L’une des avancées les plus importantes dans le domaine de l’observation de la terre est la découverte des indices spectraux, ils ont notamment prouvé leur efficacité dans la caractérisation des surfaces agricoles, mais ils sont généralement définis de manière empirique. Cette étude basée sur l’intelligence artificielle et le traitement du signal, propose une méthode pour trouver un indice optimal. Et porte sur l’analyse d’images issues d’une caméra multi-spectrale, utilisée dans un contexte agricole pour l’acquisition en champ proche de végétation.
Cet article présente une nouvelle approche à base de logique floue pour évaluer le risque phytosanitaire dans une serre produisant des roses. Le but de cette étude est de fournir à l’agriculteur un indice représentant le risque de présence de nuisible : Western Flower Thrips (WFT) ou Frankliniella Occidentalis, et d’enlever la phase decomptage manuel. Un systéme d’aide à la décision modulaire basé sur la connaissance d’experts a été conçu. Le systéme proposé fournit un facteur de risque en fonction des données météorologiques et statiques.
There is an increasing interest among researchers, practitioners and donors in using agricultural innovation systems approaches to reach development outcomes. Limited practical experiences have been shared on the dynamics of these innovation processes and how project partners have dealt with that. The objective of this paper is therefore to share experiences from a smallholder livestock development project − the imGoats project in Mozambique – by reflecting on the dynamics of innovation processes in the project.
Le Tuy, province de l'Ouest du Burkina Faso est une région soudanienne à forte pression démographique et pastorale où se posent avec acuité des problèmes de fertilité des sols. Face à la dégradation des ressources naturelles, opter vivre dans son milieu natal et s'assurer une bonne production agropastorale nécessite de la part des acteurs des actions concertées. Le projet Fertipartenaires aide les producteurs de cette province à se concerter, à réfléchir à leurs problèmes, proposer et expérimenter des solutions et les évaluer afin d'améliorer leur sécurité alimentaire.
Within the context of the European-funded JOLISAA FP7 project (JOint Learning in Innovation Systems in African Agriculture), several agricultural innovation experiences focused on smallholders were assessed in Benin, Kenya and South Africa. Fifty-six cases were characterised through review of grey literature and interviews with resource persons according to a common analytical framework inspired by the innovation systems perspective. Of these, 13 were assessed in greater depth through semistructured interviews, focus-group discussions and multistakeholder workshops.
in the context of the EU-funded JOLISAA (JOint Learning in Innovation Systems in African Agriculture) project, four local innovation processes involving smallholders in Benin were selected for in-depth assessment: innovation in hwedo agrofishing, integrated soil fertility management (ISFM), rice parboiling and soy value chains. Stakeholders directly involved in the innovation process were interviewed.
In comparison with the other EU (27) countries Innovation capacity indicators in Latvia remain low and considerably underperform. Problems and solutions are illustrated to represent innovation capacity in Latvia. The article consists of the following parts: first - theoretical aspects are selected to describe the essential definition of the analyzed subject. In the second part, experience from abroad is described, at the end – Latvian innovation policy and situation is analyzed and suggestions for further needs are formulated.
The slow rate of agricultural development in Africa can largely be blamed on lack of functional relationships between technology/innovation generation centers, local farming communities, financial institutions and markets. The result has been low penetration of promising innovations/technologies thus, low adoption levels and/ or partial adoption; and limited or no access to markets and financial services by farmers. In general, most of the innovation/technologies developed have not been extensively out-scaled; some of which are not even packaged in user friendly formats.
The poor performance of agriculture in sub-Saharan Africa is known to be largely due to the lack of effective and client- responsive agricultural research and development that could generate appropriate technologies and innovations to stimulate the agricultural development process. As a contribution to address this challenge, the Forum for Agricultural Research in Africa (FARA), with support from the United Kingdom’s Department for International Development (DFID), developed a project for Strengthening Capacity for Agricultural Research and Development in Africa (SCARDA).
Given the diversity and context-specificity of innovation systems approaches, in March 2007 the World Bank organized a workshop in which about 80 experts (representing donor agencies, development and related agencies, academia, and the World Bank) took stock of recent experiences with innovation systems in agriculture and reconsidered strategies for their future development. This paper summarizes the workshop findings and uses them to develop and discuss key issues in applying the innovation systems concept. The workshop’s recommendations, including next steps for the wider
