Information and communications technologies (ICTs) have proven useful in tailoring responses to situations arising out of the climate-water nexus. ICTs have emerged as a strong way to understand water security challenges. They are increasingly being adopted as key decision support mechanisms for adapting to climate change effects in the developing world. However, ICTs must not be considered simply a panacea for water security. Rather, they are tools that can be smartly used in developing appropriate responses to problems in the water climate change arena. The focus of this reports compilation is how information and communications technologies (ICTs) can be used to help communities in developing countries facing water stress adapt to climate change.
