  Five Norwegian research institutes (NGI, AHO, NIKU, NTNU, and NORCE), representing diverse academic disciplines such as risk management, landscape architecture, design, heritage, ecology, and earth systems science, have collaborated in multidisciplinary teams. Using system-oriented design processes, these teams work alongside local communities to mitigate hazard risks. The NATURACT research aims to develop landscape-based transition plans utilising Nature-Based Solutions (NBS) to adapt to and mitigate climate-induced hazards. At the midpoint of this research, preliminary findings suggest the approach serves as a model for Regenerative Landscape Design. This integrative process provides a framework for sustainable, long-term hazard mitigation planning, grounded in landscape-based perspectives that facilitate spatial connectivity, soil understanding, and crosssectoral collaboration.

  As President of the European Council of Landscape Architecture Schools (ECLAS) it is my great pleasure to introduce these selected proceedings of the ECLAS Conference 2024, hosted at the Université Libre de Bruxelles (ULB) in Brussels. The conference theme, Regenerative Landscapes – Designing the Transition, has underscored the critical role of landscape architecture in navigating the complexities of climate change, biodiversity loss, and societal transformation. We have gathered with almost 300 people in Brussels at a pivotal moment. Our landscapes -both urban and rural- are under unprecedented pressure, with six of nine planetary boundaries already exceeded. This conference provided an opportunity to reimagine landscapes not merely as spaces of adaptation but as active agents of regeneration. The contributions in this volume reflect a shared commitment to fostering landscapes that restore ecological function, enhance social equity, and inspire cultural renewal. Our thematic tracks have explored the diverse facets of regeneration: from energy and mobility landscapes to foodscapes, hidden landscapes of the global value chain, biodiversity regeneration and democratic landscape transformation. Each theme represents a vital component of the transition towards resilient, equitable, and thriving landscapes. The discussions initiated here will be crucial in shaping the future of landscape education, research, and practice. I extend my sincere gratitude to the organising team, our hosts at ULB and CIVA Brussels, and the dedicated researchers, educators, and practitioners contributing to this conference. Further, the conference and these proceedings would not have been possible without the TELOS ERASMUS project and its team. TELOS provided the conceptual framework for designing our call for papers guiding the discourse of this conference. I hope that our 2024 gathering has served as a catalyst for new collaborations and bold ideas, driving the discipline of landscape architecture toward a regenerative future. Dr. Ellen Fetzer ECLAS President 2018-2024 European Council of Landscape Architecture Schools.

• Müller, Sabine & Sjödahl, Elisabeth Ulrika (2025). HYDROPOLIS: ENVISIONING WATERSHED URBANITY. Full text in Research Archive Show summary

  Contemporary cities grapple with detachment from their hydrological environments, exemplified by the Oslo region, which faces challenges of water excess and scarcity amid climate extremes. The Oslo Hydropolis project has emerged to explore regenerative water management in relation to urban life over nearly a decade. Hydropolis aims to complement contemporary urban planning and design with an approach termed "Watershed Urbanity," which views catchments as socio-ecological units. This concept seeks to reintegrate the social and cultural significance of water, moving beyond the perception of water as a mere risk or resource. The project's outcomes reveal the potential to reimagine the Oslo region through the lens of its watersheds. Here, the dynamics of water flows—both qualitative and quantitative— land management and daily practices are inextricably linked. By promoting water as an active agent to shape social practices and vice versa, the vision pioneers a participative and bodily outdoor urbanity in already developed areas and advocates for regenerative frameworks in development sites. Examples include daylighting small streams to promote bodily experiences of bathing, enhancing rural water through run-off filter spaces for day-out activities, and establishing decentralized water supply systems that create communal spaces around water sources and ensure public access to the fjord. Additionally, the project creatively engages with elements of landscape heritage, such as ice ponds, rehabilitating them into pools and bogs that include outdoor spaces fostering multicultural community interactions. Furthermore, the project promotes the role of low-density communities as stewards of well-moistened soils, and positions logistic parks as facilitators for groundwater replenishment. Although the project’s speculative nature may limit immediate applications, its compelling visual outcomes underscore the relationships between territory, water, and social interactions. Hydropolis aspires to ignite discussions about incorporating watershed logic into urban design, and more so propels a regional urbanity as a driver towards water regeneration, offering adaptable methodologies for other metropolitan areas.

  Beyond surface What do we actually know about the ground on which we stand, and how does it relate to our landscape projects? Our perception and understanding of our surroundings supply the framework for how we think and work. The notion of the ‘deep landscape’ was formulated with the aim of bringing awareness to an otherwise overlooked relationship between the ground, water and huma

  We know very little about what is under our feet. We are used to the sight of manhole covers punctuating the streets around us, and we know that they provide access to the subterranean water system. But where does that system start and end, and how is the manmade, reworked ground made up? Humans have a history of adapting well to notions of an expanding world, but what about the closest realm in distance and time: the ground on which we stand and within which our fresh water is contained? This thesis argues in favour of urbanism not only incorporating landscape but also actively incorporating the other, unseen half of the landscape: the underground. It explores how we could get closer to perceiving the depth of the landscape setting we inhabit. This is increasingly important in a time when human actions dominate the geological ground conditions. The design case of daylighting of a piped underground water system to make it an open, landscape-integrated surface system reveals a need to design both visible- and invisible underground landscapes together. This exegesis thus expands on my claim that the landscape has a composed depth. The design case has been used to test this assumption and provided various findings, reflected on a posteriori in the exegesis to determine their implications for the landscape- and urbanism disciplines. This has further resulted in the coining of the ‘deep landscape’ as a term, a concept, and a strategy for design. This thesis is positioned between the fields of landscape architecture and urbanism, and it offers insights into water and urban ground conditions in one conference paper and two published articles. It uses the term ‘deep landscape’ as a reminder of the inseparable context beneath our feet. The presence of water and the ongoing processes below grade, as well as the subterranean landscape modified by humans and its installations, the reworked ground, must inform and become part of landscape architecture and urbanism.
