Seismic fragility assessment provides a substantial tool for assessing the seismic resilience of these buildings. However, using traditional numerical methods to derive curves poses significant challenges. These often overlook diverse range buildings found in different regions, as they rely on standardized assumptions and parameters. Consequently, may not accurately capture response various building types. Alternatively, extensive data collection becomes essential address this knowledge gap by understanding local construction techniques identifying relevant This is crucial developing reliable analytical approaches that can curves. To overcome challenges, research employs four Machine Learning (ML) techniques, namely Support Vector Regression (SVR), Stochastic Gradient Descent (SGD), Random Forest (RF), Linear (LR), probability collapse terms Peak Ground Acceleration (PGA). achieve objective, comprehensive input/output dataset consisting on-site collected from 646 masonry walls Malawi used.

Over recent years, and as a result of the global health pandemic, resilience has become increasingly central to contemporary policy discourses in urban planning development both Global North South. Drawing from ongoing empirical studies community everyday practices that have been co-designed co-produced alongside Brazilian marginalised communities which are highly vulnerable range natural hazards, this paper highlights growing importance dialogical stakeholder engagement methodologies designing alternative visions – so-called imaginaries or counter-cities - across South based on social diversity, equity spatial justice. More specifically, participatory mapping approach outlined utilises citizen science approaches develop local imaginaries, building pedagogical work educator Paulo Freire conceptualisation dialogue comprehensive progressively unfolding methodological approach. Practically, we adopted allowed citizens more aware their own risk context embed tacit knowledge into operation civil protection programmes. Our results highlight potential such capture lay contribute enhanced approaches. The concludes by reflecting role formerly voices advancement novelty promise critical co-production within existing regimes governance imagining radically independent counter-cities.

International Journal of Disaster Risk Reduction, Journal Year: 2024, Volume and Issue: 111, P. 104710 - 104710

Published: Aug. 3, 2024

Disaster preparedness and response, including for landslides, increasingly involves local knowledge. Incorporating contextual, dynamic experience-based knowledge leads to greater awareness of the interconnectedness geological, natural, social processes. Still, technical literature on urban landslide risk is mainly based geological natural dynamics and, a lesser extent, physical infrastructure. Moreover, although recognized as important in principle all aspects disaster management, it not frequently taken starting point identifying contextually specific factors practice. To gain insights into contributing risk, we conducted qualitative case study within landslide-prone informal settlement Manado, Indonesia. The comprised household interviews, transect walks, ethnographic observation. Our findings indicate that anthropogenic settlements, particularly inadequate solid waste may serve an overlooked factor landslides. This especially problematic low-income or neighborhoods, where detrimental effects poor management intersect with heightened vulnerability various hazards. We therefore advocate systematically incorporating studies Additionally, encourage further research interactions between risk.

ABSTRACT The present study aimed to identify and prioritize people's participation barriers (PPBs) in watershed intervention projects (WIPs), considering the perspectives of both experts local people Dastgerd watershed, Iran. Thirteen important PPBs implementation WIPs were identified study. findings indicated that a lack participatory guidelines, an expert-oriented decision-making process, deficiency economic incentives during constituted most crucial PPBs. In addition, according two-sample KS test, there is significant difference two groups regarding importance 60% biggest differences observed concerning `ignoring benefit from project' `lack consultation attention their suggestions'. Given substantial impact expert opinions on policy-making watersheds, any misconceptions they hold for can lead adverse outcomes planning soil water conservation projects. To address this issue, establishment think tanks facilitation brainstorming sessions play pivotal role fostering mutual understanding, aligning experts, making informed decisions overcome challenges.
