The underlying premise is simple: without water we die. As a Turkish businessman quoted in Marq de Villiers’ impressive book, Water: The Fate of Our Most Precious Resource, says, “Millions have lived without love. No one has lived without water.”

In Water, de Villiers, who grew up in South Africa and lives in Nova Scotia, tours the world to examine the state of its most vital resource. What he finds is not encouraging. From Africa to Asia and Australia, from Europe to the Middle East and the Americas, too many people depend on too little — and increasingly limited — water. Despite Herculean engineering schemes constructed to water deserts and to store and deliver water where it would otherwise not be available, demand for water will almost surely continue to outstrip supply unless we dramatically alter our behavior.

In addition to the problems of supply and demand, de Villiers describes the ecological damage incurred by the use and abuse of water sources. Through pollution, diversion, and degradation, industrialization of the world has taken a heavy toll on water quality. On every continent, rivers have been straightened to ease navigation, bermed and banked for flood control, dammed and diverted for irrigation, and used as receptacles for noxious and toxic waste. To facilitate development, wetlands have been drained, natural flows and stream channels altered. The result is a world where most major rivers and lakes no longer retain their full ecological function. This reality, as de Villiers explains with many illuminating examples, severely hampers how water sources replenish and renew themselves.

Now, with surface water exploited nearly to the maximum extent possible, countries around the world have begun tapping groundwater — the primary water source in areas with little rainfall and few lakes or rivers. As underground aquifers begin to be depleted, there is concern about further upsetting the ecological balance. Diverting water from one river basin to another — which, until now, has been largely a matter of economics and geopolitics, as in Southern California — quickly becomes a matter of survival in a developing nation like Namibia, as over-allotment of water in one area leads to desertification in another.

Rooting his narrative in memories of his grandfather’s farm in arid South Africa, de Villiers is fierce about recognizing the value of clean, uncompromised water. He has done his homework thoroughly and brings both ecological and historical knowledge to bear in his frank criticism of how the world’s water resources have been managed. At his bluntest, he says, “Humans consume water, discard it, poison it, waste it, and restlessly change the hydrological cycles, indifferent to the consequences: too many people, too little water, water in the wrong places and in the wrong amount. The human population is burgeoning, but water demand is increasing twice as fast.”

Thanks to de Villiers’s humane tone and nimble curiosity, Water ends on a progressive note, despite all its sobering and distressing information. There is much to be learned here, and all would profit if we began to act on Water’s lessons.
