Abstract
This ESEE 2011 conference paper examines attitudes to private and public goods and bads from agriculture in Norway with a particular focus on organic agriculture. The issue is based on a survey among 939 Norwegians. The results show that the respondents strongly value public attributes of agriculture like a vivid countryside and cultural landscapes. Almost 60 percent of the sample emphasise that the government should aim to increase the production and sale of organic food. Respondents’ behaviour as consumers were investigated by collecting and analysing data that indicate which conditions respondents find most important when they buy milk, eggs, carrots and ketchup. Important conditions were taste, fresh, produced in Norway and no use of pesticides or fertilizers. The most important reasons for buying organic food were avoidance of pesticides, health and environmental concerns.
Abstract
The anticipated future changes in temperature, precipitation and snow cover caused by global warming may affect winter survival of autumn sown wheat. More variable weather conditions may cause an increased frequency of periods with alternating freezing and thawing and less stable snow covers. In the present study, the course of plant frost tolerance and growth potential was studied by exposing cold acclimated plants of winter wheat to conditions with alternating periods of freezing and thawing (either -1 °C or +5 °C), and differing durations of snow cover. Tests of frost tolerance and determination of growth potential were performed each time the temperature or snow cover conditions were changed. Periods without snow cover and + 5 °C caused dehardening, with loss of frost tolerance being more pronounced during the first dehardening period than in the second one. The ability to reharden after a dehardening period decreased towards the end of the experimental period. Mild periods during winter also seemed to exhaust plant growth potential, possibly by increasing respiration rate while photosynthesis was still restricted. The results indicate some of the challenges we may face regarding overwintering of winter wheat in a future climate.
