Peasant’s Motivations for Managing Plant Diversity in Traditional Agroforestry Systems from the Tehuacán-Cuicatlán Valley, Mexico
摘要
This chapter summarized studies conducted in different communities of the Tehuacán-Cuicatlán Valley that explain the motivations that peasants have to manage the plant diversity of their agricultural plots or milpas, classified as traditional agroforestry systems. A qualitative analysis of different ethnobotanical, ecological, and management studies of these systems was carried out with information from semi-structured interviews, workshops, nonparticipant and participant observation, field diaries, and informal discussions. It was found that the main aspects influencing management decisions are the plant’s contributions to people, management feasibility, and sociocultural agreements. The maintenance of plant diversity is linked to the existence of formal and informal norms, as well as to the provision of multiple beneficial plant contributions (material, nonmaterial, and regulating) that satisfy some basic needs, especially sustenance, identity, and protection. Detrimental contributions motivate the removal of wild vegetation and are often of great importance to peasants, since they can affect agricultural production by competing with their crops, constitute the habitat of species considered harmful, pose potential risks, and hinder work. The perception of the abundant availability of elements of interest (such as water, soil, plants) and the efficiency of the practices to be carried out increase the viability of biodiversity management.
