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.
With a large proportion of sub-Saharan African countries’ GDP still heavily reliant on agriculture, global trends in agri-food business are having an increasing impact on African countries. South Africa, a leader in agribusiness on the continent, has a well-established agri-food sector that is facing increasing pressure from various social and environmental sources. This paper uses interview data with corporate executives from South African food businesses to explore how they are adapting to the dual pressures of environmental change and globalisation.
The objective of this paper is to explore the extent to which systems approaches to innovation are reflected in the crop protection literature and how such approaches are used. A systematic literature review is conducted to study the relation between crop protection and systems approaches to innovation in 107 publications. The analysis of the crop protection literature demonstrates that only a small fraction is systems-oriented as compared to the bulk of publications with a technology-oriented approach.
Dans le contexte de changements environnementaux et socio-économiques, l’agriculture en Afrique sub-saharienne devra assurer la sécurité alimentaire des populations, tout en limitant son empreinte écologique. Les contraintes biophysiques et sociales des systèmes de production agricole sont complexes. Les pratiques agricoles innovantes seront basées sur une intensification des processus écologiques qui déterminent le fonctionnement du système sol–plante, des parcelles cultivées ou des agroécosystèmes.
Agricultural biotechnology and, specifically, the development of genetically modified (GM) crops have been controversial for several reasons, including concerns that the technology poses potential negative environmental or health effects, that the technology would lead to the (further) corporatization of agriculture, and that it is simply unethical to manipulate life in the laboratory. GM crops have been part of the agricultural landscape for more than 15 years and have now been adopted on more than 170 million hectares (ha) in both developed countries (48%) and developing countries (52%).
The food production and processing value chain is under pressure from all sides—increasing demand driven by a growing and more affluent population; dwindling resources caused by urbanization, land erosion, pollution and competing agriculture such as biofuels; and increasing constraints on production methods driven by consumers and regulators demanding higher quality, reduced chemical use, and most of all environmentally beneficial practices ‘from farm to fork’.
Boll guard I & II were introduced in 2002 and 2006 by Mahyco Monsanto with Genetic Engineering Appraisal Committee, Govt. of India. Indian cotton farmers adopted Bt hybrid cotton between 2002-2013 reaching 92% of the cotton area and 95% of the production, replacing conventional hybrids/ varieties of all the species in both rainfed and irrigated conditions. Bt hybrid cotton was presumed to produce record highest average productivities in India and other major cotton growing countries also in 2007 and 2012 with a decline after 2008 due to excess rains. Farmers invested Rs.
Este estudio analizó la evolución de una red de innovación entre productores de hule natural durante tres periodos de observación (dos olas o tres años), y evaluó cómo los productores reaccionan a diferentes innovaciones en un momento dado. Las prácticas de innovación fueron agrupadas en tres actividades: control de plagas y enfermedades, establecimiento y manejo de plantaciones, y manejo de cosecha y poscosecha.
La extensión rural es un proceso de trabajo y acompañamiento con el productor orientado al desarrollo sostenible de sus capacidades. En México, se han adaptado una serie de modelos de extensión que van desde el norteamericano, implementado a principios de la década de 1980, hasta el modelo de hub o nodo de innovación (plataforma - módulo demostrativo - área de extensión), aplicado desde el 2010 en el marco del Programa MasAgro. El objetivo de este documento es analizar los diversos procesos de extensión en México.
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.
