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.

Experiment conducted at the Gujarat Electricity Board by researchers from MIT and Harvard on correcting the flaws in the audit process for compliance with pollution control regulations by heavily polluting plants. The experiment is conducted in the state of Gujarat in northwestern India. The heavy polluters faced a audit process where fees were paid out of a central fund, were told plants could be audited for a scond time for false reporting on pollutants emittted, and faced additional disincentives of cut off of electricity supplies for noncompliance in correct reporting. This type of improvement is relevant for pollution control in China, India, Indonesia and other developing countries with similiar reporting issues and non compliance with pollution laws. Noncompliance and cozy relationships with auditors and regulators is a major problem for implementing pollution laws in these countries.

This analysis of coal use using graphs shows a clear move away from coal in the world, except for two growth markets China and India which account for 60% of the increase in coal use since 2008. India has gone black in its shift to increasing use of coal. China has begun the shift away from coal to address the smog over large urban areas, poor air quality and health impact of coal use. Because China used five times the coal used by India in 2017, the overall impact in China and India is showing a shift away from coal to hydropower, other renewables including solar energy. It is likely that India will make the shift following China's example in the future. 

The trend is clear when one looks at the incremental terawatt hour and where it comes from. The shift is clear to renewables, hydropower, and non fossil uses in the rest of the World and China which account for most of the coal use in the world.

The situation in Guangdong province in 2012, with older factories unable to compete with the rising wages, stricter environmental enforcement, and lower export demand. Many Taiwanese manufacturers are closing factories. The growth in Dongguan, a manufacturing hub in Guangdong, is estimated at 3.5% for the first three quarters of 2012, half the overall rate for Guangdong province. A researcher in a Chinese think tank says China's manufacturers are in a kind of "sandwich trap" with competition from Vietnam and India in lower wage production and competition from Germany and the U.S. in higher wage technology intensive products. This is especially true in 2012-2013, now that U.S. and German manufacturers have reduced costs and increased competitiveness.

Two Harvard economists, Lawrence Summers and Lant Pritchett, say China is likely to revert to the mean of average long term growth of developed countries after this spurt of growth is over. Growth is likely to slow to 6% by 2016, and revert to the mean of 2% for industrialized countries in the long term. Goldman Sachs banker Jim O'Neill, says the growth at a higher rate could be sustained because of urbanization. Summers does not rule out this outcome as he accepts a range of outcomes, with the most likely outcome being a reversion to the mean. The factors often cited for slowing growth are lower of productivity of capital as corruption and close connections determine where capital is allocated, misallocation of capital, large increases in credit in the economy since 2009 leading to bad debt in the financial system, aging society and demographics with increasing numbers of older people. Other reasons are the choices being made by Chinese leaders for slowing down to address the problems of air pollution and contamination of water supplies, inflation in housing prices, overdependence on exports, need to shift to increasing domestic consumer spending but unable to do this with the lack of spending power of large parts of the population because wealth is excessively concentrated in the upper ranks of society. The need to manage these forces ensuring some measure of stability depends on finding ways to reduce the growing concentration of wealth and power, in itself a challenge for the Communist Party elite. A combination of different factors with some still unknown factors are likely to play a part in this reversion to the mean for China, a situation encountered by every country so far in North America, Europe and Japan. This makes it even more important that each developing society structure its development around the most optimal goals with the least costs attached to the development....

Taiwanese contract manufacturer Hon Hai is moving quickly to address higher costs for workers at its manufacturing sites in coastal regions of China. After extensive media coverage of conditions at Foxconn factories, a number of suicides, and Chinese government policy that encouraged higher wages for workers in foriegn owned plants, Foxconn has moved to sharply increase wages at its plants. By the end of 2011 production in cities in the interior of China- Chengdu, Chongqing, and Wuhan, where costs are one third less- will be 25% of production, up from 10% in 2010. By 2012, this will be up to 50% of Foxconn's production, according to Yuanta Securities of Taipei. Hon Hai is lowering dividends to finance the shift. Fourth quarter 2010 earnings of Hon Hai were $742 million, down 26% over the prior year, even though revenues went up by 56% to $33.1 billon- reflecting the higher costs. Hon Hai's stock is down 20% in the past year on the Taipei stock exchange. Other locations being considered by Hon Hai are Brazil, Turkey and Slovakia. Brazil's President Dilma Roussef, said that Foxconn is considering a $12 billion plan for Brazil. Hon Hai is the only manufacturer of Apple iPads and one of two manufacturers of the iPhone....

Strikers at a Honda transmission factory in Hoshan, 100 miles northwest of Hong Kong are asking for raises of $117 or 800 renminbi in cash above the $132 a month or 900 renminbi that they are now paid. About 950 of 1900 workers at the plant are trainees, young people from vocational schools or high schools earn $132 a month. Older employees earn upto 1500 renminbi or $220 a month. The significance of this strike is that the Chinese government is tacitly encouraging the strike as it begins making moves to increase domestic consumption and make the economy less dependent on exports. This requires consumer's having larger purchasing power and higher wages. It also means that China will not remain the low cost manufacturer for manufacture goods makers around the world for very long. Consider the size of the increase and the policy change of the government and this implies a significant shift by China.

Research from Australian National University shows steadily improving conditions for migrant workers in China. Migrant workers were able to spend more time in cities- an average of 8.9 years. The hukou sysem ensures migrants return to rural areas when they have to raise a family. About 252 million migrant workers work in factories and construction jobs in urban areas. Migrants with children leave them with grandparents back home. Improving the conditions of these workers is important to reduce the wage and income disparities in China and to reduce inequality. About a fifth of the migrant population now has pension and health benefits. Creating a balanced economy with domestic consumer spending making a larger share of GDP also requires improving wages and benefits of migrant workers. Incoming prime minister Li Keqiang says in a statement on a government website: China "must take migrant rural workers and gradually change them into urban residents. This requires that we push forward household registration reform." If done seriously this will create a new kind of China as these migrant workers are integrated into urban society after years of being shunned and ignored by China's educated middle class. Professor Meng's research at Australian National University of migrant workers shows the proportion of migrant workers with unemployment insurance increased from 11% in 2008 to 21% in 2012. The research shows similiar figures for health and pensions. Improving their living standards also make it attractive for more young people from rural areas to migrate to cities increasing urbanization....
