Abstract
Drought is a complex phenomenon, which involves natural factors such as meteorology, hydrology, agriculture, landform, geology, and is also closely related to human conditions, like society, economy and culture. At present, there are many studies on the diagnosis, transmission, causes and influences of drought events, but there are some deficiencies in the review of historical drought events under a comparative analysis of different regions. Taking the Yangtze River Basin in China and Sao Francisco Basin in Brazil as objects, we analyze how ca we learn from historical evidences in regional differences of the spatio-temporal evolution of drought events, the driving forces of drought formation, the influence of climate change, and the disaster risk reduction strategies for the two basins. Despite of different monitoring periods, we elucidate similarities and differences in the historical solutions for droughts in the two basins. Thus, we address how history can help on adaptation strategies to learn from extreme droughts and provide more robust decision support schemes.
