In Shanghai, the problem with climate change will not be too little water, but too much. Shanghai is already one of the world's most flood prone cities, and with rising water levels due to melting polar ice, as well as increased typhoon activity due to atmospheric and ocean warming, it's only going to get worse. Shanghai is more fortunate than many other cities in its situation as it is able to afford to build coastal defences (they've built over 500km of flood walls in recent years) and institute other anti-flooding measures that other poorer coastal cities (example Dhaka, Bangladesh) cannot afford.
