A raised bed 'Waterwise' cropping system
"Approximately 97% of the world's water is in the oceans, 2% is locked up in polar ice-caps, with the remaining 1% in the worlds, rivers, lakes, ground water and atmosphere - a ten days supply for the world's population, unless re-cycled. Gardeners are becoming more aware of the need to save water and garden accordingly. This lecture covers water conservation and how to make and maintain beautiful gardens using the minimum amount of water."
