The world is facing global challenges that are dramatically changing the social and physical environments, resulting in cultural confrontation. Rapid urban growth, and gentrification increase urban pressure while jeopardizing social cohesion, multicultural values and local economies. Moreover, environmental factors associated with climate change challenge the way cities respond
and adapt, as their assets have to be re-designed to meet the current and future generation needs.

One response to these challenges is adaptive reuse, the transformation of the function of an underused structure into a new use. This process turns the cities’ elements in decline into development catalysers. The adaptation to these changes is often a source of conflict, as urban policies lack citizen engagement in the redefinition of public space, resulting in more disagreement. This is particularly acute when addressing contested communities, as their continuous evolution directly influence the adaptation of cultural heritage.

Considering these aspects, this research question is responded: ‘How can socio-spatial conflicts that result from contested identities be mitigated through the adaptive reuse of urban heritage?’.

The relations between Adaptive Reuse, Urban Heritage and Contested Identities are studied, resulting in the research’s objective: to develop an integrative methodology to evaluate urban heritage adaptive reuse alternatives in contested urban contexts, using the case of Acre (Israel).

This final outcome is proposed as a tool for decision-makers and urban planners that provides information-based results to be applied in urban design practice, aiming to translate the theory into practice, and to bridge the gap between global goals and local issues.

The world is undergoing dramatic change in its social and physical environments, resulting in cultural confrontation and conflict. Rapid urban growth, displacement, and gentrification increase urban pressure while jeopardising social cohesion, multicultural values, and local economies. In addition, environmental factors associated with climate change challenge how our cities respond and adapt, prompting the need for urban centre regeneration to confront the urban century challenges (Sassen, 2011). However, adaptation to these changes is also a source of conflict, as urban policies lack citizen engagement in the redefinition of public space, resulting in more disagreement and inefficient use of resources. One way to respond to this ongoing crisis is adaptive reuse, repurposing an underused system for a new use. This process can enhance positive environmental impacts, encourage social and participatory processes, and promote economic dynamism through culture. However, the success of such an intervention will depend on the underlying approach. The paper aims to explore how Jem Bendell’s ambitious four-pronged Deep Adaptation strategy (Bendell, 2018) combined with the cultural resilience approach can result in adaptive reuse processes that act as development catalysers and peace-building mechanisms. .

Purpose
Cities are facing challenges that dramatically affect their social and physical landscapes, leading to the increase of urban segregation and polarization. One response to these challenges is adaptive reuse, yet, in heterogeneous communities, these adaptations are often a source of conflict, because local actions often lack an integrative approach, leading to further exclusion. In this paper the authors explore the potential of adaptive reuse of urban heritage as a planning tool to support inclusiveness and heterogeneity.

Design/methodology/approach
The city of Acre is used as a case study, where different scenarios for urban heritage are proposed and tested among stakeholders through interviews. These aim to explore how adaptive reuse processes can lead to the inclusion or exclusion of certain groups and how design interventions in historic urban landscapes challenge the way the current disconnected historic and urban layers interact.

Findings
The paper presents the commonalities and differences between the interviewees' perceptions on Acre's functioning, their idea of inclusiveness and other aspects related to urban design. Moreover, it highlights the existing conflicts of interest, value prioritization and the adequacy of the proposed scenarios, serving as a way to verify the accuracy of the scenario building process.

Originality/value
Testing an urban design tool related to adaptive reuse of urban heritage in a real and extreme case, based on the guidelines of the Historic Urban Landscape Recommendation; and critically analysing the sources of conflict and value systems to address inclusion in heterogenous settings.
