Definition: 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.

Definition: Chile is a country that is highly dependent on importing energy, particularly fossil hydrocarbons, even though it possesses a variety of energy resources that are relatively well distributed. Around 24% of the country’s power grid comes from forest-based biomass, with firewood being the most-used energy source, mainly for heating and cooking purposes: 97% of firewood is used for heating, and the other 3% is used for domestic water heating and, in some cases, for cooking food. Given that firewood is used by thousands of people during the year, wood burning has had severe social and environmental consequences in densely populated cities such as Temuco. These consequences are mainly due to biomass combustion, which is an important source of particulate matter stemming from the incomplete combustion of components like cellulose, hemicellulose, and lignin, in addition to temperature-produced changes caused by combustion from uncontrolled sources.

Definition: Blockchain is an open-source technology that excludes the traditional third parties by relying on collective verification, thus offering a great alternative in terms of costs, traceability, security, and speed. When two financial entities such as banks receive a request to transfer money from one account to another, they have to update the balances of their respective customers. This costly and time-consuming coordination and synchronization exercise can be simplified on a blockchain by using a single ledger of transactions reflecting a single version of records instead of two different databases. Blockchain technology offers a myriad of value through a frictionless process of immutable and transparent records and through converting assets into digital tokens (i.e., tokenization) with smart contracts.

Definition: Global drylands are expanding due to climate change, threatening global food security (FS), especially in Africa. Eastern Africa has 328 million hectares of drylands, 6% of which is covered by crops; most crops are rained on, and irrigated land accounts for only 5 million hectares (22%). In Ethiopia, 75% of the landmass is categorized as dryland, the majority of which experiences high risks of land degradation, natural hazards, and water and food shortages.

Definition: The existing state of the world climate creates the need for an educational programme that incorporates effective proposals for the environment that can be practically implemented. The present environmental education literature has changed due to new study paradigms. Understanding how students relate to nature, how their personal beliefs and behaviours are influenced, and how their actions are affected can provide an increased understanding of how they can contribute meaningfully to global objectives. This paper aims to analyse educational research papers published in the area of environmental art education in order to find the factor with the greatest effect and illuminate how they can help to improve the measures implemented.

Definition: Fermented foods and beverages are generally defined as products made by microbial organisms and enzymatic conversions of major and minor food components. Further to the commonly-recognized effects of nutrition on the digestive health and well-being, there is now strong evidence for the impact of fermented foods and beverages, produced or preserved by the action of microorganisms, on general health, namely their significance on the gut microbiota balance and brain functionality.

Definition: 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.
