    Titre: Agricultural land-use patterns and soil erosion vulnerability of watershed units in Vietnam’s northern highlands
    Auteur: Vezina, Karine; Bonn, Ferdinand; Van, Cu Pham
    Sujet: Agricultural Industry -- Analysis ; Land Use -- Analysis;
    Description: Byline: Karine Vezina (1), Ferdinand Bonn (1), Cu Pham Van (2) Keywords: Tropical environment; Watershed; Erosion dynamics; Scaling in space and time; GIS Abstract: Since the mid eighties, agricultural development and increased population growth in Vietnam's northern highlands have modified land use patterns and thus, increased the runoff process and soil degradation induced by water erosion. In the last decade, Vietnamese literature has focused on the computation of soil losses over large areas. Most of these spatial and quantitative soil erosion studies do not consider the impact of agricultural land use diversity (spatial heterogeneity), particularly at the watershed scale, and the annual variability of seasonal landscape factors on soil erosion vulnerability and hence, landscape dynamics. We present an integrated approach combining field measurements and observations, GIS and modeling to determine the spatial and temporal dynamics of soil erosion vulnerability according to watershed units and hence, the impact of physical environment components and agricultural land use patterns on landscape evolution. Tables and graphics showing the cropping systems, the periods within a year, and the watershed units that are most vulnerable are presented. The double cultivation cycles for paddy rice fields not only imply two periods of land preparation and establishment that expose the soil surface to raindrop impacts, but also increased soil management practices that decrease the soil's resistance to detachment. Despite the low levels of soil management practices for the shifting cultivation system, the near absence of soil conservation practices clearly increases their vulnerability. Hence, rainfed cropping systems, mainly soya and cassava, cultivated on sloping lands (hills and mountains) where soil erosion vulnerability is the highest represent the watershed units which are the most prone to soil loss.

    Titre: A comparison of multi-polarization and multi-angular approaches for estimating bare soil surface roughness from spaceborne radar data
    Auteur: Sahebi, Mahmod R; Angles, Joel; Bonn, Ferdinand
    Sujet: Geography
    Description: Soil surface roughness and moisture content both have a significant effect on microwave backscatter to the satellite. The purpose of this work is to evaluate the optimum sensor configuration for existing radar satellites to quantify soil surface roughness. A simulation study using theoretical and empirical models permits the estimation of the sensitivity of the backscatter coefficient to relative variations in soil parameters in terms of radar characteristics. Two different configurations for estimating surface roughness were tested, multi-polarization (co-polarizations) and multi-angular, and the results of the multi-angular configuration provided the best results. A normalized radar backscatter soil roughness index (NBRI) is presented for estimating soil roughness from a multi-angular approach using sensors such as RADARSAT-1. This index was tested using the geometric optics model (GOM) and RADARSAT data. Coefficients of determination of 99% and 83%, respectively, were obtained...
