应对气候挑战，加快适应气候变化主流化进程

适应气候变化作为一项现实紧迫的任务,越来越受到国际社会的广泛关注,在国际谈判方面,近几年的UNFCCC缔约方大会已将其列为重要议题,而且也是发达国家和发展中国家两大阵营最容易达成共识的议题;在国家和区域层面,现阶段许多国家和地区已制定相应的适应战略、计划或行动方案在不断加强自身适应气候变化的能力建设;在管理手段或政策工具上,一些国家和地区机关和多边开发银行已经检验了把气候变化影响和适应纳入EIA的内容中的可能性。在中国的应对气候变化工作中,适应仍处于边缘地位。     

北京市水资源领域适应气候变化对策及保障措施探讨

气候变化问题日益凸显。应对和适应气候变化刻不容缓。然而,短期内无法有效减缓气候变化产生的不利影响。因此,有必要针对不同领域制定相应的适应措施来提高人们对气候变化的适应能力。北京作为人口众多的大城市及我国的缺水城市之一,气候变化无疑将加剧水资源的供需矛盾。本文针对北京市水资源现状及气候变化对北京市水资源领域已经形成的影响,从自然、工程、政策制度三个角度探讨了北京市水资源领域适应气候变化可采取的对策及保障措施。     

中国适应气候变化国家战略定位的初步探讨

由于生态环境脆弱、海岸线漫长、人均资源占有量低等基本国情的现实制约,中国极易受到气候变化的不利影响.这决定了中国必须把适应气候变化尽快列入政府议事日程,制定并实施适应气候变化的国家战略(简称适应战略),通过国际合作与自身努力,尽量消减气候变化对国民经济、社会发展、人民生活的不利影响.     

“适应气候变化”是发展中国家当务之急

在应对气候变化的问题上,人们长期以来对“减缓气候变化”高度关注,而对另一重要方面——“适应气候变化”却重视不够。2007年12月联合国气候变化大会通过的《巴厘行动计划》,将“适应气候变化”与“减缓气候变化”置于同等重要的位置。联合国环境规划署发布的《气候变化的影响和适应评估报告》,更是呼吁各国迅速采取行动适应气候变化,在制订经济发展计划时将适应气候变化问题纳入其中,易受气候变化影响的发展中国家和地区更该如此。

基于遥感技术的城市污水处理厂热岛效应研究

热岛效应已成为城市化发展中影响局地气候变化的重要因素之一.作为城市必要基础设施的一部分,城市污水处理厂对全球性气候变化的影响受到了广泛关注和研究,而对局地气候变化的影响却鲜有研究.文章首次尝试利用Landsat卫星遥感图像对1995年-2013年间苏州市11座城市污水处理厂进行了热岛效应研究,并对影响因素进行了初步分析.结果发现,11座城市污水处理厂热岛强度在18年间整体上增加了48％;从时间维度上来看,在污水处理厂施工建设或升级改造阶段,热岛强度都偏高.而根据回归分析发现,城市地表平均温度、污水处理厂的施工建设状态和主体处理工艺与WHII具有显著正相关性.     

IPCC综合报告：减缓与适应方案需加速部署

<正>2023年3月，政府间气候变化专门委员会（IPCC）发布了第六次评估报告（AR6）综合报告《气候变化2023》，本报告综合了AR6三个工作组和三个特别报告的主要结论，总结了气候变化的现状、影响、风险以及气候减缓和适应的路径。报告指出，气候变化已经影响到了全球每个地区，导致了许多极端天气和气候事件，这对自然和人类产生了广泛的不利影响。尽管目前世界各国都在减缓和适应领域已经取得了一些进展，但这相比于实现气候目标所需的水平仍然存在差距。

Climate change adaptation and mitigation: next steps for cross-sectoral action to protect global health

Effectively addressing the health risks of climate change necessitates an active crosssectoral approach because health risks arise predominantly via sectors such as water, agriculture and energy. Much has been written on climate change and its impact on health, but little attention has focused on the realpolitik of how to progress the development and implementation of health-relevant strategies and policies to reduce this impact. The objective of this paper is to propose three solutions to address current deficiencies: i) strengthening the capacity and understanding of health officials in relation to climate change and health; ii) improving cross-sectoral partnerships with sectors relevant to climate change and health, and iii) identifying organisations influential in the development of climate change mitigation and adaptation strategies and policies, with a view to better target advocacy efforts. Practical examples of each solution are provided. In conclusion, as a steward of public health, the health sector must take the initiative to encourage a cross-sectoral approach that includes capacity development, coupled with an understanding of influential organisations. If this is done effectively, health, social and economic development goals can be reached more efficiently.

Adaptation and mitigation: trade-offs in substance and methods

Adaptation to climate change and mitigation of climate change are policy substitutes, as both reduce the impacts of climate change. Adaptation and mitigation should therefore be analysed together, as they indeed are, albeit in a rudimentary way, in cost-benefit analyses of emission abatement. However, adaptation and mitigation are done by different people operating at different spatial and temporal scales. This hampers analysis of the trade-offs between adaptation and mitigation. An exception is facilitative adaptation (enhancing adaptive capacity), which, like mitigation, requires long-term policies at macro level. Facilitative adaptation and mitigation not only both reduce impacts, but they also compete for resources.     

Mitigation needs adaptation: Tropical forestry and climate change

The relationship between tropical forests and global climate change has so far focused on mitigation, while much less emphasis has been placed on how management activities may help forest ecosystems adapt to this change. This paper discusses how tropical forestry practices can contribute to maintaining or enhancing the adaptive capacity of natural and planted forests to global climate change and considers challenges and opportunities for the integration of tropical forest management in broader climate change adaptation. In addition to the use of reduced impact logging to maintain ecosystem integrity, other approaches may be needed, such as fire prevention and management, as well as specific silvicultural options aimed at facilitating genetic adaptation. In the case of planted forests, the normally higher intensity of management (with respect to natural forest) offers additional opportunities for implementing adaptation measures, at both industrial and smallholder levels. Although the integration in forest management of measures aimed at enhancing adaptation to climate change may not involve substantial additional effort with respect to current practice, little action appears to have been taken to date. Tropical foresters and forest-dependent communities appear not to appreciate the risks posed by climate change and, for those who are aware of them, practical guidance on how to respond is largely non-existent. The extent to which forestry research and national policies will promote and adopt management practices in order to assist production forests adapt to climate change is currently uncertain. Mainstreaming adaptation into national development and planning programs may represent an initial step towards the incorporation of climate change considerations into tropical forestry.     

Tools for developing adaptation policy to protect human health

Anthropogenic climate change is likely to add significant pressure to the determinants of public health, and to current health and social protection measures in high, middle and low income countries. Adaptation strategies within the health sector are being developed to address the multi-dimensional nature of the costs and impacts. We further develop and apply a new generic conceptual framework for development-compatible climate policy planning to evaluate policy options for middle and low income countries that reduce the adverse health effects of climate change. The criteria used for comparative evaluation included economic, environment, social and institutional factors. The proposed framework, incorporating system dynamics, provides a foundation for a decision-analytical approach to support the formulation of robust climate change adaptation policies to protect human health.     

Re-thinking water policy priorities in the Mediterranean region in view of climate change

Water is scarce in Mediterranean countries: cities are crowded with increasing demand; food is produced with large amounts of water; ecosystems demand more water that is often available; drought affects all. As climate change impacts become more noticeable and costlier, some current water management strategies will not be useful. According to the findings of CIRCE, the areas with limited water resources will increase in the coming decades with major consequences for the way we produce food and we protect ecosystems. Based on these projections this paper discusses water policy priorities for climate change adaptation in the Mediterranean. We first summarise the main challenges to water resources in Mediterranean countries and outline the risks and opportunities for water under climate change based on previous studies. Recognising the difficulty to go from precipitation to water policy, we then present a framework to evaluate water availability in response to natural and management conditions, with an example of application in the Ebro basin that exemplifies other Mediterranean areas. Then we evaluate adaptive capacity to understand the ability of Mediterranean countries to face, respond and recover from climate change impacts on water resources. Social and economic factors are key drivers of inequality in the adaptive capacity across the region. Based on the assessment of impacts and adaptive capacity we suggest thresholds for water policy to respond to climate change and link water scarcity indicators to relevant potential adaptation strategies. Our results suggest the need to further prioritise socially and economically sensitive policies.

Development projects for small rural communities in the Brazilian Amazon region as potential strategies and practices of climate change adaptation

Climate scenarios for the Amazon region (Brazil) indicate an increase in temperature and a precipitation decrease, affecting society and economic activities, particularly small-scale rural communities. The research aims to identify, describe and evaluate factors present in sustainable development projects for small rural communities (Type- A Demonstration Projects - PDA and Alternatives to Deforestation and Burnt Projects - PADEQ), already implemented, for recognizing its potential use as strategies for adaptation to climate change for small rural communities in the Amazon region. The researches, concerning fifteen projects in Rondonia, Para and Mato Grosso States, were developed through document analysis, technical visits, and interviews with stakeholders of three projects about the community perception, vulnerability and adaptation capacity. The analysis of documents regarding the potential success of the projects highlights their short history, important in the local context, prospects for continuity, and community participation in decision making. Few activities developed in projects could be associated with climate change adaptation practices. Two strategies and practices are the most important: the social organization and the process of awareness and training of the community, and the diversification of the types and forms of agricultural production. The interviews indicate that adaptation is implemented in projects, but without considering the pressures of climate variability and change. While these projects were not planned in the context of climate change, the greatest role of the projects relates to the strengthening of the already existing adaptation capacity, creating good conditions for incorporation of new strategies and adaptation measures, now clearly associated to the objective to reduce the vulnerability to climate change and variability impacts.     

Enhancing adaptive capacity to climate change: The case of smallholder farmers in the Brazilian semi-arid region

Climate change is one of the main challenges faced by mankind in this century. Although developing countries have little historical responsibility for climate change, they are likely to be most affected by it since they lack resources to cope with or to adapt to its effects. Studies show that the semi-arid northeast region of Brazil – where the country's poorest populations are concentrated – is one of the most vulnerable to climate change and thus likely to suffer its impacts more severely. The present paper addresses these problems by presenting a concrete initiative for strengthening adaptive capacity in the rural community of Pintadas as a first step in the development of a comprehensive methodology to help smallholder farmers in the region adapt to climate change. Based on the project results this paper highlights the integration of development, adaptive capacity and adaptation strategies. Furthermore, the necessity of vulnerability studies and concrete local experiences is highlighted in order to develop adaptation strategies that can alleviate poverty and minimize climate change impacts for the poor.     

Financial adaptation to disaster risk in the European Union

Increasing losses from weather related extreme events coupled with limited coping capacity suggest a need for strong adaptation commitments, of which public sector responses to adjustments to actual and expected climate stimuli are key. The European Commission has started to address this need in the emerging European Union (EU) climate adaptation strategy; yet, a specific rationale for adaptation interventions has not clearly been identified, and the economic case for adaptation to extremes remains vague. Basing the diagnosis on economic welfare theory and an empirical analysis of the current EU and member states’ roles in managing disaster risk, we discuss how and where the public sector may intervene for managing climate variability and change. We restrict our analysis to financial disaster management, a domain of adaptation intervention, which is of key concern for the EU adaptation strategy. We analyse three areas of public sector interventions, supporting national insurance systems, providing compensation to the affected post event as well as intergovernmental loss sharing through the EU solidarity fund, according to the three government functions of allocation, distribution, and stabilization suggested by welfare theory, and suggest room for improvement.
