Stakeholders involved in actions to reduce the use and the impacts on the environment or human health of pesticides need operational tools to assess crop protection strategies in regard to these impacts. I-Phy3 brings together all improvements introduced since the first version of the indicator to better meet user's needs and requirements of integr...
The participative approach ABC'Terre (attenuation of greenhouse gas emissions balance integrating soil carbon storage at the territory scale) tends to establish a plan of action in order to reduce the carbon footprint of the cropping systems of a territory. It has been already applied on 4 pilot territories in the frame of ABC'Terre 2A R&D project,...
Agriculture can significantly contribute to climate change mitigation by storing carbon in plants and soils. Worldwide, soil contains about three times as much organic carbon as plants and twice as much as the atmosphere. However, arable soils, especially in the most intense cropping regions have lost much of their soil carbon. The knowledge on man...
Stakeholders need operational tools to assess crop protection strategies in regard to environmental impact. The need to assess and report on the impacts of pesticide use on the environment has led to the development of numerous indicators. However, only a few studies have addressed the predictive quality of these indicators. This is mainly due to t...
Ce numéro comprend les articles issus du colloque de restitution Ecophyto Recherche « Des outils et des dispositifs pour éclairer les décisions, explorer les possibles et accompagner la transition vers des systèmes économes et multi-performants », qui s’est tenu à Saint-Malo, du 22 au 24 mars 2017.
Reducing runoff and soil erosion in the Alsace using a territorial agronomic approach
About one third of the agricultural land in the Alsace has a moderate to strong erosion sensitivity and this situation continues to degrade. The evolution of erosion controlling factors in the Alsace shows (a) an increase of the surface of rainfall exposed arable...
Le modèle AMG-SIMEOS (pour la simulation des évolutions des stocks et teneurs en matière organique du sol) utilise la densité apparente à l’entrée. Cette donnée, pas disponible dans les bases de données du Référentiel Régional Pédologique (RRP), doit être estimée en s’appuyant sur une méthode fiable et sensible aux paramètres disponibles dans le RR...
Surface runoff and erosion represent major processes of pesticides
transport from agricultural lands to aquatic ecosystems. Even if
pesticide runoff models have been steadily improved in recent years,
they remain only partially successful in correctly predicting pesticides
transfers to surface waters. This could be partially explained by the
limite...
In order to propose relevant pesticide mitigation strategies within agro-systems, i.e. grass strips or storm basins, it is necessary to identify the areas that mostly contribute to pesticide losses in surface water. At the agricultural catchment scale, this identification requires assessing the hydrological connectivity between plots and the river...
Soil erosion rates depend in many ways on soil and soil surface characteristics which vary in space and in time. To account for spatial variations of soil features, most distributed soil erosion models require data input derived from soil maps. Ideally, the level of spatial detail contained in the applied soil map should correspond to the objective...
Conservation tillage (CT) constitutes one way to limit on- and off-site impacts of soil erosion. Literature analysis suggests that CT is more effective in reducing soil erosion than surface runoff. The effect on runoff mitigation may be rather limited and in some cases, CT causes runoff to increase compared to conventional tillage systems. From the...
Prognosis of the development of the nitrate pollution in the Upper Rhine Graben Aquifer shows a decline of concentrations due to significant reduction of nitrate input with recharge in the past. However, the estimation of historical input is rather unsure, therefore the predictions should be verified-by surveys in the next years. Even in 2050 a goo...
A system of hydrological, agricultural and socio-economical models "MoNit" is used to analyze the past development of groundwater nitrate pollution of the Upper Rhine Graben aquifer within an area of approx. 4 300 km 2. The input of nitrate to groundwater with recharge from precipitation was simulated using a large scale nitrate balance model. In a...
The large groundwater aquifer in the Upper Rhine Valley shows a high nitrate load due to various reasons. To decrease the input of nitrate a series of regulations are currently in force, and first steps are being taken in the German as well as in the French part of the Upper Rhine Valley towards their implementation. Furthermore, changing directive...
This paper explores a scale‐adapted erosion mapping method which aims at a rapid assessment of field erosion and sediment transport pathways in catchments up to several square kilometres and compares the results with the output of a well‐known erosion model (LISEM). The mapping method is based on an event‐defined classification scheme of erosion in...
The objective of this study was to estimate the potential effects of changes in climate and land use on the mobilization of fine sediment and the net transport of wash load from the upstream basin to the lower Rhine delta. For this purpose, a suite of geographical information system-embedded models was developed that simulates the production, and t...
The delivery of detached sediment by overland flow from disjunct agricultural fields to stream channels has important impacts on the river (eco)system and surface water quality. The degree of connectivity between overland flow source areas and the permanent drainage network is affected by the presence of small-scale man-induced linear elements, suc...
This paper discusses a model which simulates dune development resulting from aeolian saltation transport. The model was developed for application to coastal foredunes, but is also applicable to sandy deserts with transverse dunes. Sediment transport is calculated using published deterministic and empirical relationships, describing the influence of...

This paper discusses a two-dimensional second-order closure model simulating air flow and turbulence across transverse dunes. Input parameters are upwind wind speed, topography of the dune ridge and surface roughness distribution over the ridge. The most important output is the distribution of the friction velocity over the surface. This model is d...
During the last three decades, damage by rainfall induced accelerated erosion with associated off-site effects (flooding, sedimentation), has increased in Dutch South-Limbourg. Damage affects a hilly area with 40,000 ha of loess soils. In 1985, a plot study started to evaluate the effects of various conservation cropping systems of fodder maize on...
In the framework of a climate change research project, an approach and preliminary results are presented of modelling the suspended sediment supply to the drainage network of the River Rhine. Concepts of the GAMES model are used as a basis. In the model, the amount of mobilized sediment that actually reaches the stream network depends on the proxim...

ABSTRACT
This paper discusses a model which simu...
For four years, runoff and soil loss from seven cropping systems of fodder maize have been measured on experimental plots under natural and simulated rainfall. Besides runoff and soil loss, several variables have also been measured, including rainfall kinetic energy, degree of slaking, surface roughness, aggregate stability, soil moisture content,...
Accurate estimations of water retention and detention are needed to simulate surface runoff and soil erosion following a rainfall event in a catchment. Several equations to estimate the amount of surface depressional storage, the fraction of the soil surface covered by water and the amount of rainfall excess needed to start surface runoff have been...
This paper discusses aspects of grass vegetation in relation to soil erosion control. By means of a literature research, four options for using grass vegetation were recognized, each having its own requirements concerning maintenance, vegetation characteristics and field layout. The main filter mechanisms, application in the field and effects on ru...
Over a two-year period, rainfall, runoff and sediment output were measured in six small agricultural catchments (3-10 ha) in south Limburg (the Netherlands). In this paper, results of the measurements are presented and processes that determine surface runoff and sediment yield during winter and summer rainfall are identified. The measurement result...
Over a two-year period, rainfall, runoff and sediment output were measured in six small agricultural catchments (3–10 ha) in south Limburg (The Netherlands). These measurements were needed for validation of an erosion model for South Limburg (LISEM). In this paper, results of the measurements are presented and processes that determine surface runof...
Surface runoff may be generated when the rainfall intensity exceeds the infiltration capacity, or when the soil profile is saturated with water. Indications exist that both types of overland flow may occur in hilly agricultural loess regions. Here, for a loessial hillslope under maize in the southern part of The Netherlands, it was shown, with pres...
This paper deals with the effect of rainfall on the process of wind erosion of beach sands and presents results from both field and wind tunnel experiments. Although sediment transport by splash is of secondary importance on coastal dunes, splash–saltation processes can move sediments in conditions where no motion is predicted by aeolian processes....
In dit rapport wordt ingegaan op de modellering van sedimenttransport door de wind op het strand en in de zeereep. Het doel is te komen tot een model waarmee effecten van beheersmaatregelen op de morfologie van de zeereep kunnen worden voorspeld, ten einde het zeercepbeheer te optimaliseren. Dit rapport beschrijft (a) versie 0.0 van het SAFE-model...
For the development ofthe Limburg Soil Erosion Model (LISEM), a validated hillslope hydrology module was needed. Therefore, hydraulic heads were monitored on four hillslopes in the southern part of The Netherlands during the years 1992 and 1993. The hydraulic heads were recorded automatically , using stand-alone measuring devices. Simultaneously, r...
Soil detachment and transport by wind- driven rain differs from that by rainless wind and from that by windless rainfall. This study deals with field measurements of particle movement during periods in which rain and wind coincide. The effect of rainfall on the movement of soil particles by wind is analyzed using a sediment sensor called SALTIPHONE...
Questions
Question (1)
I am interested knowing more about albedo impacts on soil moisture. Albedo thus as a lever in order to limit climate change impacts on crop production. There is quite some literature on soil moisture impacts on albedo, but not the other way around. And here I am interested in methods to estimate how albedo impacts actual plant available water (not only soil moisture close to the surface). Does anyone knows about papers on this subject?
Many thanks in advance!
Paul
