Policies are far from being monolithic blocks that stand by themselves and can be neatly separated, replaced or reformed. Rather, they are interlinked and often the success or failure of one policy depends on other, related policies. At the same time, as a result of the multilevel, complex and interdependent nature of policy issues, as well as the spread of new forms of governance that emphasize collaboration – networks, partnerships and alliances– a comprehensive understanding of the policy landscape has become paramount.
