Welcome to AIDG.net, the Appropriate Infrastructure Development Group's online appropriate technology library. Here you will find information on appropriate technologies ranging from biodigesters and ram pumps to windmills and hydroelectric systems.

We are currently in the process of updating the site and increasing the content. We have just added a section for documents produced by the AIDG Technology R&D program which we will be populating over the next few months. We will also be updating the third party references with references that we have used in recent projects. Please follow our blog at http://www.aidg.org/blog for news on updates.
