World Day to Combat Desertification and Drought 2026: Protecting Land for a Sustainable Future
By Dr. Md. Mahtab Hossain Mazed
Every year on 17 June, the world observes the World Day to Combat Desertification and Drought. Initiated by the United Nations, the primary objective of this day is to raise awareness about the devastating impacts of drought, land degradation, and desertification, and to promote sustainable land management to ensure a safe, green, and livable planet for future generations. As climate change increasingly affects human life, agriculture, economies, and ecosystems, the significance of this observance continues to grow.
Land is one of the fundamental resources that supports human existence, food production, biodiversity conservation, and economic development. Yet today, this invaluable resource faces multiple threats. Deforestation, excessive use of chemicals, unplanned urbanization, industrialization, and climate change are causing vast areas of land worldwide to lose their productivity. As a result, food security, water security, and ecological balance are under serious threat.
What Are Drought and Desertification?
Drought refers to a prolonged period of below-normal rainfall that results in water shortages. Desertification, on the other hand, is a process through which fertile land gradually loses its productivity and becomes barren.
Desertification does not simply mean the expansion of deserts. It includes:
- Declining soil fertility
- Reduced agricultural productivity
- Destruction of forests and vegetation
- Loss of biodiversity
- Shrinking water resources
- Disruption of ecological balance
- Therefore, desertification is an environmental, economic, and social crisis that directly affects human well-being.
- Global Reality and Alarming Statistics
According to various United Nations reports, nearly 40 percent of the world's land is currently degraded to some extent, affecting approximately 3.2 billion people. Every year, nearly 100 million hectares of land lose their productive capacity, negatively impacting food production and livelihoods.
Around 70 percent of the world's freshwater resources are used in agriculture. Consequently, the agricultural sector suffers the most when drought occurs.
UN data indicate that since 2000, the frequency and intensity of droughts have increased by nearly 30 percent. If climate change continues unabated, many regions of the world may become significantly drier by 2050.
Experts warn that if current trends persist, millions of people may be displaced due to environmental degradation in the future. Thus, drought and desertification are not merely environmental concerns; they are also linked to global security, poverty, and migration crises.
Climate Change and Drought.
One of the major drivers of increasing droughts is climate change. Rising global temperatures are altering natural rainfall patterns, resulting in excessive rainfall in some areas and prolonged droughts in others.
Higher temperatures accelerate soil moisture loss, dry up rivers, canals, and water bodies, disrupt agricultural production, and increase water demand. Combined with heatwaves, drought poses severe risks to public health.
Major Causes of Drought and Desertification
Climate Change
Global warming is changing rainfall patterns and increasing prolonged droughts.
Deforestation
Trees help retain soil moisture. Uncontrolled deforestation accelerates land degradation.
Excessive Groundwater Extraction
Unplanned extraction of groundwater is causing water tables to decline in many regions.
Unsustainable Agricultural Practices
Excessive use of chemical fertilizers and pesticides, along with repeated cultivation of the same crop, degrades soil quality.
Urbanization and Industrialization
Conversion of agricultural land and wetlands into industrial and residential areas disrupts ecological balance.
The Bangladesh Perspective
Although Bangladesh is widely recognized as a flood-prone country, drought risks are also increasing. Districts such as Rajshahi, Naogaon, Chapainawabganj, Natore, Joypurhat, and Dinajpur are experiencing seasonal droughts as a growing reality.
In the Barind region, groundwater levels continue to decline. Irregular rainfall, heatwaves, and irrigation-dependent agriculture have intensified the crisis. During the dry season, farmers often rely heavily on irrigation, increasing production costs.
Experts caution that climate change may further expand drought-prone areas in Bangladesh in the future.
Impact on Food Security
The most significant impact of drought and desertification is on food production.
Reduced crop yields
Increased irrigation costs
Rising food prices
Limited access to food for vulnerable populations
Higher risk of malnutrition
As the global population continues to grow, protecting land productivity is essential for ensuring food security.
Economic Consequences
Land degradation and drought cause substantial economic losses every year.
As a result:
Farmers' incomes decline
Agro-based industries suffer
Employment opportunities decrease
Poverty rates increase
Food import costs rise
In agriculture-dependent economies such as Bangladesh, these impacts are particularly severe.
Public Health and Social Impacts
Drought and desertification also have significant consequences for public health.
Shortage of safe drinking water
Increased risk of waterborne diseases
Rise in heat-related illnesses
Food shortages and malnutrition
Increased stress and anxiety
Livelihood challenges often force people to migrate from rural areas to cities, creating additional social and urban pressures.
Environmental and Biodiversity Loss
Land degradation leads to:
Shrinking forest cover
Destruction of wildlife habitats
Decline in soil organic matter
Reduced carbon sequestration capacity
Ecological imbalance
These effects further accelerate climate change.
Sustainable Development Goals (SDGs) and Land Protection
One of the key objectives of the United Nations Sustainable Development Goals (SDGs) is to prevent land degradation and restore ecological balance. In particular, SDG 15: Life on Land emphasizes the conservation of land, forests, and biodiversity.
Without protecting land resources, achieving sustainable development, food security, and climate resilience will be impossible.
The Role of Youth
Young people have a vital role to play in combating drought and desertification.
They can:
Participate in tree-planting initiatives
Promote water conservation awareness
Lead environmental movements
Reduce plastic pollution
Adopt environmentally friendly lifestyles
What Needs to Be Done
Addressing drought and desertification requires coordinated action.
1. Large-Scale Tree Plantation
Plant indigenous tree species
Prevent deforestation
Expand social forestry programs
2. Sustainable Agriculture
Cultivate low-water-demand crops
Promote organic farming
Practice crop rotation
Use modern irrigation technologies
3. Water Conservation
Harvest rainwater
Restore canals, wetlands, and reservoirs
Prevent groundwater wastage
4. Sustainable Land Management
Protect agricultural land
Ensure planned land use
Stop illegal encroachment and land filling
5. Public Awareness
Strengthen environmental education
Increase media campaigns
Engage local communities
Islam and Environmental Protection
Islam places great emphasis on environmental stewardship. The Holy Qur'an instructs believers not to spread corruption and destruction on Earth. The Prophet Muhammad (peace be upon him) described tree planting as a virtuous act that brings continuous rewards. Avoiding water wastage, preserving natural resources, and maintaining ecological balance are all important teachings of Islam.
Therefore, protecting land, forests, and water is not only an environmental responsibility but also a moral and religious obligation.
Conclusion
The World Day to Combat Desertification and Drought 2026 reminds us that land and water resources are not unlimited. Today's negligence may lead to tomorrow's severe crises. Addressing drought and desertification requires the collective efforts of governments, local administrations, farmers, researchers, educational institutions, media organizations, and the general public.
Through environmentally responsible development, sustainable agriculture, water conservation, and extensive tree plantation, we can leave behind a greener, more fertile, and more livable world for future generations. If land survives, agriculture survives; if agriculture survives, people survive; and only then can sustainable development and a prosperous future be secured.
