Affects millions of people worldwide
Urgent action needed to combat desertification

Desertification is a serious global problem that requires concerted efforts from governments, organizations, and individuals to address its causes and mitigate its impacts.

Land degradation in drylands

Land degradation in drylands is the main cause of desertification. Drylands are regions that receive less than 250 millimeters of precipitation per year. They cover about 40% of the Earth's land surface and are home to over 2 billion people.

Deforestation:
The clearing of forests for agriculture, logging, or other purposes can lead to land degradation in drylands. Trees help to hold the soil in place and prevent erosion. When trees are removed, the soil is more vulnerable to being blown away by the wind or washed away by water.
Overgrazing:
When livestock are allowed to graze on land for too long or in too high numbers, it can lead to overgrazing. This can damage the vegetation and expose the soil to erosion. Overgrazing can also compact the soil, making it less able to absorb water.
Poor agricultural practices:
Unsustainable agricultural practices, such as using too much water or fertilizer, can also lead to land degradation in drylands. These practices can damage the soil structure and make it more susceptible to erosion. They can also pollute water sources and harm wildlife.
Climate change:
Climate change is also a major factor contributing to land degradation in drylands. Rising temperatures and changes in precipitation patterns are making it more difficult for vegetation to survive in these regions. Climate change is also leading to more frequent and severe droughts, which can further degrade the land.

Land degradation in drylands is a serious problem that is threatening the livelihoods of millions of people. It is also a major contributor to climate change, as degraded land releases carbon dioxide into the atmosphere. Urgent action is needed to address the causes of land degradation in drylands and to restore these fragile ecosystems.

Caused by climate change and human activities

Desertification is caused by a combination of climate change and human activities. Climate change is making drylands hotter and drier, which makes it more difficult for vegetation to survive. Human activities, such as deforestation, overgrazing, and poor agricultural practices, are also major contributors to desertification.

Climate change:
Climate change is a major driver of desertification. Rising temperatures and changes in precipitation patterns are making it more difficult for vegetation to survive in drylands. Climate change is also leading to more frequent and severe droughts, which can further degrade the land.
Deforestation:
The clearing of forests for agriculture, logging, or other purposes can lead to desertification. Trees help to hold the soil in place and prevent erosion. When trees are removed, the soil is more vulnerable to being blown away by the wind or washed away by water. Deforestation can also reduce the amount of rainfall in an area, making it even drier.
Overgrazing:
When livestock are allowed to graze on land for too long or in too high numbers, it can lead to overgrazing. This can damage the vegetation and expose the soil to erosion. Overgrazing can also compact the soil, making it less able to absorb water.
Poor agricultural practices:
Unsustainable agricultural practices, such as using too much water or fertilizer, can also lead to desertification. These practices can damage the soil structure and make it more susceptible to erosion. They can also pollute water sources and harm wildlife.

Desertification is a serious problem that is threatening the livelihoods of millions of people around the world. It is also a major contributor to climate change, as degraded land releases carbon dioxide into the atmosphere. Urgent action is needed to address the causes of desertification and to restore these fragile ecosystems.

Leads to loss of biodiversity

Desertification can lead to a significant loss of biodiversity. Drylands are home to a wide variety of plants and animals that are adapted to the harsh conditions. However, when these ecosystems are degraded, many species are unable to survive.

Habitat loss:
Desertification can lead to the loss of habitat for many plants and animals. When land is degraded, it becomes less hospitable to vegetation, which in turn reduces the food and shelter available for animals. This can lead to a decline in biodiversity, as many species are unable to adapt to the changing conditions.
Reduced water availability:
Desertification can also lead to a reduction in water availability. This can make it difficult for plants and animals to survive. Many species are unable to tolerate the high temperatures and low humidity that are common in deserts. As a result, they may be forced to migrate to new areas or they may simply die.
Pollution:
Desertification can also lead to an increase in pollution. When land is degraded, it is more susceptible to erosion. This can lead to the release of harmful chemicals and pollutants into the environment. These pollutants can harm plants and animals, and they can also contaminate water sources.
Climate change:
Desertification can also contribute to climate change. Degraded land releases carbon dioxide into the atmosphere, which is a greenhouse gas. Greenhouse gases trap heat in the atmosphere, which leads to an increase in global temperatures. This can further exacerbate desertification, as it makes drylands even hotter and drier.

The loss of biodiversity due to desertification is a serious problem. Biodiversity is essential for the health of our planet. It provides us with food, medicine, and other resources. It also helps to regulate the climate and protect us from natural disasters. Urgent action is needed to address the causes of desertification and to restore these fragile ecosystems.

Decreases agricultural productivity

Desertification can have a devastating impact on agricultural productivity. Drylands are home to some of the most vulnerable agricultural systems in the world. When these ecosystems are degraded, it becomes increasingly difficult to grow crops and raise livestock.

Soil degradation:
Desertification can lead to soil degradation, which makes it difficult for plants to grow. Soil degradation can be caused by a number of factors, including erosion, salinization, and nutrient depletion. When soil is degraded, it is less able to hold water and nutrients, which makes it difficult for plants to survive.
Water scarcity:
Desertification can also lead to water scarcity. When land is degraded, it is less able to absorb and store water. This can lead to a decline in groundwater levels and a decrease in the amount of water available for irrigation. Water scarcity can make it difficult for farmers to grow crops and raise livestock.
Climate change:
Climate change is also a major factor contributing to decreased agricultural productivity in drylands. Rising temperatures and changes in precipitation patterns are making it more difficult for crops to grow. Climate change is also leading to more frequent and severe droughts, which can further reduce agricultural productivity.
Loss of biodiversity:
Desertification can also lead to a loss of biodiversity, which can have a negative impact on agricultural productivity. Biodiversity is essential for the health of ecosystems. It provides a variety of benefits, including pollination, pest control, and nutrient cycling. When biodiversity is lost, these benefits are lost as well, which can lead to a decline in agricultural productivity.

The decrease in agricultural productivity due to desertification is a serious problem. Agriculture is a major source of food and income for people in drylands. When agricultural productivity declines, it can lead to food insecurity and poverty. Urgent action is needed to address the causes of desertification and to restore these fragile ecosystems.

Contributes to poverty and food insecurity

Desertification can have a devastating impact on poverty and food insecurity. Drylands are home to some of the poorest and most food-insecure people in the world. When these ecosystems are degraded, it becomes increasingly difficult for people to make a living and to feed their families.

There are a number of ways in which desertification can contribute to poverty and food insecurity:

Loss of agricultural productivity: Desertification can lead to a decline in agricultural productivity, which can make it difficult for farmers to produce enough food to feed their families and to generate income.
Loss of livestock: Desertification can also lead to a loss of livestock, which are a valuable source of food, income, and transportation for many people in drylands. When livestock die or are lost, it can have a devastating impact on the livelihoods of herders and their families.
Migration: Desertification can also force people to migrate from their homes in search of food and water. This can lead to the loss of traditional livelihoods and social networks, and it can also increase the risk of conflict and instability.
Increased vulnerability to climate change: Desertification can also make people more vulnerable to the impacts of climate change. Degraded land is less able to absorb and store water, which can lead to more frequent and severe droughts. Climate change is also leading to rising temperatures, which can make it difficult for people to grow crops and raise livestock.

Desertification is a serious problem that is threatening the livelihoods and food security of millions of people around the world. Urgent action is needed to address the causes of desertification and to restore these fragile ecosystems.

In addition to the points mentioned above, desertification can also contribute to poverty and food insecurity in the following ways:

Reduced access to water: Desertification can lead to a reduction in water availability, which can make it difficult for people to access clean drinking water. This can lead to health problems and can also make it difficult for people to grow crops and raise livestock.
Loss of biodiversity: Desertification can also lead to a loss of biodiversity, which can have a negative impact on food security. Biodiversity is essential for the health of ecosystems. It provides a variety of benefits, including pollination, pest control, and nutrient cycling. When biodiversity is lost, these benefits are lost as well, which can lead to a decline in agricultural productivity and an increase in food insecurity.
