Norway has strong and competent institutions and lobby organisations for hydro and oil/gas. It has been difficult for renewables to reach the political agenda. The situation in 2007 is quite different compared with 10 years ago, now the knowledge about and political power of bioenergy is improved. The demonstration value of the Gardermoen project and the informational, educational and public relations work of the Energy Farm are important contributions to this changed situation. Climate change is of course another factor of large importance. The two case-studies, Gardermoen bioenergy plant and the Energy Farm, demonstrate that there are many other factors that prices/costs that influences bioenergy implementation.

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.

A main scourge in Norwegian sheep farming is tick-borne fever (TBF) caused by the bacteria A. phagocytophilum and transmitted by the tick Ixodes ricinus. The aim of this poster is to present a new research project on resistance to TBF in sheep (2007?2010).

The potential tradeoffs between vegetative and reproductive growth is a constant challenge for the forage plant breeders. Breeding for seed production has inevitably played a secondary role compared to improvements of the vegetative production. In this paper the current status regarding genetic variation, genotype x environment interactions, heritability estimates and mapping of quantitative trait loci (QTL) for seed yield and seed yield components in grasses and legumes are reviewed, with special focus on important forage grasses. Investigations of seed yield components have shown that components contributing to an increased utilization of the reproductive potential, like seed set and seed retention, seems efficient in increasing seed yield without adverse effects on the vegetative production. The generation of transgenic plants (GMO) have been reported for many forage species, and genetic engineering will increasingly be used to manipulate traits like nutritive value, resistance to fungal and viral diseases, and the reproductive system like male and female sterility and apomixis. Turf and forage grasses, and forage legumes are outcrossing species with prolific pollen production and pollination facilitated by wind or insects. They are potentially some of the most problematic crops when it comes to gene flow by pollen especially during the generations of seed multiplication. GM plants with engineered reproductive systems will pose new challenges for the seed producers. Co-existence of GM grasses and legumes with conventional and organic seed production will be very difficult to establish, and commercialization of GM cultivars will therefore certainly require gene containment technologies that prevent or reduce transgene escape. Mapping of QTLs, identification of markers and candidate genes associated with seed yield components, and the utilization of comparative genomics with cereal species have revealed several key components which may facilitate development of markers for marker-assisted breeding for the improvement of seed yield.
