El objetivo de este trabajo es analizar de manera comparativa los condicionantes (o limitantes) de la adopción de Tecnologías Críticas Comunes (TCC) en maíz y soja en tres provincias del país: La Pampa, San Luis y Chaco con la finalidad de delinear políticas de investigación y extensión prioritarias. Los cultivos fueron seleccionados de acuerdo a las prioridades fijadas por los Centros Regionales de INTA debido a su importancia en cada provincia.
The paper presents an efficient approach for the modelling of wire robots kinematic and dynamics considering the effects of structural elasticity. Using the simulation and animation system several potential applications in agriculture have been simulated and analysed. The paper discusses possible robot configurations, system dynamic constraints and limits, as well as reachable performance for typical large-span wire robot applications in agriculture.
This paper explores the potential of Actor Network Theory (ANT) in understanding how the process of interaction and translation between human and non-human actors contribute to the development, adoption and diffusion of science-based innovations linked to the transition to organic farming. The study relies on two case studies, the French Camargue case covering a range of technical and social innovations, and the case from Bulgaria focusing on the development of a technical and product innovation, i.e. a veterinary product for organic beekeeping.
The objective of this research was to explore the use of data information of a low-cost IMU to provide an attitude angle with acceptable accuracy for agricultural robot navigation. This work was an attempt to create attitude angle estimation system via sensor fusion method based on gyroscope and accelerometer in this low-cost IMU. The used algorithm processed and integrated the data from triple gyroscope and tri-axis accelerometer using a low-pass filter and Kalman filter. Under this algorithm, experiment data showed that the estimation precision was improved effectively.
La conférence sur « Agriculture écologique : atténuer le changement climatique, assurer la sécurité alimentaire et l’autonomie pour les sources de revenus ruraux en Afrique » s’est tenue à Addis – Abéba (Ethiopie) du 26 au 28 novembre 2008.
This paper provides background information and introduce the topics of the conference "Innovation systems for food security and nutrition: understanding the capacities needed". Organized by the Tropical Agriculture Platform, the conference aimes at bringing together the issues of capacity development, agricultural innovation, and food security and nutrition with the objective of developing recommendations for policy-making.
This paper examines innovations for bridging gender gaps in agricultural value chains in Africa. It focuses on innovative platforms for addressing gender gaps, considering women contribute up to 40 percent of labor in agricultural production. Women remain at the bottom of value chains and face gender-specific constraints attributable to gender and social norms, discriminatory beliefs and practices, gender-blind designs and delivery of technologies and innovations which impede women s participation in value chains.
More than 25 years after the first implementation of Farmer Field Schools (FFS), there is a rich corpus of evidence that participation in FFS improves farmers’ knowledge, skills, and competencies. On the other hand, several studies converge to show that FFS, by strengthening group action, have the potential to build-up social capital among participants and, thereafter, within local communities.
Economic development and the successful transformation ofagriculture have been at the core of impressive change in countriessuch as China, India, Indonesia, Brazil, Mexico, and Argentina. This transformation has relied on substantial and effective investment inagriculture, and, in particular, building capacity in all aspects of agricultural change – from technology development and transfer through infrastructural development and the processing of agricultural commodities into consumer products.
This paper uses the Mexican Sustainable Modernisation of Traditional Agriculture (Ma-sAgro) programme as a case study to analyse the challenges to operationalizing agricultural innovation systems. The authors outline the relationship between Mexico ́s extension approaches and global trends in technological change. They then analyse how MasAgro ́s innovatio nnetworks are operationalized. Thirdly, is identified ways to efficiently target in innovation networks, using a case-study from the state of Chiapas. Finally, the paper draw lessons from MasAgro ́s innovation systems.
