Item type:Publication, 2017 Coastal El Niño in Peru: an opportunity to analyze the influence of hazard mitigation plans on local resilience(Elsevier, 2021-01-01)This research proposes an ex post methodology for analyzing the influence of Hazard Mitigation Plans in the level of resilience in localities affected by an extreme event. For verifying its applicability, the case of heavy rainfalls of the 2017 coastal El Niño event in Peru is analyzed. The methodology consists of two analysis levels. The first one correlates the quality of existing plans with damages and recovery rapidity. The second analysis level focuses on one sample of the localities selected for performing a deeper qualitative-territorial analysis. The methodology applicability was verified, and we determined that the reduction of direct damages after an event is correlated to the existence of actions such as land use regulation and the structural reinforcement. Moreover, the identification of those responsible for these processes, the verification of possible financing funds and the estimation of intervention costs positively influence on the reconstruction rapidity. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Spatial analysis for water supply in seismic emergencies: The Lima–Callao metropolitan area(Frontiers Media SA, 2024-01-01)In urban areas exposed to high-magnitude earthquakes, the drinking water supply would be severely damaged, and domestic services would be disrupted for a large part of the population in the event of an earthquake. The Lima-Callao metropolitan area in Peru, South America, is expected to experience an 8.8 Mw earthquake, and it is estimated that approximately 90% of the population would not have immediate access to emergency water in the case of such an event. The main objective of this paper is to define criteria for a spatial analysis method to guide the design criteria for an Emergency Water Supply System (EWaSS). Methods: This paper combines territorial, urban resilience and participatory approaches and presents the results of an interdisciplinary research with social impact. Thus, it examines the urban territory at macro-, meso- and micro scales; physical-spatial variables indicating risk levels and possible public spaces to implement the system; and socio-spatial variables regarding the population, risk perception and participation in management to strengthen urban resilience. Normative tools and the Geographic Information System are used to spatialize and systematize quantitative and qualitative information. Results and discussion: The EWaSS is an alternative for safe water supply in a post-disaster situation that would provide immediate and autonomous operation during the first 72 h of the emergency. The results show the physical-spatial and social viability of urbanized areas and the system design criteria that guide local actors in making decisions at the three levels of emergency management.
