Data Journalism Top 10: China’s Vast Fishing Fleet, Europe’s Internet Speed, Afghan Resources, and US Murders Rate

Read this article in

With the United Nations Climate Change Conference (COP26) coming up in a month in Glasgow, Scotland, global warming and environmental damage have been on the main agenda for news organizations around the world. Tracking the most popular data journalism stories on Twitter from September 20 to September 26, using NodeXL mapping and our own human curation, we also found investigations into burning oil in the Greek islands, heat-related deaths in Germany, China’s vast fishing fleet, the US murder rate, and anomalies in the recent Russian election.

China’s Sea Power

Last year, satellite data showed several hundred Chinese ships fishing for squid near Ecuador’s Galapagos archipelago, a UNESCO world heritage site. The discovery prompted more debate about the threat of overfishing, especially in an area home to giant tortoises, hammerhead sharks, and other endangered species. To observe the Chinese fleet, the Associated Press and Spanish-language broadcaster Univision spent 18 days on the high seas earlier this year. Journalists analyzed more satellite and fishing data to examine the environmental impact of China’s sea operations.

Border Refugees

Migration continues to be a major issue for US authorities despite the Biden administration’s move to undo hardline policies by his predecessor, former President Donald Trump. One public health policy, which Biden hasn’t reversed, allows authorities to deny migrants a chance to claim asylum, and fly them back to their homeland. Reuters analyzed data by the US Customs and Border Protection agency to investigate how many migrants have been expelled under the so-called Title 42 public health policy.

Burning Oil

Last year, Greek GIJN member Reporters United joined with Investigate Europe to publish an investigation that shows how the European Union has sabotaged its own climate goals with massive fossil fuel subsidies. In a follow-up to that project, the team focused on the Greek islands, which are cut off from the country’s main power grid, and need to rely on oil generators that cost billions of euros to run.

Internet Speed in Europe

If you live in a European city, chances are you enjoy robust internet speed. An analysis by Osservatorio Balcani Caucaso Transeuropa, published by the European Data Journalism Network, found that internet performance has improved significantly over the past 18 months. But reporters also found that the gap between urban and more rural areas has increased, too. This type of regional inequality can seriously affect business, education, and other areas of social life.

Afghanistan’s Mineral Resources

In 2019, Afghanistan’s Ministry of Mines and Petroleum published a report revealing what many analysts have long suspected: that the desperately poor nation holds as much as $1 trillion-worth of untapped mineral resources. But investors and experts told Al Jazeera that poor security, weak legislation, and corruption have prevented the development of the mining sector. Now that the Taliban has taken control of the war-torn country, the outlet’s graphics team produced this visual piece to illustrate the scale of the reserves and their geographical location.

US Murder Rate

In 2020, the US saw the biggest rise in murders since the start of national record-keeping in 1960, The New York Times reported. Data collected by the FBI shows that — although the murder rate stands far below its historic peak in the 1980s — almost 5,000 more murders were committed last year compared to 2019, for a total of around 21,500. In around 77% of the cases, the perpetrator used a firearm. The Times’ Upshot team dove into the numbers, noting that the change in murder is “a national phenomenon and not a regional one.”

Water Deficit

Palestinian families have suffered from severe water shortages for decades. When they don’t have enough water to supply their needs, some are forced to buy it from an Israeli company, Mekorot. Some cities on the West Bank are now dependent on Mekorot as their main source of water, according to an investigation by GIJN member Arab Reporters for Investigative Journalism (ARIJ). These water shortages have also prompted some Palestinians to buy allegedly contaminated mineral water from another Israeli company.

German Heat Islands

Thousands of people are dying in Germany each year from the consequences of heat. Urbanization and rising temperatures due to climate change are exacerbating the problem. Bavarian Radio (BR) examined satellite images to illustrate so-called “heat islands,” which show German cities that are particularly hot.

Russian Election Anomalies

After President Vladimir Putin’s party United Russia won the recent elections to the State Duma in Russia, journalists and independent analysts expressed concerns about possible vote fraud. The claims are partly based on mathematical laws that usually impact turnout and voting results. While examining this data, iStories has detected some suspicious anomalies.

UK Benefits Challenges

In England, Scotland, and Wales, seven of every 10 appeals over rejected disability benefits were successful since 2018, according to an analysis by the BBC Shared Data Unit. In Northern Ireland, six out of 10 appeals over the past two years prevailed. But in the same period, hundreds of people suffering from disease or other maladies have died before having the chance to hear judges rule on their case.
