Background Since the late 1800s, an unknown number of common pheasants and grey partridges from captive bred stocks have been released in Norwegian nature. The birds are released to be used for training of pointing dogs. The import, keeping and release of gamebirds, as well as the management of release sites, have been largely unregulated. The consequences to biodiversity, animal health and welfare have not been investigated. The Norwegian Environment Agency (NEA) and the Norwegian Food Safety Authority (NFSA) have jointly requested the Norwegian Scientific Committee for Food and Environment (VKM) for a scientific opinion on the release of common pheasants and grey partridges for pointing dog training regarding consequences for biodiversity, animal welfare of the released birds and health of the released birds as well as wild birds to which pathogens may be transmitted. VKM was further asked to suggest risk reducing measures for biodiversity and animal welfare. Methods VKM established a project group with expertise within avian ecology, landscape ecology, population biology, wildlife veterinary medicine and animal welfare. The group conducted systematic literature searches, scrutinized the resulting literature, and supplemented by other relevant articles and reports. In the absence of Norwegian studies, VKM used literature from other countries where common pheasants and grey partridges (and in some cases other gamebirds), are released, as references. The project group applied observation data of common pheasants and grey partridges in Norway for the period 2000-2022, presented by the Norwegian Biodiversity Information Centre (NBIC). In the assessments, VKM assumed that the release of birds will be in the same order of magnitude as in previous years (a few thousand birds annually on a national level). The number of release sites and the density of released birds per site are unknown. Increasing the number and density of birds would also increase the probability of negative effects and the severity of the consequences. VKM assessed the impacts of released common pheasants and grey partridges on competition, predation, hybridization, transmission of disease, herbivory and indirect impacts through interactions with other species (predator abundance and pathogen-mediated competition). VKM also assessed the impact on biodiversity in a 50-year perspective. Furthermore, VKM discusses how the birds’ welfare might be impacted by rearing, transport, release and exposure to pointing dogs. Finally, VKM provides a list of relevant diseases and assessed their potential impact on animal health during transport, rearing and release. Results and conclusions VKMs assessment show that there are several risks to biodiversity, animal health, and animal welfare from the release of captive bred common pheasants and grey partridges in Norway. The risk of increased competition for food, particularly in winter, with birds with similar niches as common pheasants and grey partridges, is low on a national scale and moderat on a local scale. This is particularly so for yellowhammer, Emberiza citronella, a species categorized as vulnerable on the national red list due to its progressive population decline caused by reduced availability of food during winter. There is a moderate risk for predation on invertebrates and negative impacts on flora. Indirectly, activities connected to the release of birds may lead to moderate risks of altered predator abundance and disease-mediated competition. VKM concludes that the ecological impacts will be more severe for redlisted species present within the release areas for common pheasants and grey partridges. Repeated release of common pheasants and grey partridges can lead to high risk of disease transmission to wild birds. .............
Abstract
The worldwide decline in bees and other pollinating insects is a threat to biodiversity and food security, and urgent action must be taken to stop and then reverse this decline. An established cause of the insect decline is the use of harmful pesticides in agriculture. This case study focuses on the use of pesticides in Norwegian apple production and considers who among farmers, consumers and public authorities is most responsible for protecting bees against harmful pesticides. The extent to which these three different groups consider themselves responsible and the degree to which they are trusted by each of the other groups are also studied. This empirical study involves both qualitative interviews with Norwegian apple farmers, consumers and public authorities and survey data from consumers and farmers. The results show that consumers consider public authorities and farmers equally responsible for protecting bees, while farmers are inclined to consider themselves more responsible. Farmers, consumers and public authorities do not consider consumers significantly responsible for protecting bees, and consumers have a high level of trust in both farmers and public authorities regarding this matter. This study also finds that a low level of consumer trust in farmers or public authorities increases consumers’ propensity to purchase organic food, suggesting that those who do not trust that enough action is adopted to protect the environment take on more individual responsibility. This paper adds to the existing literature concerning the allocation of responsibility for environmental outcomes, with empirical evidence focusing specifically on pesticides and bees.

The objective of this report is to investigate the role of animal breeding in the partner European countries — in terms of (1) increase of the competitiveness of breeders’ association and (2) conservation of animal genetic resources including breeding programmes — to generate relevant lessons for African partner countries in addressing livestock and poultry productivity and quality challenges in Africa.

Divina Gracia P. RodriguezAbstract
Human urine contains essential nutrients (e.g., nitrogen and phosphorus) required for plant growth. Hence, urine can serve as a “free” and locally available nutrient source. Successful, low-cost urine-diverting toilets (UDTs) that separately collect urine have been developed in Scandinavia and in Europe and are being manufactured at large-scale in Africa. There exists many barriers to urine recycling at scale. The important initial steps for increased use of urine as a fertilizer (UBF) are to understand the technical, socio-cultural, economic, institutional and ecological aspects that affect large-scale adoption of UDTs, urine treatment technologies, and UBFs; provide evidence-based data that shows urine is safe in terms of heavy metals, pathogens, and organic micropollutants; and identify optimal combinations strategies to sustain adoption in the long term. FoodSecURe will be implemented and will utilize the already existing UDTs in communal public areas in Bahir-Dar, Ethiopia. Due to lack of technology and limited awareness of users, government and institutions, these UDTs were used inappropriately, and no UBF has been produced from the UDTs. The project will be conducted through 6 work packages (WPs): WP0 focuses on the project management. WPs 1-4 focus on identifying the barriers in the adoption of urine recycling based on technology (WP1), health (WP2), socio-culture and environment (WP3), and economic and institutions (WP4). The dissemination, exploitation and communication activities are in WP5. The various tasks are implemented through a multi-disciplinary and multi-actor approach by scientists specializing in social sciences, business management, agronomy, parasitology, environmental engineering, environmental science, and soil science. A Stakeholder Advisory Committee will be created to strengthen science-policy-stakeholder linkages and ensure that the technical and socio-economic solutions identified in the project match the stakeholders’ needs.

Plant genetic resources form the biological basis for all plant-based agricultural production. In the genetic diversity lie opportunities to adjust, improve and adapt the crop production to current or future needs. In addition, the diversity of species and varieties in Norwegian agriculture represents an important part of our cultural heritage. Conservation and sustainable use of plant genetic resources is a global concern and FAO has established a global action plan that highlights priorities for conservation and use of plant genetic diversity at national level. This report points to results, trends and challenges within this field in Norway and is the Norwegian contribution to the FAO report "Third State of the World's Plant Genetic Resources" (expected 2023).
