Raised Field Agriculture in the Lake Titicaca Basin

Raised Field Agriculture
While reading my new Permaculture Magazine I was struck by an article that spoke of an ancient Incan way of agriculture called Raised Field Agriculture. They would dig up canals near lakes and pile the soil on the sides to create raised beds. These canals help the plants by providing water most, if not all, of the year. This also creates a micro climate because of heat retention from the heat retention qualities of water in the waterways, thereby protecting the plants from frost. If that is not enough to get you thinking of renting some heavy machinery… it’s reported that fish could have been raised there, creating a kind of aquaculture that at the same time replenishes the soil with some needed Nitrogen. Did I forget to mention canoeing?
