Here's a new project to support local food growing - it lets us record our harvests and makes the results available as "open data". You can download the spreadsheet and see what people are harvesting, what yields the best growers are getting etc. As more features are added it should be possible to download just the data for your area (avoiding the need for spreadsheet fu). The project is by Permaculture Melbourne and Growstuff.org - and Growstuff is a social business with no ads and which doesn't sell your details to anyone, so they depend on people taking out the optional paid memberships (hint, hint... starting at $10 per year).
Please spread the word, sign up, add your harvests. Links to share:
