In July 1980, Frank Herbert made a declaration that reads differently today than it did then. “The scarce water of Dune is an exact analog of oil scarcity,” he wrote in Omni Magazine. “CHOAM is OPEC.”[s] At the time, readers understood this as commentary on petroleum politics. More than four decades later, as water scarcity geopolitics reshapes international relations from the Indus to the Nile, Herbert’s allegory has acquired a second, more literal meaning.
The author who dedicated his novel to “dry-land ecologists, wherever they may be, in whatever time they work” was not writing about a distant future.[s] He was writing about a present that had not yet arrived.
Oregon Dunes: Where Water Scarcity Geopolitics Began
The genesis of Arrakis lies in Florence, Oregon. In the late 1950s, Herbert flew over the Oregon coast in a rented Cessna to research a magazine article on a US Department of Agriculture programme to stabilise migrating sand dunes.[s] The Soil Conservation Service had been planting beach grass beds around the town, hoping to halt the advance of sand that threatened to swallow entire communities.
Herbert never finished that article. But what he observed in Oregon transformed into something larger: research into deserts, desert cultures, and the political economy of scarcity. As scholar Veronika Kratz notes, “What the Fremen are doing in terms of their own terraforming project is really coming directly from the dunes. In a sense, it is the Oregon dunes transposed to an entire planet.”[s]
The timing mattered. Dune emerged from the same intellectual ferment that produced Rachel Carson’s Silent Spring in 1962. According to research published in The Anthropocene Review, Dune became “the paradigmatic fantasy of the awakening of the environmental awareness in the United States.”[s] Herbert intuited something the environmental movement was still articulating: the core insight of water scarcity geopolitics is that resources are power, and whoever controls the vital substance controls the system.
The Arithmetic of Water Bankruptcy
In January 2026, UN News reported that United Nations University researchers had warned the world had entered an era of “water bankruptcy.” Kaveh Madani, Director of the UN University Institute for Water, Environment and Health, said: “For much of the world, ‘normal’ is gone.”[s]
The term is not metaphorical. Water bankruptcy describes a chronic condition where a place uses more water than nature can reliably replace.[s] It implies both insolvency and irreversibility: the aquifers are overdrawn, the lakes are shrinking, and the capacity to recover is diminishing.
The statistics constitute their own kind of prophecy fulfilled. More than half the world’s large lakes have declined since the early 1990s. Around 35 percent of natural wetlands have been lost since 1970.[s] Close to 75 percent of the world’s population lives in countries classified as “water-insecure” or “critically water-insecure.”[s] About 4 billion people face severe water scarcity for at least one month each year.[s]
Herbert anticipated the structural logic. “Beyond a critical point within a finite space, freedom diminishes as numbers increase,” he wrote. “This is as true of humans in the finite space of a planetary ecosystem as it is of gas molecules in a sealed flask.”[s]
Water Scarcity Geopolitics in Action: The Indus Crisis
In April 2025, India suspended the Indus Waters Treaty following a terrorist attack in Kashmir.[s] The treaty, signed in 1960 after World Bank-backed negotiations, had governed water sharing between the two nuclear-armed neighbours for 65 years.[s] Its suspension was, in Herbertian terms, a declaration that water would now serve as a strategic weapon.
A February 2026 PNAS article described the stakes: “Such actions were viewed by Pakistan as an existential threat, since its irrigated agriculture and food security depend heavily on water from India.”[s] Pakistan’s National Security Committee warned that “any diversion of Pakistan’s water is to be treated as an act of war.”[s]
Indian Home Minister Amit Shah declared in June 2025: “It will never be restored.”[s] Prime Minister Modi had foreshadowed this approach nine years earlier, after the 2016 Uri attack: “Blood and water cannot flow at the same time.”[s]
The Indus crisis exemplifies how water scarcity geopolitics operates when pushed to extremes. But it is not an outlier. In 2024, the Pacific Institute recorded 420 water-related conflicts worldwide, a new record, according to its November 2025 update.[s]
Hydro-Hegemony: Control the River, Control the Region
Herbert’s CHOAM cartel finds multiple real-world analogs. GIS Reports argues that Turkey’s Southeastern Anatolia Project reduced flows by up to 40 percent on the Tigris and 90 percent on the Euphrates, engineering “a strategic denial that halved Iraq’s winter crops, dried the Mesopotamian Marshes.”[s] Ethiopia’s Grand Ethiopian Renaissance Dam challenges Egypt’s historical control over the Nile, upon which Egypt depends for over 90 percent of its fresh water.[s]
The economics of scarcity in these basins follow a logic Herbert would recognise. Unlike oil or gas, water has no substitute. “Unlike energy, where technological advancements can offer replacements for coal, oil and gasoline, there is no alternative to water,” GIS Reports observes.[s] This irreplaceability makes water scarcity geopolitics more consequential than petroleum politics ever was.
Understanding the mechanics of these energy security flashpoints requires recognising how resource control translates into political leverage. The upstream nation holds the cards. The downstream nation depends on their mercy. The calculus applies whether the resource is spice, oil, or water.
The Counter-Argument: Cooperation Over Conflict
Not everyone accepts the water-wars narrative. Researcher Jeremy Allouche at the Institute of Development Studies argues that “cooperation over water is far more common than conflict. Since 1945, approximately 300 treaties dealing with water management and allocations in international basins have been negotiated.”[s]
This critique has merit. Water has rarely been the primary cause of interstate war. The historical record shows more treaties than battles, more negotiations than invasions. Scarcity, Allouche argues, is shaped by “politics, infrastructure, technology, and power,” not hydrology alone.[s]
Yet Herbert would recognise this framing too. Dune is not a novel about inevitable conflict; it is a novel about how power structures form around scarce resources, how those structures produce both collaboration (the Fremen water-sharing rituals) and domination (the Harkonnen spice monopoly). The question is not whether water causes war, but how water scarcity geopolitics reshapes the conditions under which power is exercised.
Science Fiction as Cultural Critique
Herbert called Dune “an effort at prediction.”[s] Whether this was retrospective positioning or genuine intent, the novel now functions as a template for understanding resource politics in the 21st century. Science fiction as cultural critique works not because it forecasts specific events, but because it maps the logic of systems.
The UN’s 2026 report warned: “If we continue to manage these failures as temporary ‘crises’ with short-term fixes, we will only deepen the ecological damage and fuel social conflict.”[s] Herbert would have nodded. Arrakis was never a crisis to be managed; it was a system to be understood.
In his 1980 essay, Herbert explained that his oil analogy “was only the beginning.”[s] More than six decades after Dune’s publication, water scarcity geopolitics has vindicated the author’s planetary vision. The question that remains is whether readers of the 21st century will recognise themselves in the Fremen’s discipline and foresight, or in the Harkonnens’ extraction and collapse.
