The Permaculture Association have taken the lead on promoting research for permaculture and have a dedicated section on their website, their aim being to "build a strong evidence base for permaculture and improve permaculture practice". They have created a great booklet for anyone wishing to undertake their own research. Its very easy to read and purposefully designed to be accessible to everyone. Click here to view.

They have also launched the Permaculture Association's international soil tests a test that started in the UK last year and has now been extended to the international community. We are taking part in this.
