Mitigation of urban vulnerability through a spatial multicriteria approach: In Disaster Advance, Vol. 5 (3), July 2012
This study aims to address seismic risk management and how it is generally carried out through strategies aiming to reduce seismic vulnerability in buildings, to enhance structural features, and to reduce vulnerabilities in the whole urban system. It also addresses how resilience becomes strategic in preparing for post-emergency phases and how resilience is strategic to managing seismic risk and reducing urban vulnerability. It presents results from tests conducted in southern Italy which considered closeness to urban centers, map of seismic hazard, and seismic vulnerability of buildings.

The work book is designed to provide a user-friendly, step-by-step approach to national, provincial and local planning. It is argued that the potential impacts of natural disasters and climate change should be considered in nearly every aspect of urban planning and development.
Climate change, disaster risk, and the urban poor: cities building resilience for a changing world
Baker Judy L. - World Bank, 2012This study study examines the inter linkages between climate change, disaster risk, and the urban poor. This study calls on cities to take a lead role in proactively addressing the risks of climate change and natural hazards at the local level, with a focus on populations at highest risk. It suggests a number of actions that cities can take to build resilience, beginning with mainstreaming pro-poor risk reduction policies into urban planning and management.
How to make cities more resilient: a handbook for local government leaders
UN/ISDR, 2012This handbook provides mayors, governors, councillors and other local government leaders with a generic framework for risk reduction and points to good practices and tools that are already being applied in different cities for that purpose. It discusses why building disaster resilience is beneficial; what kind of strategies and actions are required; and how to go about the task. It offers practical guidance to understand and take action on the "Ten Essentials for Making Cities Resilient" as set out in the global campaign "Making Cities Resilient: My City is Getting Ready!".

Analysis on the impact of aerosol optical depth on surface solar radiation in the Shanghai megacity, China
Atmospheric Chemistry and Physics (ACP), Vol. 11. N° 7. Xu J.; Li C.; Shi H.; et al. - Copernicus GmbH, 2011This study investigated the decadal variation of the direct surface solar radiation (DiSR) and the diffuse surface solar radiation (DfSR) during 1961–2008 in the Shanghai megacity as well as their relationships to Aerosol Optical Depth (AOD) under clear-sky conditions. Three successive periods with unique features of long term variation of DiSR were identified for both clear-sky and all-sky conditions: a "dimming" period from the late 1960s to the mid 1980s, a "stabilization"/"slight brightening" period from the mid 1980s to the mid 1990s, and a "renewed dimming" period thereafter. During the ...

Impact of model grid spacing on regional- and urban- scale air quality predictions of organic aerosol
Atmospheric Chemistry and Physics (ACP), Vol. 11. N° 7. Stroud C.A.; Makar P.A.; Moran M.D.; et al. - Copernicus GmbH, 2011Regional-scale chemical transport model predictions of urban organic aerosol to date tend to be biased low relative to observations, a limitation with important implications for applying such models to human exposure health studies. We used a nested version of Environment Canada's AURAMS model (42- to- 15- to- 2.5-km nested grid spacing) to predict organic aerosol concentrations for a temporal and spatial domain corresponding to the Border Air Quality and Meteorology Study (BAQS-Met), an air-quality field study that took place in the southern Great Lakes region in the summer of 2007. The use o ...

Insights into the secondary fraction of the organic aerosol in a Mediterranean urban area: Marseille
Atmospheric Chemistry and Physics (ACP), Vol. 11. N° 5. El Haddad I.; Marchand N.; Temime-Roussel B.; et al. - Copernicus GmbH, 2011A comprehensive aerosol characterization was conducted at Marseille during summer, including organic (OC) and elemental carbon (EC), major ionic species, radiocarbon (14C), water-soluble OC and HULIS (HUmic LIke Substances), elemental composition and primary and secondary organic markers. This paper is the second paper of a two-part series that uses this dataset to investigate the sources of Organic Aerosol (OA). While the first paper investigates the primary sources (El Haddad et al., 2010), this second paper focuses on the secondary fraction of the organic aerosol.

Primary sources of PM2.5 organic aerosol in an industrial Mediterranean city, Marseille
Atmospheric Chemistry and Physics (ACP), Vol. 11. N° 5. El Haddad I.; Marchand N.; Wortham H.; et al. - Copernicus GmbH, 2011Marseille, the most important port of the Mediterranean Sea, represents a challenging case study for source apportionment exercises, combining an active photochemistry and multiple emission sources, including fugitive emissions from industrial sources and shipping. This paper presents a Chemical Mass Balance (CMB) approach based on organic markers and metals to apportion the primary sources of organic aerosol in Marseille, with a special focus on industrial emissions. Overall, the CMB model accounts for the major primary anthropogenic sources including motor vehicles, biomass burning and the a ...

Three-year ground based measurements of aerosol optical depth over the Eastern Mediterranean: the urban environment of Athens
Atmospheric Chemistry and Physics (ACP), Vol. 11. N° 5. Gerasopoulos E.; Amiridis V.; Kazadzis S.; et al. - Copernicus GmbH, 2011Three years (2006–2008) of ground-based observations of the Aerosol Optical Depth (AOD) in the urban environment of Athens, in the Eastern Mediterranean, are analysed in this work. Measurements were acquired with a Multi-Filter Rotating Shadowband Radiometer at five wavelengths. The daily average AOD at 500 nm is 0.23, and the mean Ångström coefficient calculated between 415 and 867 nm is 1.41. The annual variability of AOD has a spring maximum dominated by coarse dust particles from the Sahara (AOD 0.34–0.42), while the diurnal pattern is typical for urban sites, with AOD steadily increasing ...
