Meerkat National Park
Meerkat National Park is a large National Park in the Northern Cape, South Africa, that encompasses the Square Kilometre Array, MeerKAT and HERA telescopes. To ensure long term viability of the Karoo site for the MeerKAT and the SKA, and for other radio astronomy instruments, the South African Parliament passed the Astronomy Geographic Advantage Act, in 2007. The act gives the Minister of Science and Technology the authority to protect areas, through regulations, that are of strategic national importance for astronomy and related scientific endeavours. The park does not allow visitors. History The National Research Foundation purchased privately owned rangeland, removed livestock from the area and placed it under the protection of SANParks. In 2020, this park was declared in partnership with the National Research Foundation and the Square Kilometre Array project. It added 3.4% to South Africa's national parks. One of the objectives in creating the park was to increase t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Karoo Hoogland Local Municipality
Karoo Hoogland is an administrative area in the Namakwa District of Northern Cape in South Africa. Hoogland an Afrikaans word meaning "highland" and Karoo is a Khoi word meaning "hard" or "dry". The name reflects the area which has dry, arid and desert-like conditions. The municipality incorporates the towns of Williston, Fraserburg and Sutherland. Although the towns are separated by more than 100 km by road, they share many administrative tasks. Karoo Hoogland elected the first (and so far only) mayor from COPE, Jan Julies, in 2011, as a COPE- DA coalition took control of the council after the election of 18 May 2011. This lasted until the 2016 elections.

Hydrogen Epoch Of Reionization Array
The Hydrogen Epoch of Reionization Array (HERA) is a radio telescope dedicated to observing large scale structure during and prior to the epoch of reionization. HERA is a Square Kilometre Array (SKA) precursor instrument, intended to observe the early universe and to assist in the design of the full SKA. Along with MeerKAT, also in South Africa, and two radio telescopes in Western Australia, the Australian SKA Pathfinder (ASKAP) and the Murchison Widefield Array (MWA), the HERA is one of four precursors to the final SKA. It is located in the Meerkat National Park. Motivation There is a large time interval between the universe's recombination epoch ( z=1100) and the time (z = 7±1) after which intergalactic gas is largely reionized. Studies of the cosmic microwave background (CMB) have shown the structure of the universe at the start of this interval, and deep optical surveys such as the Sloan Digital Sky Survey show the structure after this time interval, but there is little d ...

Prosopis
''Prosopis'' is a genus of flowering plants in the family Fabaceae. It contains around 45 species of spiny trees and shrubs found in subtropical and tropical regions of the Americas, Africa, Western Asia, and South Asia. They often thrive in arid soil and are resistant to drought, on occasion developing extremely deep root systems. Their wood is usually hard, dense and durable. Their fruits are pods and may contain large amounts of sugar. The generic name means "burdock" in late Latin and originated in the Greek language. Selected species *Mesquites (southern United States, Mexico) ** '' Prosopis glandulosa'' Torr. – honey mesquite; ''Haas'' ( Cmiique Iitom) ** ''Prosopis laevigata'' ( Humb. & Bonpl. ex Willd.)

Climate Change
In common usage, climate change describes global warming—the ongoing increase in global average temperature—and its effects on Earth's climate system. Climate change in a broader sense also includes previous long-term changes to Earth's climate. The current rise in global average temperature is more rapid than previous changes, and is primarily caused by humans burning fossil fuels. Fossil fuel use, deforestation, and some agricultural and industrial practices increase greenhouse gases, notably carbon dioxide and methane. Greenhouse gases absorb some of the heat that the Earth radiates after it warms from sunlight. Larger amounts of these gases trap more heat in Earth's lower atmosphere, causing global warming. Due to climate change, deserts are expanding, while heat waves and wildfires are becoming more common. Increased warming in the Arctic has contributed to melting permafrost, glacial retreat and sea ice loss. Higher temperatures are also causing ...

Aloidendron Dichotomum
''Aloidendron dichotomum'', formerly ''Aloe dichotoma'', the quiver tree or kokerboom, is a tall, branching species of succulent plant, indigenous to Southern Africa, specifically in the Northern Cape province of South Africa, and parts of Southern Namibia. Naming Known as ''choje'' to the indigenous San people, the quiver tree gets its English common name from the San people practice of hollowing out the tubular branches of ''Aloidendron dichotomum'' to form quivers for their arrows. The specific epithet ''"dichotomum"'' refers to how the stems repeatedly branch into two ("dichotomous" branching) as the plant grows. This species was moved to the genus '' Aloidendron'' as ''Aloidendron dichotomum'' in 2013. Related species Three separate species, ''A. dichotomum'', '' A. pillansii'' and '' A. ramosissimum'' inhabit the same arid areas of the Richtersveld and the Namib Desert around the South African-Namibian border. The three have been given different ratings on the IUCN R ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nama Karoo
Nama Karoo is a xeric shrubland ecoregion located on the central plateau of South Africa and Namibia. It occupies most of the interior of the western half of South Africa and extends into the southern interior of Namibia. Climate The climate tends to be volatile and very harsh. Droughts are frequent with rain primarily falling in the summer. Rainfall can also be varied with it fluctuating between per year. Rainfall is known to be highly seasonal, peaking between December and March. It tends to decrease from the east to west and from north to south. The variability in the inter-annual rainfall also tends to increase with increasing aridity A region is arid when it severely lacks available water, to the extent of hindering or preventing the growth and development of plant and animal life. Regions with arid climates tend to lack vegetation and are called xeric or desertic. Most a .... Temperature variations as large as between day and night are common. Mean maximum tempe ...

Rangeland
Rangelands are grasslands, shrublands, woodlands, wetlands, and deserts that are grazed by domestic livestock or wild animals. Types of rangelands include tallgrass and shortgrass prairies, desert grasslands and shrublands, woodlands, savannas, chaparrals, steppes, and tundras. Rangelands do not include forests lacking grazable understory vegetation, barren desert, farmland, or land covered by solid rock, concrete and/or glaciers. Rangelands are distinguished from pasture lands because they grow primarily native vegetation, rather than plants established by humans. Rangelands are also managed principally with practices such as managed livestock grazing and prescribed fire rather than more intensive agricultural practices of seeding, irrigation, and the use of fertilizers. Grazing is an important use of rangelands but the term ''rangeland'' is not synonymous with ''grazingland''. Livestock grazing can be used to manage rangelands by harvesting forage to produce lives ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MeerKAT
MeerKAT, originally the Karoo Array Telescope, is a radio telescope consisting of 64 antennas in the Meerkat National Park, in the Northern Cape of South Africa. In 2003, South Africa submitted an expression of interest to host the Square Kilometre Array (SKA) Radio Telescope in Africa, and the locally designed and built MeerKAT was incorporated into the first phase of the SKA. MeerKAT was launched in 2018. Along with the Hydrogen Epoch of Reionization Array (HERA), also in South Africa, and two radio telescopes in Western Australia, the Australian SKA Pathfinder (ASKAP) and the Murchison Widefield Array (MWA), the MeerKAT is one of four precursors to the final SKA.

Square Kilometre Array
The Square Kilometre Array (SKA) is an intergovernmental international radio telescope project being built in Australia (low-frequency) and South Africa (mid-frequency). The combining infrastructure, the Square Kilometre Array Observatory (SKAO), and headquarters, are located at the Jodrell Bank Observatory in the United Kingdom. The SKA cores are being built in the southern hemisphere, where the view of the Milky Way galaxy is the best and radio interference at its least. Conceived in the 1990s, and further developed and designed by the late-2010s, when completed a total collecting area of approximately one square kilometre. It will operate over a wide range of frequencies and its size will make it 50 times more sensitive than any other radio instrument. If built as planned, it should be able to survey the sky more than ten thousand times faster than before. With receiving stations extending out to a distance of at least from a concentrated central core, it will exploit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
