THE URBAN DESIGN LAB
With the generous support of the Doris Duke Charitable Foundation, the Urban Design Lab at the Earth Institute, Columbia University has conducted this comprehensive assessment of the potential for urban agriculture in New York City (NYC). This project is the first large-scale analysis of its kind for NYC, and while it is not definitive, we hope that the information and research will provide a baseline for understanding the critical issues related to urban agriculture in our city.

LOS ANGELES COUNTY METROPOLITAN TRANSPORTATION AUTHORITY
The Los Angeles County Metropolitan Transportation Authority (Metro) recently began studying the ways in which bicycling, for transportation and in combination with transit, can reduce automobile use and lower greenhouse gas (GHG) emissions…The purpose of this study is to establish the benefits of providing an integrated transportation system where bicyclists are accommodated at train stations and on trains.

Pedestrian and bicycling infrastructure such as side-walks, bike lanes, and trails, can all be used for transportation, recreation, and fitness. These types of infrastructure have been shown to create many benefits for their users as well as the rest of the community. Some of these benefits are economic, such as increased revenues and jobs for local businesses, and some are non-economic benefits such as reduced congestion, better air quality, safer travel routes, and improved health outcomes.

HARVARD CENTER FOR RISK ANALYSIS
Traffic congestion is a significant issue in virtually every urban area in the United States and around the world. Anyone who spends any time commuting knows that the time and fuel wasted while sitting in traffic can not only be annoying, but can lead to real economic costs. An examination of the peer-reviewed literature shows that there are many previous analyses that estimate the economic costs of congestion based on fuel and time wasted, but that these studies don’t include the costs of the potential public health impacts. Sitting in traffic leads to higher tailpipe emissions which everyone is exposed to, and the economic costs of those exposures have not been explored.
To reach the ever growing demands for water in the Orange County Water District, Siemens was able to come up with a cost efficient and environmentally sound solution – Memcor®. This is a submerged membrane microfiltration system, supplying 87MGD (329 MLD) of water to a reverse osmosis unit, followed by advanced oxidation. It makes groundwater […]
