In eastern Zambia, population growth has reduced per-capita land availability to such an extent that traditional bush fallows can no longer be practiced, and low soil fertility is a major constraint to crop production. Improved fallows (IF) based on leguminous trees are a low cash-input agroforestry practice to restore soil fertility. The objective of the study reported here was to assess the adoption of IF by farmers who tested the technology, including the extent to which the technology is practiced relative to its potential scale.
Cet article tente de répondre à la question suivante : au-delà des caractéristiques de l’exploitation agricole, quels sont les autres facteurs qui influencent les différents types d’innovation dans les filières stratégiques de l’agriculture algérienne ? En effet, la politique algérienne actuelle ambitionne de moderniser les filières stratégiques pour accroître la production, substituer la production nationale à l’importation et augmenter le volume des exportations.
Les informations géospatiales et leurs produits dérivés, conçus pour contribuer à la définition des politiques publiques agricoles, sont peu utilisés en Afrique. Les infrastructures, la formation et les compétences manquent ; les activités de recherche et développement sont dispersées et insuffisantes. Mais, surtout, les besoins restent mal formalisés et l’offre technologique, impulsée par les pays industrialisés, est peu adaptée aux caractéristiques des agricultures africaines.
Fall Armyworm (Spodoptera frugiperda), or FAW, is an insect native to tropical and subtropical regions of the Americas. In the absence of natural controls or good management, it can cause significant damage to crops. It prefers maize, although it can feed on more than 80 additional species of crops including rice, sorghum, millet, sugarcane, vegetable crops and cotton.
L’érosion hydrique est une préoccupation agronomique, économique et environnementale importante en milieu semi-aride méditerranéen. Le choix de la méthode pour l’estimer dépend des données disponibles et des conditions de la zone d’étude. Cet article vise à quantifier et spatialiser l’érosion hydrique en utilisant l’équation universelle des pertes en sol (Universal Soil Loss Equation [USLE]) dans ses versions modifiée (Modified − MUSLE) et révisée (Revised − RUSLE) et couplées à un Système d’information géographique (SIG) : MUSLE-SIG et RUSLE-SIG.
The concept of an innovation platform is increasingly used in interventions inspired by agricultural innovation systems thinking, as a way of bringing stakeholders from a sector together to enable transformative change. An essential role on such innovation platforms is thought to be that of the ‘innovation champion’, but this role has so far not been unravelled.
This book highlights the important links between agriculture and nutrition, both direct and indirect, both theoretical and practical. It explores these relationships through various frameworks, such as value chains, programmes and policies, as well as through diverse perspectives, such as gender. It assesses the impacts of various agricultural interventions and policies on nutrition and profiles the up-and-down journeys of countries such as Bangladesh, China, Ethiopia, India, and Malawi in integrating nutrition into agricultural policies and programmes.
There are divergent views on what capacity development might mean in relation to agricultural biotechnology. The core of this debate is whether this should involve the development of human capital and research infrastructure, or whether it should encompass a wider range of activities which also include developing the capacity to use knowledge productively. This paper uses the innovation systems concept to shed light on this discussion, arguing that it is innovation capacity rather than science and technology capacity that has to be developed.
This study examines the contributions of IFPRI over the last 10 years to policy development, training, and capacity-strengthening activities with Malawi, focused particularly on addressing the chronic food insecurity and malnutrition that has prevailed for the last 60 years.The paper is divided into five sections.
The findings of a Nigerian case study discussed in this paper indicate that the notion of wives of leisure is really not applicable to most women in Nigeria, as women have always worked. Even those in purdah engage in income generating activities within the confines of the compound. It is therefore wasteful to continue to by-pass or displace women in development. Selective mechanisation of difficult processes in agriculture could become a useful method of integrating women into, and enhancing their contributions to, development.
