Why the Azores Must Learn to Protect What Once Seemed Infinite
There are few landscapes on earth that appear as blessed by water as the Azores. Rain arrives with remarkable generosity, clouds drift endlessly across volcanic peaks, waterfalls descend into emerald valleys, and springs have nourished communities for centuries. For generations, water has seemed less a resource than an unquestioned companion of island life—so abundant that its permanence appeared beyond discussion. Yet one of the quiet lessons of the twenty-first century is that abundance can be deceptive. Nature rarely promises permanence. Even in places where water has always defined the landscape, its future depends increasingly upon human wisdom.
That is the central message emerging from an important interview with Sandra Aguiar e Câmara, President of the Board of the Regulatory Authority for Water and Waste Services of the Azores (ERSARA). Her reflections offer more than a technical assessment of water management. They challenge one of the oldest assumptions in the Azorean imagination: that water will always be there simply because it always has been.
The Azores continue to enjoy rainfall levels that many parts of the world can only envy. From a purely climatic perspective, the archipelago possesses considerable hydrological wealth. Yet appearances, as Sandra Aguiar e Câmara reminds us, can be misleading. When examined island by island, municipality by municipality, even watershed by watershed, vulnerabilities begin to emerge. Local shortages, aging infrastructure, saltwater intrusion into coastal aquifers, significant losses in distribution networks, insufficient monitoring, and increasing demand from expanding urban centers and tourism all reveal that abundance is no guarantee of security.
Perhaps the most striking phrase in the interview is also its most profound: “apparent abundance may be illusory.” It is a sentence that extends beyond engineering into philosophy. Throughout history, civilizations have often mistaken plentiful resources for inexhaustible ones. Forests disappeared because they seemed endless. Fisheries collapsed because the sea appeared infinite. Today, water joins that list of natural gifts requiring not complacency but stewardship.
The challenge facing the Azores is therefore not one of immediate scarcity but of responsible foresight. Water management is increasingly about preventing crises rather than responding to them. Climate variability, prolonged dry periods, and changing patterns of consumption demand a different mentality—one that replaces confidence born of habit with resilience built through planning.

ERSARA identifies several structural weaknesses that require continued attention. High levels of water loss in distribution systems remain among the most persistent problems. Many supply networks still lack complete infrastructure inventories, licensed water sources remain insufficient in some areas, protective zones around groundwater catchments are not universally implemented, and operational efficiency varies significantly among municipalities. These are not failures of nature; they are challenges of governance, investment, and long-term management.
The interview also reveals another reality often overlooked in discussions about the Azores: the archipelago is not hydrologically uniform. Larger islands generally benefit from economies of scale, more diversified water sources, and stronger technical capacity. Smaller islands frequently operate more vulnerable systems, with greater dependence on individual springs or aquifers and fewer alternatives should problems arise. Geography itself creates unequal conditions, requiring policies that acknowledge those differences rather than assuming identical solutions across nine distinct islands.
Among the concerns raised, few deserve greater attention than the growing possibility of saltwater intrusion into freshwater aquifers. While not yet a widespread structural problem across the archipelago, ERSARA warns that islands such as Pico and Graciosa may become increasingly vulnerable if preventive measures are not strengthened. Once coastal aquifers become contaminated by seawater, restoration becomes extraordinarily difficult. Prevention, therefore, is not merely advisable—it is essential. Continuous monitoring, careful regulation of groundwater extraction, reduction of distribution losses, protection of aquifer recharge zones, and diversification of water sources form the foundation of that preventive strategy.

Yet the interview avoids alarmism. It recognizes the considerable progress already achieved throughout the Region. Significant investments in infrastructure, improved monitoring systems, and the implementation of the Azores Drought and Water Scarcity Management Plan (2025) have strengthened the Region’s preparedness. Water supplied for human consumption continues to meet exceptionally high quality standards, with 99.26 percent classified as safe drinking water in 2024—a remarkable achievement reflecting the dedication of municipal utilities, technical professionals, and regulatory oversight.
Indeed, the paradox facing the Azores is that the very success of its water systems may contribute to public complacency. Because clean water flows reliably from household taps, many citizens naturally perceive it as guaranteed. Few pause to consider the reservoirs, treatment facilities, pumping stations, laboratories, monitoring systems, engineers, technicians, and public investments that quietly sustain that everyday miracle. Modern civilization has an unfortunate tendency to notice infrastructure only when it fails.
This is why ERSARA places growing emphasis on water literacy. Technical solutions alone cannot ensure long-term sustainability if public attitudes remain unchanged. Citizens who understand the true value of water are more likely to conserve it, support necessary investments, accept realistic pricing structures, and recognize that every liter delivered safely represents both environmental stewardship and public responsibility. Water conservation is ultimately not a matter of restriction but of respect.

There is also a distinctly Azorean dimension to this conversation. These islands were born from fire but have always lived through water. Volcanic landscapes collect rainfall, nourish aquifers, feed streams, and sustain agriculture, communities, and ecosystems found nowhere else in the world. Water is not simply another public utility. It is one of the archipelago’s defining inheritances, shaping everything from its forests and pastures to its economy, culture, and identity.
Perhaps this is the deeper lesson hidden within ERSARA’s interview. The future of the Azores will not depend solely upon possessing abundant natural resources. It will depend upon learning to govern them wisely. The islands have long been blessed with extraordinary gifts of nature. The responsibility of this generation is to ensure those gifts remain equally abundant for the generations that follow.
Because water, like autonomy, is never truly secured by inheritance alone.
It is preserved through vigilance, responsibility, and the quiet wisdom to protect today what tomorrow will depend upon.
