The task facing scientists and technologists is both to provide robust tools for predicting and planning for regional and local shortages, and to ensure that these tools are appropriate for the situations in which they must be used.
A background article summarises the key issues, including the different ways in which climate change is expected to affect water security, and describes the water management strategies — both technical and social — available to mitigate them.
A major obstacle to implementing such strategies in local communities of the developing world, according to climate scientist Mark New from University of Oxford, is the uncertaintywith which we can predict changes at the regional or local level. The solution, he suggests, lies in ensuring that there is sufficient flexibility and adequate in-built options in water management projects to cope with major variations in water supply. water supply.
