Terra Preta Sanitation...
-------------------------------
is a systemic approach to link sanitation and agriculture to protect soil fertility and water ressources. Instead of polluting fresh water with human excreta and urine they are used to create Terra Preta soil. Terra Preta is a highly fertile black soil made by composting biowastes in addition of charcoal and faeces which are pre-treated by lactic acid fermentation. It was invented by an ancient Indio civilisation in the Amazon forest and is still fertile after hundreds of years when it was discovered about 30 years ago.
