Human behavior and land use affect air quality, and those effects are very distinct at the local level. A new environmental game fusing public participation, air quality sensors and web technology shows how.
Cities are polluted places, and everyone knows it. Beijing is just coming out of a month-long media barrage on the city's poor air quality. Los Angeles, the original City of Smog, has been hearing it for decades. And though the existence of pollution is well known, it's not so well understood.
A look at the impact of recent court decisions on the Los Angeles River, and how it may affect development on the watersheds of rivers and waterways across the country.
For the federal government to protect waterways like rivers and streams, they have to ask one basic question: Is this water navigable? It seems simple enough, but hidden in this straightforward question is a jungle of nuance and intricacy. For waterways, how this question is answered can literally make or break them. But more likely, it will just make things kind of fuzzy, which is exactly what happened when the Army Corps of Engineers set out to determine how to regulate the Los Angeles River. ...
Adaptation is a way of life. But we humans have been building our habitats and cities in pursuit of permanence. This is an unreachable goal. Making our cities and communities and lifestyles adapt to outside influences is typically an afterthought. We do tend to react, and we often react very effectively. But solving problems before they happen has never been a strong suit when it comes to urban development. This is especially true with regard to our impacts on the environment. A recent and bizarre example illustrates this point.
The example revolves around water, and takes place in Los Angeles. The city is geographically a desert where water is naturally in low supply -- but because of the marvels of modern engineering and science it is now plentiful enough to meet the staggering demand of 4 million residents.
Americans are furious about paying $4 a gallon, but the pump price in Britain is more than twice that. In California, lawmakers are considering a bill where drivers in car-happy Los Angeles County pay higher fees to fund public transportation projects.
NATE BERG: At more than four dollars a gallon, gas prices are already too high for many Angelinos. But a new bill moving its way through the state legislature could push that price up another nine cents. All that loose change would add up to create a county public transportation fund worth more than 400 million dollars a year.
Mr. MIKE FEUER (Democrat, California State Assembly): The status quo is not acceptable.
BERG: That's Mike Feuer a Democrat in the California state Assembly. He represents Los Angeles and is the author of the bill.
On the bus this morning I was handed a survey asking me to detail my satisfaction with the Los Angeles County Metropolitan Transportation Authority's public transit system. As a daily bus commuter, I was more than happy to spend my two cents, but I'm a bit skeptical that those two cents will really do anything.
The survey included 29 questions, mostly of the "Yes or No" variety. They asked about things like the relative safety of the bus, its timeliness, its quality, the courtesy of the driver, and other general questions about my personal preferences for and opinions of the system and its service.
This message is brought to you by the frustrated residents of a city where strip malls prosper and the stock of affordable housing struggles to keep up with demand.
A new strip mall being constructed at the intersection of Venice Blvd. and Western Ave. in Los Angeles inspired this public display.
Strip malls are in no short supply in L.A., and this is just one example of yet another being built in the city. Unmixed-use retail developments like this are popping up all over the place. Much less new housing is being built. And a sharply lower amount of new affordable housing is being built...
Can cities get back in touch with nature? Planners, developers, architects, and policy makers convened in Los Angeles June 7 to face the challenge and develop a plan of action to help bring life onto the rooftops of L.A.'s downtown.
"Nature" is increasingly represented in the urban world as an incidental garnish -- a potted shrub at the door of a towering high-rise; a bush inside the loop of a freeway onramp.
These greening gestures calmly try to suggest a connection between the urban environment and the natural one. Yet other than providing window dressing, they contribute little to counter the harm that cities inflict on the natural ecology.
So what is a densely developed and thoroughly paved American downtown to do? ...
