“The Line” is Saudi Arabia’s bold vision for the future of civilization: an ultra-modern city designed to house 1 million people and be entirely pollution-free. ↠Subscribe: https://www.youtube.com/c/TerraMaterO…

But there’s one problem – it’s in the middle of the desert. And cities require a lot of water.

Enter the Solar Dome, a new desalination system built on existing technology. It’s supposed to be a low-cost, efficient, and carbon-neutral way of turning saltwater into fresh water. With water scarcity already threatening the Middle East, Saudi Arabia is the world leader in desalination, but the process does pose problems. We take a closer look at the environmental costs of desalination, and how new innovation like the Solar Dome is trying to tackle these issues.

Slaves, Spices, and Ivory in Zanzibar: Integration of an East African Commercial Empire into the World Economy, 1770-1873 (Eastern African Studies): Abdul Sheriff

The rise of Zanzibar was based on two major economic transformations. Firstly slaves became used for producing cloves and grains for export. Previously the slaves themselves were exported.

Secondly, there was an increased international demand for luxuries such as ivory. At the same time the price of imported manufactured gods was falling. Zanzibar took advantage of its strategic position to trade as far as the Great Lakes.

However this very economic success increasingly subordinated Zanzibar to Britain, with its anti-slavery crusade and its control over the Indian merchant class.

Professor Sheriff analyses the early stages of the underdevelopment of East Africa and provides a corrective to the dominance of political and diplomatic factors in the history of the area.

Review

“This long-awaited study by Abdul Sheriff adds significant richness in both its wealth of detail and meticulous analysis to our understanding of the rise of Omani Zanzibar and its changing place in the world economy. His prodigious archival research combines with his critical approach to Marxist theory to produce a convincing and stimulating interpretation of this critically important state during a major period of transition in the history of Eastern Africa.”—Professor Edward A. Alpers of the University of California, Los Angeles

In the 17th century, Oman drove out the Portuguese, who had occupied key coastal forts, and abandoning both their isolation and religious puritanism, became a commercial power in the Indian Ocean. Over the 18th century, through a combination of military and commercial means, not to mention propitious marriages, they came to control the East African coast from what is now southern Somalia, down to Mozambique.
Their rule, centered on the island of Zanzibar, was limited to a series of ports and forts, seldom extending far inland. The Omanis made a lot of money from the slave trade, exporting them to Arabia, India, and the burgeoning sugar islands of Mauritius and La Reunion. As a rising power in the region, Britain attempted to suppress the slave trade, not always from the purest motives.
When the export of Africans became difficult, the Omanis turned to clove plantations, using slave labor to work the crop. They also grew sugarcane and coconuts in Zanzibar and on Pemba, a neighboring island, and grain and oilseeds on the mainland. After a period of great profits, overproduction collapsed the clove business, plus the Omani slaveowning landords had become indebted to Indian moneylenders and customs agents. British power,looming ever larger, succeeded in separating Zanzibar from Oman, making two weaker kingdoms. But luckily for the Zanzibari ruling class, the rapidly industrializing West and its newly rich bourgeois craved exotic products.
At the same time, industrial goods were coming down in price, thanks to wider and higher rates of production. Ivory, culled from Africa’s then-magnificent herds of elephants, filled the gap left by the decline of clove growing. A vast trade network, dealing both in ivory and slaves, grew up covering a huge area from southern Sudan to the Caprivi Strip in Namibia and emerging from the roadless bush to a number of traditional ports on the east coast. Zanzibar traded in goods derived from the mainland (78% of exports came from there in the 1860s), and prevented other powers from dealing with the Africans directly. The British eventually suppressed the slave trade completely, ruining the country economically and forcing Zanzibar into protectorate status in 1890.
That is the story in brief. Dr. Sheriff has written a detailed history from the economic point of view, rather than from the more conventional direction of rulers, diplomats, treaties, and military moves. He studies classes, products, and means of production and does not offer any moral lectures on the evils of slavery. I would guess that it was a mighty job to gather all the material, especially since, as he notes in just one small place, he could not get access to the Zanzibar records.
This is reflected in the bibliographic notes, where he lists the archives he consulted-in the UK, USA, France, and India. The book abounds with maps, charts, diagrams, old lithographs and photographs (though his chapter on the hinterlands is full of place names that do not appear on any map !—not an easy haul for non-specialists.) As I live less than two miles from Salem, Mass. I was very interested to see the major role that traders from there had played in Zanzibar history. The American consul was long an important figure in Zanzibar and during the American Civil War, the Zanzibari economy took a nose dive. These are all aspects of my own local history that I was completely unaware of.In short, this is a fascinating history of a little-known part of the world which shows how it was inexorably tied in to the global capitalist network. It is not for general readers, but must be considered a major work for specialists, students of African history, and those interested in economic history. I am glad I ran across it.

The New McCarthyism: Congress Grills Columbia Univ. President Amid Crackdown on Pro-Palestine Speech

Democracy Now! Apr 18, 2024 Latest Shows

Support our work: https://www.democracynow.org/donate?c…
In nearly four hours of grueling congressional testimony before the Republican-led Committee on Education and the Workforce, the president of Columbia University, Nemat “Minouche” Shafik, said she had taken serious action against accusations of antisemitism on campus in recent months amid Israel’s assault on Gaza, including dismissing or removing five faculty members from the classroom, suspending 15 students and suspending two student groups — Students for Justice in Palestine and Jewish Voice for Peace. Shafik’s visit to Capitol Hill is the latest in a series of hearings on alleged antisemitism at elite U.S. private schools.

In December, similar hearings led to the resignations of the presidents of Harvard University and the University of Pennsylvania. Our guests Nara Milanich and Rebecca Jordan-Young, both professors at Barnard College and Columbia University, respond to the televised hearings. “What happened at those hearings yesterday should be of grave concern to everybody,” warns Jordan-Young. “What we got was a live performance [of President Shafik] throwing the entire university system under the bus.” Adds Milanich, “Antisemitism here is being used as a wedge. It’s being used as a Trojan horse for a very different political agenda.”

Why Bill Gates Is Buying Up U.S. Farmland

CNBC Aug 21, 2021
#CNBC

Bill Gates made headlines for becoming the largest private farmland owner in the U.S. But he’s not the only one. Some of the wealthiest landowners including Jeff Bezos, John Malone and Thomas Peterffy are buying up forests, ranches and farmlands across the United States. Why? Watch the video to find out.

Investments in farmland are growing across the country as people, including the ultra-wealthy like Bill Gates, look for new ways to grow their money.

In 2020, Gates made headlines for becoming the largest private farmland owner in the U.S. He had accumulated more than 269,000 acres of farmland across 18 states in less than a decade. His farmland grows onions, carrots and even the potatoes that are used to make McDonald’s French fries.

“It’s an asset with increasing value,” American Farmland Trust CEO John Piotti said. “It has great intrinsic value and beyond that, it is a limited resource.”

The U.S. Department of Agriculture estimates that 30% of all farmland is owned by landlords who don’t farm themselves. Buyers often purchase land from farmers who have owned it for decades; many of whom may be asset rich but maybe cash poor.

“The economic realities for them are typical that they’ve spent their life farming,” said Holly Rippon-Butler, land campaign director at the National Young Farmers Coalition. “Their retirement, their equity is all in the land and tied up in selling land.”

Private landowners are also making a profit by utilizing the land in numerous ways. Approximately 39% of the 911 million acres of farmland across the U.S. is rented out to farmers, and 80% of that rented farmland is owned by landlords who don’t farm themselves data from the Agriculture Department shows.

“The young farmers are just as happy to lease the land because whether you are young or old, it’s a business, right?” said Thomas Petterfy, chairman of Interactive Brokers and owner of 581,000 acres.

“You go buy a farm and you put that cash rental lease in place, you’re going to be looking at about 2.5% return on your capital,” Peoples Company President Steve Bruere said.
