Monitoring urban, peri-urban, and rural temperatures, along with greenhouse gas (GHG) emissions, is crucial for understanding local climate dynamics, especially in rapidly urbanizing areas. This study leverages advanced remote sensing techniques environmental analysis to enhance high-resolution Land Surface Temperature (LST) mapping. It further investigates the relationship between LST methane (CH₄) emissions - a significant driver of change their combined impact on Urban Heat...

Land use planning for flood risk reduction has been significantly addressed in literature. However, a clear methodology mitigation oriented land-use and its implementation, particularly developing countries like Lebanon, is still missing. Knowledge on land earliest stages Lebanon. A lack of hazard-informed coupled to random cover pattern evolution characterize the country. In response, this study focuses opportunities, challenges uncertainties resulting from integration into efficient...

Environmental context.Perfluoroalkyl compounds and mercury are of rising concern because their persistency, bioaccumulation potential possibly adverse effects on humans wildlife. In the present study, perfluoroalkyl were quantified in fish liver from high-mountain lakes which contamination originated atmospheric deposition. This study improves our understanding transport deposition these contaminants. Abstract.Perfluoroalkyl (PFCs) total (THg) investigated collected four French alps water...

For nearly a century, the lakes in Jura area (France), as for those throughout northern hemisphere, have been impacted by heavy metal contamination. The were considered long protected and undisturbed owing to agricultural rural nature of their catchment areas thus lack anthropological impacts. Meanwhile, chemical analysis sediments some these particular, Grand-Maclu Saint-Point lakes, has indicated that fact not escaped levels lead measured top 20 centimeters (EF > 2) revealed source...

ecosystems to varying degrees, creating heterogeneity on a global scale (Müller and Bahn 2022).More locally, in Algeria, the north-western region is situated transitional zone between an arid semi-arid climate.This climatic situation directly exposes impacts of climate change.The thermal effects associated processes (evaporation, drought, low and/or intense but short-duration precipitation, etc.) highlight high variability temperatures across territory.

The energy of water masses is a first-order factor that controls the essential physicochemical dynamics body. Its study allows one to understand roots processes occur at water-mass, water-atmosphere and water-sediment interfaces. analysis Thomas Pond in Brenne region gives valuable overview stock evolution on yearly scale. It highlights direct impact this thermal stratification potential for evaporation exchange with atmosphere. remains challenging due complexity factors involved. estimation...

In order to evaluate the impact of potential pollutions on water quality in watershed upstream wadi Boussellem (North-east Algeria), evolution chemical composition waters Ain Zada dam was studied over a period ten years. Using linear model trends and principal components analysis (PCA) methods, have been detected quantified for substances that are connected with fertilizers domestic effluents. An increasing concentration is observed most these substances. The increase 88% COD, 66% BOD5...

The impact of ponds on basins has recently started to receive its well-deserved scientific attention. In this study, pond-induced impacts soil erosion and sediment transport were investigated at the scale French Claise basin. order determine patterns Claise, Coordination Information Environment (CORINE) Soil Water Assessment Tool (SWAT) models used. studied processes was revealed by means land cover change scenarios, using ponded versus pondless inputs. Results show that under current...

Given the absence of soil loss indicators within Land Degradation Neutrality (LDN) framework, this study integrates land cover suitability, erosion and sediment transport as complementary Mediterranean-tailored indicators. The 309 km2 Lebanese Nahr Ibrahim basin was chosen for purpose. suitability determined by combining capability-land maps, while were assessed using CORINE SWAT models, respectively. Under current conditions, following found: a 34.84% suitability; 4% low, 39.55% moderate...

Like many cities in North Africa, limited the south by steppe areas and indeed for some others desert, its demography shows a steep rise, making deep imbalance between highly populated north with low population. This demographic pressure increased considerably during period from 1990-2000, because of extremely unstable political situation. influx was accompanied development new infrastructures (road railway networks) densification economic fabric 2005 onwards which led to Algiers department...

In mountainous areas in recent decades urbanisation has expanded to where low ground adjoins mountainsides that are unstable a number of respects. Periurbanisation mountain basins with sides poses specific problems local players have address. The Lavanchon basin (southeast Grenoble), which is subject very rapid urban growth combined particularly dynamic mountainsides, representative the way activity being brought into closer contact potential hazards. A diachronic study changes land use...

The impact of ponds on basins has recently started to receive its well–deserved scientific attention. In this study, pond–induced impacts soil erosion and sediment transport were investigated at the scale French Claise basin. order determine patterns under current conditions, CORINE SWAT models used. studied processes was revealed by means land cover change scenarios, using ponded versus pondless inputs. Results show that conditions (pond presence), 12.48% basin...

The issue of acidification in lake waters has been the topic numerous scientific studies northern Europe and North America. In recent years, interest spread to southern Asia because similar symptoms have observed (drop pH redox potential, generally accompanied by oxygen depletion). All work on concluded that phenomenon is general affects, different degrees, lakes located at low medium altitudes mountains (the Vosges more recently Jura mountains, France). difference degree often interpreted...

The influence of climate change on water bodies, particularly large ones, has been the subject numerous studies that have demonstrated significant modifications or disturbances hydrological cycle (lower volumes, higher temperatures and disruption thermal stratification, increased direct evaporation), either by interpretation sedimentary records measurements. However, at scale small limnic entities, these changes are barely noticeable only translated a mere human reflection freshness...

L'évolution rapide de la dynamique urbaine dans les secteurs montagneux a certes été bénéfique pour l'homme mais néfaste écosystèmes et leur biodiversité. Véritables espaces récréation loisirs, étangs ont progressivement acquis le label lieux découvertes sensibilisation à l'environnement. Face pression démographique enregistrée sur trente dernières années principales vallées alpines l'extension engendrée, des menaces sérieuses dégradation, voire disparition ces entités environnementales...
