“…Our results agree with other studies that examine changes in soil C stocks as they respond to climate change, despite some potential methodological limitations (Meersmans et al, 2016; Wiesmeier et al, 2016). While our study focused on topsoil C stocks, recent evidence suggests that potential C losses in topsoil may be somewhat offset by gains in deeper soil layers (Muñoz‐Rojas et al, 2017).…”

Dryland agroecosystems could be a sizable sink for atmospheric carbon (C) due to their spatial extent and level of degradation, providing climate change mitigation. We examined productivity and soil C dynamics under two climate change scenarios (moderate warming, representative concentration pathway [RCP] 4.5; and high warming, RCP 8.5), using long-term experimental data and the DayCent process-based model for three sites with varying climates and soil conditions in the US High Plains. Each site included a no-till cropping intensity gradient introduced in 1985, with treatments ranging from wheat-fallow (Triticum aestivum L.) to continuous annual cropping and perennial grass. Simulations were extended to 2100 using data from 16 global circulation models to estimate uncertainty. Simulated yields declined for all crops (up to 50% for wheat), with small changes after 2050 under RCP 4.5 and continued losses to 2100 under RCP 8.5. Of the cropped systems, continuous cropping had the highest average productivity and soil C sequestration rates (78

“…There is great concern about the magnitude of this feedback on soils of the northern latitudes (24), but the same physical impacts will be felt by farmland soils. Soilclimate feedback will reduce the magnitude of the maximum sequestration potential of all soils by an uncertain amount (25).…”

“…Climate change and soil degradation are among the major threats to agriculture and food security (Lal et al, ; Meersmans et al, ; Tilman et al, ) and recognized as such by farmers across Europe (Olesen et al, ). Following the Paris climate agreement, 193 nations have committed to keep the global average warming well below 2°C relative to preindustrial temperatures and pursue efforts to limit the temperature increase to 1.5°C.…”

Impacts and Uncertainties of +2°C of Climate Change and Soil Degradation on European Crop Calorie Supply

Even if global warming is kept below +2°C, European agriculture will be significantly impacted. Soil degradation may amplify these impacts substantially and thus hamper crop production further. We quantify biophysical consequences and bracket uncertainty of +2°C warming on calories supply from 10 major crops and vulnerability to soil degradation in Europe using crop modeling. The Environmental Policy Integrated Climate (EPIC) model together with regional climate projections from the European branch of the Coordinated Regional Downscaling Experiment (EURO‐CORDEX) was used for this purpose. A robustly positive calorie yield change was estimated for the EU Member States except for some regions in Southern and South‐Eastern Europe. The mean impacts range from +30 Gcal ha−1 in the north, through +25 and +20 Gcal ha−1 in Western and Eastern Europe, respectively, to +10 Gcal ha−1 in the south if soil degradation and heat impacts are not accounted for. Elevated CO2 and increased temperature are the dominant drivers of the simulated yield changes in high‐input agricultural systems. The growth stimulus due to elevated CO2 may offset potentially negative yield impacts of temperature increase by +2°C in most of Europe. Soil degradation causes a calorie vulnerability ranging from 0 to 50 Gcal ha−1 due to insufficient compensation for nutrient depletion and this might undermine climate benefits in many regions, if not prevented by adaptation measures, especially in Eastern and North‐Eastern Europe. Uncertainties due to future potentials for crop intensification are about 2–50 times higher than climate change impacts.
