Special Issue Information

Dear Colleagues,

Geological settings and earth processes influence the occurrence of natural hazards like landslides, floods, or droughts, which have numerous impacts on humans and their environments. At the same time, human activities and dramatic population growth significantly increase the impact of climate and land use change on the physical environment, causing the deterioration of human health and ecosystem services, the pollution of water, soil, and air, the imbalance of biogeochemical cycles, and enormous waste production. In addition, the overexploitation of mineral resources deteriorates huge areas of land, produces enormous mine waste, and pollutes sensitive natural resources.

Over the last several decades, vulnerable areas such as fertile soils around rivers prone to flooding or coasts vulnerable to tropical cyclones were regularly affected by extreme events, having large socio-economic and environmental impacts affecting many sectors. These multi-faceted impacts occur both in arid and semi-arid regions, but also in regions where water availability has never before been a major concern. In addition, many water systems used for water supply and irrigation are already under substantial pressure from overexploitation or pollution, and the demand for water resources is increasing remarkably.

Improved knowledge on how to identify and mitigate environmental problems caused by natural hazards and humans and how to help land-use planners and policy makers to balance needs for land and resources with their availability is pivotal to achieve sustainable development. Although substantial scientific progress has been made over the last several decades on natural hazards preparedness, monitoring and forecasting, the environmental impact assessment of mining and mineral processing, and water resources management and planning under the changing climate, there are still research gaps in this area that need to be tackled. This Special Issue aims to contribute to advancing the scientific knowledge on the assessment of the environmental and socio-economic impacts of natural and anthropogenic hazards on soil and water. In particular, this Special Issue will focus on:

  • Environmental and socio-economic impacts triggered by natural or anthropogenic hazards at different scales, taking into account economic, political, and social factors;
  • Impact monitoring using ground and/or remotely sensed techniques;
  • Impact of mining and mineral processing on environment and human health;
  • Pollutant leaching through soil and unsaturated zone from different land-uses in both time and space, taking into account uncertainty in model prediction;
  • Integrated decision-making and management modelling systems for sustainable water management strategies;
  • Geological aspects of waste management; and
  • Characterization and remediation of contaminated soil and groundwater.

Vector borne diseases have been related to various environmental parameters and environmental changes like climate change, which impact their propagation in time and space. Remote sensing data have been used widely for monitoring environmental conditions and changes. We hypothesized that changes in various environmental parameters may be reflected in changes in mosquito population size, thus impacting the temporal and spatial patterns of vector diseases. The aim of this study is to analyze the effect of environmental variables on mosquito populations using the remotely sensed Normalized Difference Vegetation Index (NDVI) and Land Surface Temperature (LST) obtained from Landsat 8, along with other factors, such as altitude and water covered areas surrounding the examined locations. Therefore, a Multilayer Perceptron (MLP) Artificial Neural Network (ANN) model was developed and tested for its ability to predict mosquito populations. The model was applied in NE Greece using mosquito population data from 17 locations where mosquito traps were placed from June to October 2019. All performance metrics indicated a high predictive ability of the model. LST was proved to be the factor with the highest relative importance in the prediction of mosquito populations, whereas the developed model can predict mosquito populations 13 days ahead to allow a substantial window for appropriate control measures.

As a specific type of landscape and aquifer, karst is developed in soluble carbonate and evaporitic rocks and is of great importance for humanity. It covers more than 15% of Earth’s ice-free land and its aquifers provide about 10% of the world population’s drinking water. However, in general, its importance is not adequately supported by monitoring. Due to very dynamic karst regimes, in many countries, monitoring networks and their technology must be enlarged and improved, in terms of both the quantity and quality of water. The article discusses the current state of monitoring in legislation and water practice, as well as its importance in preventing water pollution, ensuring water provision to dependent ecosystems and preparing adaptation strategies to mitigate the negative effects of climate changes. Karst aquifers’ heterogeneity, high vulnerability to pollution and their very dynamic regimes require a more frequent observation of discharge and water quality parameters than any other aquifer system. There is also a need for installing sophisticated monitoring equipment, which enables remote observation of changes in dynamic karst systems. Improving monitoring and creating an early warning system would have a direct and positive effect on water management and might also be able to prevent uncontrolled groundwater extraction and deterioration of water quality.

The Mediterranean freshwater resources, mostly represented by groundwater, are under increasing pressure due to natural and anthropogenic factors. In this study, we investigated possible negative effects of climate change and land-use practices on water quality and availability from five springs in the karstic catchments in southern Croatia. The investigated springs are used in the regional public water supply system. Firstly, we employed hydrogeochemical field and laboratory analyses to detect possible traces of anthropogenic activity originating from specific land use. Additionally, we performed hydrological and climate modeling to detect changes in the air temperature, precipitation, and runoff. In particular, we used three regional climate models (Aladin, RegCM3, and Promes). The results estimated an increase in the mean annual air temperature, changes in the precipitation patterns, and reductions in runoff in the study area. Hydrochemical analyses showed standard ion concentrations for karst groundwaters, elevated sulfates due to evaporite deposits in the hinterland, surprisingly low nitrate levels which disproved expected agricultural pollution, and high microbiological activity. Significant water losses are expected in the near future which require immediate attention in order to develop adaptation strategies that focus on sustainable utilization and resilience of freshwater resources. This paper was based on the Interreg Central Europe PROLINE-CE project research in the South Dalmatia. Full article

In this paper, for the first time, a regional-scale 1:100,000 landslide-susceptibility map (LSM) is presented for Sisak-Moslavina County in Croatia. The spatial relationship between landslide occurrence and landslide predictive factors (engineering geological units, relief, roughness, and distance to streams) is assessed using the integration of a statistically based frequency ratio (FR) into the analytical hierarchy process (AHP). Due to the lack of landslide inventory for the county, LiDAR-based inventories are completed for an area of 132 km2. From 1238 landslides, 549 are chosen to calculate the LSM and 689 for its verification. Additionally, landslides digitized from available geological maps and reported via the web portal “Report a landslide” are used for verification. The county is classified into four susceptibility classes, covering 36% with very-high and high and 64% with moderate and low susceptibility zones. The presented approach, using limited LiDAR data and the extrapolation of the correlation results to the entire county, is encouraging for primary regional-level studies, justifying the cost-benefit ratio. Still, the positioning of LiDAR polygons prerequires a basic statistical analysis of predictive factors. Full article

The ability of the ground penetrating radar (GPR) method as a rapid preliminary survey to detect the presence of illegally buried waste is presented in this paper. The test site is located in the countryside of “Sannicandro di Bari” (Southern Italy) and has a surface area of 1500 m2. A total of five parallel profiles were acquired in 2014 using a geophysical survey system instrument (GSSI) equipped with 400 and 200 MHz antennae in the monostatic configuration. Two of the five profiles were registered in a control area to compare a natural condition to a suspected waste buried zone. As a result of a processing and elaboration workflow, GPR investigations allowed us to interpret the signal qualitatively within a maximum depth of about 3 m, identifying many signal anomalies, whose characteristics can be considered typical of buried waste. The GPR response of the three profiles acquired in the suspected area showed substantial differences not found in the control’s profiles. Anomalies related to the presence of intense scattering, of dome structures not attributable to cavities, but rather to a flattening and compacting of different layers, therefore, less electrically conductive, were identified in the suspected area. The interpretation of the results obtained by the GPR profiles was confirmed by excavations carried out with bulldozers. Large quantities of solid waste illegally buried (e.g., waste deriving from construction and demolition activities, bituminous mixtures, discarded tires, glass, plastic, municipal waste) were revealed in all the sites where anomalies and non-conformities appeared compared to the control natural soil.
