Water: From Source of Life to Geopolitical and Economic Frontier

In the 20th century, the world was shaken by the scramble for oil. Major nations built war fleets, toppled governments, and formed global alliances to secure fossil energy. Oil became the lifeblood of modern geopolitics; whoever controlled oil wielded immense influence over the world economy.

However, entering the 21st century, a new awareness has slowly emerged: there is something that may be far more important than oil. Something more fundamental than gold, stocks, or high technology. Something that has silently underpinned all of human civilisation since its dawn: water.

Many people once considered water merely an environmental issue—a matter of rivers, dams, irrigation, or sanitation. But a number of thinkers have begun to see that water is actually moving to the centre of modern economic and geopolitical struggles. One of the most famous figures in this discourse is Ismail Serageldin, former Vice President of the World Bank and later head of the Bibliotheca Alexandrina in Egypt. He once made a highly provocative statement: ‘The wars of the next century will be about water.’

When that statement emerged in the early 1990s, many considered it overly dramatic. The world at that time was still preoccupied with globalisation, trade liberalisation, and post-Cold War euphoria. But three decades later, Serageldin’s warning feels increasingly real. Just look at the world map today. Egypt and Ethiopia are in a standoff over a dam on the Nile River. India and Pakistan have long-standing tensions regarding the Indus River. Turkey controls the headwaters of the Tigris and Euphrates. Gaza is experiencing a protracted water crisis. Africa faces conflicts due to drought. Even developed countries are beginning to experience serious pressure on their water reserves. The world is waking up to the fact that water is not just a biological necessity; it is a geopolitical force.

This view was later reinforced by Peter H. Gleick through his highly influential article, ‘Water and Conflict: Fresh Water Resources and International Security,’ published in International Security. If Serageldin issued a grand warning, Gleick explained the mechanisms systematically. He showed that water can become a trigger for conflict, a tool of war, a target of war, and even a victim of war. This concept is highly relevant to modern warfare. Today, we see how water infrastructure can be destroyed in conflicts. Dams can be used as tools of political pressure. Water supplies can be cut off to weaken civilian populations. Transboundary rivers become sources of geopolitical tension. Water is slowly transforming from a source of life into an instrument of power.

Leonardo da Vinci called water the driving force of all nature, while W.H. Auden reminded us that thousands may live without love, but not one without water. Lao Tzu observed that nothing is softer than water, yet nothing can resist it. In a more spiritual tone, Jalaludin Rumi saw humans not as a drop in the ocean, but as the entire ocean in a drop. However, in the modern era, these reflective tones have shifted to warnings. Ismail Serageldin cautioned that future wars would be fought over water, Peter H. Gleick explained how water becomes a tool of conflict and power, while Willem Buiter viewed water as the most strategic physical asset of the future. Amidst all this, Vandana Shiva reminds the world that water is not merely a commodity, but life itself.

This is the great irony of modern civilisation. Something that should be a shared blessing is now being contested like a strategic weapon. But the story of water does not end with geopolitics and war. The global financial world has also begun to see water as a new economic frontier. This is where Willem Buiter enters the picture. In 2011, the top economist from Citigroup made a startling analysis: the water market will one day surpass oil, agriculture, and even precious metals. The statement sounded extreme, but its logic is simple. Oil has alternatives: solar, wind, nuclear energy. Metals can be recycled. But water? There is no biological substitute for water. Humans can live without smartphones, without cars, even without modern electricity. But humans cannot live without water. For this reason, Buiter sees water as the ultimate asset of the future.

And perhaps this is the most worrying point of modern civilisation. When water begins to be viewed primarily as an economic asset, market logic slowly seeps into the very foundation of human life. Water is being traded. Water rights are being bought and sold. Privatisation of water is expanding. Multinational corporations are entering the water resources sector. Even water futures markets are beginning to appear in the financial world. Water is gradually moving from being a right to life to becoming an investment instrument. This is where the moral problem arises. Because when water is treated entirely as a commodity, access to life itself becomes subject to purchasing power. The wealthy can access quality water. The poor struggle to get clean water. The water crisis slowly transforms into a crisis of justice. In many cases, international financial institutions have even encouraged the privatisation of the water sector as part of economic reform packages for developing countries. The rationale sounds sensible: efficiency, investment, infrastructure modernisation. But the reality on the ground is often far more complicated. The Cochabamba case in Bolivia in 2000 became a global symbol of resistance against water privatisation. Tariffs rose drastically. The people were enraged. Massive demonstrations erupted. The world began to ask: is it right to treat water like an ordinary commodity?
