ConclusionsConclusions There are many interactions between There are many interactions between
reservoirs and various water sub-sectorsreservoirs and various water sub-sectors Some potential impact of climate change was Some potential impact of climate change was
considered using two extreme scenarios: drier considered using two extreme scenarios: drier and wetterand wetter
Due to the large variety of interactions it is not Due to the large variety of interactions it is not possible to identify which scenario leads to possible to identify which scenario leads to more positive or negative impacts and more positive or negative impacts and mitigation of one effect might lead to worsening mitigation of one effect might lead to worsening of another of another
