Uncovering causes and effects of desertification using a Leopold matrix in Binh Thuan Province,Vietnam

Vietnam is a coastal country projected to be heavily affected by climate change.Binh Thuan Province is part of the driest region of Vietnam and is prone to desertification.An expert panel participated in developing a Leopold matrix which allowed for identification of desertification impact factors on the province's socioeconomic activities and assessment of the strength of cause-effect relationships in terms of magnitude and importance.Land use planning,surface water,and the length of the dry season are considered the most important causes,with the overall highest scores for both magnitude and importance in the cause-effect relationship.The largest effects of the different factors are perceived on water supply for agriculture and household use.Water availability and land use planning are important remedial action domains,while drought and land cover require monitoring to assess impacts.The indicators of cause and effect can be used in a longer-term general monitoring and assessment framework to combat desertification in the area.     

Questioning the Doubt: Climate Skepticism in German Newspaper Reporting on COP17

Despite numerous international studies on climate change, there is skepticism in the media and it is prominent in public opinion polls. This article focuses in particular on the framing of climate skepticism in Germany, a country that, in the main, is said to be convinced about climate change. By using a two-step content analysis of 379 news articles (print and online) we demonstrate that climate skepticism is present in German news media reporting on the 17th Conference of the Parties (COP17) to the United Nations Framework Convention on Climate Change in Durban, South Africa. We identify two overarching skepticism frames: skepticism about the phenomenon of climate change and about climate science. Our analysis further shows that climate skepticism is not exclusive to a specific political ideology, even though a newspaper's ideology may influence how skeptical frames are being evaluated.     

Overview of regulatory/policy/economic issues related to carbon dioxide

This is an overview of Session 2c dealing with the regulatory, policy and economic issues related to carbon dioxide and its impact on global climate change. The information is taken from the two papers presented in this session (the U.S. Perspective by Dennis Leaf and the European Perspective by Hans J.H. Verolme) and from the panel discussion that took place at the end of the session. The overview focuses primarily on the policy responses of both the United States (US) and the United Kingdom (UK) to changes in global atmospheric pollution. To a lesser extent, the progress of policy responses to these changes is discussed. The United Nations Framework Convention on Climate Change (UNFCCC) has been signed and ratified by over 180 countries. The UNFCCC contained no binding targets or timetables for emissions reductions. The Kyoto Protocol [United Nations. Kyoto Protocol to the United Nations Framework Convention on Climate Change. UNEP.IUC/99/10. Chatlelaine, Switzerland: United Nations Environment Programme's Information Unit for Conventions, for the Climate Change Secretariat, 1997] to the UNFCCC did contain targets and timetables for reductions of greenhouse gases on the part of developed countries. The US has signed but not ratified the Kyoto Protocol. The US has experienced some movement to reduce greenhouse gas emissions on the part of various levels of government, as well as the private sector. The UK's commitment to reducing green house gases is laid down in the UK Climate Change Programme 2000. The UK is a member of the European Union (EU). In this context, an example of EU-wide progress, the voluntary agreement with car manufacturers to reduce CO(2) emissions in new vehicles, will be discussed. In addition, there will be some discussion on the UK CO(2) trading scheme that created the first market in the world in April 2001. Overall, the policy process is constantly informed by scientific research. In the case of climate change, much of this work is carried out under the auspices of international scientific panels.     

Climate change adaptation and the African fisheries: evidence from the UNFCCC National Communications

Climate change can cause significant (un)foreseen changes in the fisheries sector. However, adaptation has the potential to moderate some of the impacts. This paper explores the challenges faced by both freshwater and marine fisheries sector in addressing climate change and teases out intervention measures from 21 African countries. The paper uses document analysis and draws selected analysis parameters from the grounded theory. The data are obtained from the United Nations Framework Convention on Climate Change National Communication reports. Among the key adaptation measures emerging from the analysis are: fish breeding, integrated coastal management, putting in place appropriate policies, water and flood management as well as research and development. The study concludes that adaptation in the African fisheries sector should be prioritised, an aspect that could also apply elsewhere in the world to enhance food security.     

协同治理:2030年可持续发展议程与应对气候变化的国际制度分析

对国际议程间的关联性分析已经成为全球治理中的重要问题。特别是,由联合国引领的全球发展与应对气候变化问题,已经占据了当前国际政治议程的首要位置,两者的协同直接影响到全球治理的有效性。《2030年可持续发展议程》与《巴黎气候协定》不仅具有共同的规范性基础,而且两者通过议题衔接和叠加已经形成了密切的治理关系,国际制度关联性日益突出。从目前来看,这种关联性体现了以下特点:第一,嵌入关系。可持续发展议程的目标之一是应对全球气候变化,《巴黎协定》的治理目标已经嵌入联合国可持续发展议程之中,但也与一些目标存在矛盾,因此,协同治理具有必要性。第二,指标对应。《巴黎协定》下的“国家自主贡献”细化项目与可持续发展议程中的大部分指标已经形成对应关系,治理具有同质性。第三,制度间倡议交叉与功能外溢。其协同治理关系具体表现在诸多层面上,特别是在联合国系统内的协调、治理模式的趋同、资金渠道的整合、围绕联合国可持续发展议程所进行的发展机构改革,以及联合进行政策倡议、规则建构及政策制定等方面。从制度关系演变的角度来看,两者协同治理的类型正在发生变化,制度互动在不同层次上不断累积,并逐渐转向伙伴型的协同治理模式。     

The Vandaclim Simulation Model: A Training Tool for Climate Change Vulnerability and Adaptation Assessment

This paper describes a training course on climate change vulnerability and adaptation assessment. The course, developed in partnership with the CC:TRAIN Programme of the United Nations Institute for Training and Research (UNITAR), aims to enhance the capacity of developing countries to make their national communications to the United Nations Framework Convention on Climate Change. The paper focuses on a simulation model called VANDACLIM, which was developed as a pedagogical tool to facilitate the training. Four sectors are modelled within VANDACLIM (agriculture, public health, water resources, and coastal zone) and are used as a basis for helping to conduct an integrated, multi-sectoral assessment for the imaginary, sub-tropical country of Vanda. The learning-by-doing approach, encapsulated in the application of VANDACLIM to complete a mini-assessment for Vanda, proved to be very successful when trialled at a training workshop in Zimbabwe. Both the training course and VANDACLIM have been adapted subsequently for application in small island states and plans are underway for extension to other environments and regions of the world.     

Bound to lead?Rethinking China's role after Paris in UNFCCC negotiations

As the biggest global emitter of greenhouse gases, China is an extremely important actor in international climate negotiations. During the climate summit in Copenhagen, China was blamed for its uncooperative positions particularly from the US side. However, in the Paris climate process, China's participation in international negotiations is more active, and has become a wellrecognized promoter of the Paris Agreement. To understand China's climate policy, the economic and diplomatic strategy should be taken into consideration, especially the changes in the ideas of China's global governance rooted from domestic politics discourse. Moreover, China's symmetrical changes within domestic and international dimension possibly bring out more balanced climate policies and thus the constructive role of China will be the normalcy in the future United Nations Framework Convention on Climate Changenegotiations. However, the negotiations after the US presidential elections may change dramatically and yields great uncertainty for global action. Thus, the vacuum of power may be a possible scenario. Will China reinforce its role toward leadership or go back to group politics? This article examines China's concerns, motives, and possible path to climate leadership in the current debate.     

The Paris Agreement and climate change negotiations: Small Islands,big players

Climate change poses an existential threat to Small Island Developing States (SIDS). They have played a leading role in raising awareness of climate change on the international stage and advocating for strong climate action, notably through the Alliance of Small Island States (AOSIS). Despite their heterogeneity, they succeeded in building a common diplomatic discourse and influencing strategy, and mobilized political leaders as well as talented negotiators and advisors.Small Island States were a crucial group in the negotiating period up to, during the 21st Conference of the Parties to the United Nations Framework Convention on Climate Change (COP21), and for the entry into force of the Paris Agreement. SIDS succeeded to secure their special circumstances as vulnerable countries, demonstrated leadership in raising ambition to reduce greenhouse gas emissions to help secure an ambitious long-term temperature goal of limiting global warming to below 1.5 °C, and advanced the complex debate on loss and damage.Small Island States face major challenges to advance their leadership on climate change moving forward: securing immediate actions for those particularly vulnerable countries and increasing their influence within and outside the climate change negotiations. For Small Island states, the 1.5 °C goal should be considered “the visible part of the iceberg” for their diplomacy in a post-Paris context.     

Impacts of climate change on Chinese ecosystems: key vulnerable regions and potential thresholds

China is a key vulnerable region of climate change in the world. Climate warming and general increase in precipitation with strong temporal and spatial variations have happened in China during the past century. Such changes in climate associated with the human disturbances have influenced natural ecosystems of China, leading to the advanced plant phenology in spring, lengthened growing season of vegetation, modified composition and geographical pattern of vegetation, especially in ecotone and tree-lines, and the increases in vegetation cover, vegetation activity and net primary productivity. Increases in temperature, changes in precipitation regime and CO₂ concentration enrichment will happen in the future in China according to climate model simulations. The projected climate scenarios (associated with land use changes again) will significantly influence Chinese ecosystems, resulting in a northward shift of all forests, disappearance of boreal forest from northeastern China, new tropical forests and woodlands move into the tropics, an eastward shift of grasslands (expansion) and deserts (shrinkage), a reduction in alpine vegetation and an increase in net primary productivity of most vegetation types. Ecosystems in northern and western parts of China are more vulnerable to climate changes than those in eastern China, while ecosystems in the east are more vulnerable to land use changes other than climate changes. Such assessment could be helpful to address the ultimate objective of the United Nations Framework Convention on Climate Change (UNFCCC Article 2).     

Obstacles to climate change adaptation decisions: a case study of sea-level rise and coastal protection measures in Kiribati

International aid is increasingly focused on adaptation to climate change. At recent meetings of the parties to the United Nations Framework Convention on Climate Change, the developed world agreed to rapidly increase international assistance to help the developing world respond to the impacts of climate change. In this paper, we examine the decision-making challenges facing internationally supported climate change adaptation projects, using the example of efforts to implement coastal protection measures (e.g. sea walls, mangrove planting) in Kiribati. The central equatorial Pacific country is home to the Kiribati Adaptation Project, the first national-level climate change adaptation project supported by the World Bank. Drawing on interview and document research conducted over an 8-year period, we trace the forces influencing decisions about coastal protection measures, starting from the variability and uncertainty in climate change projections, through the trade-offs between different measures, to the social, political, and economic context in which decisions are finally made. We then discuss how sub-optimal adaptation measures may be implemented despite years of planning, consultation, and technical studies. This qualitative analysis of the real-world process of climate change adaptation reveals that embracing a culturally appropriate and short-term (~20 years) planning horizon, while not ignoring the longer-term future, may reduce the influence of scientific uncertainty on decisions and provide opportunities to learn from mistakes, reassess the science, and adjust suboptimal investments. The limiting element in this approach to adaptation is likely to be the availability of consistent, long-term financing.     

Sustainability indicators for clean development mechanism projects in Vietnam

The Clean Development Mechanism (CDM) is one of the flexible instruments of the Kyoto Protocol designed to combat climate change so as to bring advantages to developing countries and developed countries alike. Indeed, CDM projects have a two-fold objective: to offset greenhouse gas emissions and to contribute to sustainable development in the host country. However in many cases, the latter objective appears to be marginalized. This is at least partly due to the difficulties surrounding the definition and the measurement of sustainability, in particular in a developing country context. To assess CDM projects’ contribution to sustainable development in the host country, scholars and practitioners need adapted indicator sets. A set of indicators were developed by way of an iterative Delphi approach amongst selected Vietnamese experts. The Delphi approach allowed a systematic collection of the experts’ judgements on the sustainability indicators through a set of sequentially applied questionnaires, interspersed with feedback from earlier responses. This exercise resulted in the selection of a set of 36 indicators, which emphasise economic efficiency, public health and pollution issues. The exercise yielded a locally supported and context-specific set of sustainability indicators that will allow Vietnamese decision-makers to enhance the sustainability of the approved CDM projects. In the future this set should be continually improved through real-life application and further participation from local stakeholders. This study is a first step in a long-term process towards developing an adapted toolkit for sustainability assessment of CDM projects in Vietnam.     

Loss and damage related to climate change: connotations and response mechanism

Global mitigative and adaptive efforts have not been able to effectively address the adverse impacts caused by climate change. Therefore, a direct solution is needed to address the significant resulting loss and damage (L&D). During the United Nations Framework Convention on Climate Change held in Doha in 2012, the issue of responding to L&D arising from climate change gained sudden traction and became one of the key issues that affected the outcome of the convention. In this paper, a study on the definition and connotations of L&D arising from climate change was conducted, together with an analysis of its relationship with related concepts, namely impacts, vulnerability, and risks. This led to the proposal of an L&D conceptual model that is more comprehensive, with the recognition of the need to address the issue through effective supplementation of existing mitigative and adaptive efforts. A systematic elaboration of an L&D response mechanism was made based on politics, law, and the market, leading to a preliminary presentation of a possible format for an L&D mechanism. Potential academic research directions for L&D were also proposed that could serve as references for the establishment of international and national L&D response mechanisms and related research.     

Establishing a measurement,reporting, and verification system for climate finance in post-Paris agreement period

The measurement, reporting, and verification (MRV) of climate finance was originated from discussions under the United Nations Framework Convention on Climate Change (UNFCCC). It has been one of the key issues of global climate negotiations since 2009 and will continue to be of significant importance in addressing climate change and strengthening international trust. This paper analyses the concept, the objective, and the progress of the MRV of climate finance based on reviews of the latest literature and think-tank reports regarding climate finance regime and MRV. Following the analysis, challenges faced with the MRV of climate finance are illustrated. This paper presents that the comparability of climate finance data needs to be improved due to the variety of methodologies used for disaggregating climate finance. In addition, the integrality of the MRV system of climate finance has been impaired by the lack of feedback mechanism from the recipients to the contributors in reporting system. Furthermore, although accounting system of climate finance has been developing and improving, it remains incapacity in providing accurate data on disbursed climate finance. Responding to the above challenges, this paper proposes the key tasks in establishing a comprehensive MRV system for climate finance at international level. The tasks involve developing a measurement system with consistent data basis and accounting basis, a reporting system with more detailed guidance and standardized formats, as well as a verification mechanism balancing top-down and bottom-up review processes. In the last section, this paper concludes that the establishment of an improved MRV of climate finance requires concerted cooperation and negotiations between developed and developing country Parties under the UNFCCC. As one of the few developing country donors to the Global Environmental Facility (GEF), China is suggested to clarify its propositions as a developing country in aspects such as concept, coverage, and architecture of climate finance and MRV system, and gain bargaining power in improving operating and technical rules of international climate finance regime.     

低碳技术国际转移的双重博弈研究

为探求《联合国气候变化框架公约》(以下简称《公约》)下促进低碳技术国际转移的机制,本文运用博弈论方法,构建了一个双重博弈模型框架,分别从企业层面和国家层面的角度建立相应的博弈模型,并将二者结合起来,分析相应的均衡及其政策含义。研究表明,国家在低碳技术国际转移中起着关键作用,存在广阔的政策空间;在巴厘路线图谈判中,国际社会应该积极推进气候变化领域《技术合作议定书》的建立,提出《公约》下对发达国家的可测量、可报告、可核实的技术转移义务,规定发达国家必须通过技术转移在发展中国家实现量化的减排;《公约》下应该建立单独的技术转移资金机制,设立专门的技术转移基金,发达国家通过任务分担(辅之以赠款)提供资金,鼓励和资助技术转移;对于转移难度太大或者涉及核心竞争力的低碳技术,发展中国家(企业)必须加强自主研发。     

《巴黎协定》后的气候资金测量、报告和核证体系构建研究

气候资金测量、报告和核证产生于《联合国气候变化框架公约》(简称《公约》)之下,2009年以来一直是全球气候谈判的重点之一,也是未来全球共同应对气候变化和不断增进国际信任的重要环节。《巴黎协定》达成的"每两年通报"的决定,将推动气候资金测量、报告和核证得到不断的加强和完善。本文通过梳理最新的气候资金机制以及测量、报告和核证的文献资料和智库报告,分析了气候资金测量、报告和核证的内涵、目标和最新进展,以及公约框架下面临的挑战。分析指出,目前不同的气候资金统计和核算机构的资金分类标准存在差异,数据可比性有待改善;缺乏从资金上游到下游的反馈机制,影响气候资金测量、报告和核证体系的完整性;气候资金计量体系虽然正在发展和完善之中,但仍然难以提供准确的资金"支付"数据。据此,文章提出了构建综合性的国际气候资金测量、报告和核证体系的重点任务:建立具有统一数据基础和核算口径的气候资金测量体系,建立操作指南更为详细、形式更为标准统一的气候资金报告体系,以及"自上而下"和"自下而上"相结合的气候资金核证机制。最后,文章指出国际气候资金测量、报告和核证体系的构建需要发达国家和发展中国家在坚持公约资金机制的基础上共同参与和协作。作为国际上少数几个向GEF捐资的发展中国家之一,中国在参与过程中应力争体现发展中国家对气候资金性质的主张以及对测量、报告和核证机制的关键概念和范围界定的主张,影响国际气候资金机制的运营规则和技术规则。     

Press Briefings in International Climate Change Negotiations

Press conferences are an important element of a government's communication strategy at climate change summits. From a theoretical perspective, press conferences should serve two main functions: exerting pressure in negotiations and informing the public. These functions correspond to two logics of action: a logic of consequence where governments use press conferences as negotiation tools and a logic of appropriateness where governments organize press conferences to increase transparency. Based on new data from the United Nations Framework Convention on Climate Change archives, we find limited support for these two logics of action. Neither democracies, which, we argue, are more likely to follow a logic of appropriateness, nor vulnerable countries, which are more likely to follow a logic of consequence, organize systematically more press conferences. Other factors, such as capacity and a government's function in the negotiation structure, seem to play a more important role.     

Global progress in climate change adaptation policies and its implication for China

This paper reviews the progress in climate change adaptation (CCA) policies both under the United Nations Framework Convention on Climate Change (UNFCCC) and in major regions and countries, including the EU and its major member countries, the influential developed countries in the Asia-Pacific region, the emerging economies and the least developed countries (LDCs). The progress made in China in CCA policies is also reviewed and compared with that in other countries. Finally, good international practices are proposed for China’s policy development. It is found that adaptation has been given the same priority as mitigation since the twenty-first century with regard to climate change-related actions. The topics related to adaptation in the international climate change negotiations under the UNFCCC have evolved from mechanisms for finance and technology development and transfer exclusively in the early stages to implementation of practical adaptation programs and actions. Since 2006, major developed and developing countries have frequently set forward specific CCA policies or general climate change policies involving adaptation in the form of laws, frameworks, strategies, and plans. The LDCs have also been working on National Adaptation Programmes of Action and subsequent National Adaptation Plans with the support from the financial mechanisms under the UNFCCC. Therefore, globally, it has become a common practice to develop national or regional policies to plan and guide CCA actions. China has established climate change policies involving adaptation at the national, regional, and sectorial levels since 2007. However, these policies have strong limitations in their knowledge base, strategic positioning, contents, and implementation mechanisms, e.g. lack of a sound knowledge base, an international perspective, clear responsibilities for policy implementation, and appropriate monitoring and evaluation mechanisms. It is recommended that China should further strengthen its technical capabilities in climate change projections as well as impact, vulnerability, and risk assessment, and develop methodologies and techniques for the preparation, impact assessment and implementation of CCA policies. Furthermore, future CCA strategies or plans should be developed with an emphasis on China’s vision and strategic position on the world stage.     

Toward a ‘Sustainable’ land degradation? Vulnerability degree and component balance in a rapidly changing environment

Land degradation is a process negatively affecting environmental sustainability and requires permanent monitoring for understanding its nonlinear trajectories of change over time and space. Environmental sustainability is linked to a theoretical definition of dynamic balance among various components contributing to the ecosystem quality and functioning. The aim of this study is to develop a diachronic analysis (1960–2010) of the equilibrium/disequilibrium condition of key environmental factors (climate, soil, vegetation, land-use) influencing the vulnerability of land to degradation in a Mediterranean country experiencing processes of desertification at the local scale. Three indicators of components’ balance have been proposed and tested for spatial and temporal coherence. Land classified at high vulnerability and low component’s balance has been identified as a possible target for mitigation strategies against desertification; the surface area of this class increased rapidly during 1960–2010 and concentrated in high-intensity agricultural lowlands of northern Italy.     

关于中国西南石漠化的若干问题

石漠化是西南岩溶山地脆弱生态系统发生的土地退化。根据已有的经验和研究成果,深入探讨了中国西南岩溶山地喀斯特石漠化的科学内涵、成因、发展过程、评价指标及防治机理等。土壤和植被是岩溶环境中最为敏感的自然环境要素,可能是石漠化过程的主要自然成因,而以土地利用为表现形式的强烈人类活动为驱动力;石漠化的发生发展过程即人为过程→生物学过程→加速的地学过程。石漠与石漠化,二者属于完全不同的范畴,不同空间尺度的石漠化评价应有不同的评价指标、标准和石漠化生态基准的多样性,以便为石漠化的演化研究及生态重建起一定的参考作用。鉴于石漠化现象在我国现实中存在的客观性、在理论概念上的模糊性及在生态治理中的急迫性,有必要加强石漠化在不同时空尺度下的驱动机制研究,特别是人类驱动力的研究,加强原生岩溶生态系统和受损岩溶生态系统运行规律的研究。     

The application of the contingent valuation method in estimating the climate change mitigation and adaptation policies in Greece. An expert-based approach

When dealing with the ecological, social and economic impacts of climate change, it is important for each country to formulate and implement mitigation and adaptation measures. In this context, the present paper examines the application of the contingent valuation method (CVM) for the monetary estimation of the Greek national mitigation and adaptation climate change costs. To this purpose, the CVM in this case study has been applied to the Greek climate change experts only as, theoretically, they represent the most informed part of Greek society in technical and economic aspects of the climate change. Therefore, the findings of this paper express strictly the opinions of the national experts and are not representative of the general population. The monetary estimates include the experts’ WTP for mitigation and adaptation measures as well as their preferences on that percentage of the national GDP that should be funding such measures at the present as well as the future time-scale. In addition, questions concerning the political and institutional climate change settings are included in the survey, providing a more comprehensive socioeconomic analysis in this particular study.
