How Tunisia's trade unions became Kais Saied's most powerful opponent

In-depth: A nationwide strike in June saw Tunisia grind to a standstill as the country's largest trade union continues to challenge IMF-linked austerity measures and the president's concentration of powers.


A national strike staged by a Tunisian labour union this month signals strong mobilisation potential in the face of the government's economic reform plan and President Kais Saied’s non-inclusive dialogue.

The general strike held by Tunisia’s largest trade union (UGTT) on 16 June, which saw over 96 percent of public employees from 159 state institutions and public companies halting work nationwide, was a test for president Saied after the UGTT’s rejection of a reform package announced by his government.

The strike was in response to an austerity proposal to secure a major loan from the International Monetary Fund that included the freezing of salaries and jobs in the public sector, the lifting of subsidies, and the privatisation of state-owned firms.

The mass mobilisation protested the decision of Najla Bouden's cabinet not to increase public wages and to propose spending cuts, as well as to add pressure on the president, who’s taking steps to prepare a new constitution that will be put to a referendum on 25 July.

“The message directed at the head of state was that the union is a main stakeholder, and nothing will happen unless it is included in the process,” Tunisian economist Aram Belhadj told The New Arab.

"The UGTT's strike action is a huge challenge to Saied amid continued political and social turmoil, one of the largest crises the Tunisian leader has faced since he assumed full powers last July"

The day before the strike, the UGTT stated that public workers would walk out “to defend their economic and social rights” and denounced the deterioration of their living standards due to rampant inflation and declining purchasing power.

Serife Akinci, an expert on Middle East and African Economies Studies at the Center for Middle Eastern Studies (ORSAM), suggested that economic activity in Tunisia may be “disrupted” by more action in the near future if demands remain unheard, possibly threatening the country’s stability, which the head of state “won’t be able to ignore”.

The national strike aimed to pressure the president on wage increases and other social demands, coinciding with Tunisia’s negotiations with the IMF for a $4 billion loan.

Whether it will succeed in convincing the government to return to the negotiating table is an open question. Despite a last-minute discussion on 13 June between the powerful labour union and the ministry of social affairs, the parties failed to reach an agreement and the public-sector strike went ahead as planned three days later.

Riccardo Fabiani, North Africa project director for the International Crisis Group (ICG), observed that the crucial issue in the talks with the IMF is whether the Tunisian government can give guarantees.

“It’s unrealistic to expect an accord in the current context of crisis and tension, except if there’s a push from international actors [US or Europe] to unlock funding without requiring major conditions,” the political analyst told The New Arab, although he thinks such a scenario is hard to envision.

Belhadj pointed out that given Tunisia’s failure to uphold its obligations in the past the IMF is now demanding a consensual agreement between the executive and the labour union along with other requirements.

In his view, the formal negotiations for a rescue plan, which the IMF is ready to begin in the coming weeks, will pass through “further complications” even if a deal is signed as, he argued, the union will continue to oppose spending cuts.

The North African country has been in preliminary discussions with the global lender since the start of 2022 but progress seems to have stalled. It hopes to secure a badly needed deal - the third in a decade - to address the state’s massive budget deficit at 10% of GDP.

The UGTT’s strike action is a huge challenge to Saied amid continued political and social turmoil, one of the largest crises the Tunisian leader has faced since he assumed full powers last July.

The social mobilisation was inevitably political too, coming in the midst of heavy criticism against the head of state for excluding opposition forces from his ‘national dialogue’ to draft the new charter.

The million-member labour confederation had earlier refused to participate in the debate, which excludes the county’s main political parties and several civil society groups. The union’s secretary-general Noureddine Taboubi has repeatedly criticised Saied’s “unilateralism”, and demanded an inclusive dialogue.

While president Saied stays focused on his political project, accelerating his constitutional reform for what he has called a "new republic", Tunisians largely appear uninterested in his vision and more preoccupied with the collapsing economy and soaring food prices.

Less than 10 percent of Tunisian citizens took part in the national e-consultation on the new constitution. Critics say that Saied lacks an economic or social program to lead the country out of the current crisis.

For its part, the UGTT, a key actor in the debate on the transition and socio-economic reforms in Tunisia, has political leverage and the ability to mobilise the street and obstruct Saied. Added to that, it is very unlikely that the international lender will negotiate a bailout deal without its backing given that the IMF has made any new loan conditional on the trade union’s support for the government reform plan.

“Kais Saied’s room for manoeuvre for an agreement over a rescue package is very limited. It doesn’t seem possible for him to ignore a major player with veto power,” Akinci told The New Arab. She explained that bypassing the labour organisation would translate to a lack of consensus on economic reforms and undermine the chance to restore confidence among international creditors, causing talks with the IMF to reach a stalemate.

“Saied is aware that the UGTT is important to him at this point in time,” the MENA economist said. “He realises that concluding an accord with the union involvement would strengthen his credibility abroad and significantly increase the likelihood of an IMF funding arrangement”.

Yet, if the government or the president do not respond to the trade union’s pressure, she continued, larger strikes could follow adding a “new dimension” to the deepening political and economic crisis.

"It's unclear what the impact of the 16 June strike on Saied will be, but we can consider the UGTT's move a run-up to wider-scale mobilisation in the country, with different workers' groups joining"

The ORSAM specialist noted that such labour actions could potentially “bring the country's economy to a standstill”, which would in turn have negative repercussions on Tunisian lives and compromise the confidence of international donors.

Fabiani hinted that an eventual option for the UGTT could be choosing to apply its full political weight in future strike action, though he reiterated that union members appear to be more focused on fulfilling socio-economic objectives.

The ICG’s North Africa expert stressed that the president’s individualistic modus operandi is “detrimental” to dialogue with social partners as well as the possibility of an accord with the IMF, as he hardly makes any concessions and pays little attention to the country’s economic priorities.

“It’s unclear what the impact of the 16 June strike on Saied will be, but we can consider the UGTT’s move a run-up to wider-scale mobilisation in the country, with different workers’ groups joining,” the analyst maintained.

Discussing the union’s negotiating power, Fabiani contended that the UGTT carries less influence in today’s context of no-dialogue with the presidency, whereas its mobilisation is more widespread and participative than in the past given mounting frustration with the country’s worsening outlook.

“The UGTT’s ability to achieve results is reduced, but it has greater power to mobilise the public,” he said. “If there’s no explicit move from the chief of state to initiate a dialogue with the UGTT, we’re going to see more social mobilisations in the following weeks,” Belhadj said. “The ball is in the president’s court”.

The economic expert claimed that the reform programme, as it stands, is “inapplicable” for various reasons, namely the unstable economic environment, a lack of consensus from the UGTT, and Tunisians’ resistance to unpopular cuts to subsidies. Bouden's government announced earlier this month plans to start cutting energy and food subsidies from 2023.

In addition, he said, Saied’s focus on his transition roadmap at the expense of socio-economic questions does not facilitate the applicability of the reform agenda.

During this week’s visit to Tunisia by IMF Middle East director Jihad Azour, president Saied urged the fund to take into account the social impact of any economic reforms it demands as part of a financial aid package. Azour in turn urged the government to discuss the proposed reforms “with all stakeholders”, reiterating that the UGTT’s consent is essential to the bailout.

Sudanese migrant’s dream dies on Melilla border fence

37 migrants dead while attempting to cross from Morocco into Spain enclave of Melilla

Khaled Majdoub |28.06.2022


RABAT, Morocco

Sudanese migrant Mohamed Ismail has left his country to Morocco in the hope of finding a better job. His hope, however, ended up in injuries from bullets fired by Moroccan security forces.

Ismail departed Sudan through the border into several countries until he landed in Morocco six months ago. There, he helplessly tried hard to find work to make a living, but to no avail.

Losing any hope to find a good job opportunity, he decided to join hundreds of migrants in crossing the militarized border fence between Morocco and the Spanish enclave of Melilla, but they were met with force from both Moroccan and Spanish security forces.

Initial reports indicated five were killed in last week’s violence, but Moroccan authorities later raised that figure to 23. Helena Maleno Garzon, head of the NGO Walking Borders, says at least 37 people lost their lives.

Videos from the Moroccan side of the border show what appear to be dead bodies and severely injured people strewn across the ground without receiving medical attention.

Other images show hundreds of people, some with clear injuries, lying in a pile on the ground with their hands tied behind their backs.

Among those injured was Ismail, who was shot and injured by rubber-coated bullets.

“I came to Melilla in search for work and to cross into Spain,” Ismail told Anadolu Agency.

He recalled that the situation suddenly turned into violence when police tried to prevent migrants from crossing the border fence.

“The migrants did not use violence,” Ismail said.

According to Spanish news agency EFE, dozens of Moroccan and Spanish police officers were also injured during the storming of the border, where migrants were armed with homemade knives, as well as sticks, stones, and hooks to climb the border fence.

Following the violence, Ismail was deported by Moroccan authorities to the city of Beni-Mellal, 600 kilometers far from Melilla.

“I have no idea why I was deported,” he said.

Moroccan authorities have deported hundreds of migrants to other cities in an attempt to prevent any future attempt by them to cross into Spain.

On Saturday, several non-governmental organizations have demanded a probe into the treatment of migrants during their attempt to cross the border.

The attempt was the largest mass movement on the border since Spain and Morocco boosted bilateral cooperation after Madrid decided to support Rabat's position on the independence of Western Sahara.
Cop15: lack of political leadership leaves crucial nature summit ‘in peril’, warn NGOs

Nairobi biodiversity talks end in stalemate, prompting open letter to world leaders calling for action before Montreal conference

Tue 28 Jun 2022 

UN biodiversity negotiations have reached crisis point due to a lack of engagement from governments, leading NGOs have warned, three years after experts revealed that Earth’s life-support systems are collapsing.


Last week, countries met in Nairobi for an extra round of talks on an agreement to halt the human-driven destruction of the natural world, with the final targets set to be agreed at Cop15 in Montreal. Governments have never met a target they have set for themselves on halting the destruction of nature despite scientists warning in 2019 that one million species face extinction, and that nature is declining at rates unprecedented in human history.


While world leaders including Emmanuel Macron, Justin Trudeau and Boris Johnson have underscored the importance of the summit, which only takes place once a decade, the biodiversity negotiations have seen substantial divisions between the global north and south over money, proposals to protect 30% of land and sea by 2030, and implementation of any agreement. The Africa group warned it would not sign off the final post-2020 global biodiversity framework unless it includes a target on digital biopiracy.

In an open letter published on Monday, environmental groups including Greenpeace, Avaaz, the Campaign for Nature and the International Indigenous Forum on Biodiversity said progress on the final deal was not being made, and the talks lacked high-level political engagement. In the run-up to any Cop, negotiations are largely handled by technical specialists in the initial phases, with ministers typically getting involved at the end of talks.

The letter calls on the UN secretary general, António Guterres, and government ministers to inject political leadership into the process and avert disaster at Cop15 in Montreal in December. China will oversee the event as president after its zero-Covid policy forced organisers to move the summit earlier this month.

“Negotiations have become stagnant, and the post-2020 global biodiversity framework is in peril,” the letter reads. “Countries had once pointed to Cop15 as an opportunity to deliver a global deal for nature and people, similar in significance to the Paris climate agreement, but there is a notable absence of the high-level political engagement, will and leadership to drive through compromise and to guide and inspire the commitments that are required.”

During six days of talks last week, negotiations saw little agreement among countries over the final text, which includes draft targets on eliminating environmentally harmful subsidies, reducing pesticide use, and action on invasive species in an effort to cut extinction rates. Scientists warned again in 2020 that the sixth mass extinction of wildlife on Earth is accelerating.

A further round of pre-Cop15 talks has been scheduled in the days before the summit, which starts on 5 December and concludes on 17 December, the day before the football World Cup final.

If adequately funded and implemented in full, the agreement could see major changes to global agricultural practices and extractive industries, both major drivers of the eradication of wildlife and natural ecosystems.

It had been hoped that countries would use the extra round of talks in Nairobi to hammer out points of division ahead of Cop15. Yet one negotiator, speaking to the Guardian on the condition of anonymity, said they left the talks seeing more division.

“When the meeting ended yesterday, everyone was really frustrated. Many people were expecting to move forward, at least on some of the targets. It should be a wake-up call and might raise awareness among ministers that they need to find a way out of this conundrum,” they said.

Elizabeth Maruma Mrema, the UN’s biodiversity head, urged governments to work together on the agreement ahead of Cop15 to help reach consensus. “I call upon the parties, in the next months, to vigorously engage with the text, to listen to each other and seek consensus,” she said.

Basile van Havre, a co-chair for the UN convention on biological diversity (CBD) negotiations, said he was not as negative as others about the state of talks but agreed that ministerial input was important. “People came prepared. Delegates worked really hard and there was no blocking. The challenge we have is that there are a lot of difficult issues.

“We made progress but we are not where we need to be. We need ministers to get involved and give negotiators technical mandates to advance,” he said.
Top talking points from Nairobi

A quiet China When delegates travel to Montreal this December, Beijing will still hold the presidency of the much delayed Cop, even though it will be hosted from Canada, not Kunming as originally planned. China has so far played a largely passive role in negotiations and did so again in Nairobi.

African scepticism on 30x30 Several world leaders have put forward proposals to protect 30% of land and sea as a key target of the agreement. But many African countries have indicated that the goal will not make the final text without a substantial financial commitment from the wealthy global north.

Brazil accused of undermining talks At the end of the talks on Sunday, Marco Lambertini, director general of WWF International, accused Brazil of “actively working to undermine the negotiations”. Cop15 could become another chance for Bolsonaro to add to his destructive environmental legacy.
G7 proposal for publicly funded gas projects “a catastrophically bad idea”

28th June 2022, Brussels - Responding to the G7 proposal to use tax money to fund fossil gas projects, Murray Worthy, gas campaign leader at Global Witness said:

“Building new fossil gas terminals and pipelines is a catastrophically bad idea and will only mean one thing: hooking the world onto this dangerous fossil fuel for the long term. Energy experts have shown that Europe doesn’t need more infrastructure to replace Russian gas, and climate scientists say the climate absolutely can’t afford it.”

“Rather than trashing the commitment to stop funding fossil fuels that were made at the UN climate talks last year, governments should be doubling down on them. Instead of using public money to fund further dependence on fossil gas, governments should be pulling out all the stops to phase it out once and for all with an emergency build-out of renewables and insulation projects.”

A lump of amber on display in Gdansk is set to enter the record books as the world's biggest piece of amber, after it weighed in at 68kg 200g.

The piece, which will now enter the Guinness Book of Records, was officially weighed and measured at the city's Museum of Amber to mark World Amber Day.

The record weigh breaking-in was attended by representatives of the Gdansk authorities, amber craftsmen and representatives of the Regional Office of Measures in Gdansk and officials from the Guinness Records Office.

Worth an estimated PLN 140,000 (EUR 29,803) the piece comes from the Indonesian island of Sumatra.

The record weigh breaking-in was attended by representatives of the Gdansk authorities, amber craftsmen and representatives of the Regional Office of Measures in Gdansk and officials from the Guinness Records Office.

Waldemar Ossowski, director of the Gdansk Museum, said that a piece of amber is not just a small thing that can be found after a storm somewhere on the beach on Sobieszewo (a Polish island in the Baltic Sea - PAP), but can also weigh several dozen kilograms.

The piece will now enter the Guinness Book of Records.

"Amber is discovered not only here, but practically on every continent. It can be 2 million years old or over 100 million," he said.

Before Tuesday's weigh-in the huge lump was removed from its glass cabinet and placed on a scale.

Ossowski said that it was fitting that it was weighed and measured on World Amber Day (June 28th).

"This is an important day for everyone who loves amber and we are glad that on this holiday we were able to set a new record," said the museum's director.

Although the record for the largest lump of amber has been established, it will still have to wait about a week for the record to be officially confirmed and entered into The Guinness Book of Records.

The piece can be seen at the Amber Museum of Gdansk, located in the city's Grand Mill.
Decades-old mystery solved after satellite shows ‘Bluetooth Viking king’ IS buried in Polish village

TFN REPORTER JUNE 28, 2022
Using satellite remote sensing tools, researchers say they have now solved ‘one of history’s most enduring mysteries’ and confirmed that a large Viking Age burial mound in the village of Wiejkowo did belong to the 10th century king of Denmark and Norway, Harald Gormsson Bluetooth.Marek Kryda/Public domain

The long-lost burial site of a Viking king whose name was the inspiration for Bluetooth wireless technology has been found in a village in Poland.

Using satellite remote sensing tools, researchers say they have now confirmed that a large Viking Age burial mound in the village of Wiejkowo, belonged to the 10th century king of Denmark and Norway, Harald Gormsson Bluetooth.

Lead researcher Marek Kryda, author of the best-selling book Viking Poland, told TFN: ‘The death and possible burial site of the Danish king Harald Gormsson Bluetooth was until now one of history’s most enduring mysteries.

 
The discovery confirms earlier speculation by Swedish archaeologist Sven Rosborn who suggested the Viking king was buried in the area following the 2014 discovery of a gold disc known as the Curmsun disc. Marek Kryda

‘The space-based reconnaissance allowed us to look at large swaths of landscape and find archaeological disturbances within the land, some as small as 12 inches (30.5 centimeters) long.

‘In a discipline where discovery was traditionally confined to a two-meter-square excavation, 21st-century technology satellite imagery has helped to make a breakthrough discovery of the possible burial mound of Harald Bluetooth.’

Gaining the nickname Blåtand meaning blue tooth, because he had a dead tooth that was dark blue, King Harald was credited with uniting the Scandinavian countries by introducing Christianity.

The discovery now confirms earlier speculation by Swedish archaeologist Sven Rosborn who suggested the Viking king was buried in the area following the 2014 discovery of a gold disc known as the Curmsun disc.

The disc’s Latin inscription mentioned the Viking king as the ‘ruler of Danes, Scania and the Viking fortress of Jomsborg’, which is today the town of Wolin just 3.5 miles west of the Wiejkowo burial mound.

According to Rosborn, the Curmsum disc, which he believed was a ‘grave gift’, was originally discovered alongside skeletal remains and a stash of other valuables in 1841 in a stone burial chamber underneath the current building of the local church in Wiejkowo.

The hoard was left in the crypt until 1945, when a Polish army major called Stefan Sielski entered and seized what was left of it.

Hiding it in a chest with old buttons it wasn’t until 2014 that his 11 year old great-granddaughter found it and showed it to her history teacher.

That sparked a chain reaction which led to the disc’s inscription being revealed.

But doubts about whether the king actually died and was buried in the village have divided archaeologists.

Kryda said: ‘There’s no doubt that the golden Wiejkowo disc found in the tomb is an extraordinary find.

“However it's worth mentioning that Rosborn's strong suggestion that Bluetooth was buried in Wiejkowo was not based on research on the ground in Wiejkowo.

“Instead, his suggestion was based solely on the research of the Curmsun Disc and Sielski family archives in Sweden.

“Without hard scientific evidence collected on the ground in Wiejkowo, Rosborn's theory was just a well-documented guess and suggestion.”

He added: “The satellite research fully confirmed the existence of a large Wiejkowo Mound, and of course at the same time confirmed that Wiejkowo is the burial site of Bluetooth.

Viking expert Marek Kryda said: “The satellite research fully confirmed the existence of a large Wiejkowo Mound, and of course at the same time confirmed that Wiejkowo is the burial site of Bluetooth. And that would mean that only the burial mound is his real grave, the original church was only a later addition to it. Using Ground-Penetrating Radar Imagery will help us see what was inside.”Marek Kryda

“And that would mean that only the burial mound is his real grave, the original church was only a later addition to it.

“According to Danish archivist Steffen Harpsøe, the disc may have been created over 70 years after Bluetooth's burial by local priests around Jomsborg and Wiejkowo between 1050-1125 - and only then placed in his Royal crypt.

“Using Ground-Penetrating Radar Imagery will help us see what was inside.”

Indonesian zoo breeds dozens of endangered baby Komodo dragons

An Indonesian zoo has welcomed dozens of new baby Komodo dragons hatched in captivity in recent months as part of a breeding programme, its director said Tuesday, offering hope for efforts to conserve the endangered species.

The world's largest living lizards are found only in Indonesia's World Heritage-listed Komodo National Park and neighbouring Flores, and just 3,458 adult and baby species are left in the wild according to estimates.

The fearsome reptiles, which can grow to three metres (10 feet) in length and weigh up to 90 kilograms (200 pounds), are threatened by  and  destroying their habitat.

But a breeding programme in Indonesia's second-largest city of Surabaya is trying to change that, successfully breeding 29 dragons in incubators between February and March.

"We have habitats that mirror the Komodo's natural habitat, including its humidity and temperature," zoo director Chairul Anwar told AFP.

The newborns were hatched from two female Komodo dragons after their eggs were placed in incubators to prevent them from being eaten by their mothers or other Komodo dragons.

Female Komodos can fertilise an egg without the need for a male dragon.

The zoo started the programme in the 1990s as part of the effort to conserve the species in a city located more than 700 kilometres (434 miles) away from the dragon's .

After the spate of births this year, Surabaya Zoo now houses 134 Komodo dragons, the largest population group outside of its habitat in the cluster of islands east of Bali, Anwar said.

In a report last year, the International Union for the Conservation of Nature warned the ' habitat was expected to shrink by 30 percent in the next 45 years due to rising sea levels.

Anwar said the dragons will not be released back into the wild on Komodo or Flores until conditions improve.

"Komodo Island is still working to rejuvenate the forests," which feed the dragon's declining natural prey such as deer, he said.Why we must reassess the komodo dragon's endangered status

How did vertebrates first evolve jaws?

Five-hundred million years ago, it was relatively safe to go back in the water. That’s because creatures of the deep had not yet evolved jaws. In a new pair of studies in eLife and Development, scientists reveal clues about the origin of this thrilling evolutionary innovation in vertebrates.

In the studies, Mathi Thiruppathy from Gage Crump’s laboratory at USC, and collaborator J. Andrew Gillis from the University of Cambridge and the Marine Biological Laboratory, looked to embryonic development as way to gain insight into evolution—an approach known as “evo-devo.”

In fishes, jaws share a common developmental origin with gills. During development, jaws and gills both arise from embryonic structures called “pharyngeal arches.” The first of these arches is called the mandibular arch because it gives rise to jaws, while additional arches develop into gills. There are also anatomical similarities: the gills are supported by upper and lower bones, which could be thought of as analogous to the upper and lower jaws.

“These developmental and anatomical observations led to the theory that the jaw evolved by modification of an ancestral gill,” said Thiruppathy, who is the eLife study’s first author and a PhD student in the Crump Lab. “While this theory has been around since the late 1800s, it remains controversial to this day.”

In the absence of clear fossil evidence, the eLife publication presents “living” evidence in support of the theory that jaws originated from gills. Nearly all fishes possess a tiny anatomical structure called a “pseudobranch,” which resembles a vestigial gill. However, this structure’s embryonic origin was uncertain. 

Using elegant imaging and cell tracing techniques in zebrafish, Thiruppathy and her colleagues conclusively showed that the pseudobranch originates from the same mandibular arch that gives rise to the jaw. The scientists then showed that many of the same genes and regulatory mechanisms drive the development of both the pseudobranch and the gills.

In a related study just published in Development, Gillis and his Cambridge colleague Christine Hirschberger show that skates also have a mandibular arch-derived pseudobranch with genetic and developmental similarities to a gill. While zebrafish are bony fish, skates represent an entirely different evolutionary class of jawed vertebrates: cartilaginous fish.

“Our studies show that the mandibular arch contains the basic machinery to make a gill-like structure,” said Crump, the eLife study’s corresponding author, and a professor of stem cell biology and regenerative medicine at the Eli and Edythe Broad Center for Regenerative Medicine and Stem Cell Research at the Keck School of Medicine of USC. “This implies that the structures arising from the mandibular arch—the pseudobranch and the jaw—might have started out as gills that were modified over the course of deep evolutionary time.”

Gillis, who is the corresponding author of the Development study and a co-author on the eLife study, added: “Together, these two studies point to a pseudobranch being present in the last common ancestor of all jawed vertebrates. These studies provide tantalizing new evidence for the classic theory that a gill-like structure evolved into the vertebrate jaw.”

Peter Fabian, a postdoctoral trainee in the Crump Lab at USC, is also a co-author on the eLife study.

Ninety-seven percent of the support for the eLife study came from federal funding from the National Institute of Dental and Craniofacial Research (grants R35DE027550, F31DE030706, and K99DE029858). The remaining funding came from the Royal Society (RGF/EA/180087) and the University of Cambridge (14.23z). 

The Development study was funded by the UK Biotechnology and Biological Sciences Research Council (BBSRC), The Royal Society, and the Isaac Newton Trust.

Safe period trackers: Open source apps protect your data

With the US ending constitutional rights to abortion, people have voiced concern over apps that track menstruation cycles. But some apps do protect privacy.



Why expose yourself and data about your body when you can use a non-commercial period tracker?

As a late adopter of smartphones, Marie Kochsiek couldn't help but feel excited the first time she encountered the millions of apps available on the market.

Period tracking apps, especially, caught her attention. Finally, she thought, she wouldn't need to manually fill in the papers her gynecologist handed her after every visit, but instead she could digitally monitor her menstrual cycle.

"I was so excited back then that I told a friend about it. She asked me if I was sure it was a safe option. She was involved in internet politics," Kochsiek recalls.

Behind the pink interfaces and mascots, some apps track more than a user's period. They often have access to a user's name, location, email address, browsing history and more — all to provide targeted advertising.
Protect your data: Alternative period trackers

When reports started to emerge on how these apps monetize and sell user information to third parties, Kochsiek was concerned but refused to go back to the old analog way.

Instead, Kochsiek felt motivated to develop an alternative app called .drip—a cycle tracker that only stores data on your device.

As with other cycle apps, .drip allows users to monitor their menstrual health and keep track of their flow and fertile days.


Period trackers track more than your cycle — some commercial apps have been found to sell on sensitive data to social media platforms for advertising purposes

The difference is that users don't have to agree to invasive practices, such as permitting an app to access their microphone or having intimate data, like sexual encounters or a week of heavy menstrual flow, stored on a company's servers many miles away from them.

But the popularity of non-commercial trackers lags far behind bigger players like Mi Calendario Menstrual, Flo and Clue, which add up to 160 million downloads across mainstream app stores.

Period trackers since Roe vs. Wade was overturned

The US Supreme Court's decision to reverse Roe vs. Wade, a 1973 decision establishing a federal — and constitutional — right to terminate a pregnancy, has sparked new fears about the things that companies do with menstrual data.

"It seems as if these [popular] companies have more to gain from me tracking my menstrual cycle than what I get as an individual. The gain for their commercial business is larger," says Julia Kloiber, co-founder of SUPERRR Lab, a feminist organization advocating for equal digital futures.

For Kloiber, non-commercial trackers pose a safer option to track periods. "It's important that these alternatives are being developed so people have the option to switch," Kloiber says.
Open source: More privacy and inclusion

More free and non-commercial alternatives have entered the market in the past few years. They are steering the conversation toward data protection, but also shifting it away from the mass-market approach for these apps.

And that is allowing for space for people with varied identities and needs.

Take for example Periodical, a gender-neutral tracker that works offline and only stores data on your phone or memory card. Like .drip, Periodical is open source, which means that the code behind the app is free to share and check for data security issues, for instance.

Open source technology stays in conversation with the community, says Kochsiek.

"It's not a blackhole code. When we talk about periods, we talk about women's health, about our bodies, so the conversation should be transparent and people should be able to join the discussion," says Kochsiek, the co-founder developer of .drip.


Concern about the US overturning constitutional rights on abortion spread internationally — here, demonstrators gathered in Berlin

Meanwhile, Hamdam is the first period tracker in Farsi and the only one equipped with the Persian Jalali Calendar. The app provides Iranian users with information on women's rights, domestic violence and sexual health.

On June 13, a Spanish tech non-profit called Eticas released a report analyzing the privacy practices of 12 popular fertility apps. The report concluded that only one of them, WomanLog, didn't sell or share user data under any circumstance.

Other apps like Euki, Stardust and Clover also featured among the top-ranked apps. Euki lets users create a personal PIN to access their data on the app.
Tracking more than periods

Research into period trackers and their use of personal data goes back a few years.

In 2019, a UK-based charity, Privacy International, warned how five period trackers shared user data with Facebook and other third parties for commercial purposes.

A year later, the charity filed data requests to another handful of apps and concluded that the data the apps collected was accessible via company servers, making them vulnerable to leaks.

While collecting menstrual data may promote research in a field as understudied as women's reproductive health, Kloiber says the lack of transparency and compliance with data protection frameworks in tech could also pose a risk.

"At a first glance, it's just some data points that don't say a lot about a person. But this [situation in the US] shows that data that seems banal at first needs to be protected because if the political climate shifts, it can turn sensitive," Kloiber says.

Digital rights activists warn that data from period trackers could be used by prosecutors not only in the US, where some federal states were quick to introduce abortion bans after the Supreme Court ruling, but also in Europe, in countries such as in Poland, where terminating a pregnancy is illegal.

"If a woman in the US gets an abortion, authorities could ask [the company behind] the app to provide data that can be used against her," researcher and founder of the Eticas Foundation, Gemma Galdon, says.

And that data could be something as simple as googling for an abortion clinic.

"That information could also be used by their family or their partner," Galdon says. "There are a lot of risks concerning the use of this data and [some people] are not aware of it."

KNOW YOUR BELLY BUTTON
A near-universal lint trap
It's not strictly true to say we all have a belly "button" — an outward looking bump. And some people appear to have nothing at all, often after surgery for a hernia. But we all have a "navel," a spot that marks where our umbilical cords were attached when we were in our mother's womb. The cord gets cut when we're born, leaving a bit of it to heal, dry and close, and we get a belly button.


Rewilding – The Fine Art Of Doing Nothing

Sit back, relax and let nature do the work.

Rewilding is a progressive conservation concept with many different approaches. The idea is to restore natural healthy ecosystems to the point at which nature’s processes can take over. This initial restoration can include the reintroduction of keystone species, which are organisms (often predatory animals) that fill an ecological niche. 

Large grazers can also be introduced to manage vegetation, and non-native plants can be removed. Removal of human-made structures that function to change the natural landscape also allows the environment to naturally re-shape. 

After these implementations, humans can sit back and let the habitat develop into a natural cycle created by the organisms that live there. 

Unfortunately, many species have been lost from their native habitats due to hunting, urbanization, and climate change. Rewilding works to bring back those lost species and enable them to carry out their ecological functions once more. Keystone species like wolves and beavers can alter the fauna of an area, restoring ecological niches so organisms can thrive and the ecology of an area can start to be repaired. 

The reintroduction of 41 wolves to Yellowstone National Park between 1995 and 1997 was an understandably concerning endeavor, but large predators are vital to maintaining a healthy ecosystem. The wolves are hard at work keeping the elk population under control. Before the wolves were brought back, the elk did not naturally move through the park, causing the willow along the banks of the river to become heavily overgrazed. 

Now with a wolf population to influence the elk distribution, the willow can flourish. This leads to an increased beaver population which relies on the willow branches to survive in winter. 

Talking of beavers, in a 2017 rewilding effort, a family of two adults and two kits were introduced into the Forest of Dean, UK. In the five years since, the area has already benefited from the creation of natural flood defenses and improvements to the soil. The porous nature of beaver dams benefits not only the ecology of the area, but also the people living nearby – beavers are pretty *dam* handy at creating effective, sustainable, and cheap flood defenses. 

It is well documented that spending time in nature is massively beneficial for human mental and physical health and wellbeing. Rewilding native areas means more land is protected for people to enjoy, not to mention the resources that are conserved during the natural process that take place. It is important to remember that there is no fixed goal with rewilding, it is simply about letting nature take the lead.
