'I'll die with no regrets': risking their lives in Mediterranean

People are told to board the boats in the middle of the night. "You can't see anything. It's dark and scary. But you know you'll die in Libya if you don’t leave," Saruna, 17, said.
"You call home before you leave. You don't know if you'll survive at sea. You just pray to God and go."

Aboard the Ocean Viking in the Mediterranean Sea - Since 2016, almost 12,000 refugees and migrants have drowned in the Mediterranean while trying to reach Europe.

Libya acts as a major gateway for African refugees and migrants.

There are currently more than 636,000 refugees and migrants in Libya, mostly from neighbouring countries and sub-Saharan Africa, according to the International Organization for Migration (IOM).

These people are often fleeing poverty, conflict, forced labour and other threats to their lives and wellbeing.

Many suffer abuse and extortion en route and their arrival in Libya rarely marks the end of the dangers they face.

"You see this," Karim, a rescued migrant, told Al Jazeera while pointing to his shoulder.

"This is where a Libyan stabbed me when I asked for money for the work I did for him.”
He then pointed to his right leg.
"This is where I was shot while waiting for work in Tripoli. There is complete lawlessness there. Everyone has guns and knives. There are no rights for black people, even someone who has been stabbed or shot."

Florent, from Cameroon, was another migrant rescued from an overcrowded rubber boat in distress in the Mediterranean after he managed to escape Libya.
"If I die right now, I'll die with no regrets. I've managed to escape Libya. It was hell. Nothing less than hell," he said.

"In life when you've lost everything, you're not scared of anything any more," said Saou, sharing his reasons for getting on a boat for a journey that could have well been his last.
In addition to the deaths, almost 9,000 people were intercepted by the Libyan coastguard and returned to detention centres last year.
More than 110,000 migrants and refugees arrived in Europe by sea last year but 1,283 of those who left North Africa died in the Mediterranean after managing to flee Libya.
"It seems there's complete disregard for human life and people dying on the Mediterranean," said Nicholas Romaniuk, a search and rescue coordinator on board the rescue vessel Ocean Viking.
The UN has warned "there will be a sea of blood" without the intervention of rescue NGOs in the Mediterranean.
Since it began its operations in August 2019, the Ocean Viking has managed to rescue more than 1,100 people.
But in the past, ships have been accused of trafficking people into Europe and some rescuers faced up to 20 years' imprisonment in Italy after they were accused by officials of assisting traffickers and aiding illegal immigration.
Relieved migrants and refugees shared stories of abuse and extortion in Libya, where some people Al Jazeera spoke to spent almost five years.
Medics reported seeing cases of electrocution, wounds by knives and machetes, gunshot wounds and people beaten with rubber and metal pipes.
"You don't see the waves. You just see a boat. And that's your chance to get your freedom again, far away from Libya," said Saou, from the Central African Republic.
The IOM estimates that 10 percent of the migrants present in Libya are women.
"Migrants smuggled into Libya reported severe human rights violations and risks that included rape and amounted to deaths during these journeys," the organisation told Al Jazeera.
Kelly, 32, boarded a flimsy rubber boat to flee Libya while she was eight months pregnant with twins.
"I didn't want to get into the water. It was too risky. I thought the journey wouldn't finish and I'd die," she said after being rescued in November.
There are almost 45,000 child migrants currently in Libya, more than a quarter of whom are unaccompanied.
Some adult migrants are forced to leave their children behind when leaving their country of origin.
Some female migrants are raped during their journeys and give birth en route to Libya or once they arrive there.
Being rescued by an NGO vessel takes these people closer to their dream of reaching Europe.
While the journey is not complete and asylum in Europe is not guaranteed, they say that after being rescued, they feel the safest they have felt since leaving home.
"If the Libyans [coastguards] come on board right now, I will smash my head into the wall, slit my throat and jump into the water. That will be so much better than going back to Libya," Florent, from Cameroon, said.
"Being able to sleep without fear of being woken up by gunshots or being kidnapped for ransom time and again is a blessing," one of the rescued migrants said.
Others said it was a huge relief to get warm meals, to be able to clean themselves and have people to talk to.
"I started to cry when the rescuers told us they weren't from Libya. I couldn't believe that I was going to be rescued and not going to die in the sea."
Despite their traumatic experiences and arduous journeys on land and sea, the refugees and migrants remained hopeful of their pain transforming to joy once they reach the "safety of Europe" and are able to provide for their families back home.
"My father is dead, my mother is dead. It's just me and my wife and I left Nigeria because I didn't have anyone or anything left anymore," said Sondy, 37.
For the rescuers, especially those who have seen a rescue situation change from stable to deadly in a matter of seconds, the job is not easy.
Rough seas, testing conditions, and the urgency and unpredictability of the situation make it difficult.
"We are rescuing people because they have a right to be rescued," said Dragos, a rescuer from Romania.
"If you find a horse or a cow in the water, you will rescue them because they are not supposed to be there."
Leaving on a boat, most of the refugees and migrants do not know how far it is to Italy from Libya.
Some are told by the human smugglers that it is only a small river they have to cross, the smugglers pointing to lights on offshore oil rigs - just over 100km (62 miles) away - and saying that is their destination.
Here, rescued people talk about the countries in Europe they heard about and how the distance to Europe seems very small but the journey very long.
"When I was a firefighter or rescue soldier, nobody questioned my mandate. Now that I'm still saving lives, the work is questioned and even criminalised. I'm just a f****** rescuer trying to save lives," said Tanguy.
Rescuers talked about their constant high levels of stress and their fear that a rubber boat may fall apart in front of their eyes.
"We deal with some very traumatic experiences at sea. And that leaves a mark," said Nicholas Romaniuk, a search-and-rescue coordinator.
Rescued female migrants told tales of physical and sexual abuse that began even as they were setting out from their home countries.
On their way to Libya, many were tortured and raped.
After arriving in Libya, they found physical and sexual violence everywhere: on the streets and during their forced work as cleaners.
Some women said their genitals had been burned.
As the rescued people prepare to disembark in Europe, they realise stern tests await them in front of immigration officials and that their journey is not over.
More than 5,000 migrants were forcibly repatriated by Italy in 2019.
For those who are returned, the violence, torture and extortion they endured on their journey was for nothing.

Aeolus: Weather forecasts start using space laser data

Profiling the world's winds
Aeolus winds now in daily weather forecasts

From BBC by Jonathan Amos 

Europe's novel wind-measuring satellite, Aeolus, has reached a key milestone in its mission.

The space laser's data is now being used in operational weather forecasts.

Aeolus monitors the wind by firing an ultraviolet beam down into the atmosphere and catching the light's reflection as it scatters off molecules and particles carried along in the air.

The European Centre for Medium-Range Weather Forecasts says the information is now robust enough for routine use.

The Reading, UK-based organisation is ingesting the data into its numerical models that look from one to several days ahead.

Forecast improvements are most apparent for the tropics and the Southern Hemisphere.

Meteorologists are constantly trying to increase their skill level; they want to see a certain performance being achieved further and further into the future.

And on one important measure - the eight-day look-ahead - the ECMWF says the Aeolus data enables conditions in the Southern Hemisphere to be forecast with the same level of accuracy an additional 3.7 hours into the future.

"This is just one experimental instrument but it suggests that if you had many more of them in space you would have an even greater impact," the centre's Dr Michael Rennie commented.
"Aeolus shows us there is a lot of promise from this type of direct wind measurement," he told BBC News.

The UK Met Office is likely to start ingesting Aeolus data routinely into its forecast models from the Summer. Meteo France and DWD (Germany) are expected to follow too.
The Americans have also been running simulations to assess the benefits, and the Japanese are about to start.
The Chinese have investigated the quality of the data through comparison with other satellite wind observations.

The European Space Agency's Aeolus satellite is regarded as a breakthrough concept.
Wind measurements have traditionally been very patchy.
You can get data from anemometers, weather balloons and aeroplanes - and even from satellites that infer air movements from the way clouds track across the sky or from how rough the sea surface appears at different locations.

But these are all limited indications that tell us what is happening in particular places or at particular heights.
Aeolus on the other hand gathers its wind data across the entire Earth, from the ground to the stratosphere (30km) above thick clouds.

The Aeolus satellite was assembled from European components in the UK factory of Airbus

How to measure the wind from space
  • Aeolus fires an ultraviolet laser through the atmosphere and measures the return signal using a large telescope
  • The light beam gets scattered back off air molecules and small particles moving in the wind at different altitudes
  • Meteorologists will adjust their numerical models to match the information gathered by the satellite, improving accuracy
  • The biggest impacts are expected in medium-range forecasts - those that look at weather conditions a few days hence
  • Aeolus is only a demonstration mission but it should blaze the trail for future operational weather satellites that use lasers
It's been a challenge getting the technology to work.
For a long time, Europe's engineers struggled to find a design for the UV laser instrument that would work in space.
And when the satellite finally launched to orbit in 2018, it did so 19 years after first approval.

So to see Aeolus working - and working well - is an enormous fillip to all the teams involved in the project's development.

It was, however, built as a one-off research mission and if the forecast benefits are to be maintained, Europe will have to consider a follow-on.

Those discussions have already started.
At a meeting in Seville, Spain, in November, research ministers from the nations that make up the European Space Agency agreed to fund feasibility studies.

It's been suggested that two or three lasers might be flown in a constellation.
"Some of Esa's member states support starting preparatory activities for a potential follow-on mission," said Aeolus mission scientist, Dr Anne Grete Straume.
"Of course, we'd need to improve it and for the next generation there are a number of things we could make even better, such as the stability of the laser instrument. At the moment it looks good but for the future it would have to be absolutely solid," she told BBC News.

Old maps of China shed light on modern border disputes and how it sees the world today at Hong Kong exhibition

From South China Morning Post by Stuart Heaver
  • A show of 80 historic maps and charts reveal China’s view of itself over the centuries and give clues on why the country now conducts business as it does
  • The exhibition at the Hong Kong Maritime Museum also shows that the West’s view of China was long distorted
Towering at a height of four metres, the Huang-Ming Yitong Da Tu, a magnificent old map of China, was hand-copied from an original produced by Japanese monks in Nagasaki in 1771.

The map, whose title translates as the Unified Atlas of the August Ming, is one of 80 historic maps and nautical charts on display at the Hong Kong Maritime Museum as part of an exhibition called “The World on Paper: From Square to Sphericity”.

“Maps both reflect history and are a record of history,” says collector Tam Kwong-lim, who helped curate the exhibition.

Running until February 24, the exhibition not only follows the evolution of Chinese navigation and cartography, but reveals how China saw itself in the world and how the rest of the world perceived China.

Tam bought his first old map of China in a second-hand bookshop in Tokyo while working in the city as a shipping executive in the 1970s.
He has since been an avid collector and is now recognised as an authority on antique maps and charts, which, he points out, still influence modern geopolitical and territorial disputes.
He points to a 1951 Japanese chart showing the South China Sea that is clearly marked in red ink as “China”.
Another Japanese chart, produced in 1943 and including the Philippines, shows a thick boundary line drawn around the
hotly disputed Spratly Islands, excluding them from control of the Philippines, which was occupied by the Japanese at the time.

Museum director Richard Wesley says the old maps help shed light on how the modern Chinese state goes about its business.
“China is now recognised as a global economic superpower, but to better understand the Chinese approach to international trade and diplomacy, it can be helpful to examine how they saw the world and how they mapped it,” he says.

Although China had been producing maps since the Han dynasty (206BC-AD220), there was no attempt to accurately chart its national boundaries or undertake scientific surveys of its territory, Tam says.
It didn’t need to.

Traditional Chinese thinking was greatly influenced by the concept of a “canopy heaven” represented by a spherical heaven and flat Earth.
Everything inside China was ruled over by the emperor.
Everything outside that empire was the world of barbarians and hardly worth bothering about.

Even as trade routes to the Arabian Peninsula developed in the Song dynasty (960-1279), this self-centric view of China at the centre of the heavenly universe remained firmly in place.
Early maps of China had more of a municipal function, showing settlements, roads and geographical features, often with great artistic flourish.

“The maps were drawn like Chinese paintings, depicting rivers and mountains – what was important was the distribution of cities and centres of population density, because they had more of an administrative purpose than a navigational purpose,” Tam says.

Close-up of John Speed’s map, which shows a tall, white-bearded gentleman wearing a red monk’s robe and a large brown wide-brimmed cowboy hat described as a “Chinean” – revealing the paucity of information about China in the late 17th century.

The exception was maritime charts, which were needed to guide Chinese junks safely between ports.
One exhibition highlight is a beautiful nautical chart thought to represent the sixth voyage of the Chinese fleet of imperial treasure junks, commanded by Zheng He.
The Muslim admiral led seven diplomatic expeditions from China’s eastern city of Nanjing to the coast of east Africa between 1405 and 1433.
Though the chart depicts islands, harbours, navigational hazards and sailing routes, it was actually compiled some 200 years after Zheng He’s famous voyages were completed.

The expeditions described in the chart represented a high point in terms of official Chinese engagement with the barbarian world, though Tam notes that Zheng was not the first to sail between China and the Persian Gulf and eastern Africa.
Numerous sailors and merchants had been doing this since the eighth century – possibly earlier.

While Chinese junk captains traditionally hugged the coast, it was their Arab counterparts who held the key to celestial navigation – using the stars and planets to determine position and heading.
It is likely that Zheng employed experienced Arab mariners as pilots and that much of the information on the chart was derived from Arab sources.

Zheng is often cited as the historical symbol of the Maritime Silk Road, which is the inspiration for Chinese President Xi Jinping’s “belt and road” trade and diplomatic initiative.
However, the ancient chart suggests that China could not have navigated very far along the Maritime Silk Road without Islamic knowledge and technology.

It was the arrival of Western technology and knowledge introduced by European missionaries that persuaded the Qing dynasty (1644-1912) to undertake large-scale, detailed surveys of its recently expanded Chinese territory.

In 1708, the 47th year of the Kangxi reign, a team of Jesuit missionaries and scholars were recruited to undertake a comprehensive and highly ambitious cartographic survey of China and the surrounding region.
The map, which is called Huang Yu Quan Lan Tu (Kangxi Imperial Atlas of China), took more than 10 years to complete and covered all Chinese territory plus Tibet and the Korean peninsula.

According to Professor Mario Cams at the University of Macau, at the time this map was produced the Qing empire was almost at the height of its territorial reach.
It had conquered much of the vast Mongolian steppes and parts of Taiwan.
Qing China was sending armies into Tibet and towards the deserts in the far west – today’s Xinjiang region – and laying the foundations for the territory of the modern People’s Republic of China.

The 41 sheets of the copperplate atlas together constitute one large map of continental East Asia, from Lake Baikal (north) to Sakhalin (northeast) and Taiwan (east), and from Hainan Island (south) to Kashgar (west).
It has sometimes been called the “Jesuit map of China”, but Cams says that title underestimates the contribution of Chinese officials and scholars.

This enormous atlas of Qing China, printed in several versions, resulted in the largest mapping project of the early modern world and is unique in a number of ways, Cams says.
First, it was largely based on field surveys conducted by mixed teams of Qing officials and European missionaries.
Second, it is probably the most important example of early modern state-sponsored cartography.
Third, it is a product of the creative integration of two different cartographic practices, European and East Asian.

It was not until 1899 that China produced its first modern map without Western help and referenced to latitude and longitude with a conical projection, according to Tam, but the central meridian remained in Beijing.
Called the Daqing Huangyu Quan Tu (Imperial Atlas of China), the map is remarkable because the external land boundaries are deliberately left ambiguous, Tam says.

“So many Western powers wanted a slice of China [by this time] that they could not define their own boundaries because, diplomatically, China could not afford to upset any third-party power,” says Tam, standing by the 1909 edition of the map on display at the exhibition, which still has the purchase price of 1.20 Chinese dollars displayed in the bottom corner.

In less than a century, China had regressed from an empire under heaven, so self-confident that it did not feel the need to define its boundaries, to a nation that could not afford to define them for fear of upsetting aggressive foreign powers.
Tam says this was part of the process of the “100 years of humiliation” that still informs contemporary foreign policy in Beijing.
“I think it must influence modern Chinese diplomacy,” Tam says, adding that it may be one reason Beijing is still so sensitive about issues of sovereignty.

The first Chinese map with a complete border was not completed until 1905, as part of the self-strengthening movement to modernise and industrialise China to compete with Western hegemony.
Tam describes it as China’s “joining point with modernity”.

It is also apparent that while China needed Western and Islamic technology to inform its traditional view of the world, the Western view of China was distorted and inaccurate until relatively recently.

China is featured in Abraham Ortelius’ Theatrum Orbis Terrarum, published in 1570 and thought to be the first true modern atlas.
Many places in China are marked on this map, but the landscape is shown as a rectangle and some coastlines are wrongly drawn.

Meanwhile, a map of Asia by English historian and cartographer John Speed published in 1676 includes depictions of indigenous people from major countries in the region.
A tall, white-bearded gentleman wearing a red monk’s robe and a large brown wide-brimmed cowboy hat is described as a “Chinean” and reveals the paucity of information about China in the late 17th century.

“Maps and charts offer a new dimension and angle on Chinese history,” Tam says.

Flashback in maritime history – the Afrique passenger ship sinking with 575 fatalities, one century ago



The Afrique was a passenger ship of the French shipping company Compagnie des Chargeurs RĂ©unis, which from 1908 to 1920, traded between French territories of French West Africa, French Equatorial Africa, and Post of Bordeaux in the French colonies.

On her way in heavy seas, the Afrique sprung a leak, presumably from hitting a submerged object.

On the 11th, while 65 miles west from Royan, her engine room got flooded and the boilers extinguished.
She asked for a tow, but not one vessel was able to reach her.
On January 12, 1920, the generators in engine room failed during a storm off the French coast.
The steamers, were then unable to maneuver and was thrown against a reef.
At 23h00, the Afrique hit the Rochebonne Lightvessel and subsequently sank at 3:00, May 12th, of the 609 passengers and crew of whom 15 missionaries and 190 senegalese gunners, only 34 survived.

The disaster is one of the largest disasters in French history, but would be consumed in the shadow of the First World War and presidential elections the same year.
