Cette épreuve consistera en la défense publique d’une dissertation intitulée :

« Population vulnerability to drought and other extreme weather events in the context of climate change - a case study in the Central Highland of Vietnam ».

Abstract

This dissertation is about the population vulnerability to drought and other extreme weather events in the context of climate change – a case study in the Central Highlands of Vietnam. The findings of this study indicated that access to water (sensitivity) and livelihood strategies (adaptive capacity) are two major causes of high vulnerability to drought for all districts and surveyed communities.  The study also found that there is a significant difference in climate change perceptions and observations of climate change-related extreme events, depending on different socio-economic and demographic household characteristics: in particular, education, preferred media sources and income sources have significant effects on local people’s perceptions regarding drought. Besides, this study is the first to develop and assess a coffee yield forecasting method at the regional scale for Dak Lak province, in the Central Highlands of Vietnam, by using the Crop Growth Monitoring System Statistical Tool (CGMSstatTool – CST) software and vegetation biophysical variables (NDVI, LAI, and FAPAR) derived from satellite remote sensing data (SPOT-VEGETATION and PROBA-V). These results might help assess the needs in terms of actions and designing site-specific intervention strategies to reduce the vulnerability of agriculture smallholders to climate change.
