Australia Electric Vehicles Charging Infrastructure
Electric vehicle (EV) adoption is growing worldwide with increasing market pull from consumers and market push from manufacturers of vehicles and charging equipment, as well as others in the supply chain. Governments have begun developing policies to support EV uptake and local governments, in particular, are examining what role they should play. In Australia, a large country with low population density, EV uptake has been slower in comparison to other similar economies.

Microbiome and Root Traits in Organic Phosphorus Mobilization
Moving toward more sustainable sources for managing phosphorus (P) nutrition in agroecosystems, organic phosphorus (Po) derived from organic inputs and soil is increasingly considered to complement mineral P fertilizer. However, the dynamics of P added by organic input in soil-plant systems is still poorly understood and there is currently no clear information on how the Po composition of these amendments determines P availability through interactions with the soil microbiome and root traits. Here, we review the main mechanisms of rhizosphere microbiome and root traits governing the dynamics of organic input/soil-derived Po pools in the soil-plant system.

Cyanobacteria Controlling Agricultural Plant Diseases
Cyanobacteria, also called blue-green algae, are a group of prokaryotic microorganisms largely distributed in both terrestrial and aquatic environments. They produce a wide range of bioactive compounds that are mostly used in cosmetics, animal feed and human food, nutraceutical and pharmaceutical industries, and the production of biofuels. Nowadays, the research concerning the use of cyanobacteria in agriculture has pointed out their potential as biofertilizers and as a source of bioactive compounds, such as phycobiliproteins, for plant pathogen control and as inducers of plant systemic resistance. The use of alternative products in place of synthetic ones for plant disease control is also encouraged by European Directive 2009/128/EC.

Applications of Light Wavelength Conversion Materials in Agriculture
As new fluorescent materials, light wavelength conversion materials (light conversion agents) have attracted increasing attention from scientific researchers and agricultural materials companies due to their potential advantages in efficiently utilizing solar energy and increasing crop yield. According to the material properties, the light conversion agents can be divided into fluorescent dyes, organic rare-earth complexes, and inorganic rare-earth complexes. The current researches indicates that the fluorescent dyes have relatively high production costs, poor light stability, difficult degradation processes, and easily cause pollution to the ecological environment. The organic rare-earth complexes have short luminescence times, high production costs, and suffer from rapid decreases in luminescence intensity. Compared with fluorescent dyes and organic rare-earth complexes, although rare-earth inorganic complexes have high luminous efficiency, stable chemical properties, and better spectral matching performance, the existing inorganic light conversion agents have relatively poor dispersibility in agricultural films.

Non-Ferrous Metal Ions Removal by PIMs Doped 2-Alkylimidazoles
Polymer inclusion membranes (PIMs) are an attractive approach to the separation of metals from an aqueous solution. This study is concerned with the use of 2-alkylimidazoles (alkyl = methyl, ethyl, propyl, butyl) as ion carriers in PIMs. It investigates the separation of copper (II), zinc (II), cobalt (II), and nickel (II) from aqueous solutions with the use of polymer inclusion membranes. PIMs are formed by casting a solution containing a carrier (extractant), a plasticizer (o-NPPE), and a base polymer such as cellulose triacetate (CTA) to form a thin, flexible, and stable film.

Remediating Endocrine-Disrupting Compounds
Over the years, the persistent occurrence of superfluous endocrine-disrupting compounds (EDCs) (sub µg L−1) in water has led to serious health disorders in human and aquatic lives, as well as undermined the water quality. At present, there are no generally accepted regulatory discharge limits for the EDCs to avert their possible negative impacts. Moreover, the conventional treatment processes have reportedly failed to remove the persistent EDC pollutants, and this has led researchers to develop alternative treatment methods. Comprehensive information on the recent advances in the existing novel treatment processes and their peculiar limitations is still lacking. In this regard, the various treatment methods for the removal of EDCs are critically studied and reported in this entry.

Ecosystem Service Trade-Offs/Synergies of Karst Desertification Control
Ecosystem services, as the term of a scientific period, began in 1970 with the publication of the UN University’s report on “Human Impact on the Global Environment”. Since then, Costanza has proposed that ecosystem services are benefits derived directly or indirectly by human beings from the ecosystem, which are used to maintain the natural environmental conditions and utilities on which human beings depend for survival and development. Trade-offs, as a fundamental concept, first appeared in economics and were defined as opportunity costs. Where resources are scarce, an individual or group must give up a certain amount of additional scarce resources to obtain more of the scarce resources. Karst desertification refers to the land degradation phenomenon caused by the disturbance and destruction of unreasonable human social and economic activities under the fragile karst environment in the subtropical zone, which is manifested by soil erosion, gradual rock exposure, land productivity degradation, and a desert-like landscape on the surface. The results of management over the years show that forests, as the main provider of ecosystem services, have the functions of water conservation, soil and water conservation, carbon sequestration, and climate change mitigation. In particular, they play an irreplaceable role in managing karst desertification.

Microplastics Contamination of the Yenisei River
This study is a pioneering attempt to count microplastics (MPs) in the Yenisei River system to clarify the role of Siberian Rivers in the transport of MPs to the Arctic Ocean. The average MPs content in the surface water of the Yenisei large tributary, the Nizhnyaya Tunguska River, varied from 1.20 ± 0.70 to 4.53 ± 2.04 items/m3, tending to increase along the watercourse (p < 0.05). Concentrations of MPs in bottom sediments of the two rivers were 235 ± 83.0 to 543 ± 94.1 with no tendency of downstream increasing. Linear association (r = 0.952) between average organic matter content and average counts of MPs in bottom sediments occurred. Presumably MPs originated from the daily activities of the in-situ population. Further spatial-temporal studies are needed to estimate the riverine MPs fluxes into the Eurasian Arctic seas.

Kouvola
Kouvola (Finnish pronunciation: [ˈkou̯ʋolɑ]) is a city and municipality in southeastern Finland. It is located along the Kymijoki River in the region of Kymenlaakso, 62 kilometres (39 mi) kilometers east of Lahti, 87 kilometres (54 mi) west of Lappeenranta and 134 kilometres (83 mi) northeast of the capital, Helsinki. With Kotka, Kouvola is one of the capital centers and is the largest city in the Kymenlaakso region. Kouvola is bordered by the municipalities of Hamina, Heinola, Iitti, Kotka, Lapinjärvi, Loviisa, Luumäki, Miehikkälä, Mäntyharju, Pyhtää and Savitaipale. Kouvola, which had population growth as late as the 1980s, has suffered a loss of migration since the 1990s. Over time, the loss has only deepened, so that at the end of the 2010s Kouvola was Finland's worst migration loss area. Natural demographics have also trended downward; in 2017, more than 450 more people died in the city than new ones were born. The reasons for the emigration are thought to be largely due to job losses in the region.

Phosphodiesterase-5 (PDE-5) Inhibitors as Emergent Environmental Contaminants
Erectile dysfunction (ED) is an increasing disorder [16], affects 25 to 35 million men over 18 years in Europe. Pharmaceuticals used to reduce this disorder act as phosphodiesterase-5 (PDE-5) inhibitors, a family of enzymes typically active in cyclic guanosine monophosphate (cGMP) degradation. The inhibition of PDE-5 results in the intracellular accumulation of cGMP, which plays a central role in signal transduction and regulates several physiological responses.

Sustainable Transport in Danube Region
Sustainability of transport systems is a key issue in transport. The main question is whether high levels of road and railway transport in areas along navigable waterways is an effective solution for this issue. The Danube waterway is an example. Cargo transport is mainly provided by road and railway transport. Air transport is not suitable for many types of goods. On the other hand, inland water transport provides many possibilities. It is suitable for the transport of bulk, general, and liquid cargo for longer distances. The Danube, which flows through Central and Eastern Europe, creates many possibilities for sustainable and environmentally friendly transport. It is the part of the waterway Rhine–Main–Danube that links the North and Black Seas and fifteen European countries.

Hurdles in Struggle against Nanoplastic Pollution
Plastics are considered one of the most serious environmental global concerns as they are ubiquitous and contribute to the build-up of pollution. Nanoplastics are also an emerging environmental concern as little is known about their generation, degradation, transformation, ageing, and transportation. Owing to their small size, nanoplastics can be trapped by filter-feeding organisms and can enter the food chain at an early stage.
