Publikasjoner
NIBIOs ansatte publiserer flere hundre vitenskapelige artikler og forskningsrapporter hvert år. Her finner du referanser og lenker til publikasjoner og andre forsknings- og formidlingsaktiviteter. Samlingen oppdateres løpende med både nytt og historisk materiale. For mer informasjon om NIBIOs publikasjoner, besøk NIBIOs bibliotek.

To obtain a general picture of the herbage zinc, iron and manganese concentrations and their relation to dietary requirements of ruminants on organic farms, we analysed soil and herbage samples from four regions in Norway. The soil median Zn, Fe and Mn concentrations were 0.18, 13 and 0.84 mg/L, respectively. The herbage median (10th-90th percentile) Zn, Fe and Mn concentrations (mg/kg) in herbage in the first cut were 19 (14-34), 50 (36-88), 34 (22-86) and in the second cut 21 (16-37), 84 (52-171) and 66 (

Herbage selenium ( Se) concentration is generally low in Norway. It is unknown whether feeding practices on Norwegian organic farms fulfil the dietary needs of Se and vitamin E for sheep and dairy cattle. Therefore we analysed Se in soil and herbage, and Se and vitamin E in animal blood in the indoor feeding season at 14 organic dairy and 14 organic sheep farms. The herbage Se concentration was low. Approximately 50 and 35% of all samples in the first and second cut, respectively, had Se concentrations belo

To evaluate the animal nutritional status of copper, molybdenum and cobalt on Norwegian organic farms, soil, herbage and animal blood samples were collected from 27 dairy and sheep farms and analysed for Cu, Mo and Co. The herbage median (10th - 90th percentile) Cu,Mo, and Co concentrations (mg/kg DM) and the Cu: Mo ratio in the first cut were 5.3 (3.9 - 6.8), 1.5 (0.6 - 4.8),

The evaluation of water bodies "at risk" of not achieving the Water Framework Directive"s (WFD) goal of "good status" begs the question of how big a risk is acceptable before a programme of measures should be implemented. Documentation of expert judgement and statistical uncertainty in pollution budgets and water quality modelling combined with Monte Carlo simulation and Bayesian belief networks, make it possible to give a probabilistic interpretation of "at risk". Combined with information on abatement costs, a cost-effective ranking of measures based on expected costs and effect can be undertaken. Combined with economic valuation of water quality, the definition of "disproportionate cost" of abatement measures compared to benefits of achieving "good status" can also be given a probabilistic interpretation. Explicit modelling of uncertainty helps visualize where research and consulting efforts are most critical for reducing uncertainty. Based on data from the Morsa catchment in South-Eastern Norway, the paper discusses the relative merits of using Bayesian belief networks when integrating biophysical modelling results in the benefit-cost analysis of derogations and cost-effectiveness ranking of abatement measures under the WFD. Keywords: Benefit-cost analysis; Disproportionate costs; Eutrophication; Programme of measures.

Oil transportation along the coastline of northern Norway has been one of the hottest topics discussed in the Barents Region for the recent two years. It is also an important issue of today"s political agenda and bilateral discussion between Norway and Russia. This Report is an extended and updated version of a similar report published back in 2003. The purpose of this new edition is to provide the reader with new and additional information. We believe this is of crucial importance as the organisation of the oil shipment through the Barents Sea is constantly changing. The new report presents the ongoing oil transportation activities in the Russian part of the Barents Region. Moreover, the report gives an overview of the existing reserves of hydrocarbons, oil production facilities, transportation routes (oil loading terminals, transshipment schemes, export routes) and transport systems (railways, waterways and pipelines), as well as some environmental aspects of the oil shipment (environmental policies and prevention systems). The authors also give their reflections and comments about oil transportation safety, and point out factors tat they believe are essential to achieve efficient oil spill protection inside the Russian Barents and further along the Norwegian coast. The report is prepared and published by Bioforsk Svanhovd (former Svanhovd Environmental Centre) with support from the Norwegian Barents Secretariat and the WWF Arctic Programmme. The report is also available in Russian.
