Vertical Farm – Resourcing space

Posted in Models, RDAG by Devin Maeztri on April 20th, 2009

The Vertical Farm project was initiated by lecturer, Dickson Despommier, and his students at Columbia University in New York City.

The Vertical Farm is a concept of a thirty-story urban farm producing fruit, vegetables, and grains with a greenhouse on every floor. Citing factors such as the need for reforestation and the future growth of world’s population, Despommier believes that cities must learn to feed themselves. Depending on the crops being grown, a single vertical farm could allow thousands of farmland acres to be permanently reforested.

With about 160 of these buildings, you could feed all of New York.

The Vertical Farm would use hydroponic methods to feed 50,000 people. By growing crops in a controlled environment there would be minimum risk of disease, weather related disasters, less likelihood of genetically modified “rogue” strains infecting crops, and all food could be grown organically, without minimum waste.

Features of Despommier’s design include solar panels, a wind spire, glass panels, a central control room (allowing for yearround,24-hour crop cultivation), circular design, an evapotranspiration recovery system and pipes (to collect moisture which can then be bottled and sold), a blackwater treatment system, and a pellet power system (to turn nonedible plant matter into fuel).

However, as Despommier concedes, it would cost hundreds of millions to build a full-scale skyscraper farm due to construction and energy costs. For more information visit http://www.verticalfarm.com/index.html.

Toronto Food Policy Council- An Example for the World

Posted in Models, RDAG by Devin Maeztri on April 16th, 2009

The City of Toronto created the Toronto Food Policy Council (TFPC) in 1991 in the absence of federal and provincial leadership on food security.

TFPC partners with business and community groups (including City Councillors and volunteer representatives from consumer, business, farm, labour, multicultural, anti-hunger advocacy, faith, and community development groups) to develop policies and programs promoting food security – the TFPC has been instrumental in putting Food Security and Food Policy development squarely on the municipal agenda in Toronto

ULTra Personal Rapid Transit System

Posted in Models, RDAG by Kate Archdeacon on January 21st, 2009

ULTra (Urban Light Transport) is a model of PRT that has developed beyond the concept stage and is currently being tested at Heathrow Airport’s Terminal 5. Personal Rapid Transport has been advocated since the 1950s as offering “on-demand, non-stop transportation, using small, independent vehicles on a network of specially-built guideways”. [wikipedia]

Bicycle-Bus Transit Systems

Posted in Models, RDAG by Kate Archdeacon on December 9th, 2008

By installing bike racks on buses and integrating the two transport systems, the viability of both cycling and bus transit (both of which are lower emission than the car) is increased.

Predit: research, experimentation and innovation

Posted in Models, RDAG by Kate Archdeacon on December 9th, 2008

This information is part of research into case studies provided by Liz Boulton, Logistick, at the recent Sustainable Freight Seminar.

Predit is a French programme of research, experimentation and innovation in land transport, started by the ministries in charge of research, transport, environment and industry. It is not so much a case study as a methodology or a project management system.

Tripsense Pay-as-You-Drive car insurance

Posted in Models, RDAG by Kate Archdeacon on December 5th, 2008

With “Pay as You Go” ™ drivers can purchase cover as and when they need it – and then switch it off when it is not required. While the scheme doesn’t offer extra discounts for “greener” vehicles, it may help to reduce unnecessary car trips, and can play a role in an integrated transport strategy.
