Desertification and Regreening

John Harrison

Causes of Desertification

There are two main mechanisms as to why soil is lost to desert and unfortunately civilisation is to blame.

Salinization:

In arid regions, the soil naturally contains salts. When early civilizations (like the Sumerians) built massive irrigation canals to bring river water to the fields, two things happened:

• Waterlogging: Excess water soaked into the ground, raising the water table.
• Capillary Action: As the sun evaporated the surface water, it drew the salty groundwater to the surface.
• The Result: The salt stayed behind while the water evaporated. Over centuries, the soil became so salty that crops (first wheat, then the more salt-tolerant barley) eventually failed entirely.

Destruction of soil structure:

While irrigation poisoned the river valleys, tilling and deforestation destroyed the rest.

• By plowing slopes to grow grain, the Mediterranean and Near East civilizations stripped the "skin" off the earth.
• Without the permanent root structures of perennial grasses and trees (which No-Till mimics), the thin topsoil washed into the rivers during rains.
• This silt then clogged the very irrigation canals the civilizations depended on, requiring massive slave labor to clear until the systems eventually collapsed.

The realisation that farming practices were causing a lot of issues including desertification started long ago and we owe it to the following pioneers who publicised what they thought.

Pioneer ​	Major Work ​	Contribution ​
Eugene W. Hilgard (1870s–1880s)	Proved that irrigation without proper drainage was "poisoning" the soil from below with salt	Adopted as a universal law of arid-land agriculture.
Jacobsen and Adams (1958)	Proved that the Sumerian Empire collapsed because of salt	"Civilization didn't just move; it was pushed out by the salt it created."
Sir William Willcocks (1911)	Noted that the ancients (and moderns) were obsessed with bringing water in but had no plan for getting it out.	First to advocate for a "Main Outfall Drain" which was a second river system designed solely to carry salty wastewater away to the sea before it could sink into the soil
Sir Albert Howard (1940)	An Agricultural Testament	Linked soil organic matter/biology to total ecosystem health.
Edward Faulkner (1943)	Ploughman’s Folly	Proved ploughing was unnecessary and destructive to soil physics.
Masanobu Fukuoka (1975)	The One-Straw Revolution	Applied no-till principles to desertification and "natural" ecosystems.
Ruth Stout (1950s/60s)	The No-Work Garden Book	Popularized "permanent mulch" which prevents the need for tilling in gardens.

David Montgomery and his book Dirt: The Erosion of Civilisations argues that the "life expectancy" of a civilisation is often determined by the rate at which it loses topsoil versus the rate at which it's replaced!

Why Recent Enablement

Thanks to the above pioneers we realised farming practices that had existed for thousands of years were wrong and it is the development of new ways of farming that is l providing the knowledge for the reestablishment of soil.

Before the 1990s, we couldn't measure "Greenness" (NDVI) at scale. Modern projects like China's "Three-North Shelterbelt" and Africa's Great Green Wall now use AI and satellite data to track every hectare in real-time.

The use of cyanobacteria to "seed" the desert is a 21st-century breakthrough that replaces old, expensive mechanical stabilisation.

Drivers for Greening the Deserts

For greening to succeed, it must "pay for itself" through Economic Alignment. Carbon credits often act as a "top-up" or an incentive for long-term maintenance, while other drivers provide the initial momentum:

• State-Led Energy & Engineering (China): In the Kubuqi and Taklamakan deserts, the primary driver is energy production and national security. Massive solar arrays generate electricity for the grid, while the "greening" underneath (licorice and other crops) serves as a secondary benefit that stabilizes the soil around the panels.
• Food Security & Community Resilience (The Sahel): For projects like the Great Green Wall, the primary drivers are ending hunger and creating jobs. While the goal is to sequester 250 million tons of carbon, actual carbon credit markets have historically struggled to drive action on the ground due to low survival rates and verification hurdles.
• High-Tech Efficiency (Middle East): Projects using Liquid Nano Clay (LNC) are driven by the urgent need for water conservation and local food production in water-scarce regions. Reducing water usage by 50% provides immediate cost savings that often outweigh the potential value of carbon credits.
• Interestingly, researchers point to a non-financial driver: atmospheric carbon itself. Rising CO2 levels act as a global fertilizer, helping plants in arid regions use water more efficiently. This effect has caused nearly 70% of the recent "passive" greening observed in world drylands.

Design Principles for Greening Deserts

1. Fit the plant to the water
   Favour native shrubs/grasslands and mixed mosaics; avoid thirsty monocultures in arid belts. China’s water trade‑off research is a cautionary touchstone. [ps.uci.edu]
2. Stabilise first, then plant
   Use chequerboards or similar sand‑fixing to reduce wind shear, then establish durable vegetation. [China's de...solutions]
3. Make restoration pay for itself
   Couple PV, grazing, resin/gum, medicinal plants, and eco‑tourism so restoration creates jobs and revenue, as seen in Kubuqi and GGW value chains. [english.www.gov.cn], [ndep.org]
4. Start with what’s already there
   Apply ANR/FMNR to leverage rootstock and seedbanks before expensive planting. [ndep.org]
5. Engineer microclimates
   Under‑panel shade (agri‑PV), mulches, windbreaks, and biocrusts create micro‑habitats where seedlings can survive. [english.www.gov.cn], [China's de...solutions]
6. Invest in farmer‑centric R&D
   EU pilots like TERRASAFE show that on‑farm trials and co‑design accelerate adoption—tie research to farmer incentives. [ccri.ac.uk]
7. Embed drought governance in national plans
   Follow UNCCD guidance: integrate drought early‑warning, observatories, and finance into land policies; link to health and dust‑storm mitigation. [news.un.org], [weforum.org]

What Success Should Look Like by 2030

• Energy‑Ecology Complexes across suitable Asian and Middle Eastern deserts generate clean power while stabilizing soils and creating rural jobs. [english.www.gov.cn]
• Sahelian Landscapes with millions of hectares under ANR and water harvesting reduce out‑migration, diversify incomes, and buffer drought. [fao.org], [unep.org]
• Mediterranean Dryland Farms deploy soil cover, terracing, and sensor‑guided irrigation, slowing the march of desertification at Europe’s edge. [ccri.ac.uk]
• National Restoration Strategies pair land and drought policy—moving beyond projects to enduring institutions. [news.un.org]

Practical Next Steps for Practitioners and Policymakers

1. Hydrology‑first planning: Map water budgets and select vegetation types accordingly (shrub/grass mosaics where appropriate). [ps.uci.edu]
2. Pilot agri‑PV with native species: Start with 5–50 MW sites in degraded sandy areas; test under‑panel planting, drip lines, and grazing regimes. [english.www.gov.cn]
3. ANR toolkits and tenure: Establish farmer rights and provide pruning tools/training; measure tree‑crown recovery and grazing controls. [ndep.org]
4. Biocrust seeding in hotspots: Apply cyanobacteria on high‑erosion surfaces and protect from trampling for 12–18 months. [China's de...solutions]
5. Blended finance windows: Align restoration with climate, agriculture, and energy funds; use UNCCD/UNEP frameworks for pipelines and monitoring. [weforum.org], [unep.org]

From Degradation to Fertility

Roughly one quarter to two fifths of the world’s land is affected by land degradation and desertification pressures, degrading livelihoods and increasing exposure to drought and dust storms. Recent UN processes (UNCCD COP16, Riyadh, December 2024) urged countries to prioritize land restoration and drought resilience, with work now moving toward a global drought regime and new observatories to track resilience. The economic rationale is strong: every dollar invested in restoring degraded land can return many times that amount in social and ecological benefits, yet finance remains far short of need. [news.un.org], [weforum.org]

The global map of aridity and projections in the World Atlas of Desertification underscores that human activity and to some extend climate change is expanding drylands, meaning scalable restoration is both mitigation and adaptation. [wad.jrc.ec.europa.eu]

How and where the World is Now Healing Its Soils

For generations, we treated soils as if they were inert. We ploughed, over‑grazed, irrigated with often already salty water in areas with no or poor drainage, and left bare surfaces to wind and sun. The result was predictable: erosion, dust, declining fertility and the slow expansion of drylands. We have now learned about looking after soil and how to and not to irrigate and this new knowledge is now being applied for the reclamation of deserts

We are reclaiming soils that were lost from the Sahel to the Loess Plateau, from Chile’s Atacama to Israel’s Negev. This paper lists the major projects that are greening the deserts and tries to cover what is being done, why it is being done and why it works.

Across the planet’s drylands, governments, communities, scientists and entrepreneurs are demonstrating that desertified landscapes can be stabilized, made productive, and ecologically rehabilitated.

China’s megaprojects in the Kubuqi, Tengger and Mu Us sandy lands are among the most visible efforts, combining straw “checkerboards,” biocrust biotechnology, and agri‑photovoltaics at scale.

Africa’s Great Green Wall is restoring a transcontinental belt of the Sahel, supported by UN agencies and new finance commitments; Israel’s Negev shows how precision irrigation and desert agriculture create value in arid zones; and the EU and Middle East are advancing dryland pilots and policies from Cyprus to Saudi Arabia and Iraq.

"Hope for the Future" is found in the educational and moral shift toward three shared principles:

• Community First: Projects succeed when local people own the land. In Senegal, local nurseries are run by the very people who will benefit from the fodder and gum arabic harvested from the "Wall".
• Economic Alignment: Greening must support the local economy through carbon credits, solar energy, or desert-grown crops.
• Ecological Humility & Education: Education initiatives like the 13th World Environmental Education Congress (WEEC) 2026 in Australia highlight the need for cultural regeneration alongside ecological efforts. Similarly, the Faith for Earth Coalition (UNEP) leverages the moral authority of religions to green investments and assets using faith scripts combined with scientific evidence.

Projects

Terrasafe (2024–2029

Runs five rural pilot areas co‑designing innovations to counter specific threats (e.g., soil organic carbon decline in Cyprus, salinisation in Tunisia, water scarcity in Spain). It blends nature‑based solutions with social and technical tools and builds a Desertification Learning Hub for communities (CCRI; Mission Soil platform; TERRASAFE project pages). (CCRI; EU Mission Soil; TERRASAFE) (CCRI, 2024; Mission Soil, 6 Mediterranean Europe & North Africa — TERRASAFE pilots (Horizon Europe)

Terrasafe Pilots are in:

High-Impact Techniques

1. The "Kubuqi Model": Solar-Agri Integration

China’s success in the Kubuqi Desert is perhaps the most visually stunning. They use a "Checkerboard" method—placing straw in a grid pattern to stabilize shifting dunes.

• The "Good Idea": Placing massive solar arrays over these grids. The panels reduce wind speed and provide shade, which drops the soil temperature and cuts evaporation by up to 30%. This creates a microclimate where medicinal plants (like licorice) can grow under the panels, providing an income for local communities while the roots further bind the soil.

2. Africa’s "Invisible Forest": FMNR

In Niger and Ethiopia, the most effective technique isn't planting new trees (which often die without constant water). Instead, they use Farmer-Managed Natural Regeneration (FMNR).

• The "Good Idea": Farmers identify and protect "living stumps"—root systems of trees that are still alive underground but suppressed by grazing or clearing. By pruning and guarding these existing stems, a forest can "re-emerge" naturally. It is 10 times cheaper than planting and has a much higher survival rate because the root systems are already established.

3. Liquid Nano Clay (LNC)

In the UAE, a Norwegian innovation called Liquid Nano Clay is turning sand into soil in just seven hours.

By mixing common clay with water and a "secret sauce" of nutrients, then spraying it onto sand, the particles wrap around sand grains. This allows the sand to hold water and nutrients like high-quality loam. It reduces water usage by 50% and allows traditional crops to grow in the middle of the desert.

The Tactical Landscape: Regional Approaches

While the goal of "reverdure" is universal, the methods vary wildly based on climate, economy, and culture.

De-desertification Projects around the World

1. Kubuqi & Hobq (Inner Mongolia), China & Three Gorges Solar PV Park

China’s “Three‑North Shelterbelt” or Green Great Wall initiated in 1978 has mobilized decades of afforestation and sand control across 13 provinces, lifting overall forest cover and piloting species and methods matched to local conditions.

The Kubuqi Desert in Inner Mongolia has become a flagship for pioneering integrated approaches, with straw checkerboards to stabilize dunes, drought‑tolerant plantings, employment of local communities, and, most recently, agri‑photovoltaic systems that combine PV generation of over 10GW with under‑panel shrubs and irrigation. [thebrighterside.news], [rksi.adb.org], [english.www.gov.cn]

Solar panels not only generate electricity, they cast partial shade and disrupt near‑surface wind, creating cooler, calmer microsites where native shrubs thrive whilst generating much needed electricity. New field data from desert PV stations show improved soil structure and nutrients with suitable vegetation choices (Meng et al., 2025). (Frontiers Plant Science) (Meng et al., 2025). [fao.org]

The Kubuqi Ordos Central‑Northern New Energy Base targets >10 GW of capacity with 8 GW solar + 4 GW wind + 4 GW supporting coal and ~230,000 mu (≈15,000 ha) of PV‑linked sand control, delivering ~40 TWh/yr, cutting CO₂ by ~16 Mt/yr, and creating jobs on site for irrigation and vegetation management under arrays. This “PV + ecology” model is now a core Chinese template for desert restoration with revenue. [english.www.gov.cn]

The shade and reduced wind reduced shear from the solar panels results in lower evaporation, less sandblasting, better seedling survival; revenues from power fund results in long‑term stewardship (Meng et al., 2025; Zhao et al., 2025). [fao.org], [wisdomlib.org]

Peer‑reviewed analyses warned that large‑scale afforestation in arid regions can deplete terrestrial water stores if species or densities are mismatched to hydrology so more recently China’s program has been shifting toward native, drought‑tolerant shrubs/grasslands and mixed mosaics rather than water‑hungry, uniform plantations.

Vegetation, whether for food or cover is now matched to water sustainably available and long‑term hydrologic outcomes are monitored. [ps.uci.edu], [thebrighterside.news]

The result is a gigantic arc of forest and shrub belts now stretches across 13 provinces and is one of humanity’s largest ecological engineering efforts. Visitors can see where sand once moved freely and now holds vegetation and wildlife.

1. Sahel, Africa — The Great Green Wall (GGW)

A 7,000‑km band of restoration stretching from Senegal, Mauritania, Mali, Burkina Faso, Niger, Nigeria, Chad, Sudan, Ethiopia and Eritrea. Communities restore soils using assisted natural regeneration, water harvesting, and agroforestry. Progress is being coordinated and improved through the GGW Accelerator and monitoring systems. [harvardcgbc.org], [standrewse...nomist.com]

Senegal (Louga), Mauritania, Mali, Burkina Faso (Yatenga), Niger (Maradi/Zinder), Nigeria, Chad, Sudan, Ethiopia and Eritrea across the Sahel belt from the Atlantic to the Red Sea.

The initiative integrates forests, grasslands, farms, and community gardens across 11 to 20 countries.

1. Liquid Nano Clay (LNC) Initiatives (UAE, Kuwait & Iraq)

This Norwegian innovation turns sand into soil-like substrate in seven hours.

Once drifting sand, now a living laboratory for restoration. Visitors can see:

• Straw checkerboards stabilising dunes
• Biological soil crust (biocrust) plantations accelerating soil formation
• Massive solar farms creating shade & reducing near‑surface wind so shrubs can grow [fao.org]
• Mechanism: A liquid-based formula of common clay and nutrients is sprayed onto sand, wrapping around grains to hold water and nutrients like high-quality loam.
• Scaling in 2026: Desert Control is applying LNC to 20,000 newly planted trees in Iraq to cut irrigation needs by 50%.

1. The Aravalli Green Wall Project (India)

Launched to protect the Indo-Gangetic Plains from the Thar Desert, this project creates a 1,400 km long and 5 km wide green buffer.

• Goal: To restore 6.45 million hectares of degraded area through afforestation and water body rejuvenation by 2030.
• Digital Monitoring: Plantings are geolocalized and monitored through the "Meri LiFE" portal to stimulate ecological skills in young people.

1. Alto Hospicio, Atacama Desert, Northern Chile

Fog harvesters capture water from the air — up to 0.2–5 litres per m² per day, peaking near 10 litres in high fog months — enough to irrigate vegetation pockets and urban green zones. [studyfinds.org], [frontiersin.org]

• FogNet sites above Alto Hospicio
• Coastal fog‑belt ridges near Iquique

1. "The Green Deserts" Project (Spain/EU)

This project demonstrated the use of "Waterboxx" technology to restore the sponge function of degraded soils.

• Methodology: The boxes capture rain and condensation to support saplings in rocky or desertified areas, increasing survival rates to above 95%.

Communities are restoring soils with assisted natural regeneration (ANR/FMNR), half‑moons and zai pits, farmer‑managed pruning, and agroforestry. The GGW Accelerator and an emerging observatory are improving coordination, monitoring and finance—critical to reach the 2030 ambition (100 Mha restored) (UNCCD partners; GGW hub). (Mongabay; GGW resources/observatory) (Raman, 2025; GGW, 2025). [standrewse...nomist.com], [harvardcgbc.org]

Why it works: ANR leverages surviving root systems and seed banks, making regeneration cheaper, faster and more drought‑resilient than plantation‑only models.

1. The Negev Desert, Israel

World‑leading saline‑water agriculture, precise drip irrigation, heat‑tolerant crops, and desert horticulture research stations. This is one of the clearest examples of soils being pushed back from the edge into productivity.

11. Halophyte & Saline Agriculture Sites (Worldwide)

Halophyte farming is now flourishing in places where salinity once made soil useless.
Major centres include:

• Pakistan’s Sindh coast
• UAE saline agriculture farms
• India’s Gujarat coast
• China’s Yellow River Delta salt farms
  Emerging research confirms halophytes can restore soil functions in salty, degraded lands. [link.springer.com], [hilarispublisher.com]

11. Loess Plateau, China — Iconic restoration, now fine‑tuning water budgets

In Yan’an (Shaanxi) and Tianshui (Gansu) terracing, revegetation and soil rebuilding is transforming one of Earth’s most eroded landscapes. New hydrology papers add nuance: vegetation greening increases evapotranspiration, while moisture‑recycling gains exist but may not fully offset soil‑water drawdown so species choices and planting densities must match water availability (Zhao et al., 2024; Cao et al., 2024). [peerj.com], [besjournal....wiley.com]

The region shows how biophysical success as a result of hydrology‑first planning and continuous monitoring (Cao et al., 2024). [besjournal....wiley.com]

12. Alto Hospicio, Atacama Desert, Chile — Fog turns to water; water turns to soil life

Fog‑collector sites above Alto Hospicio and along the camanchaca (coastal fog) belt near Iquique are now yielding typically 0.2–5 L m⁻² day⁻¹, peaking near 10 L m⁻² day⁻¹ in high‑fog months sufficient for irrigating public greenspaces and small hydroponics when paired with storage.

13. Negev Desert, Israel — Drip, saline agriculture and desert R&D you can visit

The Ben‑Gurion University’s Jacob Blaustein Institute for Desert Research and the Ramat HaNegev Desert Agro R&D Center along with production farms across the Negev have established a hub for desert agriculture using precision drip irrigation, brackish/saline‑water farming, greenhouse cultivation, and water reuse anchored by open research and training programs at BGU (BIDR overview; BGU Canada; campus pages).

Conclusion: The Future is Designed, Not Inherited

The message from China’s deserts, the Sahel’s villages, the Negev’s farms, and Europe’s Mediterranean pilots is the same: desertification is not destiny. With the right mix of ecology, engineering, and economics, degraded land can be stabilized, repurposed, and renewed. The techniques compared here are not silver bullets, but when combined thoughtfully—stabilize, regenerate, monetize, and govern—they turn sand into systems and risk into resilience. That is real hope for the future. [english.www.gov.cn], [fao.org], [ndep.org], [news.un.org]
