Descriptif
The thesis contributes to the exploration of new and innovative methodologies
by supporting the adaptation process to climate change and disaster risk prevention
in least developed countries through the assessment of multi-hazard risk under
future climate scenarios. The thesis takes its cue from two papers published during
the three years of doctorate which are : i) Multihazard risk assessment for planning
with climate in the Dosso Region, Niger, by Tiepolo, Maurizio ; Bacci, Maurizio ;
Braccio, Sarah [1], and ii) Multi-Hazard Risk Assessment at Community Level
Integrating Local and Scientific Knowledge in the Hodh Chargui, Mauritania, by
Tiepolo, Maurizio ; Bacci, Maurizio ; Braccio, Sarah ; Bechis, Stefano [2]. Both
papers deal with the current multi-hazard risk assessment, at a regional scale basis,
in these two territories. A part of the chapters 3.1, 3.2, 3.6, 4.1, 4.2, 4.6 and 5 are
wrote considering the previous and cited papers.3
This thesis gathers, with a holistic and interdisciplinary approach, a review of
concepts of multi-hazard risk assessment and notions about climate modeling and
downscaling techniques, then, starting from the two above mentioned papers,
produce the bias-corrected climatic projections datasets and develop the future
multi-hazard risk assessment for the two case studies. The future scenarios are
compared with the current assessment thus intercepting the most significant trends
in risk evolution. The study follows on with a discussion on the obtained results.
The last chapter draws conclusions on the sustainability and replicability of the
method in similar contexts and its ability to support the medium-long term planning
process through the identification of intervention priorities.
The investigated case studies are :
• Hodh El Chargui Region, Mauritania
• Dosso Region, Niger
