This paper aims to provide an overview of experience for sustainable water management in Norway. It covers professional areas of integrated water management including urban stormwater management, hydropower development and environment protection, hydrological data collection and flood control, soil erosion and control measures from agricultural areas, ecosystem conservation in river catchments and sediment transportation, and the long-term development of climate change. Water management should be systematic and predictable, and based on the principle of legality. Selected central acts regulating water management aspects, important regulations including regulations on drinking water, sewage purification, licence fees, safety and supervision of watercourse installations were reviewed. The recognition of the economic value of water is visible in many parts of Norwegian water legislation. Several aspects of urban stormwater management, as a whole of integrated water management, were highlighted in part 1 of the paper. Hydropower development related regulations concerning on environment protection were described in part 2. Floods caused by typical climate in Norway, structural and non-structural measures to mitigate floods were summarised in part 3. Erosion from agricultural areas, control measure, monitoring system were summarised in part 4. Research regarding erosion process in river catchments, glacial erosion, and erosion in clay areas, mountain and arctic rivers, and sediment transportation in rivers were presented in part 5. Climate development in Norway during 1900-2100 was given in the last part of the paper, where regional climate downscale models, empirical and dynamical downscaling, were introduced. Results of climate variation - temperature and precipitation in Norway in the latest 100-150 years and scenarios of climate development during the 21st century were presented.

The Norwegian Ministry of Foreign Affairs (MFA) has been funding an NORWEGIAN SOUTH EASTERN EUROPE (SEE) PROGRAMME IN AGRICULTURE; Competence transfer and institutional contact and co-operation between faculties of Agriculture, Forestry and Veterinary Medicine in South Eastern Europe, (2002 ?2005). The main objectives under this programme were: - To improve organising, content and quality of academic education and research in agriculture, veterinary medicine and forestry to meet with needs for qualified people in ongoing rebuilding after wars and to reach the general European level and standards. - Create functional and sustainable networks of regional institutions and professionals to support each other and cooperate for optimal use of limited available resources in the SEE region in a difficult rebuilding situation. The main activities were: - Research and development projects in the areas of animal sciences, crop and fodder production and use of GIS-methods in forestry and agriculture. - Support to development of staff and institutions in form of study stays, study material, covering of costs for laboratory analysis etc. related to M.Sc. and Ph.D. thesis work, guest lecturing and some equipment. - Support to reorientation of academic education in agriculture, forestry and veterinary medicine. - Support to regional networks, professional meetings, further development and use of the Programme web site and web-based teaching. The most important strategy in this Programme was to facilitate for institutional cooperation and network building between partners in the SEE area. Origin application (05/420-3, 07.12.06) to MFA, for budget of activities for the secon year 2007, was NOK 4.830.000. The MFA reduced applied budget approximately by 18%. Funding of NOK 4.000.000 was granted by the MFA for this program?s second year 2007. See UD bevilgningsbrev, 05/00396-12, from 19. April 2007, Appendix 1, page 48-51. According to the UD bevilgningsbrev budget and activities for the secon year 2007 wear redused, see NORAGRIC?s letter 05/420-3, 07.05.2007, e-mail 07.05.2007, page 45 and UD letter 05/00396-16, from 19 November 2007, page 46. See also e-mail Status report for UD Project nr. 2070061, 25.06.2007, page 47. The Norwegian University of Life Sciences (UMB), through Noragric, UMB?s Department for International Environment and Development Studies, has been responsible for the overall preparations, coordination and implementation of this programme. The programme?s Coordinator has also been part time active with scientific and education in several projects and activities. UMB/Noragric has been responsible for accounting and reporting for the programme. Programme activities include: ? Programme budgets for each projects and activities have been prepared. ? There have been preparations of agreements (54 agreements) between SEE/WB partners and Norwegian partners for the implementation of planned programme activities and transfer of funds for 2007. ? FINAL reports for the second year of the programme activities (2007) have been prepared ? for each of the 9 projects according to MFA?s template for project reporting.

Host tree terpenes can influence attraction of conifer-infesting bark beetles to their aggregation pheromones, and both synergistic and inhibitory effects have been reported. We tested a gradient of ratios of (–)-α-pinene, the predominant monoterpene in Norway spruce, to the pheromone of Ips typographus, a major pest of Norway spruce. Attraction of I. typographus increased as the release rate of (–)-α-pinene increased. The two highest (–)-α-pinene : pheromone ratios (526 : 1 and 2595 : 1) attracted twice as many I. typographus as pheromone alone, whereas low to intermediate ratios (56 : 1, 274 : 1) did not differ from pheromone alone. Our results are in agreement with a proposed model, which suggests that bark beetles display unique response profiles to host terpenes depending on the physiological condition of the host trees that they typically colonize. Ips typographus, which is an aggressive species capable of colonizing and killing healthy trees, showed an increased attraction to monoterpene : pheromone ratios, and this may be high enough to inhibit attraction of less aggressive beetle species typically colonizing dead, dying or stressed trees. Attraction of associates of I. typographus was also modified by (–)-α-pinene. Ips duplicatus, a competitor of I. typographus, showed increased attraction to the pheromone of I. typographus across all concentrations of (–)-α-pinene.

I artikkelen omtaler vi den amerikanske forvaltningsmodellen Recreation Opportunity Spectrum (ROS), og vi legger fram en firedelt modell for hvordan opplevelse og bruk av skog og utmark kan differensieres på areal.

Minced samples of cliff-fish from saithe during cold storage at 4 °C have been analyzed with fluorescence spectroscopy, and the amount of thiobarbituric acid reactive substances (TBARS) and total amount of volatile nitrogen (TVN) have been measured. Partial least squares regression models have been built between the fluorescence spectra and the chemical measured TBARS and TVN values. Both models were evaluated using full cross validation and test set validation. The correlation between the fluorescence spectra and TVN was 91% and the correlation between the fluorescence spectra and the TBARS was 79%, both using test set validation. The work has showed that fluorescence spectroscopy can be used as a rapid and non-destructive method for measuring TBARS and TVN in minced samples of cliff-fish from saithe with a high degree of accuracy.

Miljørapporten fra Landsskogtakseringen viser at gammel skog (etter valgte kriterier) utgjør om lag 6 prosent av produktivt skogareal i 2002, og at andelen gammel skog har vært økende siden 1991. Årlig tilgang død ved i perioden 2000-2004 har vært om lag 3,2 millioner kubikkmeter. Dette utgjør 5 prosent av total mengde død ved i 1996. Resultatkontrollen ble utført i 2005 av arealer avvirket i 2003. Omlag 23 % av arealet er ”ikke tilrettelagt” for naturlig foryngelse eller tilplantet ved kontrolltidspunktet. Andel planting har gått ned med ca. 4 %, mens arealet som forynges naturlig holder seg relativt stabilt sammenliknet med tidligere år. Resultater er også vist for kontroll av anlagte skogsveger og godkjente skogbruksplanprosjekter
