Society, in its future planning, must take account of the climate change which is already taking place and of the uncertainty associated with different scenarios for what the future climate may be. This study illustrates the methods which are in use today, or which are available, when local authorities make plans for water resources and pursue their work on related environmental objectives. We have also made an assessment of whether the methods can be regarded as suitable for dealing with the uncertainty which surrounds future climatic conditions. The study shows that various forms of mapping, rules of thumb, and models are the main methods used by local authorities in their water resource planning exemplified by their plans for local water and sewage facilities. None of the methods in use can be regarded as being suitable for dealing with future uncertainties, but at the same time we can say that there are other model tools which the local authorities should be able to use. However, the availability of measurement data, particularly on a local scale, could prove to be a limitation. We can also say that current planning already contains a certain degree of uncertainty, the extent of which is unclear, which is likely to affect the possibilities for handling future uncertainties.
