The cities on the list that one does not expect are cities such as Jodhpur in the Thar desert, and Srinagar in the mountainous region of Kashmir. Srinagar is on the list because of inadequate sewage facilities to treat sewage. The Dal lake is polluted from houseboats and tourist hotels dumping sewage into the lake and not connecting to the sewage system. Jodhpur is polluted from auto exhaust and vehicular pollution.. The WHO says India's efforts to control pollution need to follow the steps taken by China recently. In response to citizen pressure and outrage about health conditions China has closed down polluting factories, and is shifting away from coal, away from coal stoves. India's efforts are inadequate and scattered says the WHO. This includes stopping fireworks sales that aggravated toxic conditions in Delhi. A program giving 37 million poor Indian women free gas connections helps a shift from use of dung fired clay ovens or coal ovens. Pollution kills 7 million people each year says WHO, and over half or 3.8 million people die from use of unhealthy cooking stoves which create indoor air pollution. Of cities above 14 million Delhi ranks first, Cairo, Egypt second, Mumbai, India fourth and Beijing fifth in air pollution levels.  ...

Nature Conservancy reports that trees planted in cities reduce particulate matter by between 7% and 24%.  Particulate matter are microscopic particles we breathe in when there is polluted air from automobiles, factories, or smoking. The cooling effect is about 2 degrees centigrade or 3.6 degrees fahrenheit. Outdoor air pollution causes asthma and other lung diseases, and led to premature deaths of about 3 million people in 2012, according to the World Health Organization (WHO). Hospitalization from high pollution levels is another major problem, especially in poor and middle income nations, such as Brazil, Mexico, India, China and Indonesia. Air Flow should be considered when planting trees in congested urban areas. Cities in the west also benefit from tree planting, and London has benefitted from the park spaces and tree planting.

India is expected to become more urbanized by 2030 with people living in cities growing from 285 million in 2001 census up to 590 milion, producing 70% of national income. This means issues of climate change are not just about the environment- they are development issues and how to find better ways to plan future low-carbon infrastructure from the early stage. Also learning lessons from the chaotic development in China that in the rush for development allowed the air, water and environment to be hugely polluted.

The air quality around Chinese cities is worsening because of coal fired plants and increasing demand for energy, and because of exhaust from automobiles filling the highways. The air quality around Beijing violated the WHO standards more than 80% of the time during the fourth quarter 2008 period. China's Ministry of Environmental Protection says in a report that more than 25% of China's rivers, lakes and streams are too polluted to be used for drinking water. And acid rain is a problem in 200 of 440 cities it has monitored. Efforts to control the exhaust pollution from cars by putting driving restrictions in Beijing are not as effective. One report says that even after 20% of private cars are taken off the road each weekday, the 250,000 new cars that were added to Beijing's streets in the Jan-April 2010 period, have left things as bad as they were before.

Efforts by China's Environment Ministry to control environmental damage after three decades of growth. The ability to control local officials who put growth above any environmental considerations is a key part of the struggle to minimize the damage to China's environment. Local officials are now evaluated by how well they do on environmental protection goals in addition to other goals. Promotions can be blocked by the environment ministry for officials who do poorly on environmental compliance. Vice minister Li Ganjie says the shift of dirty industries from cities to rural areas is leaving the countryside more polluted.

This report in FR24 cites the director of research at France's National Institute of Health and Medical Research, Inserm, about the damaging effects of an insecticide used in the French West Indies. The result is that there are violent protests against the vaccine mandate being implemented in the French West Indies. 

The FR24 report says that about a third of the marine coastline, and a third of agricultural land and land for breeding, in the West Indies islands of Guadeloupe and Martinique is polluted by the insecticide chlordecone. The insecticide was first used in banana plantations in the French West Indies against banana insects. The insecticide has now contaminated the soil and groundwater.

During the period of lockdown there were some positive changes and people are now looking at how some of these positive changes can be preserved. Drastically cut air pollution and the impact on health is one of these positive changes. People with difficulty breathing in the pollutants in the air had symptoms relieved and now dread going back to the pollution levels they had to get used to. For some lockdown has even given them a break from illness. Many people who experienced the clean air and calm of this period of the virus  are now asking how this can be preserved. In cities like Birmingham polluted air is known to reduce lifespans by 7 months for children. In the UK this is particularly true of the Midlands region with its road and air traffic industries, where there is a nostalgia for the calm people had from the experience of living and working from home. The stresses of capitalism and the rush and pace of life being muted for a while, and a bigger focus on the collective wellbeing and the community. In London and other parts of the UK there is the national debate on how one can continue to make the intelligent choices in the way we live and in the tradeoffs between health and wealth.    ...

China's environmental protection ministry's report on what its costing China to have runaway growth- it would cost 136 billion dollars to clean up the environmental damage done by haphazard reckless growth and dumping of chemicals. Meantime about 300 million people suffer from the contamination of water and lack of access to clean water. Of the 25 most polluted cities in the world 16 are in China.

The concentration of particles less than 2.5 microns in diameter reached 700- 886 micrograms per square meter in Beijing in Jan 2013, 500 is routine. The World Health Organization says a level of 25 micrograms per square meter is safe, above 300 poses risks calling for one to stay indoors. This is the high cost of rapid motorization of China and lack of strict pollution control laws and enforcement for industry. The pace of car sales in the last ten years was extremely fast and unprecedented in comparison to Europe, the U.S. and Japan in a similiar period of development.

According to a report from China's Environment Ministry for the first half of 2013, only 4 cities met the acceptable air quality standards. The national grade 2 standard in China is for 35 micrograms per cubic meter for levels of airborne particulate matter smaller than 2.5 micrograms in diameter. WHO standard is for 25 micrograms per cubic meter in a 24 hour period. The 4 cities with acceptable air qualty out of 74 cities monitored by the Environment Ministry are Lhasa in Tibet, island city Haikou, coastal town Zhoushan, and Pearl River Delta city of Huizhou.

The action taken by local and government officials to address the high PM 2.5 pollutant levels and smog in Harbin, China, in October 2013. For the first time the Ministry of Environmental Protection has powers to take serious action. It is sending out inspection teams to cities across China for the winter to make sure environmental regulations are enforced. One big change is that cities now report in real time the change in pollutant levels for PM 2.5, the worst pollutant. By Oct. 2013 113 cities in China carried the live reports on websites. The Ministry has published a list of the 4189 factories in China that create 65% of total industrial air pollutants in China. The Jinping-Li Keqiang administration supports the stronger enforcement and has set a goal of reducing PM 2.5 levels by 15- 25% each year for Tianjin, Beijin and Hebi province in northern China, compared to 2012 levels. These three regions have been given the target of reducing coal use by 80 million tons a year.

China's Environment Ministry has not released the results of a soil survey from across China. Independent estimates from Nanjing Agricultural University in a 2007-2008 survey showed about 10% of rice in China contaminated by high levels of cadmium. In May 2013 officials found a large number of samples of rice from markets in Guangzhou contaminated with cadmium. Cadmium is a carcinogenic metal that damages the kidneys and weakens bones when unknowingly taken in excessive levels.

The Chinese Academy of Environmental Planning, under the Ministry of Environmental Protection, has estimated cost of pollution in a new study of the costs of environmental pollution in China. The cost is estimated at $230 billion for 2010, or 3.5% of GDP, and close to 4 times the cost in 2004, showing the rapid degradation of the environment from rampant industrialization. The first such estimates were made in 2006 and since then come out spradically from the Environment Ministry. For 2004 the Environment Ministry estimated cost of pollution was $62 billion, for 2008 partial cost estimate was $185 billion. Even the $230 billion figure fo 2010 is incomplete say researchers. Only after strong public protests over Beijing's air pollution have government officials allowed candid reporting on environmental costs. Environmental costs extend to food contamination. A report on China Central Television recently said farmers in a village in Henan province used wastewater from a paper mill to grow wheat, which was then sent to cities as farmers in the village grow wheat for their own use from well water. A Deutsche Bank report in Feb 2013 says there will be a continuing decline in the environmental degradation for the next decade under current policies, higher coal consumption and growth in automobiles....

China is closing energy inefficient aging factories. The Chinese government plans to close 76 factories in cement, 279 in paper, 175 in steel, and 84 in leather as part of this effort. This still leaves China with a lot of work to do to acheve the 20% reduction per unit of economic output in 2010 compared to 2005, that its current five year plan calls for. Efficiency went up by 14.4% in the first four years of the current plan, but went down by 3.6% in the first quarter causing serious concern.

There appears to be a conscious deliberate decision by the Chinese government and policymakers to shift the economy from low-end technologically unsophisticated and polluting industry, that pays low wages with little worker protections, towards technologically sophisticated, environment respecting, and higher wage industry. This does not mean textiles are out, but textile companies that are larger better managed, able to introduce newer technologies and produce higher quality product- that command higher prices in the world market and therefore also able to sustain decent wages and worker protection- are in. Phasing out the smaller shops and the poorly run or deliberately polluting and labor exploiting companies run from Hong Kong or elsewhere. The general shift is to be a leader in products which are value added either by technology or human capital, such as better trained more knowledgeable workers. This is similiar to the shift Japan made after the sixties, as it moved from a rural to a urbanized society and textile companies like Kanebo became technologically sophisticated, while small shops withered out, and Japan gradually shifted into automobiles, electronics and chip making. The noticeable difference is that Japan with a prewar industrial base and a smaller market protected its home market for Japanese companies, whereas China lacking this prewar industrial base let foreign investment and companies overseas bring in equipment and use low cost Chinese labor to supply western markets. And it turned a blind eye to labor protections, at least till it had built up its own industrial base and knowhow with policy requiring Chinese partners in industry and technology transfer. Economic winds are also doing the job. Inflation, Chinese goods prices increased by 4.6% in May according to the U.S. Commerce Department. This is a result of the Chinese government requiring worker protections and decent wages and stricter pollution enforcement resulting in increased energy costs. For years the U.S. and other countries depended on China for low cost goods and the demand for low cost goods depressed margins which resulted in legitmate costs such as pollution control technology, worker protection and decent wages, being ignored. China is now left with heavy environmental cleanup costs, and a bad image internationally as a heavy polluter. The huge external trade surpluses China has built up exceeding a trillion dollars have pushed up the value of the yuan making Chinese goods costlier in world markets, and apparel and shoe makers in developed countries seeing Vietnam as a better lowcost alternative. The story of this phase of Chinese industrial development can be seen in a town like Honghe, a 90 minute drive from Shanghai, which has half of its 100,000 residents working in 100 factories and 8000 shops that knit, dye, package and ship some 200 million sweaters a year, bringing in according to local government estimates $650 million a year. Now many of these shops are idle and mirant workers are returning home. To see the subtler signs of the Chinese policymakers hand note that even visa policies have been tightened to make it harder for foreign buyers to visit Chineses factories and trade shows. Also the Chinese government has raised the minimum age for workers in these factories from 16 to age 18 and so on. And the impact is being felt in places like Honghe near Shanghai, Shengzhou another city near Shanghai which makes one third of the world's neckties, and in Dongguan in Guangdong where its toy, shoes shops close. The change also shows how quickly things can change in the world economy. Only 3 years earlier in 2005, Jiaxing Yishangmei Fashion Company, a family owned company was booming and had just landed Walmart Stores as a customer. Now Walmart no longer sources from this company. Analysts say that the Chinese sweater industry was probably overbuilt, with about 6 cities in China claiming to produce more than 100 million sweaters annually. A wave of consolidation could boost efficiency, and bring pressures to innovate rater than compete only on price. And many Chinese economists, and policymakers think China has relied too much on cost-cutting and simple production models to increase exports. A researcher at the Chinese Academy of Social Sciences thinks such a high dependence on foreign trade is not good for China. For the US and Japan this researcher says that trade is equivalent to 20% of gross national product and by contrast for China trade is equivalent to an extreme of 75% of GNP. ...

"Defend blue sky and breathe together" says a painting on a brick wall in the coal producing region of Shanxi, northern China. China is finally acting seriously to impose strict environmental rules from the top. Old coal stoves are thrown into a dump as China shifts away from coal stoves to heat homes. So many new homes shifted to natural gas in Shanxi province. population 37 million, that demand overwhelmed natural gas supplies. Results are to be seen in cleaner air in Taiyuan, capital of the province and in Beijing itself.  President Xi's commitment to climate change accord reached in Paris is seen as firm in this report in the NYT. The head of the gas, coal and power markets division of the International Energy Agency, Mr. Peter Fraser, says that even though homes use only 6% of total coal used in China, the effects are disproportionately high because homes do not have any emission reduction mechanisms. Natural gas demand has increased by 16% in 2017 as provincial officials eager to meet the demands issued in Beijing to cut coal emissions even let some homes and schools go without heat in an early winter spell. This extraordinary report shows how in cities in northeastern China the people welcome the change to natural gas and cleaner air. Even in coal country, in cities like Linfen population 4.4 million, the change is seen as people welcome the clean air and officials build natural gas connections to execute the plans issued in Beijing. In Beijing itself Greenpeace estimates show 54% reduction in PM 2.5, harmful particulate matter for breathing by 54%, a startling fact showing Beijing's determination and effectiveness of its actions. Natural gas is more expensive and citizens do not complain in neighboring provinces near Beijing because the state provides adequate subsidies to compensate people. Decrees are being enforced to avoid coal stove use with people knowing they could see action by authorites if reported. Compare this to the problems of crop burning around New Delhi, in Haryana and Punjab provinces, and one can see that centralized control and direction has advantages when used in the right way for a good purpose and supported by people who want to breathe clean air. ...

An official report after a 7 year survey finds 19.4% of arable land in China is polluted. The pollution comes for the most part from inorganic materials such as heavy metals cadmium, nickel which are byproducts of mining. Pollution is severe in the Pearl River Delta in the south, in Yangtze River Delta in the east, and in older industrial zones in the north east. Earlier efforts to get this data were stymied by some officials calling it a state secret about the time of the discovery of cadmium contaminated rice in Hunan province. China's 334 million acres of arable land, according to the most recent land survey at the end of 2012, is only 37 million acres above the minimum considered necessary to feed the large population, making this a major issue for China.
