Investigation: People of no nation: how being stateless means living without rights

This is the third of a three-part investigation I co-reported and co-wrote with María Álvarez del Vayo, Ter Garcia, Carmen Torrecillas, and Adrián Maqueda of Civio with help from some EDJNet partners. Part 1, “Investigation: One small step for a few, one giant leap for the rest: how to become a European citizenis here. Part 2, “Stranger in a native landis here.

Imagine not being able to sign a work contract or not being able to access social or even health services. Forget travelling, enrolling in university or getting married. That is the reality for thousands of people not recognised as nationals by any state. “They have no rights,” says Nina Murray, head of policy and research at the European Statelessness Network (ENS) a London, United Kingdom-based network of civil society organisations.

Many stateless people, Murray explains, come from states that have disappeared. Or they have been displaced from their homes by war or for other reasons. Others have no nationality, because of gaps in the laws of their country of birth: they may be the children of stateless persons or of people whose countries do not recognise as citizens the children born to their citizens abroad. Some people are stateless because the country where they live does not recognise their country of origin as a state, as in much of the European Union (EU) for people from Palestine or Western Sahara.

Investigation: Stranger in a native land

This is the second of a three-part investigation I co-reported and co-wrote with María Álvarez del Vayo, Ter Garcia, Carmen Torrecillas, and Adrián Maqueda of Civio with help from some EDJNet partners. Part 1, “Investigation: One small step for a few, one giant leap for the rest: how to become a European citizenis here. Part 3 “People of no nation: how being stateless means living without rights” is here. The data visualizations are only visible at the Civio website. También hay una versión en español.

Faussan was born in 2016 at Moncloa University Hospital in Madrid, Spain. By then, nine years had passed since his parents left Bangladesh to live in Spain. “When he was born, we registered him and gave him a Bangladeshi passport, because he was not Spanish, he was Bangladeshi,” explains his father, Hassan. When Faussan was one year old, his parents applied for Spanish nationality on his behalf. Despite being born in Spain in 2016, it was not until 2020, four years later, that Faussan finally became a Spanish citizen.

If Faussan had been born in another European Union (EU) country, his early life might have been different. In Germany, Portugal and Ireland he would have acquired citizenship automatically at birth. That is because, though citizenship isn’t granted automatically to everyone born in these countries, it is available to children of people legally residing there for specified periods. As with any other baby born in the country to citizens, Faussan’s parents would have gone to the registry to register his birth as a citizen, they would not have had to apply for a residence permit for him, and the child would never have appeared on Spain’s list of naturalisations because he would have been a citizen from birth.

Magali Varela de Torres, who moved from Venezuela to Madrid, Spain, in 2017, is the only member of her nuclear family who is not yet Spanish. Her husband was Spanish and now her daughter, son and granddaughter are Spanish, too. Varela de Torres, a retired social worker who has official recognition of disability due to her Alzheimer’s, has lived in Spain long enough to apply for citizenship, too. But Spain’s Ministry of Justice has not processed her requests for a health exemption from the culture test required for naturalisation. Her daughter Adriana Torres has submitted three requests over the last three years and keeps getting the same robotic reply from the ministry asking for information she has already submitted. After listening to her daughter tell the story, Varela de Torres says, “It’s as if I don’t exist.”

How Lightning Flashes Help Predict Storms

Counting seconds between a lightning flash and thunderclap is how anyone can tell how far away a thunderstorm is. (The storm is one kilometer away for each three seconds you count.) But if you want to know when the storm is coming and how strong it will be, you’re better off counting lightning flashes. That’s because supercomputer-armed meteorologists can use lightning-flash data to make more sophisticated predictions.

A team led by meteorologist Ming Xue at the University of Oklahoma reported last month a new way to incorporate lightning data into thunderstorm-forecasting models in Advances in Atmospheric Sciences. Early efforts to use lightning flashes were centered on regional ground-based networks of lightning detectors. In 2016, the U.S. National Oceanic and Atmospheric Administration (NOAA) launched the Geostationary Operational Environmental Satellite (GOES)-16 and -17 satellites with cameras designed to detect lightning flashes, making it possible to watch how lightning evolved over most of both American continents.

The satellite-mounted devices, called Geostationary Lightning Mappers (GLMs), offered the potential both of better understanding the relationship between lightning and thunderstorms, and the possibility of using the lightning data to improve thunderstorm forecasts. Indeed, in one early use, forecasters predicted that a threatening storm would move away from an outdoor concert, preventing an unnecessary evacuation.

“This study and its direct predecessors are the only ones I’m aware of that take advantage of GLM’s method of lightning observation through use of the Flash Extent Density measurement,” says assimilation researcher Amanda Back of NOAA. “Because the GLM is an array of optical sensors, it records not just pointlike lightning locations, but also the horizontal extent of the lightning detections.”

Yet, incorporating that data into weather-forecasting models fast enough to improve storm forecasting is an enormous computing challenge. Meteorologists use various different frameworks to assign different weights and uncertainties to each available data sources and input the data into computer models of the atmosphere that then generate storm forecasts. 

Since the satellite-based data is so much more extensive than previous regional datasets, researchers are trying to find more efficient ways to direct the flood of lightning-flash data into NOAA’s supercomputers.

Xue and colleagues, who had previously used a framework called a Gridpoint Statistical Interpolation ensemble Kalman filter (GSI-EnKF) to feed lightning data to forecasting models, decided to test a different approach, called a GSI ensemble-variational (EnVar) hybrid data-assimilation framework. The GSI EnVar approach is different because it incorporates information about the covariance of certain variables in models whose predictions it compares. The new method also makes it possible to fill gaps where the models share an error with what’s called a static covariant component.

However, running so many calculations requires trade-offs elsewhere, whether in how the team simplifies the physics of storms in their model or how they combine uncertainties and other parameters.

In the best case, their approach would provide better forecasts with a lower computing cost. Even matching the other model’s forecasts with lower computing costs would free up weather computers to incorporate other sources of data, which is a win, too.

The team decided to test their new framework against a well-studied storm that took place in Kansas and southern Nebraska on 1 May 2018. When the team compared their new framework, with the addition of the new two-dimensional satellite lightning data, to a framework designed to accommodate ground-based radar data, which is three-dimensional and generally requires more computing power, they found the new framework was faster despite the additional data.

The team found that their new approach matched the accuracy of previous frameworks, with the advantage that it includes the satellite lightning data, and at little to no computational cost. However, the team notes that they used a simplified relationship between lightning and the freezing raindrops in a storm, which are called graupel. If they or another group can accommodate the more complicated relationship meteorologists know exists there, they may be able to build an even better forecast.

They will also need to test their system against different weather systems, says Back: “It will be interesting to see how robust the method is when applied to a very different regime, for example, a hurricane. Will further calibration be needed?”

“I think it’s a good start for getting the real lightning data into NOAA’s models,” says lightning scientist Daile Zhang at the University of Maryland.

UPDATE 16 January 2024: The story was updated to include new information both about Geostationary Lightning Mappers and the testing protocols that the researchers developed to refine their forecasting models.
