Since the 1970s, Niger basin has been characterized by hydro-climatic changes which have significant impacts on local populations. These are not well documented as a result of decreasing observation network for data. Indigenous peoples' knowledge increasingly considered an important component in addressing these data gaps. We evaluated consistency indigenous perceptions and adaptive responses with rainfall river discharge observations basin. Socioeconomic were collected from 239 households...

Forests, wetlands, water bodies decreased between...
This study analyzed trends in extreme precipitation based on daily rainfall data provided by Bénin Méteo Agency for the Upper Ouémé valley Benin over period 1951–2014. Eleven indices divided into two groups were considered. The first group consists of frequency indices: number heavy days, very days and extremely days; maximum Consecutive dry wet days. second concerns intensity: (RX1day), five-day (RX5day), annual total wet-day (PRCPTOT), simple intensity index (SDII), day (R95P) (R99P)....
