En la provincia de Guanacaste se observan dos estaciones bien marcadas a lo largo del año: la seca, que va de principios de noviembre a finales de mayo, y la lluviosa, que comprende los meses restantes. Sin embargo, en las últimas décadas, en el territorio nacional se han presentado importantes variaciones en las oscilaciones de precipitación y temperaturas que han impactado significativamente a esta provincia.
In this paper the developments in agricultural research and education in the Netherlands will be presented in a historic context and the recent evolutions in agriculture-based research and knowledge systems are evaluated. It is concluded that societal needs, scientific discoveries, and public and private funding are the driving forces behind change. However, most important for the quality and vigour of knowledge centres is the ability to adapt to change
En Europe, depuis trois décennies, la prise en compte des enjeux environnementaux dans les politiques agricoles se traduit, en partie, par la conception de Mesures agrienvironnementales (MAE), visant à promouvoir le changement de pratiques. En France, ces mesures ont été mobilisées dans différents modèles de contrats avec les agriculteurs, passant d’un paradigme basé sur la subvention de la multifonctionnalité d’une exploitation agricole à une compensation des surcoûts liés à l’adoption de nouvelles pratiques plus vertueuses au niveau des parcelles.
Les démarches de développement local sont assez standardisées : à partir d'un diagnostic territorial, on met en oeuvre un appui technique et financier aux organisations locales, pour la réalisation de projets dont elles assureront la gestion. Mais les organisations locales sont de nature variée, toutes n'ont pas forcément envie de gérer les équipements qu'elles demandent ; ceux-ci sont plus ou moins complexes à gérer et certains relèvent des prérogatives communales. Enfin, le diagnostic initial dépend de la logique d'ensemble de l'action.
The aim of the present article is to propose a new approach to improve interactions between stakeholders, using traceability and contractualization. Faced with a crisis generated by volatility, collective action, incorporating all stakeholders, including consumers, is needed: but what exactly must be done? The article first describes the SDSC approach which combines three main concepts: Extended Demand, Extended Supply and Demand-Supply Chain (DSC), and then goes on to detail how a collaborativemodeling tool needs to be built up.
In this paper, the authors review the conditions that have been undermining sustainable food and nutrition security in the Caribbean, focusing on issues of history, economy, and innovation. Building on this discussion, we then argue for a different approach to agricultural development in the Small Island Developing States of the CARICOM that draws primarily on socioecological resilience and agricultural innovation systems frameworks.
Innovation platforms are widely used in agricultural research to connect different stakeholders to achieve common goals. This brief deals with the gender dimension in innovation platform and is part of the series of ‘practice briefs’ intended to help guide agricultural research practitioners who seek to support and implement innovation platforms.
The process of adopting innovation, especially with regard to precision farming (PF), is inherently complex and social, and influenced by producers, change agents, social norms and organizational pressure. An empirical analysis was conducted among Italian farmers to measure the drivers and clarify “bottlenecks” in the adoption of agricultural innovation. The purpose of this study was to analyze the socio-structural and complexity factors that affect the probability to adopt innovations and the determinants that drive an individual’s decisions.
This article presents lessons from the rich adoption literature for the nascent research on adaptation. Individuals' adoption choices are affected by profit and risk considerations and by credit and biophysical constraints. New technologies spread gradually, reflecting heterogeneity among potential adopters, processes of learning and technological improvement, and policies and institutions. Adaptation is the response of economic agents and societies to major shocks. We distinguish between reactive and proactive adaptation.
Social learning processes can be the basis of a method of agricultural innovation that involves expert and empirical knowledge. In this sense, the objective of this study was to determine the effectiveness and sustainability of an innovation process, understood as social learning, in a group of small farmers in the southern highlands of Peru. Innovative proposals and its permanence three years after the process finished were evaluated. It was observed that innovation processes generated are maintained over time; however, new innovations are not subsequently generated.
