon steel,
the same material widely used in the oil and gas industry.
The process begins with enormous rectangular steel plates
pre-cut to precisely calculated dimensions.
Each plate is large enough that, once rolled,
it forms a pipe with a diameter of about 1.8 meters
and a wall thickness of nearly 25 millimeters.
The steel is then fed through a multi-roll forming machine.
Industrial rollers gradually press and bend the plate
until the flat sheet becomes a complete cylinder.
Once the two edges meet,
the pipe blank is ready for the most critical stage,
longitudinal seam welding.
Here, automated welding robots
travel along the entire length of the pipe,
creating a joint strong enough
to withstand continuous water pressure for many years.
After welding, the pipe is cooled with water,
precision ground to remove burrs
and correct dimensional deviations,
and then both ends are beveled to standard specifications,
allowing faster assembly, tighter connections,
and greater pressure resistance in the field.
At staging yards, every batch of pipes
is labeled and organized
according to the exact installation sequence
to prevent delays during field construction.
Each pipe section is typically about 12 meters long
and weighs up to 40 tons.
This length was not chosen at random.
It represents the optimal balance
between engineering requirements,
system reliability, transportation efficiency,
and installation along long distance routes
crossing the desert.
Even a single pipeline stretching 1,000 kilometers
requires more than 80,000 pipe sections,
turning logistics into a massive industrial operation.
Once every final coordinate has been confirmed,
an invisible road begins to emerge
across the heart of the desert.
First, the entire surface along the pipeline route
is leveled and widened into a corridor
about 40 meters across,
providing enough space for heavy machinery,
material storage areas, cranes,
and multiple construction crews to operate simultaneously.
Next, heavy excavators begin digging trenches
to the exact design elevation.
The trenches are typically two to three meters deep,
providing sufficient protection for the pipeline
against surface temperatures, vehicle loads,
and external environmental impacts.
But the desert is not made of sand alone.
Many areas consist of solid bedrock
or semi-mountainous terrain
where conventional excavator buckets are almost useless.
In these locations, construction crews must drill holes,
place industrial explosives,
and carry out controlled blasting in stages
to clear a path for the pipeline.
Once the trench is complete,
the sharp rocks and uneven ground
still cannot support the pipeline directly.
A bedding layer of fine sand or fine granular material
is first placed along the bottom of the trench,
creating a uniform cushion
that reduces localized pressure points
and minimizes stress on the pipeline
throughout decades of operation.
But even after the trench is ready,
the real challenge begins when 40-ton steel sections
must be lowered into position
with centimeter-level precision.
Each pipe section is positioned using cranes.
Before welding, a 360-degree hydraulic internal clamp
is inserted inside the pipe to align both ends perfectly
and maintain absolute concentricity.
Even the slightest misalignment can create flow turbulence.
Increased stress can shorten the service life
of the entire pipeline.
Once both pipe ends are secured,
the automated welding system
begins traveling around the circumference of the joint.
But speed means nothing if the weld is not flawless.
Every joint is therefore inspected
using industrial ultrasonic testing
to detect hidden cracks, internal voids,
or alignment defects that cannot be seen with the naked eye.
After inspection, the welded joint
is coated with multi-component epoxy
to restore the corrosion protection layer
for the decades ahead.
Only then do tracked side boom machines
move along the construction site,
lifting the entire steel assembly with wide slings
before lowering it into the trench centimeter by centimeter
to prevent bending or damage to the protective coating.
The final stage is multilayer backfilling.
Fine sand is placed first to protect the pipe surface,
after which soil and rock are added
and compacted layer by layer,
gradually burying the entire steel river
beneath the desert to ensure long-term stability for decades.
But at this point,
Saudi Arabia has only finished building the road.
It still has not created the water.
Everything begins with the vast,
seemingly endless blue ocean offshore.
Instead of drawing seawater close to the coastline
where sand, oil, plankton, and pollution
are more concentrated,
desalination plants typically place offshore intake systems
several hundred meters to a few kilometers from shore
in deeper, more stable waters.
Once inside the plant,
the seawater passes through two stages
of coarse and fine screening to remove all impurities,
from large debris to small marine organisms
and remaining organic matter
before entering the treatment system.
But the most dangerous contaminants are almost invisible.
To remove fine sand, silt, and suspended particles
that could damage pumps and filtration membranes,
the seawater passes through
a multilayer sand filtration system,
reducing turbidity from 5 to 20 NTU to less than 1 NTU.
Next, the water is treated with chemicals to disinfect it
and coagulate suspended particles
before passing through 1 to 5 micron cartridge filters,
the final protective barrier
for the expensive reverse osmosis membranes.
Then the water reaches the heart of the entire system,
reverse osmosis.
To separate salt from seawater,
Saudi Arabia uses high-pressure pumps
operating at 55 to 70 bar,
forcing water against its natural osmotic direction
through ultra-fine reverse osmosis membranes,
where only water molecules can pass
while salt, bacteria, and impurities are left behind.
Before entering the distribution system,
the water is remineralized
and its pH is adjusted to ensure chemical stability.
It is then produced continuously 24 hours a day,
seven days a week,
at a scale of nearly 16 billion liters per day,
making Saudi Arabia
one of the world's largest desalination producers.
For Saudi Arabia,
desalination has never been the final destination.
It is only the first step in transforming seawater
into green farmland
across one of the harshest deserts on earth.
Water from the massive pipeline network
is quickly delivered to the desert
to serve an even greater goal,
achieving food security.
Within just a few decades,
giant green oases spread across
more than 11,000 square kilometers of desert,
creating one of the world's largest
center pivot irrigation systems.
Throughout the growing season,
automated irrigation systems
continuously adjust the amount of water
according to the crops' needs
before combined harvesters
complete the entire harvesting process.
By the late 1980s,
Saudi Arabia was producing
more than four million tons of wheat
every year,
not only becoming fully self-sufficient
in domestic demand,
but also exporting wheat
to international markets.
However, this success
also led to the excessive depletion
of groundwater aquifers,
forcing the country to gradually end
its wheat self-sufficiency program
and shift toward cultivating higher value crops.
That was also the moment
when the precious water
flowing through the desert
was redirected to an agricultural industry
that has been part of Saudi Arabia
for thousands of years,
date palm cultivation.
As the driest country in sub-Saharan Africa,
Namibia is so vast and unforgiving
that even America's Death Valley,
if placed within it,
would appear as little more
than a small fragment
between two enormous deserts.
To the west lies the Namib,
the world's oldest desert,
famous for some of the tallest
red sand dunes on Earth,
stretching all the way
to the fog-shrouded shores
of the Skeleton Coast.
The cold Benguela current
flowing offshore creates powerful waves
and limited visibility,
capsizing ships and turning hundreds of them
into decaying wrecks.
For centuries, terrified sailors
referred to this place
as the gateway to hell.
To the east lies the Kalahari,
a vast semi-desert
covered with dry grasslands,
thorny shrubs,
and a few scattered water sources.
Beneath these scorching sands,
Namibia holds a treasure trove
of some of the world's
most valuable gem-quality diamonds.
Yet diamonds cannot quench thirst
or fill empty stomachs.
For much of the population,
agriculture remains the foundation
of their livelihoods.
Nearly 70% of Namibians
depend directly or indirectly
on livestock farming
and crop cultivation,
even though arable land
accounts for less than 1%
Namibian agriculture, therefore,
is not built upon fertile fields.
Instead, it revolves around
drought-resistant crops,
livestock herds grazing
across immense open spaces,
and the ultimate art of survival,
making use of every precious drop of water
in the heart of the desert.
It would not be an exaggeration to say
that Namibia's beef export industry
holds one of the most enviable
Thanks to its strict
animal disease control standards,
Namibia was not only
the first African country
to export beef to the United States,
but has also become a trusted supplier
capable of meeting
the stringent regulations
of the European Union
and the United Kingdom.
To explore this supply chain,
we travel to Namibia's central plateau,
where commercial cattle farms
stretch across vast areas of dry savanna.
A key foundation of the industry
is the veterinary cordon fence,
which separates different
animal disease control zones.
The area south of the fence
is internationally recognized
as free from foot and mouth disease
without vaccination,
allowing Namibian beef
to access high-value export markets.
On farms covering thousands of hectares,
heat-tolerant breeds such as
Bonsmara, Brahmin, and Afrikaner
are raised mainly through extensive grazing.
Each animal is identified
with an official ear tag,
while ownership records,
medical treatments, and movements
are managed through the Namli-T system.
During the rainy season,
cattle graze on natural savanna grasses.
When the dry season continues
and pasture quality declines,
farmers provide hay,
mineral supplements, grain,
or feed made from processed bush vegetation
to help the animals
maintain their condition.
Under fan meat standards,
growth hormones are prohibited,
while antibiotics may only be used
for treatment under veterinary guidance.
Cattle must complete
the required withdrawal period
before being sent to slaughter,
ensuring that the meat
does not contain residues
above permitted limits.
Once they reach the standard live weight
of between 450 and 500 kilograms,
the cattle are transported
to export-approved abattoirs.
There, ear tags, movement permits,
and the origin of each livestock consignment
are carefully verified
before the animals
enter the processing line.
The carcasses are chilled,
grated, and cut into portions
such as tenderloin, strip loin, and ribeye.
The products are then vacuum-packed,
stored either chilled or frozen,
and loaded into refrigerated containers
for shipment to international markets.
Amid rocky mountains, dry sand,
and extremely limited rainfall,
lush green rows of grapevines
stretch along the Orange River.
This is Ossentier,
where Namibia has turned
river water, abundant sunshine,
and a seasonal advantage
into a large-scale table grape industry.
Each vineyard is arranged in long,
perfectly straight rows of trellises.
After the harvest,
workers prune the vines
to control the number of shoots
for the following season.
As the vines grow,
young branches are tied to the trellises,
while the canopy is carefully managed
so that sunlight can reach
each cluster of grapes.
Growers also remove excess flowers
and undersized berries,
allowing the remaining nutrients
to concentrate on clusters
that can develop to a more uniform size.
Toward the end of the year,
the vineyards enter their busiest period.
Workers usually begin harvesting
early in the morning,
while temperatures are still low.
Each bunch is cut with specialized shears,
gently lifted by hand,
and placed into plastic trays
to prevent bruising.
The grapes grown here are mainly green,
red, or black seedless varieties
intended for fresh consumption
rather than wine production.
Immediately after leaving the vineyard,
the trays of grapes are quickly transported
to the packing facility.
Workers inspect each bunch,
removing damaged berries,
dry leaves, and excess stems.
Unlike many other fruits,
table grapes are generally not washed
with water before packing
because moisture can increase the risk of decay
and remove the natural waxy bloom
that protects the surface of the fruit.
Bunches that meet the required standards
are then sorted by variety,
color, size, and quality.
They are weighed precisely,
placed into bags or small containers,
and packed into ventilated cardboard boxes.
Each box carries a traceability code,
allowing buyers to identify the farm,
production lot, and packing date.
The grapes are then rapidly cooled
to remove field heat
and kept within an unbroken cold chain
throughout transportation.
Refrigerated containers leave Asenker
and travel hundreds of kilometers to the port
before being exported to Europe,
South Africa, and other markets.
Namibia's major advantage
is that its harvest begins in November
and continues until shortly before Christmas,
a period when the international supply of grapes
remains relatively limited.
During the 2024 to 2025 season,
Namibia exported approximately
60,775 tons of table grapes.
This single fruit accounted for around 64%
of the country's total horticultural exports,
making it the most important export product
in Namibia's crop-growing sector.
Leaving the vast vineyards behind,
we continue our journey to Devil's Claw,
a medicinal plant that grows wild
beneath the thick sands of the Kalahari Desert.
Despite its rough and thorny appearance,
this plant contains enormous medicinal value,
making Namibia the world's largest supplier
of Devil's Claw and meeting more than 90%
of the demand from Europe's pharmaceutical industry.
The name Devil's Claw comes
from an extraordinary feature of nature.
Its fruit resembles a wooden spider
covered with numerous sharp, curved hooks.
These hooks can become firmly embedded
in the feet or fur of livestock
or even in the tires of passing vehicles,
causing animals to carry
and unintentionally spread the seeds across the desert.
Hidden beneath the cluster of leaves
creeping close to the ground
is a system of secondary tubers
that stores nutrients and water.
To harvest them, local people, particularly the San,
must use small shovels to carefully dig deep
into the sun-scorched, dry sand.
They strictly follow an ecological rule.
Only the horizontal secondary tubers are cut and removed,
while the main tuber and taproot are always left intact
so that the plant can regenerate for future seasons.
Immediately after being dug up,
the Devil's Claw tubers are washed to remove the sand,
sliced into thin pieces,
and spread evenly on raised drying racks
under the intense sun.
The sunlight removes the moisture
and concentrates harpagicide,
a natural active compound
known for its anti-inflammatory properties
and its ability to relieve joint and back pain.
Once the slices reach the required level of dryness,
they are packed into sacks,
subjected to strict quality inspections,
and exported to countries such as Germany and France.
Remarkably, this multimillion-dollar medicinal plant
is extremely difficult to propagate or cultivate
on a large industrial scale.
Nearly the entire global supply
still depends on the manual harvesting work
of indigenous communities across the Kalahari Desert.
