This collection of reports looks at how ICTs can be used to help communities in developing countries facing water stress adapt to climate change. The role and potential of ICTs in helping communities employ innovative approaches to prepare for, respond and adapt to climate change are increasingly being recognised. Within the water sector, ICTs can contribute towards improvements in water resource management techniques; strengthen the voice of the most vulnerable within water governance processes; create greater accountability; provide access to locally relevant information needed to reduce risk and vulnerability; and improve networking and knowledge sharing to disseminate good practices and foster multi-stakeholder partnerships, among others. While drawing on current experiences in the field of water management and sustainability, the perspective of the authors is primarily from the ICT for development (ICT4D) sector. Because of this the reports should be considered exploratory, offering a fresh perspective to the field of water security in vulnerable contexts.
