Le présent mémoire a pour but d’analyser la performance de l’analyse de similarité dans l’outil BAMS (Belgian Agromet Monitoring System) en comparant les résultats de ce modèle avec les valeurs observées. Des calculs du RMSE ont été réalisés afin de comparer les performances avec des modèles connus. Les comparaisons ont été réalisées entre les estimations de rendements mécanistes réalisées par le Website agrométéorologique http://b-cgms.cra.wallonie.be/ et les données réelles ainsi qu’entre les estimations de rendement réalisées via une analyse de similarité et les données réelles. Les comparaisons ont été réalisées sur les cultures de froment d’hiver et l’orge d’hiver de 2002 à 2015 dans les régions agricoles du Condroz, la région Herbagère (Liège) et la région Limoneuse. De plus, une recherche de la variable la plus significative a été réalisée entre 5 variables (ETo, Pluviométrie, LAI, FCOVER et FAPAR) sur les rendements du froment d’hiver dans la région Herbagère (Liège) et la région Limoneuse sur 6 années. Les résultats obtenus montrent un RMSE de 487 kg/ha pour la méthode d’estimation mécaniste utilisée dans les bulletins agrométéorologiques contre un RMSE de 625kg/ha pour l’estimation réalisée avec l’analyse de similarité sur les 5 années historiques les plus similaires par rapport aux données de rendement réelles. Les variables les plus pertinentes sont les variables satellitaires, bien qu’elles n’aient pas donné de résultats probants lors des années exceptionnelles (Sécheresse, dégâts causés par les pluies). Dans le cas des sécheresses, la variable la plus pertinente est l’évapotranspiration. Le modèle d’analyse de similarité comme méthode d’estimation de rendement est donc moins précis que les approches mécanistiques mais très simple d’utilisation et améliorable.

This open access book is focused on the intersection between urban brownfields and the sustainability transitions of metreopolitan areas, cities and neighbourhoods. It provides both a theoretical and practical approach to the topic, offering a thorough introduction to urban brownfields and regeneration projects as well as an operational monitoring tool. Neighbourhoods in Transition begins with an overview of historic urban development and strategic areas in the hearts of towns to be developed. It then defines several key issues related to the topic, including urban brownfields, regeneration projects, and sustainability issues related to neighbourhood development. The second part of this book is focused on support tools, explaining the challenges faced, the steps involved in a regeneration process, and offering an operational monitoring tool. It applies the unique tool to case studies in three selected neighbourhoods and the outcomes of one case study are also presented and discussed, highlighting its benefits. The audience for this book will be both professional and academic. It will support researchers as an up-to-date reference book on urban brownfield regeneration projects, and also the work of architects, urban designers, urban planners and engineers involved in sustainability transitions of the built environment.

Food webs describe the structure of communities and their energy flows, and they represent interactions between species in ecosystems. Recently, we have witnessed rapid development of techniques for both experimental studies and theoretical/computational studies on food webs as well as species interactions. This reprint book is focused on food chains and food webs in aquatic ecosystems, with seven papers published in the corresponding Special Issue of Applied Sciences. The topics include empirical studies on food chains and food webs as well as effects of environmental factors on organisms in aquatic ecosystems.
