20. FutureWater Conclusions  Three adaptations Business as usual (Impacts) Business as usual (Impacts) Food Food Environment Environment  Adaptation strategies: Can have negative impact on other sectors Can have negative impact on other sectors  Models as tool for scenario analysis Basin Basin Field Field  Means are less important than extremes  Overall Climate Change positive for Walawe
