集体林权改革后农户生计变化实证分析——以福建省永安县为例     

周文涛 《安徽农业科学》2013,(28):11399-11402

以福建三明市永安县为例,分析了集体林权改革之后农户生计的变化。结果发现,农业生计策略从以农业生产为主、重点利用自然资本和人力资本的生计策略逐步向以金融资本的积累、使用和转化为主,综合利用五大资本的更为开放的新的生计策略转变。  相似文献

气候变化感知对农户生计策略的影响——基于云南省农村居民调查数据     

段存儒  武照亮  曾贤刚 《中国农业大学学报》2023,28(7):251-264

为理清气候变化感知影响农户生计的基本路径和内在逻辑,本研究基于云南省昭通市大山包镇农户调查数据,应用偏最小二乘结构方程模型分析气候变化感知对其生计策略的影响。结果表明：1)气候变化感知对农业生计策略具有显著负面影响,但对非农业策略呈现显著正向影响;2)气候变化感知同时通过适应性行为这一中介变量间接影响生计策略,进一步推动农业生计策略向非农化方向发展;3)气候变化感知对生计策略的影响路径表现出明显的农户个人因素差异和农业生产环境差异,风险喜好型和信息获取能力较强的农户群体更倾向于调整和转变生计策略,存在农业补贴和农业基础设施较完备时农户倾向于坚持农业生计策略。本研究能够为政府制定针对性更强的气候变化政策、提升农户可持续生计能力提供一定参考。  相似文献   

基于多项Logit模型的牧户生计资本对生计策略选择影响的实证研究     

丁文强  侯向阳 《中国农学通报》2020,36(9):150-158

为探究牧户生计资本对生计策略影响,识别牧户生计策略转化的关键生计资本和生计资本指标,以便引导牧民调整生计结构,提高草原治理能力。以内蒙古自治区5种草原类型15个旗（县）848户牧户为样本,运用熵值法评估牧户生计资本,建立多项Logit回归模型,识别影响牧户生计策略转化的关键生计资本。研究区牧户生计资本值为1.428;4类生计策略牧户生计资本存量为纯牧性>牧兼性>兼牧性>非牧性,P< 0.01;5种草原类型牧户生计资本存量为草甸草原>典型草原>荒漠草原>沙地草原>草原化荒漠,P<0.01。牧户以牧业收入和政府转移收入为主,纯牧性生计策略为首选的策略;金融资本存量是影响生计策略转化的关键生计资本,对牧户由纯牧性向牧兼性、兼牧性和非牧性生计策略转化均具有显著负向影响。牧户家庭承包草地资源、使用草地资源和家庭总收入是影响生计策略转化的关键生计资本指标。  相似文献   

Social resilience as a controlling influence on desertification in Senegal     

D. Bradley  A. Grainger 《Land Degradation \u0026amp; Development》2004,15(5):451-470

While ecological resilience may explain why apparent symptoms of desertification are often temporary, social resilience can prevent degradation resulting from overexploitation of land in response to drought and other constraints. This paper describes a Social Resilience Model in which actors switch from performance strategies to survival strategies when the perceived severity of constraints exceeds a critical performance–survival threshold (PST). This is determined in comparison with a reference mode that depends on a learning facility developed by repeated exposure to cycles of constraint, search and feedback. Actors select particular strategies by comparing welfare gains with their aspiration levels—a concept that allows more flexible decision making than profit maximizing or satisficing alone. The model is tested in the silvopastoral zone of Senegal, where desertification is not as widespread as commonly assumed, despite severe constraints. The two major ethnic groups, the Wolof (mainly croppers) and the Peul (mainly pastoralists) anticipate and respond to environmental and socio‐economic constraints differently, and have different performance and survival strategies. The Peul have the higher social resilience, with more flexible decision‐making objectives, greater mobility, a more extensive action space, a learning facility supporting efficient search and feedback processes, a reference mode attuned to high anticipation and recognition of stress, and a high PST. They also exhibit more continuous performance–survival switching than the Wolof, who make a radical change from cropping to labour migration and reliance on external support.

Should I stay or should I go? Fishers’ ability and willingness to adapt to environmental change in Cambodia's Tonle Sap Lake     

Krishna Bahadur KC  Ratha Seng  Evan Fraser 《Fisheries Management and Ecology》2019,26(3):211-223

The livelihoods of people dependent on the Tonle Sap floodplain ecosystem in Cambodia are expected to be affected by changes in economic conditions, social circumstances, environmental perturbations, demographic shifts and political climates. This study assesses how small‐scale fisheries’ livelihoods are changing in response to social and environmental conditions using the opinions of fishers collected through an intensive family survey of 514 households from Pursat and Battambang Provinces in Cambodia. Probit modelling approach was used to assess whether a fisher would continue fishing or not in the future when subjected to a variety of shifting conditions and identify the factors associated with their response. It was found that in any future condition about 50% of fishers would likely continue to fish, which suggests how much they love their traditional livelihood of fishing. The remaining 50% considered to diversify their livelihood strategy by shifting towards a combination of fishing, farming, and off‐farm jobs. Furthermore, the analysis found that the fishers will change their fishing practices depending on how other sectors in the region develop. The model showed increasing access to agricultural activities decreased the likelihood of continuing to fish, whereas finding an off‐farm job corresponded to increased likelihood of continuing to fish.  相似文献

Agrobiodiversity loss and livelihood vulnerability as a consequence of converting from subsistence farming systems to commercial plantation‐dominated systems in Xishuangbanna,Yunnan, China: A household level analysis     

Y. Fu  J. Chen  H. Guo  H. Hu  A. Chen  J. Cui 《Land Degradation \u0026amp; Development》2010,21(3):274-284

Production of rice (Oryza sativa) under a shifting cultivation system (swidden rice) and paddy fields (wet rice) is an important livelihood strategy in Xishuangbanna, Yunnan, China where households are facing conversion from subsistence systems to commercial plantation‐dominated systems represented by smallholder rubber plantations. However, there are few studies of the effects on rice production and varieties diversity, as well as livelihood effects at a household level during this conversion. This paper presents a household level analysis of agrobiodiversity loss and food security, as well as livelihood vulnerability during agroecosystems' conversion in Xishuangbanna. First, a quantitative assessment was made of the statistical data for rice and rubber production during the past 50 years in Xishuangbanna and at a village level from 1985 to 2005 for three villages from the valley floor and upland hills, respectively. Second, at a household level, 60 per cent of households from the three villages were investigated with a questionnaire from 1998 to 2005. The process of transformation has led to significant changes in the household's income and its proportion. Meanwhile, households have suffered livelihood vulnerability from excessive rubber plantations. The centrality of rice in Southeast Asian agricultural and social systems, contrasted with the significant erosion of rice‐based agroecosystem of local households, calls for increased attention to the livelihood vulnerability during this conversion. Correspondingly, practical strategies to resolve livelihood vulnerability are proposed, such as construction of paddy and effective irrigation systems for food security, agroforestry systems in rubber plantation, instead of monoculture, and diversification of sources of household income.

西藏高寒牧区发展设施蔬菜的效应分析          下载免费PDF全文

关志华  王忠红 《农学学报》2012,2(5):67-70

为有效解决西藏高寒牧区牧民吃菜难问题,采用调查与资料分析法,从理论角度提出在西藏高寒牧区牧民安居房周围发展适度规模日光温室进行蔬菜生产的观点。认为其对草场环境的破坏是极其微小的,在技术等方面是可行的;若通过蔬菜销售获得经济收益时将可能改变牧民单一的牧业生产方式,并促进牧民对现代农业生产技术学习的兴趣,进而有可能通过对设施蔬菜生产投入力度的加大,减少家畜养殖数量,最终因载畜量减少而对草场环境保护产生积极的推动作用。  相似文献
