the India water situation

I’m reading that a major city in India, Chennai, has run out of water. (This article is a couple weeks old – the situation might have changed since then, but they are on a knife edge regardless.) Chennai is India’s sixth largest city, with a population around 4 million. It is also a major business center. My employer for example has a large operation in Chennai, and it is not exactly what I would call a major multinational corporation. So if professional workers are being told to go home and get in line for drinking water rations, that sounds pretty serious.

I remember hearing about groundwater depletion in India for years, and it appears that has gotten to the point where if rainfall patterns are unexpected, there is no groundwater to fall back on as they have in the past. And if cities don’t have drinking water, what does that mean for industry and agriculture? This would seem to be bad news for the food supply. Sure, India can import food, but what happens when this occurs in other food-producing countries (like the U.S. Great Plains and major rice growers in Southeast Asia), and India is also competing with China and other populous countries in Asia and Africa for dwindling food stocks. Food is the nexus of land, water, and climate.

It is not just Chennai. According to the World Economic Forum,

As of 10 June, around 44% of the country was affected by various degrees of drought, due to a heatwave that has seen Delhi record its highest ever June temperature of 48℃. While south of the capital, the Rajasthan city of Churu saw highs of more than 50℃, making it one of the hottest places on Earth.

Around 600 million people are dealing with high-to-extreme water shortages, according to a 2018 report by NITI Aayog, a policy think tank for the Indian government…

By 2030, it’s predicted that 40% of the population will have no access to drinking water – and 21 cities, including Chennai and New Delhi, will run out of groundwater, impacting 100 million people, according to NITI Aayog.

Here are a few more eye-opening, if not jaw-dropping, quotes from Hong Kong-based Asia Times:

The southwest monsoons remain the biggest source of water in the subcontinent. The monsoons lead to a combination of water sources supporting human habitats that includes glaciers, surface irrigation and ground water. But redundancy and surplus have gone missing from this once abundant system. Taking their place are galloping shortages…

Mukherjee is one of the editors of a landmark study that was published earlier this year. It predicts a terrible loss of the glaciers that dot the Hindu Kush-Himalaya region. “The Hindu Kush Himalaya Assessment” says that even if urgent global action on climate change is able to limit global warning to 1.5 degrees centigrade, it will still lead to a loss of a third of the glaciers in the region by the year 2100…

This has major implications for India, China, Pakistan, Nepal and Bangladesh. While the nearly 250 million who live in the Hindu Kush-Himalaya region will be most impacted from the outset, another 1.65 billion people who depend on the glacier-fed rivers are primarily at risk.

So there you have it – India historically has been supplied by redundant water sources including glacier-fed rivers, groundwater, and seasonal rainfall. Two of those three seem to be in doubt, and that leaves them at the mercy of whether the monsoon happens as expected each year or not.

India is a major democracy with a lot of technical and agricultural know-how. If they are not solving these problems, it does not seem to me to bode well for the rest of the world.

It also occurs to me that reducing carbon emissions is not the solution to this urgent problem. At least, governments can’t put all their eggs in that basket. They will have to invest in major water conservation and water reuse initiatives, and possibly high-tech and energy intensive measures like desalination.

more news from the yeast vats

This article in Scientific American is about using fungus to generate everything from building materials to human organs to meat to substitutes to plastics.

Mycelium’s fast-growing fibers produce materials used for packaging, clothing, food and construction—everything from leather to plant-based steak to scaffolding for growing organs. Mycelium, when harnessed as a technology, helps replace plastics that are rapidly accumulating in the environment.

Mycelium also provides a cruelty-free way to create meatlike structures with a much smaller environmental footprint than traditional livestock, reducing greenhouse gas emissions, the use of food crops for feed and land use conversion. All these benefits come with little environmental cost: the process of growing mycelium results in limited waste (mostly compostable) and requires minimal energy consumption.

deliberate practice

Open Culture has a post with lots of links to ideas on the best ways to practice something new. Hint: just repeating bad habits doesn’t do the trick.

Psychologist Anders Ericsson, the single figure most closely associated with deliberate practice, draws a distinction with what he calls naive practice: “Naive practice is people who just play games,” and in so doing “just accumulate more experience.” But in deliberate practice, “you actually pinpoint something you want to change. And once you have that specific goal of changing it, you will now engage in a practice activity that has a purpose of changing that.”

So it turns out that experience and wisdom aren’t the same thing after all. I would say you can’t have wisdom without experience, but you can have experience without wisdom.

Universal Basic Income, VAT, and baby bonds

A few 2020 Presidential contender highlights:

  • Andrew Yang (polling at about 1%) is promoting a Universal Basic Income of $1000/month for all U.S. citizens 18 and older regardless of income. He would pay for it by scaling back some other assistance programs and instituting…a VAT.
  • Cory Booker (polling at about 2%) is promoting “baby bonds”, where every baby gets a $1000 bond annually, and low-income children get up to an additional $2000 per year.

These are all ideas that (any) Democratic President and Congress could explore together, if they were to get a chance and managed to keep the corporate lobbyists at bay. I am 1000% in favor of VAT. It is just one of those things that all other modern countries do and the U.S. does not. It works and we just need to do it. Other taxes people hate can be reduced.

Both the UBI and baby bond ideas are supposed to address inequality quickly. The baby bond idea is supposed to particularly help racial disparities in wealth very quickly, but there is no reason the UBI could not do that with some fine-tuning. I like the idea of setting kids up with assets in principal, but in practice I am afraid unscrupulous relatives, Wall Street and payday lenders will find a way to take advantage of them. The UBI would essentially just be a “Social Security for All” scheme. We have the bureaucracy for that all set up and ready to go, so it seems practical to me. The only other difference I see between the two is that the government can more easily go back on a promise to pay you in the future than it can take money away from you that it has already paid. But of course it can do either, let’s not be naive.

My verdict – I’d like to see a VAT and a carbon tax used to fund education, infrastructure, and research. All of these things should help keep people busy if technology really does lead to unemployment. People can study to upgrade their knowledge and skills, design and build infrastructure and other types of capital goods, or go into research and teaching. Unemployment and disability insurance could also be beefed up to cover the gaps.

hydrogen fuel cell buses

The transportation agency serving the University of Illinois Urbana-Champaign is using fuel cell-powered buses and planning to produce and store its own hydrogen supply.

The cost of acquiring the two new buses, a fueling station and fuel storage equipment will be about $3.5 million, of which $1.5 million will be covered by federal grants…

MTD plans to produce the hydrogen for its fuel-cell buses itself. It could use solar power, wind turbines or, if need be, gas from the local landfill to separate the hydrogen from oxygen in water molecules for the buses.
The transit agency will soon be accepting bids for the equipment it will use for that conversion. It plans to add a total of 12 hydrogen fuel-cell buses by 2023, or about one-tenth of its fleet. By that time, the rest of its buses will be diesel-electric hybrids.

I’ve always thought that nuclear power, fuel cells, and membranes for water treatment would go together pretty well for a coastal city. You could size the nuclear reactor for peak demand, then use the excess energy to desalinate and electrolyze sea water whenever you are not at peak demand, storing the hydrogen to use in transportation vehicles and any other applications where you need decentralized or off-the-grid energy. You can use the membrane technology to produce drinking water and water for industry, either from seawater or treated sewage. I think you could substitute LNG for the hydrogen in this system if you need to for some reason, for example if the nuclear reactor were down for maintenance. You would have that occasional pesky problem of nuclear waste to deal with, but I am gradually coming around to the idea that managing the risks of nuclear reactors and nuclear waste may be preferable to the certainty of destroying the planet’s ecosystems and oceans. Inventing fusion power would be nice.

heavy water

This article in TreeHugger suggests that one simple solution is not to ship so much water around as part of consumer products. It makes sense. Even if the water were added locally, say at the Amazon neighborhood distribution center, it could save a lot of weight and expense. Maybe local water utilities could get in on the game somehow, and at a minimum you would be using local water rather than transferring large amounts of water from one place to another without realizing it.

my campaign platform

I always fantasize in election years about what my campaign platform would be, in a fantasy world where I had political skills and was running. It’s not a useless fantasy, because it gives me a benchmark to measure candidates against when I’m thinking of who to vote for. So here goes:

  • Education – “free college” and trade school yes, but also universal preschool, lifelong education, and strong incentives for private sector skills training and retraining.
  • Infrastructure – I’ve talked a lot about this. Plan at the metropolitan area scale, take a broad view of infrastructure to include housing and green infrastructure. Include strong incentives for private sector capital investment.
  • Innovation – Flood universities with funding for basic research across the board. Make some bets on a few “moon shot” technologies like quantum computing, nanotechnology, fusion power, and advanced biotechnology. Include strong incentives for private sector R&D.
  • Corruption – also known as “campaign finance”, but that sounds boring. This is really about having voters rather than dollars decide elections, and having elected officials write laws that benefit a critical mass of citizens rather than a few large campaign donors. It’s really a prerequisite to achieving anything else in the long term. Hammer the fuckers relentlessly and voters might respond.
  • Nuclear Weapons – Sure I want world peace, but the public is incredibly cynical about that and this is a place to start. Remind people how horrifying and dangerous they are, and that we have way more than we could ever rationally need for any purpose. If we want others to give them up or stop pursuing them, we can easily lead by example. Just put them away as they wear out and don’t make new ones.

Maybe I’ll elaborate on these in future posts, if I get a chance.

Now, which politician do I think is the best match? I have a lot of research and paying attention to do. I think Bernie Sanders would be the strongest on campaign finance, and just making progress on that issue in an 8-year administration might be worth putting him in office. I also think he might be strong on peace. I think his instinct is to expand the welfare state without taking the first three steps to accelerate income growth over time. I’m not sure who I think would be strongest here. Possibly a rational, moderate Republican actually, if such an animal still exists. But I will never support any politician from that party as long as it continues to stand for bigotry, science denial, and war.

Amsterdam

Amsterdam is easily my favorite city that I have been to. The streets there are for people, and cars are just one of many ways to get around, and not the best way so not many people use them. They are not allowed to take up half the space in the city. There is public and political support for all this.

I used to think Philadelphia could be like Amsterdam. Of course, physically, it could anytime. Our enemies are ignorance and cynicism though, and I am less optimistic lately that these enemies can ever be overcome. The occasional visit to Amsterdam might be the best I can hope for, as long as it stays dry enough to visit (and if anybody can keep it dry, the Dutch will do that as long as it is possible. The Dutch are a bit smug, of course, but you have a right to be when you are pretty much doing everything right.)
