青藏高原东部样带农牧民生计的多样化 总被引：22，自引：2，他引：20
随着草地退化和药材资源减少,青藏高原东部农牧民的生计受到了严重影响.农牧民如何利用生计资产实现生计多样化是该区域可持续发展面临的关键问题.实地调查采用PRA法,结合调查结果调整了生计资产评估指标,从样带尺度定量分析了高原东部高山峡谷区、山原区和高原区农牧民的生计资产现状、生计多样化特点和今后的生计策略.结果表明:①生计多样化是农牧民普遍采用的生计策略.高山峡谷区农牧民生计多样化水平较高,从事二三产业较多,普遍寻求发展型生计.而随着海拔升高,农牧民的生计多样化水平降低,从事的生计活动类型减少,发展型生计的比例也降低;②海拔较低的高山峡谷区和山原区,生计资产总值高,而海拔越高的高原区,生计资产总值较低,主要反映在人力资产和自然资产上;③居民所拥有的生计资产与生计多样化水平高度正相关;④农牧民近期仍基于生计资产改善生计策略;⑤高山峡谷区和山原区农牧民寻求发展型生计为高原区牧民提供了很好的借鉴.建议政府围绕生计多样化的制约因素进行投入,以提高牧民的能力,协助高原区牧民建立发展型生计. 相似文献

Livelihood diversification of farmers and nomads of eastern transect in Tibetan Plateau 总被引：3，自引：2，他引：1
Livelihoods of farmers and nomads in Tibetan Plateau are severely affected by grassland and herbal resources degeneration.
How to help them achieve livelihood diversification is a key sustainable development issue. This paper examines livelihood
assets, livelihood diversification level and livelihood strategies of farmers and nomads in 3 regions of eastern transect
in Tibetan Plateau. The results show that livelihood diversification is a popular strategy. From high mountain gorge region
to mountain plateau region and plateau region, livelihood diversification level is reduced, and livelihood activities and
proportion of extended livelihood also decrease. Livelihood assets and livelihood diversification level decrease with the
increase of elevation, mainly shown in human assets and natural assets. Livelihood diversification level is highly correlative
with livelihood assets, mainly shown in natural assets, human assets and social assets. Livelihood improvement strategies
of farmers and nomads are still based on existing livelihood assets, mainly raising livestock and digging herbs, and less
farmers and nomads consider off-farm employment or doing business. Nomads in plateau region should learn much from experiences
of extended livelihoods of people in high mountain gorge region and mountain plateau region. Therefore, aids of governments
should focus on relieving restricted factors of livelihood diversification and help them improve their abilities to build
up extended type livelihoods. 相似文献

东北地区可持续生计安全时空分异格局及障碍因子诊断 总被引：2，自引：1，他引：1
随着“新东北现象”的出现,东北地区转型与可持续发展问题突显,可持续生计安全亟待提升。以2003~2015年东北地区37个地级市为例,基于可持续生计安全框架构建可持续生计安全评价体系,采用灰色关联TOPSIS模型对东北地区可持续生计安全进行综合测度,并运用空间自相关、地理探测器和障碍度模型等方法探讨其时空格局演变规律、空间分异成因和障碍因素。结果表明：① 东北地区可持续生计安全指数总体偏低,整体上空间分异特征明显,但随时间推移,区域间差异逐渐缩小。② 空间集聚性特征显著,热点区和次热点区分布主要呈现哈长地区和沈大沿线地区两大组团,次冷点区和冷点区呈边缘式分布于内蒙古东部、黑龙江北部、吉林南部等经济落后地区。③ 工业化水平、经济总量、工资收入、二氧化硫排放强度和投资强度等是影响东北地区可持续生计安全的主要因素。④ 资源环境支撑力和经济生产力是制约东北地区可持续生计安全提升的两大短板;空间阻力模式以“经济效率>生态安全>社会公平”类型占主导。最后,提出应将政策与制度因素纳入可持续生计安全框架。 相似文献

Effective agricultural practices can enable and sustain rural livelihoods, particularly in rapidly developing and transforming areas such as the Chinese Loess Plateau. Drawing from the Sustainable Livelihoods Approach (SLA), a conceptual framework for agricultural practices and sustainable rural livelihoods for the Yangou watershed within the Chinese Loess Plateau is presented and discussed. It is found that agricultural practices that include building terraces, returning sloped farmlands to forestland and grassland, and expanding orchards all have had positive and significant impacts on farmers' livelihood assets, strategies, outcomes, and vulnerabilities. From 1997 to 2006, 48.4 ha (95%) sloped farmland in the Yangou watershed was converted to new land management, and the percentages of income from fruit sale and sale of labor to total income dramatically increased by 59% and 14%, respectively. The watershed community also experienced 159% raise in per capita net income from 1997 to 2003, while the watershed itself experienced a 99% decrease in sediment yield from 1998 to 2007. These positive and significant impacts of new agricultural practices on the sustainable rural livelihoods of the Yangou watershed are evident in the community's reduced dependence upon grain and subsidies income, the diversified strategies for livelihood, and the improved environmental indices. The successful implementation of new agricultural land management practices and policies in the Yangou watershed strongly suggest that similar transformations can be achieved in similar regions throughout China's vast rural areas of the Loess Plateau. 相似文献

黄土高原农户可持续生计评估及未来生计策略——基于陕西延安市和宁夏固原市1076 户农户调查 总被引：5，自引：1，他引：4
农户可持续生计问题是黄土高原自实施生态退耕政策以来备受关注的关键科学问题之一。通过构建可持续生计效益评价模型, 对农户可持续生计效益进行了分级评价, 并分析了不同类型农户的可持续生计效益差异。结果表明:① 具有较高可持续生计效益指数的农户生计收入构成趋向于多元化, 不同生计策略收入所占比重也趋向平均化, 而生计效益指数较低的农户主要依赖于外出打工、卖粮菜等个别生计策略;② 各类型农户的人均生计效益指数和人均年收入排序呈现出:发展果园型>做小生意型>外出打工型>大棚种植型>舍饲养殖型。基于可持续生计效益评价并结合主体功能区战略, 提出4 种黄土高原未来生计策略:① 推进人口城镇化, 有序引导生态脆弱地区人口外迁;② 促进农地流转, 扩大农业生产规模;③ 拓展生计策略, 增强收入来源多样性;④ 加强技术培训, 提高农户非农生计可持续性。 相似文献

从农户可持续生计框架出发,以河西走廊六县为调研对象,建立了农户生计指标体系并对其进行评估,从而揭示了当地农户生计资本与生计策略之间的影响关系。结果表明:(1)无论是项目组还是对照组,农户的5种生计资本整体比较稀缺,其中自然资本和金融资本极度匮乏,而人力资本、社会资本和物质资本相对较丰富,因此农户生计资本单一且配置极不合理,从而导致农户脆弱性程度高。(2)自然资本、人力资本和物质资本对农户生计策略的影响比较显著,其中自然资本和物质资本丰富的农户往往倾向于选择农业生产,而人力资本丰富的农户往往倾向于选择非农产业。(3)经定量评估对照组农户的农业兼业化程度要比项目组农户高。基于此,政府可以采取诸多措施来改善农户的生计现状,从而提升农户的生计水平,进一步转变当地农业的发展模式,缓解生态压力。 相似文献

The Okavango Delta in Botswana hosts abundant wildlife and a human population with diverse livelihoods. Representing a heterogeneous landscape nuanced by spatial and temporal variability, the region has recently seen an expansion of floodwaters with social impacts ranging from livelihood disruption to human displacement. This article reports on in-depth interviews conducted in 2012 regarding these transitions in Mababe, a community in the eastern Okavango Delta, to evaluate how dynamic environmental processes alter perceptions and livelihood responses. We focus on community members’ variable interactions with wildlife in spaces of human–wildlife overlap also experiencing change. While human–wildlife interactions can have negative effects, we find that perpetuating the common narrative of human–wildlife conflict overlooks how disruptions can usher in new relationships between people and animals. In order to move beyond the conflict narrative, we conclude that spatial and temporal context is essential to evaluate effects of dynamic, uneven, and sometimes unpredictable human–wildlife encounters. 相似文献

Farmers’ livelihoods and their impacts on the ecosystem are important indicators of human-land relationships. Appropriate livelihood strategies for farmers can meet the needs of human well-being and promote the sustainable use of natural resources, thereby maintaining the health and stability of natural ecosystems. Scholars have carried out a great deal of research on the changes in farmers’ livelihoods, as well as the driving mechanisms and ecological effects, but there are still many controversial issues about the ecological effects of farmers’ livelihood transformation. On the basis of collecting and sorting out the relevant literature, this paper analyzes the previous research results on the transformation mechanism and ecological effects of farmers’ livelihoods, and further explores the coupling relationship. Through the analysis and summary, we find that the choice of farmers’ livelihoods is affected by natural factors, subjective willingness and social policies. The transformation of farmers’ livelihood changes the ways of production, consumption and resource utilization, which in turn profoundly affects the evolutionary process of the natural ecosystems. This paper establishes a research framework for the livelihood transformation mechanism of farmers and its ecological effect, and finally summarizes two directions that need to be studied further in the future: (1) Exploring the interactions between the driving factors of farmers’ livelihood transformation; and (2) Exploring a win-win sustainable mechanism for farmers’ livelihood needs and natural resource utilization. 相似文献

基于可持续生计框架探究旅游开发对拆迁村民生计的影响。以珠海横琴富祥湾新、旧村因长隆国际海洋度假区开发搬迁村户为调查对象,采用访谈法与问卷调查法,对比分析了村民搬迁前后的生计资本、生计策略、生计结果的变化情况,并研究了生计资产→生计策略→生计后果三者的相互作用关系。研究发现：村民搬迁后生计资本和生计结果有明显改善,影响生计策略和生计结果最重要的生计资本是人力资本,其次是金融资本和社会资本。人力资本存在显著优势的村户更容易获益而具有高可持续生计能力;村户利用社会资本优势也可以维系中等程度的生计水平;那些在度假区就业的村户,普遍缺乏生计资本,其生计可持续性较低。拆迁补偿和提供就业仅是维系村民生计的最后的一道保障,引导人力资本的提高才是关键。这需要政府将针对居民的培训以及就业心理干预工作一并纳入拆迁配套政策之中。 相似文献

As one of the world's most water-abundant countries Nepal has plenty of water, yet resources are unevenly distributed, both spatially and temporally. Limited accessibility and poorly managed water resources continue to inhibit socioeconomic development. Poverty levels are high across the nation (57% of the population lives below the international poverty line) and population expansion, coupled with rapid environmental change, is thought to be placing substantial pressure on water resources; an irrefutable asset for sustaining livelihoods and an essential contributing factor for alleviating poverty. Precipitation is a vital water resource for much of the rural population, 80% of which are dependent on rain-fed agriculture for their livelihoods, and fluctuations in which can give rise to changing states of poverty. Here we provide a comprehensive spatiotemporal analysis of precipitation time-series data for Nepal and discuss the contribution of precipitation change to water resources management for this land-locked Himalayan nation. We show that precipitation totals have predominantly remained stable; precipitation extremes and variability indicate widespread decrease; and no clear variation in monsoon onset date is reported. Based on these results, we suggest that water resources management needs to focus on population and environmental pressures, rather than specifically mitigating for precipitation change. 相似文献

China has achieved a comprehensive victory in poverty eradication. Relocation has been the major measure of the poverty alleviation strategy, and 10 million poor people have successfully been relocated in the ‘Thirteenth Five-Year’ period (from 2016 to 2020). This paper established an integrated evaluation index system for the livelihoods of relocated groups and the sustainability of the village, based on the framework of United Nation 2030 Sustainable Development Goals and using the data from questionnaire surveys in Bailang Village, Tibet. The indicator system quantitatively analyzed the changes in the livelihoods of different agro-pastoralist groups before and after relocation from the three aspects of living standards, livelihood assets, and livelihood strategies. The results showed that relocation led to the improvement of the livelihoods of immigrated households. As the duration after relocation increases, the living standards rise steadily, especially in poverty eradication (SDG1), which increased nearly 100%. Relocation affects the livelihood strategies of the relocated groups, in that the original pure farmers chose more diverse livelihood strategies and the non-farm employment ratio (SDG8) of the village increased. The total SDG score increased from the perspective of the sustainable development of the village. The data also showed that relocation had limited impacts on the livelihoods of the aborigines. The results implied that the relocation policy for poverty alleviation has been implemented successfully in this area. This research could support policy optimization for improving the sustainability of the village and the livelihoods of the immigrants. 相似文献

This paper explores the evolution of land use and natural resource management strategies over the past twenty to fifty years in a remote Sahelian region. The empirical example is Karagou village in SE Niger. Building on an in-depth survey from 1992 and a targeted, follow-up analysis of contemporary land use strategies in 2011, the change process is scrutinized.The analysis uses the conceptual lenses of land systems science, human–environmental timelines, and the notion of multiple exposures. Enabling and constraining conditions for local livelihoods in terms of the resource base (landscape, water, and population) are described. Results characterize how land use strategies have developed and how local people opportunistically use different landscape elements such as dune landscapes, valley bottoms (bas-fonds) and oases (cuvettes). Major concerns are rainfall variability, saturation of cropland, and perceived dwindling groundwater resources. It is concluded that the land use and livelihood strategies have remained remarkably stable in the face of the changing socio-ecological fringe conditions, but that this situation may hamper a sustainable transformation. 相似文献
