中国适应气候变化技术分类研究   总被引:2,自引:0,他引:2  
近百年来,全球气候变化呈现出变暖的主要特征,气候变化所带来的影响日趋严重,其所造成的经济损失在全球范围内显著上升。适应气候变化是现阶段应对气候变化行动的重要方面,适应气候变化的技术分类研究是清晰认识适应气候变化的基础,是实现适应技术集成并构建合理有效的适应技术体系的手段。本文通过对适应气候变化技术分类问题的分析,提出了不同的适应气候变化技术分类方式,气候变化影响过程、区域、领域、适应目的、适应机制、适应时效、适应程度、适应层面等,针对气候变化及其影响梳理了中国不同区域与不同领域的适应气候变化技术清单。从气候变化影响过程来看,可以将适应气候变化技术分为气候变化影响发生前、发生过程中、发生后三类;从区域与领域气候变化影响来看,可以将适应气候变化技术分为八大区域与七大领域;本研究重点针对八大区域与农业、水资源、生态环境三大领域进行了分析。通过研究发现,现阶段适应气候变化技术分类研究尚存在一些问题,适应气候变化技术分类的导向不明确,造成对适应技术认识的不清晰;适应气候变化技术的分类往往与分层混淆在一起,导致人们对适应气候变化技术的认识和理解出现偏差;适应气候变化技术分类对适应行动的指导作用存在不足。综合来看,对适应气候变化技术进行精细分类,可以为适应气候变化技术的筛选、集成、效益评估奠定基础,推进适应气候变化行动高效有序开展,为适应气候变化技术体系构建提供支撑。  相似文献

Abstract

For the adverse impacts of climate change, China government should place the problem of adaptation to climate change on the agenda. It is time to institute and implement a state adaptive strategy to reduce the adverse impacts on economy, community and people's health and life by international cooperation and our own endeavor. A state strategy of adaptation to climate change should be closely linked with other current interrelated national strategies, and they should be supplemented and improved by each other. This paper discusses the roles of the state strategy of adaptation to climate change in the state climate change integrative strategy, the environmental protection strategy, and the sustainable development strategy in China. Furthermore, it proposes the main aims of the state adaptive strategy of China.  相似文献

气候变化已成为不争的事实.减缓和适应是人类应对气候变化的两类主要措施,在气候变化减缓行动难以很快奏效的情形下,采取具有针对性的适应战略已经成为世界各国更为紧迫的选择.一个有效的适应行动机制需要全社会的广泛参与,而公众和决策层对气候变化的认知是适应行动机制的形成基础.本文以银川阅海湿地适应气候变化能力建设为研究案例,从政府部门和社会公众两个层次进行讨论,比较其对气候变化的认知程度及其对适应措施的评价和需求,以期对适应气候变化策略的认知基础研究提供依据.研究结果表明,无论社会公众和决策层,适应气候变化的意识基础均已基本形成,但公众的认知基础要弱于决策层,并且在认知的准确程度上低于决策层;公众和决策层对气候变化适应政策的实施都做出了正面的评价,但决策层的评价普遍显著高于公众;对于适应政策的需求,公众的政策需求主要集中在公共服务方面,而决策层的适应策略是多方位的,也包括通过限制个人行为来获得公共利益.  相似文献

This article proposed the concept of"climate capacity"as a way of measuring human’s adaptiveness to climate change.This article also focused on the related concepts like ecological carrying capacity,water resources carrying capacity,land carrying capacity as well as population carrying capacity.The concept of climate capacity was articulated against a background of global climate and environmental change.Essentially,China’s efforts to adapt to climate change was a matter of improving climate capacity,which is the ecosystem as well as the frequency,the intensity and the scale of human’s social activities that the climatic resources of a particular geographic area were supposed to support.The climate capacity has two components.One is the natural climate capacity,which includes temperature,sunlight,precipitation,extreme climatic events,etc.The other is the derived climate capacity,which includes water resources,land resources,ecological systems,climatic risks,etc.The climate capacity can be developed or be transferred between regions by taking engineering,technology or regime-based adaptive measures.However,these adaptive measures must be implemented under the principle of economic rationalism,ecological integrity,climate protection,and social justice.It is expected that by combining the climate capacity and its threshold value with the assessment of climate change risks,we are able to predict the optimal population carrying capacity and the scale of socioeconomic development,and furthermore,provide policy support for the socioeconomic development strategy and adaptive planning.In the regions with high climate capacity,there is a symbiotic relationship between adaptation and socioeconomic development.But,in the regions with limited climate capacity,irrational development may further damage the environment.Taking the Yangtze River delta,a region with high climate capacity,and a region of Ningxia,a region with limited climate capacity,as illustrative examples,the authors of this article analyzed the policy implications of climate capacity and further made suggestions on the problems of capacitylimited adaptation and development-driven adaptation.This article argued that the concept of climate capacity can not only be used as an analytical instrument of climate change economics,but also it can provide research support for planning regional adaptation and development with climate change impact and risk assessments.  相似文献

国际上对气候因素引致人口迁移的直接关联性和重要程度一直存在争议.2010年我国西南地区遭受的特大千旱给探索极端气候事件和气候变化移民之间的复杂关系提供了研究背景.在此特大干旱影晌下,当地农村居民是否、以及怎样采用迁移的方式来应对?本文以2010年8-9月在受灾严重的云南省昆明市寻甸县所进行的田野调查为基础,揭示了特大干旱背景下当地农村人口的迁移行为及特征.调研结果表明在所调查的村组并未因此极端气候事件而引起大规模的气候变化移民活动,无论是暂时的还是永久的.为了解释灾后当地农村人口的迁移选择,本文引入“气候变化一人口迁移响应”的基本理论框架模型,考虑公共和私人两个层面的作用,对当地政府、村集体和农户自身的灾后适应行为进行深入分析和效果评价.结果表明在公共层面的各类帮扶和救助下,农户自身亦采取了多样化的适应措施,两个层面适应行为的共同作用缓解了特大干旱给农户生计带来的压力,使得农户家庭成员的迁移并不成为必须的选择.  相似文献

While many national governments struggle to maintain global climate change as a high priority issue, many local governments are taking action to fill the policy gaps. This study examines how local governments across the United Kingdom of Great Britain are reframing climate change. We compiled a dataset of newspaper publications covering climate change over a 10-year timeframe, plus survey and interview responses from local governance practitioners, to identify a shift in national discourse that has changed the priority level of climate change in UK local governance. This paper argues that many local governments are strategically reframing climate change as alternative issues in order to make progress in climate adaptation planning.  相似文献

ABSTRACT

Drought is defined, experienced, and communicated about in multiple ways. This case study examines individual definitions of drought (timing, impacts, and severity) and attitudes about climate change. Household surveys (n?=?120) were conducted in Cimarron County, Oklahoma and Union County, New Mexico using a stratified random sampling method to select farmers, ranchers, and town residents. Information about drought is primarily communicated between neighbors, friends, and family, as well as media and local governing agencies. Residents perceive the recent drought to be the worst drought on record, regardless of previous drought experiences. Residents reported widespread drought-related impacts on agriculture, environment, and society. Most residents see drought as cyclical and driven by natural causes, rather than human causes. We recommend adaptive drought communication engage more fully with identity, place, and history. Climate information should be presented in a relevant manner to diverse agricultural stakeholders with differing attitudes about climate change, management, and climate information.  相似文献

This study uses framing theory to analyze 38 studies on industry actors' climate change communication between 1990 and 2010. It identifies three consecutive phases, each characterized by one dominant master frame: in the early and mid-1990s the US fossil fuel and coal industry pushed the frame of scientific uncertainty. With the rundown to the Kyoto negotiations in 1997, the strategy shifted toward the socioeconomic consequences of mandatory emission reductions, particularly in the USA and Australia. At the same time, European industry actors started to promote industrial leadership in a climate protection, which today dominates across all the world regions. The study discusses potential triggers for the regional differences as well as the implications for further research.  相似文献

Over the past decade, scientists and journalists have prominently utilized the metaphor of a tipping point for drastic, irreversible and dangerous climate change. This paper shows how the tipping point metaphor became a multi-purpose bridge between science and the news media, describing how its meaning and use developed and diversified in interaction between these two domains. Within the scientific domain, the metaphor developed from a rhetorical device conveying a warning of drastic, irreversible and dangerous climate change to a theoretical concept driving empirical research. The news media soon picked up the tipping point metaphor for abrupt and dangerous climate change, turning it into a common part of the journalistic lexicon. Moreover, both science and the news media developed another, societal use of the tipping point metaphor, calling for radical societal change to avoid climate change catastrophe. The tipping point metaphor is hence not a monolithic notion but a highly versatile concept and expression, allowing it to be used for various communicative purposes by distinct stakeholders in different contexts.  相似文献

气候变化是当今人类社会面临的最严峻的全球性环境挑战之一,气候变化谈判关乎各国在气候秩序中的权力与义务,涉及到各国经济发展的根本利益,已经成为国际政治博弈的新舞台.根据联合国气候变化框架公约和巴厘路线图精神,发达国家应承担起历史责任,向发展中国家提供新的、额外的、可持续的、可预测的资金支持,帮助其应对气候变化的不利影响.但是,由于发达国家缺乏履行公约义务的政治诚意,长期以来在资金问题上同发展中国家展开了艰苦的斗争.哥本哈根会议后,全球应对气候变化资金呈现出资金来源多样化,资金规模逐渐缩水,资金治理机制对发达国家出资约束力近一步降低的趋势.各利益集团围绕资金机制谈判展开激烈博弈,欧盟与美国正在逐步突破“共同但有区别的责任”原则,争夺气候变化谈判领导权并力图将我国拉入出资国之列,发展中国家阵营逐步分化为“基础四国”、“小岛屿国家”、“最不发达国家”等,保持共同立场难度日渐增大.尽管绿色气候基金在德班会议后正式启动,若无资金注入,也只能为未来资金机制谈判带来不确定性.面对上述形势,我国应坚持公约基本原则,坚持发展中国家定位,加强综合研究及前瞻性判断,以积极的姿态和务实的态度参与应对气候变化的国际谈判,以争取自身的发展权益,维护国家核心利益.同时,探索在当前发展阶段下发展低碳经济和建立低碳社会的路线图,不断提高减缓和适应气候变化的能力,实现自觉减排,为全球应对气候变化做出积极贡献.  相似文献

This paper suggests some further avenues of empirical and theoretical investigation for media research on climate change. “Old” suggestions, whose significance, as we see it, needs to be further reinforced, are included, as are “new” ones, which we hope will generate innovative research questions. In order to integrate the analysis with knowledge generated by media research at large, we revisit four research challenges that media scholars have long grappled with in the investigation of journalism: (1) the discursive challenge, i.e. the production, content and reception of media discourse; (2) the interdisciplinary challenge, i.e. how media research might engage in productive collaboration with other disciplines; (3) the international challenge, i.e. how to achieve a more diverse and complex understanding of news reporting globally; and (4) the practical challenge, i.e. how to reduce the theory–practice divide in media research.  相似文献

ABSTRACT

The “common but differentiated responsibility” of developed and developing countries to mitigate climate change is a core principle of international climate politics—but there is disagreement about what this “differentiated responsibility” amounts to. We investigate how newspapers in developed countries (Australia, Germany, United States) and emerging economies (Brazil, India) covered this debate during the UN climate summits in 2004, 2009, and 2014. Newspapers in both types of countries attributed more responsibility to developed than to developing countries. In line with social identity theory, however, media in developed countries attributed less causal responsibility (blame) to other developed countries than media in emerging economies. The latter countries’ media, in turn, attributed less responsibility to other developing countries than media in developed countries. At the same time, in line with the “differentiated responsibility”, media in developed countries attributed more responsibility to their own countries than media in emerging economies.  相似文献

This paper explores the role that Internet and online technologies played in research dissemination and knowledge mobilization in a recent climate change research project, MC3. In addition, the team looked at the potential of online expert-practitioner research collaborations for these purposes. Electronic communication was seen as a key element for creating distributed networks essential to the project and for building new practitioner/research knowledge collaboratives. The paper discusses how online communication strategies and technologies were used for wide dissemination of its research outcomes. MC3's research dissemination and knowledge mobilization strategies are analyzed, using engagement as the primary measure, to gain insights on the effectiveness and challenges of using Internet-based tools for communicating climate change innovations and actions.  相似文献

Climatic records from equatorial eastern Africa and subtropical southern Africa have shown that both temperature and the amount of rainfall have varied over the past millennium. Moreover, the rainfall pattern in these regions varied inversely over long periods of time. Droughts started abruptly, were of multi-decadal to multi-centennial length and the changes in the hydrological budget were of large amplitude. Changing water resources in semi-arid regions clearly must have regional influences on both ecological and socio-economic processes. Through a detailed analysis of the historical and paleoclimatic evidence from southern and eastern Africa covering the past millennium it is shown that, depending on the vulnerability of a society, climatic variability can have an immense impact on societies, sometimes positive and sometimes disastrous. Therefore, the interconnected issue of world ecosystem and social resilience is the challenge for decision-makers if sustainable development is to be reached on global and local levels.  相似文献

A flurry of studies in recent years has analyzed the role of media in climate change communication. This article provides a systematic, large-scale, and up-to-date overview of the objects and characteristics of this research field through a meta-analysis. It identifies 133 relevant studies and analyzes them empirically. The results show that research activity has risen strongly over time, and that the analytical spectrum has expanded to include an increasing number of countries, more types of media including online and social media, and different methodological approaches. The analysis also demonstrates, however, that scholarship in the field still concentrates strongly on Western countries and print media.  相似文献

粮食安全:气候变化与粮食产地转移   总被引:2,自引:0,他引:2  
基于1985-2008年中国雀际面板数据,实证检验了气候变化对粮食种植规模与单位产量的作用机制,进而分析了产地转移对国家粮食总供给的影响.结论表明:①中国的稻谷、小麦、玉米产业正分别向黑龙江、河南、内蒙古等气候资源匮乏地区转移或集聚;②粮食产地转移的主导因素在于粮食作物与经济作物、种植业与畜牧业、农业与非农的成本收益比较,而气候变化因素仅处于附属地位;③基于规模效应、牧入效应以及回弹效应的作用机制,东北三省、河南、内蒙古等地区的增长潜质往往优于其他地区;④落后地区应对气候变化的生产与政策成本,往往要低于发达地区保留粮食生产的机会成本,粮食生产向欠发达地区转移应具有可持久性.粮食产地转移过程中,并未呈现粮食供给安全的“个体理性”与“集体理性”的冲突.中国应该在气象预报、水利设施、抗灾能力、中低产田改造等方面加大投入,摒弃区内平衡的传统观念,在全国范围内优化资源配置,并辅以国家粮食储备战略应对特大灾害的供给风险.  相似文献
