The term integrated conservation first entered the lexicon of urban heritage in the 1975 Council of Europe European Charter, recognising that the future of the architectural heritage depends on the weight attached to it within the framework of urban and regional planning. Since then, the agendas of sustainability, sustainable development and climate change have entered the debate, and various attempts have been made to re-position urban heritage from a specialist to a mainstream activity in the European context. In ‘The Geography of Urban Heritage’, we argued that the quantum of urban heritage recognised and appreciated today underscores a level of responsibility for the maintenance and processes of continuity whose realisation is beyond the scope and capacity of a specialist field. Additionally, that the complementary values of community, heritage, resource and usefulness, harnessed to common purpose, afford a potent combination for responding to the challenge. That article promoted the thesis that for urban conservation to become a mainstream activity, heritage professionals need to nurture relationships centrally within the broad discipline of geography – the core discipline of urban planning; and reciprocally, geographers need to recognise the vital role of urban heritage beyond a limited perception of its compass. The 2010 European Union Toledo Declaration acknowledged the importance of urban heritage, and defined the multiple dimensions of sustainability as economic, social, environmental, cultural and governance. Governance at the municipal level is the key to integrated urban planning policy and practice. This article explores current initiatives in the field and proposes directions for further research and implementation.

The heritage community has long faced difficulties with the theoretical as well as practical challenges of managing continuity on the scale of historic cities. Identifying individual components of the architectural heritage and selected areas for a variety of levels of conservation, from the benign to the interventionist, has largely proved to be the limit of attainment. In the generality of situations, where the survival of the components depends on their place within the whole, urban heritage is consequently at risk of suffering unnecessary losses. This is especially the case where the culturally sensitive historic cores of towns and cities are the primary focus of pressures for major change or redevelopment and counterbalancing policies are not in place to address those pressures proactively. Recent years have seen a number of reflections on urban heritage: notably, at the international level, by the United Nations Educational, Scientific and Cultural Organization (UNESCO) World Heritage Centre and the International Council on Monuments and Sites (ICOMOS). Deriving as they do from a vital but largely self-contained set of cultural heritage parameters and interests, their impact on positioning heritage at the core of urban planning and development processes has been limited. The essential human factor has not really been taken into account. With a focus on Europe, this paper looks beyond a paradigm founded on a limited perception of values to the objective of positioning the spectrum of urban heritage within the mainstream of urban planning policy and practice. This is a province dominated on a professional level by the broad discipline of geography, in which the urban geographer is the often-overlooked but essential ally for a constructive partnership. A second paper, in the following issue of this journal, takes the debate forward and addresses the governance of urban heritage.

Since the 1970s, the understanding of cultural heritage (CH) has expanded from a focus on monumental conservation to a systemic, socially constructed concept shaped by communities and dynamic values. While recognized as a resource for sustainable development, CH remains marginal in global policy agendas, notably in the UN’s 2030 Agenda. This paper explores how the Historic Urban Landscape (HUL) approach and broader heritage systems can function as enablers of sustainable urban development, moving beyond heritage-as-object to heritage-as-process. It synthesizes conceptual advances, policy frameworks, and empirical cases—such as Capitals of Culture programs, adaptive reuse initiatives, and circular economy models—to analyze how heritage systems contribute to environmental, social, and economic sustainability. Drawing on a value-based and people-centered framework, the paper identifies key principles, models, and success factors for integrating CH into urban planning. Case studies from Europe and Asia illustrate the potential of heritage to foster inclusive governance, community resilience, and innovation, while also exposing challenges such as institutional fragmentation, gentrification, and policy–practice gaps. The findings highlight the need for holistic, cross-sectoral, and participatory strategies to embed CH meaningfully in urban transformation processes, offering concrete insights for advancing heritage-led sustainable development through the lens of systems thinking.

Resilience, initially a concept rooted in psychology, has traversed disciplinary boundaries, finding application in fields such as urban planning and development since the 2010s. Despite its broad application, most definitions remain too abstract to allow their practical integration into urban planning and development contexts. Addressing this challenge, the European research projects SHELTER and ARCH offer a practicable integration of resilience with planning and development practices surrounding urban heritage. Following a systemic approach to resilience, both projects integrate perspectives from urban development, climate change adaptation, disaster risk management, and heritage management, supported with tools and guidance to anchor resilience in existing practices. This paper presents the results from both projects, including similarities and differences.

The purpose of this entry is to introduce the concept of Heritage-based Urban Development and explain its evolution and implications for historic urban landscapes. The term Historic Urban Landscape (HUL) refers to an integrated understanding of historic cities that goes beyond individual monuments or architectural ensembles to encompass the broader spatial, cultural, and functional relationships within the urban fabric. It reflects a shift toward viewing historic areas as dynamic systems with a role in sustainable development. Heritage-based urban development refers to development approaches that take urban heritage—typically within historic urban landscapes—as the starting point, valuing these landscapes in all their specificities, processes, and cultural meanings as resources to be embraced rather than obstacles to be overcome.
