Cities across Europe are increasingly exposed to extreme heat as climate change, urban densification and the progressive loss of ecosystem services converge. One of the most visible consequences of this convergence is the Urban Heat Island (UHI) phenomenon, which disproportionately affects dense and highly mineralised urban areas, with significant impacts on public health, social interaction and the liveability of public space. In 2022 alone, heat-related mortality in Europe exceeded 60,000 deaths, underscoring the urgency of effective and inclusive urban climate adaptation strategies.
In this context, Nature-Based Solutions (NbS) have gained growing attention for their capacity to mitigate urban heat while delivering co-benefits in terms of biodiversity, environmental quality and social well-being. By reintroducing vegetation, shade and water into urban environments, NbS offer an integrated approach to climate adaptation. Yet their implementation becomes significantly more complex in historic urban contexts, where cultural heritage protection regimes are often perceived as incompatible with environmental transformation.
This tension is particularly evident in European cities, whose historic centres combine high exposure to heat stress with strict and multilayered heritage protection frameworks. As a result, climate adaptation strategies frequently remain fragmented or are excluded altogether from some of the most climate-vulnerable urban spaces. Many historic streets and squares experience extreme surface temperatures, limited vegetation and declining public use, while regulatory rigidity discourages experimentation and cross-sectoral action.
At the core of this challenge lies a persistent assumption: that heritage protection and climate adaptation are mutually exclusive objectives. In practice, this assumption often leads to institutional inertia, with protected heritage sites treated as exceptions to climate policies rather than as priority areas for intervention. Such a framing overlooks the potential of Nature-Based Solutions to act as mediating tools between environmental performance, cultural value and social use.
When carefully designed and context-sensitive, NbS can contribute to microclimatic cooling in heritage contexts while respecting historical and architectural integrity. Reversible or low-impact interventions, selective greening strategies, shading solutions and the reallocation of public space away from heat-amplifying uses such as car parking can enhance thermal comfort without compromising conservation principles. Rather than altering the identity of historic places, these measures can help restore their habitability and civic function.
Crucially, the integration of Nature-Based Solutions in protected heritage sites depends less on technical feasibility than on governance capacity. Climate adaptation, heritage conservation and public space management are often addressed through separate policy silos, governed by different institutions, regulatory logics and professional cultures. In the absence of coordination mechanisms, shared objectives and collaborative decision-making processes, even well-designed NbS risk remaining isolated pilot projects or being blocked altogether.
Understanding heritage protection as a dynamic governance system rather than a static constraint is therefore essential. Aligning climate adaptation objectives with heritage management requires integrated policy frameworks, early institutional dialogue and regulatory approaches that allow controlled experimentation while safeguarding cultural value. In this sense, Nature-Based Solutions can act as catalysts for more coherent urban governance, helping cities reconcile the protection of historic identity with the urgent need to adapt to rising temperatures.
As climate models predict a growing frequency and intensity of extreme heat events across Europe, historic urban areas can no longer be treated as secondary within climate adaptation agendas. On the contrary, they represent critical spaces where environmental vulnerability, cultural significance and social life intersect most visibly. Addressing urban heat through Nature-Based Solutions in protected heritage contexts is therefore not only an environmental necessity, but also an opportunity to rethink how cities govern the relationship between climate action, cultural heritage and the collective right to liveable public spaces.
