Tunisia Faces 'Structural Water Crisis' as AfDB Unveils Major Drought Resilience Strategy

The study forms part of Tunisia’s broader effort to modernise its climate adaptation strategy and align water security planning with its National Water Strategy to 2050.

Tunisia is confronting a long-term transformation of its climate and water systems rather than a temporary drought emergency, according to a major new report unveiled by the African Development Bank and the Tunisian government, warning that rising temperatures, declining rainfall and growing water demand threaten the country's economic and social stability.

The report, titled "Drought Planning, Preparedness and Resilience Strategies: The Case of Tunisia," outlines a comprehensive national framework designed to help Tunisia adapt to intensifying drought conditions through institutional reform, climate planning and long-term investment in water resilience.

The study forms part of Tunisia's broader effort to modernise its climate adaptation strategy and align water security planning with its National Water Strategy to 2050.

Tunisia Facing Intensifying Climate and Water Pressures

The report paints a stark picture of Tunisia's mounting water challenges, describing the country as increasingly vulnerable to chronic drought conditions driven by both climate change and growing human demand.

According to the analysis:

• Between 1950 and 2018, approximately:

  • 59 per cent of years in Tunisia were classified as dry

• Climate projections indicate:

  • Rainfall could decline by up to 25 per cent in central and southern Tunisia by 2100

  • Average temperatures could rise between:

    • 2.5°C and 5°Cdepending on global emissions scenarios

The findings underscore growing fears across North Africa that climate change is accelerating desertification, intensifying water scarcity and threatening food systems, infrastructure and economic development.

Agriculture Driving Massive Water Consumption

The report identifies agricultural water use as one of the central pressures on Tunisia's already strained water resources.

Currently:

• Agriculture accounts for approximately:

  • 80 per cent of Tunisia's total water consumption

At the same time, domestic water demand has risen sharply.

The volume of water withdrawn for drinking water supply increased from:

• 296.2 million cubic metres in 2002to

• 447.2 million cubic metres in 2018

Officials say rapid urbanisation, population growth, rising temperatures and changing consumption patterns are all contributing to increasing stress on the country's water systems.

African Development Bank Calls for Shift From Crisis Response to Resilience Planning

The African Development Bank says Tunisia must now move beyond reactive emergency responses and adopt a long-term resilience-based strategy.

Yero Baldeh, Director of the Bank's Transition States Coordination Office, said the country is experiencing a structural shift in climate conditions rather than isolated drought cycles.

"Tunisia is not facing a temporary water crisis; it is facing a structural transformation of its climate regime," Baldeh said.

"This report does not propose emergency measures; it proposes an architecture for resilience."

He added that the African Development Bank stands ready to support Tunisia in implementing reforms and investments linked to water security and climate adaptation.

Six Priority Areas Identified

The report proposes six key strategic priorities designed to strengthen Tunisia's resilience to worsening drought conditions.

1. Stronger Institutional Coordination

The report warns that fragmented governance structures currently weaken water management and drought response systems.

Officials recommend improved coordination between ministries, regional authorities and water agencies.

2. National Early Warning System

The study calls for development of a comprehensive drought early warning system capable of monitoring climate risks, forecasting shortages and supporting faster policy responses.

3. Legal and Regulatory Reform

Modernisation of Tunisia's water governance laws and regulatory frameworks is identified as essential for managing increasing scarcity and ensuring sustainable resource allocation.

4. Innovative Financing Mechanisms

The report urges Tunisia to expand financing sources for water infrastructure, climate adaptation and resilience investments.

This may include:

• Public-private partnerships

• Climate finance

• International development funding

• Blended finance mechanisms

5. Technical Capacity Building

Strengthening technical expertise at national, regional and local levels is viewed as critical to improving implementation and long-term resilience planning.

6. Promoting Responsible Water Use

The report also emphasizes the importance of public awareness campaigns and behavioural change initiatives aimed at reducing water waste and encouraging sustainable consumption.

Water Security Emerging as National Stability Issue

Climate experts increasingly warn that water scarcity in North Africa poses not only environmental risks, but also economic, agricultural and geopolitical challenges.

Tunisia's economy remains heavily dependent on sectors vulnerable to climate stress, including:

• Agriculture

• Food production

• Tourism

• Rural livelihoods

Declining water availability threatens:

• Crop yields

• Food security

• Rural employment

• Energy systems

• Public health

The report argues that coordinated adaptation policies are essential to reducing long-term economic disruption and social vulnerability.

Practical Implementation Now Key Challenge

African Development Bank officials stressed that Tunisia already possesses strong technical expertise and strategic planning frameworks, but implementation and coordination remain major challenges.

Malinne Blomberg, Deputy Director General for North Africa and the Bank's Country Manager for Tunisia, said the report is intended as a practical operational tool rather than simply another policy document.

"Tunisia has real technical expertise, an ambitious strategic framework, and the political will confirmed by this workshop," Blomberg said.

"The challenge now is to strengthen coordination among these resources."

"This report precisely identifies the breaking points and proposes solutions tailored to the country's institutional realities. It is not just another document; it is a working tool."

Climate Adaptation Becoming Central to African Development Planning

The publication reflects a broader shift across Africa toward integrating climate adaptation directly into national development strategies.

Many African countries are increasingly prioritising:

• Water security

• Climate resilience

• Sustainable agriculture

• Infrastructure adaptation

• Disaster preparedness

Development banks and international institutions warn that climate-related water crises could become one of the defining economic and humanitarian challenges of the coming decades, particularly across arid and semi-arid regions.

The African Development Bank says its partnership with Tunisia will continue focusing on reforms and investments aimed at:

• Strengthening water security

• Expanding climate resilience

• Protecting vulnerable populations

• Supporting sustainable economic growth

As drought conditions intensify globally, Tunisia's experience may increasingly serve as a case study for how climate-vulnerable nations attempt to adapt to a rapidly changing environmental reality.
