AI is an energy/water hog. Where is all the power coming from? plus UN defines new “era of global water bankruptcy”

I’ve touched on the topic of AI (artificial intelligence) and water consumption before, notably in my October 16, 2023 posting “The cost of building ChatGPT” where most of the focus is on the US. I now have some Canadian stories but first, there’s the United Nations University (UNU).

Global water bankruptcy

From a January 20, 2026 United Nations University press release (also on EurekAlert), Note 1: In the front pages, there’s this unexpected link to Canada : “UNU-INWEH [United Nations University Institute for Water, Environment and Health] gratefully acknowledges its host, the Government of Canada, and ongoing financial support from Global Affairs Canada.” Note 2: Links have been removed,

Amid chronic groundwater depletion, water overallocation, land and soil degradation, deforestation, and pollution, all compounded by global heating, a UN report today declared the dawn of an era of global water bankruptcy, inviting world leaders to facilitate “honest, science-based adaptation to a new reality.”

“Global Water Bankruptcy: Living Beyond Our Hydrological Means in the Post-Crisis Era,” argues that the familiar terms “water stressed” and “water crisis” fail to reflect today’s reality in many places: a post-crisis condition marked by irreversible losses of natural water capital and an inability to bounce back to historic baselines.

“This report tells an uncomfortable truth: many regions are living beyond their hydrological means, and many critical water systems are already bankrupt,” says lead author Kaveh Madani, Director of the UN University’s Institute for Water, Environment and Health (UNU-INWEH), known as ‘The UN’s Think Tank on Water.’

Expressed in financial terms, the report says many societies have not only overspent their annual renewable water “income” from rivers, soils, and snowpack, they have depleted long-term “savings” in aquifers, glaciers, wetlands, and other natural reservoirs.

This has resulted in a growing list of compacted aquifers, subsided land in deltas and coastal cities, vanished lakes and wetlands, and irreversibly lost biodiversity.

The UNU report is based on a peer-reviewed paper in the journal of Water Resources Management that formally defines water bankruptcy as

1) persistent over-withdrawal from surface and groundwater relative to renewable inflows and safe levels of depletion; and

2) the resulting irreversible or prohibitively costly loss of water-related natural capital.

By contrast:

  • “Water stress” reflects high pressure that remains reversible
  • “Water crisis” describes acute shocks that can be overcome

The report is issued prior to a high-level meeting in Dakar, Senegal (26–27 Jan.) to prepare the 2026 UN Water Conference, to be co-hosted by the United Arab Emirates and Senegal 2-4 Dec. in the UAE. 

While not every basin and country is water-bankrupt, Madani says, “enough critical systems around the world have crossed these thresholds. These systems are interconnected through trade, migration, climate feedbacks, and geopolitical dependencies, so the global risk landscape is now fundamentally altered.”

Madani underlines the following four essential points:

  • Water cannot be protected if we allow the hydrological cycle, the climate, and the underlying natural capital that produces water to be interrupted or damaged. The world has an important and still largely untapped strategic opportunity to act.
  • Water is an issue that crosses traditional political boundaries. It belongs to north and south, and to left and right. For that reason, it can serve as a bridge to create trust and unity between and within nations. In the fragmented world we live in, water can become a powerful focus for cooperation and for aligning national security with international priorities.
  • Investment in water is also investment in mitigating climate change, biodiversity loss, and desertification. Water should not be treated only as a downstream sector affected by other environmental crises. On the contrary, targeted investment in water can address the immediate concerns of communities and nations while also advancing the objectives of the Rio Conventions (climate, biodiversity, desertification).
  • A renewed global emphasis on water could help reaccelerate stalled negotiations and potentially reenergize halted international processes. A practical and cooperative focus on water offers a way to connect urgent local needs with long-term global goals.

Hotspots

In the Middle East and North Africa region, high water stress, climate vulnerability, low agricultural productivity, energy-intensive desalination, and sand and dust storms intersect with complex political economies;

In parts of South Asia, groundwater-dependent agriculture and urbanization have produced chronic declines in water tables and local subsidence; and

In the American Southwest, the Colorado River and its reservoirs have become symbols of over-promised water.

A world in the red

Drawing on global datasets and recent scientific evidence, the report presents a stark statistical overview of trends, the overwhelming majority caused by humans:

50%: Large lakes worldwide that have lost water since the early 1990s (with 25% of humanity directly dependent on those lakes)

50%: Global domestic water now derived from groundwater

40%+: Irrigation water drawn from aquifers being steadily drained

70%: Major aquifers showing long-term decline

410 million hectares: Area ofnatural wetlands – almost equal in size to the entire European Union – erased in the past five decades

30%+: Global glacier mass lost since 1970, with entire low- and mid-latitude mountain ranges expected to lose functional glaciers altogether within decades

Dozens: Major rivers that now fail to reach the sea for parts of the year

50+ years: How long many river basins and aquifers have been overdrawing their accounts

100 million hectares: Cropland damaged by salinization alone

And the human consequences:

75%: Humanity in countries classified as water-insecure or critically water-insecure

2 billion: People living on sinking ground.

25 cm: Annual drop being experienced by some cities

4 billion: People facing severe water scarcity at least one month every year

170 million hectares: Irrigated cropland under high or very high water stress – equivalent to the areas of France, Spain, Germany, and Italy combined

US$5.1 trillion: Annual value of lost wetland ecosystem services

3 billion: People living in areas where total water storage is declining or unstable, with 50%+ of global food produced in those same stressed regions.

1.8 billion: People living under drought conditions in 2022–2023

US$307 billion: Current annual global cost of drought

2.2 billion: People who lack safely managed drinking water, while 3.5 billion lack safely managed sanitation

Says Madani: “Millions of farmers are trying to grow more food from shrinking, polluted, or disappearing water sources. Without rapid transitions toward water-smart agriculture, water bankruptcy will spread rapidly.”

A new diagnosis for a new era

A region can be flooded one year and still be water bankrupt, he adds, if long-term withdrawals exceed replenishment. In that sense, water bankruptcy is not about how wet or dry a place looks, but about balance, accounting, and sustainability.

Says Madani: As with global climate change or pandemics, a declaration of global water bankruptcy does not imply uniform impact everywhere, but that enough systems across regions and income levels have become insolvent and crossed irreversible thresholds to constitute a planetary-scale condition.

“Water bankruptcy is also global because its consequences travel,” Madani explains. “Agriculture accounts for the vast majority of freshwater use, and food systems are tightly interconnected through trade and prices. When water scarcity undermines farming in one region, the effects ripple through global markets, political stability, and food security elsewhere. This makes water bankruptcy not a series of isolated local crises, but a shared global risk that demands a new type of response: Bankruptcy management,  not crisis management.”

A call to reset the global water agenda

The report warns that the current global water agenda – largely focused on drinking water, sanitation, and incremental efficiency improvements – is no longer fit for purpose in many places and calls for a new global water agenda that:

  • Formally recognizes the state of water bankruptcy
  • Recognizes water as both a constraint and an opportunity for meeting climate, biodiversity, and land commitments
  • Elevates water issues in climate, biodiversity, and desertification negotiations, development finance, and peacebuilding processes.
  • Embeds water-bankruptcy monitoring in global frameworks, using Earth observation, AI, and integrated modelling
  • Uses water as a catalyst to accelerate cooperation between the UN Member States

In practical terms, managing water bankruptcy requires governments to focus on the following priorities:

  • Prevent further irreversible damage such as wetland loss, destructive groundwater depletion, and uncontrolled pollution
  • Rebalance rights, claims, and expectations to match degraded carrying capacity
  • Support just transitions for communities whose livelihoods must change
  • Transform water-intensive sectors, including agriculture and industry, through crop shifts, irrigation reforms, and more efficient urban systems
  • Build institutions for continuous adaptation, with monitoring systems linked to threshold-based management

The report underlines that water bankruptcy is not merely a hydrological problem, but a justice issue with deep social and political implications requiring attention at the highest levels of government and multilateral cooperation. The burdens fall disproportionately on smallholder farmers, Indigenous Peoples, low-income urban residents, women and youth while the benefits of overuse often accrued to more powerful actors.

“Water bankruptcy is becoming a driver of fragility, displacement, and conflict,” says UN Under-Secretary-General Tshilidzi Marwala, Rector of UNU. “Managing it fairly – ensuring that vulnerable communities are protected and that unavoidable losses are shared equitably – is now central to maintaining peace, stability, and social cohesion.”

“Bankruptcy management requires honesty, courage, and political will,” Madani adds. “We cannot rebuild vanished glaciers or reinflate acutely compacted aquifers. But we can prevent further loss of our remaining natural capital, and redesign institutions to live within new hydrological limits.”

Upcoming milestones —  the 2026 and 2028 UN Water Conferences, the end of the Water Action Decade in 2028, and the 2030 SDG deadline, for example — provide critical opportunities to implement this shift, he says.

“Despite its warnings, the report is not a statement of hopelessness,” adds Madani. “It is a call for honesty, realism, and transformation.  Declaring bankruptcy is not about giving up — it is about starting fresh. By acknowledging the reality of water bankruptcy, we can finally make the hard choices that will protect people, economies, and ecosystems. The longer we delay, the deeper the deficit grows.”

AI data centre building spree in Canada (special emphasis: British Columbia [BC])

An October 18, 2025 article (with embedded videos) by Jonathan Montpetit and Yvette Brend with files from Tara Carman on Canadian Broadcasting Corporation’s (CBC) news online website,

On a dry, hot day this summer, Kathryn Barnwell, a retired English professor, marched up the road from her home in Nanaimo, B.C [British Columbia]., to take another crack at the mayor.

Leonard Krog, a longtime friend of Barnwell’s, was standing by the entrance to a parched wooded lot, the proposed site for a data centre Krog has been backing. 

“I really, really enjoin you to think about what this [data centre] could mean for your political career,” Barnwell said, barely looking him in the eye.

Krog, who has been mayor since 2018, sees the project as a chance to modernize the city’s economy.

“The kind of jobs that would be attracted to this kind of facility are the jobs of the future,” he said.

Until three years ago, Barnwell knew little about data centres, which house the computer servers that power much of the online world. But when the plot of land near her home was rezoned for one, she began researching. She’s now one of the loudest opponents of the project in Nanaimo.

Her main concern, shared by other local opponents, is the amount of municipal drinking water the 200,000-square foot data centre would need for its cooling system. In a region beset by drought, Barnwell says similar-sized facilities can churn through 70,000 litres of potable water a day.

“Life on this planet is sustained by water. It is not sustained by data. We don’t need data the way we need water,” Barnwell said. “And we in Canada have been pretty blithe about our natural resources.”

Barnwell sees herself as part of a global resistance movement drawing attention to the environmental impact of data centres, at a moment when the tech industry is spending dizzying sums to build them. 

It’s not just BC according to the October 18, 2025 article, Note: A link has been removed,

Canada is poised to join the data centre boom. The federal government, and some provinces, have been actively courting investors, vaunting the country’s cheap electricity (much of it hydro power) and cool climate. 

At least eight projects are underway to build hyperscale data centres in Canada, according to the federal government. But as such projects face greater scrutiny around the world, Canada is jumping into the AI construction race with few mechanisms to protect its water supply.

“There’s barely any regulation in place,” said Geoff White, executive director of the Public Interest Advocacy Centre, an Ottawa-based consumer protection group.

Microsoft builds out in Canada

Among the big tech companies, Microsoft has taken the lead in building data centres with AI capacity in Canada. The Washington-based corporation purchased seven large tracts of land in 2021, including a golf course near Quebec City and a former department store in the Toronto suburb of Etobicoke. 

It’s in the process of turning the sites into data centres capable of powering its AI-enabled products like Azure and Copilot, an investment worth at least $1 billion.

At least two of the Microsoft data centres in Ontario have been cleared by municipal authorities to consume vast amounts of municipal drinking water.

The Etobicoke data centre, dubbed YTO 40, was approved to use up to 39.75 litres of water per second for cooling purposes, according to planning documents submitted to the city. That would be the equivalent of around 1.2 billion litres a year, or 500 Olympic-sized swimming pools. 

A Microsoft data centre complex in nearby Vaughan, a city spokesperson said, is expected to consume 730 million litres of water annually. 

But according to Microsoft, its new Canadian data centres will only use a fraction of that amount, because of design features that allow them to be cooled using outdoor air and recycled rainwater. 

Alistair Speirs, general manager of Microsoft’s Azure global infrastructure, acknowledges traditional industrial cooling has “been a very water-intensive process.” He says the way Microsoft is building its data centres today is “with really that in mind.” 

“One of the great things about building in Canada, and in colder climates, is that we can just use free air cooling from outside air temperatures.”

The company said its data centres will only draw municipal water when outside temperatures are above 29.4 C or when indoor humidity levels drop below five per cent. 

Microsoft has made similar promises elsewhere. The company built a data centre in the northwestern Netherlands despite opposition from local farmers, promising it would only need between 12 and 20 million litres of water annually. 

Dutch media later revealed the data centre was consuming more than four times that — as locals were being asked to limit their own water use. 

In its response to Dutch media, Microsoft said the initial estimate had been based on “consumption at that time,” but did not specify what time period it was referring to.

Growing concerns and protests but not so much in Canada, from the October 18, 2025 article, Note: A link has been removed,

The new Microsoft data centres in Canada, which are slated to come online in the coming months, have faced no discernible opposition from the public. One Etobicoke city councillor wasn’t even aware of the YTO 40 project before CBC News contacted him.

That’s in stark contrast to communities in the United States, Europe and Latin America, where concerns about water scarcity have sparked protests.

Last month, Google shelved plans to build a $1-billion US data centre in Indianapolis, Ind., after residents organized a months-long campaign against the project. When a lawyer representing Google abruptly announced the decision at a city council meeting, the room erupted in applause that lasted for nearly a minute.

A growing number of jurisdictions in the U.S. and Europe are also seeking to pass regulations that would limit data centre water consumption or force companies to be more transparent about how much they’re using. 

Canada’s federal government has set aside $700 million to fund data centre projects here. But aside from energy regulators, who review data centre applications to connect to power grids, there is little industry oversight.

“If we’re racing ahead and thinking only about the economic benefits, and not thinking about the downstream impacts to our environment, that’s negligent,” said White with the Public Interest Advocacy Centre. “I think Canadians ought to be concerned. Our water is highly sought after, and will be as the world gets hotter.”

Elsewhere in the October 18, 2025 article, there’s information about water use in data centres,

How much water do chatbots drink?

Data centres are as old as computers and until recently were relatively uncontroversial — boring bits of IT infrastructure tucked away in non-descript office spaces.

But with the advent of cloud computing in the mid-2000s, they dramatically increased in size. 

These data centres — buildings ranging anywhere from 10,000 to 100,000 square feet — required upwards of 100 megawatts of power and millions of litres of water annually for their cooling systems.

These demands have only been turbocharged by artificial intelligence, which requires data centres that house thousands of densely packed high-performance chips, operating around the clock — and generating heat.

A study done in 2023 estimated that generating between 10 and 50 medium-sized responses in ChatGPT — the AI-powered chatbot — consumed about 500 millilitres of water. That accounts for both the water required to produce the electricity needed to run the data centre (435 millilitres) and cool it down (the remaining 65 millilitres).

A separate study, conducted by the International Energy Agency, estimated that in 2023, data centres around the world consumed around 140 billion litres of water just for cooling. 

Much of that was potable water pulled from municipal utilities. (Because data centres generally use evaporative cooling systems, untreated water can damage the sensitive computer equipment inside.)

If you have time, the October 18, 2025 article is worth reading in its entirety.

This October 15, 2025 article by Amanda Follett Hosgood for The Tyee is focused on BC’s approach to AI water consumption, Note: Links have been removed,

B.C. recently saw its first AI data centres open in Prince George and Kamloops, and more are on the way. AI centres have been touted as a way to grow the economy while ensuring data sovereignty by storing information within our borders.

“AI is everywhere. It’s changing how we work. It’s changing how we learn. It’s changing how we do business,” said Port Moody-Burquitlam MLA Rick Glumac, who this summer became B.C.’s minister of state for artificial intelligence and new technologies. The position comes with a mandate to expand B.C.’s AI sector.

“There’s a lot of good work ahead,” Glumac, who comes from a tech background [emphases mine], told The Tyee.

But there’s a hitch. AI is just one of various potential boom industries vying for a piece of B.C.’s limited electricity supply.

AI data centres are energy intensive, requiring immense amounts of electricity for power and cooling. B.C.’s hydroelectric grid, which is fed almost entirely by renewable sources, offers a clean — but limited — energy source that’s attractive to businesses seeking to market themselves as environmentally conscious.

As the province looks to green the existing economy, transition to electric vehicles and expand industries like LNG using cleaner energy, AI is fast becoming one more customer seeking a piece of the power pie.

Glumac’s technical background? From the Rick Glumac Wikipedia entry, Note: Links have been removed,

Glumac worked much of his career in the field of computer graphics as a software developer, visual effects artist, and computer graphics supervisor.[8]  He worked on the first computer-animated TV show ReBoot, and later worked for companies such as DreamWorks and Electronic Arts on well-known Hollywood films such as Shrek 2, Madagascar, and Over the Hedge.[8] Following this he developed apps for the iPhone.[7]

That’s a bit of leap for Mr. Glumac. Developing computer graphics is not the same thing as shepherding new and emerging technologies through government regulations and creating new regulations, deaing with public hopes/fears, anticipating energy needs, and dealing with any unintended consequences of the technologies themselves.

Follett Hosgood’s October 15, 2025 article provides an overview of the energy and data centre situation in BC,

B.C. is the first province in Canada to create a cabinet position dedicated to AI. But the province isn’t alone in signalling its interest in the industry.

The federal government created its own minister of artificial intelligence and digital innovation following the spring election, tapping former broadcaster Evan Solomon for the position.

B.C.’s parallel cabinet position “gives us the opportunity to really put a focus on this and to partner with the federal government,” Glumac told The Tyee.

In an email, B.C.’s Ministry of Energy and Climate Solutions said the province groups data centres into three categories: conventional data centres, cryptocurrency mining and AI data centres.

It added that there are currently 12 “notable” conventional data centres in the province and three more requesting a power connection. If approved, the combined operations would draw nearly 40 megawatts of power — a small slice of the province’s 12,000-megawatt power supply.

AI data centres, however, can each draw more than 100 megawatts of power.

Two of Canada’s largest telecommunications companies recently announced plans to open AI data centres in B.C.

In May [2025], Bell Canada said it would open an AI “data centre supercluster” that is expected to use upwards of 500 megawatts, or about five per cent of the province’s current power supply.

Its first AI data centre, a seven-megawatt facility in Kamloops, opened in June. A second seven-megawatt facility is slated to open in Merritt by the end of next year.

The company is planning two additional 26-megawatt data centres in the near future, one in partnership with Thompson Rivers University and the other with the Upper Nicola Band. It says another two data centres with a combined capacity of more than 400 megawatts are in “advanced planning stages.”

Bell declined to provide detailed timelines, confirming in an email only that its Kamloops site is currently operational. “We remain on track and more sites will open in the coming months,” a spokesperson wrote.

The company also faces competition.

In April [2025], Telus announced two Canadian data centres, one in B.C., touting the operations as “fully owned, operated and secured on Canadian soil by a Canadian company” — a nod to national concerns over data sovereignty.

The Kamloops operation will be “powered by 99 per cent renewable energy,” Telus said, but how much power it will draw is unclear. The company didn’t respond to The Tyee’s questions about capacity or when it might come online.

Asked about how these data centres will fit into B.C.’s power grid, Glumac said that “BC Hydro is monitoring this very closely and planning accordingly.” The industry is evolving quickly, he added, and he wouldn’t rule out the possibility that the province would need to regulate expansion as it did with cryptocurrency mining.

“We want to make sure that clean energy supports not just data centres but supports the people in British Columbia and supports economic opportunities and job opportunities,” Glumac said. “It’s very important to monitor that and to balance all of that, and BC Hydro is doing that.”

BC Hydro directed The Tyee’s questions to B.C.’s Energy Ministry, which also provided an emailed statement.

“BC Hydro continues to look at how the growth in the industry could impact future demand, and will adjust its forecasts and planning accordingly,” a ministry spokesperson wrote, adding that the province is committed to “balancing energy demand with economic priorities.”

“We recognize that the AI industry is evolving rapidly, and we are closely monitoring how advancements in AI infrastructure may impact future energy needs.”

AI data centres don’t have to be a problem

It’s not all doom and gloom, from Follett Hosgood’s October 15, 2025 article,

Last year, the province [BC] imported a quarter of its electricity needs, most of it from the United States and Alberta, where it was generated using fossil fuels. In both 2024 and earlier this year, BC Hydro put out calls for power in an effort to make up the shortfall with clean, locally produced power.

Kate Harland is the research lead for clean growth at the Canadian Climate Institute. In an interview with The Tyee, she said that now is the time for governments to plan for the expected spike in energy demand from AI data centres.

“There is a lot of interest right now across Canada in having AI-enabled data centres,” Harland said. But she added that there’s likely to be a “tipping point” where AI’s benefits might not outweigh its demands on the power grid.

“If suddenly data centres are 20 per cent or 30 per cent of your total electricity demand, then you get into a new territory of questions,” she said.

While provinces such as B.C. and Quebec have traditionally taken a “first come, first served” approach to industrial power requests, some jurisdictions are implementing new rules to ensure limited power supply is allocated fairly and for the greatest overall benefit, Harland said.

Last year [2024], Quebec began requiring any projects requesting more than five megawatts of power to get ministerial approval. The approval considers factors such as economic impact, social impact and power requirements.

In 2023, Quebec’s government also signed an agreement with Microsoft as it launched four new data centres in the province. The tech giant agreed to reduce its energy consumption by 30 per cent during times of peak power use.

Harland said the pressure to meet power demand could be approached as an opportunity to build out renewables and increase supply. If data centres become more efficient over time, that would free up renewable power for domestic uses like electric vehicles and heat pumps, she said.

AI is also credited with identifying efficiencies, including in power use, which could help to offset its draw on the grid, Harland said. (Glumac also pointed to a recent study indicating that it could drive $200 billion in productivity improvements nationally.)

The technology’s practical uses tend to set it apart from cryptocurrency in the discussion about which industries get priority to grid access, Harland said.

The potential for data sovereignty is another argument in its favour.

But Harland emphasized that now is the time for governments to be proactive in forming AI policies.

If you have the time, do read Follett Hosgood’s October 15, 2025 article in its entirety.

If you have even more time, I provided some detail about the federal government and its new Minister of AI Digital Innovation in an October 17, 2025 posting (scroll down to the Canada and its Minister of AI and Digital Innovation subhead for information about Evan Solomon, the new minister. If you continue further in the posting.

What about local governments?

Municipalities may also have a role to play as data centres become more important in their real estate markets as this January 31, 2026 article by Kenneth Chan for the Daily Hive could be said to hint at, Note: Links have been removed,

Westbank’s major downtown Vancouver office tower project at steam plant site pivots to hotel, residential, and data centre uses

One of downtown Vancouver’s largest office development projects, first planned during the pre-pandemic office market boom, will not proceed as originally approved [emphasis mine], given the prevailing weak office market conditions.

Instead, the office tower project previously approved for 150 West Georgia St. (formerly addressed as 720 Beatty St.) — situated at the southwest corner of Beatty Street and West Georgia Street, immediately adjacent to BC Place Stadium’s northeast corner — is now in the very early stages of being repositioned as a mixed-use hotel and residential tower with a data centre [emphases mine], based on an all-new architectural design concept that also adds density and height.

A number of preliminary conceptual artistic renderings also show this drastic pivot.

All of this will be integrated into the district utility company Creative Energy’s new on-site replacement and expanded steam plant facilities, which have incurred major cost increases and experienced delays, including factors related to local developer Westbank’s liquidity challenges.

Pivot to a new tower with hotel, residential, and data centre uses on top of the Creative Energy facility

In October 2020, Vancouver City Council approved Westbank’s original rezoning application for redeveloping this site into an office tower and a standalone entertainment pavilion building, with below-grade parking and a new replacement steam plant.

Moving forward, essentially everything below grade — including the new vehicle parking and the Creative Energy facility — as well as the new entertainment pavilion building, will remain unchanged, while the office tower project above grade will not proceed.

Instead, the previous 264-ft.-tall, 17-storey, bulky, S-shaped office tower concept — designed by Bjarke Ingels Group and HCMA — with 583,000 sq. ft. of office space and 12,000 sq. ft. of additional ground-level retail/restaurant space has been completely scrapped and is now envisioned to become a 450-ft-tall, 48-storey, mixed-use hotel and residential tower with a data centre and ground-level retail/restaurant space, for a total of roughly 700,000 sq. ft. of building floor area.

The significantly increased height for added density is made possible by City Council’s July 2023-approved sweeping city-wide changes [emphasis mine] to the protected mountain view cones. Design revisions for taller heights are also set to occur for the nearby future Plaza of Nations and Concord Landing projects, made possible by these view cone changes.

… a Westbank spokesperson previously confirmed to Daily Hive Urbanized that they are looking into adding major data centre uses [emphasis mine] to the 1977-built, six-storey office building at 111 East 5th Ave. This distinctive brick building — part of Westbank’s Main Alley tech campus of new and renovated office buildings in the vicinity of the intersection of Main Street and East 5th Avenue in Mount Pleasant — is perhaps best known for being one of Hootsuite’s office locations since 2014. Westbank noted that at this time, Hootsuite is still the building’s primary tenant.

How will these and future data centres affect Vancouverites’ energy needs and access to water?.Hopefully, someone in Vancouver’s city government is doing some thinking on these matters.

Sixth Japan SciCom (science communication) Forum (JSF 2024) comes to Fukuoka on October 22-23, 2024

I have more information here in an August 9, 2024 Japan SciCom Forum press release on EurekAlert,

On October 22 and 23 [2024], the sixth Japan SciCom Forum Conference (JSF 2024) will be held at Kyushu University’s Ito Campus. Fukuoka will become the third city, following Tokyo and Okinawa, to welcome specialists in science communication from Japan and around the world.

JSF 2024 will bring together a diverse group of science communicators, writers, researchers, and journalists, along with experts from overseas. The conference is open to anyone involved in sharing research findings internationally, as well as those interested in science communication, public outreach, and engagement.

This year’s JSF will explore a wide range of topics, including crisis management, video production, and the use of AI in science communication. There will also be a focus on advancing inclusion and co-creation through varied communication channels. 

“We are delighted to host JSF 2024 at Kyushu University and warmly welcome researchers and communicators from diverse backgrounds,” said Satoko Kanzaki, Executive Vice President of Communications and Public Relations at Kyushu University. “Science communication is essential not only for researchers but also for fostering a two-way dialogue between researchers and the public, encouraging society as a whole to engage with scientific topics. As we look to the future, it is important to explore the impact of science and technology on society, considering not only their benefits but also their ethical, legal, and social implications. We hope this two-day conference will serve as a platform to deepen discussions on science communication and contribute to its continued advancement.”

Japan SciCom Forum is a platform for individuals involved in science communication and outreach from Japan, with a global focus. During the two-day conference this year, the keynotes will address the challenges of science communication, while workshops will offer practical insights and skills for outreach. Additionally, there will be opportunities throughout the program for participants to engage in discussions and networking. 

“The Japan SciCom Forum is more than just a conference; it’s a platform for collaboration and innovation in science communication. This year’s event in Fukuoka will highlight the dynamic ways we can engage with diverse audiences and bring science to the forefront of public discourse,” said Thilina Heenatigala from the Earth-Life Science Institute (ELSI) and member of the JSF organizing team. 

Ayumi Koso, from the National Institute of Genetics (NIG) and a JSF organizing team member added, “It’s a pleasure to bring the Japan Scicom Forum conference to another region in Japan. This year’s two-day conference offers plenty of time to socialize, and I look forward to seeing both new and familiar faces in Fukuoka!”

Registration is 1,000 yen and the event will be in English. Participants from outside Japan are welcome. For program and registration information please see here: JSF 2024

Desalination and toxic brine

Have you ever wondered about the possible effects and impact of desalinating large amounts of ocean water? It seems that some United Nations University (UNU) researchers have asked and are beginning to answer that question. The following table illustrates the rise in desalination plants and processes,


Today 15,906 operational desalination plants are found in 177 countries. Almost half of the global desalination capacity is located in the Middle East and North Africa region (48 percent), with Saudi Arabia (15.5 percent), the United Arab Emirates (10.1 percent) and Kuwait (3.7 percent) being both the major producers in the region and globally. Credit: UNU-INWEH [downloaded from http://inweh.unu.edu/un-warns-of-rising-levels-of-toxic-brine-as-desalination-plants-meet-growing-water-needs/]

A January 14, 2019 news item on phys.org highlights the study on desalination from the UNU,

The fast-rising number of desalination plants worldwide—now almost 16,000, with capacity concentrated in the Middle East and North Africa—quench a growing thirst for freshwater but create a salty dilemma as well: how to deal with all the chemical-laden leftover brine.

In a UN-backed paper, experts estimate the freshwater output capacity of desalination plants at 95 million cubic meters per day—equal to almost half the average flow over Niagara Falls.
For every litre of freshwater output, however, desalination plants produce on average 1.5 litres of brine (though values vary dramatically, depending on the feedwater salinity and desalination technology used, and local conditions). Globally, plants now discharge 142 million cubic meters of hypersaline brine every day (a 50% increase on previous assessments).

That’s enough in a year (51.8 billion cubic meters) to cover Florida under 30.5 cm (1 foot) of brine.

The authors, from UN University’s Canadian-based Institute for Water, Environment and Health [at McMaster University], Wageningen University, The Netherlands, and the Gwangju Institute of Science and Technology, Republic of Korea, analyzed a newly-updated dataset—the most complete ever compiled—to revise the world’s badly outdated statistics on desalination plants.

And they call for improved brine management strategies to meet a fast-growing challenge, noting predictions of a dramatic rise in the number of desalination plants, and hence the volume of brine produced, worldwide.

A January 14, 2017 UNU press release, which originated the news item, details the findings,

The paper found that 55% of global brine is produced in just four countries: Saudi Arabia (22%), UAE (20.2%), Kuwait (6.6%) and Qatar (5.8%). Middle Eastern plants, which largely operate using seawater and thermal desalination technologies, typically produce four times as much brine per cubic meter of clean water as plants where river water membrane processes dominate, such as in the US.

The paper says brine disposal methods are largely dictated by geography but traditionally include direct discharge into oceans, surface water or sewers, deep well injection and brine evaporation ponds.

Desalination plants near the ocean (almost 80% of brine is produced within 10km of a coastline) most often discharge untreated waste brine directly back into the marine environment.

The authors cite major risks to ocean life and marine ecosystems posed by brine greatly raising the salinity of the receiving seawater, and by polluting the oceans with toxic chemicals used as anti-scalants and anti-foulants in the desalination process (copper and chlorine are of major concern).

“Brine underflows deplete dissolved oxygen in the receiving waters,” says lead author Edward Jones, who worked at UNU-INWEH, and is now at Wageningen University, The Netherlands. “High salinity and reduced dissolved oxygen levels can have profound impacts on benthic organisms, which can translate into ecological effects observable throughout the food chain.”

Meanwhile, the paper highlights economic opportunities to use brine in aquaculture, to irrigate salt tolerant species, to generate electricity, and by recovering the salt and metals contained in brine — including magnesium, gypsum, sodium chloride, calcium, potassium, chlorine, bromine and lithium.

With better technology, a large number of metals and salts in desalination plant effluent could be mined. These include sodium, magnesium, calcium, potassium, bromine, boron, strontium, lithium, rubidium and uranium, all used by industry, in products, and in agriculture. The needed technologies are immature, however; recovery of these resources is economically uncompetitive today.

“There is a need to translate such research and convert an environmental problem into an economic opportunity,” says author Dr. Manzoor Qadir, Assistant Director of UNU-INWEH. “This is particularly important in countries producing large volumes of brine with relatively low efficiencies, such as Saudi Arabia, UAE, Kuwait and Qatar.”

“Using saline drainage water offers potential commercial, social and environmental gains. Reject brine has been used for aquaculture, with increases in fish biomass of 300% achieved. It has also been successfully used to cultivate the dietary supplement Spirulina, and to irrigate forage shrubs and crops (although this latter use can cause progressive land salinization).”

“Around 1.5 to 2 billion people currently live in areas of physical water scarcity, where water resources are insufficient to meet water demands, at least during part of the year. Around half a billion people experience water scarcity year round,” says Dr. Vladimir Smakhtin, a co-author of the paper and the Director of UNU-INWEH, whose institute is actively pursuing research related to a variety of unconventional water sources.

“There is an urgent need to make desalination technologies more affordable and extend them to low-income and lower-middle income countries. At the same time, though, we have to address potentially severe downsides of desalination — the harm of brine and chemical pollution to the marine environment and human health.”

“The good news is that efforts have been made in recent years and, with continuing technology refinement and improving economic affordability, we see a positive and promising outlook.”

¹The authors use the term “brine” to refer to all concentrate discharged from desalination plants, as the vast majority of concentrate (>95%) originates from seawater and highly brackish groundwater sources.

Earth Day, Water Day, and every day

I’m blaming my confusion on the American Chemical Society (ACS) which seemed to be celebrating Earth Day on April 15, 2014 as per its news release highlighting their “Chemists Celebrate Earth Day” video series  while in Vancouver, Canada, we’re celebrating it on April 26, 2014 and elsewhere it seems to be on April 20, this year. Regardless, here’s more about how chemist’s are celebrating from the ACS news release,

Water is arguably the most important resource on the planet. In celebration of Earth Day, the American Chemical Society (ACS) is showcasing three scientists whose research keeps water safe, clean and available for future generations. Geared toward elementary and middle school students, the “Chemists Celebrate Earth Day” series highlights the important work that chemists and chemical engineers do every day. The videos are available at http://bit.ly/CCED2014.

The series focuses on the following subjects:

  • Transforming Tech Toys– Featuring Aydogan Ozcan, Ph.D., of UCLA: Ozcan takes everyday gadgets and turns them into powerful mobile laboratories. He’s made a cell phone into a blood analyzer and a bacteria detector, and now he’s built a device that turns a cell phone into a water tester. It can detect very harmful mercury even at very low levels.
  • All About Droughts – Featuring Collins Balcombe of the U.S. Bureau of Reclamation: Balcombe’s job is to keep your drinking water safe and to find new ways to re-use the water that we flush away everyday so that it doesn’t go to waste, especially in areas that don’t get much rain.
  • Cleaning Up Our Water – Featuring Anne Morrissey, Ph.D., of Dublin City University: We all take medicines, but did you know that sometimes the medicine doesn’t stay in our bodies? It’s up to Anne Morrissey to figure out how to get potentially harmful pharmaceuticals out of the water supply, and she’s doing it using one of the most plentiful things on the planet: sunlight.

Sadly, I missed marking World Water Day which according to a March 21, 2014 news release I received was being celebrated on Saturday, March 22, 2014 with worldwide events and the release of a new UN report,

World Water Day: UN Stresses Water and Energy Issues 

Tokyo Leads Public Celebrations Around the World

Tokyo — March 21 — The deep-rooted relationships between water and energy were highlighted today during main global celebrations in Tokyo marking the United Nations’ annual World Water Day.

“Water and energy are among the world’s most pre-eminent challenges. This year’s focus of World Water Day brings these issues to the attention of the world,” said Michel Jarraud, Secretary-General of the World Meteorological Organization and Chair of UN-Water, which coordinates World Water Day and freshwater-related efforts UN system-wide.

The UN predicts that by 2030 the global population will need 35% more food, 40% more water and 50% more energy. Already today 768 million people lack access to improved water sources, 2.5 billion people have no improved sanitation and 1.3 billion people cannot access electricity.

“These issues need urgent attention – both now and in the post-2015 development discussions. The situation is unacceptable. It is often the same people who lack access to water and sanitation who also lack access to energy, ” said Mr. Jarraud.

The 2014 World Water Development Report (WWDR) – a UN-Water flagship report, produced and coordinated by the World Water Assessment Programme, which is hosted and led by UNESCO – is released on World Water Day as an authoritative status report on global freshwater resources. It highlights the need for policies and regulatory frameworks that recognize and integrate approaches to water and energy priorities.

WWDR, a triennial report from 2003 to 2012, this year becomes an annual edition, responding to the international community’s expression of interest in a concise, evidence-based and yearly publication with a specific thematic focus and recommendations.

WWDR 2014 underlines how water-related issues and choices impact energy and vice versa. For example: drought diminishes energy production, while lack of access to electricity limits irrigation possibilities.

The report notes that roughly 75% of all industrial water withdrawals are used for energy production. Tariffs also illustrate this interdependence: if water is subsidized to sell below cost (as is often the case), energy producers – major water consumers – are less likely to conserve it.  Energy subsidies, in turn, drive up water usage.

The report stresses the imperative of coordinating political governance and ensuring that water and energy prices reflect real costs and environmental impacts.

“Energy and water are at the top of the global development agenda,” said the Rector of United Nations University, David Malone, this year’s coordinator of World Water Day on behalf of UN-Water together with the United Nations Industrial Development Organization (UNIDO).

“Significant policy gaps exist in this nexus at present, and the UN plays an instrumental role in providing evidence and policy-relevant guidance. Through this day, we seek to inform decision-makers, stakeholders and practitioners about the interlinkages, potential synergies and trade-offs, and highlight the need for appropriate responses and regulatory frameworks that account for both water and energy priorities. From UNU’s perspective, it is essential that we stimulate more debate and interactive dialogue around possible solutions to our energy and water challenges.”

UNIDO Director-General LI Yong, emphasized the importance of water and energy for inclusive and sustainable industrial development.

“There is a strong call today for integrating the economic dimension, and the role of industry and manufacturing in particular, into the global post-2015 development priorities. Experience shows that environmentally sound interventions in manufacturing industries can be highly effective and can significantly reduce environmental degradation. I am convinced that inclusive and sustainable industrial development will be a key driver for the successful integration of the economic, social and environmental dimensions,” said Mr. LI.

Rather unusually, Michael Bergerrecently published two Nanowerk Spotlight articles about water (is there theme, anyone?) within 24 hours of each other. In his March 26, 2014 Spotlight article, Michael Berger focuses on graphene and water remediation (Note: Links have been removed),

The unique properties of nanomaterials are beneficial in applications to remove pollutants from the environment. The extremely small size of nanomaterial particles creates a large surface area in relation to their volume, which makes them highly reactive, compared to non-nano forms of the same materials.

The potential impact areas for nanotechnology in water applications are divided into three categories: treatment and remediation; sensing and detection: and pollution prevention (read more: “Nanotechnology and water treatment”).

Silver, iron, gold, titanium oxides and iron oxides are some of the commonly used nanoscale metals and metal oxides cited by the researchers that can be used in environmental remediation (read more: “Overview of nanomaterials for cleaning up the environment”).

A more recent entrant into this nanomaterial arsenal is graphene. Individual graphene sheets and their functionalized derivatives have been used to remove metal ions and organic pollutants from water. These graphene-based nanomaterials show quite high adsorption performance as adsorbents. However they also cause additional cost because the removal of these adsorbent materials after usage is difficult and there is the risk of secondary environmental pollution unless the nanomaterials are collected completely after usage.

One solution to this problem would be the assembly of individual sheets into three-dimensional (3D) macroscopic structures which would preserve the unique properties of individual graphene sheets, and offer easy collecting and recycling after water remediation.

The March 27, 2014 Nanowerk Spotlight article was written by someone at Alberta’s (Canada) Ingenuity Lab and focuses on their ‘nanobiological’ approach to water remediation (Note: Links have been removed),

At Ingenuity Lab in Edmonton, Alberta, Dr. Carlo Montemagno and a team of world-class researchers have been investigating plausible solutions to existing water purification challenges. They are building on Dr. Montemagno’s earlier patented discoveries by using a naturally-existing water channel protein as the functional unit in water purification membranes [4].

Aquaporins are water-transport proteins that play an important osmoregulation role in living organisms [5]. These proteins boast exceptionally high water permeability (~ 1010 water molecules/s), high selectivity for pure water molecules, and a low energy cost, which make aquaporin-embedded membrane well suited as an alternative to conventional RO membranes.

Unlike synthetic polymeric membranes, which are driven by the high pressure-induced diffusion of water through size selective pores, this technology utilizes the biological osmosis mechanism to control the flow of water in cellular systems at low energy. In nature, the direction of osmotic water flow is determined by the osmotic pressure difference between compartments, i.e. water flows toward higher osmotic pressure compartment (salty solution or contaminated water). This direction can however be reversed by applying a pressure to the salty solution (i.e., RO).

The principle of RO is based on the semipermeable characteristics of the separating membrane, which allows the transport of only water molecules depending on the direction of osmotic gradient. Therefore, as envisioned in the recent publication (“Recent Progress in Advanced Nanobiological Materials for Energy and Environmental Applications”), the core of Ingenuity Lab’s approach is to control the direction of water flow through aquaporin channels with a minimum level of pressure and to use aquaporin-embedded biomimetic membranes as an alternative to conventional RO membranes.
