The objective of this study is to evaluate the ability of soil physical characteristics (i.e., texture and moisture conditions) to better understand the breeding conditions of desert locust (DL). Though soil moisture and texture are well-known and necessary environmental conditions for DL breeding, in this study, we highlight the ability of model-derived soil moisture estimates to contribute towards broader desert locust monitoring activities.
Contract farming has gained in importance in many developing countries. Previous studies analysed effects of contracts on smallholder farmers’ welfare, yet mostlywithout considering that different types of contractual relationships exist. Here, we examine associations between contract farming and farm household income in the oilpalm sector of Ghana, explicitly differentiating between two types of contracts,namely simple marketing contracts and more comprehensive resource-providing contracts.
Individuals from a diverse range of backgrounds are increasingly engaging in research and development in the field of artificial intelligence (AI). The main activities, although still nascent, are coalescing around three core activities: innovation, policy, and capacity building. Within agriculture, which is the focus of this paper, AI is working with converging technologies, particularly data optimization, to add value along the entire agricultural value chain, including procurement, farm automation, and market access.
Le conseil agricole occupe une place prépondérante dans l’appui aux processus d’innovation, particulièrement dans les pays du Sud. Or, l’accompagnement de l’innovation nécessite une diversité de formes d’appuis, appelés services support à l’innovation (SSI). À partir d’une analyse exploratoire à Madagascar, cet article questionne la place du conseil agricole vis-à-vis de la diversité des organisations et des activités d’accompagnement de l’innovation.
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.
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.
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.
