Cette étude analyse l'évolution de l'occupation du sol dans la métropole AMP en se concentrant sur l'impact de la croissance urbaine. Des techniques telles que les transformations spectrales, les indices spectraux et la géosimulation sont utilisées pour cartographier les changements dans l'occupation des sols et prédire l'étalement urbain d'ici...

Over the last thirty years, the extension of built-up areas has affected all areas of the Aix-Marseille-Provence (AMP) Metropolis. Urban sprawl has been particularly important in generating fragmented urban territories with various forms and spatial patterns. The modelling of the evolution of AMP is fundamental in the context of the...

Ce projet vise à comprendre et à modéliser l'émergence d'une métropole de presque 350000 habitants dans un environnement climatique extrême en arctique sibérien (-50°c à -60°c en hiver), à étudier les outils d'adaptation humains, institutionnels, et d'aménagement mis en place, ainsi que les conséquences liées au changement climatique : fonte du...

In recent decades, population growth has led to rapid urbanisation associated with a land degradation process that threatens soil organic carbon stocks (SOCS). This paper aims to model the interrelationships between SOCS and land use/land cover (LULC). The approach was based on the use of environmental covariates derived from Landsat-5 TM/8 OLI...

The process of metropolisation of Yakutsk is one of the most unique geographic phenomena. Since the end of the Soviet Union, the city of 193000 inhabitants growing fastly to cross in 2021 up to 33000 people covering today almost 1 million square kilometres in the extreme Arctic environment and climate. The population of the Yakutsk metropolis...

In the last twenty years, the Metropolis of Yakutsk has experienced significant changes characterised by intense urban growth, densification, and urban structure changes in a complex geographical environment: extremely low temperature during six to seven months, impacts of permafrost dynamics and relative melting, seasonal exposure to ice...

Climate extremes and their trends in several parts of the world have exacerbated the biophysical susceptibility of agrosystems in semiarid regions. In the Sahel region, this is reflected in a gradual deterioration in the climatic resilience of agrosystems and their ecosystem productivity, with potential losses in cereal yields of up to 27% by...
