Resource reliance- Food security
Present day scheme- Thanet Earth hydroponics
a method of growing plants without soil - grown in water instead, containing nutrients
units can be built in places where crops would normally never grow (e.g. old factories, warehouses, underground)
A hydroponic unit on a window sill can provide a continuous source of salad for a family
PRO: pests=controlled by natural predators not chemicals, less space as can be grown closely together, creates (up to 700) jobs
CON: expensive to set up and run, needs lots of energy
