Abstract As of January 31, 2022, ten countries have legislated in favor of active assistance in dying after political, ethical, and social debates. This article reviews the legislative history of these countries (Switzerland, the United States, the Netherlands, Belgium, Luxembourg, Canada, Australia, New Zealand, Spain, and Austria) and describes the framework prescribed by each law to regulate and control the practice of euthanasia or assisted suicide. The aim is to highlight the arguments that are essential for the establishment and implementation of a law, as well as the common eligibility criteria and safeguards, with particular attention paid to the criteria relating… More >

Abstract The objective of this article is to assess environmental equity regarding the accessibility of parks for four population groups (children, older people, low-education individuals, and highly-educated persons) in Ho Chi Minh City (HCMC). To achieve this, two accessibility measures calculated according to network distance in GIS: the distance to the nearest park (immediate proximity) and the enhanced two-step floating catchment area method (availability based on supply and demand). Several regression models were then constructed, with the accessibility measures as dependent variables and the percentages of the four groups as independent variables. The results show that the accessibility of parks in… More >

Abstract Water erosion is a degradation form that results in the stripping of mineral and organic elements from the soil. Due to the impact of meteoric factors (rain, wind) this global phenomenon, soil erosion, affects the productivity of agricultural land. Water erosion is a global phenomenon that affects the productivity of agricultural land. The absence of a protective cover and intense precipitation made the Litani River Basin a vulnerable region to water erosion. Besides, the absence of climate data has brought about erosion hazard mapping using a qualitative method which combines factors such as tillage erosion, infiltration into the rocks, land… More >

Abstract In the humid Mediterranean regions, particularly the NW of Tunisia, the Tessa catchment area is characterized by torrential and irregular rains, combined with significant deforestation, which causes severe erosion that carries away and redistributes the soil. The process of water erosion is very frequent and changes its dynamic aspect according to the evolution and spatial variation of the lithological nature of rocks, the geomorphology of landscapes, the geometry of watersheds and their bioclimatic situation. In this study, an appropriate methodological flowchart was followed by applying the PAP/RAC erosion mapping method, which is based on the principle of weighting the main… More >

Abstract The city of Métlaoui is the most important urban core in Gafsa Mining Basin (BMG) in southwestern Tunisia. Like other BMG cities, it is characterized by a single industrial activity of phosphate enrichment and observes a spatial activity between the “European village” favorized to a certain term and the peripheral cities disadvantaged. Today, this dichotomy is not decreasing; on the contrary, the research reveals real signs of accentuation of this socio- spatial segregation inherited from colonial and post-colonial periods, and the environmental vicissitudes confirm the territorial iniquity. The research methodology has used for the social-spatial aspect heterogeneous data sources and… More >

Abstract The emergence of Web 2.0 is materialized by new technologies (APIs, Ajax, etc.), by new practices (mashup, geotagging, etc.) an, by new tools (wiki, blog, etc.). It is primarily based on the principle of participation and collaboration. In this dynamic, the web mapping with spatial character or simply called Geospatial Web (or Geoweb) evolves by strong technological and social changes. Participatory GeoWeb 2.0 is materialized in particular by mashups among wikis and géobrowsers (ArgooMap, Geowiki, WikiMapia, etc.). The new applications resulting from these mashups are moving towards more interactive forms of collective intelligence. The Geodesign is a new area, which… More >

Abstract While shadow can give useful information about size and shape of objects, it can pose problems in feature detection and object detection, thereby, it represents one of the major perturbator phenomenons frequently occurring on images and unfortunately, it is inevitable. “Shadows may lead to the failure of image analysis processes and also cause a poor quality of information which in turn leads to problems in implementation of algorithms.” (Mahajan and Bajpayee, 2015). It also affects multiple image analysis applications, whereby shadow cast by buildings deteriorate the spectral values of the surfaces. Therefore, its presence causes a deterioration in the visual… More >

Abstract The Sfax phreatic system is an important source of water supply. The latter is constantly threatened by nitric pollution. In order to protect this aquifer, a study of the intrinsic vulnerability has been carried out using the SI (Susceptibility Index) method. The model takes into consideration the various vulnerability criteria governing the process of contaminant transfer. These are geological, hydrogeological, land use, topography, and meteorological factors. In this study, a method derived from the SI model is presented (modified SI). The model is based on an approach that integrates hydrological modeling under Agriflux and GIS. Indeed, the use of GIS… More >

Abstract The geomorphology of the Htab river watershed is mainly guided by the action of the E-W Kasserine fault. This activity influenced the installed hydrographic system. To see the impact of neotectonic on the Htab river watershed, four morphometric indices were applied: the elongation ratio, the hypsometric curve, the hypsometric integral, and the asymmetry factor. The processing and calculation of these indices were based on global DEMs (Digital Elevation Models). The result obtained shows an important link between the activity of the Kasserine fault, the geomorphological behavior of the Htab river watershed and the hydrographic network. Field observations confirmed well these… More >

Abstract Air pollution and road traffic noise are two important environmental nuisances that could be harmful to the health and well-being of urban populations. In Mexico City, as in many North American cities, there has been an upsurge in bicycle ridership. However, Mexico City is also well known for having high levels of noise and air pollution. The purpose of this study is threefold: 1) evaluate cyclists’ exposure to air pollution (nitrogen dioxide) and road traffic noise; 2) identify local factors that increase or reduce cyclists’ exposure, in paying particular attention to the type of road and bicycle path or lane… More >
