Economic, policy, and climate changes have profoundly influenced pastoral social-ecological systems on the Tibetan Plateau. Climate change is believed to be leading to increasing extreme weather conditions such as snow disasters and droughts, putting a strain on the rangeland resources herders must have to increase income. Market-based economic reforms and interrelated development policies such as the Rangeland Household Contract Policy, the Ecological Construction Project, and herder settlement Initiatives have increased integration of pastoral regions into modern markets with promotion of tourism, expanded livestock markets, and marketing opportunities for rangeland resources. Although allocating common rangelands to households is the foundation of current rangeland management strategies to achieve these goals, it removes important technologies for coping with high variability in rangeland forage production from the traditional rangeland management portfolio on the Tibetan Plateau. These include shared risk, shared labor, seasonal and yearly herd mobility, and access to diverse areas of rangelands and multiple water sources. Field study of two villages in Guinan County of Qinghai Province, and Ruoergai County of Sichuan Province from 2011 to 2014 found that the villages responded to externally driven policy, economic, and climate changes with an innovative locally adapted quota-based grazing management system that preserves valuable management technologies, conserves rangeland resources, and provides individual opportunities for financial gain. In this way the village social-ecological system has exhibited considerable resiliency, maintaining a form of community governance that functions to manage the rangelands, improve well-being as indicated by livestock productivity, and, according to local perceptions, maintain rangeland condition. The community-based grazing quota system devised by the villages occupies a middle ground between common and individual models for resource use because it focuses more on how to equitably distribute services and utilities from rangelands, instead of how to distribute rangelands.

Zhuang MH, Gongbuzeren, Li WJ. Greenhouse gas emission of pastoralism is lower than combined extensive/intensive livestock husbandry: A case study on the Qinghai-Tibet Plateau of China. JOURNAL OF CLEANER PRODUCTION [Internet]. 2017;147:514-522. 访问链接Abstract
The increasing demand of livestock products and production efficiency of livestock husbandry, and restoration of grassland ecosystem have been inducing the rapid transition of livestock husbandry systems from pastoralism into intensive systems. Such transition has been resulted in changes in the greenhouse gas (GHG) emissions, though it is rarely studied, especially in the pastoral area of China. Aimed to address this question, on the Qinghai-Tibet Plateau we selected Chanaihai village as the pastoralism system, and Guinan Grassland Development Limited Company as the combination of extensive and intensive livestock husbandry system, to compare the GHG emission between the two systems using life cycle assessment method. Our results showed that the GHG emission intensity both in per unit of area and per unit of carcass weight in the combined extensive/intensive livestock husbandry were higher than the pastoralism, indicating that the shift into the combined extensive/intensive livestock husbandry system increased the GHG emission. Such results could be attributed to the lower soil carbon uptake and higher GHG emission derived from the external inputs such as seed, diesel, and electricity in the combined extensive/intensive system. These findings demonstrated that the ongoing transition in the pastoral area of Qinghai-Tibet Plateau may be inappropriate Under the background of global GHG mitigation. As suggestions, we argued that reduction in the manure combustion and increase in soil carbon uptake could be effective measures to reduce the GHG emission intensity of livestock husbandry.

李文军, 范明明. 生态补偿理论研究进展及争论——基于生态与社会关系的思考. 中国人口资源与环境 [Internet]. 2017:130-137. 访问链接Abstract
生态补偿的概念自提出便受到学界和政府决策者的广泛关注,并迅速成为近20年来生态保护的主要政策手段。虽然基于生态补偿的政策手段被大范围使用,但是生态补偿的相关理论却处于发展与争论的阶段,该理论的适用性及对现实问题的剖析在实践过程中备受质疑。本文梳理了生态补偿理论发展及构建的过程,将其总结为生态系统服务概念的提出、生态系统服务价值评估方法的建立、以及生态系统服务市场机制的构建三个主要阶段。已有研究更多集中在生态补偿的具体实施层面,如补偿标准、补偿方式、效果评估等方面,但是对基础理论探讨不足。本文从生态补偿理论发展及构建的三个过程,综述了目前对生态补偿理论的讨论及争议,认为在处理'社会—生态'关系的核心问题上,尤其在一些长期依赖并利用自然资源的传统地区或者民族地区,目前学术界和政策决策者均对此问题缺乏深入的理解,这也是实践中生态补偿政策未达到理想效果的主要原因之一。最后,本文提出用'社会生态系统服务'一词代替目前所使用的'生态系统服务',这一概念有助于在理论上避免忽视社会系统及社会与生态系统二者之间的关系,减少不当外部政策干预。

通过在青海省海南藏族自治州贵南县的案例研究, 采用半结构式访谈、问卷调查、实地采样以及多相关利益方调查相结合的方法, 以“草–畜–人”完整的社会生态系统视角,从“土壤–草界面、草–畜界面、草–畜–人界面”逐层递进的角度, 充分识别并分析各类草原生态系统服务功能, 并以货币化的方式对天然草原生态系统服务功能进行价值评估。结果表明: 案例地的天然草原生态系统服务功能价值是现有政府统计价值的20倍, 天然草原生态系统的生态价值、提供牧民物质资料的生计价值以及社会价值是比牲畜交易的商品价值更为重要的部分, 也是传统的政府经济统计体系所忽略的部分。即使只限于畜牧业的价值, 案例地天然畜牧业的价值仍为政府统计牲畜价值的1.6倍。因此, 在国家推进绿色经济核算体系的背景下, 政府应改善其原有的统计体系, 更好地反映天然草原生态系统的价值, 并作为草原生态补偿核算的重要依据。

Abstract Beginning in the early 1990’s, grazing lands once held in common were contracted to individual households in the rangeland regions of China. The resulting fragmentation of rangelands has led to ecological and social problems. As China seeks to address intractable poverty and rangeland degradation, attention has turned to rental, or transfer, of contracted grazing land as a market-based approach to re-aggregating grazing land into larger units that support economies of scale. However, given that many pastoral regions still maintain community customary institutions, what the relationship between market mechanisms and local customary institutions should be in rangeland management needs further analysis. This paper applies comparative case studies of two types of relationships between market mechanisms and customary institutions: (1) market mechanisms that replace customary institutions in the case of Axi village, and (2) market mechanisms that are embedded within customary institutions in Xiareer village. This allows contrast of the impacts of differing approaches on livelihoods, livestock production, and wealth differentiation among pastoral households. We found that there is a higher level of livestock mortality, lower livestock productivity, and higher livestock production cost in Axi Village compared to Xiareer Village. In addition, household asset levels are higher and there is less income differentiation in Xiareer Village. It is concluded that embedding market mechanisms within customary institutions has had notable benefits for the herders of Xiareer Village, because it is a better fit to the coupled pastoral social-ecological system. Based on these findings, we argue that in pastoral communities where the rangeland transfer system for contracted grazing land has not yet been implemented, it is critical to reconsider China’s current policy approach to pay greater attention to the innovative management systems being developed in local regions. Instead of considering market-based approaches as oppositional to traditional institutions, options that derive from the interaction of market-based and customary institutions should be considered.

近年来,政府大力推动在完善承包到户基础上的草场经营权的流转,目的之一是通过市场手段来整合牧户个体的草场资源,促进畜牧业的规模化生产。市场机制与牧区传统管理草场的习俗制度,二者的关系及其对草场管理的影响是怎样的?论文选择位于青海省贵南县的元义村和查乃核村为案例地来研究上述问题。元义村反映市场机制取代习俗制度,查乃核村则反映了市场机制嵌套在习俗制度中。通过比较两个案例地的牧户生计、畜牧业生产以及贫富差距,研究发现:1)查乃核村的牧户年均畜牧业资产高于元义村;2)查乃核村的畜牧业生产量逐年增加、牲畜死亡率明显减少,畜牧业生产收益率高于元义村;3)查乃核村的贫富差距明显低于元义村。基于此,论文认为市场机制嵌套在社区习俗制度的制度安排在草场管理中更有效,因为这样的管理模式在满足牧户个体对于权属明晰和补偿需求的同时,能够维持社区共用草场以适应青藏高原多变的气候特征所导致的资源时空分布的异质性。随着市场化的发展,草场管理需要权属明晰及市场机制,但实现这样的目标不需要弱化甚至取代已有的社区习俗制度。

论文基于四川省若尔盖牧区两个村落的田野调查,通过草地资源使用的效率和公平性指标,比较草场使用权全村共有和牧户私有这两种产权制度下的经济与社会效益。研究表明,在青藏高原牧区,草场使用权全村共有较牧户私有在资源使用的效率与公平性两个方面均能获得更好的表现。这是因为全村共有的使用权制度更契合当地的自然与社会实情,这包括草地资源时空差异大的自然条件、藏传佛教浸润下的文化氛围以及较强的社区自组织管理能力的社会背景。因此,建议我国在制定与推行草场使用权制度时,应考虑制度实施地的自然环境与社会文化等各方面背景因素,不能简单地在所有牧区强行推进一种产权制度。

Fan M, Li W, Wei G, Luo F. Tourism Impacts on Indigenous Pastoral Communities in China. Rangeland Ecology & Management [Internet]. 2015;68:86 - 91. 访问链接Abstract
Abstract In China, booming tourism is considered to be a win-win solution to fight both ecosystem degradation and poverty in pastoral areas. However, whether this alternative livelihood can reduce pressure on rangeland and improve livelihood of indigenous peoples has not yet been explored. To examine tourism’s impacts on pastoral communities, we conducted field surveys at Inner Mongolia and Xinjiang and distributed questionnaires in 12 provinces including most of the grassland areas of China. On the basis of fieldwork and national survey data, we found that different types of operations have different impacts on livelihood and ecosystem in pastoral area. Pastoralists involved in tourism can increase the income of pastoral households during the summer tourism season, but that pastoralism still provides the main guarantee of a sustainable livelihood. However, along with the development of tourism, business enterprises from outside the pastoral area may replace local herders in tourism operations. As a result, a large area of rangeland may be lost to local herders, who only receive money if they rent their pastures or serve as laborers; unfortunately, many residents lack the training to perform better-paid roles. In addition, we found that pure tourism that replaces pastoralism does not necessarily protect the rangeland, as it brings a variety of environmental impacts and disrupts traditional use that the rangeland may be adapted to. On the basis of our findings, we recommend that tourism managed by local operators who also engage in pastoralism should become the main direction for economic development.

Abstract Modernization has been regarded as the best way to solve ecological and poverty problems in many arid and semi-arid areas around the world, but is inevitably accompanied by changes in land-use patterns that can lead to new socio-ecological feedbacks. How people and ecosystems of an area respond to such feedbacks determines whether the changes sustainable or not. In this paper, we describe resettlement of nomadic pastoralists in Alxa Left Banner of western Inner Mongolia. We identified the dominant biophysical limiting factor in this region (water resources), and used amount and efficiency of water use as indicators of the ecological impacts of pastoralism before and after resettlement. We also conducted semi-structured interviews with households to collect information about household income, expenditures, and agricultural production risks caused by water shortages to analyze the impacts of resettlement on their livelihood. We found that resettlement greatly increased the usage of water resources, reduced the efficiency of water use, and exacerbated regional water shortages. Although household income increased after settlement, subsistence costs also increased because water shortages increased production costs and risks. Our results suggest that in this arid grassland area of China, ecological resettlement policy is ecologically and economically unsustainable, and may exacerbate local ecological and social problems.
Gongbuzeren, Li YB, Li W. China's Rangeland Management Policy Debates: What Have We Learned?. Rangeland Ecology & Management. 2015;68:305-314.Abstract
In China, three major rangeland management policies have caused dramatic social, economic, and ecological changes for pastoral regions in the past 30 yr: the Rangeland Household Contract Policy (RHCP), Rangeland Ecological Construction Projects (RECPs), and the Nomad Settlement Policy (NSP). The impacts of these policies are greatly debated. In this paper, we conduct a systematic review of academic perspectives on the impacts of the three policies and the causes of ineffective and negative effects. The findings demonstrate that academics increasingly report negative impacts of RHCP on the ecosystem, animal husbandry, pastoralist livelihoods, and pastoral society. An increasing number of scholars, although not the majority, attribute the negative impacts to improper policy itself rather than incomplete implementation. Regarding the RECPs, most academics believe that policies have improved the rangeland ecosystem but with obvious negative impacts on pastoralist livelihoods and pastoral society; they attribute the problems to incomplete policy implementation. For the NSP, most academics report positive impacts on pastoralist livelihoods and animal husbandry, although recent researchers have identified negative impacts on pastoral society and the ecosystem. Although they are not in the mainstream, more and more academics attribute the negative impacts to improper policy. Finally, we apply the concept of coupled social-ecological systems (SES) to further analyze the outcomes of these three policies and propose a more flexible and inclusive land tenure policy that recognizes the diverse local institutional arrangements; an integrated RECP framework that considers coadaptation between social and ecological systems; and facilitating voluntary choice in nomad settlement and developing innovative approaches to provide social services for pastoralists who would like to remain in pastoral areas. As these three policy approaches are applied in rangeland management and pastoral development worldwide, this paper may provide useful implications for future policy development in pastoral regions on a global scale.

城镇化是本届政府提出的主要发展战略之一,然而与农区城镇化关注的焦点不同,牧区城镇化有其自身的特殊性。牧区城镇化的资源制约因素主要是水资源,而非土地;中国牧区处于干旱和高寒的气候带,工业发展受到制约,畜牧业以外的就业机会很少;目前牧区的城镇化大多不是市场发育的结果,而是生态建设项目推动下的政府行为。由于替代生计有限,形成了中青年牧民留在草场继续从事畜牧业,而老人和小孩迁居于城镇的情形。
Li YB, Fan MM, Li WJ. Application of payment for ecosystem services in China's rangeland conservation initiatives: a social-ecological system perspective. RANGELAND JOURNAL. 2015;37:285-296.Abstract
The Chinese government has adopted Payment for Ecosystem Services (PES) as a main approach for preventing or restoring rangelands perceived as undergoing degradation on a massive scale. Using the PES project, known as the 'retire livestock, restore rangeland' project in Alxa of Inner Mongolia as an example, the long-term ecological consequences of such projects is assessed, and the causes of the associated problems from the perspective of social-ecological system explored. Study findings demonstrate that PES, as used in the case study area, is unlikely to achieve the expected outcome of rangeland restoration in the long term. The root cause of such failure is that the PES approach focuses on end-point ecosystem services (outputs), while at the same time decoupling the feedbacks among social and ecological systems that are the key to generating such services. This drives the overall social-ecological system into an undesirable basin of attraction. It is concluded that a PES program for pastoral systems should aim to improve resilience of such a coupled social-ecological system to external shocks and changes, instead of simply maintaining ecological services without considering the origins of such services in the inter-relationship of humans and environment. It is argued that 'Payment for Ecosystem Services' should be displaced by 'Payment for Social-ecological System Resilience' in future policy discussions.;The Chinese government has adopted Payment for Ecosystem Services (PES) as a main approach for preventing or restoring rangelands perceived as undergoing degradation on a massive scale.

为更加全面准确地分析禁牧政策对于草场的恢复效果,采用MODIS卫星提供的遥感影像解译合成植被归一化指数(NDVI)数据,通过对新巴尔虎右旗156户禁牧与非禁牧草场连续8年的数据进行差异性检验,分析在控制降水气温因素的情况下禁牧对草场生物量的影响。同时通过对研究样地牧民的入户访谈调查,分析牧民对于禁牧效果的感知作为补充。研究表明,虽然禁牧草场与自由放牧草场的生物量在禁牧前后出现差异,使得草场状况在一定程度上有所恢复,但相较于当前的退化水平,由禁牧带来的植被恢复对于草场的整体状况改善并不能起到决定性的作用。同时,并非禁牧时间越长草场恢复得越好,禁牧后4年中的遥感影像分析表明,草场的生物量呈现年际波动的特征。而禁牧时间过长,由于打破了原有草地生态系统中“草-畜”的关联关系,反而有可能不利于草场的健康恢复。

李文军 李艳波. 草畜平衡制度为何难以实现“草畜平衡”. 中国农业大学学报:社会科学版. 2012;29:124-131.Abstract
草畜平衡制度是我国草原管理和生态保护的基本制度,但在实施中却难以达到"草畜平衡"的目的。文章基于内蒙古地区的田野调查和文献资料,从草场生态过程和牧民行为两个方面,分析了草畜平衡制度在实施中问题产生的根源。研究表明:一方面,干旱半干旱草场存在一定的非平衡生态系统特征,承载力管理不一定能实现草场的可持续利用;另一方面,牧民对载畜量的控制是一个多因素影响下的综合决策,并受到市场、畜牧业生产周期、生计需求的限制。而现行的草畜平衡制度在这两个基本环节的处理上采取了简单化、标准化的思路,导致该制度不能有效执行。文章认为,在资源时空异质性异常显著的干旱半干旱草场,目前将"草畜平衡"作为落实到每一微观牧户的实施手段,其可行性值得商榷,草场管理中更应该侧重生态系统的弹性管理,而不仅仅是关注作为阈值的承载力本身。

通过在内蒙古克什克腾旗牧区的案例研究,采用参与式观察、半结构式访谈、问卷调查以及多相关利益方调查相结合的方法,描述牧民对于气候变化的感知并辅以气象数据分析,记录其感知下的应对行为,探讨影响其适应能力的因素。研究结果表明:对气候变化,牧民的感知主要为自2000年起干旱加剧,具体表现是降水减少和气温升高以及云、风、雾等气象变化。在气温、降水和气象灾害方面,牧民的感知与气象数据以及统计资料一致。由于牧民更关注气候变化对于生态以及畜牧业产生的影响,除降水量外,他们还关注降水的频率和空间异质性,降水量的年际波动和累积效应以及气温和降水的综合影响。对于干旱加剧导致的地表水减少和天然牧草产草量下降,牧民采取的应对行为包括恢复牧户和牲畜的移动、加强资源使用的排他性和从外界购买饲草料。气候变化下牧民能够采取上述应对行动并有一定作用。当地放牧场的共有产权安排形式、有效的自下而上的监督和自上而下的制裁以及外界力量如政府项目、市场和信贷的支持起到关键作用。
