Abstract
El presente trabajo se basa en un seguimiento a un grupo de explotaciones agrarias de la zona montanosa de Las Alpujarras, situada al sureste de Espana, durante dos decadas consecutivas: 1981-1991 y 1991-2001. Tras comentar brevemente los cambios acaecidos, en la primera decada, expuestos ya en trabajos anteriores, se analiza la permanencia o no de la actividad comercial d las explotaciones en el 2001, tratando de identificar los factores que determinan dicha permanencia. para ello, se ha ajustado un modelo Probit binomial analizado la relacion entre la permanencia de las explotaciones agrarias en el 2001 y su nivel de marginalidad, la pratica de la agricultura a tiempo parcial, la dimension de la explotacion y la centa de los productos a traves de cooperativas. El nivel de marginalidad se mide mediante un indice de remuneracion de la mano de obra total empleada en la actividad agraria. Finalmente a modo de conclusiones, se ofrecen algunos comentarios relativos al impacto de los programas europeos de desarrollo rural iniciados en la zona en 1991, sobre las explotaciones agrarias...The present study is based on the folloq-up of a group of farms in the mountain areas of the Alpujarras, located in southeastern Spain, over two consecutive decades: 1981-1991 and 1991-2001. After a brief commentary on the changes that took place during the first decades, and which were presented in earlier studies, the permanence or disappearance of the farms as commercial units for the year 2001 is analysed, and factors determining this permanence are identified, To this end, a Probit binomial model has been adjusted to analyse the relationship between the permanence of the farms in 2001 and their level of marginality, part-time farming, the relative sizes of the farmlands, and the sale of their products through co-ops. The marginality level has been measured by the rate of remuneration from the total hand labour used for the agrarian activity. Fianlly, conclusions are drawn, in which some comments on the impact on these farms of the EU rural development programmes, which began in the area in 1991, are included.
