A Year of Extremes: Climate Shocks and Water Stress

In 2024, the Mediterranean weathered a brutal year, one that laid bare the region’s growing vulnerability to climate change. From prolonged droughts to sudden, devastating floods, the year was marked by extremes that strained already fragile water systems and exposed the deep socioeconomic fault lines across multiple countries.

Morocco endured its sixth straight year of agricultural hardship, with rainfall more than 50% below average. The effects rippled through the food system, decimating cereal production by over 40% and shrinking livestock numbers by nearly 40% over a decade. In Spain, regions like Andalusia and Catalonia faced crippling water shortages. Emergency irrigation bans were enforced as reservoirs dried out, and the agricultural sector suffered losses upwards of €8 billion. Tunisia, meanwhile, struggled with collapsing dam systems and exhausted aquifers, leading to both urban water shortages and the collapse of certain high-value crop industries.

Yet while drought parched the land, rain overwhelmed it elsewhere. Eastern Spain experienced flash floods so severe they claimed over 230 lives and caused more than €10 billion in damages. In southern France, rainfall topped 650 mm in a matter of days, flooding infrastructure across 33 departments. Bosnia and Herzegovina saw its worst flooding since 2014, while in northern Lebanon, thousands of homes were left under water and vast stretches of farmland were ruined.

This dichotomy — flood and drought occurring simultaneously — is becoming the new normal. And the message it sent out was loud and clear: reactive crisis response is no longer enough. What the region needs now is forward-looking, systemic resilience.

Water and Nature: Biodiversity on the Brink

The retreat of rivers and shrinking freshwater flows are pushing marine ecosystems to their limits. In some basins, river inflows dropped by more than 40%, upsetting the delicate balance of salinity, temperature and nutrients. The result? A 10% decline in marine biological productivity that has devastated fish stocks and the communities that depend on them.

Fisheries in the Mediterranean are not just an ecological asset — they’re a lifeline for millions. Annual losses in the fishery sector now exceed €4.7 billion, especially harming small-scale fishers in North Africa and southern Europe. Warmer, saltier waters have also created a haven for invasive species, which are further undermining already stressed ecosystems.

In response, some countries are turning to nature for solutions. Greece, with backing from the European Investment Bank, initiated floodplain restoration and forest rehabilitation projects in flood-prone areas like Thessaly. These investments, projected to be more cost-effective over 25 years, offer multiple returns: better flood control, enhanced biodiversity, carbon storage and even improved agricultural productivity.

Turning to Technology: Innovation for Resilience

Faced with these growing threats, many Mediterranean governments are putting their faith in technology — and rightly so. Countries are diversifying their water sources, improving demand management and expanding adaptive capacity through digital tools and innovation.

Spain, for example, is scaling up solar-powered desalination facilities along the southeastern coast, backed by more than €3 billion in climate resilience funding. Cyprus rolled out mobile desalination units to deal with seasonal demand, while Morocco’s large-scale solar desalination projects in Agadir and Casablanca are moving swiftly ahead. Tunisia made progress on long-stalled facilities like the Sfax plant, which will deliver 100,000 m³/day of fresh water via reverse osmosis.

Countries are also beginning to take wastewater seriously. Egypt, with help from digital water accounting tools and blended finance, has ramped up the reuse of treated wastewater in the Nile Delta. Tunisia has introduced decentralized schemes to reuse treated water in peri-urban farms.

Digital tools are no longer an experiment — they’re becoming the backbone of governance. Real-time monitoring, remote sensing, and AI-powered forecasting are now being used to map underground water, monitor usage and predict future droughts. Smart irrigation, automated metering and integrated data platforms are guiding decisions at both policy and farm levels.

Morocco’s solar-powered irrigation plan is one of the standout initiatives. Set to cover 51,000 hectares and reach 30,000 farmers by 2027, the programme is backed by the International Finance Corporation and Moroccan partners. It shows how clean energy, precision agriculture and access to finance can come together to build resilience.

The road ahead is promising — but only if innovation remains inclusive, affordable and rooted in ecological principles.

Driving Water Efficiency in Mediterranean Agriculture

With agriculture still the top user of freshwater in the region, boosting water efficiency in farming has become non-negotiable. In the EU, the latest Common Agricultural Policy (CAP) encourages climate-smart farming, offering support to farmers who embrace resource-efficient techniques. The European Commission is also driving broader efficiency measures aimed at slashing water use by 10% across the bloc by 2030. Infrastructure upgrades, advanced irrigation systems and treated water reuse are all on the table.

Precision irrigation, for example, is gaining traction. With the help of soil sensors and satellite imagery, farmers can now water their crops precisely when and where it is needed. This not only curbs waste but also sustains yields in the face of growing uncertainty. Coupled with drought-resistant crop varieties, these tools are helping farms remain productive even in extreme conditions.

Northern Mediterranean countries have begun aligning policies, pooling funding and setting technical standards. This regional coordination is beginning to pay off, demonstrating how collective effort can accelerate the shift to smarter water use.

On the southern shores, 2024 was a year of progress as well. Morocco, Tunisia and Egypt invested heavily in modern irrigation, upgraded storage systems and smart advisory tools for farmers. Morocco’s Green Generation Plan has supported new pilot programmes that bring precision irrigation and remote advisory services to smallholder farms.

Tunisia is reshaping its agricultural water policies by integrating technology with training programmes tailored to vulnerable rural communities. In Egypt, where water scarcity is especially severe, major upgrades are underway in irrigation canals and wastewater use is being scaled for agriculture, easing pressure on the Nile.

Financing the Future: Water Investment and Partnerships

If 2024 marked a turning point, it was also thanks to money finally moving in the right direction. Mediterranean countries secured record levels of funding for water-related projects, reflecting a shared understanding that water insecurity is both a climate and economic threat.

Still, not all regions are benefitting equally. Northern Mediterranean nations continue to attract more investment and support than their southern neighbours. Egypt’s Team Europe Water Sector Initiative stands out, drawing €600 million in grants and unlocking a total of €3.5 billion in water infrastructure projects. Spain committed €3 billion to its Valencia Climate Resilience programme. Morocco secured €500 million from the European Investment Bank, and Tunisia received a €250 million loan from Japan to finally push forward the Sfax desalination plant.

Multilateral efforts also gained momentum. The new Blue Mediterranean Partnership, launched in 2024, is aiming to mobilize over €1 billion for sustainable water and ocean initiatives. Meanwhile, the Interreg NEXT MED Programme opened up more than €80 million for climate-smart, cross-border water solutions.

But challenges remain. Southern countries struggle with weak institutions, patchy regulations, and project pipelines too small or too risky for private investment. To address this, stakeholders must invest in local capacity, develop de-risking tools, and support the design of high-quality, fundable projects.

Public-private partnerships are slowly gaining ground, especially in desalination and wastewater reuse. Morocco’s Chtouka and Agadir desalination projects are examples of PPPs that work — bringing public oversight and private efficiency together. Egypt is following suit, especially in wastewater, with growing support from development banks and private investors. With the right enabling environment, these partnerships could become a regional model.

Governing the Nexus: From Silos to Systems

In 2024, the Water-Energy-Food-Ecosystem (WEFE) Nexus approach moved from concept to action across much of the Mediterranean. Countries gathered in Rabat and Malta to design tools for digital governance, financing, and cross-sector planning. The Union for the Mediterranean is backing a draft Nexus Strategy to unify water, food and energy policy across borders.

This shift is critical. In the north, countries are using the Nexus to revamp food and energy systems. In the south, it’s a strategy to tackle water shortages, hunger and climate risk simultaneously. Cross-border projects, such as the Gendering the WEFE Nexus pilot, are making adaptation more inclusive and community-led. Climate cooperation platforms like PRIMA and WestMED are also pushing the agenda forward.

The MedECC 2024 report drove home the urgency. It warned that fragmented governance and siloed policymaking are slowing progress. According to MedECC, Nexus thinking is not a luxury but a necessity. It helps manage trade-offs and unlock synergies, especially in a region where growing populations, stressed environments and climate shocks collide.

To put the Nexus into practice, countries need stronger institutions, local expertise and better ways to share knowledge. Aligning investment, regulation and innovation through grounded, cross-sector strategies will be essential.

What Next? A Mediterranean Blueprint for Water Resilience

What 2024 made abundantly clear is that water security is no longer an isolated issue — it is the backbone of everything. To navigate a future of increasing climate volatility, the Mediterranean needs a bold, integrated vision.

First, that means investing in resilient, climate-smart water infrastructure: from ecosystem restoration to desalination plants powered by renewables. These systems must be low-carbon, adaptable and designed to withstand climate extremes.

Second, it requires embedding digital innovation at every level. From real-time water flow data to predictive analytics and satellite-based monitoring, digital tools are the key to smarter governance and faster responses.

Third, the funding gap must be closed. This involves expanding PPPs, making better use of blended finance and ensuring that climate funds reach southern shores, where needs are most urgent.

Water must also be integrated into broader development agendas. It needs to be central to agriculture, energy, climate adaptation and economic planning. This integration will help stretch investments and build systems that are both efficient and resilient.

Finally, inclusivity must become a core principle. The voices of women, youth and local communities are vital to designing and delivering the kinds of solutions that last.

In sum, the Mediterranean stands at a crossroads. The shocks of 2024 revealed deep vulnerabilities but also illuminated a path forward. With smarter policies, stronger cooperation and focused investment, the region can turn water from a source of risk into a foundation for shared prosperity.
