金瑛, 李文军. 自发型与政策型移民搬迁对牧民生计的影响——以青海省玉树州囊谦县两村为例. 北京大学学报(自然科学版) [Internet]. 2019;55(6):1119-1128. 访问链接Abstract
为了更好地理解牧区移民现状,对西部牧区普遍存在的自发型和政策型两种移民搬迁模式进行对比研究。选取青海省玉树州囊谦县的两个村为案例地,通过田野调查,采用半结构式访谈、问卷调查及关键人物访谈的方法开展研究。结果显示,政策型移民搬迁的搬迁规模更大,时间更集中,但自发型移民搬迁的牧民在寻找替代生计方面更成功,牧民返乡意愿更低。进一步采用多层次的牧民迁移决策分析框架,从宏观、微观和中观层次,分别分析两种模式中牧民决策背后的机理,指出城市拉力和社会网络是自发型移民搬迁的主要影响因素,而政策型移民搬迁主要受牧区推力和政府补贴影响。据此提出政策建议:将政府的一次性补贴转变为能够提高牧民可持续生计能力的形式,拒绝"一刀切"式规划,帮助潜在搬迁牧民构建与迁入地的社会网络关系。 
Talinbayi S, Xu HG, Li WJ. Impact of yurt tourism on labor division in nomadic Kazakh families. Journal of Tourism and Cultural Change [Internet]. 2019;11(3):339-355. 访问链接Abstract
Tourism’s impacts on ethnic cultures have received much attention, but few studies have been done on its impacts on nomadic people, especially for Kazakh nomads in China. Many Kazakh households are experiencing a transition from pastoralism to tourism, with yurt tourism being the popular Kazakh tourism products. This study takes Narat in China as a case to understand the impact of yurt tourism on the gendered labor division of Kazakh families, and the status of Kazakh women. Observations and semi-structured interviews were adopted. We find that the division of labor in yurt tourism is an extension of traditional nomad labor division and that the traditional gender statuses have been reinforced. Women are required to not only work but also face additional social pressure since they are considered to be going against customary rules when greeting tourists. Despite this, women’s self-confidence, business skills, and income have improved since the development of tourism. We argue that the form of tourism product, ideology of gender roles, and position of ethnic families in the tourism market account for this change. Diverse results of tourism impacts on the gender relationships of ethnic communities can be derived from the interactions of these three factors.
Zhuang M, Gongbuzeren, Gongbuzeren, Li W. Community-based seasonal movement grazing maintains lower greenhouse gas emission intensity on Qinghai-Tibet Plateau of China. Land Use Policy [Internet]. 2019;85(6):155-160. 访问链接Abstract
Global livestock husbandry provides ecosystem goods and services but also emits 7.1 Gt CO2-eq. of greenhouse gases (GHGs) per year. To lower GHG emissions intensity, appropriate production management systems should be identified. Since the 1980s, grassland livestock husbandry in China has transformed gradually from pastoralism into individual household management under the Grassland Household Contract System Policy. However, little is known about how this transition influences GHG emissions. We selected two case study sites representing two different forms of rangeland management systems in Ruoergai county of the Qinghai-Tibet Plateau, viz. 1) household-based all year continuous grazing under the individual use of rangeland with fences demarcating boundaries; 2) community-based seasonal grazing under the common use of the whole rangeland. The objective was to examine the differences in greenhouse gas emission intensity between the two systems using life cycle assessment (LCA). The results showed that the transition from community-based seasonal grazing into household-based continuous grazing increased the GHG emissions intensity from -0.62 kgCO2-eq/kg meat to 10.51 kgCO2-eq/kg meat. The increase was primarily attributed to changes in soil carbon storage. Findings suggest that to minimize GHG emissions and environmental degradation, community-based seasonal grazing in the pastoral area of Qinghai-Tibet Plateau should be maintained. Enhancing soil carbon sequestration by adopting appropriate practices would further reduce the GHG emissions intensity arising from the livestock system.
Li D, Hruska T, Talinbayi S, Li W. Changing Agro-Pastoral Livelihoods under Collective and Private Land Use in Xinjiang, China. Sustainability [Internet]. 2019;11(1):166-186. 访问链接Abstract
After the founding of P. R. China, land use in rural China was organized under two successive paradigms: state-directed collectivization from 1958–1984 (the Collective Era), and privatization after 1984 (the Household Land Contract Period, HLCP). Taking Nileke County of Xinjiang as a case study, this research analyzed the livelihood changes of agro-pastoralists over the two periods using quantitative household livelihood assets—financial, physical, natural, human, and social capital—as indicators. Using annual series data of the five livelihood capitals, a comprehensive livelihood assets index (CLAI) was calculated by two-stage factor analysis. Higher CLAI scores meant better living and reduced poverty for agro-pastoralists. Quantitative results were validated and detailed with semi-structured household interviews. The results showed that CLAI slightly increased during the HLCP in comparison to the Collective Era, mainly due to increases in financial and physical capital. In contrast, natural and social capital showed downward trends, indicating that alleviation of poverty came at the cost of natural resources and social justice. Natural capital was the main contributor to agro-pastoralist livelihoods during the Collective Era, but diminished and was replaced by financial capital during the HLCP. Based on the findings, we put forward policy suggestions to improve community land management and sustainable livelihoods as part of future poverty alleviation efforts.
