A drone buzzed back and forth above rows of verdant orange trees planted near Nabeul, eastern Tunisia.

The black unmanned aircraft, equipped with a multi-lens camera and sensors, has been enlisted by Tunisian farmers to help adapt to years of drought and erratic weather patterns caused by climate change.

“The seasons are not like they were before where we knew exactly what to do,” said farmer Yassine Gargouri, noting temperatures now can begin to climb as early as May while in August there have been unusual summer rains.

He hired start-up RoboCare to scan the trees from the air and assess their hydration levels, soil quality and overall health — to prevent irreversible damage.

The technology “provides us with information on how much water each plant needs, no more, no less,” he said.

The use of modern technologies in agriculture is globally on the rise, including in North Africa where countries rank among the world’s 33 most water-stressed, according to the World Resources Institute.

RoboCare, employing about 10 people, is the only company in Tunisia, according to its 35-year-old founder Imen Hbiri, to use drones to help farmers combat the impacts of climate change and reduce costs, crop losses and water consumption.

“Resorting to modern technologies in the sector of agriculture has become inevitable,” Hbiri told AFP while monitoring the drone’s path on her computer screen.

‘Challenge of tomorrow’

The daughter of farmers, the entrepreneur knows well the limits of existing farming methods.

Now, in just a few clicks, she can access scans that detect signs of illness or malnourishment before they are visible to the naked eye.

On the screen, fields appear in RGB (red, green, blue) imagery — the greener the plants, the healthier.

Farmers can then use medicine-filled sprinklers mounted to the drones to target the sickly plants with more precision and consequently less expense.

“By relying on this technology, we can save water consumption by up to 30 percent and reduce about 20 percent of the cost of fertilizers and medicine, while raising crop production by 30 percent,” Hbiri explained.

Gargouri, who spends about 80 percent of his budget on fertilizers and other remedies, says this technology is the future.

“We must adapt to these upheavals,” Gargouri added. “It’s the challenge of tomorrow.”

Tunisia is currently experiencing its eighth year of drought (four of which were consecutive) in recent years, according to its agriculture ministry.

The country’s dams, which are the primary source for drinking water and irrigating crops, are currently only filled to about 22 percent capacity.

And about 20 dams — mostly located in the south — have gone completely out of service.

In neighboring countries, water scarcity is also a major issue.

Licensing hurdles

Morocco — where agriculture accounts for 13 percent of the gross domestic product, 14 percent of exports and 33 percent of jobs — also suffered its worst drought in four decades in 2022.

Only about three percent of nearly two million Moroccan farmers use new technologies in their fields, Loubna El Mansouri, director of the digital center at Morocco’s agriculture ministry, told AFP.

A study they conducted found that using drones to water crops could use “less than 20 liters of water to irrigate one hectare compared to nearly 300 liters” used with traditional methods, Mansouri added.

Similarly, Algeria’s agriculture ministry said it was using drones and satellite imagery for mapping “to optimize the use of agricultural land by evaluating its characteristics and suitability for production”, local media reported.

For the use of these technologies to become widespread, however, Hbiri says the law needs to be changed in Tunisia and awareness raised.

Algeria, Morocco, and Tunisia ban the use of unmanned drones without a permit, which in the case of commercial uses can take months to be issued.

Hbiri hopes authorities will help start-ups reach more farmers as she estimates “only 10 percent of farmers in Tunisia depend on this type of technology.”

“We want to focus our work on the use of technology and not spend time and effort on administrative issues and moving between departments and banks, which is slowing our progress,” she said.

Michael Genaldi’s road to homelessness began early this year when a car slammed into the rear of his motorcycle, crushed three of his ribs, and left him in a coma for over a month.

The 58-year-old lost his job as a machine operator, then his home, and he was living in his truck when he was diagnosed with stage 2 lung cancer. Too young to get Social Security, Genaldi now lives temporarily in a shelter for people 55 and older in Phoenix while he navigates the process of qualifying for disability payments.

As its population ages, the United States is ill-prepared to adequately house and care for the growing number of older people, concludes a new report being released Thursday by Harvard University’s Joint Center for Housing Studies.

Without enough government help, “many older adults will have to forgo needed care or rely on family and friends for assistance,” warned Jennifer Molinsky, project director of the center’s Housing an Aging Society Program. Many, like Genaldi, will become homeless.

Molinsky said more governmental assistance could better help the upsurge of older Americans who are baby boomers born after World War II.

The report says that in 2021, federal housing assistance like Section 8 or Section 202 — which provides housing with supportive services such as cleaning, cooking and transportation for older people — was only sufficient for a little more than a third of the 5.9 million renters ages 62 and over who were eligible.

Creative ideas are especially needed now to house people with fixed or dwindling incomes and with insufficient savings, the report says. Think house or apartment sharing to cut back on costs rather than living alone, in accessory dwelling units or ADUs known as casitas, granny flats and in-law units. There are also cohousing communities where individual homes — sometimes even tiny homes — are arranged around a building with a communal space such as a dining room.

Over the next decade, the U.S. population over the age of 75 will increase by 45%, growing from 17 million to nearly 25 million. And many of those people are expected to struggle financially. The report notes that in 2021, nearly 11.2 million older adults were “cost burdened,” which means they spend more than 30% of their income on housing.

Some of the highest cost-burden rates for renters 65 and older were in Sunbelt areas traditionally popular for retirement: Las Vegas; San Diego; Raleigh, North Carolina; Miami and Daytona Beach, Florida.

Like renters, many older homeowners also struggle to keep a roof over their head.

The report says that mortgage debt among older adults is rising, with the median mortgage debt for homeowners 65 to 79 shooting up over 400% from $21,000 in 1989 to $110,000 in 2022 as people increasingly need to access cash for basic needs and care.

Many older adults also find it challenging to obtain the additional services they need as they age, with the costs of long-term care averaging over $100 a day.

The report says the households of older people of color are far more likely to be cost burdened than older white households, especially Black and Latino households. Older people who live alone are also more likely to be cost burdened than married or partnered couples: 47% versus 21% of couples.

In Phoenix, Angelita Saldaña, 56, became homeless after her marriage fell apart. The granddaughter of Mexican immigrants, Saldaña initially lived in her truck with her pet dog Gaspar, but they now live at the 60-bed shelter where Genaldi stays with his pet dog Chico.

Saldaña said her $941 monthly disability check isn’t enough to pay for even a studio apartment in the area, where average rents start at around $1,200. A caseworker is trying to help her find something she can afford.

In the meantime, she has a motel room to herself with a private bathroom.

“Here, I can sleep good,” she said, unlike the months she spent at the state’s largest shelter in downtown Phoenix, which has 10 times as many beds.

Lisa Glow, the CEO for Central Arizona Shelter Services, which operates both facilities, said older people do much better in a shelter designed with their needs in mind — including more space, limited stairs and wider doorways for wheelchairs.

Glow spoke of an 82-year-old man with dementia who struggled to sleep on a bunk bed at the downtown shelter before he was transferred. Staff members tracked down his family and got him transferred to a skilled nursing facility for more personalized care.

“The downtown shelter is not a good place for an aging adult with chronic conditions,” said Glow. “We see a lot of people there in their 70s and 80s.”

“I’ve been shocked to see so many seniors on the street,” she added. “People with wheelchairs. People with walkers.”

Flu is picking up steam while RSV lung infections that can hit kids and older people hard may be peaking, U.S. health officials said Friday.

COVID-19, though, continues to cause the most hospitalizations and deaths among respiratory illnesses — about 15,000 hospitalizations and about 1,000 deaths every week, said Dr. Mandy Cohen, head of the Centers for Disease Control and Prevention.

The agency is also looking into reports of pneumonia outbreaks in children in two states, but Cohen said “there is no evidence” that they are due to anything unusual.

As for the flu season, seven states were reporting high levels of flu-like illnesses in early November. In a new CDC report Friday, the agency said the tally was up to 11 states — mostly in the South and Southwest.

In the last month, RSV infections rose sharply in some parts of the country, nearly filling hospital emergency departments in Georgia, Texas and some other states. But “we think we’re near the peak of RSV season or will be in the next week or so,” Cohen said.

RSV, or respiratory syncytial virus is a common cause of mild coldlike symptoms but it can be dangerous for infants and older people.

Cohen was asked about pneumonia cases in children reported in Massachusetts and in Warren County, Ohio, near Cincinnati. There are a number of possible causes of the lung infection, and it can be a complication of COVID-19, flu, or RSV.

In Ohio, health officials have reported 145 cases since August and most of the children recovered at home. The illnesses were caused by a variety of common viruses and bacteria, officials said.

Massachusetts health officials said there’s been a modest increase in pneumonia in kids but that it is appropriate for the season.

China recently had a surge in respiratory illnesses which health officials there attributed to the flu and other customary causes.

China’s surge in respiratory illness is caused by known pathogens and there is no sign of new infectious diseases, a health official said Saturday as the country faces its first full winter since lifting its strict COVID-19 restrictions.

The spike in illness in the country where COVID emerged in late 2019 attracted the spotlight when the World Health Organization sought information last week, citing a report of clusters of undiagnosed pneumonia in children.

Chinese authorities will open more pediatric outpatient clinics, seek to ensure more elderly people and children receive flu vaccines and encourage people to wear masks and wash their hands, Mi Feng, an official with China’s National Health Commission, told a press conference.

Doctors in China and experts abroad have not expressed alarm about China’s outbreaks, given that many other countries saw similar increases in respiratory diseases after easing pandemic measures, which China did at the end of last year.

On Friday, five Republican senators led by Marco Rubio asked President Joe Biden’s administration to ban travel between the United States and China after a spike in Chinese respiratory illness cases.

A Biden administration official said the United States was closely monitoring the uptick in respiratory illnesses in China, but added, “We are seeing seasonal trends. Nothing is appearing out of the ordinary. … At this time, there is no indication that there is a link between the people who are seeking care in U.S. emergency departments and the outbreak of respiratory illness in China.”

Maria Van Kerkhove, acting director of the WHO’s department of epidemic and pandemic preparedness and prevention, said earlier this week the increase appeared to be driven by a rise in the number of children contracting pathogens that they had avoided during two years of COVID-19 restrictions.

The spokesperson for the Chinese Embassy in Washington, Liu Pengyu, said in response to the Rubio letter, “The relevant claims are purely ill-intentioned fabrications. China firmly opposes them.”

Rubio’s letter was also signed by Senators J.D. Vance, Rick Scott, Tommy Tuberville and Mike Braun.

A small western Pennsylvania water authority was just one of many organizations breached in the United States by Iran-affiliated hackers who targeted a specific industrial control device because it is Israeli-made, U.S. and Israeli authorities say.

“The victims span multiple U.S. states,” the FBI, the Environmental Protection Agency, the Cybersecurity and Infrastructure Security Agency, known as CISA, as well as Israel’s National Cyber Directorate said in an advisory emailed to The Associated Press late Friday.

They did not say how many organizations were hacked or otherwise describe them.

Matthew Mottes, the chairman of the Municipal Water Authority of Aliquippa, which discovered it had been hacked on Nov. 25, said Thursday that federal officials had told him the same group also breached four other utilities and an aquarium.

Cybersecurity experts say that while there is no evidence of Iranian involvement in the Oct. 7 attack into Israel by Hamas that triggered the war in Gaza, they expected state-backed Iranian hackers and pro-Palestinian hacktivists to step up cyberattacks on Israeli and its allies in its aftermath. And that has happened.

The multiagency advisory explained what CISA had not when it confirmed the Pennsylvania hack Wednesday — that other industries outside water and water-treatment facilities use the same equipment — Vision Series programmable logic controllers made by Unitronics — and were also potentially vulnerable.

Those industries include “energy, food and beverage manufacturing and healthcare,” the advisory says. The devices regulate processes including pressure, temperature and fluid flow.

The Aliquippa hack promoted workers to temporarily halt pumping in a remote station that regulates water pressure for two nearby towns, leading crews to switch to manual operation. The hackers left a digital calling card on the compromised device saying all Israeli-made equipment is “a legal target.”

The multiagency advisory said it was not known if the hackers had tried to penetrate deeper into breached networks.

The advisory says the hackers, who call themselves “Cyber Av3ngers,” are affiliated with Iran’s Islamic Revolutionary Guards Corps, which the U.S. designated as a foreign terrorist organization in 2019.

The group targeted the Unitronics devices at least since Nov. 22, it said.

An online search Saturday with the Shodan service identified more than 200 such internet-connected devices in the U.S. and more than 1,700 globally.

The advisory notes that Unitronics devices ship with a default password, a practice experts discourage as it makes them more vulnerable to hacking. Best practices call for devices to require a unique password to be created out of the box. It says the hackers likely accessed affected devices by “exploiting cybersecurity weaknesses, including poor password security and exposure to the internet.”

In response to the Aliquippa hack, three Pennsylvania congressmen asked the U.S. Justice Department in a letter to investigate. Americans must know their drinking water and other basic infrastructure is safe from “nation-state adversaries and terrorist organizations,” U.S. Sens. John Fetterman and Bob Casey and U.S. Rep. Chris Deluzio said.

Cyber Av3ngers claimed in an Oct. 30 social media post to have hacked 10 water treatment stations in Israel, though it is not clear if they shut down any equipment.

Unitronics has not responded to the AP queries about the hacks.

The attack came less than a month after a federal appeals court decision prompted the EPA to rescind a rule that would have obliged U.S public water systems to include cybersecurity testing in their regular federally mandated audits. The rollback was triggered by a federal appeals court decision in a case brought by Missouri, Arkansas and Iowa, and joined by a water utility trade group.

The Biden administration has been trying to shore up cybersecurity of critical infrastructure — more than 80% of which is privately owned — and has imposed regulations on sectors including electric utilities, gas pipelines and nuclear facilities. But many experts complain that too many vital industries are permitted to self-regulate.
