Scientific applications and studies of Permaculture techniques.
This community invites members to document experiences and show tested and / or peer reviewed studies to gauge the effectiveness of applying Permaculture methods.
Permaculture appeals to many people because it appeals to common sense, but practitioners often depend on anecdotes for validation. Permaculture at it's core welcomes scientific methodology through it's emphasis on observation, interaction and incremental change.
Doing science doesn't mean being a lab drone, and you don't have to wear a white coat!
We'd like to see research on:
- No-till agriculture techniques
- Effects and instances of biodiversity
- Efficiencies of function stacks

It has been my experience that permaculture instructors can give interesting facts without sources.
I just found one source for a fact given in a workshop by Graham Calder three years ago. "Outside of 400 miles from the coast, rainfall to the interior of continents is entirely caused by the transpiration of forests". This turned out to be from The Hidden Life of Trees by Peter Wohlleben, and comes from the following study: Anastasia M. Makarieva and V.G. Gorshkov, "Biotic Pump of Atmospheric Moisture as Driver of the Hydrological Cycle on land," Hydrology and Earth Systems Sciences, 11(2) (2007): 1013-33, www.bioticregulation.ru/common/pdf/07e01s-hess_mg_.pdf

Fiat, and thinking errors among new graduates according to one farmer. A good summary of permaculture teaching benefits, drawbacks and areas where improvements are being made.

Literature review on composting cat feces. Looks pretty comprehensive
Cat litter composes around 80% of my home waste (the rest seem to be plastic food wrappers). This review contains info on T. gondii, Fecal coliform, Salmonella sp., Enteric virus, and Helminth ova, but not a complete review of what might be present in the poo. T. gondii from cats are responsible for 17% of all Pacific sea otter deaths (!) pittsburghpermaculture.org/wp-content/uploads/2010/02/cat-litter-composting.pdf
