Appropedia is a living library wiki, focused on success in two global initiatives:

  • Reduce poverty through International Development
  • Increase Sustainability through the use of Appropriate Technology
Appropedia follows an open design approach. Anyone can write or edit articles, anyone can plant the seed of an idea and any group can use these pages to work collaboratively, all to further the success in our global initiatives. Others will build onto the ideas, contribute to the work or get inspired to create something new altogether. Which of your ideas, projects or current works would you like to add? Would you like to help in our exciting project of porting valuable information from other sites (with permission of course)? The table below has some ideas for contributors. We invite you to start today.

Or perhaps you came here in search of information. The material on this site is here free (as in speech) for your use! Use the search box at left, click on one of the categories in the table below, or browse all categories and all 10,303 articles. If you don't find what you're looking for, please let us know on our Requested content page. We value your feedback.
