Abstract

La adoption de la agricultura ecologica por parte de los agricultores implica un elevado grado de incertidumbre acera de la rentabilidad futura de la innovacion, lo cual hace que la implantacion de este metodo de cultivo y de explotacion agraria no sea immediata, sino un proceso de difusion dinamico. En este articulo se aborda el estudio de este fenomeno desde el punto de vista de los modelos de difusion de innocaciones aplicados a datos de la evolucion de la agricultura ecologica a lo largo de los ultimos 10 anos en Espana, Murcia ya Andalucia. La estimacion y el analisis de estos procesos permite conocer las caracteristias propias del proceso: en primer lugar, la difusion de la agricultura ecologica esta determinada fundamentalmente por el efecto imitacion. En segundo lugar, y con los datos disponibles, se deduce que el proceso alcanzo en nuestro pais su punto inflexion en el ano 1998. En conocimiento del modo en que tiene lugar este proceso de difusion puede ser de gran utilidad para el diseno e implementacion de politicas agrarias encaminadas a lograr la superacion de ciertas barreras que la agricultura ecologica aun encuentra en su umplantacion...Adoption of organic farming involves a high level of uncertainnes about future profitability of innovation, which causes a dynamic diffusion process instead of an immediate acceptance of this kind of crop and farm. The study of this fact is considered in this article from the Diffusion Models Innovation view point, and is applied to figures of organic agriculture evolution in Spain, Murcia and Andalucia during the last 10 years. Its estimation and analysis allows us to identify the most important characteristics of this process: first, the diffusion of organic agriculture is mainly determined by imitation effect. Second, and considering the available data, the process seems to reach its inflection point in 1998 in our country. The knowledge of the way this diffusion process takes place can be very useful for the planning and performance of agricultural policies addressed to overcome certain barriers that organic agriculture still has for its establishment.
