In Greece, public debate often focuses on energy, investment, economic growth, and climate policy. Far less attention is paid to water. Yet water is the resource that underpins all of the above. Without water, there is no agriculture, no tourism, and no urban development. Today, this critical resource is under pressure that can no longer be ignored.

Water scarcity is not a rare phenomenon occurring every few years. It has become a new normal, shaped by climate change, chronic overexploitation, and structural weaknesses in the way water resources are managed. As long as water scarcity continues to be treated as an “emergency situation” rather than a permanent and systemic risk, policy responses will remain reactive and insufficient.

This is not a uniquely Greek challenge. At the European level, water scarcity and pressure on water resources are increasingly recognised as strategic risks. This is clearly reflected in the Water Framework Directive (2000/60/EC)
https://environment.ec.europa.eu/topics/water/water-framework-directive_en
as well as in the broader strategic objectives of the European Green Deal

Greece, however, faces a particular structural challenge that intensifies the problem: water availability does not align with demand. Precipitation is concentrated mainly during the winter months, while demand peaks in the summer, when tourism activity surges and agriculture requires significant water inputs to remain viable. This mismatch is not theoretical. It is the primary driver behind the water deficits that are occurring with increasing frequency across the country.

For those who assume that water scarcity concerns only a limited number of arid regions, the data tell a different story. Approximately 74% of total water consumption in Greece is allocated to agriculture. In many areas, groundwater abstraction has reached critical levels. Groundwater reserves, however, are not infinite. They function as the country’s natural “savings account”. When withdrawals consistently exceed natural recharge rates, the consequences are inevitable. When they materialise, they are costly and often difficult—if not impossible—to reverse.

The Aegean islands represent the clearest warning signal. During the summer season, population levels in many islands increase by a factor of ten or even fifteen. Water availability does not. The prevailing response has been the transfer of water from mainland Greece—a solution that may provide short-term relief but is neither cost-effective, nor sustainable, nor strategic. The result is long-term dependency and a steadily growing environmental footprint.

The issue, therefore, is not a lack of knowledge. The necessary solutions are well understood—and have been for years, including at the European level. The Water Framework Directive explicitly calls for integrated river basin management, protection of both quantitative and qualitative water status, and the prevention of over-abstraction. The challenge lies not in the regulatory framework itself, but in its effective implementation.

International experience demonstrates that the era of supply-driven water management has come to an end. Water challenges cannot be resolved indefinitely through new abstractions or the physical transfer of resources from one area to another. What is required is demand-side management: reducing losses, improving network efficiency, deploying smart irrigation technologies, promoting water reuse, and protecting ecosystems that function as natural storage and regulation systems.

At this point, the political dimension becomes unavoidable. This transition is not merely a technical exercise; it is fundamentally a matter of policy choices. It requires changes in incentives, the willingness to challenge entrenched practices, and the establishment of a clear, stable governance framework with continuity over time. Water governance must be addressed as a matter of national strategic importance.

Simultaneously, the European regulatory environment is becoming more demanding. Water has moved to the core of the ESG agenda. Under the Corporate Sustainability Reporting Directive (CSRD), large companies and financial institutions are required to disclose water consumption, water-related risks, and the measures taken to mitigate them

This has a very practical implication: inadequate data, weak infrastructure, and ineffective water management are no longer solely environmental concerns. They now directly affect economic competitiveness and access to capital.

In parallel, the EU Taxonomy defines which investments can be classified as environmentally sustainable. Sustainable use and protection of water resources constitute one of its six environmental objectives

Projects that reduce losses in water networks, promote reuse, enhance resilience to water scarcity, and protect water bodies now enjoy a clear advantage in terms of access to financing. The message is unequivocal: failure to invest effectively in water management increasingly translates into strategic and financial disadvantage.

Greece therefore stands at a crossroads. It can continue to treat water scarcity as an inconvenient yet manageable issue. Or it can recognise it for what it truly is: a systemic risk requiring a coherent and forward-looking strategic response.

Water does not wait. And the longer adaptation is delayed, the higher the cost will be. If the country is serious about sustainable development, investment attractiveness, and long-term resilience, it must first address the most fundamental question of all: how to ensure that water—the most essential of all resources—does not become the weakest link in Greece’s future.

And this question can no longer be postponed.

The answer, however, does not lie solely in constructing new infrastructure. The European Union does not issue “mandates” for more projects. It sets qualitative and governance objectives: good quantitative and chemical status of water bodies, prevention of deterioration, integrated river basin management, and the application of the cost recovery principle. The framework is clear: sustainability, transparency and financial discipline.

Within this context, the national YDOR 2.0 programme represents a large-scale Greek initiative launched in recent years to address long-standing irrigation challenges through the construction and upgrading of dams, irrigation networks, reservoirs, water transfer and distribution systems, as well as smart irrigation technologies. The programme is implemented through Public-Private Partnerships (PPPs), with significant support from the Recovery and Resilience Facility (RRF), and aligns substantively with the objectives of the Water Framework Directive and broader European policies on climate resilience and efficient resource use.

Within YDOR 2.0, FCNC provides financial advisory services for the Tavropos irrigation PPP project, contributing to the development of a sustainable financing and contractual structure for a project of strategic importance.

At the same time, in a regulatory environment undergoing significant transformation, FCNC supports Municipal Water Supply and Sewerage Companies. Under the evolving institutional framework and the oversight of the Regulatory Authority for Waste, Energy and Water (RAWEW), water service providers are required to strengthen their managerial capacity, enhance financial sustainability and ensure compliance with the European cost recovery principle.

The preparation of comprehensive business plans and the adoption of modern pricing policies that reflect the actual cost of water services—aligned with RAWEW guidance and EU water governance requirements—are no longer merely best practices, but essential instruments for ensuring sustainable operations, access to European funding and the effective implementation of EU principles on water cost and resource management.

Ultimately, sustainable water management is not solely a technical matter. It is a question of economic organisation, institutional consistency and investment maturity. From large-scale irrigation PPPs to the operational restructuring of municipal companies, the challenge is the same: to connect environmental responsibility with financial sustainability.

That is where water will either become a pillar of resilience — or the country’s weakest link.
