Inter-governmental organisations have deployed human rights field operations since the early 1990s. As of 2009, these operations are deployed across the world, most of them in conflict and post-conflict environments. Their staff plays a vital role in the protection and promotion of human rights, notably of the most vulnerable people. It is likely that the sector will continue to grow at a rapid pace. Much has been achieved in the brief history of this human rights field work and considerable strides have been made towards clarifying the applicable doctrine and methodologies. However, as with any sector, especially one so new, it is generally acknowledged that there remains considerable scope for development and improvement.
