Human activities and climate change constitute the contemporary catalyst for natural processes their impacts, i.e., geo-environmental hazards. Globally, catastrophic phenomena hazards, such as drought, soil erosion, quantitative qualitative degradation of groundwater, frost, flooding, sea level rise, etc., are intensified by anthropogenic factors. Thus, they present rapid increase in intensity, frequency occurrence, spatial density, significant spread areas occurrence. The impact these is...

The rapid advent in geoinformation technologies, such as Earth Observation (EO) and Geographical Information Systems (GIS), has made it possible to observe monitor the Earth’s environment on variable geographical scales analyze those changes both time space. This study explores synergistic use of Landsat EO imagery Support Vector Machines (SVMs) obtaining Land Use/Land Cover (LULC) mapping quantifying its spatio-temporal for municipality Mandra–Idyllia, Attica Region, Greece. area is...

Natural resources degradation poses multiple challenges particularly to environmental and economic processes. It is usually difficult identify the degree of critical vulnerability values in affected systems. Thus, among other tools, indices (composite indicators) may also describe these complex systems or phenomena. In this approach, Water Land Resources Degradation Index was applied fifth largest Mediterranean island, Crete, for 1999–2014 period. The uses 11 water soil related indicators:...

This paper explores the resilience of education systems in face challenges that have arisen wake Covid-19 pandemic and emphasizes urgent need for educational institutions to prepare uncertainties unforeseen challenges. The highlights shortcomings ensuring equity disadvantaged students during pandemic, limitations current research on systems, argues consider system alongside teachers. Drawing insights organizational social-ecological approaches resilience, this schools ultimately depends...

Efficient and sustainable exploitation of water resources requires the adoption innovative contemporary management techniques, a need that becomes even more demanding due to climate change increasing pressures coming from anthropogenic activities. An important outcome this reality is qualitative quantitative degradation groundwater, which clearly indicates exploit surface runoff. This study presents an integrated Geographic Information System (GIS)-based methodological framework for...

Floods are natural hazards with negative environmental and socioeconomic impacts at a local regional level. In addition to human lives, facilities, infrastructure, flooding is potential threat archaeological sites, all the implications for cultural heritage of each country. Technological developments recent years, particularly concerning geospatial technologies (GIS, Remote Sensing, etc.), have brought novel advantages hydrological modelling. This study uses geoinformatics quantify flood...

Nowadays, the evaluation of coal deposits becomes crucial, due to many uncontrollable factors, which affect energy sector. A comparative is essential for their hierarchical classification regarding sustainable exploitation, when compared other or competitive fuels, may be used as alternative solutions electricity generation. In this paper, a method spatial analysis and lignite deposit proposed, by creating four key indicators via GIS analysis, are then aggregated applying weighted linear...

Natural resources are gradually coming under continuous and increasing pressure due to anthropogenic interventions climate variabilities. The result of these pressures is reflected in the sustainability natural resources. Significant scientific efforts during recent years focus on mitigating effects Hence, there a need develop specific indices indicators that will reveal areas having highest risks. Water Land Resources Degradation Index (WLDI) was developed for this purpose. WLDI consists...

In Urban Planning (UP), it is necessary to take under serious consideration the inhibitors of spread a settlement in specific direction. This means that all those parameters for which problems may arise future should be considered. Among these are geo-hazards, such as floods, landslides, mud movement, etc. study deals with UP taking into account possibility widespread flooding expansion areas. There large history Greece, accompanied by significant number disasters different types land...

One of the most important natural processes, with significant environmental impacts, is soil erosion. The aim this paper to evaluate and assess erosion vulnerability geological formations constituting Sperchios River basin, in Eastern Central Greece, as well distinguish locate areas such risk estimate it. developed methodology based on Multi-Criteria Evaluation (MCE), implementation Weighted Cartographic Overlay (WCO) technique Geographic Information Systems (GIS) environment. By applying...

Frost is one the most significant hazards affecting various aspects of human lives including infrastructure, agriculture, economy and biodiversity. Water bodies are key factors controlling temperature fluctuations frost. This study introduces a contemporary method for identifying spatially analyzing frost risk also explores its spatial correlation with water bodies. The proposed technique based on coupling freely distributed geospatial data time series land surface (LST) from Moderate...

Soil moisture (SM) is the primary variable regulating soil temperature (ST) differences between daytime and night-time, providing protection to crop rooting systems against sharp sudden changes. It also has a number of practical applications in range disciplines. This study presents an approach incorporating effect ST for accurate estimation SM using Earth Observation (EO) data from NASA’s SMAP sensor, one most sophisticated satellites currently orbit. Linear regression analysis was carried...

Forest fires can result in loss of life, damage to infrastructure, and adverse environmental impacts. This study showcases an integrated approach for conducting high-detail fire risk assessment supporting strategic planning management events peri-urban areas that are susceptible forest fires. The presented methodology encompasses hazard modeling, vulnerability exposure assessment, situ observations. Numerous scenarios were tested, simulating the spatiotemporal spread under different wind...

SWOT (Strengths, Weaknesses, Opportunities and Threats) analysis is a useful tool for sustainable development decision making about environmental planning water resources management. This was applied in order to evaluate the of wider area Sperchios River. River basin, with an average altitude approximately 810m, covers 2116 km2. The river recharged by many streams permanent periodic flow discharges Maliakos Gulf. steep slopes, which are present within 2/3 total length course, form rather...

Spatial modeling and evaluation is a critical step for planning the exploitation of mineral deposits. In this work, methodology investigation multi-seam coal deposit spatial variability proposed. The study area includes Klidi (Florina, Greece) lignite which suitable surface mining. analysis based on original data 76 exploratory drill-holes in an 10 km2, conjunction with geological geomorphological deposit. analytical methods include drill-hole appropriate algorithm, principal component...

Research efforts focused on developing a better understanding of the evolution mortality over time are considered to be significant interest—not just demographers. Mortality can expressed with different parameters through multiparametric prediction models. Based Beta Gompertz generalized Makeham (BGGM) distribution, this study aims evaluate and map four such for 22 countries European Union, period 1960–2045. The BGGM probabilistic distribution is multidimensional model, which predict using...

In 2007, the European Parliament established Directive 2007/2/EC for Infrastructure Spatial Information in Community (INSPIRE).
