Hi Alwin - I know this thread has been continued offline, but I thought you might also like to try with Sonja Stojanovic of the Belgrade Centre for Security Policy. The Balkans has an extensive recent experience of DDR and Serbia is tackling the very issue of gender mainstreaming in the security sector right now. Good luck.
Hey Alwin, DCAF has just brought out a publication on linkages between DDR and SSR which includes country case studies. Each country case study also describes approaches to gender of DDR/SSR programmes in those selected countries (among other things). Might be interesting for you? Here's the link.
