This research analyzed a sample of agricultural cultural landscapes recognized by United Nations agencies on the American continent, with the objective of study being the geographical delimitation established for each of the cultural properties. The results show the lack of “general considerations” that provide guidelines to carry out this activity, which consequently enables the protection of a territory and its management. It was identified that the perimeters of these cultural landscapes may have limits based on the following; geomorphological features, linear infrastructures, political–administrative limits, and if none of these limits are present then they are physically catalogued as vague or unclear. The establishment of general delimitation guidelines will allow the development of public policies for the organizing of such territory and a sustainable, dynamic, efficient, and resilient management for this type of living landscape.
