Figure conceptuelle NitroScape

Cliquer sur l'image pour agrandir

NitroScape est un modèle intégré ayant pour objectif de simuler les transferts, transformations, pertes  et bilans d’azote réactif (NH3, NOx, NO3-, NH4+, N2O) à l’échelle du paysage (territoire de quelques km2 à dizaines de km2). Il couple des modèles décrivant les processus de transferts et transformations d’azote dans quatre compartiments du paysage : exploitations agricoles, agro-écosystèmes, atmosphère et hydrosphère. NitroScape est couplé à une base de données spatialisée. Il vise à être utilisé en recherche et en partenariat avec le développement agricole pour évaluer l’impact de scénarios agro-environnementaux et proposer des stratégies d’atténuation des émissions d’azote réactif et de gaz à effet de serre et/ou d’adaptation des systèmes de production.

Mots clés : cascade de l’azote, flux d’azote réactif, paysage, modèle couplé
