Over 77% of Earth’s Land Becomes Drier in Last 30 Years, Warns UN Report
A new United Nations (UN) report has raised alarms about the increasing dryness of the Earth’s land, with over 77% of the world’s land experiencing drier conditions over the past 30 years. This alarming trend, largely attributed to human activities and climate change, poses significant challenges to the planet’s ecosystems, agriculture, and the livelihoods of billions of people worldwide.
UN Report Highlights Widespread Drying of the Earth’s Land
The UN’s Intergovernmental Panel on Climate Change (IPCC) published a comprehensive study revealing that the majority of the Earth’s land has become drier between 1991 and 2021. This trend is directly linked to human-induced climate change, particularly the increase in greenhouse gases. As the atmosphere warms, it intensifies the water cycle, leading to more extreme weather patterns, including longer droughts and reduced rainfall.
These changes are especially evident in arid and semi-arid regions, such as parts of the Mediterranean, Southern Africa, and South Asia, which have seen the most pronounced drying effects. The report warns that this trend could worsen unless immediate action is taken to curb greenhouse gas emissions and promote sustainable land management practices.
Impact on Agriculture and Ecosystems
The dryness of land is having a profound effect on global agriculture, as crops require adequate water supply for growth. As land becomes drier, the risk of crop failure increases, threatening food security, especially in regions already struggling with poverty. Moreover, the decline in soil moisture affects biodiversity, making it harder for plant and animal species to thrive.
In addition to agricultural loss, drier lands contribute to the intensification of wildfires, which have become more frequent and devastating in recent years. These fires further contribute to the degradation of ecosystems and exacerbate the impact of climate change.
Why this News is Important
Escalating Climate Change Concerns
This UN report sheds light on the global escalation of climate change impacts. The fact that over 77% of the Earth’s land has become drier over the past three decades is a clear indication that climate change is not a distant threat but a current reality. The significant role of human activities in contributing to these changes, particularly through the emission of greenhouse gases, highlights the urgency of adopting more sustainable practices.
Urgent Need for Global Action
This study underscores the need for immediate global action to address climate change. Countries must implement robust policies to reduce emissions and invest in climate adaptation strategies. This includes improving water management systems, adopting climate-resilient agricultural practices, and protecting natural ecosystems that help mitigate the effects of land degradation.
Implications for Future Generations
As the effects of land drying intensify, future generations will likely face more severe challenges related to water scarcity, food insecurity, and environmental degradation. The report serves as a crucial reminder that we must act now to preserve the planet’s resources for the benefit of future generations.
Historical Context: Background Information Related to the News Story
Climate Change and Land Degradation
Land degradation has been a growing concern for decades. Historically, human activities such as deforestation, unsustainable farming practices, and industrialization have led to a gradual deterioration of the Earth’s natural landscapes. However, it was not until the late 20th century that the scientific community began to fully recognize the extent of human influence on climate patterns and land use.
The issue of land drying has been particularly exacerbated by climate change, which became a central focus of global discussions in the 1990s. The UN Framework Convention on Climate Change (UNFCCC), established in 1992, sought to combat global warming by reducing greenhouse gas emissions and mitigating its impacts.
Global Efforts to Tackle the Crisis
Various global initiatives have been launched to combat land degradation, such as the United Nations Convention to Combat Desertification (UNCCD), established in 1994. The UNCCD aims to address desertification, land degradation, and drought through sustainable land management. The 2015 Paris Agreement also sought to limit global warming and reduce climate change impacts, but the recent UN report shows that progress has been slow, and urgent measures are needed to reverse the damage.

Important FAQs for Students from this News
Q1: What is the main finding of the UN report on land dryness?
A1: The UN report reveals that over 77% of the Earth’s land has become drier over the past 30 years due to human-induced climate change and its impacts, such as rising greenhouse gas emissions and altered rainfall patterns.
Q2: Which regions are most affected by land dryness?
A2: Regions most affected by land dryness include Southern Africa, South Asia, and the Mediterranean, which have experienced the most pronounced drying effects, impacting agriculture and ecosystems.
Q3: How does land dryness affect agriculture?
A3: Land dryness reduces soil moisture, increasing the risk of crop failures, leading to food insecurity, particularly in vulnerable regions that rely on rain-fed agriculture.
Q4: What are the environmental impacts of drying land?
A4: Drying land contributes to biodiversity loss, intensification of wildfires, and ecosystem degradation, making it harder for plant and animal species to survive.
Q5: What actions are needed to address the issue of land dryness?
A5: Immediate actions include reducing greenhouse gas emissions, adopting sustainable land management practices, improving water management, and investing in climate adaptation strategies to mitigate the impact of land degradation.
