Knowledge in the hands of the people

Knowledge in the hands of the people In a meeting for the 30 years of Grupo Sofonías, a draft about the philosophy of the EcoSur Newtork was made, based in the principles of the open source code:
  • Knowledge must be available in a free manner
  • The tools to develop and apply that knowledge must be available in the local language
  • People must be able to modify and inprove that knowledge as they needed
  • Any modification or improvement to that knowledge must be returned to the community

As a result of this first draft, the EcoSur Network embraced at the begining of 2010 the license Creative Commons V.3: Attribution-NonCommercial-ShareAlike 3.0 Unported.

In 2005, SofoNic has started a dual education program for masons in Nicaragua, using its house-building programs as a base. Teaming up with the local technical school in Jinotepe they are graduating about ten masons every year since. Most f them have found jobs in construction or have started a business on their own. SofoNic has contracted several of them as master masons in the reconstruction programs in Haiti.
