Abstract
Ruminants, including sheep, contribute significantly to methane emissions, thus resulting in high emissions per kg of product. However, they can utilise plant material unsuitable for human consumption, thereby transforming it into valuable, protein-rich food. Grazing also preserves cultural landscapes and can contribute to carbon sequestration. Under¬standing the balance between these factors within the climate change context is crucial. This study inves-tigates the environmental impact of meat, milk, and wool production from sheep farming in Norway and Slovenia.

Ruminants, including sheep, significantly contribute to methane emissions, which results in high emissions per kg of product. Conversely, ruminants can utilise plant material unsuitable for human consumption, effectively converting it into valuable, protein-rich food. Grazing also maintains cultural landscapes and contributes to carbon sequestration. Therefore, under- standing the balance between these factors in the context of climate change is essential. This study analyses the environmental impact of meat, milk, and wool production from sheep farming in Norway and Slovenia.

Small ruminant (sheep and goat) production of meat and milk is undertaken in diverse topographical and climatic environments and the systems range from extensive to intensive. This could lead to different types of welfare compromise, which need to be managed. Implementing Precision Livestock Farming (PLF) and other new or innovative technologies could help to manage or monitor animal welfare. This paper explores such opportunities, seeking to identify promising aspects of PLF that may allow improved management of welfare for small ruminants using literature search (two reviews), workshops in nine countries (France, Greece, Ireland, Israel, Italy, Norway, Romania, Spain, and the United Kingdom) with 254 stakeholders, and panels with 52 experts. An investigation of the main welfare challenges that may affect sheep and goats across the different management systems in Europe was undertaken, followed by a prioritisation of animal welfare issues obtained in the nine countries. This suggested that disease and health issues, feed access and undernutrition/malnutrition, maternal behaviour/offspring losses, environmental stressors and issues with agonistic behavioural interactions were important welfare concerns. These welfare issues and their indicators (37 for sheep, 25 for goats) were categorised into four broad welfare indicator categories: weight loss or change in body state (BWC), behavioural change (BC), milk yield and quality (MY), and environmental indicators (Evt). In parallel, 24 potential PLF and innovative technologies (8 for BWC; 10 for BC; 4 for MY; 6 for Evt) that could be relevant to monitor these broad welfare indicator categories and provide novel approaches to manage and monitor welfare have been identified. Some technologies had the capacity to monitor more than one broad indicator. Out of the 24 technologies, only 12 were animal-based sensors, or that could monitor the animal individually. One alternative could be to incorporate a risk management approach to welfare, using aspects of environmental stress. This could provide an early warning system for the potential risks of animal welfare compromise and alert farmers to the need to implement mitigation actions.

In the face of unprecedented challenges posed by the global COVID-19 pandemic, Resilience and Realities - Exploring Pandemic Effects, Governance Challenges, and Economic Insights offers a comprehensive exploration of the intricate interplay between public policies and uncertain times. This enlightening volume presents a thought-provoking collection of chapters that dissect the illusions, opportunities, and complexities surrounding public policies during crises. Spanning two captivating sections, this book embarks on a journey through the labyrinth of pandemic-related public policies, offering fresh insights into the ever-evolving landscape of economic responses and the resilient spirit of entrepreneurship. In the first section, “Illusions of Public Policies Amidst a Pandemic”, readers are invited to dissect the enigma of navigating uncertainties in crisis management. Delve into the gendered impact of the pandemic on academic women, explore the untapped opportunities within the pandemic’s wake, and scrutinize the efficacy of governmental economic strategies. The second section, “Public Policies towards Investment, Technology, and Efficiency”, provides an insightful investigation into the impact of investment in human capital on economic growth. Review the intricacies of financial management within the public sector and gain an understanding of the multifaceted dimensions of technology, investment, and efficiency in public policies. With each chapter, esteemed authors contribute their expertise to illuminate the complexities of these critical topics. Resilience and Realities - Exploring Pandemic Effects, Governance Challenges, and Economic Insights is a vital resource for policymakers, economists, academics, and curious minds seeking a deeper understanding of the intricate nexus between public policies and uncertain times. Explore the wealth of knowledge and insights within these pages and embark on a journey toward a more informed and resilient future. Discover illuminating perspectives, engage in thought-provoking analyses, and embrace the ever-changing landscape of public economics. This book stands as a beacon of knowledge and enlightenment in an era of unprecedented challenges.

Timothy ( Phleum pratense L.) is the predominant forage grass species in the northern parts of the Nordic region. Because of the long andharsh winters and a short growing season, most of it with continuous light, the need for locally adapted timothy seed has been recognizedfor more than a century. However, the seed production of timothy in these marginal environments is unpredictable with acceptable seedyield and quality on average only every third year. Thus, a multiplication scheme for the northern cultivars was established with only pre-basic seed produced in the north, and basic and certified seed produced further south to secure enough seed of good quality. In recentdecades this scheme has been more or less abandoned with continous generations produced in the south. Farmers are complaining andare questioning whether the cultivars has changed and lost winter hardiness. We studied freezing and ice-encasement tolerance of generations of the the northern timothy cultivars ‘Engmo’ (old landrace) and ‘Noreng’(synthetic) multiplied for one, two or three generations in Central, Southern and Northern Norway. The trials introduce very largedifferences in mean temperature, growing degree days and photoperiod between place of parental origin and sites of multiplication so theeffects on fitness observed could arise from both selection and and induced epigenetic changes. Large changes (loss) in freezing and ice-encasement tolerance were observed, especially at the southern location in the first generation.The cultivars behaved differently and there were significant interactions. The extreme phenotypic changes observed might be explained bygenetic selection or epigenetic memory of the environmental conditions experienced during seed production, or a combination of the two.We are currently analysing GBS data of all generations and this will be used to test whether genetic shifts has occured during themultiplication in the different environments.
