Rangeland degradation and vulnerability of livelihoods are two major challenges facing pastoralists, rangeland managers and policy-makers in arid and semi-arid areas. There is a need to make holistic informed decisions in order to protect rangelands and sustain livelihoods. Through a comprehensive literature review on rangeland management policies and livelihood strategies of ‘rangeland users’, it is shown how such policies have affected sustainable rangeland management, how strategies to sustain livelihoods have been incomplete and how there has been a lack of a multi-disciplinary approach in acknowledging them. Accordingly, a set of appropriate livelihood alternatives is introduced and, thenceforth, a framework for their evaluation is developed. Supportive strategies for enhancing resilience are discussed as a research and policy-making gap. In this study, the keys to achieve sustainable livelihoods are acknowledged as ‘livelihoods’ resilience’, where livelihoods need to be supported by access to capital, means of coping with the contexts of vulnerability as well as by enhancing policies, institutions and processes. The paper proposes a set of ‘livestock-based livelihoods’ regarding ‘traditional pastoralism’ as well as ‘their mitigation and adaptation’. Moreover, their transformation to ‘commercial pastoralism’, ‘resource-based livelihoods’, ‘alternative livelihoods’ and ‘migration’ strategies is recognised to be employed by rangeland users as useful alternatives in different regions and under future changing conditions including climate change. These strategies embrace thinking on resilience and are supported by strategies that address social and ecological consequences of climate change consisting of mitigation, adaptation and transformation. It is argued that sustainable livelihoods and sustainable rangeland management will be achieved if they are supported by policies that build and facilitate a set of appropriate livelihood alternatives and keep them in a sustainable state rather than being limited to supporting ‘vulnerable livelihoods’. Finally, future directions for analysing and policy-making in selecting the best alternative to achieve sustainable livelihoods are indicated.

Для дальневосточных регионов российско-китайского приграничья на сегодняшний день значимы некоторые, не совсем благоприятные социальные тенденции, связанные с ухудшением различных аспектов повседневной жизни людей, включая плохое состояние социальной инфраструктуры, наличие больших трудностей в сфере труда и занятости, снижение реальных доходов населения и пр. В своём исследовании мы опирались на вторичный социологический анализ (в том числе с использованием статистических данных) и количественные методы (анкетный опрос). В целом выявленные проблемы и тренды существенно влияют на физическое и духовное воспроизводство населения. Их следует учитывать в качестве факторов, воздействующих на социальное условия жизни и миграционные стратегии жителей Дальнего Востока, что является принципиально важным для планирования региональной социальной политики. For the Far Eastern regions of the Russian-Chinese border to date, some important, not very favorable social trends associated with the deterioration of various aspects of the daily lives of people, including the poor state of social infrastructure, presence of major difficulties in the field of labor and employment, reduced real incomes, etc. In our research, we relied on secondary sociological analysis (including statistical data) and quantitative methods (questionnaire survey). In general, the identified problems and trends significantly affect the physical and spiritual reproduction of the population. They should be taken into account as factors that affect the social well-being and migration strategies of residents of the Far East, which is fundamentally important for planning regional social policy.

In recent years the analysis of individual communities in England has shed increasing light on their economic, social, demographic, cultural and religious development during the three centuries prior to the Industrial Revolution. Contemporaneously, and to some extent resulting from these local studies, there has been a growing interest in the family and patterns of inheritance. Similarly, among social anthropologists there has been the development of the concept of ‘strategy’ with writings on marriage, fertility, inheritance and migration strategies, although these may be regarded as components of general family strategies. Whereas in some writings strategies are shown as being pursued by individuals for their own purposes, others focused on family strategies, particularly ones designed to keep a family landholding from being divided. However, whether these studies of social organization in continental Europe and Asia can be applied to the English experience remains to be seen. To begin with they are all concerned with peasant landholding and as such may not be appropriate to the English experience where the debate on whether a peasantry even existed was begun by Macfarlane's The origins of English individualism in 1978.Secondly, there is no universal agreement on what kind of strategies were being followed, either individualistic or familial. Thirdly, there remains the question as to whether the strategies were intentional and the outcome of rational decision-making, or subconscious and rooted in implicitly accepted and long-established principles. These could have been that a landholding should remain undivided, that men had primacy over women in inheritance, that primogeniture would be practised and that younger brothers would not challenge their eldest brother's inheritance. A refinement of these approaches has been the view that family strategies could be very different. Some may have wished to hold on to the family estate and pass it on to the next generation. Others wanted to enlarge it and may have needed to do so for familial reasons, and yet more families may have wanted to create an estate where none yet existed. But in all cases, it is stated, there were families consciously planning and pursuing a strategy for the benefit of future generations. Furthermore, it is said that these strategies could only be pursued by families above the level of the poor and only became possible in western Europe in the sixteenth century as a result of changing attitudes and growing individualistic commercialism.
