Desertification has actually been defined as “the biggest environmental difficulty of our time” and also climate readjust is making the worse.

While the hatchet may lug to mental the windswept sand dunes of the Sahara or the substantial salt pans the the Kalahari, it’s an concern that reaches far beyond those life in and around the world’s deserts, threatening the food security and livelihoods of more than 2 billion people.

The combined influence of climate change, land mismanagement and also unsustainable freshwater use has actually seen the world’s water-scarce regions progressively degraded. This pipeline their soils much less able to support crops, livestock and also wildlife.

This week, the Intergovernmental dashboard on Climate change (IPCC) will publish its distinct report ~ above climate readjust and land. The report, written by numerous scientists and also researchers from across the world, dedicates among its 7 chapters solely to the worry of desertification.

Ahead of the report, Carbon short looks in ~ what desertification is, the duty that climate change plays and what affect it is having approximately the world.

Defining desertification

In 1994, the UN developed the United nations Convention to Combat Desertification (UNCCD) as the “sole legitimate binding international commitment linking setting and advance to sustainable floor management”. The Convention itself to be a an answer to a contact at the UN earth Summit in Rio de Janeiro in 1992 to organize negotiations for an global legal covenant on desertification.

The UNCCD collection out a definition of desertification in a treaty adopted by next in 1994. It states that desertification way “land degradation in arid, semi-arid and also dry sub-humid areas resulting from assorted factors, consisting of climatic variations and human activities”.


Drylands are particularly susceptible come land degradation due to the fact that of scarce and also variable rainfall and poor soil fertility. But what go this deterioration look like?

There are countless ways in which the land can degrade. Among the key processes is erosion – the progressive breaking down and removal of rock and also soil. This is typically through some pressure of nature – such as wind, rain and/or waves – but can be exacerbated by activities including ploughing, grazing or deforestation.

A ns of soil fertility is another kind of degradation. This deserve to be v a ns of nutrients, such together nitrogen, phosphorus and also potassium, or a decrease in the amount of organic matter in the soil. For example, soil erosion by water causes an international losses that as lot as 42m tonnes that nitrogen and also 26m tonnes that phosphorus every year. On farmed land, this inevitably requirements to be replaced through fertilisers at significant cost. Soils can also suffer from salinisation – an increase in salt content – and also acidification from overuse the fertilisers.

Then there are many other procedures that space classed together degradation, including a ns or transition in vegetation type and cover, the compaction and also hardening the the soil, an increase in wildfires, and a decreasing water table through excessive extraction the groundwater.

Mix the causes

According to a current report native the Intergovernmental Science-Policy communication on Biodiversity and also Ecosystem solutions (IPBES), “land destruction is almost always the result of multiple connecting causes”.

The direct causes of desertification deserve to be broadly divided between those relating to how the floor is – or no – managed and those relating to the climate. The former has factors such as deforestation, overgrazing the livestock, over-cultivation of crops and also inappropriate irrigation; the latter has natural fluctuations in climate and global warming together a an outcome of human-caused greenhouse gas emissions.

Then there space underlying causes as well, the IPBES report notes, including “economic, demographic, technological, institutional and cultural drivers”.

Looking first at the duty of the climate, a significant factor is that the land surface ar is warming much more quickly than the Earth’s surface ar as a whole. (Recent research reflects that this is since the “lapse rate” – the price that air temperature decrease with height through the environment – is experiencing bigger decreases over the ocean than land. This results in smaller increases in surface s temperatures contrasted to the land surface ar as global temperatures rise.) So, while worldwide average temperatures are around 1.1C warmer currently than in pre-industrial times, the soil surface has actually warmed by approximately 1.7C. The chart listed below compares alters in land temperatures in four various records through a global average temperature due to the fact that 1970 (blue line).

While this sustained, human-caused warming deserve to by itself add to warm stress confronted by vegetation, that is likewise linked come worsening extreme weather events, explains Prof Lindsay Stringer, a professor in environment and development at the university of Leeds and also a lead writer on the land deterioration chapter the the forthcoming IPCC floor report. She tells Carbon Brief:

“Climate adjust affects the frequency and magnitude the extreme occasions like droughts and also floods. In areas that are normally dry for example, a drought have the right to have a huge impact on vegetation cover and productivity, particularly if the land is being used by high numbers of livestock. Together plants dice off due to lack of water, the floor becomes bare and is more easily eroded through wind, and by water when the rains do ultimately come.”

(Stringer is commenting right here in her function at her home institution and not in her volume as an IPCC author. This is the situation with all the researchers quoted in this article.)

Both natural variability in climate and worldwide warming can also affect rainfall patterns approximately the world, i m sorry can add to desertification. Rainfall has a cooling result on the land surface, therefore a decrease in rainfall can enable soils come dry out in the heat and become an ext prone come erosion. Top top the various other hand, heavy rainfall can erode soil itself and also cause waterlogging and subsidence.

For example, widespread drought – and also associated desertification – in the Sahel region of Africa in the second half of the 20th century has been connected to herbal fluctuations in the Atlantic, Pacific and Indian Oceans, while research also suggests a partial restore in rain was thrust by warming sea surface ar temperatures in the Mediterranean.

Dr Katerina Michaelides, a senior lecturer in the Drylands Research group at the college of Bristol and also contributing author on the desertification thing of the IPCC floor report, describes a shift to drier problems as the main impact of a warming climate top top desertification. She speak Carbon Brief:

“The main impact of climate adjust is with aridification, a progressive adjust of the climate in the direction of a much more arid state – whereby rainfall reduce in relation to the evaporative need – as this directly affects water it is provided to vegetation and also soils.”

Climate readjust is also a contributing aspect to wildfires, resulting in warmer – and sometimes drier – periods that carry out ideal conditions for fires to take hold. And a warmer climate deserve to speed up the decomposition of organic carbon in soils, leaving them depleted and less able to maintain water and nutrients.

As well as physical results on the landscape, climate change can influence on human beings “because that reduces alternatives for adaptation and livelihoods, and can drive civilization to overexploit the land”, note Stringer.

That overexploitation describes the means that humans have the right to mismanage land and cause it come degrade. Perhaps the most obvious way is with deforestation. Removed trees have the right to upset the balance of nutrient in the soil and takes far the roots the helps bind the floor together, leaving that at hazard of being eroded and washed or puffy away.

Forests likewise play a far-ranging role in the water bicycle – particularly in the tropics. Because that example, research released in the 1970s verified that the Amazon rainforest generates around fifty percent of its very own rainfall. This means that clearing the woodlands runs the hazard of leading to the regional climate come dry, adding to the threat of desertification.

Food manufacturing is likewise a significant driver of desertification. Cultivation demand for food have the right to see cropland expand into forests and also grasslands, and also use of intensive farming techniques to maximise yields. Overgrazing of livestock can strip rangelands the vegetation and also nutrients.

This demand can regularly have broader political and also socioeconomic drivers, notes Stringer:

“For example, demand for meat in Europe deserve to drive the clearance of forest land in southern America. So, if desertification is experienced in details locations, its chauffeurs are global and coming greatly from the prevailing an international political and also economic system.”

Local and worldwide impacts

Of course, no one of these chauffeurs acts in isolation. Climate readjust interacts v the other human motorists of degradation, such as “unsustainable land administration and farming expansion, in leading to or worsening countless of these desertification processes”, claims Dr Alisher Mirzabaev, a an elderly researcher in ~ the college of Bonn and a coordinating lead author on the desertification thing of the IPCC floor report. He speak Carbon Brief:

“The decreases in crop and livestock productivity, lose of biodiversity, enhancing chances the wildfires in certain areas. Naturally, these will certainly have negative impacts on food security and also livelihoods, particularly in occurring countries.”

Stringer claims desertification frequently brings with it “a reduction in vegetation cover, so more bare ground, a lack of water, and also soil salinisation in irrigated areas”. This likewise can median a loss of biodiversity and visible scarring of the landscape v erosion and the development of gullies complying with heavy rainfall.

“Desertification has currently contributed to the an international loss that biodiversity”, adds Joyce Kimutai native the Kenya Meteorological Department. Kimutai, who is likewise a lead author on the desertification chapter of the IPCC floor report, speak Carbon Brief:

“Wildlife, especially large mammals, have restricted capacities for timely adaptation come the coupled results of climate adjust and desertification.”

For example, a examine (pdf) of the Cholistan Desert region of Pakistan discovered that the “flora and also fauna have been thinning out slowly with the increasing severity that desertization”. And a research of Mongolia found that “all types richness and diversity indicators decreased significantly” because of grazing and increasing temperatures end the last two decades.

Degradation can additionally open the land approximately invasive varieties and those less perfect for grazing livestock, says Michaelides:

“In numerous countries, desertification way a decrease in soil fertility, a reduction in vegetation sheathe – particularly grass covering – and more invasive shrub species. Nearly speaking, the results of this room less accessible land because that grazing, and also less abundant soils. Ecosystems begin to look different as much more drought tolerant shrubs attack what used to it is in grasslands and much more bare soil is exposed.”

This has “devastating consequences for food security, livelihoods and biodiversity”, she explains:

“Where food security and also livelihoods space intimately tied to the land, the consequences of desertification are specifically immediate. Examples are countless countries in eastern Africa – especially Somalia, Kenya and Ethiopia – wherein over fifty percent of the population are pastoralists relying on healthy and balanced grazing lands for your livelihoods. In Somalia alone, breed cub contributes about 40% the the GDP .”

The UNCCD approximates that approximately 12m hectares of productive land are shed to desertification and drought each year. This is one area that can produce 20m tonnes of serial annually.

This has actually a significant financial impact. In Niger, because that example, the prices of deterioration caused by floor use change amounts to around 11% the its GDP. An in similar way in Argentina, the “total lose of ecosystem services because of land-use/cover change, wetlands degradation and also use of land degrading monitoring practices ~ above grazing lands and also selected croplands” is identical to around 16% of its GDP.

Loss the livestock, reduced chop yields and declining food protection are an extremely visible human effects of desertification, claims Stringer:

“People cope with these kinds of challenges in various ways – by skipping meals to save food; to buy what they have the right to – i beg your pardon is an overwhelming for those life in poverty with couple of other livelihood choices – collecting wild foods, and in extreme conditions, often linked with various other drivers, world move far from impacted areas, abandoning the land.”

People are an especially vulnerable to the results of desertification whereby they have “insecure residential or commercial property rights, whereby there are couple of economic supports for farmers, wherein there are high level of poverty and also inequality, and also where governance is weak”, Stringer adds.

Another impact of desertification is boost in sand and dust storms. These natural phenomena – recognized variously together “sirocco”, “haboob”, “yellow dust”, “white storms”, and also the “harmattan” – take place when strong winds blow loose sand and dirt indigenous bare, dry soils. Research suggests that worldwide annual dust emissions have actually increased through 25% between the so late nineteenth century and today, v climate adjust and land use readjust the crucial drivers.

Dust storms in the center East, for example, “are becoming more frequent and also intense in recent years”, a current study found. This has actually been moved by “long-term reductions in rainfall promot lower soil moisture and also vegetative cover”. However, Stringer adds the “further research is required to develop the specific links in between climate change, desertification and dust and sandstorms”.

Dust storms have the right to have a substantial impact on human being health, contributing to respiratory obstacle such together asthma and pneumonia, cardiovascular issues and also skin irritations, and polluting open water sources. They can additionally play havoc v infrastructure, reducing the effectiveness of solar panels and wind wind turbines by extending them in dust, and causing disruption to roads, railways and airports.

Climate feedback

Adding dust and also sand right into the environment is additionally one that the methods that desertification itself can affect the climate, states Kimutai. Others include “changes in vegetation cover, surface albedo (reflectivity that the Earth’s surface), and also greenhouse gases fluxes”, she adds.

Dust particles in the setting can scatter incoming radiation native the sun, reducing warming locally at the surface, however increasing that in the waiting above. They have the right to also influence the formation and also lifetimes that clouds, potentially making rainfall much less likely and also thus reducing moisture in an currently dry area.

Soils space a really important store of carbon. The height two metres of soil in worldwide drylands, because that example, save an approximated 646bn tonnes that carbon – around 32% of the carbon organized in every the world’s soils.

Research shows that the moisture content of the floor is the main affect on the capacity for dryland soils come “mineralise” carbon. This is the process, also known as “soil respiration”, whereby microbes break down the essential carbon in the soil and also convert it come CO2. This process also provides nutrients in the soil accessible for tree to usage as lock grow.

Soil respiration suggests the soil’s ability to sustain tree growth. And typically, respiration declines with decreasing floor moisture come a point where microbial task effectively stops. While this to reduce the CO2 the microbes release, it likewise inhibits tree growth, which way the vegetation is taking up much less CO2 from the environment through photosynthesis. Overall, dry soils are an ext likely to be net emitters that CO2.

So as soils become much more arid, lock will have tendency to be much less able to sequester carbon from the atmosphere, and thus will add to climate change. Other develops of degradation additionally generally relax CO2 right into the atmosphere, such together deforestation, overgrazing – by stripping the land of vegetation – and also wildfires.

Mapping troubles

“Most dryland environments approximately the human being are being influenced by desertification to some extent,” states Michaelides.

But coming up through a robust global estimate for desertification is no straightforward, describes Kimutai:

“Current estimates of the extent and severity that desertification vary greatly due to absent and/or unreliable information. The multiplicity and complexity that the processes of desertification make its quantification even more difficult. Studies have actually used different methods based upon different definitions.”

And identify desertification is make harder since it tends to emerge fairly slowly, add to Michaelides:

“At the start of the process, desertification may be hard to detect, and also because it’s slow it might take years to realise that a place is changing. By the time it is detected, it might be tough to halt or reverse.”

Desertification throughout the earth’s land surface was an initial mapped in a study released in the journal economic Geography in 1977. It noted that: “For lot of the world, there is little great information top top the level of desertification in individual countries”. The map – shown below – graded locations of desertification as “slight”, “moderate”, “severe” or “very severe” based on a mix of “published information, an individual experience, and consultation v colleagues”.


In 1992, the joined Nations atmosphere Programme (UNEP) published its an initial “World Atlas of Desertification” (WAD). That mapped worldwide human-caused soil degradation, drawing heavily ~ above the UNEP-funded “Global assessment of Human-induced soil Degradation” (GLASOD). The GLASOD task was itself based on expert judgement, with much more than 250 soil and also environmental scientists contributing to local assessments the fed into its global map, i beg your pardon it released in 1991.

The GLASOD map, presented below, details the extent and also degree of soil degradation throughout the world. It categorised the deterioration into chemistry (red shading), wind (yellow), physical (purple) or water (blue).

Shading indicates form of degradation: chemistry (red), wind (yellow), physical (purple) and water (blue), with darker shading showing greater levels that degradation. Source: Oldeman, L. R., Hakkeling, R. T. A. And also Sombroek, W. G. (1991) civilization Map the the condition of Human-Induced floor Degradation: an explanatory keep in mind (rev. Ed.), UNEP and ISRIC, Wageningen.

While GLASOD was also used because that the 2nd WAD, published in 1997, the map came under criticism for a lack of consistency and reproducibility. Subsequent datasets, such together the “Global assessment of soil Degradation and also Improvement” (GLADA), have benefitted indigenous the addition of satellite data.

Nevertheless, by the time the third WAD – created by the Joint research Centre of the europe Commission – came approximately two decades later, the authors “decided to take it a different path”. Together the report place it:

“Land degradation cannot be around the world mapped by a solitary indicator or through any kind of arithmetic or modelled combination of variables. A single global map of land degradation cannot satisfy all see or needs.”

Instead of a single metric, the atlas considers a set of “14 variables often connected with land degradation”, such as aridity, breed boy density, tree loss and also decreasing soil productivity.

As such, the map below – taken native the Atlas – does not present land destruction itself, but the “convergence the evidence” of whereby these variables coincide. The components of the human being with the many potential problems (shown by orange and red shading) – such as India, Pakistan, Zimbabwe and also Mexico – space thus established as particularly at threat from degradation.

The future

As desertification cannot be qualified by a single metric, the is additionally tricky to do projections for exactly how rates of deterioration could adjust in the future.

In addition, over there are many socio-economic chauffeurs that will contribute. Because that example, the number of people directly influenced by desertification is likely to boost purely due to the fact that of populace growth. The populace living in drylands throughout the people is projected to boost by 43% to 4 billion by 2050.

The affect of climate adjust on aridity is also complicated. A warmer climate is generally more able to evaporate humidity from the land surface – potentially boosting dryness in combination with hot temperatures.

RCP4.5: The RCPs (Representative Concentration Pathways) space scenarios that future concentration of greenhouse gases and other forcings. RCP4.5 is a “stabilisation scenario” where plans are placed in place so atmospheric CO2 concentration level off roughly the middle of the century, despite temperatures do not stabilise before 2100. This policies incorporate a change to low-carbon energy technologies and also the deployment the carbon capture and also storage. In RCP4.5, atmospheric CO2 sits at 540ppm by 2100 – around 140ppm greater than currently – indistinguishable to 630ppm when other forcings are included (in CO2e). By 2100, an international temperatures are most likely to rise by 2-3C over pre-industrial levels.

However, climate adjust will also affect rainfall patterns, and a warmer setting can hold an ext water vapour, potentially raising both average and heavy rainfall in part areas.

There is also a theoretical question of distinguishing long-term transforms in the dryness of one area with the fairly short-term nature that droughts.

In general, the global area the drylands is intended to broaden as the climate warms. Projections under the RCP4.5 and RCP8.5 emissions scenarios imply drylands will rise by 11% and also 23%, respectively, contrasted to 1961-90. This would mean drylands could comprise either 50% or 56%, respectively, the the earth land surface ar by the end of this century, up from roughly 38% today.

This expansion of arid areas will occur principally “over southwest phibìc America, the north fringe the Africa, southern Africa, and Australia”, an additional study says, if “major expansions of semiarid regions will take place over the north next of the Mediterranean, southerly Africa, and also North and South America”.

Research additionally shows the climate change is currently increasing both the likelihood and severity the droughts approximately the world. This tendency is most likely to continue. Because that example, one study, utilizing the intermediary emissions scenario “RCP4.5”, projects “large increases (up to 50%–200% in a loved one sense) in frequency for future moderate and also severe dryness over many of the Americas, Europe, southern Africa, and Australia”.

RCP8.5: The RCPs (Representative Concentration Pathways) space scenarios that future concentration of greenhouse gases and also other forcings. RCP8.5 is a script of “comparatively high greenhouse gas emissions“ brought around by rapid population growth, high energy demand, fossil fuel dominance and also an absence of climate change policies. This “business as usual” scenario is the highest possible of the four RCPs and sees atmospheric CO2 climb to approximately 935ppm by 2100, indistinguishable to 1,370ppm once other forcings are had (in CO2e). The likely selection of global temperatures by 2100 because that RCP8.5 is 4.0-6.1C over pre-industrial levels. The relax of the mutual Socioeconomic Pathways (SSPs) has actually introduced a variety of additional “no-new-policy” scenarios, an interpretation RCP8.5 is no longer the single option obtainable to researchers as a high-end no-mitigation pathway.

Another study notes that climate model simulations “suggest severe and also widespread droughts in the following 30–90 year over plenty of land locations resulting indigenous either diminished precipitation and/or increased evaporation”.

However, it have to be listed that no all drylands room expected come get much more arid through climate change. The map below, for example, mirrors the projected change for a measure of aridity (defined together the ratio of rainfall come potential evapotranspiration, PET) by 2100 under climate version simulations for RCP8.5. The areas shaded red are those expected to become drier – due to the fact that PET will increase an ext than rainfall – when those in eco-friendly are meant to end up being wetter. The latter contains much of the Sahel and also East Africa, and India and parts that northern and also western China.

Climate model simulations likewise suggest that rainfall, once it go occur, will certainly be more intense for virtually the entire world, potentially enhancing the risks of floor erosion. Projections suggest that many of the people will view a 16-24% boost in heavy precipitation soot by 2100.


Limiting global warming is therefore one of the an essential ways to help put a break on desertification in future, but what other solutions exist?

The UN has actually designated the decade from January 2010 come December 2020 as the “United countries decade for deserts and also the fight versus desertification”. The decade was to be an “opportunity to make an important changes come secure the long-term capacity of drylands to provide value because that humanity’s well being”.

What is an extremely clear is that prevention is far better – and much cheaper – than cure. “Once desertification has arisen it is very daunting to reverse”, says Michaelides. This is since once the “cascade of destruction processes start, they’re hard to interrupt or halt”.

Stopping desertification prior to it beginning requires steps to “protect against soil erosion, to stop vegetation loss, to protect against overgrazing or floor mismanagement”, she explains:

“All these things call for concerted efforts and also policies from communities and governments to manage land and water sources at large scales. Even small scale floor mismanagement deserve to lead to degradation at larger scales, for this reason the problem is quite facility and tough to manage.”

At the UN Conference top top Sustainable development in Rio de Janeiro in 2012, parties agreed to “strive to achieve a land-degradation neutral civilization in the context of sustainable development”. This ide of “land degradation neutrality” (LDN) was subsequently taken increase by the UNCCD and additionally formally embraced as Target 15.3 that the Sustainable advance Goals by the UN basic Assembly in 2015.

The idea that LDN, explained in detail in the video below, is a power structure of responses: first to stop land degradation, 2nd to minimise it where it does occur, and also thirdly to counter any new degradation by restoring and rehabilitating soil elsewhere. The outcome gift that all at once degradation comes into balance – wherein any new degradation is compensated through reversal of vault degradation.

“Sustainable land management” (SLM) is an essential to afford the LDN target, states Dr Mariam Akhtar-Schuster, co-chair the the UNCCD science-policy interface and also a review editor because that the desertification thing of the IPCC soil report. She tells Carbon Brief:

“Sustainable land management practices, i m sorry are based upon the neighborhood socio-economic and ecological problem of one area, help to avoid desertification in the very first place but likewise to minimize ongoing destruction processes.”

SLM essentially way maximising the economic and also social services of the land while additionally maintaining and enhancing its productivity and also environmental functions. This can consist of a whole range of techniques, such as rotational grazing that livestock, raising soil nutrients by leaving chop residues on the soil after harvest, trapping sediment and also nutrients that would otherwise be lost through erosion, and also planting fast-growing trees to carry out shelter from the wind.

But these steps can’t simply be applied anywhere, note Akhtar-Schuster:

“Because SLM needs to be adapted to neighborhood circumstances there is no such thing as a one size fits all toolkit to protect against or alleviate desertification. However, every these locally adjusted tools will have the best effects if they are embedded in an incorporated national land use planning system.”

Stringer agrees the there’s “no silver bullet” come preventing and also reversing desertification. And, the not always the same people who invest in SLM who benefit from it, she explains:

“An instance here would certainly be land customers upstream in a catchment reforesting one area and also reducing floor erosion right into water bodies. For those world living downstream this reduce flood risk as over there is less sedimentation and also could additionally deliver boosted water quality.”

However, over there is additionally a fairness problem if the land customers upstream space paying for the brand-new trees and those downstream room receiving the benefits at no cost, Stringer says:

“Solutions as such need to identify who ‘wins’ and also who ‘loses out’ and should incorporate techniques that compensate or minimise inequities.”

“Everyone forgets that last part about equity and also fairness,” she adds. The other facet that has additionally been overlooked in history is getting ar buy-in on propose solutions, states Stringer.

Research shows that using classic knowledge have the right to be particularly beneficial for tackling soil degradation. No least because communities life in drylands have actually done so properly for generations, in spite of the tricky ecological conditions.

This idea is increasingly being tackled board, says Stringer – a an answer to “top-down interventions” that have actually proved “ineffective” since of a absence of neighborhood involvement.
