Energy Emissions Reduction in South African National Parks
South African National Parks (SANParks) aimed to contribute to national targets by reducing their fossil-fuel-generated energy consumption by 2% per year until achieving carbon neutrality. SANParks achieved 1% year-on-year energy emissions reduction through its renewable base; however, an ambitious target of 8% would be appropriate for a 1.5 °C future based on the energy scenario planning.

Endangered Species Recovery Plan
An endangered species recovery plan, also known as a species recovery plan, species action plan, species conservation action, or simply recovery plan, is a document describing the current status, threats and intended methods for increasing rare and endangered species population sizes. Recovery plans act as a foundation from which to build a conservation effort to preserve animals which are under threat of extinction.

Khatt Shebib
The Khatt Shebib is an ancient wall in Southern Jordan. The remains of the wall are 150 km long, making it the longest linear archaeological site in Jordan. The archaeological ruins were first identified by British diplomat Sir Alec Kirkbride in 1948. Ever since, a range of disciplines, including archaeologists, scientists and anthropologists, have studied the wall. The date of the Khatt Shebib's construction is still unknown, however, it has been widely debated by archaeologists. This is evident as some archaeologists argue that the wall was built in the Iron Age, whilst others argue it was constructed in the Nabataean period. The Khatt Shebib was built and used by the semi-nomadic Bedouin people, whose livelihoods consisted of herding and farming in the harsh, arid environment of the Jordan desert. The Khatt Shebib was not used for military purposes rather the ancient wall served as a border. At the time of its construction, the wall was approximately no taller than a meter and a half high. Due to various threats to the integrity of the wall, including climatic issues and growing population pressures, the wall is significantly smaller. The Khatt Shebib has gained increasing attention amongst archaeologists. The leading method of studying the wall is aerial archaeology and multiple international archaeological organisation have established projects in order to understand and discover more about the wall.

Canadian Goldenrod
Perennial herb Solidago canadensis L. (Asteraceae: Astereae), originating in North America, was brought and introduced into middle Europe as an ornamental, schizanthus, and melliferous plant in the middle of the 18th century. In the end, it unintentionally spread from the gardens to the natural environment.

Majorcan Cartographic School
"Majorcan cartographic school" is the term coined by historians to refer to the collection of predominantly Jewish cartographers, cosmographers and navigational instrument-makers and some Christian associates that flourished in Majorca in the 13th, 14th and 15th centuries until the expulsion of the Jews. The label is usually inclusive of those who worked in Catalonia. The Majorcan school is frequently contrasted with the contemporary Italian cartography school.

Gulf of Mexico Basin
The formation of the Gulf of Mexico, an oceanic rift basin located between North America and the Yucatan Block, was preceded by the breakup of the Supercontinent Pangaea in the Late-Triassic, weakening the lithosphere. Rifting between the North and South American plates continued in the Early-Jurassic, approximately 160 million years ago, and formation of the Gulf of Mexico, including subsidence due to crustal thinning, was complete by 140 Ma. Stratigraphy of the basin, which can be split into several regions, includes sediments deposited from the Jurassic through the Holocene, currently totaling a thickness between 15 and 20 kilometers.

Metal(loid) Bioremediation by Microbial Polymers
Environmental pollution arising from metal(loid)s is a result of industrialization, and has led to serious health issues. Conventional methods of metal(loid) removal often result in generation of secondary waste which is toxic to the environment. Bioremediation in combination with physicochemical techniques offer an excellent and effective means of removal. The use of secondary metabolites and extracellular polymers produced by microorganisms is an effective procedure employed in metal(loid) sequestration and reduction in toxicity of contaminated environments. These biopolymers have different chemical structures and have shown varied selectivity to different metal(loid)s.

Landscape Connectivity
Landscape connectivity in ecology is, broadly, "the degree to which the landscape facilitates or impedes movement among resource patches". Alternatively, connectivity may be a continuous property of the landscape and independent of patches and paths. Connectivity includes both structural connectivity (the physical arrangements of disturbance and/or patches) and functional connectivity (the movement of individuals across contours of disturbance and/or among patches). Functional connectivity includes actual connectivity (requires observations of individual movements) and potential connectivity in which movement paths are estimated using the life-history data. The degree to which a landscape is connected determines the amount of dispersal there is among patches, which influences gene flow, local adaptation, extinction risk, colonization probability, and the potential for organisms to move as they cope with climate change.
