Nearly one out of three people in Beijing belongs to the mobile population, according to the capital's population and family planning commission.Workers stand on a temporary dormitory at the Central Business District in Beijing September 2, 2007. China's 120 million migrant workers, the young generation in particular, are demanding higher wages and a better working environment, the Labour Ministry said. [Agencies]The municipality's mobile population reached 5.4 million in October, accounting for nearly 30 percent of the total, the commission's deputy director Li Yunli said.More than 80 percent of the capital's mobile population belongs to the China-unique category of rural migrant workers, Li told a conference on population in Beijing on Monday. The remainder is mostly made up of people visiting for less than a month.She added that migrant workers would comprise the vast majority of both the capital's and the nation's mobile population for a long time to come. Currently, the national mobile population stands at 150 million.The most recent influx of migrant workers boosted the capital's population to about 17.4 million by October, signaling Beijing's population would likely exceed its threshold of 18 million earlier than previous forecasts, Li said.The total population would continue to grow in Beijing over the next five or 10 years, Li said, and "that would further strain scarce resources, including land, water and energy".Previous research has suggested that accommodating more than 14 million residents would exceed Beijing's food- and water-supply capacities.More than 130,000 people were born in Beijing in 2007 as of October, and more than one-third of them were born to migrant families, Li said. And according to her, there would be even more births next year.This year, most of the capital's unplanned births were to migrant families, Li said."Family planning among migrant workers is crucial to China's overall family planning, and the construction of a new socialist countryside and a harmonious society," deputy director of the State Population and Family Planning Commission Wang Guoqing was quoted as saying by Xinhua news agency earlier.In addition, most of the migrant workers in Beijing work labor-intensive jobs in fields such as manufacturing, home furnishing, catering, cleaning and domestic services.Most migrant workers received little education, with 60 percent of them dropping out after junior middle school mainly because of financial problems, Li explained.More than half of them earn less than 1,200 yuan (0) per month and live in poorly equipped rental rooms, Li added.Researcher with China Foundation for International and Strategic Studies Qin Xiaoying said that if migrant workers remain economically and socially marginalized, mental anguish could flourish among the demographic and threaten social stability.The commission urged governments at all levels to improve public services for the migrant population, protect their legal rights and interests, and reduce discrimination against them.

CHANGSHA -- Central China's Hunan Province said it has taken effective measures to prevent epidemics after about 2 billion rats chomped their way through cropland around the Dongting Lake, the country's second largest freshwater lake. "It's not possible for rodent-borne diseases to break out in the lake area," said Chen Xiaochun, vice director of the provincial health department. Local health authorities have been watching closely over the rodent situation after the rats fled their flooded island homes and invaded 22 counties around the Dongting Lake last week, he told a press conference on Wednesday. Results of their observation are reported daily to the provincial health department and the public, he said. Meanwhile, local health and disease prevention and control authorities have intensified management of raticide and pesticide, for fear they might contaminate food and water, Chen added. No human infection of any rat-borne disease has been reported in the central Chinese province since 1944. The provincial government also ruled out widespread suspicions that rats flooded the area because one of their natural enemies -- snakes -- had been served at dinner tables. "The Dongting Lake area is not an ideal habitat for snakes," said Deng Sanlong, a top forestry official in the province, "and the only two species that inhabitate the region feed largely on fish and frogs." He said the top enemy of the rats are hawks that spend winter in the wetland around the lake but fly away in spring. China's Ministry of Agriculture and the Hunan provincial government have allocated 900,000 yuan in total to eradicate the rats.

SHANGHAI -- China will launch its first Mars probe in October 2009 as part of a joint mission with Russia, said sources with the Shanghai Space Administration, the main developer of the probe, on Monday. Researchers are "pressing ahead" with the project for a synchronized launching with a Russian probe, said Chen Changya, a researcher with the Shanghai Institute of Satellite Engineering, at a space technology exhibition. He said the home-developed Chinese probe is scheduled for completion by June 2009. The probe, 75 centimeters long, 75 centimeters wide, 60 centimeters high and weighing 110 kilograms, is designed to be able to serve a two-year mission, according to Chen. Its model is on display at the exhibition. The Chinese probe, with Russia's Phobos-Grunt, will be launched by a Russian carrier rocket, Chen said. They are expected to land on Mars in 2010 after 10 month's flight.

BEIJING  -- The dumpling poisoning incident in Japan has been proved to be an individual contrived case, not caused by pesticide residue, said China's quality watchdog on Thursday.The General Administration of Quality Supervision, Inspection and Quarantine (AQSIQ) said at a press conference that it made the conclusion after finding no harmful chemicals in relative products and samples and no abnormal operations by the Chinese producer.Japanese media reported on January 10 that people fell ill in December and January after consuming frozen meat dumplings produced by Tianyang Food Plant based in north china's Hebei Province.

XINTAI, Shandong -- Fifty million yuan (US.6 million) has been donated for miners from the two flooded collieries and their families in east China's Shandong Province by Sunday noon, according to local sources.The money shall be used for rescue work, consolation for relatives of the trapped miners, and subsidy for other miners as operation of the mines is suspended.Among the donators, the China National Coal Group Corp. was the first to offer a large amount -- one million yuan (US1,578.9). Following suit was the the adjacent Xinwen Coal mine that donated 3.2 million yuan (US1,052.6).After the accident, governments of Jinan and Qingdao, two big cities in Shandong, each donated three million yuan (US4,736.8); Jining and Laiwu, the neighboring cities of Xintai, provided two million yuan (US3,157.9) and one million yuan respectively.Individuals were also involved in the nationwide effort, among whom was Gao Runze, who donated 20,000 yuan and 10 tons of disinfectors worth about 30,000 yuan. Gao had been trapped in a flooded coal mine 58 years ago and was rescued with 30 fellows.A garbage collector Li Quan who lives in the Huanyuan residential quarter donated 200 yuan. "Many miners and their relatives helped me a lot in the past," he said, "I don't have much money but this is what I can do."Flood water swept through a 65-meter wide breach in the Wenhe River levee on August 17, inundating the Huayuan and Minggong mines, leaving 181 people trapped underground.Chinese water resources specialists have blamed the disaster largely on heavy rain and inadequate flood prevention facilities.Local government publicized a donation phone number +86 539 7837050, and old miners of Huayuan called on for donations to help miners and their families tide over the disaster.Eight pumps are busy working in the mines, piping out 4,129 cubic meters of water per hour.By 6 pm Sunday, water level in the shaft of Huayuan coal mine has dropped to 61.54 meters, 30.46 meters down from the highest level. But rescuers have to lower the water level by another 91.54 meters to reach the 172 trapped miners.In the nearby Minggong coal mine, water level has lowered to 61.92 meters.Apart from the rescue work, consolation work was also underway for the families of the trapped workers. The tragedy had a heavy blow on the company's community, and one out of every 50 families has someone trapped down the pit.Sixty family members had been hospitalized with high blood pressure or heart problems, said Huangpu Tinghua, deputy general manager of Huayuan Mining Co. Ltd.Earlier at this weekend, the families of 172 miners trapped in it had each received 2,000 yuan (US6). And officials said China would not give up on the 181 trapped miners.
