In this assessment, three current management tools have been analysed, on their capabilities of preserving the Outstanding Universal Value (OUV) of Macao within the Historic Route, by relating the management tools to different attributes and changes in attributes. The attributes which have been analysed in relation to the management tools are derived from a previous research on attributes.
The results found by relating the attributes and changes of attributes between 2008 and 2013, with the management tools, contribute to a better understanding of the functioning of the current heritage management tools. The main result of this analysis has shown the Historic Route in Macao is not fully protected and managed as an ensemble, by either one of the current existing management tools. Therefore, changes in the Historic Route have or could have a negative impact on the OUV of Macao.
