An Interdisciplinary Approach to the Sustainable Management of Territorial Resources in Hodh el Chargui, Mauritania

Sustainability (2020)

Chiara Caselle Sabrina Maria Rita Bonetto Domenico Antonio De Luca Manuela Lasagna Luigi Perotti

The present study proposes an analytical investigation of the natural resources and social framework of the Hodh el Chargui region (Mauritania), aiming to offer a useful instrument for planning and management to the local authorities. The situation of the region was evaluated by means of a participatory survey carried out among the local inhabitants. The obtained results include a collection of data about population, territorial organization, access to basic education and health services, infrastructure, main economic activities, and natural resources (in terms of water, both surface and groundwater, duration and intensity of rainfalls, soil types, and vegetal resources). The survey outcomes were completed with an integrated approach based on Earth Observation (EO) data supports, such as digital elevation models (DEMs) and Landsat8 imagery. The interdependence among the different data was evaluated and discussed, with regard to the influence of the availability of natural resources on the development of agricultural activities and on the general social welfare. The results are organized in the form of digital maps and a user-friendly webmap platform to facilitate access for all the technical and nontechnical actors involved in the project.

Debris flow susceptibility mapping using the Rock Engineering System (RES) method: a case study

Landslides (2022)

Davide Vianello Federico Vagnon Sabrina Maria Rita Bonetto Pietro Mosca

Abstract The main purpose of the present study is to develop a debris flow susceptibility map of a mountain area (Susa Valley, Western Italian Alps) by using an upgraded version of the Bonetto et al. ( Journal of Mountain Science 18, 2021) approach based on the Rock Engineering System (RES) method. In particular, the area under investigation was discretized in a 5 × 5-m grid on which GIS-based analyses were performed. Starting from available databases, several geological, geo-structural, morphological and hydrographical predisposing parameters were identified and codified into two interaction matrices (one for outcropping lithologies and one for Quaternary deposits), to evaluate their mutual interactions and their weight in the susceptibility estimation. The result for each grid point is the debris flow propensity index (DfPI), an index that estimates the susceptibility of the cell to be a potential debris flow source. The debris flow susceptibility map obtained was compared with those obtained from two expedited and universally recognized susceptibility methods, i.e. the Regional Qualitative Heuristic Susceptibility Mapping (RQHSM) and the Likelihood Ratio (LR). Each map was validated by using the Prediction Rate Curve method. The limitations and strong points of the approaches analysed are discussed, with a focus on the innovativeness and uniqueness of the RES. In fact, in the study site, the RES method was the most efficient for the detection of potential source areas. These results prove its robustness, cost-effectiveness and speed of application in the identification and mapping of sectors capable of triggering debris flow.

The contribution of remotely sensed data to the stress state evaluation in underground marble quarries

The Egyptian Journal of Remote Sensing and Space Science (2021)

Sabrina Maria Rita Bonetto Federico Vagnon Gessica Umili Davide Vianello M. Migliazza

An in-depth knowledge of the geostructural characteristics of the territory is fundamental for optimizing the design of artificial structures. Feasibility, costs, duration, and issues of the works are strictly correlated with the geological, geomechanical, and in situ stress features of the area. Remotely sensed data represent a source of information for detecting tectonic structures that can be complementary to traditional surveys, with the advantage of being cheaper, of covering large areas and of reducing time for surveying. The study of the regional tectonic setting together with local structural features is fundamental to define the far-field tectonic stress and for correctly modeling the induced stress during excavation activities and monitoring stress variations. A multiscale and multidisciplinary approach was set up and applied to an area in the Alpi Apuane marble district (Tuscany, Italy). Visually and semi-automatically detected geological structures were analyzed and correlated to data from in-situ measurements in four underground marble quarries, to define the far-field stress state. This study is also an attempt to bridge the gap between structural geology analysis and remotely sensed data for far-field stress definition, correlating on-field kinematic observations and in situ stress measurements.

Subsidence hazards connected to quarrying activities in a karst area: the case of the Moncalvo sinkhole event (Piedmont, NW Italy)

Proceedings of the Estonian Academy of Sciences Geology (2008)

Sabrina Maria Rita Bonetto Adriano Fiorucci Mauro Fornaro Bartolomeo Vigna

Gypsum is an important raw material for constructions and other industrial sectors.In Piedmont (NW Italy), main gypsum bodies are located in the Monferrato area, where large open pits and underground quarries are present.The gypsumbearing formation outcropping in this area shows typical geological, structural, and hydrogeological features, which affect the quarrying and the related interaction with natural phenomena, human activities, and land use.In particular, gypsum karst has considerable influence on mining operations, as well as mining operations can produce strong impact on gypsum karst.In Monferrato, a specific case of interaction between the quarrying activity and geological, hydrogeological, and territorial setting is represented by the event of water inrush that happened in the Moncalvo underground quarry in association with the development of a surface sinkhole phenomenon.

Groundwater Resources Assessment for Sustainable Development in South Sudan

Sustainability (2020)

Manuela Lasagna Sabrina Maria Rita Bonetto Laura Debernardi Domenico Antonio De Luca Carlo Semita

The economic activities of South Sudan (East-Central Africa) are predominantly agricultural. However, food insecurity due to low agricultural production, connected with weather conditions and lack of water infrastructure and knowledge, is a huge problem. This study reports the results of a qualitative and quantitative investigation of underground and surface water in the area of Gumbo (east of Juba town) that aims to assure sustainable water management, reducing diseases and mortality and guaranteeing access to irrigation and drinking water. The results of the study demonstrate the peculiarity of surface and groundwater and the critical aspects to take into account for the water use, particularly due to the exceeding of limits suggested by the WHO and national regulation. The outcomes provide a contribution to the scientific overview on lithostratigraphic, hydrochemical and hydrogeological setting of a less-studied area, characterized by sociopolitical instability and water scarcity. This represents a first step for the improvement of water knowledge and management, for sustainable economic development and for social progress in this African region.

Geophysical surveys for non‐invasive characterization of sinkhole phenomena: A case study of Murisengo

Earth Surface Processes and Landforms (2023)

Sabrina Maria Rita Bonetto Chiara Caselle Cesare Comina Federico Vagnon

Abstract The present research investigates the morphology and genetical mechanism of a sinkhole which occurred in 2019 in Murisengo (NW Italy). This landform is representative of several subsidence phenomena that often concern the Monferrato area (NW Italy). In concomitance with the appearance of the sinkhole at the surface, a cone of detrital material was found in the drifts of a nearby underground quarry. A geological survey was performed in the underground quarry in order to understand the interaction between the geological and geostructural features of the rock body and the generation of the sinkhole. Moreover, the underground sinkhole morphology was investigated through electrical resistivity tomography (ERT) surveys performed at the surface. The ERT outputs were combined to obtain a 3D image of the phenomenon and the 3D reconstruction was then compared with the geomorphological and structural setting of the area. Results suggest that a viscoplastic flow of clay‐rich sediments within a conduit in the gypsum bedrock (suffusion process) generated the sinkhole.

Groundwater Resources in the Main Ethiopian Rift Valley: An Overview for a Sustainable Development

Sustainability (2021)

Sabrina Maria Rita Bonetto Chiara Caselle Domenico Antonio De Luca Manuela Lasagna

In arid and semi-arid areas, human health and economic development depend on water availability, which can be greatly compromised by droughts. In some cases, the presence of natural contaminants may additionally reduce the availability of good quality water. This research analyzed the water resources and hydrochemical characteristics in a rural area of the central Main Ethiopian Rift Valley, particularly in the districts of Shashemene, Arsi Negelle, and Siraro. The study was developed using a census of the main water points (springs and wells) in the area and the sampling and physico-chemical analysis of the water, with particular regard to the fluoride concentration. In many cases, fluoride content exceeded the drinking water limits set by the World Health Organization, even in the absence of anthropogenic contamination. Two different aquifers were recognized: A shallow aquifer related to the eastern escarpment and highlands, and a deep aquifer in the lowland areas of the rift valley on the basis of compositional changes from Ca–Mg/HCO3 to Na–HCO3. The distribution of fluoride, as well as pH and EC values, showed a decrease from the center of the lowlands to the eastern highlands, with similar values closely aligned along an NNE/SSW trend. All these data contribute to creating awareness among and sharing information on the risks with rural communities and local governments to support the adequate use of the available water resources and to plan appropriate interventions to increase access to fresh water, aimed at the sustainable human and rural local development of the region.
