As the world's human population grows, we're reducing the amount of agricultural areas and forests. That's why some architects are working on concepts for sustainable skyscrapers and vertical agricultural buildings. Here are some of the most interesting plans for the merging of the city and the farm.

The Dragonfly for New York City (Vincent Callebaut, 2011)


The 600 m high vertical farm building was planned to New York City's Roosevelt Island. It could contain 28 different farms for vegetables, meat, fruit and others. The building would be self-sufficient because of the solar panels and wind power.

Oasis Tower for Dubai (Rahul Surin and Synthesis Design Studio, 2009)

It would be able to provide housing for some Dubai residents and has vertical farms, which would produce enough food to feed 40000 people in a year. The tower will be powered by renewable energy.

Pig City (MVRDV, 2001)


The Dutch MVRDV's design is all about huge skyscrapers with automated pig farms. There is probably a Thunderdome joke in here somewhere.

Boatanic, Amsterdam (Damian O'Sullivan and Boatanic, 2010)


The concept is very simple: the Dutch Boatanic team want to convert discarded tourist boats into floating greenhouses. These unused watercrafts are really ideal for this use because of the large glass windows. The only example which was built two years ago has solar panels, a small urban windmill and water filtration system to the automatic irrigation.

Urban Farming and Media Interactive Network or Urban F.@.m.i.n for Manchester, UK (Jack O'Reilly, 2010)


The part vertical farm, part TV station was a pod-like plan of an architecture student that would include vegetables and fruits. The water could come from a canal, and the energy from renewable sources like wind power.

Clepsydra Urban Farming (Bruno Viganó and Florencia Costa, 2011)


The Clepsydra can be placed on an average rooftop of an existing building. It's a 10 story tall structure from stainless steel and glass panels and can produce food that is equivalent to six acres of farmland.

London Farm Tower for London, UK (Brandon Martella, 2011)


The hydroponic floors can recycle the greenhouse air, so it can help to the city to breathe. It has an agricultural capacity of 1 million cubic feet, (28000 cubic meters) and it's enough to produce the 20 percent of London's total food demands. The London Farm Tower isn't just for agriculture, but for education, markets and labs with an extra 1 million sq feet of (100.000 sqm) usable area.

London Tower Farm for London, UK (Xome Arquitectos, 2011)


The beehive-structured tower has a vertical farm in the center of the tower, but there are some small residential areas, too, so the people can access the fresh vegetables and fruits instantly.

Vertical Life Tower for Barcelona, Spain (Jared Moore, 2011)


The living, green facade hides a huge amount of green areas, homes and a vertical farm on the top floors.

Toronto Sky Farm for Toronto, Canada (Gordon Griff, 2009)


It provides enough food for 35000 people per year from the 59 stories.
