The modelling and management of flood risk in urban areas are increasingly recognized as global challenges. complexity these issues is a consequence the existence several distinct sources risk, including not only fluvial, tidal coastal flooding, but also exposure to runoff local drainage failure, various strategies that can be proposed. high degree vulnerability characterizes such expected increase future due effects climate change, growth population living cities, densification. An increasing awareness socio-economic losses environmental impact flooding clearly reflected recent expansion number studies related sometimes within framework adaptation change. goal current paper provide general review advances flood-risk management, while exploring perspectives fields research.

Key insights on needs in urban regional governance - Global urbanization (the increasing concentration settlements of the world population), is a driver and accelerator shifts diversity, new cross-scale interactions, decoupling from ecological processes, risk exposure to shocks. Responding challenges demands fresh commitments city–regional perspective ways that are explictly embedded Anthopocene bio- techno- noospheres, extend existing understanding city–nature nexus scale. Three key dimensions cities constrain or enable constructive, cross scale responses disturbances extreme events include 1) shifting 2) connectivity modularity, 3) complexity. These three characteristic current processes offer potential intervention points for local global action.

Human impacts outpace natural processes in the Amazon

Amazonian environments are being degraded by modern industrial and agricultural activities at a pace far above anything previously known, imperiling its vast biodiversity reserves globally important ecosystem services. The most substantial threats come from regional deforestation, because of export market demands, global climate change. Amazon is currently perched to transition rapidly largely forested nonforested landscape. These changes happening much too for species, peoples, ecosystems respond adaptively. Policies prevent the worst outcomes known must be enacted immediately. We now need political will leadership act on this information. To fail biosphere, we our peril.

Flood hazard potential reveals global floodplain settlement patterns

Nature Communications, Journal Year: 2023, Volume and Issue: 14(1)

Published: May 16, 2023

Flooding is one of the most common natural hazards, causing disastrous impacts worldwide. Stress-testing global human-Earth system to understand sensitivity floodplains and population exposure a range plausible conditions strategy identify where future changes flooding or might be critical. This study presents analysis inundated areas varying flood event magnitudes globally for 1.2 million river reaches. Here we show that topography drainage correlate with sensitivities as well societal behaviour. We find clear settlement patterns in which sensitive frequent, low magnitude events, reveal evenly distributed across hazard zones, suggesting people have adapted this risk. In contrast, extreme events tendency populations densely settled these rarely flooded being significant danger from potentially increasing given climate change.

A globally applicable framework for compound flood hazard modeling

Natural hazards and earth system sciences, Journal Year: 2023, Volume and Issue: 23(2), P. 823 - 846

Abstract. Coastal river deltas are susceptible to flooding from pluvial, fluvial, and coastal flood drivers. Compound floods, which result the co-occurrence of two or more these drivers, typically exacerbate impacts compared floods a single driver. While several global models have been developed, do not account for compound flooding. Local-scale provide state-of-the-art analyses but hard scale other regions as based on local datasets. Hence, there is need globally applicable hazard modeling. We develop, validate, apply framework modeling that accounts interactions between all It consists high-resolution 2D hydrodynamic Super-Fast INundation CoastS (SFINCS) model, automatically set up datasets coupled with routing model surge tide model. To test framework, we simulate historical events, Tropical Cyclone Idai Eloise in Sofala province Mozambique, compare simulated extents satellite-derived multiple days both events. Compared CaMa-Flood generally performs better terms critical success index (−0.01–0.09) hit rate (0.11–0.22) worse false-alarm ratio (0.04–0.14).

Cities, and in particular those coastal low-lying areas, are becoming increasingly susceptible to climate change, the impact of which is worsened by tendency for population concentration these areas. Therefore, comprehensive early warning systems necessary minimize harm from extreme events on communities. Ideally, such a system would allow all stakeholders acquire accurate up-to-date information respond effectively. This paper presents systematic review that highlights significance, potential, future directions 3D city modelling, systems, digital twins creation technology building resilience through effective management smart cities. In total, 68 papers were identified PRISMA approach. A total 37 case studies included, among (n = 10) define framework twin technology, 14) involve design virtual models, 13) entail generation alerts using real-time sensor data. concludes bidirectional flow data between model real physical environment an emerging concept enhancing resilience.
