Facing natural disasters through the endorsement of authoritarian attitudes
2020
Abstract We analyzed the relations between exposure to news describing a natural disaster and right-wing authoritarianism (RWA) with 241 Italian adults, surveyed twice, before and after a severe earthquake. Our results were compatible with the idea that the exposure to earthquake news led to an increase in RWA among people who had low, but not among who had relatively high, authoritarian levels before the event. We discuss the findings in terms of compensatory control, and highlight strengths and limitations of the study.
Etna and the perception of volcanic risk
2013
Sicily’s uneven geological structure is positioned within a system of tectonic plates, and its very active volcano has always made it prone to disasters. Many Sicilian cities have in fact been destroyed by natural events many times over the centuries. This can certainly be understood negatively as the destruction of entire towns, the emission of volcanic ash, and the mutation of landscapes by a terrifying force have instilled fearful memories in local populations. But from another point of view one must consider the positive elements of Etna. Its beautiful landscapes were a major attraction on the Grand Tour, and its inhabitants have long associated the volcano with the concept of rebirth a…
Application of the group method of data handling (GMDH) approach for landslide susceptibility zonation using readily available spatial covariates
2022
Abstract Landslide susceptibility (LS) mapping is an essential tool for landslide risk assessment. This study aimed to provide a new approach with better performance for landslide mapping and adopting readily available variables. In addition, it investigates the capability of a state-of-the-art model developed using the group method of data handling (GMDH) to spatially model LS. Furthermore, hybridized models of GMDH were developed using different metaheuristic algorithms. The study area was the Bonghwa region of South Korea, for which an accurate landslide inventory dataset is available. We considered a total of 13 spatial covariates (altitude, slope, aspect, topographic wetness index, val…
Climate and agriculture: empirical evidence for countries and agroecological zones of the Sahel
2022
International audience; ow heterogenous is the impact of climate change across space and the type of agricultural production? In this paper, we investigate the relationship between climate change and variability, measured by temperature and rainfall, and agricultural production at the country and agroecological zone levels of the Sahel. We consider a crop production index and five cereals (maize, millet, sorghum, wheat and rice). Based on an original climate database and an agricultural production function estimated for the period 1961–2016, we show that average rainfall and temperature during the growing season indeed have highly heterogeneous effects on agricultural production, depending …
GAMS files for the multi-objective models to locate temporary distribution centers after sudden-onset disasters
2019
These are the GAMS file with some a sample dataset that model locating temporary distribution centers after sudden-onset disasters. Required input data should be changed in the front.
