Is the coastal future green, grey or hybrid? Diverse perspectives on coastal flood risk management and adaptation in the UK

Cambridge Prisms Coastal Futures, Год журнала: 2024, Номер 2

Опубликована: Янв. 1, 2024

Abstract Climate change-induced sea level rise has exacerbated coastal change putting millions of people at risk from hazards, such as flooding and erosion. Nature-based solutions have been recognised an opportunity to simultaneously address the hazard risks achieve biodiversity goals. While are included in climate adaptation strategies, “hard” engineered still often preferred by those implementing schemes. We sought explore diverse perspectives on UK flood management among interested and/or affected groups utilising Q-methodology. identified five perspectives: (1) The Pro-Green Practitioners; (2) Future-Planning Relocators; (3) Case-by-Case Thinkers; (4) Cautious Practitioners (5) Change Concerned. All strongly valued co-benefits nature-based their role reduction. None prioritised hard-engineered primary protection strategy UK, though they protecting essential infrastructure. main disagreements between were need for relocation whether could cause social inequalities. Q-methodology does not identify how prevalent are, thus further research is needed assess acceptance solutions.

Statistically downscaled CMIP6 ocean variables for European waters

Climate change impact studies need climate projections for different scenarios and at scales relevant to planning management, preferably a variety of models realizations capture the uncertainty in these models. To address current gaps, we statistically downscaled (SD) 3-7 CMIP6 five key indicators marine habitat conditions: temperature, salinity, pH, oxygen, chlorophyll across European waters three SSP1-2.6, SSP2-4.5, SSP5-8.5. Results provide ensemble averages estimates that can serve as input data projecting potential success range Nature-based Solutions, including restoration habitat-forming species such seagrass Mediterranean kelp coastal areas Portugal Norway. Evaluation with observations from four regions (North Sea, Baltic Bay Biscay, Sea) indicates SD realistically climatological conditions historical period 1993-2020.

Nature-based solutions and restoration are intertwined but not identical: Highlighting implications for societies and ecosystems

Nature-Based Solutions (NbS) and ecosystem restoration are often conflated, but cannot be assumed to identical. Understanding choosing between different framings is important. It affects our ambitions for reinvigorating natural systems, the range of actors resources that can drawn on achieve them, every part how interventions planned, delivered appraised. To explore differences relationships concepts we focus freshwater catchment management initiatives, points relevant initiatives focused other settings or framed in terms. We firstly identify potential by analysing accepted definitions Solutions; then illustrate these with examples UK Ireland, which familiar from own work collaborations. These real-world cases demonstrate NbS lead priorities ecosystems processes managed; who involved projects develop. The also show may somewhere a continuum two concepts, potentially shift over time.

Pluvial flood is a natural hazard occurring from extreme rainfall events that affect millions of people around the world, causing damages to their properties and lives. The magnitude projected climate risks indicates urgency putting in place actions increase resilience. Through this study, we develop Machine Learning (ML) model predict pluvial risk under Representative Concentration Pathways (RCP) 4.5 8.5 for future scenarios precipitation period 2021-2050, considering different triggering factors patterns. analysis focused on case study area Metropolitan City Venice (MCV) considers 212 historical occurred timeframe 1995-2020. methodology developed implements spatio-temporal constraints ML improve prediction change. Accordingly, cross-validation approach was applied frame able at any time space. This complemented with data selection nine representative territorial features contribute events. Logistic Regression most reliable model, highest AUC score, providing robust result both validation test set. Maximum cumulative 14 days important feature contributing occurrence. final output represented by suite maps flood-prone areas MCV each quarter year 1995-2020 based data, 2021-2050 RCP4.5 scenarios. Overall, results underline consistent (i.e., very high extremely flooding) more catastrophic scenario RCP8.5 decades compared baseline.

Stakeholders’ support is essential for the effective and successful implementation of policies that prioritize enhancing preserving ocean coastal ecosystems. However, cross-national studies examining factors influencing stakeholders’ policy are still lacking. The current study aimed to provide preliminary evidence on (e.g., socio-demographic factors, country income levels, perceived impacts marine ecosystems) affect endorsement a centered To conduct study, we applied Bayesian Mindsponge Framework (BMF) dataset 709 stakeholders from 42 countries generated by MaCoBioS—a research project funded European Commission Horizon 2020. BMF allowed us adopt distinctive innovative approach analyzing data drawing valuable development insights. results show no differences in levels across with different ages, education, levels. female tended prioritizing protection more than their male counterparts. Stakeholders perceiving ecosystem preservation human wellbeing, climate weather, change reduction also strongly. Meanwhile, ecosystems global local economies had an ambiguous effect support. Based these findings, suggest raising awareness knowledge can help improve policies. Moreover, it necessary concentrate communicating adverse consequences induced ecosystems’ loss health) less economic aspects. underscores significance environmental education awareness-raising campaigns disseminating information cultivating eco-surplus culture. This culture inspires actively participate conservation efforts, going beyond mere sustainability aiming create positive impacts.

Опубликована: Сен. 23, 2024

Abstract Many seafood products marketed as “sustainable” are not. More exacting sustainability standards needed to respond a fast-changing world and support United Nations SDGs. Future fisheries must operate on principles that minimise impacts marine life, adapt climate change allow regeneration of depleted biodiversity, while supporting enhancing the health, wellbeing resilience people communities. We set out 11 actions achieve these goals.
