In addition, less than 40 per cent of such plans, and in some cases less than 20 percent, address different sorts of constraints such as in the areas of skills, environmental impacts or sources of finance. However, if these plans do capture the level of governments’ commitment to infrastructure planning and development, then considerably more work is needed, for both more robust national infrastructure and development strategies, to ensure infrastructure development does play the fundamental role it can have in transforming developing economies. In part, that is because the mixture of creative and destructive forces accompanying such a transformation do not automatically translate into a virtuous growth circle while the rents that are inevitably created in the process can be captured by a privileged group in ways that clog the economic arteries and increase the dangers of a political stroke.
