| 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... |

| A longer growing season and higher accumulated effective temperature sum (ETS) will improve crop production potential in Finland. The production potential of new or at present underutilised crops (e.g. maize (Zea mays L.), oilseed rape (Brassica napus L.), lucerne (Medicago sativa L.)) will improve and it will be possible to grow more productive varieties of the currently grown crops (spring wheat (Triticum aestivum L.), barley (Hordeum vulgare L.), oats (Avena sativa L.)). Also cultivation of autumn sown crops could increase if winters become milder and shorter, promoting overwintering success. Climatic conditions may on the other hand become restrictive in many ways. For example, early season droughts could intensify because of higher temperatures and... |

| The effects of climate change on plant pathogens could be roughly divided in three groups: 1) Direct effects on plant pathogens environment: on temperature and moisture during the growing season and winter. 2) Effects on host plant: increased CO2 level, autumn sown crops, abiotic stresses. 3) Indirect effects on plant pathogen: evolution of pathogens to better survive in changed environment. In this paper, the changes that have been observed in plant pathogen species on field crops in Finland will be discussed. |

| 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,... |

| Fungal plant pathogens causing cereal diseases in Finland have been studied by a literature survey, and a field survey of cereal leaf spot diseases conducted in 2009. Fifty-seven cereal fungal diseases have been identified in Finland. The first available references on different cereal fungal pathogens were published in 1868 and the most recent reports are on the emergence of Ramularia collo-cygni and Fusarium langsethiae in 2001. The incidence of cereal leaf spot diseases has increased during the last 40 years. Based on the field survey done in 2009 in Finland, Pyrenophora teres was present in 86%, Cochliobolus sativus in 90% and Rhynchosporium secalis in 52% of the investigated barley fields. Mycosphaerella graminicola was identified for the first time in... |

| In Finland, barley, Hordeum vulgare L., covers 50 % of the total acreage devoted to cereal cultivation. The most common disease of barley in Finland is net blotch, a foliar disease caused by the ascomycete Pyrenophora teres Drechsler. Disease resistance based on plant genes is an environmentally friendly and economical way to manage plant diseases caused by biotic stresses. Development of a disease resistance breeding programme is dependent on knowledge of the pathogen. In addition to information on the epidemiology and virulence of a pathogen, knowledge on how the pathogen evolves and the nature of the risks that might arise in the future are essential issues that need to be taken into account to achieve the final breeding aims. The main objectives of... |
