One of the challenges of eco-efficient agriculture is the development of operational farming practices to increase the level of agricultural production, maximize the efficiency of resource use and reduce environmental impacts. Based on the efficiency frontier concept and the decomposition of resource use efficiency, we used a three-quadrant framewo...
Pour obtenir et maintenir une eau potable qui réponde aux normes, les collectivités locales ont le choix entre deux types d’actions : préventives par la mise en place de périmètres de protection de captages d’eau potable (PPC) ou d’aires d’alimentation de captages (AAC), ou/et curatives qui consistent à traiter les eaux pour satisfaire les exigence...
Cropping system simulation can address the complex and interactive nature of resilience and allows for biological (crop growth and development), physical (soil-water dynamics), chemical (soil carbon and N turnover), and management related (e.g. crop choice, applications of nitrogen fertilizer, timing of sowing) aspects of resilience to be quantifie...
The aim of this work is to calculate and compare the economic efficiency indices of irrigated farms and the level of optimisation of irrigation water used for the main crops of the Gharb area. To this end, a Data Envelopment Analysis (DEA) model was used to calculate efficiency indices. The survey covered 49 farms with different crop systems (veget...

Ce mémoire en vue de l'obtention de l'Habilitation à Diriger des Recherches entre dans le cadre du programme national de la conservation des ressources génétiques du peuplier noir (Populus nigra L., famille des Salicaceae), espèce pionnière emblématique des forêts alluviales.
Climatic events predicted for this century should involve drier and warmer summers, such as those that occurred in 2003 and 2005 in France. The higher temperatures could become a limiting factor for the regeneration of Populus nigra L. species. During establishment and development in summer period, seedlings must be able to resist high temperatures...
We present results and insights gained from the characterization of the hydraulic architecture of eight field-grown Populus deltoides × Populus nigra genotypes, already known to differ in terms of growth performance, water-use and xylem anatomy (Marron et al. 2005, Monclus et al. 2005, 2006; Fichot et al. 2009). Under well-watered conditions, we pr...
