UNISDR has invested significant resources in the Staff development and training program. An important number of staff have made full and good use of these opportunities and positive feedback has been given. […] I emphasize that to offer the Skills Development workshops (Presentation, Facilitation, Communication, Management, Leadership, etc.) is a strategic objective for our organisation, and a response to your requests and expressed needs and verified by managers. I urge all Staff and all Supervisors not only to make the effort and take the time to follow these courses but to fully commit to carry through the program.

Margareta Wahlstrom, SRSG, UNISDR Geneva, May 2011

Content was very good. We addressed the issues we said we were going to address and then some more. I think we took it about as far as we reasonably could. […] I had high expectations and they were met!
