Dominique VAN DER MENSBRUGGHE † 《Asian Economic Policy Review》2010,5(1):63-83
This study outlines potential futures for the global economy through the 2050 with a specific focus on the countries of Asia. With underlying assumptions about population and output growth, a baseline scenario assesses the growth of greenhouse gas emissions and the ensuing impacts on the climate. Under the baseline scenario, Asia's high growth leads to a strong rotation in global output and emissions by the year 2050. The analytical framework traces back the changes in temperature to economic damages – limited to the agricultural sectors. Parts of Asia are likely to see much higher dependence on food imports as a consequence of these damages. Various carbon tax scenarios are implemented to assess the potential for reducing carbon emissions. Because of the structure of their economies, Asian countries are likely to bear the greatest burden in reducing emissions in an efficient global tax scheme, but there is significant scope to ease this burden through financial transfers. 相似文献

加拿大大部分地区地处北美寒冷地带,在漫长的冬季,寒冷时间较长,且暴风雪较多,十分恶劣的冰雪天气给加拿大带来了巨大的损失,也使加拿大积累了很多应对严重自然灾害的经验,逐步摸索了很多有效的措施。
本文重点介绍一些加拿大在应对严重自然灾害和突发事件方面的经验和措施,如:通过立法规范重大自然灾害和突发事件的管理工作,建立全社会的防灾减灾责任机制和服务体系,充分做好灾害前准备工作,重视气候变化和防灾减灾领域的研究、加强防灾减灾科研投入,政府的正确引导和全民教育,先进的气候预报预警,全方位的信息服务,有组织的统一行动等,供有关方面参考。 相似文献

随着全球气候变化带来的恶劣影响进一步加剧,减缓和适应气候变化已成为世界各国所关心的重要议题。越来越多的国家采取了各种温室气体减排措施,征收碳税就是其中之一。目前欧盟一些国家已实行碳税,并取得了一定的效果。以芬兰、丹麦、瑞典和英国为例,对这四个国家的碳税情况进行比较分析,以期对中国有所启示。 相似文献

Even though diversified agroforestry systems can provide sustainable livelihoods and a resilient production of different goods, adoption remains limited in Bolivia. We examine major obstacles to agroforestry adoption and possible incentives proposed by farmers and civil-society organizations, and relate them to governance and international mechanisms that might play a role in agroforestry adoption. Market access for produce from diversified agroforestry remains difficult, as does its processing and transport. Moreover, farmers have difficulties in achieving the quantities and homogenous quality demanded by markets in the major cities. But most importantly, farmers and civil-society organizations saw little government support, although ‘ecological production in harmony with Mother Earth’ is prescribed by law and the constitution. Agroforestry farmers needed support most urgently in the initial phase, when investment costs are high and returns low. They suggested affordable credits, subsidies for diversified farming systems, and insurance against fire. We identified important albeit small steps towards developing markets for agroforestry products, but government support – mostly in the form of diesel subsidies, materials, and infrastructure – mainly benefitted large-scale monocultures and cattle ranching. In response to this, interviewees opted for strengthening farmers’ organizations, for demanding support with the help of civil-society organizations, and for disseminating best practices. 相似文献

Mapping historical and contemporary agrarian transformations and capitalist infiltration in a complex upland environment: A case from eastern Nepal 下载免费PDF全文
The relationship that mountain communities have with global capitalism are complex, being mediated by a diverse topography and ecology, both of which provide opportunities for capital accumulation, while also isolating older, “pre‐capitalist” modes of production. This paper takes a case study valley from Nepal's eastern hills, tracing over two centuries of agrarian change and evolving interactions between “adivasi” and “semi‐feudal” economic formations with capitalism. In recent years, the expansion of markets, rising demand for cash, and climate stress have solidified migrant labour as a core component of livelihoods, and the primary mechanism of surplus appropriation from the hill peasantry. Through a focus on three altitudinal zones, however, it is demonstrated how the trajectory of this transformation, including the interactions with persisting pre‐capitalist formations, is mediated by both political–economic processes and the local agro‐ecological context. 相似文献

Time orientation and construal level: effects on eating and exercising behaviour and preferences 下载免费PDF全文
Jannette van Beek Michel J.J. Handgraaf Gerrit Antonides 《International Journal of Consumer Studies》2017,41(1):54-60
Eating and exercising behaviour are both characterized by immediate and future consequences. Consequently, consideration of these consequences (i.e. time orientation) predicts eating and exercising behaviour. We investigate whether construal level acts as an underlying mechanism of these relations. Students (N = 101) completed measures of consideration of immediate and future consequences (i.e. CFC‐food and CFC‐exercise), construal level, eating and exercising behaviour and preferences. For self‐reported eating and exercising behaviour, only direct effects of consideration of immediate and future consequences were found. For eating preferences, however, there was evidence of an indirect effect through construal level. A stronger tendency to consider future consequences led to a stronger preference for utilitarian (as compared with hedonic) food products through a more abstract construal level. All in all, construal level partially explains the differential relations between consideration of immediate and future consequences and eating and exercising behaviour and preferences. 相似文献

Global leaders agree on the need to substantially decarbonize the global economy by 2050. This paper compares potential costs associated with different policy pathways to achieve tourism sector emission reduction ambitions (?50% by 2035) and transform the sector to be part of the mid-century decarbonized economy (?70% by 2050). Investment in emissions abatement within the tourism sector, combined with strategic external carbon offsets, was found to be approximately 5% more cost effective over the period 2015–2050 than exclusive reliance on offsetting. The cost to achieve the ?50% target through abatement and strategic offsetting, while significant, represents less than 0.1% of the estimated global tourism economy in 2020 and 3.6% in 2050. Distributed equally among all tourists (international and domestic), the cost of a low-carbon tourism sector is estimated at US$11 per trip, equivalent to many current travel fees or taxes. Exclusive reliance on offsetting would expose the sector to extensive and continued carbon liability costs beyond mid-century and could be perceived as climate inaction, increasing reputational risks and the potential for less efficient regulatory interventions that could hinder sustainable tourism development. Effective tourism sector leadership is needed to develop a strategic tourism policy framework and emission measurement and reporting system. 相似文献
