i was watching Ted talks on netflix tonight and came across a guy named Miguel Medialdea in spain, he was being talked about in the viedo i'll link to in this thread but basically the story is thus:
miguel bought a farm that for years had been used for cattle farming, now this farm was placed right on some wetlands and thus the previous "farmers" had pumped all the water out via canals and channels, in the process the wiped out 90 some percent of local bird life and destroyed the once thriving ecosystem, as well as their attempt at running a business
when miguel purchased the land he simply flipped it around and allowed the water from the dirty river to flow back in, now miguel i guess is a bit of a bioligist and spent years in africa prior studying the stuff down there but has basically turned this once barren wasteland in to what i would describe as a near perfect (from the little ive learned about it thus far) permaculture fish farm, and i would say it beats the LIVING HELL out of aquaponics for commercial purposes
this dirty river water goes through his system and comes out pure as it pours into the atlantic
i THINK he may just be the farm's bioligist and not the owner? unfortunately im not pulling much up on this guy...
just watch this TED talk and see if youre as interested in this guy and his farm as i am:
