Testo completoModern global changes, such as climate change and the sixth mass extinction, are profoundly disrupting our societies and ecosystems. New technologies, including machine learning, are both aggravating factors and potential means of mitigating the challenges posed by these changes. In 2015, the United Nations established the Sustainable Development Goals to assess the ecological impact and the risks for populations, revealing that the countries of the South are the furthest from achieving the objectives of this framework. Countries with limited digital infrastructures deploy less machine learning models, encountering a problem of context shift due to inconsistency between training and deployment data. In computer vision, this shift is exacerbated by the absence of data from southern countries in the training sets, leading to reduced model performance.In this thesis, we bridge the gap between artificial intelligence for sustainable science and the inclusivity of computer vision systems. We show how previous approaches to demonstrating the lack of inclusivity of current vision systems have overlooked important aspects of the problem, such as the formalisation of geographical bias and the metrics that reflect its impact. This has led us to propose a protocol for formalising bias, based on the identification of a source, a type and an impact in order to characterise it. This protocol has been implemented for geographical bias, initially on synthetic data. As known synthetic databases do not have a geographical bias, we create synthetic datasets with geographical biases, inspired by previous synthetic modifications of the MNIST database. We use these to test the implementation of our protocol and demonstrate its usefulness. We then experiment with the protocol on real data for characterising western bias in vision systems, and find that the results obtained are different from those expected, going against observations in previous academic work. We carry out a visual analysis of these results at different levels of granularity in an attempt to understand them and to propose possible themes for future research. In the end, we highlight the presence of concomitant biases, elements that make up the geographical bias but have different impacts that the main entity. These concomitant biases prevent the characterisation of the geographical bias by influencing the predictions of the models.We therefore show how the problem of characterising geographical bias is more complex than it might at first appear, what the current pitfalls are and what avenues are being pursued to remedy the problems encountered. Overall, we offer the scientific community tools to better understand the problems of deploying models in developing countries, in order to better understand the challenges of these deployments for applications in sustainable science

Testo completoThe upper basin of the oued Djemaa which includes to the mountain of Djurdjura is affected by an important morphogenesis. The ground movements introduces a large variety in the study area and play a preponderant role in the evolution of mountainsides. The geomorphology detailed study an investigation into the local populations, geotechtonic and analyses it sedimentology of displaced trainings allows us to do ground typology movement and to chow theire development factors and their location. The big rainfalls of winter and sprinter are the origin of these ground movements and gully erosions, but exposition and lithology allow to understand different forms on northern and southern slope. Human activities play more and more an important role in morphogenesis acceleration. In this study, a geographical information system has been used to provide degradation maps of risks of which are tools for planning and management of soil using in the upper basin of the oued Djemaa. He allows to cross vulnerability witch vagary. The result of these crossroads which we codified results in a total map of risk levels

Testo completoThe Pays d’Auge plateau hillslopes (Normandy, France) are widely affected by instability processes. In spite of an actual risk, few studies were engaged on these complex phenomena in this smooth topography area. This research aims to complete the limited knowledge about the local instability processes and to develop a landslide susceptibility mapping strategy. Two main objectives are guiding the work : (1) observation and characterization de the instability phenomena (inventory, typology and geomorphological mapping) ; (2) landslide susceptibility mapping at the 1/50. 000 and at the 1/10. 000 scale. We obtained a detailed landslide typology for the continental part of the Pays d’Auge plateau. This was used as a basis for several landslides inventories at different scales. Datasets representing the landslide predisposing factors were acquired with a particular attention paid on the quality, the cost and the scale fitting of the data. The work was focused on the comparison between “expert”, “semi-expert” and probabilistic approaches to map the landslide susceptibility. The results show that probabilistic approaches can be used complementarily to the usual expert methods and can help in selecting more appropriate landslide predisposing factors, even if the method is widely influenced by the quality of the input data

Testo completoThe present study is focused on complex rotational-translationnal landslides occurring along the coastal slopes of Calvados. The landslides kinematics is characterized by slow and permanent activity ranging from a few millimeters to a few centimeters per year. The slow velocity can be affected by major accelerations explained by combined triggering factors as prolonged rainfall. The complexity of these phenomena is linked to their temporal and spatial heterogeneity dynamics. Furthermore, their location in urban coastal environment induces high socio-economic issues. For better understanding of these complex landslides processes, the study focused on: (1) the internal structure characterization with the help of geophysical, geotechnical and geomorphological data; (2) the hydrological and hydrogeological specificities of the slope with hydrodynamics characterization; (3) the kinematics of the landslides measurement from monitoring network to put in forward the spatial and temporal heterogeneities; (4) the identification of critical piezometric or rainfall threshold inducing acceleration; (5) the assessment of consequences and the risk management linked to several acceleration crisis. And finally the research focused on the actual element at risk and landslide extension possibilities
