Meresco - Knowledge Exchange

Meresco wishes to facilitate open knowledge exchange. Examples of initiatives contributing to this goal include Open Space conferences and a blog.

Meresco Open

Meresco Open is the open space conference for the community of Meresco and anyone interested. Users and contributors of Meresco share their knowledge and innovations between themselves and third parties. We meet several times a year. Each conference is centered around a particular theme.

For further explanation, the theme and the program of the previous Meresco Open, please visit the original invitation. You can find impressions of some of the participants (in Dutch) on the Meresco blog (see below).

The date of the next conference is not yet fixed. We will inform you on this site when the date is set. If you want more information about Meresco Open, please contact Hans Bakker at hans@seecr.nl.
