Modelo Antropogógico de Extensión Agropecuaria: sensibilidad del retorno social de la inversión

Introduction / objective: the scarcity of resources for social investments requires strategies that increase the availability of information for decision-making. The Social Return on Investment (SROI) is a tool used for impact measurement and makes it possible to economically assess the effects of an intervention and identify the amount of change generated by each monetary unit invested. This index admits sensitivity analysis to recognize the aspects with the greatest influence on the impact of a project, so the objective of this work was to study the sensitivity of the SROI in the cocoa Territorial Laboratories of the University of Antioquia. Methodology: Through graphs, each of the changes was related to the SROI, identifying the highest levels of sensitivity in those whose values were located in quadrants 1 and 3 and whose trend line had an ascending performance. Results: The most sensitive variables were: the projection of income for 20 years, the increase in cocoa production, production above the break-even point, the satisfaction of basic and social needs, informal agreements for the succession of the production system, the initiation of soil conservation practices, the definition of activities to achieve the dream farm, and the implementation of the anthropogogical model of agricultural extension. Conclusions: Interrelationships were found between most of these variables and it was concluded that integral initiatives are the key to achieve greater social changes.
