 Tony Hill, former head of Office in Geneva, described a "second generation" of UN-NGOs relations.This generation "is marked by the much larger scale of the NGO presence across the UN system, the more diverse institutional character of the organizations involved, now including national, regional and international NGOs, networks, coalitions and alliances, and the greater diversity of the issues that NGOs seek to address at the UN.Above all, the second generation of UN-NGOs relations are essentially political and reflect the motivation of NGOs to engage with the UN as part of the institutional architecture of global governance."
