[Termes IGN] utilisation du solRésumé : (Auteur) The family of outranking methods includes a set of well-known and popular decision-aid methods. Heterogeneous variables of various scales can be introduced, and data transformations are not required. But it is also recognized that these methods are subject to computational limitations with respect to the number of decision alternatives. Dealing with large raster datasets and considering every raster cell a location alternative, these methods reach their computational limits quickly. This paper discusses these computational limits and presents an iterative approach which enables a modeller to easily and transparently apply outranking methods for land-suitability assessment with practically no limit in the sizes of the raster datasets. An example using the PROMETHEE outranking approach is performed.

[Termes IGN] utilisation du solRésumé : (Auteur) Among the various natural hazards, mass movements (MM) are probably the most damaging to the natural and human environment in Mediterranean countries, including Lebanon which represents a good case study. This research deals with how to use Geographic Information Systems (GIS) for establishing the relationships between MM occurrence and different factor terrain parameters over a representative region of Lebanon. Parameters expressed by: 1-ancillary data like lithology, proximity to fault zone, soil type, land cover/use, distance to drainage line and rainfall quantity, and 2-derived data like slope gradient and slope aspect, were correlated with MM using GIS-approaches. The MM were first detected through visual interpretation of two stereo-pairs of SPOT 4 images (anaglyph) at 10 m resolution. This study indicates, depending on bivariate Remote Sensing and GIS statistical correlations (Kendall Tau-b correlation), that the lithology is the most influencing factor on MM occurrence. It also shows that statistical correlations to mass movements exist best between factors at the following decreasing order of importance: lithology-proximity to fault line, lithology-soil type and lithology- distance to drainage line at 1% level of significance, and soil-land cover/use, slope aspect-land cover/use, and soil-slope gradient at 5% level of significance. These correlations were verified and checked through field observations and explained using univariate statistical correlations. Therefore, they could be extrapolated to other Mediterranean countries having similar geoenvironmental conditions.

[Termes IGN] utilisation du solRésumé : (Auteur) Iowa is the leading agricultural state in the USA. Increasing suburban and rural development as well as industrial and commercial growth threaten Iowa's unique farmlands and cause their rapid conversion into other land uses. Thus, detecting spatial patterns of cropland loss and predicting future loss are important issues for better agricultural planning and management. This study provides a unique approach for monitoring and modeling cropland loss in Iowa, focusing on differences between rapidly growing urban counties and rural depopulating counties. The monitoring of farmland loss is based on classified 1984, 1992, and 2000 two-season Landsat Thematic Mapper (TM) and Enhanced Thematic Mapper Plus (ETM+) satellite imagery. The modeling approach used joint cellular automata - Markov simulation procedures to predict cropland loss for 2008 and 2016. Mapping of cropland dynamics, using remotely sensed data in urban and rural counties between 1984 and 2000, revealed that there was a significant decline of croplands in Iowa. The simulation of land cover changes for 2008 and 2016 showed continuing decline of croplands in both urban and rural counties. The results of the study can be used by local planners and managers for the development and application of sustainable agriculture practices in Iowa.

[Termes IGN] utilisation du solRésumé : (Auteur) Many parts of the world with young mountain chains, such as the Himalayas, are highly susceptible to landslides. Due to general ruggedness and steep slopes, roads provide the only way of transportation and connectivity in such terrains. Generally, landslide hazards are overlooked during route planning. In this study, in a test area in the Himalayas, various thematic layers, viz. landslide distribution, landslide hazard zonation, landuse/landcover, drainage order and lithology are generated and integrated using Remote Sensing GIS techniques. The integrated data layer in raster form has been called a 'thematic cost map' and provides an estimate of the cost of route development and maintenance. The relative cost assignment is based on experts' knowledge. Route planning is based on neighbourhood analysis to find various movement possibilities from a pixel to its immediate neighbours. A number of patterns such as those analogous to movements in chess games have been considered. Two new neighbourhood patterns, named here Knight31 and Knight32, have been conceived in addition to commonly used Rook, Bishop and Knight patterns. The neighbourhood movement cost for moving from one pixel to a connected neighbour has been calculated for a 7 x 7 pixel window considering distance, gradient cost and thematic cost. Dijkstra's algorithm has been applied to compute the least-cost route between source and destination points. A few examples are presented to show the utility of this approach for a landslide-safe automatic route planning for a highly rugged hilly terrain.

[Termes IGN] utilisation du solRésumé : (Auteur) La conception de mesures agri-environnementales efficaces nécessite de comprendre comment se construit le paysage agricole. Pour connaître les raisons des décisions des agriculteurs et leur marge de manoeuvre vis-à-vis des changements qui leur sont demandés, nous avons mené une enquête dans 12 exploitations agricoles des marais de Moëze pratiquant grande culture et élevage. Les agriculteurs expliquent leurs décisions d'usage des parcelles par leurs contraintes physiques, notamment excès d'eau et instabilité du sol des terres de marais, par les caractéristiques globales du territoire d'exploitation, par leurs choix stratégiques et l'organisation du travail. La prééminence des contraintes de milieu dans les marais, structure le paysage et limite la marge de manoeuvre des agriculteurs.
