The first thing you notice isn’t the heat.
It’s the green.
On the edge of Riyadh, where beige apartment blocks dissolve into open desert, long flatbed trucks crawl by, stacked high with trees wrapped in burlap. Young workers in dusty vests jump down, their faces shining with sweat, guiding palm after palm into pre-dug holes along a brand-new boulevard leading nowhere yet. The air smells of diesel, wet soil, and something else that feels almost unreal in this part of the world: a faint forest scent.
A few hundred kilometers away in Dubai, cranes swing over a waterfront park, hoses blast reclaimed water into trenches, and imported African and European saplings wait under shade cloths like fragile VIP guests.
This is what a climate strategy looks like when a desert turns into a mega-city, then realises it is getting too hot to breathe.
Desert nations racing to plant forests of shade
Saudi Arabia and the United Arab Emirates are now importing millions of trees every year, trying to cool cities that have exploded outward faster than the shade could follow. Wide highways, glass towers, and concrete villas have amplified the so‑called urban heat island, turning late afternoon walks into survival missions.
City planners, pressured by residents and global investors, are betting big on green. They talk about “climate resilience corridors” and “urban forests”, but on the ground it simply looks like rows of tired men digging holes in the sand, trying to plant a cooler future one sapling at a time.
Look at Riyadh’s King Salman Park project and you see the scale of the ambition. The park, still under construction, aims to become one of the largest urban parks on the planet, roughly the size of a small city in itself. Saudi officials claim the wider Saudi Green Initiative plans to plant 10 billion trees nationally in the coming decades.
In Dubai and Abu Dhabi, municipal nurseries are overflowing. Ships unload containers with seedlings from Spain, Italy, Kenya, and even Australia, chosen for their ability to cope with scorching sun and salty soils. A Dubai landscaping manager joked that his real job now is “traffic control for trees”, telling drivers where to dump the next batch of living cargo.
The logic is straightforward: more trees, more shade, less heat. Studies from Gulf universities show shaded streets can feel 5 to 10 degrees cooler than bare ones, and neighborhoods with dense canopy often record dramatically lower surface temperatures on satellite images.
There’s also a political layer. As Saudi Arabia pitches futuristic mega-projects like NEOM and The Line, images of green valleys between glass walls help soften global criticism about fossil fuels. The UAE, fresh from hosting COP28, uses shots of lush boulevards and new mangrove belts to brand itself as a climate-conscious hub. The trees are both climate tools and PR symbols, growing roots in the sand and in the global imagination at the same time.

The hidden cost of importing a forest into the desert
Planting a tree in the Arabian Peninsula isn’t like planting one in a rainy European suburb. Every sapling that arrives by sea or plane needs a small life-support system: drip irrigation, treated wastewater, and often a protective mesh against sand and wind. Landscape designers now talk more about pipe diameters and salinity tolerance than about aesthetics.
The method is highly engineered. Teams map out “cooling corridors” of trees along major roads and pedestrian routes, connecting parks, malls, and metro stations so people can move under shade as much as possible. It’s less about making cities pretty and more about making them survivable after 3 p.m. in August.
Residents are slowly learning the new rhythm of the green infrastructure. In Abu Dhabi, a Filipino delivery rider described how he now plans his route to follow streets lined with neem and ghaf trees, shaving a few degrees off a brutal shift. In Jeddah, parents time late-afternoon visits to new coastal parks, where fresh imports from foreign nurseries stand next to hardy local species, both fed by greywater from surrounding buildings.
Yet there are awkward moments. Some freshly planted boulevards look lush on government Instagram feeds but bone-dry in person, because irrigation lines haven’t caught up or budgets were delayed. Let’s be honest: nobody really checks on every sapling once the ribbon-cutting photos are done. Some wither quietly in the sand, a reminder that planting fast is easier than caring long-term.
The push for shade has sparked real debates in local planning circles. Why buy water-hungry, non-native species when the region already has resilient trees like ghaf or sidr that survived centuries of drought? Why chase an imported “European park” aesthetic in cities that get barely any rain?
Experts warn about groundwater depletion, energy use for desalination, and the risk of creating thirsty forests that can’t survive without constant pumping. *You can’t air-condition an entire country with leaves alone.* The emerging consensus is that trees only work when combined with cooler building materials, reflective roofs, shaded walkways, and fewer dark asphalt surfaces. Otherwise, they become green decoration on top of a very hot problem.
Between ambition and reality: how the Gulf is learning to green wisely
Behind the glossy renderings, there’s a quieter shift toward more practical, almost humble techniques. City engineers in Riyadh now design “tree pits” that harvest every drop of rare rain, letting water seep to the roots instead of disappearing into drains. Irrigation systems are being tied to sensors, dripping water only at night, when less evaporates into the open air.
On the UAE’s outskirts, trial plots mix imported species with native ones, watching which survive with less water and more wind. The real winners are often the unphotogenic local shrubs that don’t show well on brochures but handle August like pros.
Urban planners also admit something that rarely makes it into press releases: not every street needs to be green. Some areas are now zoned for dense canopy, others for lower vegetation and shaded structures that use less water. There’s a growing focus on cool bus stops, arcades, and covered walkways that work with or without trees.
Many residents feel torn. They love the new parks and tree-lined promenades, yet worry about the hidden water bill in a region already running on desalination plants. We’ve all been there, that moment when you step under a young tree’s shade, feel instant relief, then suddenly wonder what it costs to keep that little patch of comfort alive.
“Planting trees in the desert isn’t about copying Europe,” a landscape architect in Dubai told me. “It’s about designing shade that respects where we live. If the tree doesn’t make sense with our water, our soil, and our lifestyle, it’s just a very expensive decoration.”
- Choose hardy species first – Ghaf, sidr, date palm, and acacia handle heat, salt, and wind far better than delicate imports.
- Use treated wastewater – Both Saudi and UAE cities increasingly route recycled water to parks, medians, and street trees.
- Think shade, not just beauty – Branch shape, leaf density, and height matter more than flowers when the real goal is cooler streets.
- Cool the ground too – Lighter pavements, permeable surfaces, and narrow roads keep shaded areas from radiating heat back up.
- Plan for maintenance – A dead tree is worse than no tree: it wastes water, money, and trust in public climate projects.
What kind of future grows out of a million imported trees?
Saudi Arabia and the UAE are trying something audacious: rewriting the relationship between desert cities and the land that hosts them. Their mega-city expansions made life more modern, then more exhausting, and now they’re racing to soften that impact with green belts, shade tunnels, and vast urban parks that didn’t exist a decade ago.
There’s a tension at the heart of it all. These are oil-rich states funding tree imports and desalination-powered irrigation to cool the very urban lifestyles that fossil fuels helped create. Yet within that contradiction, you can also see a kind of laboratory for the rest of the hot, crowded world. Cities from Phoenix to New Delhi are watching how the Gulf experiments with water recycling, species selection, and the simple act of putting a tree exactly where a human needs it most.
The real test won’t be this year’s satellite photos or glossy climate pledges. It will be whether, 20 years from now, a child walking to school in Riyadh or Sharjah remembers their city as a place where the street itself was merciful. Where summer still burned, but someone, somewhere, had planned just enough shade for them to keep walking.

FAQ:
- Question 1Why are Saudi Arabia and the UAE importing so many trees instead of just planting local ones?Local species are part of the mix, but demand for fast, dense shade around new mega-projects has outpaced what regional nurseries can produce. Imported trees fill that gap while planners expand native plant programs.
- Question 2Does planting all these trees really cool the cities down?Shaded streets and parks can feel several degrees cooler, especially at pedestrian level. Trees don’t fix the climate crisis, but they can make daily life more bearable in brutal summer heat.
- Question 3Isn’t this strategy wasting precious water in the desert?That’s the main criticism. Cities are trying to limit the damage by using treated wastewater and drip irrigation, yet the water footprint is still significant and remains a hot topic in local debates.
- Question 4Which tree species are proving most successful in the Gulf mega-cities?Hardy species like ghaf, sidr, date palms, acacia, and some carefully selected imports with high heat and salt tolerance tend to survive best with less water and maintenance.
- Question 5Could other hot cities copy what Saudi and the UAE are doing?Yes, with adaptation. The core ideas—mix of shade trees, recycled water, cooler materials, and planning streets around comfort—are already inspiring policies in cities from southern Europe to North Africa.
