I landed in Delhi at the tail-end of an experiment to limit the number of vehicles on the road. Here’s a piece in Nature about how researchers leapt on the opportunity to study the effects. 

New Delhi may be the world’s most polluted city, but it’s making an effort to relinquish that title. With pollution from particulate matter at potentially lethal levels early last December, city officials took a drastic step: they announced that they would temporarily restrict the use of private vehicles by allowing owners to drive only on alternate days, based on the sequence of their number plates.

The initial results of that 15-day trial, which began on 1 January, are now in.

Amazing things happen… (in the most polluted city on earth)

In which I report for Vice magazine from New Delhi, which the WHO determined to be the most polluted big city on the planet. It sure feels like it. 

New Delhi is choking on its own air.

On January 1, India’s capital made an attempt to address its status as the world’s most polluted big city, according to the World Health Organization, by implementing a temporary “odd-even scheme” for automobile use. Private vehicles could only be driven on days that matched their plate number or risk a $30 fine. There were loads of exemptions, including the two-wheelers that dominate the roads, hybrids, and cars driven by VIPs or women (with no men in the vehicle). There were jokes about “men riding in the dickey” — the trunk — of cars and more serious conversations about immediately buying a second car to get around the restrictions. But after the 15-day plan came to end, overall sentiment was high as researchers rushed to declare it a success or failure.

About 35 years ago, when most ecologists were still musing about how we’d deal with the ice age that models then showed was on its way, young scientists Gus Shaver, Terry Chapin and John Hobbie set up camp on an old abandoned airstrip at Toolik Lake on the North Slope of Alaska. Scientists tinker and so when they gazed at this wild and beautiful yet nutrient-poor place, bereft of nitrogen and phosphorous found in the temperate regions of the globe, they wondered what might happen [Read more…]

must india ravage to rise?

My double book review was just published in Caravan magazine, looking at Churning the Earth: The Making of Global India, by Aseem Shrivastava and Ashish Kothari, and Making Peace with the Earth: Beyond Resource, Land and Food Wars, Vandana Shiva’s latest. It’s loaded with (unanswerable) questions.

Is there nothing between the sleepy socialism of India’s first decades that admittedly did little to raise the standard of living for most Indians and the sell-out spree of the recent past that has created a growing chasm between the haves and the have-nots? What happened in the half-century between political independence gained and economic independence relinquished?

california condor faces lead menace

By Leave a Comment

After more than three decades on the brink of extinction, the California condor (Gymnogyps californianus) — the largest and most threatened wild bird species in the United States — is making a modest recovery, thanks to intensive captive breeding and medical intervention. But troubling data reported this week suggest that unless hunters change their practices, the condor will require extensive support in perpetuity if it is to survive in the wild. [Read more…]

an ill wind: the trouble with turbines

By Leave a Comment

I’ve been following with interest the rapid expansion of wind energy and its impact on wildlife. Excited that I had a chance to delve into the issue for Nature magazine. Here’s how it starts:

Marc Bechard turned a worried eye skywards as he walked among the limestone hills at the southern tip of Spain. It was October 2008, and thousands of griffon vultures — along with other vulnerable raptors — were winging towards the Strait of Gibraltar and beyond to Africa. But first they had to navigate some treacherous airspace. The landscape on either side of the strait bristles with wind turbines up to 170 metres high, armed with blades that slice the air at 270 kilometres per hour. [Read more…]
