L’agriculture française fait l’objet de critiques du fait des pressions qu’elle exerce sur les ressources naturelles, des transformations qu’elle opère sur les paysages et de la qualité parfois contestée de ses productions. Face aux attentes sociales et aux pressions réglementaires, des agriculteurs ont choisi de s’organiser en réseau pour proposer des pratiques agricoles alternatives. Une véritable dynamique est en œuvre chez ces agriculteurs minoritaires qui cherchent à diffuser leurs expériences en créant de nouveaux liens au sein de la population agricole.
El objetivo de este trabajo es analizar el Cluster de Frutas Dulces de Lleida-Huesca y los elementos que intervienen en las interrelaciones entre los grupos de interés (stakeholders). Se realizaron entrevistas a expertos y encuestas a procesadoras, cuya información ha permitido caracterizar el cluster y las empresas, así como los elementos que determinan la Calidad de la Relación entre dichas empresas y grupos.
La agricultura intensiva mediterránea ha desarrollado en el último tercio del siglo XX importantes concentraciones territoriales de la actividad productiva de frutas y hortalizas en áreas determinadas del litoral español. Las ubicaciones de estos sistemas productivos de origen agrícola responden a una mezcla de condiciones naturales, históricas, económicas e institucionales.En este artículo se analizan los componentes de este cluster agroindustrial y su comportamiento evolutivo, para finalmente concluir si esta aglomeración productiva reúne los requisitos de un distrito industrial
To give more attention to the normative character of sustainable development, the Dutch Ministry of Agriculture, Nature, and Food Quality requested for a participatory approach to evaluate Dutch agriculture, which was characterized by stakeholder workshops, dialogue, and learning. This article describes and reflects on this approach, using the Fourth Generation Evaluation framework developed by Guba and Lincoln (Fourth generation evaluation, 1989).
Este trabajo se centra en el análisis de los impactos del sistema regional de innovación en el País Vasco, y especialmente en su capacidad para impulsar la transformación estruc-tural de la economía vasca y potenciar su competitividad en el contexto de la creciente globalización y ampliación de la UE.
Familiar mixed dairy sheep farm is the most widespread system in the Mediterranean basin, in Latin America and in developing countries (85%). There is a strong lack of technological adoption in packages of feeding and land use in small-scale farms. To increase competitiveness, it would be of great interest to deepen the knowledge of how innovation was selected, adopted, and spread. The objective of this research was to select strategic feeding and land use technologies in familiar mixed dairy sheep systems and later assess dairy sheep farms in Spain.
The potential beneficial and harmful social impacts generated by the introduction of novel technologies, in general, and those concerning nutrient recovery and the improvement of nutrient efficiency in agriculture, in particular, have received little attention, as shown in the literature. This study investigated the current social impacts of agricultural practices in Belgium, Germany and Spain, and the potential social impacts of novel technologies introduced in agriculture to reduce nutrient losses.
The digital transformation in agriculture introduces new challenges in terms of data, knowledge and technology adoption due to critical interoperability issues, and also challenges regarding the identification of the most suitable data sources to be exploited and the information models that must be used.
The determination of bunch features that are relevant for bunch weight estimation is an important step in automatic vineyard yield estimation using image analysis. The conversion of 2D image features into mass can be highly dependent on grapevine cultivar, as the bunch morphology varies greatly. This paper aims to explore the relationships between bunch weight and bunch features obtained from image analysis considering a multicultivar approach.
