It's a mid-rise building that encompasses nearly an entire city block, usually developed over a surfacing parking lot or under-utilized former industrial site. There are countless more examples, even at the townhouse level (two examples from Minneapolis' downtown: here and here). Certainly, the loss of a parking lot is nothing to shed a tear over, but this building typology, which currently represents our American view of 'urban', presents itself as somewhat problematic.

The report "Innovation and the City" [PDF] is an important addition to our knowledge of urban policy innovation. It summarizes the results of a six-month research effort by policy researchers at New York University's Wagner School of Public Service and the New York-based Center for an Urban Future. The research team interviewed over 200 experts (including our own Emily Badger) and surveyed more than 120 policy innovations. (I should disclose here that I am Global Research Professor for the NYU School of Continuing and Professional Studies).

What makes some places succeed while others fail? In evaluating thousands of public spaces around the world, PPS has found that successful ones have four key qualities: they are accessible; people are engaged in activities there; the space is comfortable and has a good image; and finally, it is a sociable place: one where people meet each other and take people when they come to visit. PPS developed The Place Diagram as a tool to help people in judging any place, good or bad:

n 2011, the World Bank initiated the Partnership for Sustainable Cities, a group of leading urban actors with a mission to collaborate on city development around the world and foster city-led sustainable development. This synthesis paper, Building Sustainability in an Urbanizing World, is a product of the partnership's early discussions. In this paper, members of the partnership have collaborated to identify and analyze the issues that guide their work together. The report summarizes the sustainability issues faced by cities and points toward the road ahead. It reviews successes in policy as well as investment and discusses what is needed to reach out to the rapidly growing cities of the developing world and make them effective users of existing knowledge. Examples of programs established by the partners are described in both the text and the Annexes. This report aims to be useful to the partners who contributed with knowledge and experiences, to cities who may benefit from an honest discussion of what works and what needs improvement, and to businesses and development practitioners entering the wide world of sustainable cities.

As transport commissioner, Janette Sadik-Khan faced down critics to transform New York with 400 miles of cycling routes, a bike share scheme and the remodelling of Times Square. Any city can do it, she tells Peter Walker

In the old photograph, a lonely farmhouse sits on a rocky hill, shaded by tall trees. The scene looks like rural Maine.

Not so long ago, all things considered, the intersection of Broadway and 84th Street didn't exist; the area was farmland. "The Greatest Grid: The Master Plan of Manhattan, 1811-2011," now at the Museum of the City of New York, unearths that 1879 picture of the Brennan Farm among other historic gems. The show celebrates the anniversary of what remains not just a landmark in urban history but in many ways the defining feature of the city.

Getting the right city density - generally expressed in the US as people per square mile or homes per acre - to support sustainable and pleasant living is one of the trickiest problems we face as we address the future of our communities. The typically low densities of suburban sprawl built in the last half of the 20th century, despite their popularity at the time with a considerable share of the market, have been shown by a voluminous body of research to produce unsustainable rates of driving, carbon emissions, pollution. stormwater runoff, and adverse health impacts.
