English to Dutch Social Sciences Government / Politics

All right, I'm just going to throw it out there: advocacy. To translate or not to translate. I can think of pleitbezorging, but shouldn't advocay be in the VanDale by now? I'm talking about the use of the word in documents relating to NGO's and development work. A few examples below.

1) through innovative interventions that promote medicines policy advocacy

2) access to and the rational use of essential medicines and capacity building of an advocacy voice for needs driven drug policies

3) will provide advocacy and capacity building to developing country partners
