本文目的在于讨论和分析二氧化碳捕获和储存技术项目(CCS)作为清洁发展机制(CDM)项目的障碍和机遇。CCS被视为减少CO2人为排放量的选择方案之一,但在发展中国家,该技术面临着政策、成本和技术上的挑战。对这些国家而言,CDM几乎是发展CCS的唯一动机。本文分析了CCS作为CDM项目面临的项目边界、持久性、渗漏和可持续发展性的问题,并展望了未来的发展趋势。  相似文献

Urbanisation is truly a global phenomenon. Starting at 39% in 1980, the urbanisation level rose to 52% in 2011. Ongoing rapid urbanisation has led to increase in urban greenhouse gas (GHG) emissions. Urban climate change risks have also increased with increase in climate-induced extreme weather events and more low-income urban dwellers living in climate sensitive locations. Despite increased emissions, including GHGs and heightened climate change vulnerability, climate mitigation and adaptation actions are rare in the cities of developing countries. Cities are overwhelmed with worsening congestion, air pollution, crime, waste management, and unemployment problems. Lack of resources and capacity constraints are other factors that discourage cities from embarking on climate change mitigation and adaptation pathways. Given the multitude of problems faced, there is simply no appetite for stand-alone urban climate change mitigation and adaptation policies and programmes. Urban mitigation and adaptation goals will have to be achieved as co-benefits of interventions targeted at solving pressing urban problems and challenges. The paper identifies administratively simple urban interventions that can help cities solve some of their pressing service delivery and urban environmental problems, while simultaneously mitigating rising urban GHG emissions and vulnerability to climate change.  相似文献

Climate change-related impacts have the capacity to substantially influence Small Island Developing States (SIDS) in the Caribbean. Currently, many SIDS are engaged in large-scale vulnerability assessments that aim to identify, analyse, and inform solutions to mitigate climate change-related impacts. Many of these assessments, while useful, place little emphasis on the local stakeholders' perceptions of climate change. One such Caribbean community impacted by climate-related change is Providence Island in Colombia. Using a vulnerability assessment framework (Marshall, P.A. et al. 2010. A framework for social adaptation to climate change: sustaining tropical coastal communities and industries. Gland: IUCN Publication Services), researchers interviewed island residents (N = 23) about their perceptions of climate change, impacts on the local environment, and how the island community may adapt. All interviews were transcribed and analysed using a priori and open coding to identify patterns of and relationships between stakeholders' responses. Results indicate that local perceptions of climate change are linked to (1) environmental knowledge, (2) environmental awareness, attitudes, and beliefs, and (3) perceptions of risk. Implications for local adaptive strategies, education, communication, and suggestions for engagement at the local level are discussed.  相似文献

气候变化对中国旅游业持续发展的影响及应对措施   总被引:2,自引:0,他引:2  
气候变化已不同程度地威胁到中国旅游业持续发展所依赖的主要生态系统,使旅游业遭受到巨大的经济损失,并且使旅游业面临着改变其产品和形象的威胁,可能进一步加剧旅游业与自然保护之间的冲突、凸显社会公平问题。尽管中国现行立法已为保障旅游业持续发展提供了相应的制度支撑,但远不足以应对气候变化对中国旅游业持续发展带来的严峻挑战。当前迫切需要开展旅游业的可持续管理与教育、培育旅游市场和发展循环经济等联合行动。  相似文献

ABSTRACT: A greenhouse warming would have major effects on water supplies and demands. A framework for examining the socioeconomic impacts associated with changes in the long-term availability of water is developed and applied to the hydrologic implications of the Canadian and British Hadley2 general circulation models (GCMs) for the 18 water resource regions in the conterminous United States. The climate projections of these two GCMs have very different implications for future water supplies and costs. The Canadian model suggests most of the nation would be much drier in the year 2030. Under the least-cost management scenario the drier climate could add nearly $105 billion to the estimated costs of balancing supplies and demands relative to the costs without climate change. Measures to protect instream flows and irrigation could result in significantly higher costs. In contrast, projections based on the Hadley model suggest water supplies would increase throughout much of the nation, reducing the costs of balancing water supplies with demands relative to the no-climate-change case.  相似文献

ABSTRACT: Long term trends in Japan's annual and monthly precipitation are investigated in this study. The statistical significance of a trend at a study site is assessed by the Mann‐Kendall (MK) test, and field significance of trends in climatic Regions II, III, and IV is evaluated using the bootstrap test preserving cross correlation. The practical significance of a trend is judged by a percentage change of the sample mean over an observation period. The field significance assessment demonstrates that annual precipitation in Region II did not show any significant change, but regional precipitation shifts occurred in different months. Precipitation significantly increased by 12.2 percent in May, while it significantly decreased by 12.0, 10.5, 15.6, and 19.7 percent, respectively, in April, September, October, and December. In Region III, annual precipitation declined by 11.8 percent, and monthly precipitation significantly decreased from September through January and in April, with the greatest decrease (38.2 percent) in December. In Region IV, significant reductions occurred in both annual precipitation (by 15.6 percent) and monthly precipitation from September through February and in June and July, with the worst reduction (44.7 percent) in December.  相似文献

There is now an emerging sense of the scope and nature of response that can be implemented at building and neighbourhood scales to help adapt cities and urban areas to the changing climate. In comparison, the role of larger natural and semi-natural landscapes that surround and permeate cities is less well understood. Addressing this knowledge gap, this paper outlines two case studies that describe and map the flood risk management functions offered by green infrastructure landscapes situated within the Urban Mersey Basin in North West England. The case studies establish that areas potentially exposed to flooding can be located at some distance, and within different jurisdictions, from upstream areas where the flood hazard may be generated and could be moderated via functions provided by green infrastructure landscapes. This raises planning and governance challenges connected to supporting and enhancing flood risk management functions provided by green infrastructure landscapes.  相似文献

This study adopted an open-ended exploratory approach to elicit the perspectives of a selection of six Climate Challenge Fund projects. This central idea is that communities' perspective on attempted carbon reduction initiative in their areas has use in other contexts and could enable better design of such interventions in future. The main finding was that emphasising local benefits was conducive to their achieving local involvement in the project. The results of this research should be tested in other contexts. Three broad implications for the design of community carbon reduction initiatives are raised in assuming these outcomes are correct. First, the community hosting such initiatives should be perceived to hold a degree of power over the project. Second, central authorities should not be overly prohibitive about the motivations of those participating in such projects. Finally, the use of non-environmental messaging has value in shifting people to more pro-environmental behaviours.  相似文献

应对气候变化是全球各国共同面临的严峻挑战,而不同国家由于其自身发展阶段、治理水平等存在差异,气候治理模式也呈现不同特征。本文系统梳理了英国、德国、法国、美国、欧盟、日本、韩国、印度、巴西、南非等全球主要经济体和排放体的气候政策体系与机构设置情况,将其气候治理模式分为五类:政策引领型、法律缺失型、整体完备型、部分行业先行型和政策协调双缺失型,并从政治体制和党派态度、资源禀赋和强势部门、战略定位与气候叙事、公众态度与国际事件四个维度进行了影响因素的分析。建议我国未来可在加快推进气候立法、充分发挥制度优势、形成中国特色治理方案、推动建立公平合理互利共赢国际治理体系、落实完善“1+N”政策体系等方面加强工作部署,提升应对气候变化治理水平,促进“双碳”目标尽早实现。  相似文献
