生态补偿对农户生计的影响——以甘南黄河水源补给区为例

生态补偿项目对农户生计的影响关系到项目可持续性及社会公平性,近年来已成为生态补偿领域的研究热点。本文通过调查退牧还草工程前后甘南黄河水源补给区农户生计资本及生计方式的变化,分析了生态补偿项目对农户生计的影响,提出应建立多样化、差别化的补偿方式,提高项目区农户的生计能力,确保生计安全。研究发现:①生态补偿后农户生计总资本显著增加,除自然资本下降外,其余各类生计资本均增加,但纯牧区、半农半牧区、农区农户的生计资本变幅不同;②生态补偿后农户生计方式发生显著变化,从事非农活动的农户比例增加,生计多样化指数增加,其中农区农户的非农化程度及生计多样化指数的增幅均高于纯牧区与半农半牧区。     

高寒生态脆弱区农户的气候变化适应策略——以甘南高原为例

气候变化对生态脆弱区以自然资源为生计基础的农户产生了严重影响,急需寻求有效的适应策略。以地处青藏高原东缘的甘南高原为研究区,基于1963-2013年气象数据分析甘南高原气候变化趋势,采用入户调查数据分析了气候变化对农户生计的影响及农户采取的适应策略,并利用多元线性回归模型和多项logistic回归模型分析了影响农户适应策略选择的因素。结果显示：① 近50年甘南高原气温呈增加趋势,倾向率为0.23 ℃/10 a,降水呈减少趋势,倾向率为-5.21 mm/10a,63.45%的农户认为气候变化对其生计带来了严重影响;② 甘南高原农户的适应策略多样化指数为2.65,农户的人力资本、自然资本、金融资本及其对气候变化的严重性感知、适应效能感知及自我效能感知与适应策略多样化程度呈显著正相关;③ 甘南高原65.30%的农户采取各种组合型策略应对气候变化,尤以采取扩张+调整型组合策略的农户为多,农户的人力资本是影响其适应策略选择的最显著因素,社会资本与气候变化风险感知的影响次之,金融资本及气候变化适应效能感知的影响最弱。最后,提出提高农户适应气候变化能力的对策建议。     

中国地理学中的甘南研究

区域研究是地理学的核心领域,开展区域研究需要选择既具全球意义又具区域特色,且符合国家重大战略需求的关键区域。作为“第三极”的重要组成部分,地处青藏高原东北缘的甘南高原不仅是典型的地理过渡区与生态脆弱区,也是重要的生态功能区与深度贫困区,因而成为中国地理学开展区域研究的最佳实验区之一。在阐述甘南高原地理学研究价值的基础上,从陆地地表过程与机理、土地利用/覆被变化、农户对气候变化的感知及适应、生态系统服务与生态补偿机制、农户生计及其对生态环境的影响、社会资本与区域发展、城镇化与乡村聚落、旅游发展等领域出发,系统梳理了中国地理学中的甘南研究现状,提出新时期应以更综合的多维视角开展甘南研究,重点关注甘南高原地表格局-过程集成研究、人地耦合系统演化与区域可持续发展、生态系统服务与生态补偿、可持续生计、新型城镇化、乡村发展等关键问题。     

生计风险及其对重点生态功能区农户生活满意度的影响

基于甘南黄河水源补给区入户调查数据,在分析农户生计风险及生活满意度特征的基础上,探明生计风险对农户生活满意度的影响。结果发现：① 甘南黄河水源补给区农户面临的主要生计风险为自然灾害、家人患病和子女学费开支,其对农户的冲击最为严重且持续时间较长;② 农户大多遭受多重风险的冲击,其生计风险多样化指数为4.12,面临家人患病与自然灾害、家人患病与子女学费开支、家人患病与建房开支等风险组合冲击的家庭较多;③ 农户的生活满意度处于中等水平,且经济示范区高于重点保护区和恢复治理区;④ 农户生活满意度除受子女学费开支、草场/耕地质量下降、人畜饮水困难、家人去世开支、生态政策等风险的严重程度和持续时间、家人患病风险的持续时间以及金融资本、自然资本、社会资本、心理资本、生计方式多样化程度的影响外,受家人患病与子女学费开支、自然灾害与子女就业困难及生计风险的综合严重性程度与综合持续性程度交互作用的影响更加显著。最后,提出防范生计风险、提高生活满意度的政策建议。     

农户生计资本与生计策略关系的实证分析——以河西走廊沙化土地封禁保护区外围为例

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。

“阿者科计划”对农户生计的影响分析——基于DFID可持续生计框架

农户生计状况是实现乡村振兴和乡村可持续发展过程中需要关注的重点。文章以阿者科村为案例地,通过笔者亲身驻村经历和入户调查获取数据,基于DFID可持续生计框架构建了农户生计资本评价指标体系,详细分析了“阿者科计划”这种结构与制度因素的转变对当地农户生计的影响,并探讨了其中的影响机制。研究发现：1）乡村旅游发展使农户参与其中,成为村集体公司员工或自主开展旅游经营,旅游与传统的生计方式共同构成了了农户多样化的生计组合;2）农户生计策略出现转型和分化,形成了旅游主导型、旅游务工型、参与旅游型、务工主导型和半工半农型5种类型农户;3）不同类型农户的生计水平和各生计资本组合形式存在差异,其中生计资本总量由高到低依次为旅游主导型、旅游务工型、参与旅游型、务工主导型、半工半农型;4）“阿者科计划”形成了在政府和高校支持下,农户内生动力充分发展的长效机制,旅游成为农户传统生计的重要补充,提升了其生计资本。

不同生计方式农户的环境影响——以甘南高原为例

生计方式是影响生态环境的重要人文因素。利用参与式农村评估方法,从生活用能与生态足迹出发,研究了甘南高原不同生计方式农户的环境影响。结果发现:①随着非农化水平的提高,农户生活用能总量下降,其中生物质能比重降低,而商品性能源比重增加;②随着非农化水平的提高,农户的人均生态足迹下降,农户对草地资源的依赖程度降低,但对林地、建筑用地、水域、化石能源用地的依赖程度增强;③提高非农化水平及农户受教育程度将减缓对生态环境的影响,而扩大家庭规模、提高富裕水平具有加剧环境影响的作用,但是现有样本数据支持环境Kuznets曲线假说。     

甘南牧区劳动力转移背景下留守农户生计策略选择

劳动力转移的行为和经历对贫困农（牧）户的生计产生了并继续产生着复杂而深远的影响,并构成了留守家庭成员进行新的生计选择的背景和前提条件。在资本变动和要素约束下,西部民族地区农（牧）户进行着不同的生产决策,并形成不同类型的生计策略。以甘南牧区为例,通过解析劳动力转移的特征变量,总结典型的劳动力转移农（牧）户家庭主要的生计策略模式,揭示了甘南牧区劳动力转移对留守农（牧）户生计策略选择的作用关系,并得出相应的结论。结果表明：转移劳动力文化水平、劳动力转移的外出时间、务工去向与转移劳动力工种类型在一定程度上影响了留守农（牧）户生计策略的选择。这可为西部民族地区政府部门制定科学、合理、可持续的劳动力资源利用政策,促进当地农（牧）户生计的可持续发展提供参考依据。     

Livelihood diversification of farmers and nomads of eastern transect in Tibetan Plateau

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.

青藏高原东部样带农牧民生计的多样化

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.

青藏高原东部山地农牧区生计与耕地利用模式

利用分层随机抽样、参与式农村评估及其工具、地块调查、数理统计等方法,对63个农户、272个地块进行了系统的调查与取样,研究了青藏高原东部山地农牧区金川县克尔马村的生计多样化与耕地利用模式。结果表明:①不同类型农户的生计策略选择、组合及收入不同,生计多样化,引入并扩大非农活动是当地生计策略的发展趋势,但不利的自然环境和社会经济条件以及农户自身素质共同影响了生计和土地利用的可持续性;②各种生计策略对土地利用的影响不同,主要影响土地利用类型和土地利用集约化水平;③以非农活动为主的生计多样化可能是该区构建可持续生计的核心,同时也是实现土地可持续利用的根本途径。     

青藏高原东部山地农牧区生计与耕地利用模式

This study examined livelihood diversification and cropland use pattern in Keerma village, located in Jinchuan County, eastern Tibetan Plateau. Through stratified random sampling survey, participatory rural appraisal, investigation of households＇ plots and statistical methods, 63 households and 272 cropland plots were systemically investigated and sampled. The results show： （1） Different types of household have variety livelihood strategies, portfolio and income. Livelihood diversification and introducing and expanding off-farm activities can be the future trend, whereas, adverse natural environment, socio-economic conditions and peasants＇ capabilities together affect sustainable livelihood and land use. （2） Each livelihood strategy has its own impact on land use, mainly affecting land use type and land use intensi- fication level. （3） Diversification into off-farm activities could be the key of building sustainable livelihood and the essential approach of realizing sustainable land use in the region.     

‘Prosperity beyond belief’: The interaction between a potato crop boom,vulnerability and volcanic hazard in Central Java,Indonesia

This article examines the interaction between conditions of vulnerability and a potato crop boom in Central Java's highlands. While partaking in agricultural endeavours on volcanic slopes can bring substantial economic rewards, the local benefits associated with these livelihood activities are often overlooked by disaster scholarship. Drawing on a period of fieldwork conducted in the Dieng Plateau, a region characterized by a series of craters that periodically erupt mud and poisonous gas, this article demonstrates how a potato crop boom has evolved despite, and in part because of, the underlying volcanic hazard. By integrating the sustainable livelihood and agrarian change literatures, the article concludes that the potato boom has provided significant economic opportunity, and through this, a means to reduce vulnerability. Yet, despite these economic gains, the agrarian shift described herein has also introduced new vulnerabilities as farmers have become dependent on a resource intensive crop. These findings demonstrate how theories of agrarian transformation can complement livelihood perspectives in disaster research, and provide greater detail into the local and regional processes that encourage people to often-profitably farm hazardous land.
