“…Upland peats in GB are already experiencing degradation and loss of carbon, but this is mainly due to land use practices, while the pressures of acid pollution are declining (Billett et al 2010, Lindsay & Evans 2010, Smith et al 2010b, Yallop et al 2010. Some areas are probably already experiencing impacts of climate change (Burt & Holden 2010, Coll et al 2010.…”

“…For example, Heinemeyer et al (2010) Smith et al (2010a) can simulate soil carbon stocks across a range of organic soil types (including blanket bog) using minimal data inputs. Smith et al (2010b) used this model to examine changes in soil carbon content due to land-use change in Scotland during 1950-2009. They show that losses from carbon-rich organic soils, were 63 Mt C over this period, greater than the 35 Mt C from mineral soils, and that for carbon-rich soils, 64% of the total soil carbon loss occurred in the last 10 yr. Mitigation options through vegetation management were considered.…”

“…These areas may become more suitable for agriculture as the climate becomes warmer, which would increase pressures from land management, although this has not been assessed in this Special. Excessive burning, overgrazing and drainage can lead to loss of vegetation cover and rapid erosion of peat, sometimes resulting in deep and extensive gully erosion (Billett et al 2010, Evans & Lindsay 2010, Smith et al 2010b, Yallop et al 2010. Climate change may exacerbate erosion where vegetation cover is already reduced e.g.…”

“…Current restoration programmes (including re-vegetation of bare peat) have demonstrated success after only 4 yr (Wilson et al 2010). Restoring carbon rich soils to their original vegetation cover is likely to reduce carbon loss (Smith et al 2010b). Currently one of the most widespread peatland management interventions in the UK is drain or 'grip' blocking (Holden et al 2007); this aims to reverse the drainage process by restoring the water table to natural levels, with positive effects for biodiversity, habitat, water, carbon storage and amenity value.…”

“…In this context, there is currently a challenge reconciling the requirements of GHG emissions inventories and targets for international reporting with the need for a more flexible, responsive tool for policy analysis [66]. Hence, setting targets for woodland expansion as a key pillar of targets for GHG emissions reduction may be ineffective if the woodland targets are met by planting mainly on carbon-rich soils, or potential synergies with agriculture through bioenergy or agroforestry are neglected.…”

Land use patterns are the consequence of dynamic processes that often include important legacy issues. Evaluation of past trends can be used to investigate the role of path dependence in influencing future land use through a reference "business as usual" (BAU) scenario. These issues are explored with regard to objectives for woodland expansion in Scotland as a major pillar of climate change policy. Land use changes based upon recent trends and future transient scenarios to 2050 are used to assess viability of targets for reducing greenhouse gas emissions using analysis based on net emission change factors. The BAU scenario is compared with alternative future scenarios incorporating policy targets and stronger spatial targeting of land use change. Analysis highlights recent trends in new woodland planting on lower quality agricultural land due to socioeconomic and cultural factors. This land is mainly in the wetter uplands and often on carbon-rich soils. Woodland planting following this path dependence can therefore result in net carbon emissions for many years into the future due to soil disturbance during establishment. In contrast, alternative scenarios with more lowland woodland planting have net sequestration potential, with greatest benefits when carbon-rich soils are excluded from afforestation. Spatial targeting can also enhance other co-benefits such as habitat networks and climate change adaptation.

Abstract:We outline the development of a simple, coupled hydrology-biogeochemistry model for simulating stream discharge and dissolved organic carbon (DOC) dynamics in data sparse, permafrost-influenced catchments with large stores of soil organic carbon. The model incorporates the influence of active layer dynamics and slope aspect on hydrological flowpaths and resulting DOC mobilization. Calibration and evaluation of the model was undertaken using observations from Granger Basin within the Wolf Creek research basin, Yukon, northern Canada. Results show that the model was able to capture the dominant hydrological response and DOC dynamics of the catchment reasonably well. Simulated DOC was highly correlated with observed DOC (r 2 = 0.65) for the study period. During the snowmelt period, the model adequately captured the observed dynamics, with simulations generally reflecting the timing and magnitude of the observed DOC and stream discharge. The model was less successful over the later summer period although this partly reflected a lack of DOC observations for calibration. The developed model offers a valuable framework for investigating the interactions between hydrological and DOC processes in these highly dynamic systems, where data acquisition is often very difficult.
