Individual age is an important element in models of population demographics, but the limitations of the methods used for age determination are not always clear. We used known-age data from moose (Alces alces), red deer (Cervus elaphus), semi-domestic reindeer (Rangifer tarandus tarandus) and Svalbard reindeer (Rangifer tarandus platyrhynchus) to evaluate the accuracy and repeatability of age estimated by cementum annuli analysis of longitudinally sectioned permanent incisors. Four observers with varying experience performed blind duplicate age estimation of 37 specimens from each cervid. The relationship between known age and estimated age was linear, except for Svalbard reindeer where a quadratic model gave a slightly better fit. After correcting for observer ID and animal ID, there was a slightly declining probability to assess the correct age with increasing age for moose, red deer and Svalbard reindeer. Across cervids and observers, estimated age equalled known age in 69% of all readings, while 95% age ± 1 year. Predicted probability of correct age assessment for experienced observers was 93% for red deer, 89% for Svalbard reindeer, 84% for moose and 73% for semi-domestic reindeer. Regardless of observer experience and cervid, there was a high agreement between repeated assessments of a given animal’s tooth sections. The accuracy varied between cervids but was generally higher for observers with former ageing experience with a given cervid. We conclude that the accuracy of estimated age using longitudinally sectioned incisors is generally high, and even more so if performed by observers with former ageing experience of a given species. To ensure consistency over time, a reference material from known-age individuals for each species analysed should be available for calibration and training of observers. Age determination .

When free-ranging animals encounter traffic on roads or railways, it may have fatal outcome. In Europe, collisions between vehicles and animals have increased the last 40 years, causing eco-nomic losses and serious welfare concerns. Today there is no technological solution to prevent such collisions in the rough, arctic climate that represents most parts of Norway. By using small and energy-efficient radio transmitters moulded into headcollars, researchers have now devel-oped and tested a system for warning traffic when semi-domestic reindeer are nearby the road. Tests on more than 700 reindeer over three consecutive winter seasons are promising.

This chapter provides a comprehensive literature review of sustainable bioeconomy development, with a focus on the definition, concepts, potential and risks involved. Countries differ on how they view bioeconomy, with some putting emphasis on sustainability and ecosystem services, while others focus on economic growth as the main goal. The literature review shows that bioeconomy is a rather new concept, at times its goals are conflicting, and its objectives are opposing. Hence, the lack of a common bioeconomy agenda and understanding across the globe will be one of the main constraints to achieve the UN Sustainable Development Goals (SDGs). However, bioeconomy brings the sustainable development discussions back onto the policy agenda, at both the national and international levels. There are sceptics who do not support this argument and claim that bioeconomy and SDGs do not go together and this is the agenda set by some industrialized countries and the corporate sector to suit their own interests. As the impacts of bioeconomy spread beyond country borders, a common agenda is necessary to keep the balance between the economic, environmental and social objectives. Experience of bioeconomy so far is limited and hence future development must be based on the strictly responsible, accountable and sustainable use of natural resources.

This book examines the bioeconomy concept, analysing the opportunities it can generate, the constraints and the potential benefits for society. The main objective of bioeconomy is to promote economic development, by creating jobs and enhancing the sustainable utilization of bio-resources. A primary driver of bioeconomy strategy, therefore, is the need to respond to the growing population's food and economic requirements. While today research and literature related to bioeconomy are limited, this book presents a unique collection of perspectives on the complex dimensions of the bioeconomy debate. Drawing on the experiences from Europe, Asia and Africa, it presents an international overview. The chapters address a wide range of issues, including coastal-land interactions, ecosystem services, food production, rural development, agriculture, forest management and bioenergy. As a whole, the volume outlines what role bioeconomy can play in contributing to the United Nations Sustainable Development Goals (SDGs) without compromising on the ecological sustainability and equitable distribution of benefits. The book concludes by providing recommendations for developing bioeconomy in respective sectors (agriculture, forestry, fisheries, renewable energy) and directions for planning future bioeconomy programmes and strategies. The Bioeconomy Approach will be of great interest to students and scholars of ecological economics, development economics and environmental economics, as well as policy-makers and practitioners involved in sustainable development.
