The long-term impacts of climate change on water resources are expected to be considerable in many parts of the globe. Resulting hydrologic changes can have a high impact on river basins like Krishna, India and Murray Darling, Australia where severe competition of water between stakeholders and states exists. Australia is already experiencing significant impacts of climate change: the average surface air temperatures have increased by 0.9°C since 1950 and precipitation has declined along the east and west coasts of the country. Analysis of emission scenarios suggests that warming of between 1°C and 2.5°C is likely by 2070 if emissions are low and between 2°C and 5°C under a high emission scenario. In India climate change possess challenges due to its vast geographic diversity.
