This study evaluated the effectiveness of NASA Earth Exchange Global Daily Downscaled models from CMIP6 experiments (hereafter; NEX-GDDP-CMIP6) in reproducing observed precipitation and temperature across East Africa (EA) 1981 to 2014. Additionally, climate changes were estimated under various emission scenarios, namely low (SSP1-2.6), medium (SSP2-4.5), high (SSP5-8.5) scenarios. Multiple robust statistics metrics, Taylor diagram, interannual variability skill (IVS) employed identify best-performing models. Significant trends future are using Mann-Kendall Sen’s slope estimator tests. The results highlighted IPSL-CM6A-LR, EC-Earth3, CanESM5, INM-CM4-8 as for annual March May (MAM) respectively. By end this century, MAM projected increase by 40% 4.5 °C, respectively, SSP5-8.5. Conversely, a decrease 5% 0.8 °C was SSP2-4.5 SSP1-2.6, Long-term mean increased all scenarios (SSP1-2.6, SSP2-4.5, SSP5-8.5), with near-term showing Rwanda, Burundi, Uganda, some parts Tanzania. Under SSP5-8.5 scenario, rise exceeded 2–6 most regions area, fastest warming trend over 6 diverse areas. Thus, greenhouse gas (GHG) can be very harmful EA further GHG control is needed.

This article provides a stocktake of the adaptation literature between 2013 and 2019 to better understand how responses affect risk under particularly challenging conditions compound climate events. Across 39 countries, 45 response types hazards display anticipatory (9%), reactive (33%), maladaptive (41%) characteristics, as well hard (18%) soft (68%) limits adaptation. Low income, food insecurity, access institutional resources finance are most prominent 23 vulnerabilities observed negatively responses.

The latest evidence suggests that multi-hazards and their interrelationships (e.g., triggering, compound, consecutive hazards) are becoming more frequent across Europe, underlying a need for resilience building by moving from single-hazard-focused to multi-hazard risk assessment management. Although significant advancements were made in our understanding of these events, mainstream practice is still focused on risks due single hazards flooding, earthquakes, droughts), with limited the stakeholder needs ground. To overcome this limitation, paper sets out understand challenges towards management through perspective European stakeholders. Based five workshops different pilots (Danube Region, Veneto Scandinavia, North Sea, Canary Islands) an expert workshop, we identify prime challenges: i) governance, ii) knowledge multi-risks, iii) existing approaches disaster management, iv) translation science policy practice, v) lack data. These inherently linked cannot be tackled isolation path dependency posing hurdle transitioning single- Going forward, promising overcoming some challenges, including emerging characterisation, common terminology, comprehensive framework guiding We argue think beyond natural include other threats creating overview risks, as well promoting thinking reduction context larger development goals.

Abstract Hydrological extremes, such as droughts and floods, can trigger a complex web of compound cascading impacts (CCI) due to interdependencies between coupled natural social systems. However, current decision‐making processes typically only consider one impact disaster event at time, ignoring causal chains, feedback loops, conditional dependencies impacts. Analyses capturing these patterns across space time are thus needed inform effective adaptation planning. This perspective paper aims bridge this critical gap by presenting methods for assessing the dynamics multi‐sector CCI hydrological extremes. We discuss existing challenges, good practices, potential ways forward. Rather than pursuing single methodological approach, we advocate pluralism. see complementary or even convergent roles analyses based on quantitative (e.g., data‐mining, systems modeling) qualitative mental models, storylines). The data‐driven knowledge‐driven provided here serve useful starting point understanding both high‐frequency low‐likelihood but high‐impact CCI. With perspective, hope foster research improve development strategies reducing risk

Abstract In the last few years, world has experienced numerous extreme droughts with adverse direct, cascading, and systemic impacts. Despite more frequent severe events, drought risk assessment is still incipient compared to that of other meteorological climate hazards. This mainly due complexity drought, high level uncertainties in its analysis, lack community agreement on a common framework tackle problem. Here, we outline effectively assess manage risks, perspective needed. We propose novel highlights nature show operationalization using example 2022 Europe. research emphasizes solutions growing risks should not only consider underlying drivers for different sectors, systems or regions, but also be based an understanding sector/system interdependencies, feedbacks, dynamics, compounding concurring hazards, as well possible tipping points globally and/or regionally networked risks.

Alpinia officinarum , commonly known as Galangal, is not only widely used a medicinal plant but also holds significant ornamental value in horticulture and landscape design due to its unique structure floral aesthetics China. This study evaluates the impact of current future climate change scenarios (ssp126, ssp245, ssp370, ssp585) on suitable habitats for A. A total 73 reliable distribution points were collected, 11 key environmental variables selected. The ENMeval package was optimize Maxent model, potential areas predicted combination with Biomod2. results show that optimized model accurately Under low emission (ssp126 ssp245), habitat area increased expanded towards higher latitudes. However, under high (ssp370 ssp585), significantly decreased, species range shrinking by approximately 3.7% 19.8%, respectively. Through Multivariate similarity surface (MESS) most dissimilar variable (MoD) analyses revealed variability scenarios, especially ssp585, led large-scale contraction rising temperatures unstable precipitation patterns. Changes center suitability location showed ’s located Guangxi, gradually shifts northwest, while this shift becomes more pronounced. These findings provide scientific basis conservation germplasm resources management strategies response change.
