World Water Day: Accelerating Change

World Water Day is 22 March 2023. This annual observance was organized by the United Nations in 1993 to focus attention on the importance of freshwater and to promote sustainable freshwater management. Each year a different theme is chosen, centered on topics relevant to clean water, sanitation and hygiene. The theme for 2023 is Accelerating Change. The UN World Water Development Report (WWDR) is also released each year around World Water Day.

I feel that the 2023 focus might be a misstep. Not that I don’t believe that we all could do better at using water, and I think that most of us could stand to be more aware of the true issues in water scarcity. But that is where “Be the Change” fails.

This message is a favorite fuzzy redirection ploy of the Davos set. It cheerily turns the blame and the responsibility upside-down. It says, if you want things to be different then get off your butt and do something. You specifically, not you collectively. And certainly not Us. (Or US…) But individuals can do very little about water distribution and over-harvest. This is not to say individuals can do nothing, but individuals are not those who are creating the most stress to water and weather systems. They can’t stop the problem. They can only adapt themselves to the problem — until there are no adaptation options left.

We are rather close to that tipping point in many regions of the world. Moreover, the problems are getting worse at an accelerating pace. If we want change — and we do because we will not survive without it — then those who are causing the problems need to change. We can put pressure on them to change. We can put pressure on politicians who can regulate change. We might even join the politicians and other organizations who can collectively force change. But…

We’ve been trying to force this top-down change for decades. Water scarcity is not a new problem. It is not even a newly devastating problem. Cadillac Desert, one of the most powerful descriptions of human water use folly, was first published in 1986 — as a history book! Though one that has proved uncannily prophetic in the almost 40 years since it was written…

The change is manifestly not something individuals can be. The problems are caused by our culture, our systems of industrial agriculture, our methods of mining natural gas and oil, our pollution and waste, and our ridiculous propensity to put large, thirsty population centers in arid climates — because it’s pretty and sunny and warm. Fixing water scarcity requires a complete overhaul of our systems, our desires and our thinking, and it mostly needs to happen among the industries and corporations who created and benefit most from all these disastrous policies.

This does not seem likely. In any case, it has not happened yet. But there is one change that individuals can be. One that will put the most pressure on the elites. One that will topple those elites and all their bad ideas. I call it ‘old lady activism’. It is how women (especially, but not exclusively) have kept human cultures alive for all the millennia of extractivist societies. We ignore the elites. We do not participate. We throw up our hands, turn our aching backs around, and walk away in disgust. Usually there is muttering. But there is always a refocus on real needs, on physical living, on being human.

If you want to be the change that will actually bring change, then leave. Get out of the system. When there is no labor and financial support for these activities, they will stop. They always have. Wars have been ended because people refused to fight, went home to feed their families. Civilizations have been decimated because slaves refused to work, melting into the countryside. Cultures have been preserved in the midst of destructive economics because housewives refused to follow rules, growing their own food and caring for their communities from the ‘powerless’ margins.

Old women can lead the way. We have that power. It doesn’t involve anything difficult. Just don’t go shopping. Don’t buy that latest gadget. Don’t turn on the ones you already have. Don’t throw away what works in favor of some shiny new thing. Don’t go galavanting all over the globe in search of something to fill up that empty place inside you. You can do a good deal of this necessary work just sitting in your comfy chair with a good book — from the library! — and a bowl of oatmeal — grown locally!

So today on World Water Day, you be that change. By all means, learn about the real issues (read on below). Fix the leaks in your life. If you have the resources, make yourself and your community more water-resilient. Maybe that entails leaving the desert. Maybe that means learning how to live in a desert. Certainly it means learning to live within the means of your lands wherever you are. But most importantly, do nothing. Stay home from work if you can. Do not gas up the car or buy veg that used up gallons of oil in getting to the supermarket. Don’t stare at a screen. Don’t generate waste. Do nothing today. And then make that a habit.

And if you must, muttering is a totally reasonable form of activism…

Hence this blog…

From the Book Cellar

If you want to learn more about water scarcity, read Cadillac Desert by Marc Reisner. Best primer there is. Reisner tells his tale in terms of the the US Southwest, but the problems he describes are global.

The futuristic novel, The Water Knife by Paolo Bacigalupi is also a good tutorial. The story is a dark look at where we are heading. Not where we may be heading — though maybe the solar-tech society that Bacigalupi envisioned is too hopeful now. But the underlying water tensions in his tale are real; he’s drawn an accurate logical progression from this present moment into the near future.

However, if you want to wallow in watery emotions and just be water for today, here is the soundtrack: Silencia by Hammock.

The Real Water Problem: Groundwater

Water is the other finite liquid resource that is increasingly becoming a challenge. Unlike petroleum, however, humans can’t live without water. Today around two-thirds of the global population – four billion people – face water scarcity for at least one month a year. As we head deeper into climate change that number will increase, and the intensity of the problem will increase also. Seasonal water scarcity will become long-term water stress which is the condition of not having sufficient water to meet needs. Increased stress will be concentrated in the arid regions of the Middle East, North Africa, south and central Asia, and the US Southwest. However, no region will be free from water worries; the humid US Midwest may face some level of water stress by 2050. And of course, we’ve already seen that even the temperate rain forests of the Pacific Northwest can succumb to heat and drought — and the associated disaster of uncontrolled fire.

Water availability is affected by physical conditions — such as rainfall, rate of evaporation, and land surface morphology — and human management — such as dams, groundwater extraction, and reservoirs. Climate change will likely affect local precipitation patterns as well as evaporation. Of the two, evaporation may be more critical. We tend to think of the water cycle as rainfall to river to ocean back to clouds, but in reality, evaporation is taking up water at every stage. Evaporation is largely driven by solar radiation and temperature. So climate change has the potential to greatly increase evaporation, leading to decreased flows in streams and rivers, less groundwater recharge, and shrinking reservoirs — perhaps even an inability to store water on the surface at all.

Water scarcity will also be affected by human management — of both water and other resources. As demands for energy outpace the availability of fossil fuels, there will be more calls for hydroelectric dams, though it is doubtful that there will be sufficient energy and resources to build these structures. There are also demands for more oil and natural gas production, especially so after Putin’s invasion of the Ukraine and the resulting economic sanctions on this fossil-fuel-rich region. Most conventional wells are now played out, so any increased production will come from hydro-fracking. However, with its intensive water use and then storage of waste in aquifers where toxins are free to migrate into drinking water supplies, fracking for gas or oil is a case of borrowing from one scarce resource to pay for another. Fracking converts potable water into toxic waste, a rather steep price to pay for energy. We can power down our lives. We can’t eliminate our water needs.

Worse yet, many fracked wells are located in the central part of the US, a place that produces a quarter of the nation’s crops, but which is underlain and supported by several ancient aquifers that are running dry. For example, the Ogallala Aquifer is a remnant of Pleistocene glacial meltwater. It receives scant recharge from surface water even when there is substantial rainfall, and agriculture is pumping this body of water much faster than it can be replenished. At current rates of use, it is predicted that the Ogallala will be 70% depleted — that is, water will be unobtainable — within a half century. Thirty percent of wells in Kansas have already run dry. Yet the intensively fracked Permian Basin sits right over this aquifer.

Shallow fracked wells affect groundwater substantially. Water quality is reduced and water levels are depleted in regions of fracking. And there is substantial overlap between the aquifers that are already being dangerously drawn down through other means and the regions with high concentrations of fracked wells. Fracking is creating even more freshwater scarcity in a region wracked by drought and over-use. We are literally poisoning the wells that we haven’t already drained dry.

Another fragility of freshwater supply comes from sea level rise and the increased strength of ocean storms, both brought on by climate change. The most immediate problem of coastal cities and climate change is not flooding as such, though that is the most visible expression of misery. What will soon force migration from these cities is the fact that potable water will be increasingly scarce. Water system infrastructure is built at current sea level, and groundwater, by definition, is below sea level. As seas rise and stronger storm surges throw more ocean water onto land, drinking water will be contaminated with salt and other pollutants, and this will happen long before the streets are flooded. There are springs in Florida — which relies on one of the most threatened aquifers in the world for its drinking water — that have already seen flows decreased by some 60%. As water pressure in this groundwater source is reduced by overuse combined with insufficient recharge, salt water is pulled into the aquifer. The results of this are predictably devastating.

Groundwater salinization is not a problem that can be solved with sea walls and other barriers. Nor is it limited to coastal regions. The Murray River basin in southeast Australia is seeing increasing salinity in surface waters due to a combination of prolonged drought and overuse. But testing of groundwater in this region is showing comparable salt contamination in underlying aquifers as well — because there is no surface water that is not in communication with groundwater (though there is quite a lot of groundwater that does not flow to the surface without human intervention). These are not two distinct systems but one connected flow of water both above and below ground.

So similarly, in regions of intensive industrial agriculture, the nitrates that are pouring into rivers and streams from fertilizer and fecal run-off, are also seeping into our groundwater reservoirs. The Water Boards of California have advised the state to directly address groundwater contamination in the Tulare Lake Basin because of nitrate run-off that flowed into aquifers decades ago. There are communities in this region that can neither afford to treat these contaminated waters nor locate other sources of drinking water. They are relying on wells poisoned by agricultural surface water pollution.

Nearly all of our liquid freshwater is groundwater. All rivers, streams and lakes combined make up a tiny fraction of a percent of total freshwater. We already rely on groundwater pumping to meet the majority of our freshwater needs. But there is so much water stored in subsurface aquifers that in many drought-stricken regions humans could, with better infrastructure and pollution control, rely on groundwater even in the absence of rainfall. It is estimated that much of the African continent is underlain by enough water to supply most countries through five years of drought, some by over half a century.

Of course, this water is only accessible through drilled wells, most of which require pumping (ie water pressure is not sufficient to force water to the surface in these wells). Furthermore, an increase in pumping over time results in lowering the water level in wells which then translates into a need for deeper wells and more powerful pumps. This cycle results in a continual stream of energy and resource flow necessary to tap into these reserves of water. It is hard to see how these flows will be maintained in a world of increasing scarcity, especially in poor communities. So while the water may be there for the taking, the ‘taking’ may not be there for the water. Still, the resources can be found if there is sufficient wealth in the search. And, in all fairness, those countries which have contributed most to climate instability should be assisting these countries who are most affected by that instability — which, of course, means that wealthy countries should be aiding others in drilling and maintaining these wells. So, with cooperation, increasing reliance on groundwater could be a short-term option to supply water in times of climate-driven drought.

However, nothing is a long term solution. This is a critical fact to remember. As in all finite resources, overuse will exhaust our groundwater supplies (especially when combined with pollution). In many regions this is already a problem, even in places with abundant recharge from rainfall. No place is immune to water scarcity. To underline this, consider that wells are running dry in New England these days. This happens because surface water from rainfall and snowmelt comes in short, intense bursts. Much of the water rapidly drains off the surface and quickly runs down to the ocean. It does not recharge groundwater reservoirs. It doesn’t even do a good job of recharging surface reservoirs in particularly warm summers with high evaporation — or simply high draw-down.

Before water-use restrictions were imposed in 1989, the Quabbin reservoir in central Massachusetts went through a twenty-year period of water use above safe-yield — that is, more water was taken out than could be replenished by precipitation and water flow into the basin. This resulted in dropping water levels in the reservoir and its surrounding region. Because water pressure is always lower on the surface, groundwater will flow to the surface if it can. So drawing down a lake is effectively pumping groundwater. There are wells in this region that are still dry over thirty years later.

Water scarcity will be a fact everywhere, even in a world of increasing warmth and therefore increasing precipitation. In places where the rain falls, it will come in strong storms, much of which will be lost to run-off. Groundwater will not be replenished and wells will run dry. And this as true for wet areas as it is for deserts.

So learn where your water is flowing from and where it is flowing to. How do you affect groundwater viability when you turn on the tap? Ultimately, every drop that flows down the drain is lost to the ocean. So what amount of rainfall recharge is available to groundwater in your region — and is it enough?

  1. Fascinating and informative read – I always look forward to your posts, enjoying the way you write and think about, well, everything. Perth in Western Australia has to desalinise sea water for one third of its drinking water. It’s largely built on old beach sand and suffers summer drought as part of a Mediterranean style climate. I live some 150 miles further south, still the same climate type but unlike Perth, most houses have some sort of water tank to collect rainwater from the roof to water vegetation during the hot dry summers and the watering is done through drip hoses on automatic timers. The 2 tanks on my daughter’s small (by Australian standards) farm contain 250,000 litres each and there are 4 ponds which, so far, have not dried out during even the hottest of summers. They are ‘off grid’ for water and sewerage. Water usage is now becoming part of community thought and policy in this small rural town.

  2. Where I live we are already acutely aware of the effects of water shortage. Our municipal water supply is switched off every night and we often don’t get any water at all for two or three days in a row. As it is, our local rain-supplied dams have been empty for years and we rely on water brought in from the Fish River (about 60km away). Water restrictions have remained in force for years and so – incredibly – many residents have sunk boreholes in their gardens to keep their lawns green and flowers flourishing. How they can be allowed to collectively tap the underground water resources – thus lowering the water table for everyone – under such circumstances is both wicked and self-centred. The rest of us drive dirty vehicles and pray for rain.

    1. I used to live in the desert. There are always tensions around the people who are transplanted there from humid climates for job reasons and so on. The cities want the industry and the growth so they look away on a lot of issues. Like watering a lawn where once only cacti lived. Or even waiving overwatering fees in certain developments that have home owner association covenants requiring a certain amount of grass in front of the house. Ridiculous… but…
