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.

The interdisciplinary study aims to contribute towards an increased knowledge base and dialogue between the stakeholders themselves and between researchers and stakeholders for addressing the impacts of climate change on rice farming in the Cauvery River Basin located in the peninsular part of India.

Global climate is supposed to get warmer the next decades. In Western Norway the average temperatures are suggested to increase about 1.0 ºC until 2050 and about 2.6 ºC until 2100, compared to 1980-2000. Data on strawberry yield were obtained from commercial strawberry growing in open field in the valley of Valldal in the fjord district of Norway for the years 1970-2000. These long time series were used for developing regression models to explain the effect of changing climate on harvest time for the strawberry cultivar ‘Senga Sengana". The mean temperatures per month for May, June, and July were crucial for the time of ripening. If the start of the harvest season was defined as the day of 5 % accumulated yield, the average date for the start of the season was about July 18 in this district for the last 40 years. According to the predicted climate change and the regression models the strawberry season will start on average 6 days earlier in 2050 and 22 days earlier in 2100 compared to the average of 1970-2000, provided that the cultivars are similar to ‘Senga Sengana" and that the cultural techniques are about the same as now. The harvest season was predicted to be on average about 4 days shorter in 2100 than in 1970-2000.

"CLIMATE: Adapating to extreme Weather in municipalities: what, how and why" er et strategisk instituttprogram med varighet fra 2006-2011. Prosjektet er et samarbeid mellom instituttene i Miljøalliansen; NIBR, NIKU, NILU, NINA, NIVA og Bioforsk Jord og miljø. ·CICERO - Senter for klimaforskning, har koordineringsansvar for prosjektet. Formålet med prosjektet er å øke forståelsen av, og å hjelpe kommunene med å håndtere utfordringer de vil stå over for ved ekstremvær. ·I prosjektet inngår anvendt forskning med fokus på problemstillingen lokale myndigheters håndtering av klimarelaterte ekstremhendelser (katastrofer). ·Klimarelaterte ekstremhendelser og konsekvenser kan eksempelvis være: hete, kulde, vind/stormer, ekstrem nedbør, flom, ras, snøskred, skogbrann, ødeleggelse av bygninger, veier, jernbane, tap/endret plante og dyreliv, forringelse av drikkevannskilder og sykdom. I for bindelse med prosjektet er det opprettet en nettside www.klimakmmune.no som blant annet inneholder faktaark om problemstillinger og tiltak, case-studier, støtte og veiledning til kommuner og resultater fra forskningsprosjekter (artikler og publikasjoner). Siden oppdateres fortløpende etter hvert som nye forskningsresultater kommer til.

Bilberry (Vaccinium myrtillus), also called European blueberry, is one of the most significant wild berries in the Nordic countries. The berries are recognized for their bioactive properties and distinctive aroma and flavor. The effects of climate on production and the quality of bilberries have been studied in a controlled experiment in a phytotrone using clonal material. In the experiment individual plants from two Northern clones and two Southern clones of bilberry have been grown at 12◦ and 18◦ C. At each temperature 3 different light treatments have been tested; 1) 24 hour (h) natural light (long day); 2) 24 h natural light with addition of red light and 3) 12 h light (short day). All plants were kept outside during flowering to ensure pollination by insects. Berries were sampled when ripe, weighed and stored at -80◦C for later analysis of carbohydrates, acids, phenols, anthocyanins and ascorbic acid. At 12◦C the two Northern clones produced the first ripe berries 5 weeks after pollination, while the two Southern clones needed an extra two weeks to ripening. This difference was most evident at the 24 hour day length treatment. At 18◦C both the Northern and Southern clones had ripe berries from 5 weeks after pollination. The results also indicate that the Northern clones produce better at long days, with and without addition of red light, compared to the Southern clones. The levels of fructose, glucose and sucrose are higher in berries developed at 12 than 18◦ C (means of all treatments and all clones). Also the level of citric acid, quinic acid, myo-inositol, gallic acid, cathecin, epigallocatechin, catechin derivates and quercetin are higher at the lowest temperature.
