This post (my first on this forum!) was mostly based on my recent read of a report from the UN University Institute for Water, Environment and Health (UNU-INWEH) released in January this year[1], and some adjacent content. My intent is only to raise a question to a broad, knowledgeable and critical EA-wired audience. The length of the post comes from the necessary description of what lead me to have this question.
Water-related issues are nothing new. Severe droughts impacting crop yields[2], floods forcing entire populations to flee as refugees[3], polluted rivers altering local food production or simply damaging local people's health[4], etc. are all catastrophes we hear of and for most of which, whether emergencies or chronic situations, the UN, humanitarian organizations and local governments try to act[5]. And from what I know, the EA community has also engaged under the broader umbrella of Global Health and Development (GHD).[6]
As illustrated by the examples above, water-related problems are diverse in nature (freshwater scarcity, lack of irrigation resources, polluted drinking water, etc.) and vary by local context (regional climate, presence of water streams and aquifers, local industry, local politics, etc.). This calls for different types of intervention depending on the issue and the local situation, and as such, it makes sense to approach these issues separately, evaluating interventions based on their specific cost-effectiveness and tractability.
This post is not arguing against that approach, nor claiming EA or GHD charities are unaware of water-related issues, nor their systemic causes (though as often, systemic level action may be less tractable). Rather, I want to present the hypothesis that what may be neglected is the civilizational risk character poised by water problems’ systemic causes. And by civilizational, I mean not existential to humanity, but which threatens, systemically, global human development and life condition improvements for generations.
This hypothesis came to me when I tried to observe natural water systems, resources and human uses as a unified globalized water system. Under those glasses, I felt that such system could collapse and lead to numerous cascading bad consequences. At least, to my understanding. So let’s dig in.
First, the read of the flagship report led by Dr. Kaveh Madani released by the UNU-INWEH in January 2026 helped me watch through these glasses. For decades, scientists and policymakers warned of a "global water crisis", implying a temporary shock followed by recovery. But in this UNU-INWEH report, the argument is that this framing is misleading[1]:
"The language of crisis—suggesting a temporary emergency followed by a return to normal through mitigation efforts—no longer captures what is happening in many parts of the world."
Instead, the report claims humanity has entered a state of "Global Water Bankruptcy": a permanent, systemic failure where the natural capital needed for recovery has been liquidated. In the report’s own words:
“The report calls for the recognition of the state of 'Water bankruptcy' as a persistent post-crisis condition of a human–water system in which longterm water use has exceeded renewable inflows and safe depletion limits, causing irreversible or effectively irreversible degradation such that previous levels of water supply and ecosystem functions cannot realistically be restored.”
This represents a fundamental conceptual shift: we are no longer managing temporary or local (even though chronic) failures but a persistent and global failure state requiring bankruptcy management rather than crisis response[1].
Let’s highlight two points:
Madani uses financial terminology to describe this catastrophic environmental reality: "In finance, when you spend more than you earn for too long, you go bankrupt."[7] The report declares a situation of water bankruptcy if characterized by both[1]:
The report consistently uses the adjective "global", placing its conclusions at worldwide scale. The data supports this[1]:
Now, not every water basin is water-bankrupt; however, the report claims too many critical systems around the world are, and due to their interconnected nature through trade, migration, climate feedbacks, and geopolitical dependencies, “the global risk landscape is now fundamentally altered”[1].
This is what I believe to be a blind spot: the state of water bankruptcy as a systemic and global condition being something bigger than the sum of the localized water issues mentioned in the introduction.
I don’t think water bankruptcy as defined above poses an existential threat to humanity. While it obviously combines with, reacts to, and amplifies some consequences of climate change, it is nonetheless an issue on its own, and I am not intending here to support the civilizational threat claim with climate change either.
Instead, my argument for the criticality of the threat lies on two components:
We can examine current consequences of water bankruptcy (which correspond to well-known issues) and ask:
Direct Impacts
Indirect cascading impacts
Can a combined catastrophe over these two domains lead to an economic collapse? Of what scale (global vs. regional)?
And a last one I am not too sure how to classify (didn’t seem that civilizational-threatening at first, but the number of densely inhabited areas made me think twice)
With all those current and potential future consequences in mind, I think that what makes water bankruptcy such a danger is its lock-in property. Without action at systemic level, irreversible damage to water systems may lock in permanent scarcity, preventing the global water system from returning to baseline and making future interventions far less effective.[1]
But this very need for systemic and global governance is where it gets tricky, according to me, and is why I think there is a high and neglected risk. First, the need for global action instead of an aggregate of local solutions currently faces the lack of global resource governance and treaties for water. This adds even more difficulty to the inherently lesser tractability of most systemic-level actions compared to operational interventions.
Now I just used the word “neglected risk”. Again, this claim is not toward water issues but on this framing of a potential civilizational risk. Is it truly neglected? I am not sure and happy to be shown it’s not. What I found is that while water receives attention from NGOs and governments, the global, systemic, mid-to-long-term, and irreversible aspects of water bankruptcy are inadequately addressed. The UN's Sustainable Development Goal (SDG) number 6 commits the world to sustainable water management, yet humanity is far from meeting it, so it doesn't change the structural picture (although I agree, lack of success to solve an issue does not necessarily mean this issue is neglected)
Within the EA community, now. On the EA forum I found no direct mention of "water bankruptcy." My review of the EA Forum is certainly incomplete, of course, and I am pretty sure I have overlooked some relevant content. Aside from our forum, I found that:
The UNU-INWEH 2026 report defines water bankruptcy as insolvency (overuse beyond renewable limits) plus irreversibility (permanent natural capital damage). It is not a temporary crisis but a persistent failure state. Key figures suggest massive scale (75% in water-insecure countries, 4 billion experiencing monthly scarcity, ~4% of land area subsiding).
In regard to its global scale and systemic cascading risks (economic collapse, conflict, climate feedbacks, mass displacement), I wonder if global water bankruptcy potentially qualifies as a civilizational risk.
It is to be one last time emphasized: this post presents a hypothesis, not a conclusion. I am uncertain and welcome discussion on:
If you work on water issues, know relevant orgs, or have thoughts on this analysis, I'd be grateful for feedback.
Hi, FelixG I really enjoyed this post!
I have a poor understanding of this topic. Most of all I wish I had a clear idea of what the biggest danger is from water mismanagement. I can't tell if it's pollution, aquifer drainage, mismatched timing, wrong location, or something else.
I once tried to take a look at existential risks from lost ecosystem services and wrote this brief summary against it qualifying as an existential risk (I know you specifically are NOT claiming existential risk, but I think the commentary is still useful grounding):
During my mini foray I was pretty shocked at how much water is being drained from aquifers. I wish I could spend some time thinking more deeply about the threats from water misuse.
As a general rule, I have found resource depletion threats tends to sound ominous, but turn out to be avoidable upon closer inspection. Resource depletion is usually hundreds of years out. And there are usually moderately more expensive alternatives which we would switch to, once we started to experience scarcity.
I would want to check on that for water bankruptcy: When would we run out. Where. Is this a new problem, or a fact of the environment. What viable solutions are there, if any.
I would like to see some specific examples of a water-crisis-cascade, to get an idea of how it has manifested so far.[1] Follow by some estimates of the maximum scale it could theoretically reach.
I just did a research report on vultures as an ecosystem service and got some high numbers of irreversible human health damage. So its very vivid to me right now that environmental damage can be huge, and far cheaper to avoid than to try to reverse. I could definitely see aquifer drainage as being a case of eating the seed corn and heading for worsening disasters. But I could also see it as having simple solutions and being hundreds of years away from becoming an issue, in most places.
(When I tried to do this for ecological collapse, I was shocked I couldn't find any real-world examples of cascading collapse. Which made me update that it's a much less likely source of unpredictable devastation.)
