Climate change is a major issue for all levels of government, global, national and local. Local authorities' responses to climate change have tended to concentrate on their role in reducing greenhouse gases. However, the scientific consensus is that we also need to adapt to unavoidable climate change. Spatial planning at a local level has a critical anticipatory role to play in promoting robust adaptation. This paper reviews the shift in local authorities' planning policies for climate change adaptation in the UK since 2000, and provides evidence of underlying attitudes amongst planning professionals to climate change. It shows that, while the issue of climate change is becoming recognized with respect to flood risk, the wider implications (for instance, for biodiversity and water resources) are not yet integrated into plans. The reasons for this lie in lack of political support and lack of engagement of the planning profession with climate change networks. But the paper also argues there are difficulties in acknowledging the need for adaptation at the local level, with the short-term horizons of local plans at odds with perceptions of the long-term implications of climate change.

A meta-modelling approach has been adopted to link simulations of low and high water flows with simulations of suitable climate space for a selection of fen and bog species with differing drought and flood tolerance. The linked meta-models were used to examine the impacts of socio-economic and climate change scenarios on wetlands in two contrasting regions of the UK. The hydrological model shows that low and high flows are sensitive to climate change and to the regional distribution of abstractions and discharges. Where there are large changes in urbanisation, flows are more sensitive to socio-economic change. The changes in high flows have little impact on the species selected, but changes in low flows result in a number of areas becoming marginal or unsuitable due to dryness. At the regional scale, adaptation options appear to be limited and mostly involve, for surface water-influenced wetlands, increased water imports (either directly through increased non-consumptive water demand or indirectly through river augmentation), which may not be consistent with the socio-economic scenario or be feasible. This paper shows, therefore, that changes in hydrological regime are important for the future of wetlands and that these may depend as much on the future socio-economic situation as the projected changes in climate.
