Flood dynamics, social vulnerability and risk perception: challenges for flood risk management
Full text linkThe 2015 was a remarkable year in the global policy with the publication of three milestones: The Sendai Framework for Disaster Risk Reduction, the Sustainable Development Goals and the Paris Agreement for Climate Change. The global significance of such documents raised interest in the understanding of the interaction between humans, the Earth and the climate, and the past and current development of disasters. Anthropogenic landscapes are one of the most sensitive environments to hydrological extremes, fluctuations and changes. Here, hydrogeological disasters such as floods are considered one of the major threat of our time, bringing negative consequences to the whole societal system. However, while climate change and socio-economic development are important drivers of flood impacts, human behaviours can alter the potential effects of a flood by undertaking protective behaviours. In this regard, risk perceptions are potential drivers of behaviour. Thus, exploring individuals’ concern about natural hazards provide essential information about people willingness to take precautionary measures and can, therefore, identify the major reasons behind the unsatisfactory performance level of current disaster management practices. This suggests that advancing our understanding of the hazard perceptions by investigating personal, social and cultural influences can help in determining people preparedness. Limitations of personal action in front of the risk might come from social vulnerabilities, those factors that increase the fragility of individuals toward a particular threat. In light of this, there is the need to create people-oriented management strategies, with governments focused on vulnerable groups, able to recognise local capacities, foster communication and create awareness campaigns to empower the citizens and mitigate the undesirable effects of such events.
For this reason, this thesis proposes an analysis of flood and human interactions using historical and land use change data, participatory approaches and analysis of social vulnerability. Furthermore, this thesis would suggest possible flood risk management actions and policies in different anthropogenic communities. Different study areas have been chosen in order to tackle site-specific flood dynamics and capture how the socio-political and unique cultural background of each community might affect individuals conceptualisation of risk

Full text linkRaising interest in the interaction between humans and climate drivers to understand the past and
current development of floods in urbanised landscapes is of great importance. This study presents a
regional screening of land-use, rainfall regime and flood dynamics in north-eastern Italy, covering the
timeframe 1900–2010. This analysis suggests that, statistically, both climate and land-use have been
contributing to a significant increase of the contribution of short duration floods to the increase in the
number of flooded locations. The analysis also suggests that interaction arises, determining land-use
dynamics to couple with climatic changes influencing the flood aggressiveness simultaneously. Given
that it is not possible to control the climatic trend, an effective disaster management clearly needs an
integrated approach to land planning and supervision. This research shows that land management and
planning should include the investigation of the location of the past and future social and economic
drivers for development, as well as past and current climatic trends
