Climate change endangers Mauritania’s centuries-old date harvest | The Express Tribune

Published

MAURITANIA:

Wandering atop a small sand dune in central Mauritania, Aliene Haimoud gazed despondently at the yellowing date palms before him –- the trees are dying if they are not already dead.

The advance of the desert is striking in the oasis village of Azougui, some 450 kilometers (280 miles) northeast of Nouakchott, the West African state’s capital.

Despite the ever-encroaching sand which is gradually swallowing up the trees, residents here are preparing for the Guetna -– the annual harvest date.

The popular event is rooted in a long nomadic tradition and involves large family celebrations centered around the small, sweet fruit—the region’s main source of income.

“You go from 10 to 1,000 friends,” one local said cheerfully.

But when a palm tree dies, a little of the life in each village is extinguished.

“Because of the sand, people are forced to settle elsewhere, because here there can be no more harvests,” said Haimoud, president of the local cooperative association.

Nearly 20,000 palm trees have perished since the 1980s and his village is becoming emptier every year, he said.

Like other countries in Western Africa and the Sahel region, Mauritania is on the front lines of climate change.

Temperatures in the region are rising 1.5 times faster than the global average, while rainfall is erratic and wet seasons are decreasing, according to a 2022 report from the UN Human Rights Office.

Massive flooding in M’Heiret two years ago devastated the village’s palm trees.

In Mauritania, the government has tried to halt the desertification by planting trees to repel the onslaught of sand.

But the chosen prosopis variety has caused the soil to dry out even more, further exacerbating the palm trees’ fragility.

Around 70 kilometers further south, the green oasis of M’Heiret has also been decimated.

Some 6,000 palm trees, already weakened by years of drought, were swept away two years ago by the massive flooding of a wadi—a stream that forms during the rainy season.

The trees now lie in the riverbed, which is completely dry at this time of year.

“This place used to be full of palm trees,” said Amou Dehah, who was mayor of the village at the time.

“Their owners are still here, but there’s nothing left for them,” he added.

‘Only source of income’

“If there are no more palm trees, there is no more work. If there’s no work, there’s no money,” Dehah said.

Mohamed Mahmoud Ould Brihm is concerned for his crop of 50 palm trees which have been passed down through generations.

“We need to find a solution. If we don’t, people will go and live elsewhere, because this is our only source of income,” he added.

Beside him, 56-year-old Mohamed Mahmoud Ould Brihm said he was worried about his 50 palm trees which are planted close to the wadi and have been passed down through generations.

“Of course, I’m afraid of losing everything. I’m even afraid that my house will be destroyed,” he said.

The residents of M’Heiret, which is renowned for its quality and variety of dates, have called for the construction of a dam which they say would act as a buffer against future downpours and create favorable growing conditions.

“The dam is the best solution,” said Houdy Sidina, professor of biology and agronomy at the University of Nouakchott.

“It helps to combat drought, irrigate palm trees and prevent flooding,” he added.

Sidina referred to the region’s Seguelil Dam, which was inaugurated in 2019, and permanently irrigates the surrounding oasis, transforming the lives of local people.

The government has also improved irrigation systems, provided solar panels and planted new date palms for poor farmers, said Sidi Ahmed, president of a network of groups for the sustainable development of oases.

In his garden of around 20 palm trees near the regional hub of Atar, Moustapha Chibany picked a succulent date and popped it in his mouth.

“What interests me is not the economic aspect, it’s the love of dates. Without them, there would be no life here, in such hostile conditions”, he said.

Faced with competition from North African dates, Chibany said that sharing the most effective techniques, combating waste and promoting better quality species, would help revive the Mauritanian industry.

SpaceX achieves unprecedented feat in commercial space travel | The Express Tribune

Published

on

By



WASHINGTON:

Two astronauts, a billionaire and an engineer, completed the first private spacewalk in orbit on Thursday outside a SpaceX capsule. They wore a new type of spacesuit in a high-risk feat once limited to astronauts from government space agencies.

As part of the Polaris Dawn mission, the astronauts each spent about 10 minutes outside the Crew Dragon capsule, tethered for safety, while their two crewmates remained inside. The mission, led by Elon Musk’s SpaceX, further pushed the boundaries of private space travel.

Jared Isaacman, a pilot and founder of Shift4, was the first to exit, followed by SpaceX engineer Sarah Gillis. Meanwhile, their crewmates Scott Poteet and Anna Menon observed from inside the capsule. Orbiting about 450 miles (730 km) above Earth, the entire spacewalk lasted one hour and 46 minutes.

Isaacman, who also funded the Polaris mission, previously financed his Inspiration4 flight with SpaceX in 2021. The mission, streamed live on SpaceX’s website, tested new equipment, including slimmer spacesuits and a procedure to fully depressurise the Crew Dragon cabin – technology that Musk aims to refine for future private missions to Mars.

After re-entering the spacecraft, Isaacman commented on Earth’s beauty, as seen from space. This mission was one of the riskiest for SpaceX, the only private company capable of regularly sending people into orbit and back.

Before the spacewalk at around 10:52 GMT, the capsule was completely depressurised, with the astronauts relying on their SpaceX-designed spacesuits for oxygen via an umbilical connection to the capsule. Isaacman, 41, and Gillis, 30, tested the suits’ flexibility and provided feedback to improve future designs.

The mission aimed to push the limits of private companies in space, with ground teams at SpaceX’s California headquarters monitoring the hatch’s closure and carrying out safety checks as the astronauts returned inside.

The spacewalk procedure echoed that of the first US spacewalk in 1965, which involved depressurising the capsule and tethering a spacesuited astronaut to it. NASA Administrator Bill Nelson hailed the mission as a “giant leap forward” for the commercial space industry and NASA’s goal of building a sustainable US space economy.

While Isaacman has not revealed the mission’s cost, it is expected to run into hundreds of millions, with Crew Dragon seats typically costing around $55 million each.

Gillis, who joined SpaceX as an intern in 2015, and Poteet, a retired US Air Force lieutenant colonel, were among the crew, along with SpaceX engineer Anna Menon. Throughout the mission, the spacecraft circled Earth multiple times, reaching altitudes of up to 1,400 km, the farthest humans have travelled in space since Apollo’s final mission in 1972.

Spacewalks have previously been conducted solely by government-trained astronauts. Since the International Space Station (ISS) was established in 2000, there have been around 270 spacewalks, with 16 on China’s Tiangong space station.

The Polaris crew spent two and a half years training, including mission simulations and challenging real-world experiences, to prepare for the mission, according to Poteet.

Currently, a record 19 astronauts are in orbit, including 12 aboard the ISS, after a Russian Soyuz mission transported additional astronauts there on Wednesday. Since 2001, Crew Dragon has completed more than a dozen astronaut missions, primarily for NASA.

The capsule was developed under a NASA programme to create commercial vehicles for transporting astronauts to and from the ISS. Boeing’s Starliner capsule, also part of this programme, launched its first astronauts to the ISS in June but faced difficulties. It returned empty, leaving its crew aboard the station until next year, when a Crew Dragon capsule will retrieve them.

The demand for the PS5 Disc Drive has skyrocketed since the announcement of the PS5 Pro, with online retailers quickly selling out of the popular peripheral.

Gamers eager to ensure they can still play physical media on their next-gen consoles are rushing to purchase the external disc drive required for the new PS5 Pro.

Sony officially revealed the PS5 Pro earlier this week, and with it came the announcement that the console would not include a built-in disc drive.

Instead, players who want to use physical discs will need to buy the external PS5 Disc Drive, a shift that has already sparked a buying frenzy.

At the time of writing, the PS5 Disc Drive has climbed to #16 on Amazon’s best-selling video game products.

Best Buy, one of the major online retailers, has already sold out of the drive, and it is currently unavailable for order. Gamers are still able to find it on other major sites like Target, Walmart, and PlayStation Direct, but these supplies are expected to diminish quickly as well.

This rush to secure the PS5 Disc Drive began when Sony introduced the PS5 Slim in late 2023, which also required an external drive for physical game compatibility. Unlike the original PS5, which featured both disc and digital editions, the Slim removed the option of having a built-in disc drive.

US wireless data usage surges to record 100 trillion MB in 2023 | The Express Tribune

Published

Americans consumed more than 100 trillion megabytes of wireless data in 2023, a 36% rise from the previous year and the largest single-year increase, according to a report from wireless industry association CTIA.

The surge in usage—an increase of 26 trillion MB over 2022—is attributed to the growing adoption of 5G devices and fixed wireless access (FWA) broadband services.

The total number of wireless connections in the US rose to 558 million, representing a 6% growth over 2022. Notably, 40% of wireless connections were 5G-enabled, covering over 330 million US residents.

Additionally, nearly 40% of all wireless devices were connected to 5G, a 34% increase from 2022.

CTIA highlighted that the sector attracted $30 billion in investment in 2023, with total spending on spectrum auctions surpassing $233 billion.

However, the association emphasized the need for Congress to restore the Federal Communications Commission’s (FCC) auction authority to ensure access to mid-band spectrum and meet the growing demand for wireless services.

By the end of 2023, the US had 432,469 active cell sites, a 24% increase since 2018, thanks to siting reforms.

The cost per megabyte of wireless data has dropped by 50% since 2020.

CTIA’s annual survey has tracked the US wireless sector since 1985.

Listen to article

Black Sun Productions, a virtual reality studio, has announced its debut title, Metamorphosis VR, will launch on October 10, 2024.

The narrative inspired by Franz Kafka’s The Metamorphosis will be available for Meta Quest 2 and 3.

This VR game offers a unique and immersive experience, allowing players to step into the surreal world of Kafka’s renowned novella.

Metamorphosis VR is a bold reimagining of the 2020 PC game Metamorphosis, originally developed by Ovid Works and Untold Tales.

The story takes place in early 1900s Vienna, following Gregor Samsa, a traveling salesman who undergoes a shocking transformation into a cockroach.

After a night out, Gregor awakens to discover his metamorphosis and embarks on a strange journey to find a way to return to his human form and save his closest friend.

“We chose Metamorphosis as our debut title for Black Sun because its surreal, Kafkaesque world – some of the richest and most immersive environments imagined – offers a perfect opportunity to bring this extraordinary experience to virtual reality,” said Corbin Chase, CEO of Black Sun Productions, in a statement, as reported by VentureBeat.

“One of VR’s most powerful abilities is how it changes our perspective and sense of scale, and Metamorphosis uniquely combines confusion, bewilderment, wonder and beauty. All imparted by that shift in perspective, it feels like this game was always meant for VR.”

One of the game’s key highlights is its distinct shift in perspective, which allows players to experience Gregor’s new reality as an insect.

Navigating through walls, floorboards, and tight spaces, the player is immersed in a bizarre world filled with bug philosophers, insect crime bosses, and creepy thespians.

The game features over 100 insect characters, each with a unique voice, contributing to an interactive experience.

Fans of Kafka’s original novella and virtual reality enthusiasts eager to explore its surreal world are anticipating the game’s October 10 release on Meta Quest 2 and 3.
