Copulas for hydroclimatic analysis: A practice-oriented overview


One function that can be used in analyzing the risks of compound events, given their disproportionately high adverse impacts is Copula. This mathematical function expresses the joint cumulative probability distribution of multiple variables.

CNDS Fellow, Faranak Tootoonchi (Uppsala University), together with colleagues worked on emphasizing this function's fundamental requirements and application limitations. The paper makes sure to:

  • "provide end-users with a didactic overview of necessary requirements, statistical assumptions and consequential limitations of copulas,
  • synthesize common perceptions and practices, and
  • offer a user-friendly decision support framework to employ copulas, thereby support researchers and practitioners in addressing hydroclimatic hazards, hence demystify what can be an area of confusion".

Hidden weaknesses within volcanoes may cause volcano collapse


Lava domes form at the top of many volcanoes when viscous lava erupts. When they become unstable, they can collapse and cause a hazard. An international team of researchers has analysed summit dome instabilities at Merapi Volcano, Indonesia. The researchers hope that by understanding the inner processes, volcano collapses can be better forecasted.

Catastrophic volcano collapses and associated explosions, like the famous collapse of Mt St Helens in 1980, are widely considered as unpredictable. This is because the physical properties, stress conditions, and internal structure of volcanoes and the lava domes on top of many volcanoes are not well understood and can change rapidly from one day to another.

In this new study jointly led by Gadja Mata University in Yogyakarta Indonesia, Uppsala University in Sweden, and the German Research Center GFZ at Potsdam, CNDS Fellows, Valentin Troll and Frances Deegan, together with colleagues explain summit dome instabilities and associated pyroclastic flows at Merapi volcano, Indonesia. The study combines novel drone-based photogrammetry surveillance over several years with mineralogical, geochemical, and mechanical rock strength measurements.

The research demonstrated that a horseshoe-shaped fracture zone in the volcanoes summit region that formed in 2012 and which guided intense gas emission in the past was subsequently buried by renewed lava outpourings in 2018. The new lava dome that has been forming since 2018 started to show signs of instability in 2019 and the researchers were able to show that the summit dome of the volcano is currently collapsing along this now-hidden fracture zone. The research team then considered the changes that must have occurred along this now buried fracture zone from long term gas flux by measuring the composition and physical properties along similar fracture zones in the volcano’s summit region, and concludes that weakened rocks of the hidden fracture zone are likely the main cause for the location of the ongoing summit instabilities at Merapi.

This finding now offers an opportunity for monitoring teams at volcanoes to better forecast locations of potential volcano collapse by employing long-term remote sensing monitoring techniques to assess the hazards associated with summit dome and edifice failure and collapses at active volcanoes worldwide.

Two years into the COVID-19 pandemic and eleven years since the Fukushima nuclear disaster


March 11 marks the day of the 2011 Tohoku earthquake and tsunami in Japan that caused thousands of fatalities and the nuclear disaster in Fukushima. On the same day, two years ago, the World Health Organisation (WHO) announced that COVID-19 could be characterized as a pandemic. These two crises are emblematic of how natural hazards and related disasters continue to pose a major threat to societies. Droughts and floods, for example, affect more than 100 million people per year, and cause catastrophic losses in many regions of the world. While we cannot prevent extreme weather events, volcanic eruptions, earthquakes, and pandemics from occurring, societies can become more prepared and reduce vulnerabilities to mitigate their impacts and reduce losses.

The Centre of Natural Hazards and Disaster Science (CNDS) is an interdisciplinary research centre in Sweden that brings together early career scientists and leading researchers from engineering, social and earth sciences to work together in projects on natural hazards, socio-technological vulnerabilities, and societal security. The vision of the centre is to advance disaster risk reduction and contribute to enhancing society’s ability to prepare for and cope with natural hazard risk in the national and international context.

CNDS is a virtual research centre that was formed in 2010 when the Swedish Government marked natural hazards and disaster science as a strategic research area. Today, CNDS is Sweden’s leading research centre on natural hazards, disaster risk reduction and crisis management, comprising ten departments from three universities (Uppsala University, Swedish Defence University, and Karlstad University). During the last decade, more than 30 PhD students have graduated from the centre, which currently counts 28 active early career scientists (postdocs and PhD candidates). CNDS also supports early career researchers who advance in the field of interdisciplinary natural hazard and disaster science by awarding the CNDS Interdisciplinary Grants.

The centre contributes to the international educational curricula of disaster risk reduction through its renowned international research Summer School on Natural Hazards for doctoral students. Through the biennial conference Forum for Natural Hazards and Disasters and many national and international collaborations, CNDS keeps an open dialogue with practitioners in the field.

Please read more on our website about the centre and our upcoming events, e.g., the upcoming research seminar “Two years into the pandemic” on 22 of March, CNDS Summer School on Natural Hazards (22-26 August), and CNDS Forum for Natural Hazards and Disasters (20 October).

Climate Emergencies in Australian Local Governments: From Symbolic Act to Disrupting the Status Quo?


The paper examines the emerging phenomenon of climate emergency declarations. The case study is based on Victoria Australia and 30 other councils which have declared a climate emergency, particularly focusing on three of them. The drivers, meanings, and implications and to what extent the subsequent plans reflect a reframing of local government roles and actions are examined. The authors found thart the emergency declaration movement is catalysing councils beyond symbolic declarations potentially opening up space for change and disruption.

Floods, communal conflict and the role of local state institutions in Sub-Saharan Africa


Does the occurrence of flood disaster increase the risk of communal conflict and if so, does trust in state political institutions mitigate the adverse effect? 

Our CNDS Fellow, Kristina Petrova, has been looking into this issue and addressed the abovementioned questions by studying the intervening effect of trust in local governmental institutions at a sub-national level. She concludes that climate change is not a local phenomenon regardless of the need for national and local political structures in mitigating its effects. In addition, Kristina identifies the need for further research on the  interactive role between international governance, national regimes and local level leadership as a way to better understand the relationship between climate change and the risk of communal conflict.

Her research has been recently published under the title "Floods, communal conflict and the role of local state institutions in Sub-Saharan Africa" in Political Geography.

Pandemic responses at the subnational level: Exploring politics, administration, and politicization in Swedish municipalities


How did Swedish municipalities deal with the pandemic? The national response has been the highlight all over the world but little focus was given to the subnational level. 

Thus, CNDS fellow, Mikael Granberg, together with colleagues, dived into the politics, administration and politicization of the municipal response to the pandemic in Sweden. The article investigates the decision making processes and found, inter alia, that only a quarter of the municipalities activated the extraordinary crisis management committee while a majority of them had an alternate special organization in place. More interesting conclusions and results can be found in the article.

Exploring disaster impacts on adaptation actions in 549 cities worldwide


Whether disasters influence adaptation actions in cities is contested. Yet, the extant knowledge base primarily consists of single or small-N case studies, so there is no global overview of the evidence on disaster impacts and adaptation. 

In a recently published article, CNDS Fellows, Daniel NohrstedtJacob HilemanGiuliano Di BaldassarreCharles Parker (Uppsala university) and Maurizio Mazzoleni (VU Amsterdam) use regression analysis to explore the effects of disaster frequency and severity on four adaptation action types in 549 cities. Comparisons between cities across levels of adaptive capacity indicate a wealth effect. More affluent countries incur greater economic damages from disasters, but also have higher governance capacity, creating both incentives and opportunities for adaptation measures.

Multiform flood events must be appropriately defined to avoid misrepresentation of climate risk, to prioritize action in areas with disproportionate impact


One of the most recent articles published on the topic of flood risk in the contemporary world is released in the August edition of the Environmental Research Letters Journal (vol 17, no.8) under the title Multiform flood risk in a rapidly changing world: what we do not do, what we should and why it matters. Co-authored by well-known scientists in the fields of hydrology, climate and disaster science of whom one is CNDS Director, Giuliano Di Baldassarre and led by Andrew Kruczkiewicz, the article identifies challenges and potential consequences related to the oversimplification of disaster type representation in risk assessment and adaptation program design, focusing on non- or mis-assignment of flood type.

The publication provides the scientific, humanitarian, policy and financial communities with new insights in improving multiform flood risk assessment and policy development, such as disaggregation by flood subtype, the resilience of investors' balance sheets, implications for financial stability and climate risk disclosure, appropriate prioritization of resources for humanitarian action, and roles for the private sector, etc.

In order to address the trans-disciplinary knowledge gaps identified by the authors, they propose designing incentive structures for the financial sector to disclose disaster risk in a more disaggregated way,  improving modelling and characterization of multiform flood risks and leveraging satellite data to characterize this risk. They also state the importance of risk communication, and how new standards in messaging could save lives by clearly stating which types of disasters, such as flood types, are captured – and which are not.

“The COVID-19 pandemic reminded us that compound events can and will occur, further increasing demand for compound risk assessments, as well as for efforts to tailor them to specific sectors and spatiotemporal contexts.”

The article provides evidence-based trans-sectoral recommendations to enable joint efforts for more effective anticipatory action, risk reduction and resilience building and can be accessed on IOPScience:

6 million grant to EU project on water scarcity and climate change


CNDS Director, respectively fellow, Giuliano Di Baldassarre and Sina Kathami’s project TRANSCEND (Transformational and Robust AdaptatioN to water Scarcity and ClimatE chaNge under Deep uncertainty) has been selected for funding by the EU funding Horizon Climate.

This new EU project will be coordinated by the University of Salamanca (Spain). It involves 15 partner organizations from 13 different countries. It will receive EU funding for a total of 5.3 million EUR of which 602,000 EUR (above 6 million SEK) will go to the Department of Earth Sciences at Uppsala university.

Giuliano Di Baldassarre will be leading one of the work packages (WP3). Along with his research team at the Department, he will develop socio-hydrological models and methods for assessing water policies in several cases studies around the world.

Giuliano Di Baldassarre featured in a new article in National Geographic


CNDS Director, Giuliano Di Baldassarre has been featured in a new article in National Geographic which was aiming at addressing the question: "Is building more dams the way to save rivers?"

Earlier this year, World Wildlife Fund conducted a study on hydropower dams globally, thus understanding that almost two out of  three planned hydropower dams globally will be in river basins with very high or extreme risks for droughts, floods, or both, by the year 2050.

Already, hydropower generation has declined dramatically in many regions due to falling water levels in rivers. For some countries, such as Zambia, which gets most of its electricity from hydropower, losses in the amount of hydro-harnessed electricity can lead to major economic disruptions, which is what happened in the southern African country as a result of a decade-long drought that saw output decline by 40 percent.

Giuliano argues that “most scientists agree that these supply-demand cycles, or what we call rebound effects, might worsen the impact of drought and water shortage". 

The entire article can be accessed on National Geographic's home page.

Giuliano's paper on water shortages' effects can be accessed on Nature Sustainability's website.
