12. Why Aquaponics ? Advantages Reduced labour Higher production rate Provides income from two separate products Aquacultural waste products are used A lot of current research and improvements going on

13. Why Aquaponics ? Advantages Less pests and diseases (if controlled) Reduced carbon footprint Reduced water loss Makes use of dead space  Rooftops  3-D vertical dimension Vertical Drip System Towers

14. Disadvantages High initial cost  To fill up water tanks  To build the system (Greenhouse, pumps etc.) Requires skill and know-how Constant monitoring of water parameters Pests and diseases can be devastating Limitations concerned with fish species reared Competitive market prices Why Aquaponics?

15. Organic Aquaponics Natural fertilizer Natural minerals (snail shells) Good marketing – labelling Other Possibilities Use of Technology Smart phone applications Pipe blockage warning System automation - Check out ‘urban aquaponics in Oakland’ on youtube or Kijani Grows on a search engine for more ideas -

16. Growing Indoors Can be used underground and indoors Artificial lighting May be a life-saviour in post-apocalyptic scenarios The Great Tennessee Pot Cave drug bust Other Possibilities

17. Growing Upwards Futuristic Concepts Growing locally Dedicated Skyscraper Farms Makes use of limited space availability Space missions Other Possibilities
