Abstract

Urban area development in the Netherlands is increasingly characterised by fragmented landownership, inner-city transformation tasks and growing financial and procedural uncertainty. The literature points to a growing need for flexibility in area development, changing institutional circumstances and the increasing complexity of fragmented land ownership. At the same time, public and private parties remain dependent on each other to realise coherent and integrated area developments. This creates a growing need for lighter organisation structures and more flexible forms of Public-private Partnerships (PPP). However, knowledge about how these lighter forms of PPP are shaped in practice remains limited. This research examines how public and private parties shape lighter forms of PPP in Dutch urban area development. The study builds on institutional aspects and inter-organizational arrangements of PPP as theoretical framework to analyse how financial, legal, organisational and relational agreements are structured within this light public-private partnership. A qualitative multiple case study was conducted, consisting of seven Dutch urban area developments. Data was collected through semi-structured interviews with both public and private actors involved in the cases. The findings were analysed through cross-case comparison and validated through an expert panel. The results show that PPP light mainly emerges in situations where integrated implementation and coherent area development remain necessary. PPP light arises from the desire to maintain autonomy, the need for flexibility during long-term developments, limited municipal landownership, and situations in which full integration of land, risks and revenues is considered undesirable or unfeasible. In these situations, collaboration is formalised through agreements focused on shared area-wide challenges, while individual parties retain control over their own land positions, business cases and development pace. Recurring inter-organizational arrangements are reflected in agreements on cost-sharing, process coordination, flexible and jointly developed spatial frameworks, and a organised decision-making and consultation structures. Trust and communication prove essential in all forms of PPP, while PPP light can function as a vehicle to integrate relational aspects into all PPPs. PPP light exists in different gradations, ranging from limited coordination structures to more intensive forms of collaboration. PPP light distinguishes itself from traditional PPPs through individual land ownership and the absence of a joint legal entity or shareholder structure. It differs from incremental development collaboration (organische gebiedsontwikkeling) as the cooperation goes beyond one-to-one and solely cost recovery agreement that indicates exclusively public-private collaboration. The research contributes to academic knowledge on emerging of lighter organisation PPP forms within contemporary urban area development and provides practical insights into how partnerships can be organised under conditions of uncertainty, increasing complexity and fragmented landownership that parties do not wish to jointly exploit.
