protecting these conditions. The goal of the LCA is to manage visitor impacts, rather than the number of visitors. In order to determine the LCA, a participatory, comprehensive, collaborative and committed, non-simulated process is necessary to define management objectives; Identify what will be measured socially and environmentally and establish measurable standards to maintain those conditions. That is, it is necessary to have a very complete and clear picture of the entire system and its operation, from social to environmental aspects, to determine the future social and environmental conditions that will be desirable. Not as subjective desires and good intentions, but as elements documented in depth and analyzed from the panoramic view of territory or landscape, not from the scale of species or specific site. Appropriate indicators must be established in order to assess the desirable social and environmental conditions, established in the previous step. For the design of indicators, it is key to be able to select the appropriate counselors that fit the particular conditions of a site, activity or function, if you want to have an effective evaluation tool. It is not enough to establish what is to be measured, it is necessary to establish the minimum acceptable values in order to be able to make management decisions in time to reduce the potential for unacceptable change. These measures are used to inform the establishment of monitoring programs and management activities to ensure the maintenance of site conditions. The process must necessarily be collaborative because in the end consensus and commitments must be achieved by all actors. The key is that the actors involved represent the majority of the groups in the system that make direct or indirect use of it, that will benefit directly or indirectly, or that will be affected by the decisions taken. In the end there must be a consensus on the amount of change that is acceptable to all parties and not just one sector of society. When reviewing the Acceptable Change Limit methodology, proposed by Stankey, et al (1985) it consists of 9 steps with their purposes, processes and products. Together they are a continuous process of obtaining information for planning, generation of indicators and strategies for follow-up, monitoring and permanent feedback.
