Soil Water Assessment Tool (SWAT) simulated hydrological impacts of land use change from temperate grassland to energy crops:A case study in western UK

When considering the large‐scale deployment of bioenergy crops, it is important to understand the implication for ecosystem hydrological processes and the influences of crop type and location. Based on the potential for future land use change (LUC), the 10,280 km2 West Wales Water Framework Directive River Basin District (UK) was selected as a typical grassland dominated district, and the Soil & Water Assessment Tool (SWAT) hydrology model with a geographic information systems interface was used to investigate implications for different bioenergy deployment scenarios. The study area was delineated into 855 sub‐basins and 7,108 hydrological response units based on rivers, soil type, land use, and slope. Changes in hydrological components for two bioenergy crops (Miscanthus and short rotation coppice, SRC) planted on 50% (2,192 km2) or 25% (1,096 km2) of existing improved pasture are quantified. Across the study area as a whole, only surface run‐off with SRC planted at the 50% level was significantly impacted, where it was reduced by up to 23% (during April). However, results varied spatially and a comparison of annual means for each sub‐basin and scenario revealed surface run‐off was significantly decreased and baseflow significantly increased (by a maximum of 40%) with both Miscanthus and SRC. Evapotranspiration was significantly increased with SRC (at both planting levels) and water yield was significantly reduced with SRC (at the 50% level) by up to 5%. Effects on streamflow were limited, varying between −5% and +5% change (compared to baseline) in the majority of sub‐basins. The results suggest that for mesic temperate grasslands, adverse effects from the drying of soil and alterations to streamflow may not arise, and with surface run‐off reduced and baseflow increased, there could, depending on crop location, be potential benefits for flood and erosion mitigation

The political sustainability of climate policy: the case of the UK Climate Change Act

This paper assesses the forces working for and against the political sustainability of the UK 2008 Climate Change Act. The adoption of the Act is seen as a landmark commitment to action on climate change, but its implementation has not been studied in any depth. Recent events, including disagreements over the fourth carbon budget and the decarbonisation of the electricity sector, shows that while the Act might appear to lock in a commitment to reducing emissions through legal means, this does not guarantee political lock-in. The assumption, made by some proponents of the Act, that accountability of political leaders to a public concerned about climate change, via Parliament, would provide the main political underpinning to the Act is criticised. An analysis of alternative sources of political durability is presented, drawing on a framework for understanding the sustainability of reform developed by Patashnik. It is argued that the Act has helped create major institutional transformations, although the degree to which new institutions have displaced the power of existing ones is limited. The Act has produced some policy feedback effects, especially in the business community, and some limited investment effects, but both have been insufficient to withstand destabilisation by recent party political conflicts. The Climate Change Act remains at risk

Dataset for "A simplified model for minor and major loop magnetic hysteresis and its application for inference of temperature in induction heated particle beds"

The dataset contains the background data for recreation or use of the results presented in Figures 2 - 7. The data supports the recent publication that demonstrated how a LangArc model can successfully fit both major and minor hysteresis loops of a bed of magnetic particles in real time using instruments that detect changes in the magnetic field strength, such as in-situ pick-up coils. The data is intelligible when cross-referenced to the respective Figure, its caption and experimental details published in the article. The data presents a full numerical representation of the results published in the article including the direct experimental data and the model fit results for the various cases. The data will support other researchers in developing their own models to fit the results of magnetic hysteresis experiments

Examples and instructions are included within the spreadsheet. The spreadsheet is intended to be a tool for LCA practitioners to quickly assess whether temporal aspects of GHG results are relevant and should be reported upon
