REINOSO PEREZ, M; JOSEAU, M. J  and  VALDEZ, H. A. Alternatives for the agroecological management of woody shrub species in livestock agroecosystems in the northwest of Córdoba, Argentina. Agriscientia [online]. 2019, vol.36, n.1, pp.1-14. ISSN 1668-298X.

The objective of this research was to identify alternatives for the agroecological management of shrub species in livestock agroecosystems in the northwest of Córdoba, Argentina. Participatory techniques were used to determine the dominance of shrubs, the importance of the impact attributed to them, the feasibility of conventional control treatments and the prefeasibility of the alternatives for their agroecological management. The most dominant species were Vachellia caven, Celtis chichape, Senegalia gilliesii, Vachellia astringens, Geoffroea decorticans and Larrea divaricata. Management, profitability, colonization and accessibility were the most important negative impacts for 'productive' actors, while protection, diversity and feeding weres the most relevant positive impacts according to 'conservationists'. The feasibility of the control treatments ranged between 0.3 and 0.6, with higher values for rolling, harrowing and the combination of both. 83.3 % of the agro-ecological management alternatives obtained more than 50 % of the maximum possible value. The existence of multiples beneficial attributes in these species facilitates the implementation of management strategies and the productive use in agroforestal systems. The payment for environmental services, the pruning of the crown elevation, the rotational sequential grazing of cattle and goats, and the commercialization of the products derived from these plants, are the most promising alternatives.
