More Than 5 Million Native Plants Reintroduced In Deserts Are Slowing Land Degradation And Rebooting Arid Ecosystems

It just looks tired. On the cracked ground outside a village in Rajasthan, a boy in plastic sandals drags a hose towards a row of tiny green specks. His father kneels in the dust, fingers stained with damp soil, patting the roots of a baby shrub into place like you would tuck in a child. Around them, the land is the colour of old bone. But this narrow strip is different. It smells faintly of life.

They’re not alone. From the Sahara to the Sonoran Desert, from the drylands of Peru to the Arabian Peninsula, teams like this are planting native species by the million. Not lawns. Not ornamental trees. Tough, local plants built for heat and hunger. Satellites are already picking up the change: darker pixels where there used to be bare sand. The number that keeps coming back is staggering. More than five million native plants, quietly rebooting dry lands that many experts had written off. And that’s where the story starts to twist.

When deserts start to breathe again

The first thing you notice in a restored desert isn’t the plants. It’s the temperature. Step off a bare roadside into a patch of reintroduced native shrubs and grasses, and the air drops by a couple of degrees. A muted, almost shy kind of cool. Your boots sink a little into soil that suddenly has texture, not just dust.

Rewilders in northern Mexico describe this as “teaching the desert to breathe again”. Sparse rows of native mesquite, palo verde and saltbush slow the wind so it can’t rip the topsoil away. Their roots grab what little rain falls and hold it there a bit longer. Tiny insects show up first. Then lizards. Then, one day, a rabbit track crosses the sand between two saplings, and everyone on the team takes a photo like it’s a celebrity sighting.

Statistics feel cold next to a rabbit track. Yet the scale is part of what makes this wave of planting different. In the Sahel, Africa’s so‑called Great Green Wall has gone from grand idea to millions of real shrubs and trees in the ground. In just one reforestation belt in Niger, farmers have helped regenerate around 200 million native trees, nursing them back from stumps. Across drylands globally, recent UN‑backed projects report more than 5 million individual native plants reintroduced in just a few years.

Land degradation in dry areas can feel like an unstoppable slide: soil blown away, crops failing, people leaving. These planting projects interrupt that slide. One plot at a time, they slow erosion, cut wind speed, and gently cool down surface temperatures. In some monitored sites in China’s drylands, erosion rates fell by up to 60% once native shrubs took hold. It’s not a lush forest. It’s more like turning down the volume on a slow disaster.

Behind the numbers sits a simple ecological logic. Native desert plants are not “poor cousins” of forest trees. They’re specialists. Many grow deep taproots that drill several metres down, accessing moisture that imported species can’t reach. Others spread wide, forming living nets that trap sand and organic matter. As they stabilize the soil, microscopic fungi and bacteria move back in, followed by beetles that shred organic debris into something like crude compost.

That thin, darker layer is where the magic happens. It stores more carbon than bare sand and absorbs more rainfall before it runs off in flash floods. Over time, you get a feedback loop. Plants make soil. Soil holds water. Water allows more plants to survive. Life in these places will always be sparse by design, but **sparse** is very different from broken.

The quiet engineering behind five million plants

From the outside, it looks like “just planting trees”. On the ground, it’s closer to surgery. Successful desert restoration starts with a ruthless question: what used to grow here when this land still functioned? Teams dig into old records, talk to elders, and walk the land looking for stubborn survivors clinging to rocky gullies.

Once they have a shortlist of species, the real work begins. Seeds are collected from local plants to keep genetics adapted to that exact heat, wind and soil. In Morocco, for example, nurseries growing native argan, acacia and halophyte shrubs shade young plants with woven palm leaves, not plastic, to mimic filtered desert light. Seedlings are hardened outdoors, stressed on purpose so they learn small roots and low expectations.

The planting itself follows the water, not the calendar. Crews in Jordan start at the end of a rare rain, racing the evaporation. They use micro‑catchments: shallow half‑moon pits or V‑shaped basins carved into the slope, each cradling just one or two plants. This directs every stray drop and bit of dew to the roots. Mulch, often just dry grass or stones, protects the surface from baking. It looks almost laughably minimal. Yet survival rates can jump from under 10% to close to 60% with these low‑tech tricks.

Here’s the honest part nobody likes to put in glossy reports: a lot of plants still die. Go back after the first summer and you’ll find gaps like missing teeth. Some projects once treated that as failure. Now, the smarter teams treat it as data. Species that soldier through with no irrigation earn more space in the next planting round. Shallow‑rooted imports get quietly dropped. Soyons honnêtes : personne ne fait vraiment ça tous les jours, mais where communities stay involved year after year, the second and third rounds of planting are where landscapes actually begin to shift.

One project leader in southern Tunisia put it this way:

“We stopped asking, ‘How do we green the desert?’ and started asking, ‘How do we make it habitable for what already belongs here?’ That’s when things changed.”

From a distance, this can sound abstract or heroic. Up close, it’s a lot of ordinary people doing small, repeatable things. A herder agreeing to fence his goats out of a test plot for three years. A teacher taking students to water seedlings once a week. A village deciding that women, who often walk furthest for firewood, should help pick which native shrubs get priority.

Across projects, a few quiet patterns keep showing up:

  • Start small, then repeat: pilot plots before big campaigns.
  • Plant fewer species, but pick them with obsessive care.
  • Let local people own the decisions, not just the labour.

When those pieces line up, five million plants is not a photo op. It’s the beginning of a different relationship with land that, for decades, was treated as already lost.

What this means for the rest of us

You don’t have to live anywhere near a desert to feel the ripples of what’s happening in these drylands. Arid and semi‑arid zones now cover over 40% of Earth’s land surface and support more than two billion people. When those areas degrade, they don’t just turn beige on a map. Crops fail, dust storms intensify, and whole families are pushed to migrate towards already stressed cities.

Slowing that degradation with native plants is quietly changing the storyline. In parts of the Sahel where farmer‑managed natural regeneration has taken off, crop yields have risen without chemical fertiliser simply because tree shade and leaf litter have made soils less harsh. In Jordan and Israel, restored shrublands are cutting down dust levels that once choked highways several times each year. A patchwork of small, tougher ecosystems acts like shock absorbers for a warming climate.

There’s also a mental shift hidden in all this. For years, deserts have been framed as either tragic victims of climate change or empty playgrounds for extreme tourism and mega‑projects. Native plant restoration pushes against both images. These landscapes are neither worthless nor fragile ornaments. *They’re working systems that can recover, if we stop asking them to be something they’re not.*

On a personal level, projects like these also scratch at something familiar. We’ve all had that moment where a place we loved looked so damaged it felt pointless to care. Then someone planted something tiny. A street tree in a harsh city. A wildflower patch on a vacant lot. Most of us walked past thinking, “Nice idea, but come on.” The deserts quietly pushing up shrubs and grasses right now are an extended version of that stubborn hope.

We must completely change the way we build homes to stay below 2°C

.

By Michael Le Page in New Scientist

14 January 2026

.

Construction generates between 10 and 20 per cent of the world’s greenhouse gas emissions, but cities can slash their climate impact by designing buildings in a more efficient way

.

 

Cities must reduce greenhouse gas emissions from the construction of buildings and infrastructure by more than 90 per cent in the next two to four decades if the world is to avoid warming of more than 2°C. That means radical changes are needed in the design of buildings, or what they are built from, or both.

“Canada wants to triple its rate of housing construction. The US has a housing deficit, Australia has a housing deficit, [and so does] basically every country you go to right now,” says Shoshanna Saxe at the University of Toronto, Canada. “How do we build so much more while also demanding that we pollute so much less?”

Yet this is achievable, Saxe thinks. “We’re already building buildings that meet these targets; we just have to build more of the good and less of the bad,” she says. “We’ve had these skills and this knowledge for decades; we just have to use it.”

Globally, construction generates between 10 and 20 per cent of all greenhouse gas emissions, with much of that due to the production of cement. To get these emissions down, countries and cities need to know their current construction emissions and then plan how to reduce them in line with global targets.

But when Saxe’s team was asked to do this for the city of Toronto, the researchers were surprised to find that very few studies have attempted to estimate construction emissions on a city level.

“So we decided to come up with a way of getting a rough estimate of how much cities are emitting when they build buildings and infrastructure, and then also how much they could emit in the future to stay within climate limits,” says team member Keagan Rankin, also at the University of Toronto.

Rankin did this for 1033 cities by combining an existing model used to estimate the environmental impact of products over their lifetime – known as EXIOBASE – with data on the population and growth of cities, construction investment and employment, and so on. “This is all available datasets, but he put them together in new ways that we haven’t seen anybody do,” says Saxe.

Finally, the team estimated how fast each city would need to cut construction emissions to stay in line with the remaining global carbon budget for 2°C. These numbers are crucial for planning, Saxe says, “You need to know what the budget per sector is.”

Cities will bust these budgets if they meet housing demand by building single-family homes, the analysis suggests. They need to focus on more efficient multi-unit housing.

Using different materials such as wood or recycled concrete can also help reduce emissions, but better design is even more important, says Saxe.

“It’s very popular to say we’ll just build wood buildings and that solves it,” she says. “But wood also has greenhouse gas emissions. It is only zero emissions if you make all kinds of really optimistic assumptions, including the rate of forestry growth.”

“It’s actually much more effective to design your buildings well so there’s not a lot of wasted space, and wasted structure,” says Saxe.

Rankin says that cities are well positioned to take action. “Cities are very willing to implement climate action, and when it comes to construction, they have a lot of control,” he says. “It’s just, like we found with Toronto, a lot of cities don’t have the resources to go and determine a budget.”

“Without reducing emissions from the construction sector, we cannot meet the Paris Agreement, even if we reduce other emissions to zero,” says Prajal Pradhan at the University of Groningen in the Netherlands. “In my view, it is helpful to view emissions from a city budget perspective.”

It is also important to design buildings to be low-emission over their entire lifetime, not just during construction, says Susan Roaf at Heriot Watt University in the UK, such as by allowing natural ventilation. “We cannot go on developing cities as they have been growing, riddled with super-polluting ‘zombie buildings’,” she says.

Cutting construction emissions also involves prioritising what is built, Saxe says. For instance, Canada is still constructing a huge amount of oil and gas infrastructure. “We could build new housing for 10 million people [without increasing emissions] if we dialled back how much construction we were putting into oil and gas,” she says.

Architecture is an inherently optimistic profession – a quality instilled in me through training and flagged to me in many an interview over the years. Architects set out to change the world, often consciously and purposefully, quite literally shaping the environment around us. It helps to remember this essential positivity at a time when it is easy to get caught up in global events that weigh heavily on our minds.

We celebrate hope and optimism in architecture

At Wallpaper*, we are always keen to champion innovations, ideas and designs that bring hope and optimism, including architectural wonders that put a smile on our faces. There have been quite a few of those over the past year. The 2025 Venice Architecture Biennale had its critics, but it also showcased the architecture world’s hunger for change. Meanwhile, Sarah Housley’s new book Designing Hope discussed specific scenarios that nod to a better outlook for us all.

Also in 2025, Finland was named the world’s happiest country for the eighth year in a row; its ambitious sustainability strategies surely play a role here (policy makers, take note). Elsewhere, ingenious initiatives, such as Retrofit House – a live showcase of sustainable homebuilding techniques, by Civic Square, Dark Matter Labs and Material Cultures – landed to give power to ordinary people.

Above all, it’s the plurality of architectural voices and radical solutions by the world’s creative minds that brings the most hopeful message for a sunnier future. And what better way mark what we look forward to seeing more of than our annual Wallpaper* Design Awards?

In that spirit, a series of our 2026 awards – newly announced in the February issue of Wallpaper* and featured over the coming weeks on Wallpaper.com – celebrates one of the many ways in which we can sustainably diversify building design and construction: working with earth. Once dismissed as ‘backwards’ and unfashionable, building with earth is making a strong comeback. Readily accessible, endlessly adaptable, and honed through generational wisdom, this construction method has many iterations across the world. Polished or textured, geometric or organic, today’s earth buildings look as aspirational as the finest, conventionally built 21st-century villas.

Also for the Wallpaper* Design Awards 2026, we named three Architects of the Year, chosen for having commanded significant attention in 2025. Our winners are Je Ahn, who last year completed a modest yet infinitely glorious home on a British island; Lina Ghotmeh, whose studio is booming with new projects; and Marina Tabassum, who wowed us with her 2025 Serpentine Pavilion.

 

When we interviewed each of them, continuing in our pursuit of optimism, we asked them to name a building that made them smile. We were looking for spatial expressions of serenity – architecture that brings hope and a visceral twinkle. We also ended up talking about everything from height-specific kitchen counters and spilling wine on light-coloured floors to the revelation that architecture need not take centre stage, and we left feeling inspired. Here’s to a great year in architecture – join us as we raise our always-half-full glass.

The past 11 years have been the warmest in the modern era, while oceans continue to heat up, too, says the UN weather agency.

The World Meteorological Organization (WMOconfirmed on Wednesday that 2025 was one of the three warmest years on record, continuing the streak of extraordinary global temperatures.

After analysing eight international datasets, the organization said that global average surface temperatures last year were 1.44°C above the 1850 to 1900 average.

Two of these datasets ranked 2025 as the second warmest year in the 176-year record, and the other six ranked it as the third warmest year.

Warm despite La Niña

The fact that 2025 was very slightly cooler than the three-year average from 2023 is partly explained by the La Niña phenomenon, which is associated with colder weather.

But WMO insisted that any temporary cooling from La Niña is not reversing the long-term trend of warmer temperatures.

“The year 2025 started and ended with a cooling La Niña and yet it was still one of the warmest years on record globally because of the accumulation of heat-trapping greenhouse gases in our atmosphere,” said WMO Secretary-General Celeste Saulo.

The organization added that the high temperatures on land and sea last year helped to fuel extreme weather, including heatwaves, heavy rainfall and deadly tropical cyclones, underlining the need for early warning systems.

Ocean heat

Citing a separate study, WMO highlighted that ocean temperatures were also among the highest on record last year, reflecting the long-term accumulation of heat within the climate system.

Regionally, about 33 per cent of the global ocean area ranked among its historical (1958–2025) top three warmest conditions, while about 57 per cent fell within the top five, including the tropical and South Atlantic Ocean, Mediterranean Sea, North Indian Ocean and Southern Oceans, underscoring the broad ocean warming across basins.

WMO will provide full details of key climate change indicators, including greenhouse gases, surface temperatures, ocean heat and other trends, in its State of the Global Climate 2025 report to be issued in March.

Here’s how to avoid another mountain of waste

The solar boom has a dirty secret. Here’s how to avoid another mountain of waste that can’t be recycled

Solar power has a dark side: panels are still built to be thrown away, and we risk creating a mountain of waste that locks away valuable minerals.

The world already faces up to 250 million tonnes of solar waste by 2050, as panels installed during the solar boom of the 2000s and 2010s reach the end of their service life.

These panels were not designed to be repaired, refurbished, or disassembled. Indeed, current recycling processes mainly extract glass and aluminium, while the materials that carry the highest economic and strategic value such as silver, copper and high-grade silicon are generally lost in the process.

The industry now faces a narrow window to rethink. Without a shift in design, the energy transition could end up shifting environmental pressures rather than reducing them. Building low-carbon technology is essential, but low-carbon does not inherently mean sustainable.

A booming industry designed for the dump

The average lifespan of solar modules is about 25 to 30 years. This means a massive wave of installations from the early 2000s is now reaching the end of its life cycle. Countries with mature solar markets like Germany, Australia, Japan and the US are already seeing a sharp increase in the number of panels being taken out of service.

The challenge lies not only in the scale of the waste but also in the very design of the panels. To survive decades of weather, solar panels are built by stacking layers of glass, cells and plastic, then bonding them together so tightly with strong adhesives that they become a single, inseparable unit.

But this durability has a downside. Because the layers are so tightly bonded, they are exceptionally difficult to peel apart, effectively preventing us from fixing the panels when they break or recovering materials when they are thrown away (those materials could generate US$15 billion (£11 billion) in economic value by 2050).

The limits of recycling

In any case, recycling should be a last resort because it destroys much of the embedded value. That’s because current processes are crude, mostly shredding panels to recover cheap aluminium and glass while losing high value metals.

For instance, while silver represents only 0.14% of a solar panel’s mass, it accounts for over 40% of its material value and about 10% of its total cost. Yet it is rarely recovered when recycling. During standard recycling, solar panels are crushed. The silver is pulverised into microscopic particles that become mixed with glass, silicon and plastic residues, making it too difficult and expensive to separate.

That’s why strategies that aim to extend the life of solar panels – such as repair and reuse – are vastly superior to recycling. They preserve the value of these products, and avoid the massive energy cost of industrial shredding. They keep valuable materials in circulation and reduce the need to extract new raw materials. They can even generate new revenue for owners. But this circular vision is only viable if solar panels are designed to be taken apart and repaired.

Designing panels for a circular future

Moving towards such an approach means redesigning panels so they can be repaired, upgraded and ultimately disassembled without damaging or destroying the components inside. The idea of designing for disassembly, common in other sectors, is increasingly essential for solar too.

Instead of permanent adhesives and fully laminated layers, panels can be built using modular designs and reversible connections. Components such as frames, junction boxes and connectors should be removable, while mechanical fixings or smart adhesives that release only at high temperatures can allow glass and cells to be separated more easily.

Standardising components and improving documentation would further support repairers, refurbishers and recyclers throughout a panel’s life cycle. In short, the next generation of solar panels must be designed to last longer, be repairable, and use fewer critical materials — not simply to maximise short-term energy output.

Digital tools can help

If you want to repair or recycle a panel years from now, you’ll need to know what materials it contains, what adhesives were used and how it was assembled. Digital tools can help here by storing information, essentially acting like a car’s logbook or a patient’s medical record.

One promising example is the EU’s new Digital Product Passport. These passports will include guidance on repair options, disassembly, hazardous substances, lifecycle history and end-of-life handling. They will be introduced progressively for priority product groups from 2027, with further expansion to many other products, expected towards around 2030.

The Digital Product Passport acts as a static “ingredients list” for a solar panel. It shows what a panel is made of and how it should be handled. Digital twins, by contrast, function more like a real-time monitoring system.

Continuously updated with performance data, they can signal when a panel is under-performing, has become too dusty, or needs repairing. Used together, these tools can help technicians identify which parts can be be repaired or reused and ensure solar panels are safely dismantled at the end of their life.

However, even the best digital twin isn’t much use if the panel itself is glued shut and designed for the dump. Without panels that are built to be repaired or taken apart, digitalisation will offer only marginal benefits.

Digital tools also have their own environmental footprint, from sensors to data storage, which makes it even more important that they support genuinely repairable designs rather than compensate for poor ones. We must rethink how we design solar panels right now, before today’s solar boom locks in tomorrow’s waste problem.The Conversation
