Climate Change and Its Impact on Crops
Plants are a highly advanced kingdom of living organisms on the earth. They survive under all climatic and weather variabilities, including low and high temperature, rainfall, radiation, less nutrients, and high salinity. Even though they are adapted to various environmental factors, which are variable, the performance of a crop will be compensated under sub/supra optimal conditions.

Nanoparticle Mechanisms for the Removal of Metals
Different natural and anthropogenic global events and activities such as urban settlements and industrial development have led to a build-up of numerous pollutants in the environment, creating problems for nature and human health. Metal(loid)s are defined as elements with a density of more than 4–5 g/cm3 that are toxic to humans even at low levels.

Platinum Group Elements Geochemistry and Mineralogy
Platinum (Pt), palladium (Pd), rhodium (Rh), iridium (Ir), ruthenium (Ru) and osmium (Os) are known as the platinum group elements (PGE). These metals are characterized by peculiar physical and chemical properties, such as high melting points, resistance to oxidation and corrosion, strong conductivity and ductility.

Development Status of CCUS in China
Carbon capture, utilization and storage (CCUS) has been applied in many countries and has proven to be a key carbon-reduction technology for the future. China currently emits the most carbon, and prior research findings indicate the high potential of CCUS technology to support the country’s emission-reduction process. China introduced CCUS technology at the end of the 20th century and has since implemented a series of related policies.

Agricultural Big Data and Machine Learning
Sustainable agriculture is currently being challenged under climate change scenarios since extreme environmental processes disrupt and diminish global food production. For example, drought-induced increases in plant diseases and rainfall caused a decrease in food production. Machine Learning and Agricultural Big Data are high-performance computing technologies that allow analyzing a large amount of data to understand agricultural production.

Sustainable Development and Environmental Kuznets Curve
Under the Kyoto Protocol which is international law since 2005, 15 EU member countries (the "EU-15") committed to reducing their collective emissions of a set of six greenhouse gases in the 2008-2012 period to 8% below the 1990 level. The EU established the first cap-and-trade system for carbon dioxide emissions in the world in 2005. This entry uses the effect of the European Union Emissions Trading System (EU ETS) on carbon dioxide (CO2) emissions for the European Union using a cross-country panel data set consisting of 12 countries extracted from the EU-15 from 1980 to 2009.

Biological Remediation of Polyfluorinated Compounds
Polyfluorinated compounds (PFCs) are a class of anthropogenic emerging persistent organic pollutants that consist of a fully fluorinated hydrophobic alkyl chain attached to a hydrophilic chain end group. The PFCs’ carbon–fluorine (C-F) bond, characterized by strong polarity and strength, make them possess peculiar physicochemical properties such as hydrophobicity and resistance to degradation by heat and acid. Their environmental occurrence particularly in drinking water samples and water receiving bodies, perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS) being the most detected PFCs is evident that they cannot be completely eradicated by conventional wastewater treatment plants (WWTPs). However, despite the PFCs' stable C-F bond, recent literature suggests that PFCs are susceptible to bioremediation by certain bacterial strain and plant species. A lot of work still needs to be done in the context of understanding the biodegradation pathway of PFOA and PFOS by both bacterial strain and plant species.

Wastewater Fecal Pollution Management
Global water scarcity has led to significant dependence on reclaimed or recycled water for potable uses. Effluents arising from human and animal gut microbiomes highly influence water quality. Wastewater pollution is, therefore, frequently monitored using bacterial indicators (BI).

Snow Line
The climatic snow line is the boundary between a snow-covered and snow-free surface. The actual snow line may adjust seasonally, and be either significantly higher in elevation, or lower. The permanent snow line is the level above which snow will lie all year.
