| The Soil and Water Assessment Tool (SWAT model, 2001 Version) has been applied to the Than lagoon catchment area in order to simulate water discharges and nutrient inputs into the lagoon over a 10 years period (1989-1999), and to provide routing inflows to a previously developed lagoon ecosystem model. The watershed model has been calibrated and validated using measured data available for the two main rivers. The results indicate that the mean annual nitrogen inputs into the Thau lagoon is 117 +/- 57 tons y(-1), with the two main rivers, contributing for 80% of total annual nitrogen export. The variations of outputs to the lagoon are nonetheless important from 1 year to another. Due to the local agricultural practices and a reduced in-stream natural... |

| The GR4H lumped hourly rainfall–runoff model was assessed for its integration in a ridge-to-reef modelling framework. Particular attention was paid to rainfall representation, robustness of parameter estimates and ability to reproduce main runoff features. The study was conducted in four tropical mountainous watersheds in New Caledonia, exposed to intense rainfall events, large annual climatic variations triggered by El Niño oscillation, and wildfires. The inverse distance and elevation weighting algorithm outperformed other classical rainfall interpolation methods under data-limited conditions. The time-span of data needed for robust calibration was site-specific and varied from 6–7 years to 10 years, which may be linked to El Niño events and to... |

| Organic farming is increasingly considered in the European Common Agricultural Policy. Sound evaluations of the effects of policy measures on organic farms in the EU are needed to face the challenges in future policy design. The effects of various policy scenarios on profitability and development strategies of typical organic arable and dairy farms are analysed for the EU countries Germany, Denmark, the United Kingdom and Italy. Based on an approach which integrates simulation modelling and focus groups, profitability of model farms is analysed ex-post for year the 1999 and their potential development simulated until 2008 under Agenda 2000 and three alternative policy scenarios. For each policy scenario potential farm adaptation strategies are analysed.... |
