Understanding Complexity, Interpreting Change, Creating Opportunities
Trends and Visions for Water Landscapes in Transition

29 Agosto, 2026

In ensuring continuity with the long editorial history of PORTUS – which, after reaching the prestigious milestone of 50 issues celebrated with a special edition, confirms its status as a global benchmark observatory – starting from this issue, I assume the editorship of the journal, which encapsulates its founding core in the relationship between city and port and the redevelopment of urban waterfronts.

I welcome this new appointment with a profound sense of responsibility to preserve its identity, but also with the determination to project it towards the complex challenges and opportunities that currently affect the contemporary waterfront landscape. I bring with me a valuable wealth of passion and a clear vision, along with the emotion of looking back at a history I feel is deeply shared.

My journey with the journal has well-established roots: since 2013, in the role of Editorial Coordinator, I have had the privilege of closely following its strategic transition from the historic printed format to the current digital platform, overseeing its production and supporting, day after day, the achievements attained together with the entire scientific and professional community that animates and enhances its evolution.

Taking up the baton from my esteemed predecessors – Joan Alemany, Rinio Bruttomesso, and José Luis Estrada – means choosing to proceed in the spirit of a grateful and dynamic continuity. While preserving the editorial line traced over these years, PORTUS has never replicated static models or adopted preconceived approaches. Rather, it has always been capable of embracing the most authentic lesson of liquid territories: the ability to constantly change and renew itself to interpret the flows and transformations of time, discovering issue after issue the vulnerability and value of the land-water interface, as well as the complexity of port-city relations and the opportunities generated by a governance capable of guiding them. Research and dissemination have thus formed the pillars of this journey, founded on the invaluable exchange of experiences and ideas with authoritative experts, scholars, and professionals of international standing.

The wealth of knowledge and experience built by RETE and PORTUS over more than two decades remains a steadfast compass. From here, the history of the journal continues with the same curious and visionary attitude, looking toward the future with new eyes to explore unprecedented horizons.

Ensuring continuity also means knowing how to evolve to respond to the challenges of our time. In this new phase, the journal intends to promote an expansion of perspectives, while simultaneously bringing a renewed focus on the dynamics, projects, and processes shaping the waterfront. The goal is not to diminish the fundamental value attributed over the years to the various aspects related to port-city relations, but to recognize that this interaction – whether driven by synergies or marked by conflicts – always materializes in the physical space of the land-water interface. An arena in which design and research must interpret, at various scales, the most advanced trends in the global debate: from regenerative coastal planning to Nature-based Solutions, from the energy transition of port infrastructures to the role of urban contexts as digital hubs for the development of the circular economy, and from the predictive potential of the digital twin to the new frontiers of the blue economy.

Understanding the complexity of the challenges and opportunities brought into play by spatial redevelopment, socio-economic development, and technological innovation on the waterfront – by adopting a holistic and transdisciplinary approach – today constitutes the essential cornerstone for steering these dynamics. In this perspective, the integration of ESG criteria becomes the ideal framework within which to implement the ecological transition, resilience, and digitalization, ultimately redefining the future of specific waterfront contexts, whether urban or port-related.

Upon this editorial line, and with its gaze turned toward the international context, the new course of the journal takes shape, aiming to consolidate its role as an observatory and space of inquiry into the evolutionary dynamics of water landscapes, understood in their broadest sense, as complex systems where physical, ecological, cultural, and socio-economic dimensions converge.

In concluding this editorial, I wish to express my deepest gratitude to the President of RETE, Teófila Martínez, the Vice Presidents, and all the members of the Management Board for the trust placed in me by appointing me to the editorship of PORTUS, giving continuity to a journey that began several years ago. A sincere thank you, filled with esteem and profound affection, goes to the authoritative directors who preceded me, irreplaceable points of reference: the founders Rinio Bruttomesso and Joan Alemany – with whom I had the privilege of sharing, from the very beginning, the passion and vibrant day-to-day life of my editorial experience – and the outgoing director José Luis Estrada – with whom I was fortunate to share the stimulating journey of growth over recent years, in a constant, sincere harmony of views and invaluable exchange.

My thanks also go to the community of authors, reviewers, and readers who continue to make RETE’s editorial products a privileged observatory on the dynamics and perspectives of port cities and urban waterfronts.

Finally, an affectionate and special thought goes to my colleagues and to all my friends in Venice: precious traveling companions during intense workdays, in the sharing of common passions and new experiences, and in the profound value of the time spent together. An invisible thread binds me to them, crossing both time and space.

To everyone, I wish a stimulating and rewarding reading experience.

PORTUS 51 | Launching “Archipelago”

Concretely inaugurating the new perspective of inquiry of PORTUS is the inclusion, starting from this issue, of an unprecedented component within the magazine’s structure: the “ARCHIPELAGO” section. This new editorial space is born with the ambition of serving as an observatory on contemporary water landscapes, understood in their broadest and most interdisciplinary sense. Oriented toward analyzing complexity, as well as mapping and interpreting the multi-scale strategies that are reshaping waterfronts, this section is structured into a mosaic of case studies, ideas, and visions, with the aim of representing the heterogeneity of experiences on the international context and reflecting the plurality of approaches shaping the future of these territories.

The choice of the archipelago metaphor responds to a precise descriptive logic. On one hand, it reflects the identity of PORTUS’s scientific and professional community: a network of experts, professionals, and researchers who are geographically distributed and possess multidisciplinary expertise, bridging design culture with social and environmental sciences, and governance with economic and management dynamics. On the other hand, within this same framework, the individual territorial experiences, projects, and case studies described in the various contributions (articles, interviews, insights, and reports) represent autonomous “islands” of knowledge and expertise, where the complementary perspectives of architecture and engineering, economics, ecology, geography, and spatial planning converge. While maintaining their own specificity and identity in terms of geography, scale, resources, tools, and actors involved, these realities often share the same development challenges and opportunities. Their deep bond lies in belonging to the same “archipelago“: a shared water landscape that surrounds them, connects them, and defines their horizon of reference – whether a maritime waterfront or a riverfront, an urban context or a port area.

This matrix of investigation constitutes the core around which the section intends to collect, present and disseminate the results of empirical fieldwork, through virtuous models, replicable practices, and solutions oriented toward sustainability, digital innovation, and resilience. To these are added the outcomes of theoretical and methodological advancement applied to governance, planning, and design, as well as to investment strategies and dynamics of social reclamation.

The different experiences represented, as independent elements that fit into a scenario strongly characterized by the element of water, contribute – also through the voices and expertise of their protagonists – a distinctive design sensitivity and a context-specific strategic vision to a global framework in constant evolution. The section aims to bring plural approaches and diverse perspectives, contextualizing them within the international scenario, so as to provide a mapping, as well as an interpretation, that connects governance practices and development plans with territorial value creation, investment flows and socio-economic dynamics..

Within this framework, diverse expertise and specialized perspectives connecting institutions, research, and management meet to decode complexity and explore the windows of opportunity of contemporary waterfronts, projecting specific field projects and management models toward new development scenarios.

PORTUS 51 | In this Issue

Sharing a comprehensive wealth of tools, interpretive frameworks, field data, and operational solutions – in full continuity with the vocation that the journal has always pursued over these years – contributes to stimulating critical reflection, advancing knowledge, and consolidating international exchange.

Consistent with this approach, the ARCHIPELAGO section debuts in this issue with a double interview-dialogue featuring Arnoud Molenaar (Global Director of Resilience and Partnerships at Square Floating City, former Chief Resilience Officer of Rotterdam) and architect Richard Coutts (Founder of BACA Architects FRIBA). This dialogue analyzes the challenges and opportunities of climate architecture, proposing modular and scalable floating neighborhoods as an ecological, safe, and reversible solution, serving as an alternative to defensive design based on rigid barriers and traditional coastal overdevelopment. The two experts analyze various aspects related to marine expansion driven by the principle of livability, capable of mitigating sea-level rise and responding to land scarcity, thereby making waterfront territories more resilient without sacrificing urban quality.

The contribution by Stephen Haynes (Executive Director of Growth and Prosperity at Southampton City Council) is dedicated to the Southampton Renaissance Vision (2025), an urban study demonstrating how a major maritime city can regenerate its waterfront without altering its industrial core or compromising its productivity. Through targeted interventions in historic areas and piers (West Bay, Town Quay, Mayflower Park, Ocean Village), Southampton repositions the waterline and port quays as accessible public infrastructures integrated into the urban fabric, combining quay electrification with the historic geothermal district heating network (Southampton District Energy Scheme).

Authored by planner and urban designer David Grant (Glasgow City Council), the article on the regeneration of the Clyde Riverfront retraces the long-term regeneration process and illustrates a series of pilot interventions aimed at reconnecting local communities to a continuous, flood-resilient, and inclusive “River Park.” Among these are the North Laurieston master plan, the restoration of the historic Govan Graving Docks, and the activation of Custom House Quay – a trial for the innovative application of feminist town planning guidelines.

Architect Fred Holt (Partner and Director of 3XN Australia) illustrates the New Sydney Fish Market project at Blackwattle Bay, inaugurated at the beginning of 2026 and winner of the Special Jury Award at MIPIM 2026 as an admirable example of coexistence between maritime industry and public space. Beneath a monumental undulating roof made of glued-laminated timber, equipped with solar panels and closed-loop water recovery systems, the still-operational fish market and other commercial activities are integrated across vertically separated flows, becoming a main attraction of the new waterfront square.

Architect Xinyan Xu (Aedas) presents the master plan for the former Guangzhou Shipyard in the Liwan District, configured as a “Central Activity Zone – Digital Future Port,” integrating industrial archaeology with Transit-Oriented Development (TOD) principles. The project enhances the ancient dry dock by converting it into an underground museum connected to sunken plazas, organizes the mixed-use functionality of the linear park (2 km) while preserving historic gantry cranes and slipways, and aligns commercial expansion with a multi-level mobility network where each lot is accessible via 15-minute pedestrian pathways.

Engineer Tytti Sirola (CEO and Co-Founder of Bluet Floating Solutions) offers an interesting perspective on modular floating infrastructure as a response to land scarcity and climate adaptation. Her contribution maps the evolution of prototypes and completed solutions, particularly along Northern European waterfronts – including the Vök Baths in Iceland, the Panko Sauna-lounge in Finland, and the Elite Marina Tower in Sweden – emphasizing how stability, modularity, and safety can be tailored to meet specific needs, delivering design solutions capable of adapting to diverse contexts and landscapes.

Last but not least, the contribution by architect Gilles Hasbroucq (Archipelago Architects) focuses on the new hotel and residential complex adjacent to the canal-port of Calais and Fort Risban, which, in restoring new spaces for public use to residents and tourists, translates the coastal physiognomy through the architectural metaphor of “sails.” The project – under construction in 2026 with a completion horizon between 2028 and 2029 – is developed through a public-private partnership and stands as the final piece of the “Calais la Plage” master plan. Within this framework, it acts as a filter between the macro-logistics of ferries and the urban scale of the beach, adopting a rigorous low-carbon strategy based on thalassothermal heating and the integration of photovoltaic modules.

Alongside this important innovation, the main body of the journal is structured, as usual, around its historic sections, offering a multidisciplinary and organized framework of port-city relations.

The REPORT section delivers the outcomes of the third edition of the prestigious summer course “Puertos comprometidos con sus ciudades: transición energética, digitalización y transformación urbana”, promoted by RETE and the Cátedra Puerto de Sevilla – Universidad de Sevilla at the historic venue of the Universidad Internacional de Andalucía (UNIA) de La Rábida in Huelva.

Coordinated by Rafael Carmona Ruiz (President of the Port Authority of Seville and Associate Professor of Business Administration at the University of Seville), the section is organized into four essays summarizing the topics presented during the event’s sessions. The articles delve into various aspects that emerged from the multidisciplinary debate, which featured key stakeholders and industry experts exchanging views on energy transition and digital innovation as strategic levers to redefine the port-city interface through a sustainable lens.

The contribution by Pedro Baena-Luna and Baldomero Ortega Pardal investigates the convergence between Smart Cities and Smart Ports, proposing an integrated “smart territory” model; in this approach, collaborative governance proves superior to technological implementation in promoting innovation and urban resilience, while data enhancement emerges as a true strategic asset.

Following this, the topic of the social value of cruise tourism is developed by Carolina Ruiz-Moreno and M. Ángeles Rodríguez-Serrano through the combined application of the SPOLY and SROI methodological models to Andalusian ports, aiming to evaluate the real well-being returned by the sector to local communities and to provide new strategic management tools to optimize public policies.

José Luis Galán-González, Carolina Ruiz-Moreno, and Paula Villalba-Ríos examine in their article the technological pathways toward the Net-Zero 2050 goal, utilizing the Port of Huelva as an excellent case study and a benchmark energy hub in the European context for the production and export of clean carriers.

Finally, the essay edited by José Luis Galán-González interprets the energy transition as a driver for the strategic redefinition of port planning in light of the Marco Estratégico of the Spanish port system. The author examines quay electrification through the deployment of Onshore Power Supply (OPS) systems, demonstrating how shore power access and flexible grid management constitute the new frontier of territorial value and waterfront urban regeneration.

The PORTRAIT section of this edition is dedicated to the port city of Palermo, a context that has experienced an extraordinary urban, logistical, and cultural regeneration over the years. In this editorial project, it is captured as a laboratory in full and fervent evolution, capable of redefining the land-water interface through a multi-scale and multi-governance strategy.

On a personal note, I am particularly enthusiastic about dedicating this editorial project to the Sicilian capital. In 2006, I had the opportunity to take part in the special “City-Port” section of the 10th International Architecture Exhibition of La Biennale di Venezia. Conceived and curated by architect Rinio Bruttomesso, it was staged outside the Lagoon for the first time and found its ideal exhibition setting precisely in Palermo, organized into widespread itineraries and exhibitions hosted in some of the city’s most prestigious and evocative venues.

Designed to map out an unprecedented vision of port cities, the event cast a spotlight on Italy and Palermo while looking at international experiences, at a historical moment when the city-port relationship was emerging as a strategic issue both for the development of the maritime economy and for the balanced growth of the urban fabric.

During the same period the city of Palermo was engaged in an open and courageous debate on the future of its waterfront. Among the key figures was Professor Maurizio Carta, whom I had the opportunity to meet on that very occasion and whose insights played a crucial role not only in initiating but also in guiding the evolution of the metamorphosis of Palermo’s coastline.

Seeing today, two decades later, how those initial insights have translated into consolidated dynamics, successful implementations, and mature visions not only arouses a sincere emotion but stands as tangible evidence of the value that research, forward-thinking governance, and international exchange can generate at the land-water interface.

The PORTRAIT thus unfolds starting from the Presentation authored by the coordinators Maurizio Carta, Barbara Lino, and Daniele Ronsivalle, which clearly reflects the editorial choice to work through intersections and blending, capturing the complexity of the Palermo waterfront metamorphosis between identity and design, memory and vision. The concept of “liquidity” and “porosity” is outlined by Maurizio Carta in the Introduction where, interpreting the coast as the city’s new linear and strategic cardo – a generative axis connecting a revitalized “archipelago of places,” cultural contexts, and art foundations – he addresses water not only as a maritime horizon but as a climate and resource resilience challenge.

The institutional narrative takes shape through Interviews with Mayor Roberto Lagalla and the President of the Port Network Authority (AdSP) Annalisa Tardino, who demonstrate a strong understanding aimed at consolidating and improving the port-city relations built over time. Emphasizing the importance of capitalizing on the successes that have restored international competitiveness to the port of Palermo, as well as to the port network of Western Sicily, is Pasqualino Monti (former President of the AdSP and extraordinary Commissioner for the revitalization of shipbuilding and the port-city interface); in his essay, he retraces the strategies and projects that have characterized the rebirth of recent decades. Meanwhile, Giuseppina Leone (President of the Chamber of Architects of Palermo) examines governance and implementation tools, emphasizing the relevance of a strong public leadership capable of transforming a simple “sum of projects” into a true “city project.”

The design core and urban evolution of the city-port interface are examined in detail in the section Planning, Building and Living the Port-City Space. In particular, Maurizio Carta, Barbara Lino, and Cosimo Camarda reconstruct the twenty-year urban planning history from the 2008 Port Master Plan to the tangible reclaiming of public space along the waterfront. Daniele Ronsivalle and Annalisa Contato analyze the System Strategic Planning Document (DPSS) as an innovative tool for developing network economies and Euro-Mediterranean territorial balances.

The architectural choices of the Palermo Marina Yachting at the Trapezoidal Pier are illustrated by two designers: Sebastiano Provenzano describes its mixed-use functionality and the articulated formal layout that reveals the memory of the ancient Castello a Mare through the new urban lake; Emanuela Valle illustrates the design concept of the city-port interface along Via Crispi, a spatial device conceived as a three-level “habitable threshold” that dismantles the old physical and visual barrier.

The perspective on management and entrepreneurial opportunities is entrusted to Antonio Di Monte (Palermo Marina Yachting), who describes the economic impact of high-end yachting and superyachts on the territory, and to Donato Didonna (Pier 38/Gambero Rosso Academy), who reflects on the foresight of entrepreneurial risk and the ability to “see what is not there.”

Directors and officials from the AdSP and the Municipality – Enrico Petralia, Cosimo Camarda, and Adriano Di Francisca – illustrate the value of international design competitions, delving into both the call for the elevated pedestrian connection system over Via Crispi and the one for the landscape reconfiguration of the Foro Italico, Sant’Erasmo, and the mouth of the Oreto River.

The narrative then shifts toward the recovery of industrial archaeology and the regeneration of seaside villages with contributions from architect Paolo Porretto and the Regional Director of the State Property Agency Silvano Arcamone. They analyze the extraordinary value of the former Chimica Arenella, currently at the center of the international Reinventing Cities (C40) program for a zero-emission conversion capable of redefining the coastal landscape and its tangible and intangible heritage. Alessandra Badami examines the southern coastline and the mouth of the Oreto River, presenting the participatory urban planning project Mare Muto. The initiative stands as a strategic tool to rebuild coastal identity and encourage public enjoyment of these spaces, also through the involvement of younger generations. Collector Massimo Valsecchi, in a dense dialogue with Maurizio Carta, describes the Palazzo Butera Foundation as a “contemporary Renaissance workshop,” a porous membrane open to the city that reconnects the sea to the historical memory and civic identity of the Kalsa district. The historical essay by Antonietta Iolanda Lima offers a critical interpretation of the symbiotic relationship and complex dialectic between Palermo and its sea, retracing past points of friction, morphological alterations, and urban fractures, up to examining the legacy of Italo Rota’s Parco Prato and the creative language of recent regeneration interventions.

The section Governance, Management, Economy and Harbour Space demonstrates how the quality of urban space is intrinsically linked to economic dynamics, public policies, and private investments. Within this framework, the investigations by Risposte Turismo presented by Francesco Di Cesare and Anthony La Salandra quantify the macroeconomic relevance of maritime tourism in Palermo. Matteo Catani (GNV) and Leonardo Massa (MSC Cruises) offer the perspective of major shipping and Blue Economy players, highlighting, on one hand, the strategic role of ferries for territorial continuity and the support of regional production systems, and, on the other hand, the impact of cruise tourism as a driver for counter-seasonality and the continuity of flows. The vision of Roberto Perocchio (Assomarinas) interprets yachting and tourist ports as an ecosystem of excellence experiencing a strong recovery, capable of generating new models of urban regeneration which, by integrating innovative technologies and intercepting the strategic routes of elite yachting, produce significant impacts on the territory.

The section Port-City Mindset: Communities, Value and Culture shifts the focus toward the civic and social dimension of regeneration. In her essay, Antonella Filippi describes the narrative experiment aimed at giving a direct voice to the port and capturing the collective perception of its changes. The experience of the Ecomuseo Urbano Mare Memoria Viva is reflected in the account by Cristina Alga, which shows how collective memory and the enhancement of intangible heritage constitute fundamental safeguards for community care and the activation of social participation. Meanwhile, Tiziano Di Cara retraces the evolution from the artistic installation of the Nautoscopio to the creation of Nauto and Nauto Park, demonstrating how public art and cultural entrepreneurship are capable of reactivating community relations, transforming fragile locations into desirable spaces.

Finally, the section Port-City in Images reminds us that every port city is also a water landscape in perpetual evolution. The invaluable photographic research of Sandro Scalia does not merely document temporal stratifications: it constructs a gaze, makes permanences legible, registers discontinuities, and restores that perceptual dimension that often eludes the tools of urban planning and design.

Traditionally dedicated to projects and initiatives promoted by RETE Members, the FOCUS section proposes in this issue two excellent case studies currently in an advanced phase of construction. Jesús de Sobrino Grosso (De Sobrino & Asociados) describes the transformation of the Muelle Ciudad in Cádiz, the first tangible piece of a broader port-city integration strategy. Guided by the experience of the President of the Port Authority Teófila Martínez, the work redevelops a strategic area of 22,500 square meters, transforming it into a public, pedestrian, and multifunctional space that extends the historic center toward the sea, allowing cruise quays and daily life to coexist.

With a complementary perspective focused on territorial competitiveness, Teresa Cardoso, President of the Administration of the Port of Aveiro, outlines its role as a logistical hub serving the internationalization of the regional economy. The contribution illustrates the modernization strategy of the port, which ranges from the new railway terminal to the digitalization of services, up to the sustainable transition driven by the collaborative governance of the Port Community Association, taken as the true differentiating factor for the development of the port system.

The LIGHTHOUSE section, featuring collaborations from some of the benchmark figures within our community of scholars and professionals, hosts four contributions of international scope: Alessandra Badami and Ester Badami retrace the metamorphosis of Bristol’s Harbourside, which has become a vibrant cultural and creative district; Roberto Converti introduces the study “Ciudades a prueba de futuro. Fortalecer la resiliencia ante desastres” published by the IDB (Inter-American Development Bank) and dedicated to urban resilience and coastal risk management in Latin America and the Caribbean; Marta Moretti analyzes the necessity of an integrated multi-port system for the Northern Adriatic, which emerged during the conference “Porti, interporti e corridoi. Venezia e l’Alto Adriatico come porta dei traffici verso l’Est” during the 2026 edition of the Venice Boat Show; Roger Ríos Duarte examines – through the cases of Panama, Honduras, and Costa Rica – Central American city-port interface models, emphasizing the need to move beyond traditional European interpretive frameworks when facing Latin American logistical asymmetries.


In concluding the presentation of this edition, I wish to express my hope that PORTUS will continue to consolidate its role as a dynamic platform for reflection and exchange for the scientific and professional community, confirming its status as an indispensable space of convergence for research and the definition of new scenarios within the international context.
