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.
Agriculture continues to be the backbone of the economy of Rwanda contributing more than a third of the country’s GDP. The government of Rwanda with collaboration of researchers and its population has to stress on policies and projects to stimulate productivity as they are many corners in agriculture sector to be improved. Bolstering the livelihoods in developing countries is feasible through maintenance of food sovereignty and safety by increasing productivity.
Boll guard I & II were introduced in 2002 and 2006 by Mahyco Monsanto with Genetic Engineering Appraisal Committee, Govt. of India. Indian cotton farmers adopted Bt hybrid cotton between 2002-2013 reaching 92% of the cotton area and 95% of the production, replacing conventional hybrids/ varieties of all the species in both rainfed and irrigated conditions. Bt hybrid cotton was presumed to produce record highest average productivities in India and other major cotton growing countries also in 2007 and 2012 with a decline after 2008 due to excess rains. Farmers invested Rs.
This study explores one of the most important questions for alleviating poverty in sub-Saharan Africa, why are advancements in agricultural technology not taking root in this region? Using data from deep interviews of 42 small-scale farmers in Ghana and Cameroon, a conceptual analysis of drivers and factors of agricultural technology adoption in this region is made and represented as causal loop diagrams. Interviews also provide a basis for weighting factors that farmers consider before adopting a new technology.
Dans un contexte de rareté de l'eau, les pays de l’Afrique du Nord Ouest (NWA) consomment 70% de leurs ressources en eau renouvelables. La surexploitation des eaux souterraines, estimée à près de 50%, est devenue un défi majeur pour la conception et la mise en oeuvre de politiques durables d'allocation et de gestion de l'eau dans la région. Cette situation menace l'avenir de l'irrigation, où la contribution des eaux souterraines est déterminante : 100 % en Libye, 68 % en Tunisie, 54 % en Algérie.
This synthesis report presents the outputs of the workshop organised by CTA at its headquarters in Wageningen, The Netherlands, 15-17 July 2008. The outputs are presented in two main parts, each corresponding to one of the workshop objectives, and ends with a section on the way forward as suggested by the workshop participants. It also includes a first attempt to come to a consolidated generic framework on AIS performance indicators, based on the outputs of the different working groups.
The 2014 Annual workshop of the CGIAR Consortium CapDev Community of Practice was held from September 10–12, 2014 at CGIAR Consortium Headquarters, Montpellier, France.The workshop was planned by a CapDev Convening Committee comprised of Iddo Dror (ILRI), Diana Brandes (Livestock & Fish), Per Rudebjer (Bioversity), Simone Staiger (CIAT), Mehmood Hassan (ICRAF), Javier Ekboir (ILAC), Alain Vidal/Luis Solorzano (Consortium Office) and a facilitator Nadia Manning-Thomas.
This paper contributes to the ongoing discussion in the scientific literature on the advantages and disadvantages of privatization of extension and advisory services and the shift from thinking in terms of the traditional Agricultural Knowledge System towards a broader Agricultural Innovation System.
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.
