We are what we eat. It’s true for people — but also for cities and regions. The food we consume and the system that produces, distributes and disposes of it are as vital to San Francisco and the Bay Area as our systems for housing, energy, water and governance. That's why SPUR has launched a new Food Systems and Urban Agriculture policy program that will strengthen both the food system within the city and the region’s network of farms and distributors.

This year has been a wild one for redevelopment agencies in in California. First California voters passed Proposition 22, which prevented the state from raiding redevelopment agency funds. Then Governor Jerry Brown vowed to abolish redevelopment agencies and got fairly close to doing so. Now redevelopment agencies have once again headed to the chopping block, only this time it’s for real.

In the history of San Francisco city planning, 2011 may go down as the year of the parklet. The idea to make streets more livable by converting parking spaces into public places debuted in SF in 2010, thanks to the city’s Pavement to Parks project, but the concept really took off this year. SF has welcomed 10 new parklets in 2011, for a current total of 15, and will add as many as 12 more by the end of the year.

But a gaggle of planners and economic development experts are already working hard to transform this area into an arts district anchored by a redesigned Market Street.

In the 1970s, we crossed a global threshold when the rate of human demand for natural resources began to outpace the rate at which nature could provide them. How do we know this? By measuring our “ecological footprint” — natural resource consumption as a function of goods and services purchased. Recently SPUR and the Global Footprint Network released a study of San Francisco's ecological footprint.
