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.
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.
Aujourd’hui encore, les forêts restent un enjeu vital. Ceci alors que le développement accéléré de beaucoup de régions provoque une pression croissante sur les écosystèmes forestiers. Parc Yasuni en Equateur, parc national des Virunga en RDC, ou plus largement forêts tropicales au Brésil ou en Indonésie, on peut multiplier les exemples de conflits socio-environnementaux où la question de l’utilisation et de la propriété des ressources forestières est l’objet de luttes féroces entre populations indigènes, ONG environnementales, multinationales et gouvernements, etc.
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.
The aim of this report is to provide a detailed review of documented social learning processes for climate changeand natural resource managementas described in peer-reviewed literature. Particular focus is on identifying (1) lessons and principles, (2) tools and approaches, (3) evaluation of social learning, as well as (4) concrete examples of impacts that social learning has contributed to.
Social learning in multi-actor innovation networks is increasingly considered an important precondition for addressing sustainability in regional development contexts. Social learning is seen as a means for enabling stakeholders to take advantage of the diversity in perspectives, interests and values for generating more sustainable practices and policies. Although more and more research is done on the meaning and manifestations of social learning, particularly in the context of natural resource management, little is known about the social dynamics in the process of social learning.
This study examines the influence of an extra-curricular educational program on children's knowledge and cultural valuation of wild food plants, which are an important component of their diets. This program aims to reinforce children's traditional knowledge and values around biological resources in Wayanad, India's Western Ghats, encouraging tribal and non-tribal children to learn from each other and from their own communities. Results show that the educational program has enhanced children's ability to identify selected wild food plants.
The agricultural innovation systems approach emphasizes the collective nature of innovation and stresses that innovation is a co-evolutionary process, resulting from alignment of technical, social, institutional and organizational dimensions. These insights are increasingly informing interventions that focus on setting up multi-stakeholder initiatives, such as innovation platforms and networks, as mechanisms for enhancing agricultural innovation, particularly in sub-Saharan Africa.
Many developing countries are experiencing a rapid expansion of supermarkets. New supermarket procurement systems could affect farming patterns and wider rural development. While previous studies have analyzed farm productivity and income effects, possible employment effects have received much less attention. Special supermarket requirements may entail intensified farm production and post-harvest handling, thus potentially increasing demand for hired labor. This could also have important gender implications, because female and male workers are often hired for distinct farm operations.
