Vines in the sky


A



The farms of the future may be built right in the centre of your city. Suburban


sprawl combined with the vast economies of scale in operation in agriculture, have


typically driven food production far from populated centres, with an increase in


the cost of transport and risk of spoilage en route. However, the days of market


gardens on the edges of urban areas supplying fresh food straight to your table


may soon be over mass city-centre farming may soon replace them. A visionary


microbiologist and environmental lecturer, Dickson Despommier from Columbia


University in New York sees our future cities populated by a new kind of market


garden. The creator of this radical ‘vertical farming' idea describes the evolution of


the concept from an older project involving rooftop gardening in Manhattan.


While that was interesting, it couldn't be sustained on a mass scale. But it planted


the seed of another idea Looking at greenhouse projects in New York. the resulting


concept was large-scale, indoor urban agriculture in skyscrapers.



B



Following this, Despommier set up Jaboratory projects aimed at different design


challenges and attracted a wide range of enthusiastic collaborators and contributors.


He believes this vertical farming method could be a solution to some of the world's


most pressing issues. The world population is expected to grow by three billion to


8.6 billion over the next half century. By then, some 80 per cent of the world's


population will live in cities, and they will need to eat. At the same time,


conventional farm and grazing land takes up an enormous amount of space, with


over one-third of the world's surface currently used for agriculture. Despommier


figures that in the next five decades an area of new arable land roughly the size of


Brazil will be required to feed the world's growing population - land that simply


doesn't exist.



C



Despommier's concept relies on using green methods of architecture and


materials to build skyscrapers that house grow and produce crops. New materials


and technologies such as cheaper reflectors, which reflect sunlight where it's


needed, more efficient solar panels for energy and system-wide recycling are


integral to the plan. One unusual feature is the use of a type of shellfish to filter


water. These can clean urban sewage to a state suitable for irrigation.



D



'Outside, one acre (0.4 of a hectare) of land means one crop a year,' says


Despommier. ‘Indoors, you can grow one crop every three months. You can get


four crops a year' He suggests that 150 such buildings could feed the entire city of


New York for a year. Indoor crops require less pesticide and are less subject to the


problems in nature, such as drought. Some academics say that a single skyscraper


farm covering 1.3 hectares could produce enough food to feed 35,000 people for a


year- the same as a 420-hectare farm Each floor of the design would be rigged up


with hydroponic watering systems and artificial lighting, and solar panels to


provide electricity. However, vertical farming is not without its challenges. One is


light - artificial lighting uses a great deal of electricity and generates considerable


heat. Another is cost, with some AS93 million per building for construction and


A$$5.5 million a year for operation.



E



Among experts, opinions vary on whether the project can succeed Creating


conditions suitable for growth is a serious challenge, and some think the crop yield


would be too low to make economic sense. 'My biggest reservation is that the


basic premise is flawed. We already know how to increase food production from


existing land resources, particularly in areas with surplus land such as sub-Saharan


Africa. It's just that we do it incredibly badly at the moment,' says Rob Brook, a


rural development researcher at the University of Wales in Bangor. 'This is a rich


person's pipe dream.



F



Yet there is strong support elsewhere. Luc Mougeout, an advocate of urban


agriculture at Canada's International Development Research Centre, says the


vertical farm is not only possible, but will happen within this generation. 'It would


collect at one site a diversity of elements already at work in some form or another


around the world,' he says. Despommier has the backing of his university as well


as venture capitalists from the Middle East, China and the Netherlands.


If the vertical farming vision becomes a reality, we could find ourselves once again


enjoying fresh fruit and vegetables sourced from just-around the corner, except


these might come from the 45th floor.

Movements of the planets


People have pondered the movements of stars and planets for as long as humans have


been on this Earth. Long ago it was noticed that some of the lights in the sky seemed


permanent in relation to each other and these were known as the 'fixed stars', whereas


other lights moved about much more freely and were called 'the wanderers'. We now


know the latter as the planets and we also know that the stars are by no means fixed


but move in predictable patterns. That both stars and planets circled the sky over 24


hours was thought to be because they revolved around the Earth.



One early theory described the 'music of the spheres'. It was believed that the stars


and planets were fixed on glass-like spheres that were centred on the Earth and


created heavenly music as they moved, this latter belief possibly originating from the


humming in the ears at high altitude. The Greek astronomer, mathematician and


geographer Ptolemy was one of the first to suggest a pattern to these movements and


in his Ptolemaic system the Sun, the Moon and the planets each had a sphere that


moved independently of the others, and the stars were all fixed on the outermost


sphere. This system was thus able to account for the differing movements then


observed.




By the 16th century, more accurate measuring instruments were available, and using


these, even before the telescope was developed, a Polish monk, Nicolaus Copernicus,


spent much of his life making far more exact observations of the heavens. He tried to


explain the mathematics behind the planets' movements but found that the circular


movement of a sphere could not explain why, for example, Mars apparently stopped


and went backwards for a short time. He discovered that the planets' movements


could be far more easily predicted if not the Earth but the Sun were placed in the


centre of the system, and the planets circled the Sun rather than the Earth. The


problem with this explanation was that many people believed that man was the centre


of the universe, and so not everyone accepted it. Copernicus avoided this difficulty by


suggesting the theory merely as a method of more accurately working out the dates of


important celebration days. The theory got strong support in the 17th century, when


the eminent Italian mathematician and astronomer Galileo Galilei taught the


Copernican system to his students.



The telescope was invented in the Netherlands in the early l7th century and this


allowed far more accurate measurements of planetary motion to be taken. The


German astronomer Johannes Kepler used it to discover that the Copernican


observations were not quite correct and so could not be used to predict the orbits of
