Transgenic maize was approved in Brazil in 2008/2009. In 2012, it occupied 73% of the country maize growing area. This high adoption rate confirms studies indicating that technology use has been the major driving force in Brazilian agriculture. Maize seed market in the world has been a concentrated sector. Although, when this sector is associated with transgenesis, this concentration increases sharply. In one side, there is the idea that companies can benefit from gains of scale and complementarities to maximize their efficiency in research and development (R&D).
Ce guide est le premier d’une série consacrée à l’application pratique,sur des cultures de petits producteurs et des systèmes de production agricole spécifiques, du modèle «Produire plus avec moins» de la FAO. Sa publication intervient alors que la production du manioc s’intensifie à l'échelle mondiale, avec une transition des producteurs utilisant les systèmes traditionnels de culture vers la monoculture, vers des génotypes à rendement élevé et vers un recours accru aux produits agrochimiques.
Descendu des hauts plateaux andins pour arriver dans nos assiettes, le quinoa est entré dans le jeu économique où l’offre, la demande et le prix forment un cadre triangulaire aux paradoxes multiples.
On ne peut pas s’intéresser au monde rural sans parler des organisations paysannes (OP). Acteurs clés du développement rural, les OP sont des maillons importants entre le paysan et SOS Faim. Dans ce numéro, nous nous intéressons aux OP africaines car en Amérique latine, les regroupements de producteurs se manifestent davantage sous la forme de coopératives.
En síntesis, el presente documento tiene un carácter marcadamente exploratorio. Por lo tanto, el objetivo es modesto pues no se pretende medir o evaluar los efectos, sino identificarlos y describirlos en la medida que los actores del proceso los signifiquen como tales. Esto permitirá, a futuro, estudios más profundos sobre la base de una mejor compresión de las lógicas intrínsecas de los procesos de innovación. El documento está organizado en cuatro apartados. El primero resume las aproximaciones conceptuales relevantes sobre el tema.
The Guyana School of Agriculture (GSA) was established in the year 1963 by former President Dr. Cheddi Jagan. It became a state corporation in 1964 offering the Diploma in Agriculture and the Certificate in Agriculture Programmes, and graduated the first batch of 15 students in 1966. Agricultural diversification has become an important mechanism for economic growth by providing opportunities that facilitate technological advancement and demand driven government policy.
The availability of an efficient PRRS virus monitoring information system for a large scale project remains a major issue. The purpose of this paper is to present the system developed by CDPQ (Quebec Swine Development Center) to support Quebec’s province-wide PRRS monitoring effort (3000 sites).
CABI’s Plantwise programme runs local plant clinics in 24 countries across Africa, Asia and Latin America where trained ‘plant doctors’ provide on-the-spot diagnosis and advice for farmers who bring samples to the clinics. A database that records each consultation and shares knowledge across clinics and countries continually builds the ability of the programme to respond to farmers’ needs. The programme embodies key principles of an innovation systems approach.
Rural extension is a process of work and accompaniment with the producer aimed to sustainable development of their skills. In Mexico, a series of extension models have been adapted, that goes from the US, implemented in the early 1980’s, to the hub model or innovation node (platform - demonstration module - extension area) applied since 2010 under the MasAgro Program. The aim of this paper is to analyze the various processes of extension in Mexico.
