Green Options

A new report ranks ten leading world cities on their greenhouse gas emissions. It also examines how and why the emissions differ.

As the report says, over 50% of the world’s population lives in urban areas. Leading cities of the world, global cities, are the places where greenhouse gas emissions really need to be cut. The greenest city from the study is Barcelona and the worst is Denver.

My happy transportation moment of the week came when I stumbled across this most excellent song on the Muni Diaries. The rap was created for the Transit Authority of River City in Louisville, Kentucky to explain how to use the bike racks on their buses. The infectious chorus has been stuck in my head all week: “Bring it down, pull the bar, put it on, put it on, take it off, put it

My long held fantasy of a car-free Market Street became just a little closer to reality today. A transit improvement report was just approved by the San Francisco County Transportation Authority that encourages travel by bus, foot and bicycle along this busy thoroughfare. District 6 Supervisor Chris Daly, who requested the report, expressed his support for the positive changes being implemented that will limit

As a pollutant polycyclic aromatic hydrocarbons (or PAH’s as we call them in the business), are of concern because they have been identified as carcinogenic, mutagenic, and teratogenic (not good things if you were wondering). PAHs are created as a byproduct of the burning of coal, oil, and fossil fuels. Often they are of concern in urban areas where there is a higher carbon footprint, and it forms that nice cloud of yellow smoke you see floating over some of your major cities.

Now, new research out of Columbia University is showing that exposure to PAHs, can reduce neonate’s intelligence. The study performed in New York city where PAHs are in no short demand, showed IQ scores that were 4.31 and 4.67 points lower, respectively than those of less exposed children.

That was one of the many probing questions that the visionary former mayor of Bogotá Colombia, Enrique Peñalosa, asked a packed auditorium in San Francisco last night. How do we define what makes a good city, what is our criteria? What makes an urban environment desirable and livable, and how do we judge the quality of life? What is socially and environmentally sustainable?

There’s been some interesting thoughts floating around the internet about rural, tacit and generational knowledge that we as a species are losing.

It seems strange to think that we could lose knowledge, especially in today’s world of information on demand, but if you think about it, certain skills and know how are hard to come by.

At the end of 2008, over one half of the world’s population lived in urban areas. Urban lifestyles come with their own characteristics and culture and so do rural lifestyles. Urban populations don’t have ready access to many of the experiences as rural populations do. General knowledge of where our food comes from for example, the simple act of gardening, knowing the planting seasons, identifying plants and knowing when to harvest; having the understanding of why bees are important, is not something that city dwellers grow up experiencing and knowing.

Based on this, I consider myself very luck to have grown up in a semi-rural area. I was close enough to a city but within easy distance to farms, lakes and rural towns. I learned many things because of this, both craft related and non-craft related and continue to acquire various tactile knowledge (err tacit, but I like tactile better) and I hope to never stop.

With two seats, two wheels, and a maximum range of 25-35 miles (at 25-35 mph), the P.U.M.A. (which stands for Personal Urban Mobility & Accessibility) won’t work for your next road trip. But this new concept vehicle, a joint project of GM and Segway, may be just the ticket for the driving most of us do on a daily basis.

The vehicle was introduced to the [...]

Tourism is the world’s largest and most promising industry. The concept of ‘eco-tourism’ is perhaps the most abused, little understood and least explored. Going to the mountains or a National Park and all other forms of natural tourism are often, though not always, marketed as ‘eco-tours’. While Ecotourism can be distinguished from nature tourism by its emphasis on conservation, education, traveler responsibility and active community participation, there is a severe paucity of efforts and attempts in the right direction for conducting such eco-tours.

Now, a youth led organization and an urban think tank in Delhi, India has taken to itself to research and explore ‘urban ecotourism’ as a means to connect the citizens back to their city, and raise awareness about the ‘nature in the city’. Underlying to this initiative is also the understanding that for the first time in human history, a majority of people live in cities or towns and that cities are the future of the world!

Everyone knows the very tastiest tomatoes are homegrown, lovingly staked and watered at regular intervals until they’re big and red and ripe. Until recently, such simple pleasures were reserved for rural dwellers but the growing movement for urban farming is starting to change all that. While container gardens and green rooftops have made urban agriculture more common, a new system called a Portable Farm may take it a step further.

48° Celsius is the highest temperature that the city of Delhi, India has witnessed in its recorded history. 48° Celsius is also a reference to the exigencies of global warming - which can be felt in Delhi’s continuously escalating summer temperatures each year. Delhi, by any score, qualifies as one amongst the world’s most dynamic and complex urban settings. Like most other urban centers of this country and of the south Asian region, the city of Delhi is characterized by multi-layered historicity and multiple urbanisms that get expressed in varying conditions within its cultural and physical fabric.

With this as the backdrop, and as a combined Goethe-Institut and GTZ initiative, the 48c Public.Art.Ecology Festival was recently celebrated in Delhi. A large empty bucket, a tree hanging from a crane, a hanging garden for want of space, a crash landing, cycle-rickshaws as local story-tellers, a bamboo art, a step-well with a large inverted mineral bottle on top…Delhi witnessed it all this December!

Last week I rode my bike to San Francisco’s City Hall to see Bill Basquin’s art show at Supervisor Ross Mirkarimi’s office; as I pedaled up through Civic Center Plaza my gut wrenched as I saw the large empty space where the beautiful City Hall Victory Garden used to be. All that is left where the native flowers, organic fruits and vegetables recently flourished is a lonely Christmas tree.
