These deserts are characterized by low rainfall, high temperatures, and unique ecosystems. It’s worth noting that there are also many smaller deserts and desert-like regions around the world, which can further complicate the count.

Defining Deserts: Criteria and Characteristics

What is a desert?

A desert is a landscape that is characterized by a lack of water and extreme temperatures. This arid environment is defined by its limited precipitation, which is often less than 250 millimeters per year. Deserts are typically classified based on their location, climate, and vegetation.

There are several criteria that are used to define a desert, including:

  • Low Precipitation: Deserts are known for their limited precipitation, which can be as low as 250 millimeters per year or less. This lack of water makes it difficult for plants and animals to survive in these environments.
  • High Temperatures: Deserts are known for their extreme temperatures, with some reaching over 50 degrees Celsius during the day and dropping to freezing at night. These temperatures can make it difficult for living organisms to survive in these environments.
  • Arid Conditions: Deserts are characterized by their arid conditions, with little to no moisture in the air. This lack of moisture can make it difficult for plants and animals to obtain the water they need to survive.
  • Vegetation: Deserts can be classified based on their vegetation, with some having sparse vegetation and others having none at all. The type of vegetation found in a desert can provide clues about the climate and other environmental factors.

In summary, a desert is a landscape that is characterized by its lack of water, extreme temperatures, arid conditions, and limited vegetation. These environments can be found in various locations around the world and can range from sparse vegetation to complete barrenness.

Types of deserts

Deserts are defined by their aridity, or lack of moisture. However, not all deserts are created equal. There are several different types of deserts, each with its own unique characteristics. Here are some of the most common types of deserts:

  • Hot Deserts: These deserts are characterized by high temperatures and low humidity. They are found in areas near the equator and are often associated with sandy dunes. The two most well-known hot deserts are the Sahara in Africa and the Gobi in Asia.
  • Cold Deserts: These deserts are found in high-altitude regions and are characterized by low temperatures and strong winds. The Gobi Desert is also considered a cold desert.
  • Coastal Deserts: These deserts are found along the coast and are characterized by their high levels of salinity. The Atacama Desert in Chile is one of the driest coastal deserts in the world.
  • Inland Deserts: These deserts are found in interior regions and are characterized by their high levels of aridity. The Great Basin Desert in the United States is an example of an inland desert.
  • Polar Deserts: These deserts are found in the polar regions and are characterized by their cold temperatures and strong winds. The McMurdo Dry Valleys in Antarctica are considered a polar desert.

Understanding the different types of deserts is crucial for accurately defining how many deserts exist on Earth. While some sources may group all deserts together, others may count each type of desert as a separate entity. As we continue to explore the mystery of how many deserts exist on Earth, it’s important to keep these different types of deserts in mind.

Climate and geography

Deserts are arid regions characterized by low precipitation, high evaporation, and extreme temperatures. They are often found in areas near the equator or in the middle of continents, where the climate is dry and hot. Deserts can be classified based on their geographical location, climate, and vegetation.

One way to classify deserts is by their location. There are four main types of deserts:

  1. Coastal deserts: These deserts are located near the coast and are characterized by strong winds that bring in moisture from the ocean. The Atacama Desert in Chile and the Namib Desert in Africa are examples of coastal deserts.
  2. Continental deserts: These deserts are found in the interior of continents and are characterized by high temperatures and low precipitation. The Gobi Desert in Asia and the Sahara Desert in Africa are examples of continental deserts.
  3. Deserts of cold regions: These deserts are found in cold regions, such as the polar regions and high-altitude regions. They are characterized by low temperatures and strong winds. The McMurdo Dry Valleys in Antarctica and the Gobi Altai Mountains in Mongolia are examples of deserts of cold regions.
  4. Deserts of monsoon regions: These deserts are found in areas where there is a seasonal change in the wind direction. They are characterized by heavy rainfall during the monsoon season and dry conditions during the rest of the year. The Thar Desert in India and the Sonoran Desert in the United States are examples of deserts of monsoon regions.

Another way to classify deserts is by their climate. Deserts can be classified as hot or cold based on their average temperature. Hot deserts have high temperatures year-round, while cold deserts have low temperatures year-round. Hot deserts are further divided into two categories: subtropical and tropical. Subtropical deserts are found near the subtropics and are characterized by hot summers and mild winters. Tropical deserts are found near the equator and are characterized by high temperatures and high humidity. Cold deserts are further divided into two categories: polar and alpine. Polar deserts are found in polar regions and are characterized by low temperatures and strong winds. Alpine deserts are found in high-altitude regions and are characterized by low temperatures and strong winds.

Finally, deserts can be classified based on their vegetation. Deserts can be classified as having either a shrub or grassland vegetation. Shrub deserts are characterized by shrubs and small trees, while grassland deserts are characterized by grasses and herbs.

In conclusion, deserts are defined by their climate and geography, and can be classified based on their location, climate, and vegetation. Understanding the different types of deserts can help us better understand the geography and climate of our planet.

The Official Count: Deserts According to the UN

Key takeaway: Deserts are arid regions characterized by low precipitation, high evaporation, and extreme temperatures. They can be classified based on their location, climate, and vegetation. The United Nations (UN) provides a standardized definition of deserts, which is widely accepted by scientists and researchers. According to the UN, there are 17 official deserts on Earth, recognized based on their specific geographical features and environmental characteristics. However, there are still some disputed areas and uncertainties regarding the exact number of deserts, with some experts arguing that certain regions should be considered as separate deserts, while others claim that some areas are not truly deserts but rather drylands or arid regions. The existence of non-official deserts expands the definition of deserts beyond their traditional boundaries, highlighting the diverse geographical features and ecosystems found across the globe. Underestimated deserts have been revealed to be rich in biodiversity and important to the global ecosystem. Human activities have had a profound impact on the environment, leading to the formation of new deserts in various parts of the world. Climate change is causing an increase in temperatures and changes in precipitation patterns, leading to the expansion of existing deserts and the formation of new ones. The world’s deserts are expanding at an alarming rate, transforming landscapes and disrupting ecosystems. It is crucial to understand their dynamics and develop strategies to mitigate their impact on both the environment and human societies.

United Nations definition of deserts

The United Nations (UN) provides a standardized definition of deserts, which is widely accepted by scientists and researchers. According to the UN, a desert is a “landscape class characterized by a significant and long-lasting imbalance of moisture supply and demand, manifested as aridity and resulting in extensive areas with low plant cover and sparse vegetation.” This definition considers not only the amount of rainfall but also the availability of water and the climate’s aridity.

Under this definition, deserts are divided into five categories based on their aridity:

  1. Hyper-arid deserts: These deserts have an annual precipitation of less than 25 mm (1 in). They are typically found in the tropics and subtropics, where atmospheric evaporation is high, and precipitation is low. Examples include the Atacama Desert in Chile and the Namib Desert in Namibia.
  2. Arid deserts: These deserts have an annual precipitation of 25 to 200 mm (1 to 8 in). They are found in both the subtropics and mid-latitudes, with the majority of the precipitation falling in the form of rain during infrequent and intense storms. The Gobi Desert in Mongolia and the Sonoran Desert in the United States are examples of arid deserts.
  3. Semi-arid deserts: These deserts have an annual precipitation of 200 to 600 mm (8 to 24 in). They are characterized by irregular rainfall patterns, with long dry periods followed by occasional heavy rainfall. The Kalahari Desert in Africa and the Great Basin Desert in the United States are examples of semi-arid deserts.
  4. Subtropical deserts: These deserts have an annual precipitation of 600 to 1,500 mm (24 to 60 in). They are typically found in coastal areas near subtropical regions, where moisture-laden trade winds meet cold ocean currents, resulting in limited precipitation. The Atacama Desert in Chile and the Arabian Desert in Saudi Arabia are examples of subtropical deserts.
  5. Tropical wet and dry deserts: These deserts have an annual precipitation of 1,500 to 2,500 mm (60 to 100 in). They are found in tropical regions where heavy rainfall is concentrated in a short period during the monsoon season, resulting in dry periods that can last for several months. The Indian Desert in India and the Sudanian Savanna in West Africa are examples of tropical wet and dry deserts.

The UN’s definition of deserts is crucial for understanding the global distribution and characteristics of these unique ecosystems.

Counting the official deserts

According to the United Nations (UN), there are 17 official deserts on Earth. These deserts are recognized based on their specific geographical features and environmental characteristics. To be classified as an official desert, a region must meet certain criteria, such as having low precipitation, high evaporation rates, and extreme temperatures. The UN defines deserts as “arid or semi-arid regions with sparse vegetation and a limited number of animal and human populations.”

The official deserts recognized by the UN are spread across various continents, including Africa, Asia, Europe, North America, and South America. These deserts vary in size, with some covering millions of square kilometers, while others are much smaller. The largest official desert is the Antarctic Desert, which covers most of the Antarctic continent, while the smallest is the Great Victoria Desert in Australia, which is only about 347,000 square kilometers in size.

The UN’s classification system helps to standardize the way deserts are defined and studied, allowing for more accurate comparisons and analyses of these unique ecosystems. However, it is important to note that this official count does not include all regions that could be considered deserts based on local definitions or cultural perspectives. Some regions may be classified as deserts by local communities or researchers, but not yet recognized by the UN. Additionally, some areas that are not officially classified as deserts may still exhibit desert-like characteristics due to their arid conditions and limited vegetation.

In conclusion, the UN’s official count of 17 deserts provides a standardized framework for recognizing and studying these unique ecosystems. However, it is important to acknowledge that this count may not be exhaustive, and there may be other regions that could be considered deserts based on various definitions and perspectives.

Disputed areas and uncertainties

While the United Nations (UN) recognizes ten major deserts on Earth, there are still some disputed areas and uncertainties regarding the exact number of deserts. Some experts argue that certain regions should be considered as separate deserts, while others claim that some areas are not truly deserts but rather drylands or arid regions.

One of the main sources of confusion is the definition of a desert itself. According to the UN, a desert is a region that receives less than 250 millimeters (9.8 inches) of annual precipitation. However, some scientists argue that this definition is too narrow and does not take into account other factors such as temperature, topography, and vegetation.

Another issue is the lack of consistent data collection and monitoring in many regions. Some areas, particularly in developing countries, have limited resources for scientific research and monitoring, making it difficult to accurately determine the level of aridity and desertification.

Furthermore, there are ongoing debates about the classification of certain regions, such as the Polar Desert in Antarctica, which some experts argue should be considered a desert due to its extreme cold and dry conditions, while others claim that it is not a true desert due to its unique geography and climate.

Despite these uncertainties, scientists continue to work towards a more accurate understanding of the world’s deserts and their impact on the global environment.

Non-official deserts

The term “non-official deserts” refers to regions that may not be officially recognized as deserts but exhibit many of the characteristics typically associated with this geographical feature. These areas often share the same arid climate, extreme temperatures, and limited vegetation coverage found in true deserts. This section aims to explore these non-official deserts and the factors that contribute to their formation.

  • Tundra regions: The tundra, a treeless plain found in Arctic and alpine climates, shares some similarities with deserts. It has a cold, dry climate with low precipitation, leading to a limited vegetation cover. Although the tundra’s permafrost soil and unique ecosystem set it apart from true deserts, it is still considered a non-official desert due to its harsh, arid conditions.
  • Dry grasslands: Found primarily in Africa and South America, dry grasslands exhibit a mosaic of grasses, shrubs, and trees. These regions experience seasonal droughts and have limited water resources, which are characteristic of deserts. While not classified as deserts, they still share many desert-like features, such as the dependence on drought-resistant vegetation and the potential for sand dunes formation.
  • Mediterranean regions: Mediterranean climates, characterized by warm, dry summers and mild, wet winters, can be considered non-official deserts. These regions have limited rainfall, leading to the development of arid and semi-arid habitats. They support a unique mix of vegetation, including cacti, succulents, and other drought-tolerant plants, often found in desert ecosystems.
  • Desertification: In some cases, areas that were once not classified as deserts can transform into desert-like landscapes due to human activities or climate change. This process, known as desertification, can cause the degradation of soil, vegetation, and water resources, turning once-fertile lands into barren, arid regions. These newly formed deserts are considered non-official deserts, as they exhibit the same environmental conditions as true deserts.

The existence of non-official deserts expands the definition of deserts beyond their traditional boundaries, highlighting the diverse geographical features and ecosystems found across the globe. By recognizing these regions as non-official deserts, scientists and conservationists can better understand the challenges and opportunities associated with managing these unique environments.

The Expanding Frontier: New Deserts in the Making

Human impact on desert formation

Human activities have had a profound impact on the environment, leading to the formation of new deserts in various parts of the world. Here are some ways in which human activities contribute to desert formation:

  • Land use changes: The conversion of natural vegetation cover to agricultural land has led to the degradation of soil and reduced infiltration rates, resulting in the formation of deserts.
  • Overgrazing: Overgrazing by livestock can lead to soil erosion and the destruction of vegetation, which in turn leads to desertification.
  • Deforestation: Deforestation can cause soil erosion, leading to the loss of fertile land and the formation of deserts.
  • Climate change: Climate change is causing an increase in temperatures and changes in precipitation patterns, leading to the expansion of existing deserts and the formation of new ones.
  • Water management: Human activities such as the construction of dams and canals can alter water flow patterns, leading to the formation of deserts.

In conclusion, human activities have played a significant role in the formation of new deserts on Earth. It is important for individuals and governments to take action to mitigate these activities and protect the environment from further degradation.

Climate change and desert expansion

As the global climate continues to shift and evolve, the world’s deserts are expanding at an alarming rate. The increasing temperatures and altered precipitation patterns are causing arid and semi-arid regions to grow in size and frequency, transforming landscapes and disrupting ecosystems. This phenomenon is driven by human activities, primarily the burning of fossil fuels, which trap heat in the atmosphere and cause the Earth’s temperature to rise.

Several factors contribute to the expansion of deserts in response to climate change:

  1. Decreased precipitation: As temperatures rise, evaporation increases, leading to a reduction in precipitation in some areas. This creates a positive feedback loop, as less rainfall results in more evaporation, further exacerbating the dryness of the environment.
  2. Changing precipitation patterns: Climate change alters the way precipitation is distributed across the planet. In some regions, this results in more frequent extreme weather events, such as heavy rainfall followed by prolonged droughts, which can lead to desertification.
  3. Increased fire activity: Rising temperatures and decreased precipitation increase the risk of wildfires, which can transform vegetation-rich ecosystems into barren landscapes. These fires also release carbon dioxide and other greenhouse gases into the atmosphere, contributing to further climate change.
  4. Coastal erosion and sea-level rise: As temperatures warm, glaciers and ice sheets are melting, causing sea levels to rise. This not only floods coastal areas but also leads to increased erosion, which can result in the loss of land and the formation of sand dunes, ultimately creating new deserts.

These changes are not only impacting the Earth’s deserts but also altering the balance of ecosystems and affecting the lives of the people who depend on them. As deserts continue to expand, it is crucial to understand their dynamics and develop strategies to mitigate their impact on both the environment and human societies.

Emerging deserts in vulnerable regions

As the global climate continues to shift, certain regions of the world are becoming increasingly vulnerable to desertification. This process, in which fertile land becomes desert, is caused by a variety of factors, including overgrazing, deforestation, and the loss of vegetation due to human activities. In many cases, the desertification of these regions is accelerated by climate change, which alters the natural balance of rainfall and temperature patterns.

One of the most vulnerable regions for desertification is the drylands, which cover much of the world’s land surface and are home to more than two billion people. These regions are particularly susceptible to desertification because they are already prone to drought and have limited water resources. As the global temperature continues to rise, the drylands are becoming increasingly arid, leading to the expansion of existing deserts and the formation of new ones.

In addition to the drylands, other regions that are particularly vulnerable to desertification include coastal areas, which are subject to sea level rise and the erosion of coastal habitats, and mountainous regions, which are vulnerable to soil erosion and the loss of vegetation due to changes in temperature and precipitation patterns. As these regions become more arid, they are at risk of becoming deserts, which can have devastating consequences for the people and wildlife that call them home.

Despite the many challenges posed by desertification, there are steps that can be taken to mitigate its effects and prevent the formation of new deserts. These include measures to reduce greenhouse gas emissions, protect fragile ecosystems, and promote sustainable land use practices. By taking these steps, we can help to ensure that our planet remains a vibrant and diverse place for generations to come.

Deserts are formed by a variety of geological and climatic processes. Some deserts are formed by tectonic activity, such as the Himalayan Desert, which was formed by the collision of the Indian and Eurasian tectonic plates. Other deserts are formed by wind erosion, such as the Loess Plateau in China. Still others are formed by changes in climate, such as the Gobi Desert, which was once a fertile grassland but became a desert due to changes in precipitation patterns.
