Multifunctional agrifood systems with noteworthy roots in a territory are the result of a historical yet dynamic specialization. They are present in the place's knowledge, social connections, collective action, the organization of institutions, innovation and capital. These systems are seen in the landscape, which becomes a resource as well as cultural and environmental heritage. In this regard, it is necessary to study the significance of the many aspects of heritage and landscape in agrifood systems to suitably manage and appreciate them as a territorial resource. This study develops and applies a quantitative method with various criteria to enable the landscape values of multifunctional, territorialized agrifood systems (MTAS in Spanish) to be evaluated, paying attention to essential matters such as the process of heritage recognition and the quality of their landscapes. To do so, a method designed by the authors for evaluating landscapes has been adapted to the peculiarities that define such systems, made up of criteria such as representativeness, authenticity, ecological integrity, vulnerability, accessibility and historical, social and symbolic values. The method has been applied to an exemplary Mediterranean landscape, the agricultural gardens of Valencia, which combine features of MTAS in metropolitan and coastal flatland contexts.
