2. ‘A glorious time?’ Some reflections on flooding in the Somerset Levels

Author

McEwen, L, Jones, O, and Robertson, I

Abstract

Severe floods on the Somerset Levels in winter 2014, and a series of other recent extreme floods across the UK, pose questions about the research needed to unravel the complex nature of flood risk and its implications for society. While much emphasis is placed on research in the natural and engineering sciences to better predict flood risk and develop solutions, this paper discusses what social science, and arts and humanities approaches can contribute to this challenging issue, alongside, and importantly integrated with, the natural sciences. Drawing upon a series of interconnected social science and arts and humanities research projects, in this paper we explore how different knowledges might contribute in dialogue around flood risk; water, senses of place and community in resilience building; the power dynamics in narratives about water; and the value of conceptualising flood heritage ‘from below’ in bringing community voices to the table. We argue that social science, and arts and humanities approaches are needed to explore creative solutions to changing or challenging flood risk. In interdisciplinary configurations in particular, they can generate much needed, creative, transformative narratives which can play key roles in the interplay and negotiation between science, policy and public understanding.

Abstract

The increasing carbon dioxide (CO2) concentration in the atmosphere in combination with climatic changes throughout the last century are likely to have had a profound effect on the physiology of trees: altering the carbon and water fluxes passing through the stomatal pores. However, the magnitude and spatial patterns of such changes in natural forests remain highly uncertain. Here, stable carbon isotope ratios from a network of 35 tree-ring sites located across Europe are investigated to determine the intrinsic water-use efficiency (iWUE), the ratio of photosynthesis to stomatal conductance from 1901–2000. The results were compared with simulations of a dynamic vegetation model (LPX-Bern 1.0) that integrates numerous ecosystem and land–atmosphere exchange processes in a theoretical framework. The spatial pattern of tree-ring derived iWUE of the investigated coniferous and deciduous species and the model results agreed significantly with a clear south-to-north gradient, as well as a general increase in iWUE over the 20th century. The magnitude of the iWUE increase was not spatially uniform, with the strongest increase observed and modelled for temperate forests in Central Europe, a region where summer soil-water availability decreased over the last century. We were able to demonstrate that the combined effects of increasing CO2 and climate change leading to soil drying have resulted in an accelerated increase of iWUE. These findings will help to reduce uncertainties in the land surface schemes of global climate models, where vegetation–climate feedbacks are currently still poorly constrained by observational data.
