I dont know if this is the place to post this but here it is. How I haven't stumbled upon this before now is a mystery to me. I've not yet had a good trawl through it myself, but thought I'd post the link anyway as it does seem relevant (appropriate ;-) . I've just cut and pasted part of Appropedia's own desciption of the site "Appropedia is the site for collaborative solutions in sustainability, poverty reduction and international development through the use of sound principles and appropriate technology and the sharing of wisdom and project information. It is a wiki, a type of website which allows anyone to add, remove, or edit content. Registration is encouraged but not required for contributors. Appropedia has been described as an "appropriate technology wiki," but it is much broader than that - it is a green wiki, and a wiki for all matters of international development and aid. But most importantly, Appropedia is an open site for stakeholders to come together to find, create and improve scalable and adaptable solutions." https://www.appropedia.org/Welcome_to_Appropedia Some of the folks here may already know of it , but for those who don't I hope it's of use.
