Key observational indicators of climate change in the Arctic, most spanning a 47 year period (1971–2017) demonstrate fundamental changes among nine key elements Arctic system. We find that, coherent with increasing air temperature, there is an intensification hydrological cycle, evident from increases humidity, precipitation, river discharge, glacier equilibrium line altitude and land ice wastage. Downward trends continue sea thickness (and extent) spring snow cover extent duration, while...
Abstract. The Arctic is a water-rich region, with freshwater systems covering about 16 % of the northern permafrost landscape. Permafrost thaw creates new ecosystems, while at same time modifying existing lakes, streams, and rivers that are impacted by thaw. Here, we describe current state knowledge regarding how affects lentic (still) lotic (moving) systems, exploring effects both thermokarst (thawing collapse ice-rich permafrost) deepening active layer (the surface soil thaws refreezes...
Abstract Terrestrial hydrology is central to the Arctic system and its freshwater circulation. Water transport water constituents vary, however, across a very diverse geography. In this paper, which component of Freshwater Synthesis, we review processes in terrestrial drainage how they function change seven hydrophysiographical regions (Arctic tundra, boreal plains, shield, mountains, grasslands, glaciers/ice caps, wetlands). We also highlight links between other components system. terms key...
Abstract The Sustainable Development Goals (SDGs) of the United Nations Agenda 2030 represent an ambitious blueprint to reduce inequalities globally and achieve a sustainable future for all mankind. Meeting SDGs water requires integrated approach managing allocating resources, by involving actors stakeholders, considering how resources link different sectors society. To date, management practice is dominated technocratic, scenario‐based approaches that may work well in short term but can...
Wetlands are often considered as nature-based solutions that can provide a multitude of services great social, economic and environmental value to humankind. Changes in land-use, water-use climate all impact wetland functions services. These changes occur at scales extending well beyond the local scale an individual wetland. However, practical applications, engineering management decisions usually focus on projects site conditions. Here, we systematically investigate if what extent research...
Risk management has reduced vulnerability to floods and droughts globally1,2, yet their impacts are still increasing3. An improved understanding of the causes changing is therefore needed, but been hampered by a lack empirical data4,5. On basis global dataset 45 pairs events that occurred within same area, we show risk generally reduces faces difficulties in reducing unprecedented magnitude not previously experienced. If second event was much more hazardous than first, its impact almost...
Abstract As flood impacts are increasing in large parts of the world, understanding primary drivers changes risk is essential for effective adaptation. To gain more knowledge on basis empirical case studies, we analyze eight paired floods, that is, consecutive events occurred same region, with second causing significantly lower damage. These success stories reduction were selected across different socioeconomic and hydro‐climatic contexts. The potential societies to adapt uncovered by...
Abstract Numerous international scientific assessments and related articles have, during the last decade, described observed potential impacts of climate change as well other environmental stressors on Arctic ecosystems. There is increasing recognition that projected changes in freshwater sources, fluxes, storage will have profound implications for physical, biogeochemical, biological, ecological processes properties terrestrial However, a significant level uncertainty remains relation to...
Most research on hydrological risks focuses either flood risk or drought risk, whilst floods and droughts are two extremes of the same cycle. To better design disaster reduction (DRR) measures strategies, it is important to consider interactions between these closely linked phenomena. We show examples of: (a) how DRR can have (unintended) positive negative impacts opposite hazard; (b) be negatively impacted by hazard. focus dikes levees, dams, stormwater control upstream measures, subsurface...
Abstract Economic inequality is rising within many countries globally, and this can significantly influence the social vulnerability to natural hazards. We analysed income flood disasters in 67 middle- high-income between 1990 2018 found that unequal tend suffer more fatalities. This study integrates geocoded mortality records from 573 major with population economic data perform generalized linear mixed regression modelling. Our results show significant association persists after accounting...
Climate change is expected to alter hydrological and biogeochemical processes in high-latitude inland waters. A critical question for understanding contemporary future responses environmental how the spatio-temporal dynamics of runoff generation will be affected. We sampled stable water isotopes soils, lakes rivers on an unprecedented scale along a 1700 km transect over three years Western Siberia Lowlands. Our findings suggest that snowmelt mixes with, displaces, large volumes stored...
Abstract. One common approach to cope with floods is the implementation of structural flood protection measures, such as levees or flood-control reservoirs, which substantially reduce probability flooding at time implementation. Numerous scholars have problematized this approach. They shown that increasing levels can attract more settlements and high-value assets in areas protected by new measures. Other studies explored how measures generate a sense complacency, act preparedness. These...
To understand the spatiotemporal changes of flood risk, we need to determine way in which humans adapt and respond events. One adaptation option consists resettling away from flood-prone areas prevent or reduce future losses. We use satellite nighttime light data discern relationship between long-term human proximity rivers occurrence catastrophic Moreover, explore how these relationships are influenced by different levels structural protection. found that societies with low protection tend...

Abstract Climate change, globalization, urbanization, social isolation, and increased interconnectedness between physical, human, technological systems pose major challenges to disaster risk reduction (DRR). Subsequently, economic losses caused by natural hazards are increasing in many regions of the world, despite scientific progress, persistent policy action, international cooperation. We argue that these dramatic figures call for novel approaches new types data collection integrate two...
Arctic warming alters regional hydrological systems, as permafrost thaw increases active layer thickness and in turn the pathways of water flow through landscape. Further, may change connectivity between deeper shallower groundwater surface altering terrestrial balance distribution. Thermokarst lakes wetlands offer a window into such changes these landscape elements depend on are some most dynamic widespread features lowland regions. In this study we used Landsat remotely sensed imagery to...
Abstract This study presents a global explanatory analysis of the interplay between severity flood losses and human presence in floodplain areas. In particular, we relate economic fatalities caused by floods during 1990–2000, with changes population built‐up areas floodplains 2000–2015 exploiting archives. We found that increased period for majority analyzed countries, albeit frequent previous 1990–2000. some however, decreased 2000–2015, following more severe occurred 1975–2000. Our shows...
Hydrogeological hazards are increasingly causing damage worldwide due to climatic and socio-economic changes. Building resilient communities is crucial reduce potential losses. To this end, one of the first steps understand how people perceive threats around them. This study aims at exploring risk awareness of, preparedness to, face hydrological changes over time. A cohort was carried out in two villages northeastern Italian Alps, Romagnano Vermiglio, affected by debris flows 2000 2002....
Abstract. As the adverse impacts of hydrological extremes increase in many regions world, a better understanding drivers changes risk and is essential for effective flood drought management climate adaptation. However, there currently lack comprehensive, empirical data about processes, interactions, feedbacks complex human–water systems leading to impacts. Here we present benchmark dataset containing socio-hydrological paired events, i.e. two floods or droughts that occurred same area. The...
Abstract. Droughts are often long-lasting phenomena, without a distinct start or end and with impacts cascading across sectors systems, creating long-term legacies. Nevertheless, our current perceptions management of droughts their event-based, which can limit the effective assessment drought risks reduction impacts. Here, we advocate for changing this perspective viewing as hydrological–ecological–social continuum. We take systems theory focus on how “memory” causes feedback interactions...
