This paper addresses the problem of interdependent failures of critical infrastructures in disasters. Disruptions to critical
infrastructure systems such as electric power or transportation frequently cause major social and economic loss in disasters,
both directly and through failures in one system leading to or compounding disruptions in another. Strategic approaches regarding
infrastructure failures are needed to guide community mitigation and preparedness efforts. This paper defines and provides
a conceptual framework for investigating infrastructure failure interdependencies (IFIs) from the standpoint of societal impacts.
In order to identify empirical patterns, a unique database has been developed of IFIs observed in major electric power outage
events. This paper presents analysis of this data for a major Canadian disaster, the 1998 Ice Storm that affected the northeastern
region of the country. The analysis identifies IFIs due to power outage caused by the storm that are of greatest societal
concern. These represent potential foci for effective, targeted pre-disaster mitigation and preparedness efforts. The framework
and approach are broadly applicable across a range of natural and human-induced hazards. 相似文献
The structural measure was the major solution for flood defense in Taiwan. However, the measure is always limited to the design
standard and cannot prevent the damages when floods exceed certain scale. Therefore, non-structural measures for flood mitigation
are the indispensable complements to structural solutions. The study introduces the establishment of inundation potential
database that provides required information for the non-structural measures in Taiwan. The database was built by numerical
simulations, based on different rainfall scenarios, and has been applied by the local governments of Taiwan for land use managements,
flood warning systems, emergency responses, and flood insurance programs to reduce the flood damages and impacts. 相似文献
This study aimed to evaluate climate mitigation policy packages in various countries’ nationally determined contributions by introducing four intermediate policy goals: decarbonizing energy, improving energy efficiency, reducing demand for energy services, and enhancing carbon sinks and reducing emissions of non-CO2 gases. The methodology was examined by using data of China, Germany, Japan, the UK, and the US. Climate mitigation policies introduced between 1990 and 2015 in the five countries were categorized into four intermediate policy goals. Six indicators were introduced to measure actual outcomes, each representing one of the four intermediate policy goals. A comparison between the policy categorizations and the indicator outputs led to the conclusion that the number of policies implemented partially reflects the countries’ efforts to achieve specific policy goals, even though the stringency of each policy was not taken into account. This comparison was also useful in identifying key policies that were effective in achieving policy goals, even if there was a relatively small number of policies. The methodology was useful in generating policy recommendations to fulfil all the four intermediate goals in a balanced manner.
POLICY RELEVANCE
The Paris Agreement, adopted at the 21st Conference of the Parties to the United Nations Framework Convention on Climate Change (COP21) in December 2015, calls for all countries to prepare, communicate, and maintain successive nationally determined contributions (NDCs) and pursue domestic mitigation measures with the aim of achieving the objectives of such contributions (Article 4.2). Under this new regime, methodologies to assess policy implementation have become increasingly important, especially for the post-2020 period. The methodology developed in this study is simple enough for any country to use and was effective in grasping the overall characteristics of the climate mitigation policy package in each country or region studied. The study recommends that the UNFCCC create a rule requesting countries to submit estimates of population, GDP, total energy demand, share of renewables, and other relevant factors for the target year when they submit their successive intended NDCs. 相似文献
In September 2018, leaders in climate action within and outside the U.S. will convene in San Francisco for the Global Climate Action Summit. They plan to demonstrate strong ongoing commitment to exceeding the goals set out in the Paris Agreement, despite U.S. federal opposition under President Trump, and to spur greater ambition among subnational governments and the private sector. Now that the Trump Administration is working to undo the progress made under President Obama, it is more important than ever that states and cities, as well as the private sector, redouble their efforts. Since the 2016 election, many U.S. states have demonstrated leadership by establishing ever-more ambitious clean energy and electric vehicle targets through legislation and executive action; by pushing back on the Trump Administration in public forums and in the courts; and by banding together to realise greater effectiveness through collective action. The commitment of leading states, cities, and businesses alone will not be enough to achieve the rapid reductions needed to keep planetary warming to 1.5 degrees C in the absence of U.S. federal efforts. But coming after a summer of extreme weather events, the Summit represents a critical opportunity to re-energise constituencies, highlight the need for urgent and ambitious action, and bring climate change to the forefront of policy conversations across the U.S. and beyond.
Key policy insights
The reversal of U.S. ambitious clean energy and transportation policy, including replacing the Clean Power Plan, freezing fuel standards, and withdrawing from the Paris Agreement, have created a gap at the federal level under President Trump that will be difficult – but perhaps not impossible – to fill with subnational action.
States, local governments, and the private sector have shown a strengthened commitment to combating climate change and to the goals set out in the Paris Agreement through more ambitious legislative and executive targets, and regional initiatives like RGGI and cross-jurisdictional zero emissions vehicle programmes.
The Global Climate Action Summit in September 2018 is a pivotal moment to energise a broader coalition within and outside the U.S. towards catalysing the level of ambition needed to exceed goals set out in the Paris Agreement.
This article is a case study of the Mitigation Action Plans and Scenarios programme (MAPS) which worked in climate change mitigation and development policy-making spaces in Brazil, Chile, Colombia, Peru and South Africa from 2010–2015. The MAPS programme was focused on achieving change in the commitment of southern decision makers to mitigate against climate change through government-mandated, stakeholder processes which generated evidence making a case for a low carbon transition. The article draws on reflective materials generated in the last year of the project. The value of MAPS was found in the well-tested data and evidence-driven scenario building; locally specific and country-driven processes; a culture of knowledge sharing through facilitated communities of practice; the role of professional facilitation in process design and in conducting stakeholder processes; shared experiences of working in the south, and particularly with cultural differences and conflict; and new ways of working south–south with each other, and with donors. These MAPS programme experiences stood in contrast to previous north–south knowledge sharing involvements. Theoretically, the article asks whether MAPS represents southern theory-making (after Connell, 2007). It concludes that through the action-oriented, facilitated co-production way of working on climate change in the south, MAPS represents an understanding of southern theory that challenges the orthodoxy of global knowledge production. MAPS emphasizes the need for theorizing in, and of, the south, and connecting policy and practices.
Key policy insights
Climate change mitigation work in the south faces poorly resourced, fragmented, under-capacitated governance structures, often in conflicted settings.
Given conflicted settings, skilled facilitation is an integral part of knowledge-making processes.
Strong local communities of practice, who undertake learning-by-doing and are connected to ‘stubborn’ development realities, are also key to knowledge-making.
Intentional co-production of data and evidence enable peer-to-peer learning and the trust-building which is vital to strong communities of practice.
Following the 1938 hurricane that damaged much of the New England coast, New London, Connecticut, responded like most communities by leveraging federal and state funds to rebuild and augment engineered mitigation structures. Eighty years of subsequent storm experience, however, illustrates that a small number of nonstructural mitigation projects, especially private property acquisitions, have had significant long-term effects on New London's coastal resiliency, especially in the Ocean Beach neighborhood. Archival research identifies that these nonstructural mitigation projects were not initially intended to reduce hurricane or flooding risk but were aimed at removing structures determined to be public nuisances and reducing fire hazard. Therefore, New London's post-1938 mitigation experience underscores how community-scale mitigation planning following one disaster can greatly affect the outcome of future disasters. Analytically, New London's experience offers a compelling case study to critically compare two competing environmental mitigation approaches following the same disaster and to offer insight into the environmental legacies of both. 相似文献
