The rapid change in the agricultural industry requires the development of new methods of production to guarantee sustainable agriculture. In silico approaches offer the possibility to identify more quickly new systems to tackle current social, political and environmental concerns. Numerous agro-ecosystem functioning models already exist. Nowadays the main(More)
The EU Water Framework Directive (WFD) obliges Member States to improve the quality of surface water and groundwater. The measures implemented to date have reduced the contribution of point sources of pollution, and hence diffuse pollution from agriculture has become more important. In many catchments the water quality remains poor. COST Action 869 was an(More)
The hydrology and water quality in landscapes with hydromorphic soils depends on the space and time extension of wetland areas and on water pathways within the landscape at different scales. To study the control of nitrate fluxes by these areas, investigations were carried out on a detailed study site - the Coët Dan catchment (1200 ha) in Brittany, France -(More)
Many countries are developing models to estimate N emissions in rivers as part of national-scale water quality assessments. Generally, models are applied with national databases, while at the regional scale, more detailed databases are sometimes available. This paper discusses pros and cons of developing regionalized models versus applying countrywide(More)
While many scientific studies show the influence of agricultural landscape patterns on water cycle and water quality, only a few of these have proposed scientifically based and operational methods to improve water management. Territ'eau is a framework developed to adapt agricultural landscapes to water quality protection, using components such as farmers'(More)
Because of the high sorption affinity of phosphorus (P) for the soil solid phase, mitigation options to reduce diffuse P transfer usually focus on trapping particulate P delivered via surface flow paths. Therefore, placing riparian buffers between croplands and watercourses has been promoted worldwide, sometimes in wetland areas. To investigate the risk of(More)
While most hydrological models reproduce the general flow dynamics, they frequently fail to adequately mimic system-internal processes. In particular, the relationship between storage and discharge, which often follows annual hysteretic patterns in shallow hard-rock aquifers, is rarely considered in modelling studies. One main reason is that catchment(More)
