(Peer reviewed; Journal article, 2022-01)Urban agriculture is increasingly recognized as an important sustainable pathway for climate change adaptation and mitigation, for building more resilient cities, and for citizens’ health. Urban agriculture systems appear ... -
Variability in greenhouse gas emission intensity of semi-intensive suckler cow beef production systems
(Peer reviewed; Journal article, 2020-05-20)Emission intensities from beef production vary both among production systems (countries) and farms within a country depending upon use of natural resources and management practices. A whole-farm model developed for Norwegian ... -
Variability in the Content of Phenolic Compounds in Plum Fruit
(Peer reviewed; Journal article, 2020-11-20)The aim of this study was to determine the composition and content of phenolic compounds in extracts of plum fruit. Fruit of 17 plum cultivars were analyzed. Fruit samples were collected in 2019 from fruit trees with ... -
Variability in the Water Footprint of Arable Crop Production across European Regions
(Journal article; Peer reviewed, 2017-02-08)Crop growth and yield are affected by water use during the season: the green water footprint (WF) accounts for rain water, the blue WF for irrigation and the grey WF for diluting agri-chemicals. We calibrated crop yield ... -
Variability of Major Phenyletanes and Phenylpropanoids in 16-Year-Old Rhodiola rosea L. Clones in Norway
(Peer reviewed; Journal article, 2020-07-30)Rhodiola rosea L. (roseroot) is an adaptogen plant belonging to the Crassulaceae family. The broad spectrum of biological activity of R. rosea is attributed to its major phenyletanes and phenylpropanoids: rosavin, salidroside, ... -
Variation in gluten quality parameters of spring wheat varieties of different origin grown in contrasting environments
(Journal article; Peer reviewed, 2015-02-15)The aim of this study was to investigate variation in protein content and gluten viscoelastic properties in wheat genotypes grown in two mega-environments of contrasting climates: the southeast of Norway and Minnesota, ... -
Variation in rate of phenological development and morphology between red clover varieties: Implications for clover proportion and feed quality in mixed swards
(Journal article; Peer reviewed, 2019-05-28)Red clover (Trifolium pratense) grown in mixtures with grasses often constitutes a lower proportion of total yield in spring than in summer growth. A more even red clover proportion between the harvests would benefit forage ... -
Variations in biomass of fungal guilds are primarily driven by factors related to soil conditions in Mediterranean Pinus pinaster forests
(Peer reviewed; Journal article, 2022-01-30)Soil fungi are vital for regulating ecosystem carbon balance and productivity, by driving processes related to soil carbon and nutrient cycling. The rate and capacity of fungi-mediated processes are linked to fungal biomass ... -
Variations in nitrogen utilisation on conventional and organic dairy farms in Norway
(Journal article; Peer reviewed, 2017-06-22)Reduced N-surpluses in dairy farming is a strategy to reduce the environmental pollution from this production. This study was designed to analyse the important variables influencing nitrogen (N) surplus per hectare and per ... -
Variations in polyphenol and heavy metal contents of wild-harvested and cultivated seaweed bulk biomass: Health risk assessment and implication for food applications
(Journal article; Peer reviewed, 2018-07-27)Seaweeds are increasingly used in European cuisines due to their nutritional value. Many algal constituents, such as polyphenols, are important antioxidants and thus considered beneficial to humans. However, many seaweed ... -
Variations of energy intensities and potential for improvements in energy utilisation on conventional and organic Norwegian dairy farms
(Journal article; Peer reviewed, 2017-06-17)abstract Due to the limited resources of fossil fuels and the need to mitigate climate change, energy utilisation for all human activity has to be improved. The objective of this study was to analyse the correlation between ... -
Varied diets, including broadleaved forage, are important for a large herbivore species inhabiting highly modified landscapes
(Peer reviewed; Journal article, 2020-02-05)Diet quality is an important determinant of animal survival and reproduction, and can be described as the combination of different food items ingested, and their nutritional composition. For large herbivores, human landscape ... -
