Tracing the Roots of the Urban Forest as Forestscape in the Early Modern Period of Delft 1500-1800

Journal article (2025) - Erik de Jong, Rene van der Velde
This paper expands on the term ‘urban forest’ through spatial historical research and via the concept of Forestscape. The city of Delft in the western part of the Netherlands is taken as a case study, with the sixteenth, seventeenth, and eighteenth centuries as the sample period. Based on a methodology examining the spatial history of Delft from both a processes and a patterns perspective, we identify six tree planting practices or ‘afforestation events’. These plantings were integral to the early modern cityscape to the extent that the spaces in which they were planted were typologically incomplete without them. We identify tree plantings in group, line, and volume arrangements and posit these arrangements as a foundational scale in a multi-scalar understanding of the urban forest. The term ‘plantation’ formed the leitmotif for these plantings, interpreting natural features such as copses, groves, woods, and forests. The case study also demonstrates how, even in the early modern period, tree arrangements were established for a variety of benefits which ostensibly resonate with the contemporary notion of ‘ecosystem services’, but that were instead part of an alternative sensibility of what ‘city’ and ‘nature’ is. In this frame, the term Forestscape offers a way forward to retroactively interpret the historic urban forest and counter the current binary city-versus-nature discourse. We find that the collection of tree arrangements established in Delft in the period 1500–1800 presents a ‘wooded watermark’ of the city, which in many instances was reanimated with new tree plantings, demonstrating how parts of an urban forest can become a fixture in the morphology of the city and the lives of its citizens. At the regional scale, the extent of tree plantings around Delft with urban ‘roots’ extends far into the urban hinterland, while at the same time, trees and wooded areas with rural ‘roots’ extend well into the urban area. This condition opens a discussion on the inter-relationship between urban and rural realms and challenges the simplistic division between these two worlds apparent in contemporary spatial planning and design. ...

Renewables are key enablers in the plight to reduce greenhouse gas emissions and cope with anthropogenic global warming. The intermittent nature and limited storage capabilities of renewables culminate in new challenges that power system operators have to deal with in order to regulate power quality and ensure security of supply. At the same time, the increased availability of advanced automation and communication technologies provides new opportunities for the derivation of intelligent solutions to tackle the challenges. Previous work has shown various new methods of operating highly interconnected power grids, and their corresponding components, in a more effective way. As a consequence of these developments, the traditional power system is being transformed into a cyber-physical energy system, a smart grid. Previous and ongoing research have tended to mainly focus on how specific aspects of smart grids can be validated, but until there exists no integrated approach for the analysis and evaluation of complex cyber-physical systems configurations. This paper introduces integrated research infrastructure that provides methods and tools for validating smart grid systems in a holistic, cyber-physical manner. The corresponding concepts are currently being developed further in the European project ERIGrid. ...
