Overcoming this mismatch requires coordination between typically fragmented government agencies—and this coordination requires inter-organizational collaboration. In Portugal, the twin challenges of declining urban centers and sprawling suburbs, combined with the absence of a metropolitan planning structure, have heightened the importance of inter-agency collaboration, especially in terms of land use and transportation. In contrast to typical studies of policy integration, which tend to focus on barriers to collaboration, in this thesis I examine forces which contribute to its emergence. I consider two questions: first, what conditions and factors have actually led to inter-organizational collaboration in the Portuguese context? Second, what is the potential for a particular scenario-building process to lead to further collaboration among those who participated? Study of existing collaborative arrangements reveals five conditions which appear to contribute to the emergence of collaboration. A qualitative and quantitative analysis of scenario-building workshops conducted with stakeholders in Portugal suggests that these exercises have increased the likelihood of the future collaboration among participants to a small degree. Finally, recognizing that collaboration is necessary, but not sufficient, for better metropolitan-level development, I suggest ways in which government policy can take advantage of pro-collaboration forces.
