Floating solar photovoltaics in water bodies is a novel clean energy technology which has been developed rapidly during the last decade. The current work investigates possibility and potential of installing floating photovoltaic systems existing hydropower plants Greece. Studies related with use reservoirs Greece are limited so far. characteristics 24 have used for estimation can be installed their reservoirs. It found that nominal power these reservoirs, covering 10% surface, at 3,861 MWp while annual generated electricity 5,212.35 GWh corresponding 10.04 % demand country. capacity factor integrated hydro increased by more than 20%. research indicates host, dams, generating significant amounts green they also result many environmental benefits. These contribute, together other benign technologies, achievement national EU target net zero carbon emissions 2050.

The Mediterranean Basin is affected by climate changes that may have negative effects on forests. This study aimed to evaluate the ability of 17 forests located in Island Sardinia resist or adapt past and future climate. experiencing a decreasing anthropic pressure forests, but drought-triggered dieback trees was recently observed confirmed analysis 20 years satellite tree-cover data (MOD44B). Significant trends yearly tree cover broad-leaved vegetation, while significative positive were found bushy sclerophyllous vegetation. Vegetation behavior resulted being related mean annual precipitation (MAP); for MAP < 700 mm, we decline tall stands an increase short ones, opposite vegetations. In with > both are stable, regardless growing vapor-pressure deficit (VPD) temperature. No correlation between drivers found, positively MAP1990–2019 negatively VPD. We modeled those relationships, then used them coarsely predict twelve scenarios (derived from HADGEM2-AO (CMIP5) HadGEM3-GC31-LL (CMIP6) models) forest covers. All show VPD increase, higher its trees-cover loss. contrasting. SC6, line trends, predicts further drop (−7.6%), which would correspond average 2.1-times-greater reduction (−16.09%).

Wildfires are an escalating global threat, jeopardizing ecosystems and human activities. Among the repercussions in ecosystem services of burnt areas, there altered hydrological processes, which increase risks flash floods. There is limited research addressing this issue a comprehensive way, considering pre- post-fire conditions to accurately represent flood events. To address gap, we present novel approach combining multiple methods tools for accurate representation The 2019 Kineta, Central Greece used as study example our framework. We simulated meteorological that caused using atmospheric model WRF-ARW. burn extent severity were assessed through remote sensing techniques. 2D HEC-RAS hydraulic–hydrodynamic was then applied event, rain-on-grid technique. findings underscore influence wildfires on flooding dynamics, highlighting need proactive measures increasing risks. integrated multidisciplinary offers improved understanding responses, also establishes robust framework, transferable other similar cases, contributing thus enhanced protection actions face fire-related disasters.

Agro-climatic indicators (AgcIs) provide a suitable tool to evaluate the implications of climate change on agriculture by simplifying plant–climate interactions. However, developing reliable AgcIs requires high-quality historical datasets. Consequently, reanalysis products (RPs) are frequently used as potential reference dataset for observed in agricultural studies. This study aims compare five RPs (ERA5, ERA5-Land, SCOPE Climate, FYRE and RFHR) at reproducing over France. The evaluated against SYNOP meteorological data 1996–2012 period, focusing six specific apple, maize, vine crops. findings show that perform well temperature-based AgcIs, with some slight discrepancies areas complex topography. all tend overestimate precipitation amounts underestimate dry days, leading poor performance precipitation-based AgcIs. emphasizes need thorough evaluation both especially if intended support operational decision-making.
