Qi YJ, Li WJ. A Nested Property Right System of the Commons: Perspective of Resource System-Units. Environmental Science & Policy [Internet]. 2021;115(1):1-7. 访问链接Abstract
The common pool resource (CPR) theory has made invaluable contributions to the governance of natural resources in the past decades, but few literatures have specifically paid attention to the different property right arrangements of resource system and resource units, and their relationship. In this paper, we take two types of grassland property right system on the Qinghai-Tibetan Plateau (QTP) in China, one is grassland contract system under that the previous grassland common use was given up and the other is grazing quota system under that the common use is still kept in the community level, as cases to present the different consequences on the ecological conditions, herders’ livelihoods and livestock husbandry. Furthermore, from the perspective of property rights of resource system-units, we explore why the two systems resulted in the different consequences. We find that the grazing quota system indicated by the number of livestock each household allowed to raise has more advantages in improving the herders’ livelihoods and reducing the livestock production costs, and both systems could alleviate the grazing pressure though the long-term effects of the contract system might be negative on ecological conditions. The main reason why the grazing quota system works better is that this type of individual use rights were clarified based on the resource units so the grassland could be kept common use as an integrated resource system, while the contract system was claimed by physically dividing the resource system by fencing, thus the resource system was fragmented which led to mismatch with the large scope movement needs of livestock grazing. We argue that, theoretically, the grazing quota system is a private property rights embedded in the grassland common property right system, which forms a nested property right regime. Our findings have important implications for both of the CPR theory and practical rangeland management worldwide.
Gongbuzeren, Li WJ, Lai YP. The Role of Community Cooperative Institutions in Building Rural–Urban Linkages Under Urbanization of Pastoral Regions in China. Frontiers in Sustainable Food Systems [Internet]. 2021;(4). 访问链接Abstract
In contrast to agricultural settings, the process of urbanization in the pastoral regions of China are largely driven by long-term influences of ecological conservation and the provision of social services. Consequently, many of the herders who have migrated into nearby secondary urban centers depend on resources from pastoral regions to support their livelihoods, forming complex patterns of rural–urban linkages. While current literature has discussed the processes of herder out-migration and their implications on rural and urban livelihood development, few studies have examined the linkages between the herders living in the pastoral regions and those who have out-migrated to urban regions and their importance in rural livelihood transformation. Based on past studies, we argue that, in a changing pastoral social–ecological system, herders living in both rural and urban regions depend on each other to support their livelihoods through three types of mobility: (1) livestock mobility, (2) herder mobility, and (3) resource mobility. However, what innovative institutions in rangeland resource management and herder economic cooperation can do to help maintain these three types of mobility to sustain rural livelihood development, becomes a critical challenge. Innovative community cooperative institutions developed by pastoral communities from the Tibetan Plateau and Inner Mongolia may be able to offer new perspective and insight on how to better maintain rural–urban linkages in the processes of urbanization in pastoral regions. In this current study will present the two cases of innovative institutions and the roles they play in facilitating the three types of mobility to address livelihood challenges. While current studies recommend an increase of government subsidies, provision of vocational training, and social insurance that help herders better adapt to urban livelihood, we argue that rangeland management and community economic cooperation in innovative institutions are needed to facilitate the mobility of livestock, resources, and the herder population, and maybe only then the livelihood challenges that migrated herders are facing will be addressed effectively.
Li YB, Li WJ. Do fodder import and credit loans lead to climate resiliency in the pastoral social-ecological system of Inner Mongolia?. Ecology and Society [Internet]. 2021;26(1):27. 访问链接Abstract
Mainstream policies encourage pastoralists to apply credit loans and input exogenous fodder to alleviate the stress caused by climatic variability and uncertainty. Such external inputs induce new driving forces to the coupled pastoral social-ecological system (SES), but their long-term impacts are not fully understood. Taking Sonid Left Banner of Inner Mongolia as a case study area, we applied an agent-based model and Monte Carlo simulation to evaluate the impacts of fodder import and credit loans on the resilience of pastoral SES in terms of pastoralist household livelihood, livestock production, and rangeland health. The results showed that the strategy of importing fodder only in natural disaster years could make the pastoral SES more resilient to climatic variability, while frequent importing of fodder in climatically normal years would increase the vulnerability of the pastoral SES. Credit loans could enhance the resilience of the pastoral SES in general if fodder is not imported or only imported in disaster years, but could reduce the resilience if fodder is imported frequently. Our findings revealed several differences with previous research on fodder input and credit loan effects, indicating that relevant policies should be holistically evaluated from the perspective of social-ecological systems.
李名镜, 祁应军, 李文军. 生计和生态视角下搬迁牧户保有牲畜的行为研究——以青海省玉树州搬迁牧户为例. 北京大学学报(自然科学版). 2021;5.Abstract
为理解牧区城镇化背景下,搬迁牧户保有牲畜的行为逻辑及其生态影响,以青海玉树州三个村的搬迁牧户为例,通过问卷调查和访谈获取数据,分析牧民在迁出地保有牲畜的具体形式、原因和数量变化及牧民的生态感知,并根据斯科特关于道义小农的“安全第一”原则选择变量,定量探究牧民保留牲畜行为和数量的影响因素。研究发现,搬迁牧户通过家庭分工、亲友代养、雇工放牧等多种形式保有牲畜,作为融入城镇生活的适应性策略。牧户保有牲畜主要是出于“安全第一”的需求,经济收入较高的牧户兼具“理性小农”的特点。家庭人口规模大、非生计原因搬迁的牧户更倾向于保有牲畜。收入较高的牧户保有牲畜的概率更高且数量更多,而城镇就业人数较多的家庭保有牲畜的概率更低。牧户保有牲畜的适应策略受到社会关系、经济成本等因素的制约,可能难以维持。搬迁牧户保有牲畜的行为并未直接增加迁出地的放牧压力,但鼓励牧民搬迁以实现减畜目标的政策执行需要关注搬迁牧户保有牲畜的形式、返迁的可能性、行为动机的转变和留居户的牲畜数量变化。
