However, 29% of the respondents didn’t know whether respective activities or initiatives have taken place, while others suggested that activities to implement the Strategic Plan or revise NBSAPs did not help to increase cooperation. Identifying synergies and overlaps among conventions at national level could thus foster the operationalization of the conventions at the sub-national level - in particular in case of limited resources. Several case studies will be presented here that illustrate the variety of approaches taken by countries, reflecting national circumstances and, in particular, the institutional environment. The case studies highlight outcomes deriving from synergistic approaches and the extent to which particular objectives and activities related to the other Biodiversity-related Conventions (other than CBD) have been addressed in finalized NBSAPs.
