Throughout history, Paris has always been a city of walls. The differences between the wealthy core and the poor periphery are increasing rapidly. The Boulevard Périphérique, Paris’s concrete ring road, is the spatial and symbolic manifestation of the imbalance between the city and periphery. The ring road works as a mobility bottleneck at the regional scale, while locally it strengthens the perception of urban inequality by complicating access to the resources of the city centre. Transforming this infrastructure element does not involve only spatial and functional restructuring, but also interventions at the social and governance level. This research and design project shows how the redevelopment of the Boulevard Périphérique can contribute to transform its spatial, functional, social and symbolic roles, in order to address the socio-spatial inequality challenges in the metropolitan area of Paris. A strategy for the redevelopment of the ring road is proposed, accompanied by spatial interventions and planning guidelines. The main outcomes are a strategic- and spatial framework that function as a toolbox for the redevelopment project. This toolbox consists of three important components: structural conditions, contextual needs and intervention possibilities.

Economy and technological innovation have always shaped the Dutch landscape and society. The evolution of the Internet has led to a new economy based on digital information and communication. New production, consumption and business models are mushrooming, especially in the Province of South-Holland. This fast development is facilitated by the massive exploitation of construction materials, energy and data flows. The data sector has a high energy demand, which is even surpassing the CO2-emission of the aviation and shipping industry. The flows that support the sector are linear, consuming a lot of energy and producing a lot of waste, because construction materials and infrastructures have a short life-span. The Province of South-Holland aims to be circular in 2050. Thus, addressing the challenges that this new economy poses on the region need to be prioritized. The strategic and integrated development of the digital economy into the (urban) fabric of South-Holland functions as a catalyst for the circular Province. The goal will be reached by proposing a strategy consisting of a spatial development framework, stakeholder action plan, phasing and scenarios, policy guidelines and a typology toolbox. This strategic report explores how a connected and resilient datascape in South-Holland can be created/developed while preserving the global value and increasing the local value. For the strategic and integrated development of the digital economy into the (urban) fabric of South-Holland, data hubs as a platform for awareness, participation and knowledge exchange are proposed. These platforms will either function as a creator or a transformer of the local environment, while preserving the global position of the region. The development of these datascapes is circular, (energy-) efficient and creates value throughout the different scales. This will form the base of a sustainable and resilient circular economy in the Province. In this strategy, the flows of construction materials, energy and data are optimized from linear flows to circular cycles.
