Agroforestry (AF) systems have been the focus of numerous research and development projects in southern Africa, yet their adoption rate generally remains low. Employing on-farm, participatory research techniques in southern Malawi, was compared the suitability of three AF-based systems that relay crop the dominant staple, maize (Zea mays), with the perennial legumes Sesbania sesban, Tephrosia vogelii, and Cajanus cajan (pigeonpea).
This book is the re-titled third edition of the widely used Agricultural Extension (van den Ban & Hawkins, 1988, 1996). Building on the previous editions,Communication for Rural Innovation maintains and adapts the insights and conceptual models of value today, while reflecting many new ideas, angles and modes of thinking concerning how agricultural extension is taught and carried through today.
African farming systems are highly heterogeneous: between agroecological and socioeconomic environments, in the wide variability in farmers’ resource endowments and in farm management. This means that single solutions (or ‘silver bullets’) for improving farm productivity do not exist. Yet to date few approaches to understand constraints and explore options for change have tackled the bewildering complexity of African farming systems. In this paper we describe the Nutrient Use in Animal and Cropping systems – Efficiencies and Scales (NUANCES) framework.
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.
La sécurité alimentaire en Algérie semble plus que menacée par un niveau de croissance démographique incontrôlé, par la dégradation des conditions physiques du secteur de l’agriculture, par la baisse des ressources hydriques et par le retard de développement technique de l’activité. À partir d’une revue bibliographique sur la situation actuelle du secteur agricole, le texte définit ses niveaux de développement et les défis de l’avenir auxquels ce secteur sera confronté.
Des changements dans les agendas des politiques publiques des Comités Nationaux de l’Agriculture Familiale des Philippines, du Honduras, du Burkina Faso et du Sénégal seront soutenus techniquement et économiquement. La création d’un nouveau Comité au Tchad sera également appuyée.
De octubre del 2014 a noviembre del 2016, el Instituto Interamericano de Cooperación para la Agricultura (IICA) y la Coordinadora Latinoamericana y del Caribe de Pequeños Productores y Trabajadores de Comercio Justo (CLAC) ejecutaron el proyecto “Fortalecimiento de capacidades agroempresariales y asociativas de organizaciones de pequeños productores para su vinculación a los mercados locales utilizando el modelo de agronegocios de comercio justo”, con recursos del Fondo de Cooperación Técnica del IICA (FonCT)1 y la CLAC2 .
This paper describes the research path followed by a team of researchers who had investigated the nitrate problem in a case study area, and who became aware of the low impact of their data on the policy debate and on the practices that – as the research team saw it – had given rise to the problem in the first place. They embarked on a series of interactions first with participatory action researchers from the SLIM project (see Fig.
On-farm agricultural innovation through incorporation of new technologies and practices requires access to resources such as knowledge, financial resources, training, and even emotional support, all of which require the support of different actors such as peers, advisors, and researchers. The literature has explored the support networks that farmers use and the overall importance ranking of different support actors, but it has not looked in detail at how these networks may differ for different farmers.
The Papa Andina network employs collective action in two novel approaches for fostering market chain innovation. The participatory market chain approach (PMCA) and stakeholder platforms engage small potato producers together with market agents and agricultural service providers in group activities to identify common interests, share market knowledge and develop new business opportunities.
