Limits of Acceptable Change (LAC) for Tourism Development in the Historic Centre of Porto (Portugal)

Abstract

The present study proposes to analyse the impacts of tourism in the historical area of the city of Porto in Portugal, according to the perception of the resident population, in order to define the limits of acceptable change (LAC) for tourism development in this area. Literature suggests that the impacts of tourism are felt more intensely by communities living in tourism destinations, and, because of this, they must be involved to play an active role in the development of local tourism policies. For that reason, the analysis of tourism impacts considering local perceptions is an essential part of adequate tourism planning and management process. The LAC method can be applied in the management of these tourism areas with the need to adapt and consider the changes caused by tourism, helping in the development of strategic plans to support sustainable development. It must be characterised by the active involvement of the community throughout the process, while decisions should be based on results that are acceptable to a variety of stakeholders. Based on the concepts mentioned above and the proposed objectives, the research methodology follows a qualitative approach. The data collection process was based on three focus groups with the participation of several stakeholders involved and/or affected by the development of tourism in the area. Those focus groups underpinned the LAC method and participatory planning, which contributed to the definition of the limits of acceptable change considering tourism development in the historic centre of Porto.
