In highly acidic or highly alkaline media, FL photodegradability is greatly retarded. Scavenging experiment infers considerable contribution of holes over electrons in photodegradation reaction. The biosynthesized ZnO shows high durability in FL photodegradation after four reusing cycles. These promising findings highlight new insights for biogenic synthesis of tuned size/controlled morphology semiconductor NPs relevant to environmental remediation applications.Present study has attempted to measure Water Richness (WR) and Wetland Habitat Suitability (WHS) in deltaic environment and assessed their spatial linkages. Water richness exhibits availability of water in wetland and its dynamicity, whereas wetland habitat suitability depicts physical habitat ambiance of a wetland toward vibrant ecosystem. Both the components are very essential and should be measured to explore ecosystem service and environmental heath of a region. For investigating water richness of the wetland six water availability indicating parameters have been chosen and for assessing wetland habitat suitability four additional parameters have been taken into consideration. Four widely used and recognised machine learning algorithms like Reduced Error Pruning (REP) tree, Random forest, Artificial Neural Network (ANN) and Support Vector Machine (SVM) have been employed here in order to develop suitable model at two phases. Results reveal that very high water rich zone is found over 200-215 km2 wetland area followed by high water rich zone over 125-140 km2 wetland area in both the phases. Wetland habitat suitability assessment shows only 100-150 km2 of the wetland having very high suitability and 110-120 km2 of wetland having high suitability. Elenestinib in vitro Field investigation and accuracy assessment support the validity and acceptability of the results. Spatial linkage between water richness and habitat suitability demonstrates that 30-40% very high water rich zone represents very high habitat suitability figuring out importance of both the models. Therefore, results recommend that only water richness of the wetlands of the wetlands is not enough to represent the habitat suitability in the densely populated riparian flood plain region.Land reclamation is critically required to overcome the environmental and anthropogenic challenges in arid lands. The Western Nile Delta region, Egypt, is experiencing rapid reclamation processes for agriculture expansion. West Nubaria (781.92 km2) is one of the newly reclaimed areas in the Western Nile Delta. Due to extensive agricultural practices and poor management, an artificial saline lake formed in this area. Two primary goals of this research; 1) monitoring the annual change in the lake surface area between 2013 and 2017. 2) Predicting the areal extent of the lake surface in 2020, 2030, and 2040 based on two management scenarios. The maximum likelihood classifier (MLC) was applied to distinguish the LULC classes in 2017. Additionally, the annual modified normalized difference water index (MNDWI) calculated between 2013 and 2017. Then, the land change modeler (LCM) was utilized to predict the 2017 free water area based on the resulted MNDWI maps of 2013 and 2016 using two scenarios. With the high agreement between the actual and predicting free water area of 2017 (Kappa index = 0.93), the LCM was applied to predict the future surface water expansion in 2020, 2030, and 2040. Three land use/land cover (LULC) distinguished in 2017; agricultural land, uncultivated land, and free water class based on MLC. The MNDWI results reveal that there was an increase in the surface water area from 593 to 883 ha between 2013 and 2017, respectively. The LCM results indicate that expected increases in the surface water areas of 1068, 1711, and 2267 ha in 2020, 2030 and 2040, respectively (scenario 1) and 1065, 1726, and 2343 ha in the respective dates (scenario 2). These extend will exist over the agricultural and uncultivated lands surrounding the lake causing land degradation. Two solutions were suggested to combat the waterlogging and land degradation in this area by evacuating the artificial saline lake.Climate change not only intensifies eutrophication and enhances the rainfall, but also elevates the contents of greenhouse gases, which can further increase the intensity and frequency of extreme precipitation events. The effectivity of phytoremediation of urban wastewaters by water hyacinths under an extreme rainfall event (up to 380 mm d-1) was investigated using self-designed fabrications with six flow rates (2-15 m3 d-1) in situ on pilot scale for 30 days. The results suggest that water hyacinths had high N and P removal capacities even under adverse conditions such as low dissolved oxygen concentrations (DO, 7 mg L-1). Specifically, the highest removal yields of N and P were 13.14 ± 0.47 g N·m-2·d-1 and 2.12 ± 0.04 g P·m-2·d-1, respectively. The results indicate that water hyacinths can be used for water treatment to reduce the amounts of NH4+-N, dissolved organic nitrogen (DON) and phosphate (PO43-) even during extreme precipitation events. Moreover, DO increased due to wet deposition, runoff and surface flows during the extreme rainfall event, resulting in shifts between nitrification and denitrification processes which significantly altered nitrogen forms in urban wastewater. Results of this study suggest that water hyacinths could be recommended as a cost-effective and eco-friendly technology for urban wastewater phytoremediation in areas suffering from frequent extreme precipitation events.Considering the existing world population, set of environmental impacts, and predicted changes in dietary trends, one can expect that, in the coming decades, food security will remain high on the list of sustainability concerns. In relation to this challenge, Europe's Common Agricultural Policy (CAP) must address a diverse set of goals (i) guarantee a stable and affordable food supply; (ii) preserve the socioeconomic stability of farmers by guaranteeing their economic viability; (iii) protect the environment by reducing pressures on agroecosystems; and (iv) improve food security by reducing import dependence. Policies related to these diverse goals are likely to generate adverse side-effects. A particularly uncomfortable concern is Europe's massive reliance on imported feed commodities. The European Union (EU) is unlikely to be capable of domestically producing currently imported agricultural commodities and a significant move to internalize imports would dramatically increase pressures on local ecosystems. Faced with that potential predicament, it is essential to have a robust information system capable of simultaneously addressing a variety of policy concerns.
