Top 10 amazing deserts in the world to visit

Ranging from vast, lifeless expanses to great plains, which are home to many people, deserts are so much more than the typical stereotypes award them in our mind’s eye.

Roughly 33% of planet earth is desert. From the icy stretches of the earth to towering sand dunes and salty stretches, these are ten amazing deserts in the world to visit.

For those looking to, quite literally, get off the beaten track, deserts are a great place to discover. Read on to learn about ten amazing deserts in the world to visit.

10. Painted Desert, USA – for colourful landscapes

The Painted Desert is a well named.

As the name implies, this Arizona desert in the United States is almost a painter’s palette. The brilliant landscape is scattered in various colours as far as the eye can see.

With little rainfall each year, the colours are caused by sandstone rock and clay minerals. Neighbour to the Grand Canyon, this is a fabulous stop on a West Coast road trip of America.

9. Thar Desert, India/Pakistan – the desert home to many

Thar Desert is one of the most amazing deserts in the world.

Deserts are often portrayed as deserted landmasses, sterile and empty of life. The Thar Desert, however, challenges this notion.

Many communities and towns thrive in this region and give fantastic local insight into traditional life for travellers seeking an authentic experience.

8. Pinnacles Desert, Australia – the coastal desert

Pinnacles Desert in Australia is a must-visit.

For those craving a little bit of beach life while they enjoy a desert adventure, we suggest you look to the Pinnacles Desert in Australia.

This desert is denoted for its natural rock masses, which point up to the sky like fingers from the earth, surrounded by sand dunes.

7. Salar de Uyuni, Bolivia – for salty stretches

Salar de Uyuni is one of the most amazing deserts in the world.

Salar de Uyuni in Bolivia is another one of the amazing deserts in the world to visit. It is the world’s largest salt desert, and many recognise this unique landscape for its vast expanses of parched salty terrain.

In fact, an estimated 10 billion tonnes of salt lies in this Bolivian desert.

6. Gobi Desert, China/Mongolia – for ice-capped sand dunes

The Gobi Desert is truly incredible.

When we think of a sandy desert, we expect immense heat and relentless sun. What may not come to mind is ice-capped dunes. However, this is quite the case with the Gobi Desert that stretches between China and Mongolia.

It is one of the largest deserts in Asia, and one of the amazing deserts in the world to visit, no doubt.

5. Rub’ al Khali, Saudi Arabia – the desert of dunes


If sandy settings sound to your liking, there’s no better place to explore than the Rub’ al Khali in Saudi Arabia.

This is the world’s largest sand desert. It is bound to impress with over 583,000 square kilometres (225,000 square miles) of dunes.

4. Antarctica – the ice world

Antarctica is an ice world.

For true explorers, the ice world of Antarctica awaits. This is one of the most intriguing destinations on the planet and has been attracting adventurers for centuries.

Today, for a pretty penny, you can enjoy tours of this epic region of the earth. Here, you will get to enjoy some of the world’s most majestic creatures.

3. Namib Desert, Africa – the world’s oldest desert


The Namib Desert, which lies along the coast of South Africa, is the oldest desert in the world.

With brilliant red earth that hugs the South Atlantic Ocean, this spectacular sight is one that won’t be soon forgotten.

2. Sahara Desert, Africa – the most-famed desert

The Sahara Desert is perhaps the most famous desert in the world.

The Sahara Desert is perhaps the world’s most famous desert. It is the largest hot desert in the world and only smaller than those in the icy tip and tail of the planet (Antarctica and northern Arctic desert).

Dominating North Africa, this desert spans 9.4 million square kilometres (3.6 million square miles). Plus, it is coined as being one of the harshest environments for survival on the earth.

1. Mojave Desert, USA – for cultural and natural attractions

The Mojave Desert is up there with the best deserts in the world to visit.

The Mojave Desert in the United States touches on the states California, Arizona, and Nevada. It is home to various towns and communities, as well as Death Valley – one of the lowest and hottest places on earth.

Given its proximity to Las Vegas, the Grand Canyon, and the Californian coastline, this is one of the most amazing deserts in the world to visit. It is particularly popular with road trippers.

7 fun things to do in the desert

It’s no surprise that deserts are among the most daunting places on Earth. Some may think they’re best avoided.

But for the rest of us, these arid wildernesses can make for the ultimate travel playground. Read on for seven desert destinations around the world and a fun thing to do in each:

Namib Desert, Namibia: Horseback riding

Get in the saddle and really get to know Namibia.

Galloping through the world’s oldest desert region is certainly not for travelers with weak hearts or thighs.

If remote landscapes are your thing, however, a bit of man-beast bonding in the Namib Desert should fill your Instagram feed for a month.

Rides can take you through the bush savannah and the Hakos Mountains, passing canyons, coastlines and oases and ending up at the shores of the Atlantic Ocean at Swakopmund.

Along the way you’ll see wildlife in its natural environment: mountain zebra, oryx, ostrich, springbok and maybe even desert warthogs.

Lahbab Desert, United Arab Emirates: Dune bashing

One place where driving in a straight line will get you in trouble.

Less than an hour’s drive from the bright lights of urban Dubai, this is a desert-lite experience for visitors who want the adrenaline rush of being out in the sands without too much effort.

You and your buddies can climb into a sturdy four-wheel drive and let your driver take on the might of Lahbab Desert sand dunes for you.

All you’ve got to do is sit tight and keep your eyes open — not easy when your stomach is rolling, sheets of sand are spraying against the windows and your driver is pumping nauseatingly upbeat chart hits from tinny speakers.

Sonoran Desert, Arizona: Hiking

Hiking through an

If you want a less intense desert experience and the chance to take in as much nature as possible, you need to get to Arizona.

One of the world’s most “alive” deserts, a slow-paced trek through Sonoran Desert allows you to see coyotes, roadrunners, mountain lions, zebra-striped lizards and more amazing desert-dwelling critters, as well as what hike organizers describe as a “botanical garden of desert plants.”

Some of the hikes across this region are more grueling than others — you can choose a level that suits your stamina.

Usaka Desert, Peru: Sandboarding

Sandboarding is similar to snowboarding but takes place on sand dunes.

Well then, the last terrain you need to conquer by board is the desert. You can do sand surf anywhere there are sandy slopes.

All you need is a sandboard and a lot of determination — hauling yourself back up the sand dunes after each run can be agonizing.

Many adventure companies rent out boards and teach the basics as part of desert safaris so you can get a feel for the sport.

Nevada’s deserts, United States: Hang gliding

What better place to gaze at the endless rolling landscapes of a Nevada desert than from high above it?

You won’t have to put up with intense heat, sandy winds or back-breaking dune climbing to get a decent view — it’ll all be laid out beneath you.

There’s an active hang-gliding scene in Nevada, and plenty of centers that can get you airborne. Don’t worry — you won’t just be strapped into a harness and launched off a hillside. Or you can fly tandem with an experienced hang glider pilot.

Thar Desert, India: Camel racing

Camel race during the Desert Festival in Jaisalmer, India.

Running camels look, in a word, demented. They have none of the elegant power of horses or the raw grace of big cats. Their legs splay crazily out to the sides, Bambi-style. And they seem permanently off-kilter.

But don’t be fooled by their awkward appearance. Camels can gallop at up to 64 kph (40 mph) in short bursts. At major racing events, big bucks are often at stake.

Events take place in various deserts, but one of the most riotous events is the Bikaner Camel Festival, held each January in the Thar Desert of northwestern India. Here, you’ll also see camel processions, milking and competitions for the best decorated camel.

Sinai Desert, Egypt: Quad biking

Tourists ride quad-bikes during part of a desert safari trip in Egypt.

Quad biking might look a little on the rough-and-tumble side, but in fact they’re much smoother to drive than they look.

Deserts as Ecosystems and Why They Need Protecting

Deserts as Ecosystems and Why They Need Protecting

Deserts conjure up specific ideas about topography: typically, that they are dry and sandy dunes or rock, or a mixture of both. But deserts are far more than this and there are multiple types. How we define the desert biome are not about the types of rock, or the amount of sand, or even the temperature because there are both cold and hot deserts. The simple explanation is that deserts are topographic landscapes that receive little precipitation in a typical year. The threshold is 10 inches, or 25cm. But more than simply having low rainfall, a desert is “arid”. This means a high rate of water loss through plant reclamation (called transpiration) and through evaporation. These two aspects are combined into something called evapotranspiration. This is the amount of water that the landscape would lose when available (1). For deserts, evapotranspiration ratio exceeds average annual rainfall by anything from 2:1 to 33:1. The higher the ratio, the less available moisture there is. The coarse nature of the soil means most moisture seeps through the top soil rapidly.

Furthermore, what precipitation a desert does experience is erratic. The average rainfall is just that. A desert may receive far more than the “average” in one year and not experience any rainfall the year before and the year after. Deserts will differ depending on their climate and location and their overall aridity can influence many things, not least of all the ecology, food chain, plant and animal types. High evaporation leaves behind higher salt levels, affecting further which plants can grow and the individual size and the numbers of herbivores that may feed on them and, in turn, carnivores. Some experience vast temperature fluctuations, especially hot deserts which may reach unbearable heat during the day and extreme cold at night (2). This is because the rock and sand absorb heat during the day and releases it at night. There may also be an extreme variation between warm and cool seasons, including extreme winds and storms due to the mixing of cold and warm air.

Deserts are vitally important to the planetary ecosystem. They cover approximately 1/3 of the dry land of our planet (3, p1). They are also amongst the most fragile and endangered biomes.

Types of Desert

There are four broad types of desert: coastal, cold, hot & dry, and semi-arid.

Coastal Deserts

These are generally hospitable and don’t have the extreme temperature fluctuation that other types experience. Life is more abundant here, the soil less acidic, and tend to be arid due to adjacent topography such as mountain ranges or lakes and waterway networks that draw off most of the precipitation that they would otherwise experience (4). Coastal deserts experience a brief winter of moderate average temperatures of 5�C/41�F for winter while summer typical reaches an average of between a mild 13�C/55�F to warmer 24�C/75�F. The precipitation is lower, and this type of desert is better at retaining what little moisture it harnesses – on average around 5 inches or 13cm annually.

What isn’t drawn off by mountains drains away from the porous soil to find its way into waterways a little farther away. An example of the coastal desert is the Namib.

Cold Deserts

Not the first thing that comes to mind when we think about deserts but located in the most extreme latitudes, they fall into two broad types:

  • A long way from coastal areas and in a cold zone, receiving low precipitation
  • In proximity to mountain ranges which draw away precipitation that might otherwise have created tundra or plains

Its annual precipitation falls as snow which may sometimes remain on the ground until the summer before it melts. If the temperatures don’t rise sufficiently, it may remain for over a year. Their winters are extremely cold, typically between -2 and 4C (28.4F to 39.2F). Summer temperatures are pleasant and surprisingly warm, typically on average between 21 and 26C which is between 69 and 79F. Precipitation is relative and although fall and winter receives most of it, it is generally lower than other landscape types and it is insufficient to support too much life – hence why they are considered deserts.

An example of a cold desert is the Gobi (5). Some feel that Antarctica’s interior is a desert due to low precipitation.

Hot & Dry Deserts

What we think of as the “typical” desert, usually indicated with the sand dunes of North Africa and the Middle East, isn’t quite as empty, hot or bleak as we might think. While they do have hot summers (43-48C or 110-120F), the annual average is a much cooler 20-25C or 68-77F. Night temperatures are an average 10C or 50F. They also experience cold winters, a season in which the low levels of precipitation usually fall to -18C. Summer night-time temperatures drop considerably which is why the annual averages are so extreme. Surface albedo is high – heat acquired during the day is radiated at night. This type experiences no more than 11” (28cm) of rainfall annually while many experience even less than that. Evidence from The Atacama Desert, for example, suggests that some areas have never experienced precipitation. Their barren appearance is broken by the occasional tree; shade and coverage is rare, and this is where you are most likely to see sand dunes.

The Sahara is a hot and dry desert (6).

Semi-Arid Deserts

Semi-arid deserts have, by definition, higher levels of precipitation compared to the other three types featured here, although not a great deal more. They are also not limited by temperature. They are milder generally, but they can exist farther to the north, meaning there are colder and warmer types. Daytime and nighttime temperatures are not as extreme, and neither are the divisions between summer and winter. There is some debate over whether they should be considered deserts at all but a type of plain or “steppe”. However, others argue that the other topographical features – of low precipitation (1-2” or 2-4cm annually) and high evapotranspiration leave them firmly in the desert category. Examples of colder semi-arid deserts include the Nearctic zones which incorporate Newfoundland and Greenland. Warmer examples are the Sagebrush of Montana and the Great Basin, and much of Australia’s Outback (7). Summer average temperatures are between 21 and 27C while rarely going above 38C as the hot & dry types of desert often do.

A Brief History of the Use, Study, and Conservation, of Deserts

In Antiquity

Deserts, despite a reputation in some quarters as a barren and useless wasteland or as problems to be solved, have been a way of life for many different peoples. Ancient Egyptian society began along the fertile banks of the River Nile which is buffered on both sides by hot & dry desert (8) which they saw as vital to their culture. Some attribute the arid environment of the Egyptian interior to the development of their complex culture and especially their rituals and cults surrounding death. It is particularly believed that the desiccated nature of bodies as found in the desert dying of exposure or from natural causes provided inspiration for their experiments and developments leading to the mummification process. Certainly, the dry environment of western Egypt where the pyramids are located would have been the perfect environment to prevent the sort of cadaver degradation seen in biomes with higher precipitation and humidity. Similar theories have been expressed about the development of mummification in the South American culture of the Chinchorro who lived in the Atacama Desert, quite possibly the driest desert on the planet (9).

Even before this, the deserts have provided useful environments for resources and hunter-gathering. Various tribes of Native Americans made their homes in the deserts of North and Central America, as did the Kalahari Bushmen and Australian aborigines. Deserts are ideal for tracking animals and provide enough food in the right volumes to support hunter-gathering communities. It’s no wonder we find so much archaeological remains in deserts. Firstly, they were well-used by people of the ancient past and secondly, the lack of humidity increases the chances of survival of organic material. Other cultures quickly adopted semi-nomadic lifestyle and took livestock with them on long journeys across the desert, learning locations of water and living off the animal produce, using animal skins as tents for shelter, and utilizing other parts of the animal such as milk, bones, and meat. Even today, peoples such as the Bedouin still roam the deep deserts of the planet although their lifestyle is more semi-nomadic (10).

The Age of Exploration to the Modern Age

Successive civilizations harnessed the resources available in deserts for millennia, from mining to harnessing water supplies from springs into irrigation to grow crops, and stone, deserts have generally been seen as a resource. It wasn’t until the early Middle Ages and the explorations the likes of Marco Polo that we begin to see wonder and observation in the desert biomes, particularly the Gobi (11). This was part of the Silk Road, the trade route between the Far East and Europe which was vitally important to the Eastern Roman Empire and the Alexander’s Greek Empire before it. By Marco Polo’s time, the journey was well-established, but his writing was the first volume. Polo and his father were the first westerners to visit China’s modern capital. He was famously appointed to the Chinese Royal Court. Today, Marco Polo is one of the world’s most famous early explorers, inspiring the likes of Christoper Columbus and Ferdinand Magellan.

It would take several hundred years and the travels of Charles Montagu Doughty before any more important works were to come; his two-volume book Travels in Arabia’s Deserts was published in 1888. He would later prove to be one of the most inspirational early travel writers to the modern age (12). The work included many observations about deserts and their uses, functions, and the sense of wonder. It is valued as much for its vivid descriptions and beautiful writing as it is for its content. Slightly later Antoine de Saint-Exupéry utilized the new transport of flight to bring a new dynamic to travel over deserts; a plane crash in the Sahara almost killed him but he was found by Bedouins (13). His travels in the Arabian deserts were extensive, as were those of Gertrude Bell – one of history’s most famous female explorers. Yet her work could not hold a candle to the phenomenal work of Freya Stark (14) who published 20 books featuring the deserts of the Middle East. Other important figures in the early 20 th century include naturalist Uwe George who lived in several deserts for part of his life and poet Robert Frost who also explored them.

Eremology: Preservation of Deserts as Ecologies and Cultures

Until the early-mid 20 th century, interests in deserts was one purely of exploration and travel, as highlighted in the previous section. The birth of the science of eremology (the study of the desert biome) began in the mid-20 th century and with the dawning of the understanding of such environmental concepts as human geography, ecology, and, of course, conservation. It had been widely known thanks to various travel volumes that deserts were anything but lifeless wastes. One of the earliest remits of the United Nations was conservation. A growing problem in the 1960s concerning such issues as pollution and public health led to the development of a number of environmental standards and conservation issues for the assembly of world powers. UNESCO now has a chairperson dedicated to Eremology, such is the importance of the preservation of the desert biome for cultural and ecological reasons; as discussed previously, various peoples have lived in deserts for millennia and it remains an important part. This role has been in place since 1994. Today, researchers into the desert biome understand the importance of their conservation for these reasons, but also for biodiversity (15) and the unique biological makeup of such landscapes. Many species that live and thrive in desert environments do not exist in other biomes.

Yet eremology is also the study of how deserts are formed. As well as preserving the deserts that we have, it is also dedicated to ensuring that human activity such as climate change, agricultural practices, intensive resource use and other activity does not create deserts in other landscapes, ecosystems and biomes. The UNCCD (United Nations Convention to Combat Desertification) (16) now has a delicate balancing act between preservation and holding back desertification.

The Academic, Functional, and Ecological Importance of Deserts

Deserts as Rich Archaeological Sources

Some of our greatest archaeological finds have come from desert environments. As with anaerobic conditions of wetlands where organic material is cut off from microbes, such material survives in deserts due to the lack of moisture and bacteria that can eventually break it down. This is the reason for the survival of many pre-dynastic Ancient Egyptian bodies from shallow graves in the desert. Without the low humidity and desiccation, they are unlikely to have survived so well (17, p60). These bodies predate the mummification process and therefore, no embalming fluid or removal of organs that degrade quickly as seen in the later industrial process of the complex society. The same is true with the mummies of the Chinchorro peoples of the Atacama (a cold desert). What is most remarkable about these mummies is that they predate the Egyptian society by some 2,000 years and they used some of the same techniques at times (9).

But the archaeology of deserts is about far more than simply the preservation of artefacts and their improved chances of survival. Various archaeological disciplines examine other areas of the desert.

  • Desert Phenomenology / Experiential Archaeology: This is an archaeological approach that seeks to understand how people live in the deserts, their life experiences, and how they perceive their local environment(s). It includes their sensory experiences of day-to-day living
  • Desert economy: Deserts have always been vital for resources and economy. Sand and stone have been used to build structures where wood is sparse as is the case with Ancient Egypt. But they are also sources of precious metal and gem mining
  • Water: Deserts are areas of low precipitation and low humidity which seems in direct conflict to the requirement of water for all living things. It’s a great source of examining technologies from the simple to the complex, of acquiring, harnessing, storing and preserving water and its supply. But more than that – what importance (practical or spiritual) do those people place on water?
  • Deserts landscape archaeology and human geography: Particularly of the routes crossing deserts and the links between cultures within them, at the borders of deserts, and further afield. The study of routes can include migrations of people, when and how they move, the logistics of movements and regular pathways such as the Silk Road

Water engineering and mechanics are also of interest to archaeologists of desert areas. It’s an interesting area of study that shows both human ingenuity and human potential for self-destruction. The irrigation of Mesopotamia during the first civilizations is one of the most remarkable feats of both. In the first instance, filtering water from the Euphrates and the Tigris rivers to the desert interior allowed for the building of enormous cities. The region, despite having lush valleys around and between the rivers, had much lower precipitation than Egypt which relied on annual Nile flooding (18). Yet the irrigation that allowed for the civilization to develop was also its downfall as over-irrigation led to consistent crop failure as water evaporated, leaving behind salts that would eventually saturate the land (19).

Desert Ecology and Biodiversity

The reputation of deserts as cold and lifeless is unfounded and it has arguably led to desert biomes being ignored in research literature compared to others (20). Many certainly seem bereft of life, certainly during the day in summer in hot deserts when temperatures are potentially scorching, and winter in some cold deserts where subzero temperatures make life difficult. However, they are abundant with both flora and fauna. What is so great about deserts as biomes, is their unique biological profile. Species exist in these environments that simply do not appear elsewhere. The Mojave Desert is a case in point; it’s one of the harshest environments on the planet with a humidity level that rarely goes higher than 40%, yet it maintains abundant biodiversity throughout the seemingly barren topography (21). All species have adapted to live in this harsh environment and many are protected because of their geographical limitations and delicate ecological requirements of coping with the high temperatures and dry environment.

Typical botany include succulents such as cacti which do not have leaves like other species, but spines to protect the fleshy body of chloroplasts adapted to store water, and shallow roots to quickly absorb the little moisture that makes it into the topsoil before evaporating away or soaking through. Similar specialization is also true of fauna which have high water retention, do not have the capability to perspire, and tend to be cold-blooded and small. Larger animals and mammals are rare although this is not always the case.

  • Kangaroos, for example, which live in the hot desert climate of Australia are warm-blooded mammals and must find shelter during the hottest part of the day to avoid overheating. They have, however, developed a great defense mechanism against extreme heat in that they lick their bodies and the saliva cools the blood (22)
  • Camels survive well in deserts because of their high water retention and survive quite happily in temperatures up to 48C / 120F.

These are two rare examples of both warm-blooded and larger animals that live in hot desert environments.

But what about cold deserts? They have received less attention than their hotter or semi-arid counterparts. We do understand that as they are in the extreme latitudes, that means most cold deserts tend to experience periods (months) of continual dark in the winter and periods of continual sunshine in the summer. This too has an impact on local biodiversity. Like their hotter counterparts, plants must be drought resistant. But succulents do not survive in these environments because of the cold. The most common type of plant in cold deserts are grasses and they form in clumps on rocks and in areas where the little moisture is most abundant. Shrubs occur in some places and the types of plant you might see on scrubland, but this is rare. Trees are also rare with only a handful of species such as the camel thorn acacia in the Gobi (23) and the pistachio tree which grows in the cold deserts of Iran.

Animals in cold deserts are warm-blooded and larger than their hot desert counterparts. Typical examples include types of deer and antelope present in most cold deserts, sheep and goats likewise, and in South America llamas and alpacas. As far as carnivores are concerned, this is the realm of the wolf, the snow leopard, and jackals, depending on where in the world the desert is located. Small mammals are much more abundant and cold blooded reptiles are less abundant. In fact, scorpions appear in just one cold desert – the Iranian Desert.

Deserts as Climate Indicators

Desert is one biome type that researchers and conservationists do not want to expand all the while ensuring that the deserts we presently have do not disappear. The major reason for this is that desert is of low agricultural quality, low biodiversity, and an extreme environment. Climate change presents a risk of desertification of present marginal landscapes. We know this occurs from paleoenvironmental data (24). Many of our deserts contain the remnants of ancient lakes, indicated by former water channels and preserved biotic and abiotic materials indicative of previous presence of water. As deserts are the most extreme environments on the planet, they are prone to the most change. Radiation is intense – both in terms of how much deserts receive and how much they reflect back into the environment. The expansion of desert can directly impact global average temperatures further, increasing water evaporation in adjacent areas. Even though the plant and animal species that exist in hot deserts are well-adapted to those environments, we know from studies that such organisms are treading a fine line over environmental tolerance; some are even at their limits, according to the IPCC (25).

Both The Sahara and The Namib are extremely hot deserts and in recent years have experienced some of the hottest temperatures to date. Pakistan and Iran have also experienced record dry spells and high temperatures in the last decade. Even semi-arid desert climates are experiencing an increase in hot and dry spells, becoming more parched and experiencing wildfires in areas where scrub, brush and tree cover is more abundant. California, for example, has always experienced summer wildfires but the season for the fires is getting longer with the increased drought the state is experiencing. Continued drought, lowering precipitation and a dropping of the water table means plants cannot grow as abundantly. This creates a high risk of expanding desertification. The risks are highest in the 50�S-50�N range which is the latitudes within which the hottest and driest desert climates presently are (26). Evidence demonstrates that the deserts of the Arabian Peninsula alone show increased water vapor feedback, much higher sensitivity, and increased sensitivity in deserts to greenhouse gas emissions. Simply, deserts become hotter and drier during a warming climate with wider implications for the warming climate. That makes this type of biome one of the most useful types for understanding and tracking climate change now and for the future.

Desert Resources

As well as biodiversity and their cultural significance, deserts are also useful economically due to their unique geological profiles or their environmental formation processes. The desert biome is one of the most important. There are 15 mineral deposit types on our planet and 13 of them are found in deserts. This makes the desert an important place for mineral resources and for local and global economy. The reason this is the case is how water leaches through the ground or through evaporation so quickly that mineral deposits are left behind. We discussed the problem with irrigation in Mesopotamia in the archaeology section where increased salt deposits made agriculture more difficult. This is a similar but natural process and it leads to the formation of large metal deposits in particular. Typical mineral resources found in desert regions (both hot and cold) include salt and borates, and gypsum. Borates occurred in high density in the Great Basin Desert here in the US. From there, borate was taken to Death Valley to the emerging railroads and all over the country (27). This special kind of salt is used to manufacture glass, enamel and other ceramics, and in the pharmaceutical and agrichemical industries. All of it was mined from the dried beds of paleolakes that once existed in the region. It is estimated that the value to the US economy of borates alone has topped $1 billion. The US deserts are also home to copper.

Salts have also proven a great resource for the Chilean economy although today its lithium resources have also taken prominence on the world stage as battery development increases for better power storage and production in the new generation of electric cars (28). No other desert has as much abundant salt as this desert. It is estimated that during the First World War alone, some 3 million metric tons were mined. Like the US deserts, copper is present in Chile. Australia’s deserts are a source of lead and zinc, uranium, gold and silver. As far as non-metal resources are concerned, deserts are also home to clay, beryllium, pumice (where there was past volcanic activity), nitrates and lithium. It is also no great surprise that some of our most abundant oil deposits are found in desert regions, particularly the Middle East, central and South America, in the driest places on Earth. These were once marine environments, but the lakes and seas dried up, allowing for the chemical processes that turn organic material into crude oil to create enormous deposits. Oil is not unique to dry environments though and the most important process is the presence of organic material and the right chemical conditions.

Deserts as a Way of Life

There is some debate whether the Bedouin tribes of the Middle East are true nomads in the traditional sense. They certainly perceive their lifestyle in this way although technically they live a semi-nomadic life. In summer, they settle on lands bordering deserts where agriculture is possible and food crops for livestock is abundant. They tend to move around a lot more in the fall and winter time during the rainy season (29). There are different groups of Bedouin tribe who name and classify themselves based on the types of livestock and animals that they rear. For example, there are camel Bedouins which comprise the largest tribes and are distributed over the widest areas of the Middle East, incorporating most of the Levant (Jordan, Syria, Iraq) the Arabian Peninsula and North Africa including Egypt, Libya and Sudan.

Much of their lifestyle is unchanged since the Bedouins first roamed the lands although not completely. They have adapted to many aspects of modern life including motor vehicles to move around where possible. Just as the technologies of Bedouin tribes have changed, so have the concept of a home which can be a tent, a stone building or even the desert land (30). They are ethnically Arab, and most are now Muslim. Relationships between other ethnic Arabs and Bedouins has always been mixed. They have sometimes suffered horrifically at the hands of national governments while some Arab people perceive the Bedouin as “pure” or romantic much in the same way that other countries romanticize other lost traditions such as the Roma travelers of Eastern Europe or the Amazonian “lost” tribes who have only had limited contact with the outside world. At the end of the 20 th century, less than 1% of the population in countries where Bedouins still roam maintain that lifestyle.

The Bedouin are not the only nomadic or semi-nomadic life. The Marsh Arabs so brutally oppressed by Saddam Hussein in the early 1990s were semi-nomadic, as are some elements of the Kurdish peoples of southeastern Turkey. Some aspects of Mongolian life in the Gobi Desert, and the Sami people of northern Scandinavia and the arctic islands such as Svalbard continue in their semi-nomadic traditions. Like their counterparts to the south, they too are increasingly moving to permanent settlement.

Desert Topographical Functions

Deserts are vital in many ways ecologically. Firstly, they are home to 17% of the human population who have adapted or adapted to the various desert biomes. Water is vital to life and although they lack this necessary resource, their unique ecosystems provide survival and resources for the plant and animal species that live there (31). Deserts carry out vital planetary environmental functions too. Most of these species have adapted to the uniquely harsh environments of both hot and cold deserts and everything in between. Often, these species do not exist in other types of environment. For that reason alone, it’s necessary to conserve desert spaces and to avoid encroaching on them unnecessarily or altering them for other purposes. They are home to various livestock such as camels, goats, and antelope that provide food and livelihood for people. Desert shrubs and trees that produce fruit such as dates, figs, and olives (32), are important food crops globally.

Many are not aware that deserts are a net carbon sink, providing some relief from the increase in greenhouse gases. This will be problematic while carbon emissions continue to increase, and world governments will need to do something about it in the future. The discovery was made when researching bacteria in the desert. Research suggests that bacteria located in massive aquifers beneath the sand and in the sands itself, are capturing carbon from the air. In theory, the aquifers could hold more than the entire global population of plant material at present at 20 billion metric tons (or 22 billion imperial/US tons) (33).

Finally, deserts, due to their location, are important sources of generating renewable energy. It is no coincidence that the world’s solar arrays are located in the hottest places on the planet. Smaller solar panels convert light into energy, but the large arrays in the deserts work differently. They harness the heat and use mirrors to reflect and divert into the array, to generate much more energy per square foot. Deserts are also useful sources of wind power. There are always desert winds, but at certain times of the year wind is much higher which can also generate energy (34).

Leisure and Tourism

Deserts attract millions of visitors every year. From the deserts of the Middle East and North Africa where visitors may see the Great Pyramids of Giza in Egypt, to Jordan’s city of Petra, Carthage and others, they are great places to see well-preserved archaeological ruins of the past. Here in the USA, there are plenty of other examples of ancient cultures in the desert. The Chaco culture, Pueblo peoples such as the Anasazi and Hohokum lived in the deserts of modern New Mexico, Utah, and Arizona. The Anasazi houses at Mesa Verde is incredible site, as is the Casa Grande monument in Arizona, built by the Hohokum Culture. In South America there are many sites and artefacts recovered from the Atacama. In short, people have settled deserts for hundreds of thousands of years and the dry nature makes such remains attractive to visitors (35).

Not that culture and history is the limit of desert leisure and tourism. Some visit to see natural wonders such as Grand Canyon in Arizona, the great salt plains of the Atacama Desert or take a 4×4 vehicle or a hot air balloon ride across the sand dunes of the Arabian deserts. The semi-arid Monegros Desert in northeastern Spain plays host to an annual music festival called Monegros Desert Festival while the cold and arid landscapes of Greenland and Iceland draw visitors from all over the globe. The wide-open spaces of deserts can host great numbers of people without putting too much of a strain on local infrastructure. Despite the strain that tourism can put on these delicate ecosystems, they are providing much-needed money and jobs to areas. Ecotourism is helping developing nations especially find ways of preserving those landscapes (36) when historically, deserts have been neglected both in the conservation debate, and the funding and planning.
