For example, the lead within the UN system for action and thinking in this area was given to UNDP and it has offered guidance to its staff and governments on what was then called institution building since the early 1970s. This involved building up the ability of basic national organizations, in areas such as civil aviation, meteorology, agriculture, health, nutrition to do their tasks well. All UN specialized agencies were supposed to be active in support of capacity building in the areas for which they were technically qualified e.g. FAO for the rural sector and agriculture, WHO for health etc., but they achieved mixed results. USAID UK/DFID and some of the Nordic donors were also active in the area, as were some of the Soviet bloc countries, but the success of their efforts were affected by the perception that national political interests motivated their efforts.
