An aeroponics garden where roots are dangling in a mist of nutrient water and oxygen could be ideal for famine stricken countries. The fact that this kind of plant growing uses up to 95% less water than traditional farming and gardening. This will mean that it does not need to fight with other users of this precious liquid. Because there is no soil involved the farmer or the gardener does not need pesticides and that saves costs, because people in famous stricken countries simply do not have the money for expensive investments. As humanitarian aid the Western World should send specialised water pumps, solar panels, small computers and big trays instead of the tons of food that goes to this countries and that unfortunately hardly ever reaches the real hungry.
The fact that the roots and the plants just live on water and air, means that they grow faster and bigger. For a farmer in a famine stricken country this means that he can feed his people more and more often.
