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.
This paper examines reconfigurations of household economies and agrobiodiversity through the experiences and responses of rural households to local manifestations of globalisation and environmental change in the Central Valley of Tarija, Bolivia, from the 1950s to the present. Research participant narratives from seven study communities document a widely experienced regional shift from rain-fed agriculture and pastured livestock production for household consumption to market-oriented production of regionally-specialised commodities.
This paper addresses how co-producing knowledge can assist local farmers in reshaping their territories into sustainable farming systems. We describe the emergence and consolidation of an agroforestry system in an Eastern Amazon forest frontier, unpacking the co-production of a new farming system over recent decades. Instead of assuming pre-defined categories (e.g., traditional/technical, local/external), the analysis focuses on interactions among knowledge holders and how multiple knowledge sources are intercalated.
The future of inclusive forestry in Nepal depends on forestry professionals who can recognise patriarchal roots of gender injustice as they operate in the ideologies and apparatus of forest governance, and who can resist those injustices through their work. This paper uses the notion of knowledge practices to explore the recognition of injustice amongst Nepal’s community forestry professionals, and the relationship between recognition and resistance, highlighting the inherently political nature of all knowledge practices.
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.
Dans le contexte des masses de données textuelles liées à l’agriculture aujourd’hui disponibles, leur indexation devient un enjeu crucial pour les organismes de recherche. Une manière d’indexer au mieux les documents consiste à en extraire la terminologie. Cet article explore l’utilisation et la combinaison de méthodologies de fouille de textes afin de mettre en exergue, puis de publier dans des systèmes d’open data, les termes les plus adaptés issus de documents.
This article provides an overview of some of the recent research in agriculture involving remote sensing and GIS. Attention focuses on application of remote sensing and GIS specially in agriculture including geography, land surveying, most Earth Science disciplines, parent child relationship, unique identification, attributes, technical parameters, 2D/3D view and any other requirement customized. These advances have been made over recent years and foundations for future research established and can be efficiently used in Agriculture for better results.
La concertation semble en passe de devenir une norme en matière de gestion des ressources naturelles et de l'environnement. Pourtant, son impact reste difficile à caractériser, ce qui génère une forme de désenchantement auprès de ses promoteurs. Au cours d'un projet de recherche concertée à La Réunion, nous avons cherché à mieux comprendre comment la concertation influence l'écologie territoriale.
