1. Innovation of models across agro-environmental scales

Models are tools for understanding agro-environmental processes like plant production, plant-soil interactions, soil degradation and soil erosion. These models are progressively used in land use planning and assessment of agro-environmental processes. Therefore, it is important that they reflect different spatio-temporal scales and complex process interactions, such as socio-economic driving-forces, soil management practices and geo-ecological processes. However, modelling research still faces the challenge to cover each of the processes affecting agricultural landscapes across spatial and temporal scales. We invite contributions showing innovative tracks for tackling the problems of scale transitions and interdisciplinary model coupling, which help to understand the agro-ecological environment and to provide better tools for spatial planning.
