When the Iron Curtain fell 15 years ago, the free world's scientists got their first good look at the environmental consequences of East Europe's communist economy.
Scientists worldwide have since been studying the region's polluted sites and helping post-communist governments launch massive cleanups of old Soviet military bases, Czech uranium mines and Slovakian chemical plants.
Now, the same scientists are turning their attention to a new and apparently larger environmental challenge -- China.
A window to China's problems with land and water contamination is slowly opening to the rest of the world's environmental experts. As a result European scientists, including some from former communist countries, are getting involved.
Czech plant biotechnology specialist Tomas Vanek, who was recently invited by Beijing authorities to work on soil contamination issues, says: "Now China is starting to cooperate."
An international conference in Nanjing last autumn reflected what appears to be China's growing willingness to accept foreign expertise.
British, Dutch and Czech scientists were among those welcomed to the Soil Pollution and Remediation Conference, sponsored by the Chinese Academy of Sciences and other government agencies.
They focused on ways to remedy environmental problems created by China's ongoing rush to industrialize, modernize farms and expand cities.
Vanek presented a paper on the use of flax and hemp crops to remediate land contaminated by low-level radioactivity.
According to his five-year study, flax can be safely grown in radioactive soil and then harvested for industrial purposes, such as fibres and non-edible oils. Both crops also prevent erosion and provide revenue to offset the costs of managing waste sites.
Similar studies on so-called "phytoremediation" techniques are being conducted around the world.
Swedish scientists are now testing Vanek's idea to grow hemp on polluted land and process the harvested crop for auto insulation, rope or as an energy source.
Vanek said Chinese officials "are very interested" in phytoremediation as a low-cost solution to land pollution.
How much land in the world's largest country will require an environmental cleanup?
"No one really knows," Vanek says. "This data is partially confidential."
Papers presented by Chinese scientists at the conference confirmed Vanek's point. One by four experts from the science academy and a Nanjing university said the amount of soil pollution nationwide is "unclear."
The Chinese experts cited a 1999 Beijing government report which said "various contaminants" had polluted 20 percent of the nation's cropland, while "another report indicated that about 20 million hectares of the cropland was contaminated with heavy metals and about 60 million hectares of cropland was polluted with pesticides and other chemicals."
Other Chinese scientists at the gathering emphasized a need for more basic research, environmental standards and government regulations to clean up polluted land as well as prevent contamination.
A key impetus for giving the environment more attention, the scientists said, was foreign investment.
Multinational companies that have expanded, or may expand, into China often carry their own land use standards which, for example, prevent them from building factories on heavily polluted ground.
One study at the conference described the complicated process of testing and then remediating polluted groundwater at a site in northern China where a company wanted to build an auto factory. The water had been contaminated by chemicals leaking from a former lumber yard.
European scientists like Vanek are offering their Chinese colleagues research findings as well as important information based on personal experience.
One study presented by Swiss and Bulgarian scientists, for example, examined problems near Sofia where farmland was contaminated by metals from industrial smelters. Similarly a British study looked at using plants to clean up sites tainted by explosives.
Vanek says recent Czech experience with cleaning up old uranium mines, which supplied material for Soviet warheads and nuclear plants, helped underscore the advantages of flax as a money-making cover crop in radioactive areas.
Now Vanek is working through e-mails with Chinese scientists who face similar issues and, finally, are allowed to talk about it openly with experts around the world.
In an article published on this page on Tuesday, Kaohsiung-based journalist Julien Oeuillet wrote that “legions of people worldwide would care if a disaster occurred in South Korea or Japan, but the same people would not bat an eyelid if Taiwan disappeared.” That is quite a statement. We are constantly reading about the importance of Taiwan Semiconductor Manufacturing Co (TSMC), hailed in Taiwan as the nation’s “silicon shield” protecting it from hostile foreign forces such as the Chinese Communist Party (CCP), and so crucial to the global supply chain for semiconductors that its loss would cost the global economy US$1
Concerns that the US might abandon Taiwan are often overstated. While US President Donald Trump’s handling of Ukraine raised unease in Taiwan, it is crucial to recognize that Taiwan is not Ukraine. Under Trump, the US views Ukraine largely as a European problem, whereas the Indo-Pacific region remains its primary geopolitical focus. Taipei holds immense strategic value for Washington and is unlikely to be treated as a bargaining chip in US-China relations. Trump’s vision of “making America great again” would be directly undermined by any move to abandon Taiwan. Despite the rhetoric of “America First,” the Trump administration understands the necessity of
US President Donald Trump’s challenge to domestic American economic-political priorities, and abroad to the global balance of power, are not a threat to the security of Taiwan. Trump’s success can go far to contain the real threat — the Chinese Communist Party’s (CCP) surge to hegemony — while offering expanded defensive opportunities for Taiwan. In a stunning affirmation of the CCP policy of “forceful reunification,” an obscene euphemism for the invasion of Taiwan and the destruction of its democracy, on March 13, 2024, the People’s Liberation Army’s (PLA) used Chinese social media platforms to show the first-time linkage of three new
Sasha B. Chhabra’s column (“Michelle Yeoh should no longer be welcome,” March 26, page 8) lamented an Instagram post by renowned actress Michelle Yeoh (楊紫瓊) about her recent visit to “Taipei, China.” It is Chhabra’s opinion that, in response to parroting Beijing’s propaganda about the status of Taiwan, Yeoh should be banned from entering this nation and her films cut off from funding by government-backed agencies, as well as disqualified from competing in the Golden Horse Awards. She and other celebrities, he wrote, must be made to understand “that there are consequences for their actions if they become political pawns of
