A new methodology for probabilistic flood displacement risk assessment: the case of Fiji and Vanuatu

Frontiers in Climate, Год журнала: 2024, Номер 6

Опубликована: Апрель 17, 2024

This paper presents an enhanced probabilistic flood displacement risk assessment methodology. Several techniques have been proposed to estimate the number of people at being displaced triggered due climatic extremes. Among these methods, approach is promising for its quantitative nature and versatility different scales. However, it has so far limited assessing loss housing as sole cause displacement. The methodology addresses this limitation by considering two additional elements beyond traditional evaluation loss: likelihood losing means livelihood, directly included in computation, access essential services, such schools health centers, provided a factor increase propensity displace. new applied assess disaster Fiji Vanuatu, where climate change, coupled with vulnerability exposed assets, poses existential threat Pacific islands, potentially leading internal cross-border population movements. Different scenarios were considered: current conditions (1979–2016 period), medium-term projected (2016–2060), long-term (2061–2100). average annual increases Vanuatu 3 4, respectively, pessimistic scenario compared conditions.

What is in a number? Some reflections on disaster displacement modelling

International Migration, Год журнала: 2023, Номер 61(4), С. 353 - 357

Опубликована: Июль 17, 2023

Abstract The rise in global displacement has inspired a wave of quantitative comparative research recent years. While deeper systematic knowledge on contextual determinants disaster‐related mobility and associated risks is high demand, modelling human should be exercised with care. In this commentary, I reflect three central challenges related to the quality available statistics. Future scientific progress field would benefit tremendously from harmonization validation data that separate between distinct responses.

Shannon Entropi (SE) ve AHP Metoduyla Artvin (Arhavi) Kapisre Taşkınının İncelenmesi

Yüzüncü Yıl Üniversitesi Fen Bilimleri Enstitüsü Dergisi, Год журнала: 2024, Номер 29(2), С. 611 - 631

Küresel iklim değişikliği etkilerinin giderek daha fazla hissedilmesi ile birlikte, taşkın alanlarının belirlenmesi ve zararlarının azaltılmasına yönelik yapılan çalışmaların önemi de artmaktadır. Bu çalışmada, Artvin ili Arhavi ilçesinin sınırları içerisinde 2021 yılında yaşanan, can mal kaybına neden olan incelenmiş nedenleri ortaya konulmaya çalışılmıştır. Taşkın çalışmalarında sıklıkla kullanılan 9 adet taşkına etki eden parametrelerin yanısıra Çok Kriterli Karar Verme yöntemlerinden AHP Shannon Entropi (SE) metoduyla çalışma sahasının risk haritası çıkarılmıştır. Çalışma sonucunda, her iki metoda göre en etkili parametreler yükselti yağış olarak belirlenmiştir. Taşkının yaşandığı lokasyonların düşük değerleri, yoğun alüvyal toprak tipi özelliği gösterdiği bulguları arasındadır. Ayrıca SE, metotlarıyla havzanın çıkarılmış 4 doğrulama bu metodun doğruluk değerleri hesaplanmıştır. metodu metoduna iyi sonuçlar verdiği tespit edilmiştir.

Floods of movement

Climate change and associated sea-level rise are expected to increase flood risk in many regions, impacting millions of people by impairing human safety causing damage agriculture, properties, critical infrastructure. Migration safer areas is one way for adapt presents an enormous policy challenge given the number affected. The main goal this Thesis conduct novel empirical research better understand factors driving migration different contexts. These insights anticipatory policymaking management flood-induced migration, improving forecasting, guiding vulnerability resilience face climate change. first chapter dissertation a systematic literature review that examines existing (quantitative) on how behavior shaped other rise-related hazards. It reveals finds mixed effects influence flooding migration. Floods sometimes decrease lower-income contexts, possibly due financial resource depletion they cause. also outlines comprehensive agenda future topic. A limitation studies focus past events. Although learning from gives us important insights, dynamics its drivers likely considerably under increased rise. Consequently, we miss solid understanding risk. To address gap fulfill dissertation, second, third, fourth chapters present risk, each contributing their own key gaps literature. In presented these chapters, originally collected household survey data analyzed close 5,000 respondents six countries with varying socio-economic contexts worldwide (Vietnam, Netherlands, Argentina, France, Mozambique United States). Some universal findings found chapters. First, intentions lower lower/middle-income studied than higher-income countries. Second, all researched case studies, scenarios Third, large majority respondents, more 90% countries, report would migrate internally within country borders instead internationally. Fourth, implementation in-situ adaptation measures, another sensible approach households protect themselves against generally (strongly) intentions. three provide specific findings.

Estimating effects of monsoon flooding on household water access

Environmental Research Letters, Год журнала: 2024, Номер 19(9), С. 094038 - 094038

Опубликована: Авг. 8, 2024

The importance of climate in water resources management is well recognized, but less known about how affects access at the household level. Understanding this crucial for identifying vulnerable households, reducing health and well-being risks, finding equitable solutions. Using difference-in-differences regression analyses relying on temporal variation interview timing from multiple, cross-sectional surveys, we examine effects monsoon riverine flooding among 34 000 households Bangladesh 2011 2014. We compare access, a combined measure both source time collection, living flood-affected non-flood-affected districts before after events. find that surveyed had between 2.27 4.42 times higher odds experiencing low access. Separating geographically, while coastal have lower than those non-coastal districts, flood exposure stronger predictor districts. Non-coastal were particularly burdened 2014, when affected by 4.71 also wealth consistent Overall, our results show associated with prevalence access; socioeconomically are especially burdened.

Inference with Extremes: Accounting for Extreme Values in Count Regression Models

International Studies Quarterly, Год журнала: 2024, Номер 68(4)

Опубликована: Сен. 14, 2024

Abstract Processes that occasionally, but not always, produce extreme values are notoriously difficult to model, as a small number of observations may have large impact on the results. Existing methods for handling often arbitrary and leave researchers without guidance regarding this problem. In paper, we propose an value zero-inflated negative binomial (EVZINB) regression which allows separate modeling nonextreme solve The EVZINB model offers elegant solution data with draw additional inferences about both observations. We illustrate usefulness by replicating study effects deployment UN peacekeepers one-sided violence against civilians.
