    Working Paper du GATE 2003-03; The aim of this paper is to show how new location theories can explain the location of industrial activities in rural areas. A survey of recent economic geography models is presented. We aim at highlighting the trade-off firms do when choosing to locate in an urban area or in a low-densely populated area. It is worth taking into account two types of rural areas : rural areas under urban influence and independent rural areas. In the first case, the location of non agricultural activities is mainly explained by the working of the land market. In the second case, labor market has to be taken into account in order to be account for rural industrialization.; L'objectif de ce papier est de mettre en évidence les résultats des nouvelles théories de la localisation qui sont susceptibles d'expliquer la nature des activités industrielles implantées en zones rurales. Une revue orientée de la littérature récente d'économie géographique est présentée, dans laquelle sont mis en évidence les termes de l'arbitrage réalisé par les firmes entre une localisation urbaine et une localisation dans un espace à faible densité de population. Il convient de tenir compte du fait que coexistent deux grands types d'espaces dits ruraux : des zones rurales sous influence urbaine et des zones rurales autonomes. Dans le premier cas, ce sont essentiellement les mécanismes à l'œuvre sur les marchés fonciers qui agissent sur la localisation des activités non agricoles, alors que c'est au travers du fonctionnement des marchés locaux du travail que l'on peut appréhender l'industrialisation dans le cas des zones rurales hors influence urbaine.

    The purpose of the study was to evaluate the use of and suggest possible adjustments to indicators of biodiversity loss for LCA proposed by Chaudhary and Books (2018). For this, we analyzed soybean production in Brazil. Potential damage to biodiversity has been determined for all Brazilian ecoregions: the Amazon; the Atlantic forest; Caatinga; Cerrado; Pampas; and the Pantanal. Two dimensions of assessment were considered - global and regional - in addition to Average-country. An adjustment was proposed for the vulnerability coefficient to the indicators Average-country Brazil: the Regional Species Fragility Index (FI). Two inventories were created using two different functional units: area of production of soybean by ecoregion (year m2); and area corresponding to production of 1 kg of soybean (year m2). Thus, we observed that when the indicators of aggregate values were adopted, the Atlantic Forest was the ecoregion most affected by the crop. Regarding the assessments of the Potential Biodiversity Damage (BD) Global and Regional indicators, the Atlantic Forest and the Amazon were the ecoregions that suffered the highest impacts, mainly on plants, birds and amphibians taxa. Besides, the impacts at the global level were always more expressive than the regional ones. Due to this, we noticed that the results were influenced by the Vulnerability Score (VS). The suitability of the VS for FI is relevant and the adjustment in the equation can be suggested for other regions. Considering the results found here, to prevent regional impacts, technical measures such as extensive farming and crop rotation should be prioritized as impact mitigation actions. However, political measures tend to be more effective at geographic levels when addressing more than one ecoregion, due to the s

    Co-encadrement assuré par le Groupement pour le Développement de la Télédétection Aérospatiale (GDTA) Diplôme : DESS; il s'agit d'un type de produit dont les métadonnées ne correspondent pas aux métadonnées attendues dans les autres types de produit : DISSERTATION; This document proposes a new map of the Eastern Guyana Shield, with the SPOT4-VEGETATION remotesensed datas of the year 2000. A new synthesis method, with the mean value, was applied and compared with the Maximum Value Method (WVC). To prepare this datas for the synthesis, a cloud filter was defined :BSC (BEST Sky Clear). With this results, an ISODATA classification was proceeded, and, produces 25 classes to detail the tropical maist forest with the 1 km low resolution. To valid this result, this document propose a method with the higthresolution datas Landsat 7 ETM+. This method aims to guide the ground truth and goes thoroughly into the description of the moist tropical forest classes. The sample, used to try this method, shows the boundaries and the constraints of this method. This points are debating in the discussion. Finally, the perspectives to develop the method are presented in the conclusion.; Ce document propose une nouvelle cartographie du Bouclier Oriental Guyanais à l'aide d'images satellites SPOT4-VEGETATION de l'année 2000. Une nouvelle méthode de synthèse annuelle, utilisant la valeur moyenne de la radiométrie, a été appliquée et comparée à la méthode du Maximum Value Composite (MVC). A cette occasion, un filtre de nuage a été défini pour préparer les données à cette synthèse : le filtre BSC (Best Sky Clear). Sur la base de ce résultat, une classification ISODATA a été réalisée, produisant 25 classes, et mettant en évidence les différents milieux forestiers des tropiques humides à une résolution spatiale de 1 km. Pour valider la classification, une méthode est proposée utilisant des images hautes résolutions Landsat 7 ETM+. Cette méthode permet de cadrer les vérifications sur le terrain et d'approfondir la définition des classes de forêt tropicale humide. L'échantillon utilisé pour tester la méthode met en évidence les limites et contraintes de la démarche proposée. Ces points sont exprimés dans la discussion. Enfin les perspectives de développements sont abordées dans la conclusion.

    Background: Child malnutrition is a major epidemiological problem in developing countries, especially in African countries. Nutrition education for mothers can alleviate this malnutrition in their young children. The objective of this study was to make a systematic review to assess the effect of intervention programs in nutrition education for African mothers on the nutritional status of their infants. Methods: A bibliographic search was carried out in the PubMed database for clinical trials between November 2012 and 2021. The studies should contain educational programs to evaluate the impact on the infant's nutritional indicators in children under 5 years (food consumption, anthropometry and/or knowledge of nutrition in caretakers). Results: A total of 20 articles were selected, of which 53% evaluated infant's food consumption, 82% anthropometric measurements and 30% nutritional knowledge. In general, nutritional education programs are accredited with some significant improvements in food and nutrient consumption, knowledge and dietary practices in complementary feeding, but only those studies that implemented strategies in agriculture, educational workshops and supplementation obtained reductions in chronic malnutrition figures. Limitations: There is high heterogeneity in the articles included, since the intervention programs have different approaches. Conclusions: Programs that implemented actions of national agriculture or nutritional supplementation reap the greatest benefits in curbing infant malnutrition.

    The article analyses the socio-spatial logic behind the accumulation of foreclosed housing in the hands of large private landlords in the neighbourhoods of all the Catalan cities with over 100,000 inhabitants. Spatial regression and clustering techniques are applied to identify the determinants of the concentration patterns of 10,725 housing units in these cities. The socioeconomic variables, such as income level, percentage of foreign population, level of studies or percentage of unemployed residents, are identified as key explanatory factors of clustering of foreclosures in working-class neighbourhoods. A high presence of previously mortgaged homes is a variable especially relevant in the case of working-class neighbourhoods, but it has no incidence in the case of the medium-high class neighbourhoods. Our findings provide a detailed urban geography of the housing accumulated by banks which, at the same time, correspond to areas in which the vulture funds are focusing their business in the present and in the forthcoming years. New evidences of the spatial logic of the housing crisis and detailed information for the understanding of the new scenarios that have emerged during the post-crisis phase are revealed.

    The article uses passive mobile data to analyse the complex mobilities that occur in a coastal region characterised by seasonal patterns of tourism activity. A large volume of data generated by mobile phone users has been selected and processed to subsequently display the information in the form of visualisations that are useful for transport and tourism research, policy, and practice. More specifically, the analysis consisted of four steps: (1) a dataset containing records for four days-two on summer days and two in winter-was selected, (2) these were aggregated spatially, temporally, and differentiating trips by local residents, national tourists, and international tourists, (3) origin-destination matrices were built, and (4) graph-based visualisations were created to provide evidence on the nature of the mobilities affecting the study area. The results of our work provide new evidence of how the analysis of passive mobile data can be useful to study the effects of tourism seasonality in local mobility patterns.
