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.
The Colombian Ministry of Agriculture Colombia, an international research center and a national farmers’ organization developed a data-driven agricultural program that: (i) compiles information from multiple sources; (ii) interprets that data; and (iii) presents the knowledge to farmers through the local advisory services. Data was collected from multiple sources, including small-scale farmers. Machine learning algorithms combined with expert opinion defined how variation in weather, soils and management practices interact and affect maize yield of small-scale farmers.
The Farmer Field School (FFS) approach has been very successful and witnessed a strong expansion in many areas beyond crop production. Notwithstanding this success, the adoption of FFS in national extension often remains problematic and FFS activities have often been implemented in the margin of national institutions with strong reliance on donor funding. The creation of an enabling environment for institutional support is essential for expanding the effort, improving quality, and strengthening impact and continuity of the FFSs.
The private sector dominates biotechnology research in industrialized countries, but there are major market failures in developing countries in accessing the new tools and technologies. The public sector, national and international, will have to play a major role in filling this gap. This paper provides an overview of options that countries of different sizes and capacities can employ to gain access to the research tools and technologies that they need to address issues of relevance to poor producers and consumers.
This paper outlines key areas of intervention that are identified as the core of FAO's strategy on strengthening Agricultural Innovation Systems (AIS) across multiple areas of work (e.g. research and extension, agroecology, biotechnology, green jobs, resourcing etc.) for achieving sustainable rural development.
Dans le besoin urgent de lutter contre le changement climatique, une priorité essentielle est de renforcer la capacité de ces groupes et communautés les plus vulnérables, et déjà fortement affectés, à améliorer leur capacité à adapter leurs systèmes de subsistance.
Qu’en est-il des « activités non agricoles » ? Peuvent-elles être pensées au-delà d’une perspective de survie ? De la transformation des récoltes à la commercialisation d’artisanat culturel, en passant par le transport routier, la location de téléphone portable ou le conseil en technologies de l’information, les activités non agricoles occupent un éventail très large. Leur utilité est de plus en plus reconnue.
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.
Small-scale farmers' experimental innovations have not generally been considered for on-farm research trials as those in the traditional sector have been perceived as recipients, rather than originators, of technical knowledge and sustainable and viable practices. Yet there is abundant evidence throughout the tropics that small-scale farmers are adaptive and experimental problem solvers, and experts at devising innovative survival strategies. While literature on the topic is rich with accounts from Africa, Asia and Latin America, there is a general dearth of examples from the Caribbean.
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.
