#Africa: #LithiumMining in Africa Reveals Dark Side of #GreenEnergy
By Kate Hairsine
Deutsche Welle (Bonn)
16 November 2023
“The new rush for lithium in Africa risks fueling #corruption and harming local communities and the #environment, investigations have shown.
“At a Chinese-run lithium mine in #Namibia, local workers have complained for months about squalid living conditions and #unsafe work practices.
“An August fact-finding mission by the Mineworkers Union of Namibia into the Uis mine -- which is operated by Chinese mining company #XinfengInvestments -- found the the local miners living in tiny and hot corrugated zinc shacks without proper ventilation.
“The union also faulted a lack of privacy in the sanitation blocks where toilets and showers are lined up without partitions between them.
“In contrast, the Chinese workers at the mine have comfortable air-conditioned rooms and decent bathrooms.
“The union also criticized Xinfeng for failing to provide protective clothing and ensure safety measures for local workers.
“This is not the only controversy surrounding Xinfeng Investments. A new investigation into lithium mining in Africa by UK-based nonprofit #GlobalWitness outlines accusations against the firm ranging from acquiring the #Uis industrial mine through #bribery to developing it using permits intended for artisanal miners.
“Developing the mine with small-scale licenses meant the company paid 'a staggering low amount for access' to the lithium deposit and allowed it to skirt some #EnvironmentalRegulations, the investigation says.
Concerning trend of #corruption
“As well as in Namibia, the report also documents human rights abuses, corruption, displacement and unsafe working practices in lithium mines the Democratic Republic of the #Congo and #Zimbabwe.
“Going back decades, the mining sector in Africa has often involved corruption and communities not really getting a share of the profits,' said Global Witness senior investigator Colin Robertson, one of the report's authors. 'What we found in the lithium sector is that this trend is set to continue. ... This is very concerning.'
Race for lithium
“Called the 'white gold' of the renewable energy revolution, lithium is a key component of the rechargeable lithium-ion batteries that power everything from cell phones to electric cars (#EVs). Such #batteries are also vital for storing energy produced by clean energy like solar or wind if the world is to make the break from #FossilFuels.
“Globally, the lithium supply is currently dominated by #Australia, #Chile and China, who together produced 90% of the light metal in 2022. But with about 5% of the world's lithium ore reserves, Africa still holds enormous potential, most of which is untapped. Currently only Zimbabwe and Namibia have exported lithium ore, while projects in nations such as #Congo, #Mali, #Ghana, #Nigeria, #Rwanda and #Ethiopia are under exploration or development.
“With demand for the critical mineral expected to boom -- it could grow 40-fold by 2040, according to International Energy Agency projections -- major economies and international companies are racing to secure access to lithium on the continent.
“And many African nations are embracing the lithium rush.
Mineral of the future
“'Lithium is the mineral of the present and the future,' Zimbabwe's president #Emmerson Mnangagwa said recently.
“Zimbabwe, which has Africa's largest lithium reserves and is ranked sixth globally for lithium exports, earned $209 million (€193) from the mineral in the first nine months of 2023. That's nearly treble last year's earnings.
“The southern African country, along with Namibia and Tanzania, has banned the export of raw, or unprocessed lithium, as it seeks to get added value from the lightweight metal.
“Zimbabwe's ban is far from watertight. Global Witness' research discovered that large amounts of lithium ore are still being trucked out of the country.
“In addition, Zimbabwe Defence Industries, a military-linked company subject to US and EU sanctions, has been granted a special exemption to export lithium ore to China. The director of the Harare-based Centre for Natural Resource Governance, Farai Maguwu, is appalled by this.
“'Even though they don't own a single lithium mine,' he told DW, 'they were given an export permit.'
Lithium is a curse
“Maguwu is pessimistic when asked if lithium mining brings any benefit to Zimbabwe.
“’Not at all,' he answered. 'If anything, this abundance of lithium deposits in the current system of governance is actually a curse to the country.'
“If anything, it will bring the country down because there are no systems in place to ensure that the country can generate revenue for the benefits, first and foremost, of the host communities which must pay the cost of mine, loss of land, loss of #biodiversity and the social intrusion into their space.'
“He gives the example of the #SandawanaMine where a lithium rush saw thousands of locals digging out lithium. In early 2023 though, the mine was reportedly taken over by companies with links to Zimbabwe's ruling ZANU-PF party and military.
“'Even where the local people are able to mine and sell legally, the government sent troops armed to the teeth to stop people from accessing the lithium,' Maguwu said.
“There is 'no silver bullet' to the problem of corruption in Africa's mining sector, he said, but he would like to see more Western mining companies invest in extracting Africa's lithium, as they are often bound by stricter environmental, social and governance standards and practices.
Fear of Chinese monopoly
“China has a virtual monopoly on lithium extraction in Africa. More than four-fifths, or 83%, of Africa's forecast lithium supply this decade will come from projects at least partly owned by Chinese firms, estimates Benchmark Mineral Intelligence, a consultancy.
“Three Chinese mining giants have acquired lithium mines and projects worth $678 million in Zimbabwe in the past year.
“'Domination [of lithium mining] by one country may led to undesirable results such as under-valuation of mineral resources, #TaxAvoidance and #HumanRights abuses in the sector,' according to a recent report by the Zimbabwe Environmental Law Association.
“The Global Witness researcher Robertson calls on the European Union and the United States to ensure increased transparency of lithium mining and more oversight by local activists in order to improve governance and combat corruption.
“'It can't just be about [the EU and US] trying to increase their own supply of minerals,' he said.
“As for Farai Maguwu, he stresses that the proceeds from extractive projects must be plowed back into the community in terms of public goods, such as roads, health clinics and schools.
“’We consider our unmined assets as our natural capital and the local people, even children, should enjoy the benefits of the extraction of their natural capital.’”

It's just crazy for me how obsessed Zuckerberg has become.
Many companies have obsessed about technologies in the past.
#Microsoft was obsessed with touchscreen-friendly #UIs when #Windows8 came out as well as the #WindowsMobile operating system. They were able to realise that people didn't like it, so they moved on. Where #Nokia got obsessed with the #WindowsMobile idea and never moved to #Android, resulting in their death.
#Blackberry was the first company to release a "smartphone" at that time. They knew people wanted to email and communicate more efficiently on their phones, and phones were no longer just for calling. So they released the full qwerty-keyboard. But they got stuck with it and didn't realise the strengths and flexibility of touchscreen-keyboards and the screen real estate that you lose with hardware keyboards. So their phones died out.
A map of the 1860 US presidential election results from The Sangamon Experience at #UIS. Mirroring today's political situation, Abraham Lincoln won in his city of Springfield, lost Sangamon County which contained it, but won Illinois itself. The split in Illinois largely goes along lines of settlement waves: Southerners entering by crossing Kentucky and the Ohio River, and Northerners coming by way of the Erie Canal and the Great Lakes.
There was a #solar #telescope at the #UIS #Observatory but the weather didn't cooperate :(
The news I thought was neat:
The #UIS Observatory participates in the #GlobalMeteorNetwork (https://globalmeteornetwork.org/), running two nodes in "a #decentralized #science-grade instrument which observes the night sky every night of the year from as many locations around the world as possible."
During last week's #Geminid showers, 85 meteors were observed on campus, and 182 were seen at the off-campus #astronomy #research #observatory.
Neat visualization of the data too! #dataviz

@kidkreole I'm game for that. I'm going to reply so they're at least linked. It's kind of cheating since I don't have anything tagged in my profile.
