Israel Stops Planting Trees and Introduces This Into the Desert— What Happened Next Was Unbelievable.

Look at this barren landscape. The surface is cracked. There is no visible water, and almost no life remains. This is Israel, and it faces a major geographical disadvantage. More than half of the country is covered by the Negev Desert. To solve the problem, Israel launched an enormous project — plant millions of trees directly in the desert. But the results were not what they expected. Those trees actually accelerated the degradation of the land. Even so, the Israelis did not give up. Instead of looking at the surface, they drilled deep underground and discovered something that could completely change the situation. By combining it with one small engineering detail, they transformed the entire system. So, what exactly did they find beneath the sand? Natural desert sand has a pale, light-colored surface. It works like a mirror, reflecting as much as 40% of incoming solar radiation back into space. Because of this, the desert heats up quickly during the day, but also releases that heat rapidly at night. However, 4 million Jerusalem pine trees completely disrupted this mechanism. Pine needles are dark green. Instead of reflecting sunlight, they absorb nearly all of the incoming solar radiation. The 11.6 square mile forest unintentionally became an enormous dark carpet, continuously absorbing heat and releasing it back into the atmosphere. Normally, trees can cool themselves by releasing water vapor through their leaves. But in an extremely dry environment like the Negev, the pine trees are forced to close their stomata in order to preserve the small amount of water remaining inside them. Their cooling mechanism collapses. Millions of trees begin trapping heat internally, their bark cracks, and they become perfect fuel for wildfires. Planting trees does not cool the desert. It creates an enormous heat retention system. Realizing that forcing nature to change on the surface was a scientific mistake, Dr. Yaron's research team decided to abandon the surface entirely. This time, they brought in large industrial drilling machines. The drill bit cut straight through layers of hot, dry rock and continued deep underground. And at a depth of more than 3,000 feet, or around 900 meters, the drill finally reached what they were looking for- an enormous underground water reserve formed during the Ice Age. Billions of cubic feet of water were hidden beneath the sand. But nature gives nothing away for free. This water was not a miracle. It carried extreme characteristics that immediately pushed Israeli experts into an enormous new challenge. During the 1970s, large industrial drilling machines were brought into the heart of the Negev desert. The drill bits penetrated the dry rock and reached depths of more than 3,000 feet, or around 900 meters below the surface. At that depth, they discovered an enormous quantity of water. This was an underground water reserve formed during the Ice Age. Billions of cubic feet of water had remained trapped beneath layers of rock for tens of thousands of years. Engineers activated powerful pumps to bring the first water to the surface. But when Yaron examined the samples in the laboratory, every hope of using the water directly for agriculture disappeared. The pumped water had a temperature of around 104 degrees Fahrenheit, or 40 degrees Celsius, because it had been heated by the Earth's crust. More importantly, it contained extremely high concentrations of salt and minerals. If this hot, saline water were applied directly to the ground, plant roots would be damaged almost immediately. As the water evaporated beneath the desert sun, it would leave behind a thick white crust of salt across the sand, making plant growth impossible. Engineers attempted to apply seawater filtration technology. Israel already had extensive expertise in water treatment. However, when this 104 degree Fahrenheit water with its high mineral concentration was pushed through filtration systems, the expensive membranes became clogged and damaged within only three weeks. The electricity required to pump water from 3,000 feet underground and run the filtration equipment made the system economically unsustainable. On top of that, disposing of the concentrated salt residue on the surface would severely contaminate the surrounding environment. The filtration approach was abandoned. Scientists were standing above an enormous water reserve, but its temperature and salinity made it destructive to plants. They needed a completely different strategy. If you had billions of cubic feet of hot, salty water, what would you do when high-tech machinery failed to solve the problem? The way the Israelis changed their approach next may be unlike anything found in a conventional agriculture textbook. Instead of trying to change the water to suit crops, researchers decided to find organisms that naturally thrive in warm, saline environments. They selected two high-value species, tropical tilapia and Australian barramundi. The salt, calcium, and magnesium composition of the Negev groundwater was highly suitable for raising these two fish species. Enormous enclosed facilities were built directly on the desert sand. The 104-degree Fahrenheit groundwater was pumped to the surface, passed through cooling towers to lower its temperature, and then sent directly into fish tanks. The critical feature of this system is that the water is constantly moving. Pumps create continuous flow inside the tanks. The current carries fish waste out toward the filtration system. Mechanical filters capture the larger particles. The water then passes through tanks containing beneficial bacteria. These bacteria break down the waste and clean the water before it is pumped back into the fish tanks. The naturally occurring salts in the groundwater help suppress harmful bacteria and parasites. The fish grow successfully without requiring antibiotics. Israel produces thousands of tons of clean fish, directly in the middle of the desert. However, even a recirculating system occasionally has to discharge part of its older water. This wastewater contains high levels of fish, manure, nitrogen, and phosphorus. The research team did not discard it. Instead, pipelines carried the wastewater away from the fish tanks and used drip irrigation to deliver it directly to the roots of salt-tolerant crops. They planted jojoba. This plant grows extremely well under high temperatures. Wastewater from the fish tanks helped accelerate its growth. Today, the Negev desert supplies around 50% of the jojoba oil used by the global cosmetics industry. Nearby, date palms are also irrigated with water from the fish facilities, producing unusually large fruit with high sugar content. The most surprising results came from the vineyards. Grapevines are extremely sensitive to soil conditions. When their roots encountered saline water from the fish system, the plants shifted into a survival mode. The vines sensed the difficult environment, reduced vegetative growth, and redirected more of their nutrients into the fruit. The grapes developed smaller berries with thicker skins to retain moisture. But the juice inside became exceptionally concentrated. These grapes were used to produce wine. Their flavor became so intense that Israeli desert wines went on to win awards in several quality competitions in France and Italy. Raising marine fish and producing wine in the middle of the desert, it sounds as though humans have completely controlled the environment. But can you guess the cost of maintaining this ecological system? Do not celebrate yet, because the biggest problem, energy, is only beginning. The groundwater used for fish farming helped develop part of the desert. But to expand agriculture further, Israel needed more water. So they turned to wastewater from urban areas. In many developed countries, only around 5-10% of domestic wastewater is recycled. In Israel, the rate is close to 90%. The Shafdan Wastewater Treatment Facility near Tel Aviv receives millions of gallons of municipal wastewater every day. The facility processes this water and converts it into a supply safe for agricultural use. Pumping stations then move the water through dozens of miles of pipelines directly into the Negev desert. More than half of the cotton fields and fruit orchards in the Negev now operate using this recycled water. However, pumping water from 3,000 feet underground, maintaining fish tank filtration systems, and transporting recycled water over long distances require enormous amounts of electricity. The Negev desert receives more than 300 sunny days every year. Engineers decided to use sunlight to power the entire system. They built the Ashalim Power Station. At the center of the facility stands a tower, 853 feet, or 260 meters, tall. Surrounding the tower are 50,000 mirrors. Each mirror is motorized and connected to a computer system. They automatically track the sun and reflect its light toward a single point at the top of the tower. Temperatures at the top of the tower can reach 930 degrees Fahrenheit, or 500 degrees Celsius. This heat warms specialized fluids inside the tower, producing high-pressure steam that drives electrical generators. To maintain power production at night, the facility uses molten salt storage tanks. The salt stores heat, collected during the day, allowing the generators to continue operating for hours after sunset. Beside the tower, Israel built large reservoirs containing recycled water. High temperatures cause water in these reservoirs to evaporate rapidly. To solve this problem, floating solar panels were installed directly on the surface. The panels cover the water and reduce evaporation. At the same time, the water beneath them helps cool the panels. On days when temperatures reach 122 degrees Fahrenheit, or 50 degrees Celsius, conventional solar panels can overheat and lose efficiency. The reservoir water keeps the floating panels cooler, allowing them to generate electricity closer to maximum performance. All of this technology is advanced and impressive, but can humans continue spending billions of US dollars and enormous amounts of energy to fight the desert forever? The real solution, the least expensive one, and potentially the most profitable, comes from an invisible organism beneath the sand. Have you ever heard of creating economic value from night-time dew? The pumping systems, solar towers, and fish farms deliver major results, but their construction and operating costs are extremely high. Dr. Yaron and researchers at the Volcani Institute continued searching for a farming method that would require far less electricity. They turned their attention to desert truffles. These fungi grow underground. They cannot produce their own energy from sunlight, and their root-like structures are not long enough to reach groundwater. To survive, desert truffles form a symbiotic relationship with a native shrub known as the rock rose plant. Scientists introduced desert truffle spores into the roots of young rock rose plants. They then planted these Rock rose can tolerate intense heat radiation and uses sunlight to produce carbohydrates. The plant transports these sugars down into its roots to feed the fungus. In return, the fungus develops an extremely fine network of filaments beneath the sand. During the day, the desert absorbs heat, while at night, temperatures drop sharply. This temperature difference causes moisture in the air to condense into tiny droplets of dew beneath the sand. The fungal network collects these droplets, along with minerals from the sand, and transfers them back toward the roots, supplying moisture to the plant. This system requires no high-powered pumps and no solar energy tower. Human intervention is limited to a drip irrigation system that provides only a small amount of water during the first few weeks while the plants establish their roots. After that, the growing process is almost entirely managed by nature. At harvest, desert truffles can sell for around $150 per kilogram, creating substantial economic value for local agriculture. Using biological characteristics to produce food in extreme environments is not limited to Israel. Several other countries are also developing similar systems. In South Australia, the Sundrop Farms complex operates in a barren desert, without relying on freshwater supplies or the conventional electrical grid. The facility uses a pipeline about 3.1 miles long to bring seawater inland. There, a solar tower standing 377 feet tall generates heat to desalinate seawater and produce electricity. Tomatoes are grown in coconut fiber substrate using the freshly desalinated water. Every year, the facility produces around 17,000 tons of tomatoes, accounting for about 15% of the Australian market. In the Sonoran Desert of Arizona in the United States, pumping stations bring saline groundwater to the surface to raise Pacific white shrimp. After each shrimp production cycle, the wastewater is reused to irrigate nearby cotton fields. In Xinjiang, China, a landlocked region located far from the ocean, engineers analyzed the composition of naturally occurring saline groundwater. They added minerals to create conditions similar to seawater. Inside these closed-tank systems, they have successfully raised shrimp, crabs, and salmon. In the United Arab Emirates, or UAE, an aquaculture complex was built near Dubai. Even when outdoor temperatures reach 113 degrees Fahrenheit, the cooling system keeps tank water at around 55 degrees Fahrenheit, or 12 degrees Celsius. The facility creates artificial currents and adjusts lighting to simulate a cold-water environment. As a result, it has successfully produced Atlantic salmon in the middle of the Middle Eastern Desert, reducing the need to transport frozen fish by air. From the unintended effects of 4 million pine trees, increasing heat absorption in the Negev, to salmon production systems operating in the deserts of Dubai, this development reflects a major change in the way humans interact with natural environments. Humanity once believed it could use machinery, labor, and enormous amounts of energy to transform desert surfaces into temperate forests. The result was often stressed vegetation systems and extremely high maintenance costs. Projects in Israel, Australia, the United States, and China demonstrate a different approach. A desert is not dead land. It operates according to its own physical laws and biological systems. When scientists stopped trying to transform 104-degree Fahrenheit saline groundwater into freshwater, and instead searched for aquatic species naturally suited to those conditions, they were able to establish efficient production models. When they reduced their dependence on high-powered pumps, and allowed truffle fungal networks to collect moisture naturally, they achieved high economic returns with far lower resource consumption. Technological development should not be measured only by the construction of enormous machines. The core factor is the ability to observe, collect accurate data about natural conditions, and then design production cycles that are compatible with the characteristics of the environment. That is how humans can maintain food supplies and sustain life even in some of the harshest regions on Earth. From solar-powered tomatoes in Australia and shrimp farms in the Arizona desert, to salmon raised near Dubai, which country do you think currently possesses the most advanced and efficient survival technology? Could deserts become one of humanity's major food-producing regions within the next few decades?
