【 摘 要 】

ABSTRACT: This paper provides a case study from the northern Senegal wetlands documenting trends in inter-annual and seasonal climate variability during the past century as well as human vulnerability and adaptation to anomalous climate events. A seculardecline in precipitation during the past 3 decades has resulted in the construction of 2 dams on the Senegal River in the 1980s and an interstate river basin development strategy to develop hydroelectricity, irrigation farming, and a navigable waterway.Current agro-ecological production systems dependent on a seasonal riparian flood cycle could be curtailed in trying to meet these development objectives. Two hydrological time flow series illustrating the importance of inter-annual and seasonal climatevariability for the region are used to weigh the costs and benefits of competing water use scenarios for end users.
