Keywords: Integrated assessment Stakeholder knowledge Land use model Soil fertility a b s t r a c t In this article we investigate if qualitative soil fertility datasets derived during participatory processes can be combined with a corresponding land use change model (i) to improve the understanding of the social-ecological complexity of land use change and(More)
Agroforestry systems have a large potential to increase systems’ productivity and provide soil conservation in hilly terrain but comprise complex interactions at the crop-soil-tree interface. Modelling can be an operational approach to unravel the later. We used the spatially explicit, dynamic Water Nutrient and Light Capture in Agroforestry Systems model(More)
Hedgerow cropping decreases erosion in hillside agriculture but also competes for water and nutrients with crops. This study combined two methods for an improved understanding of water and nutrient competition at the crop-soil-hedge interface. δ13C isotopic discrimination in plants and soil electrical resistivity tomography (ERT) imaging were used in a(More)
We conducted a field experiment on a 53 %-slope in Northwest Vietnam using 15N-labelled urea to trace its fate in maize (Zea mays) under intensive tillage and fertilization (T1, control) versus maize with Panicum maximum grass barriers (T2), under minimum tillage (MT) with Arachis pintoi as cover crop (T3) or relay cropped with Phaseolus calcaratus (T4).(More)
