Despite its relatively small size, Slovenia is a good illustration of the potential of regional development policy. Its internal diversity, openness and experience of rapid structural change all reinforce the need for efficient reallocation of resources, while underscoring the need to take account of the potential positive and negative externalities associated with the shifting structure of economic activity. With 36% of the national territory falling under Natura 2000 protection, spatial planning is particularly challenging and yet also particularly important. Given the absence of a regional tier of government and the extreme fragmentation of the municipal level of authority, Slovenia needs to develop capacity at intermediate levels, to address policy problems that are best tackled at a scale in between the local and the national.
