The authors consider expected change within the context of recently observed climate variability in the basins to better understand the potential impact of expected change and the options available for adaptation. They use multi-global circulation model climate projections for the AR4 SRES A2a scenario, downscaled and extracted for each basin. They find significant differences in the impacts (both positive and negative impacts) of climate change, between and within basins, but also find large-scale uncertainty between climate models in the impact that is projected. specialized water resources water use mega-basins climate spatial analysis 062 36 1 96-124 2011 0250-8060 https://www.documentation.ird.fr/hor/PAR00006810 10.1080/02508060.2011.543408 0250-8060 [F B010053403] https://www.documentation.ird.fr/hor/PAR00006810 https://www.documentation.ird.fr/intranet/publi/2011/03/010053403.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2011-04-07 2017-08-23 PAR00006810 fre
