Although the water sector really needs more and better information (that's why I founded the water data hub*), I worry about people putting the wrong weight on the wrong information -- a worry that puts these recent stories into a different context:
- The World Resources Institute released the Aqueduct 2.0 tool for water risk.
- IBM and Waterfund (a global water risk management firm) created a benchmark with which to assess risk when it comes to investing in the water sector.
- Ceres has put out another report on the importance of water risk to companies.
What I worry about is the arrival of over-simplified models of risk and tools for "managing" risk, and the damage that may result from the naive application or use of these models.
I worry, for example, of what might happen if:
- Some 25 year-old bets your pension based on "data" from his Bloomberg terminal (Bloomberg partners with WRI).
- Banks or governments allocate investments based on the IBM-model of risk.
- Investors move their money based on Ceres' risk warnings.
I'd put a lot more weight on:
- Local institutions for managing water. They determine the difference between drought and shortage.
- Political and regulatory interventions (i.e., "regulatory risk") that outweigh natural risk by an order of magnitude.
- The importance of funding local water projects with local money -- especially when it comes to knowing the people who are spending your money.
Each of these factors, IMO, are significant, and each can overwhelm any number that you get from a risk model.
Bottom Line: Caveat emptor! Risk in the water world is not so much about nature or market forces, but the arbitrary, illogical, unaccountable and uncertain ideas and actions of politicians and bureaucrats who drive water management (and cause 90 percent of the mismanagement).
* The WDH does not worry me because it's merely a way of finding data (is yours linked?). People can then interpret the data any way they want.

Good point, David. Makinging an open database that is both popular and reliable would be best.
ReplyDeleteThanks for posting this; this is a relevant trend that is likely going to control the water debates for a while. At the moment there are more organizations working on water risk tools like these, and from my perspective they seem to be in competition over access to funds, media exposure etcetera.
ReplyDeleteIt is much like the "water footprint" discussion or even the "water stewardship" approach. Over the years, I have been in contact with several of the people behind these ideas; though they do have good intentions and some good ideas, in general they do not acknowledge the full complexity of water issues, or the weaknesses of presenting their tools and interpretation as a final risk assessment.
I have recently started on the idea (WaterLeaks) to create a transparent website that collects all these different water approaches and let people write critical reviews on their experiences and suggestions (e.g. tripadvisor-style). Map out the organizations and sponsors behind the tools, and probably allow people to add case studies. On current capacity, it would take months before anything public and interactive comes out. As far as I know, such a transparent meta-level on water tools is not out there yet... anyone please let me know if it already is, would save me a lot of work.
@Niksin -- Agreed. I've a plan to have such "comments on quality" on the water data hub in the future...
ReplyDeleteIt seems, everyone likes to join the water risk bandwagon. Have to admit, I was one of them when I developed XXX and currently expanding the same by bringing in energy and agriculture components to it.
ReplyDeleteI feel, any model which tells the story using global data would almost always make hollow claims with reference to (i) time, and (ii) resolution. Most of global water data (e.g. risk, demand, supply) currently used are circa 2000. Secondly, water being a local issue one needs local (higher resolution) data. For example, even if one has storage capacity of dams, when and how much water is released is equally important for demand/supply and risks aspects.
I think waterfund, Bloomberg (has tied up with SIWI to develop yet another index, not sure if they’ve still continued their association with WRI!) are simply trying to define rules of the game especially among investor community; once done they can provide manuals. But I think, they still have a long way to go. We’ll see!
The trouble is there are too many non-water issues responsible for the current state of water. Energy availability is a case in point. For me water is the most assuredly renewable resource on the earth. Energy is not. If energy and materials are not limiting factors, I can desalinate Indian Ocean and pump it to Mount Everest. In Africa, for example, if one resolves access to energy issue, there is plenty of groundwater, one can easily solve drinking water problem. So to solve water problem at least n Africa, one needs to invest in energy first. The vicious circle for water in fact starts there.
I liked this post, and I agree that there are clear dangers in having (mostly opaque) metrics that result in the movement of huge sums of money.
ReplyDeleteIncidentally, one thing that continues to bother me is that most of these risk models--Aquaduct included--ultimately rely on the (largely arbitrary) categories of water stress that were outlined by the United Nation's Comprehensive Assessment of the Freshwater Resources of the World (1997).
In this report, watersheds with demand/supply ratios ("criticality" ratios) of >0.4 are said to be experiencing medium-high water stress. 0.4 is the magic cut-off that always seems to appear at the end of the chain of citations. It's eerie!
