Résumé
Ethnobotany, within the ethnoecology, is devoted to the understanding of human-plant relationships existing in traditional communities that are part of the biocultural diversity forged in the evolution of culture and nature. The present work approaches -from an ethnoecological approach- the knowledge of biocultural diversity in the Santo Domingo de Olmos Peasant Community. This community is located in one of the poorest areas of the country and due to its ecological characteristics, arid zone and with rainfall less than 10 mm of water per year, it is one of the most vulnerable to desertification processes and intense seasonal weather events such as El Niño. With the objective of documenting the human-plant interactions of the peasant populations settled in the study area, semistructured surveys and participatory methodologies were conducted to know the use and management of the plants, the results were as follows : Among the plants reported by the interlocutors 24 categories of use were registered, of which 64 plants were forage, 48 food, 32 medicinal, among others ; 8 management categories, including 5 in-situ, here the highest frequency was for tolerance interactions with 42.6% and 3 ex-situ where the transplant of individuals obtained 29.9% of the management, among others. Three large categories of agroforestry systems were identified, in which 13 types of agroforestry systems were recognized, highlighting scattered trees and shrubs in pastures, forests and agrosilvopastoral sites, community forest beekeeping and two new agroforestry systems for the area, among others. As for the dry forest cycles marked by the periodicity produced by El Niño-Southern Oscillation (ENSO), there were population movements, increase in economic activities, recovery of management forms associated with the re-emergence of the dry forest and times of scarcity lack of rain and drought
