In India, 2016 Recorded 30% More Forest Fires
Because of the dry conditions, the first four months of 2016 have already witnessed a far higher incidence of forest fire than in the past four years and a third more than last year. Chhattisgarh, followed by Odisha and Madhya Pradesh, has reported the most fires. However, forests have always been susceptible to blazes in the first half of the year prior to the monsoon rains and the winter season that follows. More @ Times of India

How NASA Is Using Space-Age Technology To Track Air Pollution
NASA is celebrated for space probes and Mars missions. But one of the agency’s next big projects could also make a major contribution to public health.
The U.S. space agency, along with agencies in Europe and South Korea, is making plans to launch a fleet of air pollution sensors into space. The sensors, which are being built by NASA, the European Space Agency and the South Korean government, are meant to monitor and track pollutants from orbit. Scientists hope NASA’s contribution to the project, called TEMPO, will provide a more accurate picture of how dangerous particles crisscross the Earth.
“Air pollution is really a global pollution,” Barry Lefer, a NASA scientist and project manager for TEMPO, told The Huffington Post. “Pollution from the U.S. travels to Europe, pollution from Asia travels to the U.S. And satellites are the best way to see the long-range transportation of pollution.”
The final product, which scientists say will be a “constellation” of pollution-tracking satellites, is still years away. But NASA plans to kick off the first phase of the project in May, when it will begin collecting air pollution data from the Korean peninsula in order to fine-tune its satellite-based pollution monitors.

Top 10 Best and Worst Tier II Cities in India, Based on Annual PM10 Pollution
Paris to Ban Cars for One Day a Month
Another four zones will also be pedestrian-only on Sundays, but just during summer months. The initiative, which will launch on 8 May - the second Sunday of the month due to a public holiday on 1 May – is part of a drive by Paris mayor Anne Hidalgo to reduce air pollution and smog in the city. The first Sunday of the month also happens to be the day when the city’s national museums have free entry.
He suggested London could learn a few lessons from the Paris example. “In London, which suffers some of the worst pollution in Europe, a traffic free day would be a welcome start," he said. “But we’re going to need much more than one day to prevent the thousands of early deaths each year caused by air pollution. London’s mayor has the powers to restrict diesel traffic on the worst pollution days. Boris Johnson’s successor must use them.
Real time air quality information from European Cities
The new measures in Paris are largely the result of a successful car-free Sunday in the city on 27 September last year. Between 9am and 4pm cars were banned in some key areas of the city, including the Champs-Elysees. According to air quality network Airpartif, which monitors pollution levels in Paris, there was a 40 per cent drop in harmful exhaust emissions in parts of the city.
In March last year the air pollution reached such high levels a one-day ban on all cars with odd-numbered registrations was announced, halving the amount of vehicles in the city from 5am and significantly reducing the harmful emissions. Mrs Hidalgo, who has prioritised combating pollution in the city, won a long running battle with the French government for the right to introduce similar emergency measures in the event of any future air pollution spikes.

Infographic - Emissions Analysis for Odd/Even Days in Delhi
Delhi announced to repeat the odd/even experiment from April 15th to 30th, 2016. Last time the experiment was conducted for two weeks between January 1st and 15th, 2016. The pilot was a social success, based on the reactions posted on the social media and printed in the other media. However, accordingly to CPCB, IITM, and TERI, the benefits of the program on the day time air quality was not immediately apparent in the ambient measurements, with likely large interference from meteorology. A difference in difference analysis comparing ambient PM2.5 data between Delhi stations and non-Delhi stations showed 10-13% drop in the day time concentrations.
In December, 2015, we released an infographic on possible benefits of restricting the on-road vehicles during the day time. Below is an emissions analysis comparing the emission rates from the passenger vehicles during a regular day and an odd/even day, based on what we understood has transpired during the two weeks of January, 2016.
Based on the monthly and seasonal air quality trends, April is one of the months with better air quality, compared to January. Question – do we need to repeat the experiment to know what is good for us, again? We will stick with our assessment on the need for an additional 15,000 buses in the city, to support a safe, comfortable, and reliable public transportation system, which will eliminate any need for such experiments.

Power Consumption Peaking in Delhi Due to Heat
The city is battling the scorching sun with residents staying indoors and switching on the air-conditioners. It is just mid-April, but power consumption in the Capital has already crossed the 4,300 MW mark.
List of Power Plants Supporting Delhi
Outages have already started in residential areas with many people saying they were not informed about the power cuts. If the heat and power demand keep surging at this rate, experts say that peak demand may cross 6,000 MW by June or July. The highest power demand Delhi has met was 5,925 MW on July 15, 2014.

With this, the Capital became one of the largest consumers of electricity, surpassing the demand of all North-East States put together, besides Mumbai, Kolkata, Bihar and Odisha.
“The highest power demand this season was 4,343 MW at 3:20 p.m. on Saturday, which at 42 degrees Celsius has been the hottest day of this year so far. On Sunday, the demand was 4,170 MW,” said a power official.
Some areas, in fact, saw power cuts that stretched for over four hours. “Last year, people were informed at least a day before a scheduled outage. We ourselves could track the same on websites of the State load despatch centre and discoms. But now, we can only see the outages that have already happened,” said Vivek Khanna, a resident of Mayapuri, which saw a power outage of two hours due to a “breakdown” in the area’s distribution network.
Areas that saw power cuts over the weekend include Shiv Vihar, Tagore Garden, Ambedkar Nagar, Janakpuri, Panchsheel Park and Madhu Vihar, among others. Shiv Vihar faced the longest power of four hours. While discoms maintained that there was no power cut due to shortage of electricity, they said that on many occasions outages occur due to repair work or breakdowns due to excessive load.
The city, meanwhile, is likely to get some respite with a dust storm and thunderstorm in the forecast for Monday - see the forecasts @ www.indiaairquality.info

Asia Won't Abandon Coal
Reports of coal’s death appear to have been greatly exaggerated, at least judging by major Asian importers’ continued commitment to the black gold. Despite reviving nuclear energy, Japan has given the green light to more coal-fired power plants, after importing a record amount of thermal coal in 2015. Meanwhile, coal demand is set to hit a new record high in neighbouring South Korea, while Taiwan’s new government could back increased coal imports to replace ageing nuclear reactors.
Added to the emerging demand from ASEAN and India, and suddenly coal bulls have reason for optimism after a year to forget for the global industry, including a drop in demand by China. China accounted for 50% of global coal consumption in 2014, but now plans to cut around 500 million t of production over the next 3 – 5 yr. This would be achieved by closing more than 5000 coal mines, retraining and relocating workers and not approving any new mines for the next three years.
IEA said it expected worldwide coal consumption to continue growing at a rate of 0.8% a year through to 2020, with the strongest growth seen in ASEAN (up 7.8% a year) and India (up 4.1% per annum). India is seen as replacing China as the world’s largest coal importer, with Australia deposing Indonesia as the largest exporter.
With key Asian economies turning to coal for affordable and abundant energy, some 400 GW of power generation capacity – roughly equal to the combined installed capacity of Japan and South Korea – is expected to be added across the region through to 2040, of which 40% will be coal-fired, the World Coal Association noted. Japan could build as many as 41 new coal-fired power plants over the next decade, with some 23 GW of new coal capacity under development as of 2015 compared to total capacity of 41 GW in 2014. According to the Korea Energy Economics Institute (KEEI), South Korean coal demand will increase by over 6% to more than 140 million t in 2016, following the startup of nine new plants with a combined capacity of 7.7 GW.

Delhi CM... Odd/Even Did Not Lower Pollution As Expected, However, It Reduced Traffic Congestion
@ Live Mint - Delhi chief minister Arvind Kejriwal on Wednesday said the implementation of the odd even scheme in January did not lower pollution “as much as expected” but it significantly helped reduce traffic congestion in the city.
“Odd even did lower pollution but not as much as expected, however, it significantly reduced traffic congestion, the roads were cleared and people liked it very much,” he said in reply to a question by a girl student at Sarvodaya Balika Vidyala in New Delhi.
Infographic - Emissions Analysis for the odd/even days
The odd even scheme was implemented on an experimental basis from 1 January to 15 January in view of high air pollution in the national capital. The second phase of the scheme will commence on 15 April.The government is taking other measures to check air pollution in the city including introduction of luxury buses with increased frequency to popularise public transport and vaccum cleaning of the roads, he said. “In the next 2-3 months, we will ensure vacuum cleaning of over 1000 kms of roads in the city,” he said.

China's Power Use Up 5.6% in March, 2016
@ China Daily - China's electricity consumption rose at a faster pace in March as economic activity and residential demand picked up. Power consumption rose 5.6 percent year on year last month, reaching 476.2 billion kilowatt hours (kWh), said Zhao Chenxin, spokesperson for the National Development and Reform Commission, at a press conference.
The growth accelerated by 1.6 percentage points from February and improved markedly from a 2.2-percent contraction in March last year. For the first quarter of 2016, power use increased 3.2 percent year on year to 1.35 trillion kWh, with the growth rate up 2.4 percentage points from the same period of last year, Zhao said. He attributed the recovery to stronger demand in the service sector and households, which contributed to an increase of 3 percentage points in the first-quarter growth.
Power use by the service sector jumped 10.9 percent year on year in the first three months, up 4 percentage points from a year earlier. That by Chinese households gained 10.8 percent, up 8.2 percentage points. The financial, real estate, catering and hotel industries all recorded faster increases in power consumption, according to Zhao. Electricity used by the industrial sector climbed 0.2 percent in the first quarter, exiting negative territory but still at a relatively low level of growth, the spokesperson said.

Oil consumption also pointed to a stabilizing economy, with March consumption of refined oil rising 7.2 percent year on year, improving from January and February. Diesel consumption, which reflects industrial and agricultural activity, went up 3 percent in March, compared with year-on-year drops in January and February, Zhao said. China's economy expanded by 6.9 percent, the slowest pace in 25 years, in 2015. First-quarter economic data will be released later this week.
Delhi's Car Limits Won't Clean Up City's Filthy Air
@ CNN - New Delhi is preparing to pull millions of cars off its streets for the second time this year as the local government searches for a way to improve air quality in the world's most polluted city.
The driving restrictions, dubbed "odd-even," will limit drivers to using their cars on alternate days for two weeks starting Friday. The idea is that fewer cars on the road will reduce vehicle emissions and improve air quality.
Just one problem: Experts say the program will likely have only negligible benefits, and is a far cry from the comprehensive approach needed to markedly improve air quality in the megacity of 20 million. "People are just rallying behind a feel-good policy," said Rahul Goel, an assistant professor at Shiv Nadar University, who studied traffic patterns during the initial phase of "odd-even" in January. Goel's team found that while car traffic eased during the experiment, potential emissions improvements were offset by an increase in the number of motorcycles and autorickshaws on the road. A second study, conducted by researchers from the University of Chicago, found there was a 10% decrease in air pollution levels during the program's initial phase.
"Did it work in January? With a bunch of caveats, yes," said Santosh Harish, assistant director of EPIC India, who noted that changes in weather and commercial traffic patterns can make it difficult to identify the source of air pollution improvements.

Converting to Hybrid Cars in Delhi (40% Reduction in Operating Costs)
@ Indian Express - Delhi will need radical measures to tackle its air pollution problem and the Delhi government’s odd-even initiative is a just one of the many things that can be done. IP university graduate Nikhil Khurana seems to think he has a better alternative — get more cars to go hybrid.
Hybrid cars run on more than one energy source, for instance petrol plus electricity, and also fall under the exempted categories in Delhi’s odd-even scheme. In India, the options available in the market under clean/alternative fuel category are rather few and some of these vehicles are priced beyond the reach of a regular customer. However, 23-year-old Khurana has developed a ‘Hybrid car conversion kit’ which can convert a normal car into a hybrid for around Rs 1 lakh. “This is our published patent technology and apart from providing a clean or alternative fuel technology, the hybrid kit also increases the mileage of a car by 40 per cent and reduces its running cost by 30 per cent,” says Khurana.
After the hybrid car conversion kit designed by Folks Motor — a company set-up by Khurana with his friends — is installed, the vehicle can be easily run on either fuel or power modes. “Currently we are offering fuel plus electric kits as the government regulation doesn’t allow us to use this technology with CNG,” he says. “Once the car is running, the batteries get charged automatically and can be used to drive the vehicle at a maximum speed of 60 km/hour.” So, if a car runs around 10 km on fuel then it can run for 4 km on the batteries improving the total mileage by 40 per cent,” he adds. The battery charges to its maximum limit if the car runs for 70-75 km and gives extra mileage of 30-35 km.

The Best and The Worst of the Pollution Masks
This is an article @ My Health Beijing
Which mask is the best against pollution? I can’t really answer that for everyone, as our faces have different sizes and shapes. I’ve recently shared results from three large tests, which unfortunately didn’t review many of the consumer masks I’ve used. But I can now tell you exactly which of those popular masks is perfect for me, and maybe we all can learn a bit from my adventure. Here’s my tale.
Selling masks in India is the new big business
In my seemingly never-ending quest for the best research on masks, I recently started to correspond with the research team at 3M, and during our conversations they very nicely offered to let me use their TSI Portacount Pro+ machine at their testing lab in Beijing (with no oversight of my results or article). This is the most widely used machine to officially test a mask’s effectiveness on a person’s face, and on a nicely smoggy day (another typically hazardous AQI over 150) I tested nine masks to find out which worked best for my face: three 3M models; Totobobo; Vogmask; Respro Techno; I Can Breathe Honeycomb; Lvdun 绿盾; and a surgical mask.

Delhi Government Initiatives.... Odd/Even Phase 2 Starts on April 15th, 2016
@ Economic Times - Delhi government today issued a notification on the fortnight long oddeven car rationing scheme that comes into force from April 15, but there is still no clarity as to how parents would pick up their children from schools during the implementation period. The Arvind Kejriwal government has decided to exempt women and cars carrying schoolchildren in uniform in the second round of the road rationing plan. Chief Minister Arvind Kejriwal on Saturday said that there are cases where a child may not be in the car on one side of the journey and it will cause a little trouble to parents. Kejriwal advised parents to explore the carpooling option or "adjust" their children with neighbours as there will be just nine working days during the scheme.

Indian Ports More Cargo Than 7 Seven Years Ago
@ ToI - India's 32 prominent ports handled 1,080 million tonnes of cargo in 2015-16, compared to 1,052 million tonnes in the previous year as exports fell through the year and import remained muted due to the economic slowdown and a fall in the value of key commodities, led by oil and metals.
Data, however, showed the 12 major ports witnessed a 4.3% rise in cargo traffic, estimated at 606 million tonnes. The private sector players, which have an over 40% share, saw an under 1% rise.Cargo handled by them increased from 471 million tonnes to about 475 million tonnes during 2015-16. Sources said one of the major reasons behind this is the decline in import of coal because of increased domestic production.
Industry insiders said several initiatives, including greater monitoring had improved the efficiency of major ports. The revival of port sector is also evident from the trend of a reduction in average turn around time from 2.55 days in 2012-13 to 2.03 in 2015-16. The average output of ship berth per day has also increased from 11,800 tonnes to 13,809 tonnes during this period.

Reduction in Smog Linked to Major Improvement in Children's Health
To assess respiratory symptoms, USC scientists studied children in eight California communities and defined bronchitic symptoms over the preceding year as a daily cough for at least three consecutive months, congestion or phlegm not related to a cold, or inflammation of the mucous membranes, according to Kiros Berhane, lead author and a professor of preventive medicine at the Keck School of Medicine of USC.
The study, published April 12 in the Journal of the American Medical Association, followed 4,602 children in three cohorts as they aged from 5 to 18. During 1993 to 2012, children and their parents from Long Beach, San Dimas, Upland, Riverside, Mira Loma, Lake Elsinore, Alpine and Santa Maria answered questionnaires about children's health. Air quality was continuously monitored in each community.
The study found that tiny particles called particulate matter 2.5 (PM 2.5) -- which can penetrate deep into lungs and cause serious health problems -- dropped by 47 percent from 1992 to 2011 in the study region. USC researchers were able to associate cleaner air with improved children's respiratory health. Kids with asthma were 32 percent less likely to suffer from bronchitic symptoms, and children without asthma experienced a 21 percent reduction in these respiratory problems.
Moreover, nitrogen dioxide, which can reduce resistance to respiratory infections, decreased by 49 percent in the same two decades. USC researchers linked the drop in nitrogen dioxide with a 21 percent decrease of bronchitic symptoms in children with asthma and a 16 percent decline of bronchitic symptoms in kids without asthma.

Even Low Levels of Air Pollution Appear to Affect a Child’s Lungs
In "Lifetime Exposure to Ambient Air Pollution and Lung Function in Children," researchers report that children exposed to higher levels of air pollution, including fine particulate matter (PM2.5) and soot (black carbon), had worse lung function than those living in less polluted areas. By age eight, the lung function of children living within 100 meters of a major roadway was on average 6 percent lower than that of children living 400 meters or more away.
Researchers found:

Researchers found:
- Children living the closest to major highways had the greatest reductions in their lung function.
- Recent air pollution exposures most negatively impacted lung function measures.
- Children who experienced greater improvements in air quality after the first year of life (either due to a move or changes in local pollution around the home) had better lung function compared to those whose air quality did not improve as much.

Myanmar Increasing the Coal Share
@ Climate Change News - Myanmar’s new government is set to mushroom coal’s share of its energy mix, despite manifesto pledges to boost clean energy and cut air pollution. The National League of Democracy (NLD) took power last Wednesday, formally ending nearly five decades of oppressive military junta.
Aung San Suu Kyi’s party will stick to existing targets to increase coal-fired power from 2% to 30% within 15 years, as it expands energy access in a country with one of the world’s lowest electrification rates. That urgency will take precedence “resulting in a few steps back on climate change,” said Miguel Chanco, regional expert at the Economist Intelligence Unit. “After all, approximately 70% of the population still does not have any such access to power,” he said in an e-mailed statement. “On that note, the temptation of cheap coal will be hard to ignore and I suspect that the new government, at least in the near term, will pursue the broad targets outlined in the Energy Master Plan.”
Indonesian and Thai coal firms are reportedly lining up to build power stations. The World Bank, however, has refused to finance projects as they contribute to climate change and air pollution. Myo Myint, an energy expert at the bank, said in comments reported in February by Thai media: “There is still potential for hydropower and gas reserves left untapped. We have yet to explore coal and those reserves found so far are poor in quality.” “To my knowledge, we will have to import coal if we set up coal-fired power plants. So I believe we should first try to run on resources at hand.”
In 2011, hydro provided 74% of electricity, gas 21% and coal 3%. By 2030, they want a third of electricity to be powered by coal, 38% from hydro and 20% from gas. They are also aiming for 7.2 million new grid connections. Suu Kyi, who is set to govern despite being constitutionally barred from the presidency, was initially appointed as energy minister among three other briefs. She will now remain foreign minister and minister in the president’s office, a statement said on Monday.
The NLD pledged to promote small-scale renewable energy for households and reduce industrial air pollution in its manifesto pledge, Chanco said. The state committed to increase forest cover to 30% of land area and generate 38% of its electricity from hydropower by 2030, in a submission to the Paris climate accord last year.

Golden Temple Turning Brown
To cut down on pollution, environmentalists and religious leaders have launched a campaign that includes persuading farmers to stop burning spent crops to clear their fields, removing industry from the area and cutting back on traffic. The famous community kitchen or “langar” that serves up to 100,000 people free meals every day at the temple is also switching from burning wood to cooking with gas.
But so far the campaign hasn’t had much impact, with change happening slowly and still no pollution monitoring equipment installed. “As far as pollution goes, we are paying attention,” said Jaswant Singh, environmental engineer at the State Pollution Control Board, a government regulatory authority. “We are in the process of procuring equipment so that we can check the pollution area, pollution from every source on a day-to-day basis.” Officials have also banned burning trash or cooking with certain fuels in restaurants and communities nearby, but enforcement so far remains weak.
Delhi Government Initiatives.... 1260 km in Delhi to be Dust Free - Vacuum Cleaning and Greening

New Tesla Model-3 Costs $35,000
These early buyers didn't know what the car would it look like -- a lot like a smaller Model S with an up-turned nose -- or that it would have a starting price of exactly $35,000. They also didn't know that it would go from zero to 60 in less than 6 seconds and have a range of at least 215 miles. "We don't make slow cars," CEO Elon Musk said at the car's unveiling, adding that these are minimum specs the company hopes to exceed. "You will not be able to buy a better car for $35,000, or even close, even if you get no options," he said later.
