The latest report from the U.N. Intergovernmental Panel on Climate Change (IPCC) predicts a rise in global temperature of between 0.3 and 4.8 degrees Celsius (0.5 to 8.6 Fahrenheit) by the late 21st century.
Countries such as India are likely to be hit hard by global warming, which will bring more freak weather such as droughts that will lead to serious water shortages and affect agricultural output and food security.
"Unfortunately, the world has not really woken up to the reality of what we are going to face in terms of the crises as far as water is concerned," IPCC Chair Rajendra Pachauri told participants at a conference on water security.
"If you look at agricultural products, if you look at animal protein - the demand for which is growing - that's highly water intensive. At the same time, on the supply side, there are going to be several constraints. Firstly, because there are going to be profound changes in the water cycle due to climate change."
Development experts around the world have become increasingly concerned about water security in recent years.
More frequent floods and droughts caused by climate change, pollution of rivers and lakes, urbanization, over-extraction of ground water and expanding populations mean that many nations such as India face serious water shortages.
In addition, the demand for more power by countries like India to fuel their economic growth has resulted in a need to harness more water for hydropower dams and nuclear plants.

Pachauri said it was necessary to bring in technology to help harness water more efficiently, particularly in agriculture where there is a lot of wastage.
"Naturally, this (water crisis) is also going to lead to tensions - probably some conflict between riparian groups and riparian states," he said.
