The Influence of Community Size and Location on Different Dimensions of Vulnerability: a case study of Australian coastal communities     

Ingrid van Putten  Cecilia Villanueva  Christopher Cvitanovic 《The Australian geographer》2017,48(1):121-142

ABSTRACT

Coastal communities are part of the Australian identity but little is known about their characteristics and their long-term prosperity prospects. Increased migration to coastal areas and increased exposure to extreme climatic events indicates a need for social and economic data to inform socio-ecological systems planning. Here, we undertake a geo-spatial analysis to develop a typology of Australian coastal communities and assess relative vulnerability to climate-driven environmental change for a range of social and economic indicators. The aim of this study is to understand how the vulnerability of Australian coastal communities varies with geographic location or community size, and in comparison to other community types. Results show that both the population size and location of a coastal community matter and that coastal communities overall are more vulnerable on some socio-economic dimensions to climate-driven environmental change than their rural equivalents. However, results also demonstrate that the smallest coastal communities are strong in some important aspects of the human, social and financial domains, putting them in a good position to deal with some changes. Scale-appropriate and context-specific social policies are needed to address identified socio-economic vulnerabilities, supported by a range of formal and informal institutional structures, such as strategies to improve education and female workforce participation, and encourage participation in volunteering to increase human and social capital.  相似文献   

甘南牧区劳动力转移背景下留守农户生计策略选择          下载免费PDF全文

苏芳  郑亚萍 《干旱区地理》2018,41(4):826-832

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。  相似文献   

Combating Desertification and Improving Local Livelihoods through the GGWI in the Sahel Region: The Example of Senegal     

Salif Diop  Aliou Guisse  Claude Sene  Birane Cisse  Ndeye Rokhaya Diop  Sokhna Di  Ka  Amady Gnagna Cisse  Saly Sambou  Ousmane Ndiaye  Adand  Belarmain Fandohan  FU Chao  WANG Guoqin  WANG Yongdong 《资源与生态学报(英文版)》2018,9(3):257-265

The Great Green Wall Initiative (GGWI) has an overall objective of fighting desert encroachment through proven practices of sustainable management of land, and the reinforcement and protection of natural resources and systems of production and transformation, while also ensuring socio-economic development of local communities through multi-purpose activity platforms. The activities described in the present study are designed to accomplish several goals: (1) generate wealth, (2) strengthen access to basic social services, (3) manage the transition to a green economy as a means of creating suitable conditions for the emergence of rural production centers, (4) integrate sustainable development in order to eradicate poverty and food insecurity, and (5) strengthen adaptation and resilience capacities of local populations. The present study was undertaken on the basis of a wide variety of available publications and documentation, including articles and scientific papers, thesis, meeting summaries and reports, concerning the implementation of the Great Green Wall Initiative/GGWI in Senegal.  相似文献   

Empirical calibration of climate policy using corporate solvency: a case study of the UK’s carbon price support     

Ben Caldecott  Gerard Dericks 《Climate Policy》2018,18(6):766-780

Emission reductions improve the chances that dangerous anthropogenic climate change will be averted, but could also cause some firms financial distress. Corporate failures, especially if they are unnecessary, add to the social cost of abatement. Social value can be permanently destroyed by the dissolution of organizational capital, deadweight losses paid to liquidators, and unemployment. This article proposes using measures of corporate solvency as an objective tool for policy makers to calibrate the optimal stringency of climate change policies, so that they can deliver the least loss of corporate solvency for a given level of emission reductions. They could also be used to determine the generosity of any compensation to address losses to corporate solvency. We demonstrate this approach using a case study of the UK’s Carbon Price Support (a carbon tax).

Key policy insights

• Solvency metrics could be used to empirically calibrate the optimal stringency of climate policies.

• An idealized solvency trajectory for firms affected by climate change policy would cause corporate solvency to initially decline – approaching but not exceeding ‘distressed’ levels – and then gradually improve to a new ‘steady state’ once the low-carbon transition had been achieved.

• In terms of the UK’s Carbon Price Support, corporate solvency of energy-intensive industries was found to be stable subsequent to its introduction. Therefore, the available evidence does not support its later weakening.

Socio-economic vulnerability due to climate change: Deriving indicators for fishing communities in Mumbai     

《Marine Policy》2017

This paper assessed the socio-economic implications of climate change and vulnerability of fishing communities known as “Koli” living in Mumbai, India. The vulnerability indicators are derived from sustainable livelihood literature and use of multi-criteria analyses and are validated with expert opinions. A survey of two hundred fishermen from five fishing villages in Mumbai was conducted to collect data. The results demonstrate that vulnerability perpetuates due to physical and financial resource constraints among the fishing community. Fishermen from Madh and Worli villages are observed to be more vulnerable and less adaptive due to their inability to use efficient mechanized boats and advanced fishing implements, such as fish finders and GPS (Global Positioning System). The divergence in the vulnerability scores among fishing villages is attributed to the coping strategies, resource availability, knowledge and the benefit derived from the local government. Fishermen have been observing the negative impacts of climate change on their fishing livelihoods. Adaptation strategies to maximize fish catch are observed in such practices as targeting different species and fishing intensively for several days. However, these practices are leading to an imbalance in the common resource pool and biased resource sharing among different groups of fishermen.  相似文献

Analyzing land-use change in farming-pastoral transitional region using autologistic model and household survey approach     

Likai Zhu  Jijun Meng  Xiyan Mao 《中国地理科学(英文版)》2013,23(6):716-728

Land change science （LCS） strives to understand and model land-use change, which will further advance the understanding of multiple issues in the socio-ecological systems. Based on GIS/RS techniques, autologistic model, and household survey method, this study investigated major land use changes and their causes from 1978 to 2008 in Uxin Banner （county-level）, Inner Mongolia in China and then developed an understanding of the relationships between household livelihood and land-use pattern. Results showed that cultivated land increased from 1988 to 2000, and leveled offafter 2000. Built-up land increased stably for the period 1978 2008. The change of grassland and bare land differed among the three periods. From 1978 to 1988, grassland increased by 23.3%, and bare land decreased by 20.48%. From 1988 to 2000, bare land expanded by 1.7%, but grassland declined by 1.3%. From 2000 to 2008, an increase in grassland area by 1.8% was observed, but a decrease in bare land area by 9.0% was witnessed. The autologistic models performed better than logistic models as indicated by lower Akaike Information Criterion （AIC） values. Factors associated with human activities significantly correlated with the change of cultivated land, forest land, grassland, and built-up land. The produce prices and extensive cultivated land use are major issues in the farming area. This study suggests that completing land circulation systems and maintaining the stability of price are effective solutions. By contrast, reclamation and overgrazing are major concerns in the pastoral areas. Implementing environmental policies effectively, transferring population out of rural pastoral areas, and developing modem animal husbandry are effective ways to address these issues.  相似文献
