Abstract Flooding is among the most prevalent natural hazards, with particularly disastrous impacts in low-income countries. This study presents global estimates of number people exposed to high flood risks interaction poverty. It finds that 1.81 billion (23% world population) are directly 1-in-100-year floods. Of these, 1.24 located South and East Asia, where China (395 million) India (390 account for over one-third exposure. Low- middle-income countries home 89% world’s flood-exposed...

Transport network criticality analysis aims at ranking transport infrastructure elements based on their contribution to the performance of overall network. Despite wide variety metrics, little guidance is available selecting metrics that are fit for specific purpose a study. To address this gap, study reviews, evaluates and compares seventeen metrics. First, we conceptually evaluate these in terms functionality system try represent (either maintaining connectivity, reducing travel cost, or...

To prevent floods from becoming disasters, social vulnerability must be integrated into flood risk management. We advocate that the welfare of different societal groups should included by adding recovery capacity, impacts beyond-design events, and distributional impacts. This Comment advocates

Transport network criticality analyses aim at identifying important segments in a transport network. Such studies are often based on the utilitarian principle, where of segment is assessed its contribution to aggregate performance system. To allow for use alternative moral principles, I systematically operationalize concepts from equity literature into an equity-based analysis framework. There two main ideas this framework: calculation equity-weighted demand distributive principles and...

Mangroves have been used for coastal protection in Bangladesh since the 1960s, but their integration with embankment designs has not fully explored. This paper investigates effect of existing mangroves on required performance, a focus wave-damping mangroves. Existing reduce thickness revetment by up to 16–30% west, 47–82% central region, and 53–77% east. Notable mangrove sites include belt south polder 45 (Amtali), an average width 1.77 km, Kukri-Mukri polder, 1.82 km. These need thick slope...

To support equitable planning, model-based analyses can be used to explore inequality patterns arising from different scenarios. Scenario discovery is increasingly extract insights ensembles of simulation. Here, we apply two scenario approaches for unraveling and their drivers, with an application spatial farms profitability in the Vietnam Mekong Delta. First, follow established sequential approach where begin clustering simulation results next identify model input subspaces that best...

Abstract The need for explicitly considering equity in climate change adaptation planning is increasingly being recognized. However, evaluations of often adopt an aggregated perspective, while disaggregation results important to learn about who benefits when and where. A typical example rice agriculture the Vietnam Mekong Delta (VMD). Efforts focused on flood protection have mainly benefitted large‐scale farmers harming small‐scale farmers. To investigate distributional consequences policies...

Abstract Flooding is among the most prevalent natural hazards, with particularly disastrous impacts in poor countries. Presenting first global estimates of number people exposed to high flood risks interaction poverty, this study finds that 1.81 billion (23% world population) are directly 1-in-100-year floods.

Abstract To support equitable adaptation planning, quantitative assessments should consider the fairness of distribution outcomes to different people. What constitutes a fair distribution, however, is normative question. In this study, we explore use moral principles drawn from theories distributive justice evaluate fairness. We planning in Vietnam Mekong Delta as case study. preference ranking six alternative policies for seven across an ensemble scenarios. Under baseline scenario, each...

Integrated assessment models often treat land-use change as an external driving force. In reality, is influenced by environmental conditions. This paper explores the merits of endogenising change, i.e. making a dynamic internal process, in used for supporting climate adaptation planning. For this purpose, we extend Waas model, hypothetical case study before testing new model-based approaches. We use utility-based model dynamics, evaluate its implications, and identify conditions under which...

Transportation plays a pivotal role in society the accessibility of socio-economic functions, such as education and health services. At same time these transport networks are put under pressure due to increasing demands often-increasing occurrence climate-induced events. To increase resilience transportation network disruptions, criticality has been used prioritise segments for interventions. Here we present how equity principles can be applied context decision making resilient...

To prioritise transport interventions, network criticality analysis is often conducted using a utilitarian principle that seeks to maximise benefits for all. This moral perspective does not account inequalities exist among different population groups. Using open-source data, we measure and compare the impact of four equity principles on road in 22 middle- lower-income countries. Among these countries, found significant variations rankings spatial distribution critical links when are used....
