气候风险对中国农业经济发展的影响——异质性及机制分析

科学评估气候风险的经济影响是管理气候风险的第一步。本文利用气象站数据和各地区农业经济数据,实证分析了气候风险对我国农业经济发展的影响,并重点分析了该影响的异质性和相关机制。结果显示,气候风险较高地区的农业经济发展要显著慢于其它地区,且该结果在多种模型设定下以及不同衡量变量下都保持一致。异质性分析表明,气候风险对同一地理区域内人均收入水平较低地区的影响更加显著;对农业保险保障水平较高或农业现代化水平较高地区的影响则较小,说明农业保险的发展和农业现代化水平的提高可以降低气候风险对农业经济的负面影响。机制分析表明,从农业投入和产出关系来看,气候风险直接作用于农业经济产出,而非通过影响投入再作用于产出;从气候风险和自然灾害关系来看,气候风险会通过增加自然灾害严重程度对农业经济发展产生不利影响,同时也会直接对农业经济造成负面影响。本文研究为管理气候风险、促进现代农业经济发展和保障粮食供给安全提供了有益启示。

Natural hazards have become increasingly frequent in the Philippines, making the determination of risks associated with large-scale natural hazards and disasters in this area increasingly important. This study developed a method for estimating the risk of disasters from multiple hazards in this country at the province level. The locational probability and consequences of five natural hazards were analyzed over a 30-year period (1982–2011), and the disaster-risk potential of provinces was estimated based on the combined damage cost per capita from five hazards over that period. Information from the Center for Research on the Epidemiology of Disasters Emergency Disasters Database (CRED-EMDAT) was used to analyze the areas and populations affected, damage costs, and frequency and duration of five hazards (i.e. meteorological, climatological, hydrological, geophysical, and biological). The estimated values were then presented spatially using a geographic information system. The results suggested that meteorological hazards were the most common hazards affecting most provinces in the Philippines, whereas hydrological hazards produced the most damage. Small island provinces and coastal zones were among the areas with the highest disaster-risk potential. This assessment can aid in decision making with regard to financing disaster prevention schemes and in planning for the increasing occurrences of natural hazard-related disasters.     

农业自然灾害对通货膨胀的影响——基于动态面板的实证分析

通过将农业自然灾害作为外生冲击引入"三角"模型,建立涵盖通货膨胀惯性、超额需求和农业自然灾害外生冲击三者关系的动态面板模型进行实证分析,结果表明:就全国范围和中部地区而言,农业自然灾害对我国通货膨胀具有明显的影响,而东部和西部地区表现不显著。值得关注的是,农业自然灾害会造成当期通货膨胀水平下降,表明农业自然灾害造成的需求负向冲击大于供给负向冲击,政府相关部门应重视农业自然灾害引起的需求抑制作用。

Revealing global hot spots of technological disasters: 1900–2013

Technological disasters can happen in any country in the world and cause human fatalities, injuries, and economic damages, among other physical and social consequences. As the world adopts more technologies, becomes further industrialized, continues faster urbanization, and has larger and more concentrated population, the occurrences and impacts of technological disasters are likely to be more frequent and severe and call for more scholarly research. However, there is a lack of good models for reliable technological risk analysis, which is the foundation for effective preparation for, sound mitigation of, and quick recovery from technological disasters. This research develops an expected risk analysis model, including a base sub-model and a location quotient sub-model, for nearly 200 countries of the world, using the technological disasters recorded in the EM-DAT database for the period 1900–2013. The sub-models are based on country-level risk impacts in terms of expected fatalities, injuries, people affected, and economic losses, their standard deviations, ranges, and corresponding country percentages and ranks. The sub-models are validated using correlations and scatter plots for the observed and expected risk impacts. The results show that the sub-models perform well by yielding consistent expected risks and related measures, indicating that the expected risk analysis model is a reasonably good alternative to existing risk analysis models.     

Risk cultures and dominant approaches towards disasters in seven European countries

This paper builds upon the risk culture concept started with Mary Douglas’ and Aaron Wildavsky’s seminal work on risk and culture. Based upon the empirical results of a qualitative sociological study on sociocultural factors affecting risk perception and crisis communication in seven European countries, a theoretical model, illustrating how differences in disasters framing imply diverse approaches to risk and disaster management, is suggested. According to this framework, culturally bounded assumptions and conventions strongly influence how communities make sense of risks and hazards and how these communities consider some ways of dealing with disasters more appropriate than others. The framework suggested in this article distinguishes between risk cultures of a given society, which do not necessarily respond to nation states. In order to explain differences in how cultures deal with risks and disasters, and to define the main features of our typology, three main interrelated dimensions have been selected: disaster framing, trust in authorities and blaming. By analyzing differences and similarities in how people perceive and interpret disasters, as well as to whom the responsibility for risk prevention and crisis management is attributed, in seven European countries, three specific ideal types of risk cultures emerged: state-oriented risk culture, individual-oriented risk culture and fatalistic risk culture. Implications for crisis management and communication in case of a disaster will be addressed for each of these risk cultures.     

Schöne Aussicht auf den Fluss? Wahrnehmung von Risiken aus Naturkatastrophen

Impacts of natural disasters have increased worldwide during the last decades. Facing the growing losses from natural hazards also in Germany, the question emerges how persons in likely affected areas perceive risks from natural hazards such as windstorm, flood, and earthquake. The everyday, ?intuitive“ perception of risks is basic for the individual, subjective assessment of natural risks. Consequently, perception and evaluation of risk is basic for behaviour in dangerous situations. It is also fundamental for decisions concerning preventive protective measurements. To be able to develop effective information and communication strategies and politics about natural risks, the perception and evaluation of these risks and influencing factors should be known. Therefore, the purpose of the study presented in this paper is to focus on the perception of storms, floods, and earthquakes and to study factors that influence risk perception. To study risk perception, a mail survey was conducted in summer 2001 in six regions of Germany which had been affected by windstorm, flood and / or earthquake within the last 30 years. Köln-Rodenkirchen, Passau, Karlsruhe, Neustadt/Donau, Albstadt and Rosenheim were selected as survey areas. In total, 450 persons responded the questionnaire. In the study a mixture of approaches to risk perception was applied, among them the psychometric paradigm. The project was conducted at the Institute for Insurance, Universität Karlsruhe (TH) and additionally funded by the Stiftung Umwelt und Schadenvorsorge der SV Versicherungen. The results show that storm, flood, and earthquake are rated heteroge-neously regarding their general dangerousness, several risk characteristics and attributions of causes. Personal characteristics, such as age, education level, and the experience of damage seem to play a role for the general risk rating. In addition, the risk perception of homeowners and tenants differs.     

Determinants of stakeholders’ attitudes towards a new technology: nanotechnology applications for food,water, energy and medicine

Stakeholder risk and benefit perceptions and attitudes towards a technology matter for the societal response to these technologies. This is especially the case for technological innovations where the public has no direct experience with the technology and its applications. In such cases, expert views are the main source for public opinion formation. Stakeholder risk and benefit perception, and their effect on attitudes towards a new technology (nanotechnology) and its applications were examined in two studies. In a survey, the effect of risk and benefit perception on attitudes to nanotechnology in specific application domains (energy, water, food and medicine) was examined. While risk and benefit perception predicted much of the variance in attitude, experts were more positive about medicine applications and more negative about food applications than could be explained through risk and benefit perception. In the second study, expert focus groups were asked for reasons why food and medicine were seen as more negative and positive than based on the risk and benefit perceptions as measured in the survey. For medicine, the urgency and unique potential of nanotechnology was seen as a reason as why this domain was liked more. For food, the high level of uncertainty about risk assessment and about exposure of consumers and the lack of urgency in applying nanotechnology to food was seen as a reason this domain was liked less. In addition, experts voiced concern about potential negative public response to food applications as reasons for their negative attitude. These results thus suggest that both risk and benefit perception consist of multiple dimensions that require further exploration.     

Perceptions of pre-service teachers on seismic risk and their implications for science education: a comparative study between Spain and Portugal

Abstract

This study investigated the importance given by two groups of pre-service teachers of primary education from Spain and Portugal to seismic risk in a framework of different natural risks, both in personal terms and as future teachers. A questionnaire was used for data collection. Some questions about the seismic phenomenon were also included. The sample groups consisted of 110 students from an institution in Spain and 121 from one in Portugal. Both institutions are in cities affected by the historic Lisbon earthquake of 1755. The results showed that the risk of forest fire was the first choice for classroom study in both cases. The Spanish group was also more focused on the importance of other risks like flood and drought. The Portuguese group showed a greater concern with seismic risk, frequently referring to their own historic earthquake of 1755. A few gaps in knowledge concerning earthquake prediction and comparing seismic risk in different regions of their own countries were also found. In accordance with the results, it is suggested that training courses for primary school teachers should include Disaster Risk Education in Science Education for a better understanding of the impact of various hazards and a greater concern with seismic risk due to its particular features, especially in regions where the seismic pattern is characterized by long seismic cycles with major earthquake episodes.     

A multi-attribute approach to assess homeland security risk

The United States Department of Homeland Security manages a wide spectrum of risks involving crime, terrorism, accidents, and natural disasters. This paper supports disaster management by identifying which attributes should be used to describe risks comprehensively and assessing the need to incorporate such multiattribute information into risk management processes. Attributes for describing homeland security risks were selected through a literature review. These attributes were then used in a risk assessment of homeland security hazards that informed risk ranking sessions conducted with members of the general public. The results taken together support the use of a range of attributes and perspectives. While aspects of life/health and economic damage were considered most important by both experts and the lay public, other attributes were of widespread importance, including attributes related to dread and uncertainty. These results demonstrate how to present risks in a deliberative risk management process and the importance of doing so using a complete set of attributes to describe the risks.     

Imagining worse than reality: comparing beliefs and intentions between disaster evacuees and survey respondents1

We often credit disasters, and their coverage in the media, with changes in the public perception of risk associated with low-probability, high-consequence events (LPHCs). With a change in perceptions, we also expect changes in beliefs, preferences, and behaviors. Do beliefs and behaviors change in different ways for people who live through these LPHC critical events, as opposed to people who observe them? This study compares hypothetical hurricanes with actual hurricane effects in a survey quasi-experiment. Findings indicate that hypothetical disasters induce stronger reactions than those experienced in the natural world, as Hurricane Katrina bystanders imagine themselves incurring much higher damages, and being much less likely to return to live in their hurricane-damaged homes, than actual Hurricane Katrina evacuees. Ultimately, respondents considering a hypothetical low-probability, high-consequence event exhibit exaggerated beliefs and opposite decisions of those who actually lived through one of these events. Results underline the importance of examining the differences between public perceptions and experiential reality.     

A composite indicator model to assess natural disaster risks in industry on a spatial level

In the event of natural disasters, industrial production sites can be affected by both direct physical damage and indirect damage. The indirect damage, which often exceeds the direct ones in value, mainly arises from business interruptions resulting from the impairment of information and material flows as well as from domino effects in interlaced supply chains. The importance of industry for society and the domino effects often result in severe economic, social, and environmental consequences of industrial disasters making industrial risk management an important task for risk managers at the administrative level (e.g. civil protection authorities). Since the possible industrial disaster damage depends not only on hazard and exposure but also on the vulnerability of a system, an effective and efficient industrial risk management requires information about the system’s regionalized vulnerability. This paper presents a new methodology for structural industrial vulnerability assessment based on production factors that enables to assess the regional industrial disaster vulnerability. In order to capture industry-specific vulnerability factors and to account for the processes underlying regional industrial vulnerability, a two-stage approach is developed. This approach combines a composite indicator model to assess sector-specific vulnerability indices (V_s) with a new regionalization method. The composite indicator model is based on methodologies from the field of multicriteria decision analysis (MultiAttribute Value Theory) and the Decision-Making Trial and Evaluation Laboratory Method is applied to correct the (V_s) for interdependencies among the indicators. Finally, the developed approach is applied to an exemplar case study and the industrial vulnerability of 44 administrative districts in the German federal state of Baden-Wuerttemberg is assessed.

The prospect of online communication in the event of a disaster

In modern society, enormous amounts of information are instantly exchanged, and topics shift rapidly. People desire and share information to foster a sense of membership in their societies. The trend of Internet communication is present in many types of groups. During the circumstances of disasters, the 2011 Great East Japan earthquake and Tsunami and Typhoon Haiyan (local name, Yolanda) in the Philippines in 2013, social networking services (SNS) constituted a considerably effective method for sharing/exchanging information about the significance of the disaster, confirming family members’ and friends’ whereabouts, locating shelters, relief, food and goods rationing, and so on. Not only did individuals seek/provide information, but government agencies also utilized the social media channels to communicate with the public. Hence, developing and adopting communication in a virtual space were considerably effective for decision-makers in providing emergency services. This study examined SNS users’ accounts based on discretionary decisions during two major disasters: the Great East Japan Earthquake and Tsunami in 2011 and Typhoon Haiyan in the Philippines in 2013. In the case of the Great East Japan Earthquake and Tsunami in 2011, government agencies and NPOs actively utilized SNS functions, whereas the mass media distributed information during Typhoon Haiyan in the Philippines in 2013.

自然灾害对经济增长影响研究 ——基于制度、政府救灾支出的调节视角

基于2007-2018年中国省际面板数据,运用动态系统广义矩模型(GMM),考量制度、政府救灾支出在调节自然灾害对经济增长影响方面的作用.结果表明:从全样本来看,政府救灾支出有利于增强自然灾害对经济增长的促进作用,自然灾害对经济增长的影响受制度的影响较小.分经济区域来看,政府救灾支出有利于增强自然灾害对东部和西部经济增长的促进作用,但对东北地区产生抑制作用;制度可以缓解东部自然灾害对经济增长的抑制作用,但阻碍西部自然灾害对经济增长的促进作用.进一步分析发现,救灾支出、制度在调节自然灾害对经济增长的影响时,都存在倒U型非线性关系.     

环境灾害冲击对银行违约率的影响效应研究:理论与实证分析

本文通过模型模拟和基于中国数据的实证检验,分析了环境灾害损失冲击对于银行违约率的影响。本文模型模拟的结果显示,环境灾害冲击会显著提升银行体系的违约率水平,同时伴随着企业融资溢价水平的提升以及整个经济活动的萎缩;实证研究发现:环境灾害损失冲击会导致银行违约率水平显著提升。且与理论分析一致,本文实证发现宏观经济不确定性水平、企业的资本折损以及全要素生产率的下降在环境灾害影响银行违约率的过程中发挥了显著的传导作用。进一步研究发现,环境灾害冲击及其导致的银行违约率上升还会降低银行的风险偏好水平,降低放贷规模和主动风险承担,并反作用于实体企业,提升企业的融资约束和成本。本文的研究结论丰富了基于中国视角的环境物理风险研究,刻画了环境灾害损失对于银行风险的影响及其后续效应,为政策部门防范气候环境风险提供了借鉴。     

Benchmarking Risk Management Within the International Water Utility Sector. Part II: A Survey of Eight Water Utilities

Risk management in the water utility sector is fast becoming explicit. Here, we describe application of a capability model to benchmark the risk management maturity of eight water utilities from the UK, Australia and the USA. Our analysis codifies risk management practice and offers practical guidance as to how utilities may more effectively employ their portfolio of risk analysis techniques for optimal, credible, and defensible decision making. For risk analysis, observed good practices include the use of initiation criteria for applying risk assessment techniques; the adoption of formalised procedures to guide their application; and auditing and peer reviews to ensure procedural compliance and provide quality assurance. Additionally, we have identified common weaknesses likely to be representative of the sector as a whole, in particular a need for improved risk knowledge management and education and training in the discipline.     

地理分散化降低了多少保险经营风险?

本文定量分析了地理分散化对中国保险公司经营风险的影响。收集我国1998~2017年间各省市区的财产保险业和人身保险业的收入和支出数据,基于投资组合原理,比较了三种地理布局战略下保险公司的赔付风险。研究发现:无论是财产保险业还是人身保险业,各省区市之间赔付风险的差异性较大,在华北、东北、华东、中南、西南和西北这六大区域内部经营并不能显著地分散风险,但扩大到全国范围内经营,便能够较好地分散风险。进一步,采用Bootstrap随机模拟方法分析发现:财产保险公司在约10个省区市经营能够分散掉约80%的赔付风险,而人身保险公司在约5个省区市经营能够分散掉约40%的赔付风险。鉴于财产保险公司经营的各条产品线之间的风险差别较大,本文还发现:农业保险的地理分散化效果最强,短期健康险的地理分散化效果最弱。研究结果既支持保险公司跨地域经营以降低风险,也为监管资本设计中考虑地理分散化效应提供了经验证据。     

Public sector risk managers and spending cuts: mitigating risks

This paper reports case study research, the results of which are used to consider whether councils have recognised the potentially substantially increased social risks they may create as they seek to reduce their spending in line with the UK Government’s programme of public sector austerity. It discusses the conceptual shift in the public sector risk management literature towards social risk management (SRM), presents empirical evidence of social risks and considers the approach to SRM developed by other organisations. It finds no evidence of SRM within the case study authorities and so advocates a shift in the public sector risk management culture from a preoccupation with defensive-institutional risk management practices to a more proactive social dimension. In so doing, it discusses the goals of SRM, the constraints limiting their achievement, metrics for measuring social risk, tools for mitigating social risk and the problems faced when operationalising SRM.
