Air Pollution in Urumqi, China


Urumqi, one of China's most polluted cities, plans to move dozens of factories from urban areas and tear down thousands of coal-burning boilers this year to clean its skies of their habitual winter smoke.

Link to the article..
The government of the Northwest China city, capital of Xinjiang Uygur autonomous region, aims to cut 5,000 tons of sulfur dioxide emissions this year, more than double the estimated 2,000 tons of emissions cut in 2010, said a spokesman for the municipal environment department Monday. Urumqi's severe air pollution is mainly caused by industrial activities and winter heating supply. The city emitted 128,000 tons of sulfur dioxide and 61,000 tons of soot in 2009. Residents complain that air pollution in Urumqi has grown so serious that the city seems to be constantly shrouded in thick black smoke during the winter.

Urumqi Mayor Jerla Isamudinhe said at the annual meeting of the city's legislature, which ended over the weekend, that the government would push to change the city's winter heating sources. About 5,000 coal-burning small boilers used for winter heating will be dismantled in favor of collective combined power and heat generation facilities, and the use of natural gas, the spokesman said. The cost of building the combined power and heat generation plants was estimated at 4 billion yuan, said the spokesman. In addition, 47 polluting factories would be moved from urban areas while 20 would be upgraded to reduce sulfur dioxide emissions, he said.

Sustainable Transport Award to Guangzhou, China

The award-winning transport system in Guangzhou, in south China's Guangdong province, includes not only Bus Rapid Transit but wide, tree-lined bicycle lanes and a tie-in to the large city's rail network.

This story is part of a special series that explores energy issues. For more, visit The Great Energy Challenge.

A bike-sharing program, wide bicycle lanes lined with trees, and a huge bus system that ties in with the city rail network are all part of the recipe for a winning transportation system in Guangzhou, China, according to the Institute for Transportation and Development Policy (ITDP).

ITDP, an international nonprofit that works with cities on projects to reduce greenhouse gases and improve the quality of urban life, named Guangzhou the winner of its 2011 Sustainable Transport Award at a ceremony Monday night in Washington, D.C.

Guangzhou clinched the prize, said Jessica Morris, senior program director for ITDP, largely because it surpassed expectations. The bus rapid transit system, which opened in February 2010, "carries an awful lot of people," as many as 800,000 a day, she said, making it one of the world's largest. Perhaps more importantly, the new bus system "hooks up seamlessly" with rail as well as "idyllic" bicycle paths and bike-sharing stations, and helps to make the city "more livable."

Serving More Than The Economy

ITDP has been working closely with Guangzhou to build out the bus and bike infrastructure, she said, and the city's recent transportation efforts make it a place that "goes against the idea of a burgeoning Chinese metropolis that's only serving the economy." Experts say that easing congestion and reducing pollution from the transportation sector in China—with its increasingly urban and car-buying population—will require coordination of land-use planning, information technology, and mass-transit development, as well as cleaner vehicles.

(Read more on China’s efforts here: "On China’s Roads and Rails, a Move To Greener Transit.")

Zhong-Ren Peng, who chairs the University of Florida's Department of Urban and Regional Planning and is an expert in transportation planning in China, noted in an email that Guangzhou did much work in transportation and planning in preparation for serving as host to the 16th annual Asian Games in November, just as Shanghai did in preparation for last year's World Expo.

The projects and progress that ITDP seeks to reward are about more than going green. According to Morris, the committee of organizations assembled to nominate and select cities for the prize look for three factors in a "sustainable" transportation system: The system should benefit both the city’s environment and its economy, and it should be equitable, meaning "you should be able to move about your city regardless of income level," she explained.

In recent years, the Sustainable Transport Award has gone to New York in the United States; Paris, France; Guayaquil, Ecuador; Seoul, South Korea; and Bogotá, Colombia. Ahmadabad, India, snagged the award last year for opening what the ITDP described as the country's first full bus rapid transit system.

This year, Guangzhou beat out nominees León, Guanajuato, Mexico; Lima, Peru; Nantes, France; and Tehran, Iran, where the "local climate, topography, and sharp growth in private cars have all conspired to create a lingering air-quality emergency over the city," said Lloyd Wright, Executive Director of Viva Cities, in a news release about the nominations.

Tehran's Effort Amid Controversy

Each of the nominated cities took steps in 2010 to shake up its transportation system, according to ITDP. Tehran's journey has been particularly fraught with controversy, as President Mahmoud Ahmadinejad and Tehran Mayor Mohammed Baqer Qalibaf have clashed over funding for an expanded underground rail system. One of the world's most densely populated metropolitan areas, Tehran also introduced congestion charging and expanded its bus rapid transit. "Even more boldly," according to the ITDP, Tehran's government has "begun the process of reducing fuel subsidies."

Over the weekend, however, the Tehran-e Emrouz newspaper reported that the Iran Foreign Ministry had denied Qalibaf permission to travel to the United States for Monday's conference.

Nantes made it into the ITDP's top five for its efforts to integrate bus and tramway systems, while also promoting bicycling. In Lima, a "long-awaited" first step toward "creating an integrated citywide sustainable transport system," came in the form of a new bus rapid transit system. And León has boosted rail and bus ridership while keeping the portion of trips taken by bicycle or on foot among the largest of any Latin American city at more than 39 percent, according to the ITDP.

Jiangping Zhou, ITDP's Policy Director in Beijing, believes Guangzhou’s efforts could be replicated in other Chinese cities. "If something can happen there," he said, "it can happen in Shanghai and Beijing."

Air Quality Today in Cities Across the World


Air pollution is a growing problem for not only the megacities, but also for 300+ secondary cities, which are following in the footsteps of the megacities (with population more than 10 million) and in line to face similar set of environmental consequences (air and water pollution) of motorization and industrialization, if the necessary policy and technical interventions are not put in place immediately.

Top 100 cities with the worst air quality in the World

Most often, the regulatory bodies have the responsibility of making these necessary and adequate decisions and are always in need for better data. Data not only to base the decisions on, but also to inform the public and media of the current situation and progress in the future. See a previous post on links to air quality monitoring is Asian Megacities.

For air pollution, the air quality index (AQI) is such an indicator.


The AQI is an "index" determined by calculating the degree of pollution in the city or at the monitoring point and includes five main pollutants - particulate matter (see SIM-10-2008), ground-level ozone, sulfur dioxide, carbon monoxide and nitrogen dioxide. Each of these pollutants have an air quality standard which is used to calculate the overall AQI for the city. Simultaneously, one can also establish the limiting pollutant(s), resulting in the estimating AQI.

Pollution in Beijing Today is Like London of 1950's (IHT)


Establishing this number in a forecast mode is not an easy exercise, as it involves modeling of emissions, dispersion of the pollutants depending on local meteorology and terrain, and presentation. However, a number of platforms (and groups) are established and in use, for the readers to choose and learn (and apply). We conducted a workshop on this topic in collaboration with WMO and IITM, in India and hope you will benefit from the material.
The city of Delhi is now the first city to have the air quality forecasting system and a methodology to calculate AQI in India.

Real Time Air Quality and Air Quality Index for Delhi, India


For dissemination, options are limitless and there are innovative ways to present the information to public and media - via balloons (in Paris), via websites (links below), via photo journals (in Beijing), via digital exhibition (in Madrid) and lasers (in Helsinki).

Subsidizing Diesel is Causing is Causing More Health Problems !!

Let me explain. We know global oil prices are going through the roof. Indian oil companies, dependent as they are on importing some 80% of their crude are bleeding. The price of petrol has been raised, as the joke goes, to make it more expensive than beer.

This also means that the differential between petrol and diesel price has grown. It makes even more sense for the next car buyer to buy an expensive personal car – perhaps even a Mercedes Benz – but run it on diesel. It even makes more sense to buy a fuel guzzling SUV and run it on subsidized diesel.

Soot Strategies in China !!

Global efforts to mitigate climate change are beginning to take aim at a once-obscure pollutant called “black carbon” in a shift that may bring policies to cool the planet to families preparing meals at home and farmers readying plots of land for planting.

Research shows that black carbon is also heavily impacting the glaciers of the Himalayas, another region of global significance. The “third pole” or “Asian water tower” feeds some of the world’s biggest rivers, including the Ganges, Yangtze and Yellow River, which together supply drinking water and crop-irrigation for some 1.5 billion people across 10 countries. According to estimates published last year in the journal Atmospheric Chemistry and Physics, black-carbon emissions have caused nearly 10% of the ice-cover loss in the Himalayas from 1990 to 2000, of which about 36% is attributed to Indian coal and biofuel burning.

Transport Policy in India

Article published in the Hindu, "fixing India's transport troubles", following the announcement of a new transport committee under the National Transport Development Policy Committee (NTDPC)

India that aspires to be an economic superpower is visibly in need of a transport policy that is in tune with the times. The constitution of a high level Transport Policy Development Committee, headed by the former deputy governor of the Reserve Bank of India, Rakesh Mohan, reflects this. The last time a comprehensive view of transport was taken at the national level was in 1980 when the B.D. Pande committee submitted its report. Much has happened since then. India's economic transformation from a near-closed economy to a fast liberaliser led to a significant stepping up of economic activity, particularly by the private sector, and resulted in higher individual spending capacity. While the former meant increased flow of goods and services, calling for better freight facilities, the latter translated into both higher purchasing power for personal transportation modes and higher effective demand for better public transport. Liberalisation has also spawned its own huge inequities. A fresh policy has to factor in the harsh reality that the overwhelming majority, in the region of 800 million Indians, live in poverty. This calls for a more active state role as a provider of subsidised transport and as an effective regulator, particularly since the trend is to move towards a system that facilitates private players.

The terms of reference of the Rakesh Mohan committee are wide: they range from “assessing the transport requirements for the next two decades” to “assessing the investment requirements” of the sector. Although there are several issues that jostle for attention, there is an urgent need to develop a comprehensive policy for road transport as this mode carries 87 per cent of India's passengers, moves 60 per cent of its freight, and is in serious disarray. Efficient inter-State, intra-city, and rural transport systems will reduce losses, improve connectivity, and open up more economic opportunities. The most shocking lapse of state policy is the decline of public transport. As a Parliamentary Standing Committee rightly pointed out, the decline of buses in the total fleet of vehicles from 11 per cent in 1951 to a paltry 1.1 per cent in 2004 has meant an increase in personalised transport. This leads to avoidable economic losses due to higher fuel expenditure, apart from widening inequalities. The retrogressive trend needs urgent reversal. A policy that accords primacy of space to an affordable, efficient, and integrated public transport system will be key to fixing India's transport troubles.

Earth Is Twice as Dusty as in 19th Century (Science Daily)

Link to the article

ScienceDaily (Jan. 12, 2011) — If the house seems dustier than it used to be, it may not be a reflection on your housekeeping skills. The amount of dust in the Earth's atmosphere has doubled over the last century, according to a new study; and the dramatic increase is influencing climate and ecology around the world.

The study, led by Natalie Mahowald, associate professor of earth and atmospheric sciences, used available data and computer modeling to estimate the amount of desert dust, or soil particles in the atmosphere, throughout the 20th century. It's the first study to trace the fluctuation of a natural (not human-caused) aerosol around the globe over the course of a century.

Mahowald presented the research at the fall meeting of the American Geophysical Union in San Francisco Dec. 13.

Desert dust and climate influence each other directly and indirectly through a host of intertwined systems. Dust limits the amount of solar radiation that reaches the Earth, for example, a factor that could mask the warming effects of increasing atmospheric carbon dioxide. It also can influence clouds and precipitation, leading to droughts; which, in turn, leads to desertification and more dust.

Ocean chemistry is also intricately involved. Dust is a major source of iron, which is vital for plankton and other organisms that draw carbon out of the atmosphere.

To measure fluctuations in desert dust over the century, the researchers gathered existing data from ice cores, lake sediment and coral, each of which contain information about past concentrations of desert dust in the region. They then linked each sample with its likely source region and calculated the rate of dust deposition over time. Applying components of a computer modeling system known as the Community Climate System Model, the researchers reconstructed the influence of desert dust on temperature, precipitation, ocean iron deposition and terrestrial carbon uptake over time.

Among their results, the researchers found that regional changes in temperature and precipitation caused a global reduction in terrestrial carbon uptake of 6 parts per million (ppm) over the 20th century. The model also showed that dust deposited in oceans increased carbon uptake from the atmosphere by 6 percent, or 4 ppm, over the same time period.

While the majority of research related to aerosol impacts on climate is focused on anthropogenic aerosols (those directly emitted by humans through combustion), Mahowald said, the study highlights the important role of natural aerosols as well.

"Now we finally have some information on how the desert dust is fluctuating. This has a really big impact for the understanding of climate sensitivity," she said.

It also underscores the importance of gathering more data and refining the estimates. "Some of what we're doing with this study is highlighting the best available data. We really need to look at this more carefully. And we really need more paleodata records," she said.

Meanwhile, the study is also notable for the variety of fields represented by its contributors, she said, which ranged from marine geochemistry to computational modeling. "It was a fun study to do because it was so interdisciplinary. We're pushing people to look at climate impacts in a more integrative fashion."

Vulnerability of Asian Cities to Climate Change

Access the full report on InfoChangeIndia

The report lists Dhaka in Bangladesh as the most vulnerable to climate change impacts. It is a large but relatively poor city and is located just metres above current sea levels. It is regularly impacted by tropical cyclones and flooding and has very limited adaptive capacity.

Jakarta and Manila are also extremely vulnerable cities and tie for second rank, largely because of their size, degree of exposure (both experience frequent flooding), and relatively low adaptive capacity. Kolkata and Phnom Penh tie for third most vulnerable city, largely because Kolkata is prone to saltwater intrusion and the effects of sea level rise, while Phnom Penh has very low adaptive capacity.

Each city is given a score card that lists particular vulnerabilities: to environmental exposure (storm threat, sea level rise, flooding/drought), socio-economic sensitivity (population, assets threatened) and inverse adaptive capacity, that is, its inability to adapt.

Finding Delhi, Loss and Renewal in the Megacity (Info Change, India)

Finding Delhi, Loss and Renewal in the Megacity (Viking Penguin 2010), an edited volume by Bharati Chaturvedi, attempts to address the changes in the national capital from the perspective of those who are a low priority for the planners. Perhaps more than any other city in India, Delhi exemplifies the pitfalls of huge investments that produce a city that fails to satisfy the basic needs of the majority of its residents. Of course things could change and the city could yet become a more democratic and less segregated space. But from the lived experience of millions of Delhi’s residents, especially those who have been rendered virtually invisible by the visioning exercises of a ‘global city’, ‘new’ Delhi seems less democratic, more fissured, than the old and historic Delhi.

Air Pollution in Kabul

Link to the article and pictures from Demotix.

KABUL, 6 January 2011 (IRIN) - KABUL, 6 January 2010 (IRIN) - Worsening air pollution in Kabul has forced the Afghanistan National Environmental Protection Agency (NEPA) to advise people to use masks or other protective devices during the morning and evening rush hours.



NEPA and the Health Ministry say air pollution causes up to 3,000 deaths a year and spreads skin, respiratory and eye diseases, and even cancer. The UN World Health Organization (WHO) says air pollution causes about two million premature deaths worldwide every year.

“Anyone can observe that the air in Kabul is highly polluted,” said Chiranjibi Gautam, an expert with the UN Environment Programme (UNEP).

“Up to 75 percent of the air pollution is from transport,” Najibullah Yamin, NEPA’s deputy director, told IRIN.



The country imports tens of thousands of second-hand cars every year. They predominantly use low-grade fuel which pollutes the air, NEPA said.



To discourage the use of state-owned vehicles and reduce pollution, the government announced that Thursdays are to be public holidays until March 2011. Afghanistan normally only observes Friday as a day of rest.

Critics, however, say the extra holiday is benefiting no one, as officials tend to use government vehicles for private purposes on days off. “It’s a joke which in fact is damaging the economy more than helping to reduce air pollution because congestion on Thursdays is no better than on other days,” said Kabul resident Ahmad Temor.

The government has not banned the use of government or private vehicles on Thursdays and Fridays, but merely “requested” that people refrain from using their cars “unnecessarily”.



Kabul’s inadequate public transport system does not meet the needs of its estimated 4.5 million inhabitants, pushing more and more people to buy cars.

Valley aggravates smog

“Kabul is a valley where in winter there is thermal inversion and because of it very low dispersion of pollutants takes place, thus increasing pollution levels,” said UNEP’s Chiranjibi Gautam.

Other main causes of air pollution and environmental degradation are rapid population growth and a largely unregulated urbanization.

The lack of trees, parks and other green areas exacerbate the city’s air quality, experts say. In cold winter months air pollution increases due to the burning of fuel and firewood for heating, they add, though the use of generators has decreased over the past two years due to US-funded electricity imports from neighbouring Tajikistan.

Meanwhile, officials accuse what they call a “land mafia” of plundering public land and illegally building houses, with little or no heed to the environment.

“The land mafia has seized green areas and builds houses and commercial buildings in areas which are crucial for environmental protection purposes,” said NEPA’s Yamin.

A lack of public awareness on environmental issues is part of the problem, he adds. “The last thing on people’s minds here is the air quality and the environment.”

Another Year... New Hopes and Wishes !!

a passage from NY Times

The coming of the new year reminds us, again, that we live, as we always have, somewhere on a sliding scale between utopia and dystopia and that we continuously carry our burdens and opportunities with us. 2011 is merely a new entry in our ancient custom of chronological bookkeeping, an arbitrary starting point for our annual trip around the sun.

But it is also so much more. Who can live without fresh intentions, new purposes? Who does not welcome a chance to start over, if only on a new page of the calendar? Life goes on, but it goes on so much better with hope and renewal and recommitment.

Last night was a night for banishing regrets. Today is for wondering how to live without new ones, how to do right by ourselves and one another.
