What Causes Water Scarcity in Tunisia?

Tunisia, located in North Africa, is a country that suffers from severe water scarcity. The country’s population, which is around 11 million, relies heavily on agriculture, which accounts for more than 15% of the country’s GDP. However, the country’s ability to sustain agricultural practices is severely limited due to the scarcity of water. In this article, we’ll explore the factors that cause water scarcity in Tunisia, and examine what can be done to mitigate its impact on the country’s population.

Water scarcity is a growing concern in Tunisia, a North African country with a semi-arid to arid climate. Despite having relatively high annual rainfall, Tunisia struggles with limited freshwater resources due to a variety of factors. In this essay, we will explore the main causes of water scarcity in Tunisia and discuss potential solutions to this pressing issue.

Tunisia’s Geographical Location

Tunisia is located in the arid region of North Africa, which is characterized by low rainfall and high evaporation rates. The country is bordered by the Mediterranean Sea to the north and the Sahara desert to the south. The lack of rainfall, combined with the high temperatures and arid conditions, makes it challenging for the country to maintain a reliable water supply.

Low Rainfall

Tunisia’s average annual rainfall is around 250 mm per year, which is significantly lower than the world average of 860 mm. The low rainfall is due to its geographical location, which is situated in the arid region of North Africa. The country’s limited water resources are further exacerbated by frequent droughts, which have become more frequent in recent years due to climate change.

High Evaporation Rates

Tunisia’s high temperatures and arid conditions lead to high rates of evaporation, which further reduces the country’s water resources. The country’s average temperature is around 18°C, while the temperature in the desert regions can reach up to 50°C. As a result, water resources are quickly depleted, and the country is forced to rely heavily on groundwater resources.

Overexploitation of Groundwater

Groundwater is the primary source of water in Tunisia, accounting for around 75% of the country’s water supply. The country’s reliance on groundwater has led to overexploitation, which has caused a significant decline in groundwater levels. The overexploitation of groundwater is mainly due to the country’s agricultural practices, which rely heavily on irrigation.

One key takeaway from this article is that water scarcity in Tunisia is primarily caused by the country’s geographical location, low rainfall, high evaporation rates, overexploitation of groundwater, unsustainable agricultural practices, lack of water management, and the impact of climate change. To combat water scarcity, Tunisia needs to implement water management practices, adopt sustainable agricultural practices, treat wastewater, and address climate change by reducing carbon emissions and adapting to its impacts.

Unsustainable Agricultural Practices

Agriculture is the primary user of water in Tunisia, accounting for around 80% of the country’s total water consumption. The country’s agricultural practices are highly inefficient and rely heavily on irrigation, which contributes to the overexploitation of groundwater resources. The overuse of water for irrigation leads to soil degradation, which further exacerbates the country‘s water scarcity.

Lack of Water Management

The overexploitation of groundwater in Tunisia is also due to the lack of water management practices. The country’s water management practices are inefficient and lack proper regulations, which leads to the overuse of water resources. The lack of proper water management practices has led to the depletion of groundwater resources, which has further exacerbated the country’s water scarcity.

Climate Change

Climate change is another significant factor that contributes to water scarcity in Tunisia. The country is experiencing higher temperatures and more frequent droughts, which exacerbate the country’s already limited water resources.

Key takeaway: Tunisia’s water scarcity is caused by the country’s geographical location, low rainfall, high evaporation rates, overexploitation of groundwater due to unsustainable agricultural practices and lack of water management, and climate change. The country can combat water scarcity by implementing proper water management practices, adopting sustainable agricultural practices, treating wastewater, and addressing climate change through reducing carbon emissions and adapting to its impacts.


Climate change has also led to desertification, which is the process of fertile land becoming desert due to climate change and human activities. Desertification has led to a decline in soil quality, which further exacerbates the country‘s water scarcity.

Decrease in Water Quality

Climate change has also led to a decrease in water quality in Tunisia. The increase in temperatures has led to an increase in the growth of algae and other harmful organisms, which make the water unsafe for human consumption.

Solutions to Combat Water Scarcity

To combat water scarcity in Tunisia, there are several solutions that can be implemented. These solutions include:

Water Management

Proper water management practices can help conserve water resources and ensure that water is used efficiently. Water management practices should include the development of regulations to control water use, the implementation of water conservation measures, and the adoption of water-saving technologies.

Sustainable Agriculture

The agricultural sector needs to adopt sustainable practices that reduce water consumption and prevent soil degradation. These practices should include the use of drought-resistant crops, the implementation of efficient irrigation systems, and the adoption of agroforestry practices.

Water Treatment

The treatment of wastewater and the re-use of treated water can help reduce the demand for freshwater resources. Wastewater treatment facilities should be developed and implemented to ensure that wastewater is treated properly and can be re-used for non-potable purposes.

Climate Change Mitigation

Addressing climate change is crucial to combat water scarcity in Tunisia. The country needs to take measures to reduce its carbon emissions and implement strategies to adapt to the impacts of climate change.

FAQs – What causes water scarcity in Tunisia?

What is water scarcity?

Water scarcity refers to when the demand for water exceeds the available supply in a particular region. This can happen due to a variety of reasons, such as climate change, overconsumption, over-extraction, and poor management of water resources.

Why is water scarcity a problem in Tunisia?

Tunisia is one of the most water-scarce countries in the world, with an annual renewable freshwater supply of less than 500 cubic meters per capita. This scarcity is compounded by a growing population, climate change, and a high demand for water for agriculture, industry, and domestic use. Tunisia is also vulnerable to droughts and irregular rainfall patterns, which further exacerbate the problem.

What are the main causes of water scarcity in Tunisia?

The main causes of water scarcity in Tunisia are over-extraction of groundwater, poor water resource management, and climate change. Over-extraction of groundwater through unregulated drilling of wells and pumps for irrigation, drinking water, and industrial use contributes to the depletion of aquifers and saltwater intrusion in coastal areas. Poor water resource management, such as inefficient irrigation practices, lack of investment in water infrastructure, and inadequate monitoring, also exacerbates the problem. Climate change has led to reduced rainfall, higher temperatures, and increased evaporation rates, further reducing the availability of freshwater resources.

How does water scarcity impact Tunisians?

Water scarcity has significant social, economic, and environmental impacts on Tunisians. It affects farmers, who rely on irrigation for their crops, and industries, which need water to operate. It also affects households, who have limited access to clean water for drinking, cooking, and sanitation. Women and children often bear the brunt of water scarcity, as they are responsible for collecting water from distant sources. The environment is also impacted by water scarcity, as it can lead to soil erosion, desertification, and wildlife loss.

What is being done to address water scarcity in Tunisia?

The Tunisian government has implemented a range of policies and initiatives to address water scarcity, such as promoting water conservation measures, investing in water infrastructure, and enhancing monitoring and management of water resources. The government is also working with international partners to develop innovative solutions to improve water management, such as desalination and water reuse. However, there is still much work to be done to ensure adequate water supply for all Tunisians, particularly in rural and marginalized communities.
