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

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

Why Aquaponics? 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

Other Possibilities Organic Aquaponics • Natural fertilizer • Natural minerals (snail shells) • Good marketing – labelling 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 -

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

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

Other Possibilities Taken from the movie ‘Sunshine’
