Floods and droughts significantly affect agricultural activities and pose a threat to food security by subsequently reducing agricultural production. The impact of flood events is distributed disproportionately among agricultural communities based on their socio-economic fabric. Understanding climate-related hazards is critical for planning mitigation measures to secure vulnerable communities. [...]

Background: Infectious diseases have proven to be among the greatest challenges to life in the Anthropocene era. Their repeated and cyclical occurrences coupled with varying variants, and rapidly changing climatic conditions within this century threaten to take the world back to the “pre-development era” in the absence of corrective measures. We designed a research study to determine the [...]

Assessing Precipitation Trends that may inform Aging Dam Overtopping across the USA

Jeongwoo Hwang, Upmanu Lall

Published: 2023-07-07
Subjects: Civil and Environmental Engineering, Climate, Earth Sciences, Hydrology, Risk Analysis

In many cases, persistent or recurrent synoptic circulation patterns lead to multiple wet days that precede an extreme rainfall event. The joint occurrence of high antecedent rainfall and extreme rainfall defines a compound event that may pose a high risk for overtopping of aging dams. Our novel analysis assesses whether there are significant trends across the conterminous United States (CONUS) [...]

OpenStreetMap for Multi-Faceted Climate Risk Assessments

Evelyn Mühlhofer, Chahan M. Kropf, David N. Bresch, et al.

Published: 2023-06-29
Subjects: Environmental Sciences, Geographic Information Sciences, Risk Analysis

Natural hazards pose significant risks to human lives, infrastructure, and ecosystems, necessitating a comprehensive understanding of climate risks for effective adaptation planning and risk management. However, climate risk assessments mostly focus on economic asset values and infrastructures such as roads and buildings, because publicly available data on more diverse exposures are scarce. The [...]

Global protection from tropical cyclones by coastal ecosystems - past, present, and under climate change

Sarah Hülsen, Robert I. McDonald, Rebecca Chaplin-Kramer, et al.

Published: 2023-06-27
Subjects: Environmental Sciences, Nature and Society Relations, Risk Analysis

Coastal ecosystems have the potential to contribute to disaster risk reduction and adaptation to climate change. While previous studies have estimated the value of current coastal ecosystems for reducing coastal risk, there have been relatively few studies that look at changes in ecosystem service provision, in the past and under climate change. We employ the probabilistic, event-based CLIMADA [...]

Non-structural Flood Mitigation Optimization at Community Scale: Middle Cedar Case Study

Subjects: Civil and Environmental Engineering, Civil Engineering, Engineering, Environmental Engineering, Risk Analysis

Flooding is the leading natural hazard in Iowa and has resulted in billions of dollars of damage to properties and critical infrastructure over the past couple of decades. Land alterations, urbanization, and changing precipitation regimes increase the magnitude and frequency of flood events. Considering the increasing risk, flood mitigation efforts are significant to reduce future losses. In this [...]

Strategic Logic of Unilateral Climate Intervention

Subjects: Atmospheric Sciences, Climate, International and Area Studies, Other Statistics and Probability, Risk Analysis

Climate change and unabated greenhouse gas emissions are increasing the possibility that the world will turn to climate intervention to curb ever-increasing global temperatures. To date, most work on this topic has imagined that an international organization like the United Nations or an international coalition of states will synchronize their efforts to deploy climate intervention at ideal [...]

Global multi-hazard risk assessment in a changing climate

Natural hazards pose significant risks to people and assets in many regions of the world. Quantifying associated risks is crucial for many applications such as adaptation option appraisal and insurance pricing. However, traditional risk assessment approaches have focused on the impacts of single hazards, ignoring the effects of multi-hazard risks and potentially leading to underestimations or [...]

Has Tropical Cyclone Disaster Risk Increased in Bangladesh: Retrospective Analysis of Storm Information, Disaster Statistics, and Mitigation Measures

Tropical cyclone (TC) disaster risk has likely increased in Bangladesh since the beginning of the 21st century. It is primarily due to the cumulative impact of rising coastal exposures such as population, insufficient funding to address disaster risks, and ineffective utilization of century-old early warning signals for TC. From 2000 to 2020, the average number of people affected by a Category [...]

Fire from volcanic activity (FFVA) is a highly dangerous and largely understudied hazard arising from volcanic activity. FFVA can be caused by a variety of volcanic hazards and can greatly compound the damage and losses associated with volcanic activity, in addition to creating complications for event response and mitigation. In this study, we develop a FFVA ignition probability model underpinned [...]
