If you would like to keep an eye on training events being held in your country, this is a good place to look. I noticed that in December 2011 there will be workshops on:
Ghana: Research writing skills, Journals online, Monitoring and evaluation of information projects, products and services; Ethiopia: Science into policy; Tanzania: Web 2.0
Workshops do not seem to be advertised very far in advance, so it is worth looking frequently if you want to see what is available. To make it easy you can search by country.
On the other hand if you want to run your own workshop, training workshop programmes and associated material are available for download from INASP
