> The water level is so low that only one of the six turbines on Zambia's side of the dam is able to operate, cutting generation to less than 10% of normal output. Zambia relies on the dam for more than 80% of its national electricity supply, and the result is Zambians have barely a few hours of power a day at the best of times. Often, areas are going without electricity for days... The power crisis is a bigger blow to the economy and the battle against poverty than the lockdowns during the COVID-19 pandemic, said Zambia Association of Manufacturers president Ashu Sagar.

> Zambia is not alone in that hydroelectric power makes up over 80% of the energy mix in Mozambique, Malawi, Uganda, Ethiopia and Congo, even as experts warn it will become more unreliable. "Extreme weather patterns, including prolonged droughts, make it clear that overreliance on hydro is no longer sustainable," said Carlos Lopes, a professor at the Mandela School of Public Governance at the University of Cape Town in South Africa.
While the lake's water level normally rises six meters after it rains, "It moved by less than 30 centimeters after the last rainy season barely materialized, authorities said...
"Experts say there's also no guarantee those rains will come and it's dangerous to rely on [5]a changing climate given Zambia has had drought-induced power problems before, and the trend is they are getting worse."

The problem is not the climate, its planning (Score:3)
"Zambia relies on the dam for more than 80% of its national electricity supply"
There you have the problem. The planning did not take account the variability of the weather over a period of years or decades. They have produced intermittency, by trying to get more out of their hydro storage than was prudent.
If you are going to use intermittent sources of electricity, you have to be able to deliver supply through the periodic low points. Can be wind, with one or two week calms, can be solar, with overnight total outage, can be hydro, in which case you are limited by rainfall and its highs and lows.
It was fine to use hydro, it was even fine not to have anything else, as long as they kept within safe limits of their drawdown of the hydro. But demand is obviously too high for the system, so they are stuck with three choices:
-- install more hydro
-- install conventional, gas or coal
-- have blackouts
Their problems are due to climate, not climate change, and to having relied on weather dependent generation without planning for intermittency.

A climate that hasn't caused a problem to date and yet now has started to is a result of what? I'll give you a hint the word starts with "change" and ends with the dreadful realisation that you just wrote something monumentally silly.

Choice 4: Install solar. And maybe wind, but mainly lots of solar.
Solar is really cheap these days, but it's intermittent without storage. A hydroelectric dam that can't provide power constantly is a huge energy storage vessel. Solar works best in a sunny drought; hydro best when it's cloudy and rainy. They were made for each other!

Droughts in Africa are a thing, and stock-piling countless acres of water in a drought-prone region seems like a bad idea.
The issue isn't the drought/lack of rain, it's that Zambia chose to build a dam when they should have gone solar or wind to generate electricity. Water is a constant struggle in Africa, basingbtheir economic future on never having a drought again seems like a bad idea...

I'm talking about China, India, Pakistan, Bangladesh, large swaths of Africa, South-Eastern Asia. Also incidentally, the largest (by population) countries in these regions are also nuclear powers.

Population density isn't actually a relevant metric in the slightest. There are many metrics for judging how resilient a population is, but judging land is pointless. One needs to look at how the social structure is built around the population, and one of the best metrics for that is GDP since even looking after your own citizens without exporting anything is reflected in that figure.
For that you can compare the 20million people of Zambia with their $1,497 USD / capita GDP to the Netherlands 18.9 million pe
