... Typically, irrigation plans are created using mathematical models. While irrigation systems can be created with the help of technology in many developed countries, such models often have significant problems in implementation in most developing countries, often due to incomplete data [98,99]. ...

... Technological advances in IASs continue to increase rapidly [3][4][5][6][7][8][9]. Along with it, the behavioral and socio-economic determinants of farmers for the adoption of these efficient irrigation technologies are also evolving. ...

... The domain of flood cyberinfrastructures has seen transformative advancements in recent years (Curtis and Fowler, 2012;Andreasen et al., 2016;Escudier et al., 2016;Jones et al., 2017;Borsch et al., 2018;De Filippis et al., 2022). This growth is underscored by the development of multi-hazard and multi-criteria platforms (Ries et al., 2010;Heil et al., 2014;Kochilakis et al., 2016;Ong et al., 2017;Abily et al., 2020;Lin et al., 2020;Mamassis et al., 2021). Concurrently, digital watershed designs have emerged (Qiu et al., 2022), complemented by reservoir inundation mapping tools (Aekakkararungroj et al., 2020) and specialized Python utilities (Christensen et al., 2017). ...

... Seeking solutions with the aim to achieve healthier products through eco-friendly production systems, organic cultivation practices can be considered as a solution since inorganic N and synthetic agrochemicals are avoided. According to Gatsios et al. [10][11][12][13], N supply in organic agriculture mainly relies on green and animal manures, composts, crop rotation with legumes, and utilisation of intercropping approaches. The introduction of the above-mentioned renewable N sources into agricultural production systems can also reduce contamination of water resources with nitrates [14] and increase the diversity of soil microbiota [15], thereby fostering soil nutrient availability, productivity, and health [16]. ...

... Similarly, more frequent and severe flood events can affect the recovery phase of microbenthic assemblages from eutrophication, which in turn impacts bivalves for fishers who rely on estuarine resources (Cardoso et al., 2008). Climate change can also directly impact food production, reducing food production in regions like southern Europe (Harrison et al., 2015), such as by increasing water demand in ways that make the rainfed cultivation of olive crops no longer economically feasible (Fotia et al., 2021). ...

... The leaching factor (α) was set at 10% (or 0.1) (Hoekstra et al., 2011), cmax was set at 50 mg NO3 L -1 (or 11.29 mg N L -1 ) according to the EU Nitrates Directive, 91/676/EEC and cnat was assumed to be zero (Hoekstra et al., 2011). For the estimation of crop evapotranspiration (ETc) the ETo timeseries which was provided by the virtual agrometerological station, that IRMAS_SYS creates for each specific field were used (Malamos et al., 2017). ...

... Although the Brooklyn Grange retained little stormwater during the growing seasons, it should be noted that precipitation exceeded ET at the Brooklyn Grange, which means that stormwater discharge and irrigation demands could be eliminated while maintaining satisfactory yield through enhanced water-holding capacity of the substrate and recirculating drainage (Harada et al., 2018b). Outdoor hydroponic systems can also be used for rooftop farming, which could eliminate drainage discharge by using closed-circuit systems for nutrient solution, and incorporating stormwater recycle systems (Orsini et al., 2014;Sanyé-Mengual et al., 2015b;Rodríguez-Delfín et al., 2017;Tsirogiannis et al., 2017). However, water management using electric pumps requires further research because pumps' electricity consumption can be the largest environmental cost of rooftop farming (Sanyé-Mengual et al., 2015b). ...

... The main objective of our experiments is to measure performance in terms of quality of the generated models and the execution time of four different algorithms for interpolation of the reference evapotranspiration: Inverse Distance Weighting, Kriging, Random Forest and a Random Forest variation for spatial predictions. The first two represent the techniques conventionally used for spatial interpolation of environmental variables (Li and Heap, 2014), so the choice of IDW and Kriging is due to the fact that they are frequently used for interpolation of evapotranspiration (Xavier et al., 2016;Hodam et al., 2017;Malamos et al., 2017) and other environmental variables (Gerstmann et al., 2016;Shtiliyanova et al., 2017), producing small interpolation error. ...

... More contemporary versions of berceaux, also known as pergolas or arbour walkways, are nowadays constructed in Dutch private gardens and public parks, but are not yet commonly used for microclimate amelioration in urban public spaces. Despite this, research shows that pergolas can significantly reduce radiant temperature by casting shade (Hoyano, 1988;Katsoulas et al., 2017;Watanabe, Nagano, Ishii, & Horikoshi, 2014). Some studies also found a reduction in air temperature below pergolas (Ch afer, Pisello, Piselli, & Cabeza, 2020; Katsoulas et al., 2017). ...

... In the framework of the IRMA project which was funded by the European Territorial Cooperation Programme (ETCP) GREECE-ITALY 2007-2013, the National Observatory of Athens (NOA) delivered forecast data to the University of Ioannina for almost four years [18], to be integrated into a platform for estimating near-real-time crop water requirements and irrigation forecasts across the study area [19]. The forecasts were available early each day, for the current (Day 0) and six days ahead (Day 1 to Day 6), in the form of a text file that contained all the information from Grid 2 of BOLAM model [20,21]. ...
