“…This is contrary to the yield pattern found in the new and old genotype analyzed in the present study. The observation that crop cultivars respond differently to climate change scenarios has been documented by others from studies with barley, oat and oilseed rape (Fangmeier et al 2000;Chauhan et al 2005;Johannessen et al 2002Johannessen et al , 2005Clausen et al 2011), and gives hope to that selection of specific cultivars with tolerance to abiotic stressors may help safeguarding the future primary production.…”

“…Simulation modelling suggests that potato should have a positive tuber yield response to elevated CO 2 . Fangmeier et al (2000) found that elevated CO 2 caused an elevated grain yield in barley as did Soebø and Mortensen (1996). In agricultural systems, the balance of crop type and competing weeds, and relative ability to utilise increased carbon dioxide in the atmosphere will have a significant impact on specific production systems.…”

Possible change in Irish climate and its impact on barley and potato yields

Climate change scenarios can be used with crop simulation models to predict the impact of climate change on agricultural production. Focusing on two specific arable crops: (i) barley, a currently successful cereal crop, well adapted to the Irish climate and a staple of the tillage production sector; and (ii) potato, a traditional root crop in Ireland, sensitive to water stress and also a staple of the tillage production sector, the impact of climate change on yield was determined using simulation models (in the DSSAT package) and downscaled output from a general climate model. Daily weather data stochastically generated from mean monthly values for baseline (1961-1990), 2055 (2041-2060) and 2075 (2061-2090) climate periods were derived for over 500 locations in Ireland (derived from HADCM3Ga1). Important points with respect to the expected change in climate were that rainfall becomes more seasonally extreme, and a relatively uniform increase in temperature of about 1.6 • C over the country can be expected by the 2075 climate period. This change in climate is predicted to cause little change in the geographical distribution of barley yield, but grain yield in all areas is expected to increase with possibly a greater increase to the west. Potato yield in 2055 and 2075 is expected to fall for non-irrigated tubers. The impact is likely to be a severe loss of yield over most of the country by 2055. The implications of these findings are that barley will remain a viable cereal crop, and might find a greater role in livestock supplement feed supply (due to predicted drought losses effecting grass yield), but the irrigation demand for potato will be very significant, possibly making the crop non-viable for farmers, particularly in the east of Ireland where there will be competition for water in summer.

“…Generally, C 3 crops in northern temperate environments are expected to benefit substantially from elevated atmospheric CO 2 concentration and moderate warming when water is not limiting [3][4][5][6]. This positive effect has been found to arise mainly from greater biomass production and grain number [8,12,15,16] and, to a lesser extent, from increased grain weight due to interactions between CO 2 , temperature and water on the duration and effectiveness of grain filling and canopy senescence [15].…”

This paper assessed the effect of projected climate change on the grain yield of barley in fourteen administrative regions in the United Kingdom (UK). Climate data for the 2030s, 2040s and 2050s for the high emission scenario (HES), medium emissions scenario (MES) and low emissions scenario (LES) were obtained from the UK Climate Projections 2009 (UKCP09) using the Weather Generator. Simulations were performed using the AquaCrop model and statistics of simulated future yields and baseline yields were compared. The results show that climate change could be beneficial to UK barley production. For all emissions scenarios and regions, differences between the simulated average future yields (2030s-2050s) and the observed yields in the baseline period ranged from 1.4 to 4 tons·ha −1 . The largest increase in yields and yield variability occurred under the HES in the 2050s. Absolute increases in yields over baseline yields were substantially greater in the western half of the UK than in the eastern regions but marginally from south to north. These increases notwithstanding, yield reductions were observed for some individual years due to saturated soil conditions (most common in Wales, Northern Ireland and South-West Scotland). These suggest risks of yield penalties in any growing season in the future, a situation that should be considered for planning adaptation and risk management.
