摘要

Climate change is a complex phenomenon with diverse impacts across the world. Climate change impacts are also perceived differently across people of any given community. In this study, we interviewed 166 Tuareg people in five villages in the Tassili N’Ajjer region (Algeria, Sahara Desert) to explore how perceptions of climate change impacts vary across age, gender, education, place of origin, living conditions, and use of communication technology. Quantitative information on perceptions of impacts was gathered using a standardised protocol and analysed using an agglomerative hierarchical classification on principal components issued from a multiple correspondence analysis. Meteorological data shows a trend of decreased precipitations and increased temperatures. While most people report a decrease in precipitation and increase in temperature, not all of them do so. Our data reveals three different profiles of perceptions of change. Both age and the degree of use of communication technology significantly influence perceptions of climate change impacts, with differences persisting between members of the same household. This has important implications for the successful implementation of adaptation and mitigation strategies among rural communities of hyper-vulnerable areas.
