økologisk landbruk tilbyr en plattform for bærekraft bygd på fire grunnlegggende prinsipper om landbrukets bidrag til helse, økologi, rettferdighet og varsomhet. Dette er et viktig bidrag til en bærekraftig utvikling av alt norsk landbruk.

Abstract Introductions of the pine wood nematode (PWN), which causes Pine Wilt Disease (PWD), have devastating effects on pine forests in regions with susceptible host trees under suitable climate conditions. Norwegian authorities have proposed a contingency plan if PWN is detected in Norway. We compare the costs of implementing this plan with the costs of further spread and damage of PWN under two climate change scenarios: present and the most likely future climate. With the present climate, PWD will not occur in Norway. Under climatic change, the cost of PWD damage is approximately 0.078- 0.157 million NOK (0.01-0.02 million Euros) estimated as net present value with 2 and 4% p.a. discount rate. In contrast, the corresponding costs of implementing the suggested contingency plan will be 1.7-2.2 billion NOK (0.2-0.25 billion Euros). These costs are caused by reduced income from industrial timber production and the costs of the eradication measures. Costs related to reduced recreation or biodiversity are expected to be very high, but are not included in the above estimates. Many of the factors in the analysis are burdened with high uncertainty, but sensitivity analyses indicate that the results are rather robust even for drastic changes in assumptions. The results suggest that there is a need to revise the current PWN contingency plan in Norway. Keywords: Bioeconomics, boreal forest damage, Bursaphelenchus xylophilus, climate change, impact assessment, stochastic modelling.

Hensikten med studien var å sjå om eingongsvurdering av form på spenetupp og speneåpning på NRF-kyr i forskjellige stadium av laktasjonen virka inn på sannsynlegheita for at ein kjertel er infisert med mastittbakteriar. Totalt var 49 besetningar med i undersøkinga. Av desse var 24 økologiske og 25 konvensjonelle, og det var 19 båsfjøs og 30 lausdriftfjøs. Antall dagar i laktasjon eller mjølkemengde fire veker etter kalving hadde ikkje betydning for om ein kjertel var infisert eller ikkje. Derimot var det ein samanheng mellom infiserte kjertlar og forekomst av ru spenering, innkrenga og tilspissa spenetupper, bakjertlar, kua sin alder og celletal. Tidligare har det vore rapportert om 43% flate, 45% runde og 12-13% traktforma ender på spenetuppene på Norsk rødt fe. Det er godt samsvar mellom denne studien og vår studie når det gjeld forekomsten av flate og runde spenetupper. Neijenhuis et al. (2001) rapporterte at traktforma spenetuppar hadde tjukkare og meir ru spenering enn flate og innkrenga spenetupper. Det er rapportert at kyr med innkrenga spenespissar har høgare risiko for lekkasje som igjen er knytta til høgare risiko for mastitt og høgt celletal, medan andre har rapportert at det ikkje er samanheng mellom form på spenetupp og celletal.

The process of minimising medicine use through dialogue based animal health and welfare planning. Livestock are important in many organic farming systems, and it is an explicit goal to ensure high levels of animal health and welfare (AHW) through good management. In two previous EU network projects, NAHWOA & SAFO, it was concluded that this is not guaranteed merely by following organic standards. Both networks recommended implementation of individual animal health plans to stimulate organic farmers to improve AHW. These plans should include a systematic evaluation of AHW and be implemented through dialogue with each farmer in order to identify goals and plan improvements. 11 research institutions in 7 European countries have been involved in the ANIPLAN project with the main objective to minimise medicine use in organic dairy herds through active and well planned AHW promotion and disease prevention. The project consisted of 5 work packages, 4 of which comprised research activities building on current research projects, new applications across borders, exchange of knowledge, results and conclusions between participating countries, and adopting them to widely different contexts. International and national workshops have facilitated this exchange. In the project, animal health and welfare planning principles for organic dairy farms under diverse conditions were developed. Animal health and welfare assessments, based on the WelfareQuality parameters, were conducted in different types of organic dairy herds across Europe. Finally, guidelines for communication about animal health and welfare promotion in different settings were also developed relevant to both existing animal health advisory services or farmer groups such as the Danish Stable School system and the Dutch network program. These proceedings contain the presentations at the final workshop, which also included invited external guests. The proceedings also contain three reports which are deliverables of the project. They are focused on the process of planning for better animal health and welfare, and how farmers and facilitators manage this situation. The focus areas are animal health planning, AHW assessment using animal based parameters and development of advisory systems and farmer groups.
