Water is finite on earth. There is a fixed amount of water which neither decreases or increases. Fresh water is a renewable resource because of the water cycle. From a human perspective the source of freshwater is rainfall. Most of this rainfall is used directly for vegetative growth, such as natural vegetation, pasture, rain-fed maize etc. This process, known as transpiration, is highly productive and produces in Southern Africa the bulk of food crops. | p cQc p Basics of Water Resources - Course Book WfiterNet CCR ISRI.
