Significant decrease in yield under future climate conditions: Stabilityand production of 138 spring barley accessions 21
Ingvordsen, Cathrine Heinz; Backes, Gunter; Lyngkjær, M.; Peltonen-Sainio, Pirjo; Jensen, Jens D.; Jalli, Marja; Jahoor, Ahmed; Rasmussen, Morten; Mikkelsen, Tesi N.; Stockmarr, A.; Jørgensen, Rikke Bagger.
tThe response in production parameters to projected future levels of temperature, atmospheric carbondioxide ([CO2]), and ozone ([O3]) was investigated in 138 spring barley accessions. The comprehensive setof landraces, cultivars, and breeder-lines, were during their entire life cycle exposed to a two-factor treat-ment of combined elevated temperature (+5°C day/night) and [CO2] (700 ppm), as well as single-factortreatments of elevated temperature (+5°C day/night), [CO2] (700 ppm), and [O3] (100–150 ppb). Thecontrol treatment was equivalent to present average South Scandinavian climate (temperature: 19/12◦C(day/night), [CO2]: 385 ppm). Overall grain yield was found to decrease 29% in the two-factor treatmentwith concurrent elevation of [CO2] and temperature,...

Grain protein concentration and harvestable protein under future climate conditions. A study of 108 spring barley accessions. 21
Ingvordsen, Cathrine Heinz; Gislum, René; Jørgensen, J.R.; Mikkelsen, Teis N; Jørgensen, R.B..
In the present study a set of 108 spring barley (H. vulgare L.) accessions were cultivated under predicted future levels of temperature and [CO2] as single factors and in combination (IPCC, AR5, RCP8.5). Across all genotypes, elevated [CO2] (700 ppm day/night) slightly decreased protein concentration by 5%, while elevated temperature (+5 °C day/night) substantially increased protein concentration by 29%. The combined treatment increased protein concentration across accessions by 8%. This was an increase less than predicted from strictly additive effects of the individual treatments. Despite the increase in grain protein concentration, the decrease in grain yield at combined elevated temperature and elevated [CO2] resulted in 23% less harvestable protein....

Climate Change Effects on Plant Ecosystems – Genetic Resources for Future Barley Breeding 21
Ingvordsen, Cathrine Heinz.
Climate Change Effects on Plant Ecosystems – Genetic Resources for Future Barley Breeding. A growing population and a considerable increase in living standards worldwide are increasing the demand on the primary production. At the same time, climate change is projected to lower the primary production due to increases in the atmospheric concentrations of carbon dioxide ([CO2]) and ozone ([O3]), rising temperatures and extreme climate events such as floods, storms and heatwaves. These predictions are compounded by the projections from the Intergovernmental Panel on Climate Change, which state that the world is heading towards a worst-case climate scenario unless actions are taken collectively in the very near future. Crop yields have stagnated since the start...

Eco-efficient production of spring barley in a changed climate: a Life Cycle Assessment including primary data from future climate scenarios. 21
Niero, Monia; Ingvordsen, Cathrine Heinz; Peltonen-Sainio, Pirjo; Jalli, Marja; Lyngkjær, M. F.; Haushildt, Michael Z.; Jørgensen, Rikke B..
The paper has two main objectives: (i) to assess the eco-efficiency of spring barley cultivation for malting in Denmark in a future changed climate (700 ppm [CO2] and +5 °C) through Life Cycle Assessment (LCA) and (ii) to compare alternative future cultivation scenarios, both excluding and including earlier sowing and cultivar selection as measures of adaptation to a changed climate. A baseline scenario describing the current spring barley cultivation in Denmark was defined, and the expected main deviations were identified (differences in pesticide treatment index, modifications in nitrate leaching and change in crop yield). The main input data originate from experiments, where spring barley cultivars were cultivated in a climate phytotron under controlled...

How to manage uncertainty in future Life Cycle Assessment (LCA) scenarios addressing the effect of climate change in crop production 21
Niero, Monia; Ingvordsen, Cathrine Heinz; Jørgensen, Rikke B.; Hauschild, Michael Z.
When Life Cycle Assessment (LCA) is used to provide insights on how to pursue future food demand, it faces the challenge to describe scenarios of the future in which the environmental impacts occur. In the case of future crop production, the effects of climate change should be considered. In this context, the objectives of this paper are two-fold: (i) to recommend an approach to deal with uncertainty in scenario analysis for LCA of crop production in a changed climate, when the goal of the study is to suggest strategies for adaptation of crop cultivation practices towards low environmental impacts, and (ii) to implement the suggested approach to spring barley cultivation in Denmark. First, the main implications of climate change for future crop...
