Farming on your roof?

  • Designers of a self-contained rooftop aquaponics dome known as the Globe (hedron) are hoping that their concept may help to address food security and are seeking funding to develop a prototype.
  • Aquaponics is a combination of aquaculture and hydroponics. If effluents from fish and their food that accumulate in water are channelled to plants, they can be consumed as nutrients, purifying the water for the fish in the process.
  • Designers suggest that a rooftop dome could feed a family of four year-round, providing it with sufficient fish, vegetables and herbs.
  • Other rooftop agriculture solutions are taking off across the US and elsewhere, utilising otherwise useless land areas and heat that would otherwise be absorbed by dark rooftops and radiated back into the environment, increasing urban temperatures.

Government should be aware of the development of the techniques and their potential to contribute to food security, however adoption of individual systems across households would bring implications such as the need for regulation to ensure food safety control of diseases etc.
