Precision agriculture (PA) is growing considerably in Brazil. However, there is a lack of information regarding to PA adoption and use in the country. This study sought to: (i) investigate the perception of growers and service dealership about PA technologies; (ii) identify constraints to PA adoption; (iii) obtain information that might be useful to motivate producers and agronomists to use PA technologies in the crop production systems.
Le développement de l'agriculture organique au Brésil prend des formes multiples. Au travers de leur expérience de l'AO, dans une communauté proche de trois métropoles, de petits maraîchers d'Ibiúna (São Paulo) créent des entités collectives et expérimentent de nouvelles pratiques sociales.
Le développement territorial durable requiert des innovations aussi bien techniques, que sociales et institutionnelles. Favoriser ces innovations est l'objectif des récentes démarches d'ingénierie territoriale qui adaptent les processus d'innovation développés en entreprise. Dans cet article, la pertinence de cette orientation est discutée en s'appuyant sur les enseignements d'une recherche-action, menée dans un territoire « fragilisé » : l' « Alto Sertão du Piauí et du Pernambouco », dans le Nordeste brésilien.
La consommation de produits certifiés n’est plus l’apanage des pays développés. Au Kenya, les premiers marchés biologiques sont apparus à Nairobi en 2006. Ils sont approvisionnés par des maraîchers, confrontés à une diversité de défis : construire une certification biologique crédible, garantir la fraîcheur des produits et composer avec l’hétérogénéité des attentes des consommateurs. À partir de données d’enquête et du cadre analytique des coûts de transaction, nous analysons l’organisation des marchés de 2006 à 2013.
Within the last four years, a number of high profile reports outlining new strategies for pulling African agriculture out of its current impasse have emerged. These include the Comprehensive African Agriculture Development Programme of NEPAD, and the InterAcademy Council Report commissioned by UN Secretary General Koffi Annan.
Numerous innovation platforms have been implemented to encourage the adoption of agricultural innovations and stakeholder interactions within a value chain. Yet little research has been undertaken on the design and implementation of innovation platforms focussing on issues other than market access and aiming to encourage agro-ecological intensification.
Innovation Platforms (IPs) have become a popular vehicle in agricultural research for development (AR4D). The IP promise is that integrating scientific and local knowledge results in innovations that can have impact at scale. Many studies have uncovered how IPs work in various countries, value chains and themes. The conclusion is clear: IPs generate enthusiasm and can bring together stakeholders to effectively address specific problems and achieve ‘local’ impact.
Although much has been written on how to implement and facilitate innovation platforms efficiently, few studies support ex-ante appraisal of when and for what purpose innovation platforms provide an appropriate mechanism for achieving development outcomes, and what kinds of human and financial resource investments and enabling environments are required. Without these insights, innovation platforms run the risk of being promoted as a panacea for all problems in the agricultural sector.
Rapid climatic and socio-economic changes challenge current agricultural R&D capacity. The necessary quantum leap in knowledge generation should build on the innovation capacity of farmers themselves. A novel citizen science methodology, triadic comparisons of technologies or tricot, was implemented in pilot studies in India, East Africa, and Central America. The methodology involves distributing a pool of agricultural technologies in different combinations of three to individual farmers who observe these technologies under farm conditions and compare their performance.
The globalisation of agrifood systems is a mega-trend with potentially profound nutritional implications. This paper describes various facets of this globalisation process and reviews studies on nutritional effects with a particular focus on developing countries. Results show that global trade and technological change in agriculture have substantially improved food security in recent decades, although intensified production systems have also contributed to environmental problems in some regions.
