Lake Kariba is the world's largest man-made lake and reservoir by volume. It lies 1,300 kilometres upstream from the Indian Ocean, along the border between Zambia and Zimbabwe. Lake Kariba was filled between 1958 and 1963 following the completion of the Kariba Dam at its northeastern end, flooding the Kariba Gorge on the Zambezi River; the Zimbabwean town of Kariba was built for construction workers on the lake's dam, while some other settlements such as Binga village and Mlibizi in Zimbabwe and Siavonga and Sinazongwe in Zambia have grown up to house people displaced by the rising waters. Lake Kariba is over 223 kilometres up to 40 kilometres in width, it covers an area of 5,580 square kilometres mi) and its storage capacity is 185 cubic kilometres. The mean depth of the lake is 29 metres, it is the world's largest man-made reservoir by four times as large as the Three Gorges Dam. The enormous mass of water is believed to have caused induced seismicity in the seismically active region, including over 20 earthquakes of greater than 5 magnitude on the Richter scale.
The lake has several islands, including Maaze Island, Mashape Island, Chete Island, Sampa Karuma, Spurwing, Snake Island, Antelope Island, Bed Island, Chikanka. Before Lake Kariba was filled, the existing vegetation was burned, creating a thick layer of fertile soil on land that would become the lake bed; as a result, the ecology of Lake Kariba is vibrant. A number of fish species have been introduced to the lake, notably the sardine-like kapenta, which now supports a thriving commercial fishery. Other inhabitants of Lake Kariba include Nile hippopotami. Gamefish tigerfish, among the indigenous species of the Zambezi river system, now thrive on the kapenta, which in turn encourages tourism. Both Zambia and Zimbabwe are now attempting to develop the tourism industry along their respective coasts of Lake Kariba. Fish eagles and other water birds patrol the shorelines, as do large numbers of elephants and other big game species including Lion, Leopard, Buffalo and a myriad of smaller plains game species.
The southern Matusadona National Park was once a haven for Black and White Rhinoceros, but recent poaching activity has reduced their numbers. The portion of Lake Kariba which falls within Zimbabwe has been designated a Recreational Park within the Zimbabwe Parks and Wildlife Estate.

A semi-arid climate or steppe climate is the climate of a region that receives precipitation below potential evapotranspiration, but not as low as a desert climate. There are different kinds of semi-arid climates, depending on variables such as temperature, they give rise to different biomes. A more precise definition is given by the Köppen climate classification, which treats steppe climates as intermediates between desert climates and humid climates in ecological characteristics and agricultural potential. Semi-arid climates tend to support short or scrubby vegetation and are dominated by either grasses or shrubs. To determine if a location has a semi-arid climate, the precipitation threshold must first be determined. Finding the precipitation threshold involves first multiplying the average annual temperature in °C by 20 adding 280 if 70% or more of the total precipitation is in the high-sun half of the year, or 140 if 30%–70% of the total precipitation is received during the applicable period, or 0 if less than 30% of the total precipitation is so received.
If the area's annual precipitation is less than the threshold but more than half the threshold, it is classified as a BS. Furthermore, to delineate "hot semi-arid climates" from "cold semi-arid climates", there are three used isotherms: Either a mean annual temperature of 18°C, or a mean temperature of 0°C or −3°C in the coldest month, so that a location with a "BS" type climate with the appropriate temperature above whichever isotherm is being used is classified as "hot semi-arid", a location with the appropriate temperature below the given isotherm is classified as "cold semi-arid". Hot semi-arid climates tend to be located in the 20s and 30s latitudes of the in proximity to regions with a tropical savanna or a humid subtropical climate; these climates tend to have hot, sometimes hot and warm to cool winters, with some to minimal precipitation. Hot semi-arid climates are most found around the fringes of subtropical deserts. Hot semi-arid climates are most found in Africa and South Asia. In Australia, a large portion of the Outback surrounding the central desert regions lies within the hot semi-arid climate region.
In South Asia, both India and sections of Pakistan experiences the seasonal effects of monsoons and feature short but well-defined wet seasons, but is not sufficiently wet overall to qualify as a tropical savanna climate. Hot semi-arid climates can be found in Europe, parts of North America, such as in Mexico, areas of the Southwestern United States, sections of South America such as the sertão, the Gran Chaco, on the poleward side of the arid deserts, where they feature a Mediterranean precipitation pattern, with rainless summers and wetter winters. Cold semi-arid climates tend to be located in elevated portions of temperate zones bordering a humid continental climate or a Mediterranean climate, they are found in continental interiors some distance from large bodies of water. Cold semi-arid climates feature warm to hot dry summers, though their summers are not quite as hot as those of hot semi-arid climates. Unlike hot semi-arid climates, areas with cold semi-arid climates tend to have cold winters.
These areas see some snowfall during the winter, though snowfall is much lower than at locations at similar latitudes with more humid climates. Areas featuring cold semi-arid climates tend to have higher elevations than areas with hot semi-arid climates, tend to feature major temperature swings between day and night, sometimes by as much as 20 °C or more in that time frame; these large diurnal temperature variations are seen in hot semi-arid climates. Cold semi-arid climates at higher latitudes tend to have dry winters and wetter summers, while cold semi-arid climates at lower latitudes tend to have precipitation patterns more akin to subtropical climates, with dry summers wet winters, wetter springs and autumns. Cold semi-arid climates are most found in Asia and North America. However, they can be found in Northern Africa, South Africa, sections of South America and sections of interior southern Australia and New Zealand. In climate classification, three isotherms means that delineate between hot and cold semi-arid climates — the 18°C average annual temperature or that of the coldest month, the warm side of the isotherm of choice defining a BSh climate from the BSk on the cooler side.
As a result of this, some areas can have climates that are classified as hot or cold semi-arid depending on the isotherm used. One such location is San Diego, which has cool summers for the latitude due to prevailing winds off the ocean but mild winters.

Tourism is travel for pleasure or business. Tourism may be international, or within the traveller's country; the World Tourism Organization defines tourism more in terms which go "beyond the common perception of tourism as being limited to holiday activity only", as people "traveling to and staying in places outside their usual environment for not more than one consecutive year for leisure and not less than 24 hours and other purposes". Tourism can be domestic or international, international tourism has both incoming and outgoing implications on a country's balance of payments. Tourism suffered as a result of a strong economic slowdown of the late-2000s recession, between the second half of 2008 and the end of 2009, the outbreak of the H1N1 influenza virus, but recovered. International tourism receipts grew to US$1.03 trillion in 2005, corresponding to an increase in real terms of 3.8% from 2010. International tourist arrivals surpassed the milestone of 1 billion tourists globally for the first time in 2012, emerging markets such as China and Brazil had increased their spending over the previous decade.
The ITB Berlin is the world's leading tourism trade fair. Global tourism accounts for ca. 8% of global greenhouse gas emissions. The word tourist was used in 1772 and tourism in 1811, it is formed from the word tour, derived from Old English turian, from Old French torner, from Latin tornare. Tourism has become an important source of income for many regions and entire countries; the Manila Declaration on World Tourism of 1980 recognized its importance as "an activity essential to the life of nations because of its direct effects on the social, cultural and economic sectors of national societies and on their international relations."Tourism brings large amounts of income into a local economy in the form of payment for goods and services needed by tourists, accounting as of 2011 for 30% of the world's trade in services, for 6% of overall exports of goods and services. It generates opportunities for employment in the service sector of the economy associated with tourism; the hospitality industries which benefit from tourism include transportation services.
This is in addition to goods bought by tourists, including souvenirs. On the flip-side, tourism can degrade sour relationships between host and guest. In 1936, the League of Nations defined a foreign tourist as "someone traveling abroad for at least twenty-four hours", its successor, the United Nations, amended this definition in 1945, by including a maximum stay of six months. In 1941, Hunziker and Kraft defined tourism as "the sum of the phenomena and relationships arising from the travel and stay of non-residents, insofar as they do not lead to permanent residence and are not connected with any earning activity." In 1976, the Tourism Society of England's definition was: "Tourism is the temporary, short-term movement of people to destinations outside the places where they live and work and their activities during the stay at each destination. It includes movements for all purposes." In 1981, the International Association of Scientific Experts in Tourism defined tourism in terms of particular activities chosen and undertaken outside the home.
In 1994, the United Nations identified three forms of tourism in its Recommendations on Tourism Statistics: Domestic tourism, involving residents of the given country traveling only within this country Inbound tourism, involving non-residents traveling in the given country Outbound tourism, involving residents traveling in another countryThe terms tourism and travel are sometimes used interchangeably. In this context, travel implies a more purposeful journey; the terms tourism and tourist are sometimes used pejoratively, to imply a shallow interest in the cultures or locations visited. By contrast, traveler is used as a sign of distinction; the sociology of tourism has studied the cultural values underpinning these distinctions and their implications for class relations. International tourist arrivals reached 1.035 billion in 2012, up from over 996 million in 2011, 952 million in 2010. In 2011 and 2012, international travel demand continued to recover from the losses resulting from the late-2000s recession, where tourism suffered a strong slowdown from the second half of 2008 through the end of 2009.
After a 5% increase in the first half of 2008, growth in international tourist arrivals moved into negative territory in the second half of 2008, ended up only 2% for the year, compared to a 7% increase in 2007. The negative trend intensified during 2009, exacerbated in some countries due to the outbreak of the H1N1 influenza virus, resulting in a worldwide decline of 4.2% in 2009 to 880 million international tourists arrivals, a 5.7% decline in international tourism receipts. The World Tourism Organization reports the following ten destinations as the most visited in terms of the number of international travelers in 2017. International tourism receipts grew to US$1.26 Trillion in 2015, corresponding to an increase in real terms of 4.4% from 2014. The World Tourism Organization reports the following entities as the top ten tourism earners for the year 2015: The World Tourism Organizati
Zambia the Republic of Zambia, is a landlocked country in south-central Africa. It neighbours the Democratic Republic of the Congo to the north, Tanzania to the north-east, Malawi to the east, Mozambique to the southeast and Botswana to the south, Namibia to the southwest, Angola to the west; the capital city is Lusaka, located in the south-central part of Zambia. The population is concentrated around Lusaka in the south and the Copperbelt Province to the northwest, the core economic hubs of the country. Inhabited by Khoisan peoples, the region was affected by the Bantu expansion of the thirteenth century. After visits by European explorers in the eighteenth century, the region became the British protectorates of Barotziland-North-Western Rhodesia and North-Eastern Rhodesia towards the end of the nineteenth century; these were merged in 1911 to form Northern Rhodesia. For most of the colonial period, Zambia was governed by an administration appointed from London with the advice of the British South Africa Company.
On 24 October 1964, Zambia became independent of the United Kingdom and prime minister Kenneth Kaunda became the inaugural president. Kaunda's socialist United National Independence Party maintained power from 1964 until 1991. Kaunda played a key role in regional diplomacy, cooperating with the United States in search of solutions to conflicts in Rhodesia and Namibia. From 1972 to 1991 Zambia was a one-party state with the UNIP as the sole legal political party under the motto "One Zambia, One Nation". Kaunda was succeeded by Frederick Chiluba of the social-democratic Movement for Multi-Party Democracy in 1991, beginning a period of social-economic growth and government decentralisation. Levy Mwanawasa, Chiluba's chosen successor, presided over Zambia from January 2002 until his death in August 2008, is credited with campaigns to reduce corruption and increase the standard of living. After Mwanawasa's death, Rupiah Banda presided as Acting President before being elected President in 2008. Holding office for only three years, Banda stepped down after his defeat in the 2011 elections by Patriotic Front party leader Michael Sata.
Sata died on 28 October 2014. Guy Scott served as interim president until new elections were held on 20 January 2015, in which Edgar Lungu was elected as the sixth President. In 2010, the World Bank named Zambia one of the world's fastest economically reformed countries; the Common Market for Eastern and Southern Africa is headquartered in Lusaka. The territory of what is now Zambia was known as Northern Rhodesia from 1911, it was renamed Zambia at independence in 1964. The new name of Zambia was derived from the Zambezi river; the area of modern Zambia is known to have been inhabited by the Khoisan until around AD 300, when migrating Bantu began to settle around these areas. These early hunter-gatherer groups were either annihilated or absorbed by subsequent more organised Bantu groups. Archaeological excavation work on the Zambezi Valley and Kalambo Falls show a succession of human cultures. In particular, ancient camping site tools near the Kalambo Falls have been radiocarbon dated to more than 36,000 year ago.
The fossil skull remains of Broken Hill Man, dated between 300,000 and 125,000 years BC, further shows that the area was inhabited by early humans. The early history of the peoples of modern Zambia can only be gleaned from knowledge passed down by generations through word of mouth. In the 12th century, waves of Bantu-speaking immigrants arrived during the Bantu expansion. Among them, the Tonga people were the first to settle in Zambia and are believed to have come from the east near the "big sea"; the Nkoya people arrived early in the expansion, coming from the Luba–Lunda kingdoms in the southern parts of the modern Democratic Republic of the Congo and northern Angola, followed by a much larger influx between the late 12th and early 13th centuries To the east, the Maravi Empire spanning the vast areas of Malawi and parts of modern northern Mozambique began to flourish under Kalonga. At the end of the 18th century, some of the Mbunda migrated to Barotseland, Mongu upon the migration of among others, the Ciyengele.
The Aluyi and their leader, the Litunga Mulambwa valued the Mbunda for their fighting ability. In the early 19th century, the Nsokolo people settled in the Mbala district of Northern Province. During the 19th century, the Ngoni and Sotho peoples arrived from the south. By the late 19th century, most of the various peoples of Zambia were established in their current areas; the earliest European to visit the area was the Portuguese explorer Francisco de Lacerda in the late 18th century. Lacerda led an expedition from Mozambique to the Kazembe region in Zambia, died during the expedition in 1798; the expedition was from on led by his friend Francisco Pinto. This territory, located between Portuguese Mozambique and Portuguese Angola, was claimed and explored by Portugal in that period. Other European visitors followed in the 19th century; the most prominent of these was David Livingstone, who had a vision of ending the slave trade through the "3 Cs": Christianity and Civilization. He was the first European to see the magnificent waterfalls on the Zambezi River in 1855, naming them the Victoria Falls after Queen Victoria of the United Kingdom.
He described them thus: "Scenes so lovely must have been gazed upon by angels in their flight". Locally the falls are known as "Mosi-o-Tunya" or "thunder
Southern Province, Zambia
Southern Province is one of Zambia's ten provinces, home to Zambia's premier tourist attraction, Mosi-oa-Tunya, shared with Zimbabwe. The centre of the province, the Southern Plateau, has the largest area of commercial farmland of any Zambian province, produces most of the maize crop; the Zambezi River is the province's southern border, Lake Kariba, formed by the Kariba Dam, lies along the province's south-eastern edge. The eastern border is the Kariba Gorge and Zambezi, the north-east border is the Kafue River and its gorge, dividing it from Lusaka Province; the Kafue Flats lie within the province's northern border with Central Province. In the north west lies part of the famous Kafue National Park, the largest in Zambia, the lake formed by the Itezhi-Tezhi Dam; the south-western border with Western Province runs through the teak forests around Mulobezi which once supported a commercial timber industry and for which the Mulobezi Railway was built. The provincial capital is Choma; until 2011 the provincial capital was Livingstone City.
The Batonga are the largest ethnic group in the Province. A rail line and the Lusaka-Livingstone road forms the principal transport axis of the province, running through its centre and its farming towns: Kalomo, Pemba and Mazabuka. In addition to maize, other commercially important activities include sugar cane plantations at the edge of the Kafue Flats, cattle ranching. Southern Province has the only large source of fossil fuel in Zambia, the Maamba coal mine in the Zambezi valley, served by a branch line of the railway; as per the 2010 Zambian census, Southern Province had a population of 1,589,926 accounting to 12.08% of the total Zambian population of 13,092,666. There were 779,659 males and 810,267 females, making the sex ratio to 1,039 for every 1,000 males, compared to the national average of 1,028; the literacy rate stood at 71.20% against a national average of 70.2%. The rural population constituted 75.33%, while the urban population was 24.67%. The total area of the province was 85,283 km2 and the population density was 18.60 per km2.
The population density during 2000 Zambian census stood at 18.60. The decadal population growth of the province was 2.80%. The median age in the province at the time of marriage was 20.6. The average household size was 5.4, with the families headed by females being 4.6 and 5.7 for families headed by men. The total eligible voters in the province was 64.10%. The unemployment rate of the province was 12.10%. The total fertility rate was 6.1, complete birth rate was 6.2, crude birth rate was 37.0, child women population at birth was 807, general fertility rate was 160, gross reproduction rate was 2.5 and net reproduction rate was 1.8. The total labour force constituted 55.00% of the total population. Out of the labour force,64.1% were men and 46.7% women. The annual growth rate of labour force was 4.4%. Tonga was the most spoken language with 74.70% speaking it. Albinism is a condition where the victims do not have any pigment in hair or eyes; the total population in the province with the condition stood at 3,068.
The life expectancy at birth stood at 56 compared to the national average of 51. Agriculture is the primary economic activity in Southern Province with a mix of small holder and commercial maize farms across the province. Compared to other major agricultural regions, such as Eastern Province, Southern Province has more abundant land and access to water, but receives less rainfall. Southern Province is home to the "Sweetest Town in Zambia", where sugarcane farming and sugar processing are a major business; the total area of crops planted during the year 2014 in the province was 360,160.32 hectares which constituted 18.98% of the total area cultivated in Zambia. The net production stood at 688,122 metric tonnes, which formed 16.89% of the total agricultural production in the country. Sorghum was the major crop in the province with 4,695 metric tonnes, constituting 40.62% of the national output. Mazabuka grows 90% of sugar grown in Zambia with an estimated 430 tons produced annually. Sugarcane fields in Mazabuka are among the most productive in the world by hectare and low production costs allow production to compete on international markets.
Around 60 % of sugar is exported to other markets. However, the export industry is limited due to high transport costs linking processed sugar to export markets. Nationally, the sugar industry in Mazabuka contributes to around 4% of GDP each year; the sugar industry in Mazabuka made international news in 2013 when it was discovered that Zambia Sugar, the biggest sugar company in the country, had paid nothing in corporate taxes to Zambia in the previous 5 years. Southern Province and Eastern Province are the two primary breadbaskets of Zambia. Southern Province produces more than 600,000 metric tons of maize each year from a combination of commercial, which are unique to Southern Province, smallholder farms. Despite poor rains in recent years and a strong El Nino weather cycle in 2016, Zambian maize output has been predicted to continue to grow. Growth in Southern Province and across the country has allowed Zambia to remain a net-exporter of maize to food insecure neighboring countries, such as Zimbabwe and Malawi which have been hit more by the weather.
As of 2004, the province had 995 basic schools, 45 high schools and the number of school children out of school in ages between 7 and 15 stood at 995. The unemployment rate was 7 per cent and the general unemployment rate for youth stood at 6 per cent as of 2008; the province had 50 doctors as of 2005. There were 344 Malaria incidence for every 1,000 people in the province as of 2005 and there were 12,403 AIDS death as of 2010. Southern Province is bordered along Zimbabwe in the south divided by Victoria Fall
Integrated Authority File
The Integrated Authority File or GND is an international authority file for the organisation of personal names, subject headings and corporate bodies from catalogues. It is used for documentation in libraries and also by archives and museums; the GND is managed by the German National Library in cooperation with various regional library networks in German-speaking Europe and other partners. The GND falls under the Creative Commons Zero licence; the GND specification provides a hierarchy of high-level entities and sub-classes, useful in library classification, an approach to unambiguous identification of single elements. It comprises an ontology intended for knowledge representation in the semantic web, available in the RDF format; the Integrated Authority File became operational in April 2012 and integrates the content of the following authority files, which have since been discontinued: Name Authority File Corporate Bodies Authority File Subject Headings Authority File Uniform Title File of the Deutsches Musikarchiv At the time of its introduction on 5 April 2012, the GND held 9,493,860 files, including 2,650,000 personalised names.
There are seven main types of GND entities: LIBRIS Virtual International Authority File Information pages about the GND from the German National Library Search via OGND Bereitstellung des ersten GND-Grundbestandes DNB, 19 April 2012 From Authority Control to Linked Authority Data Presentation given by Reinhold Heuvelmann to the ALA MARC Formats Interest Group, June 2012
Virtual International Authority File
The Virtual International Authority File is an international authority file. It is a joint project of several national libraries and operated by the Online Computer Library Center. Discussion about having a common international authority started in the late 1990s. After a series of failed attempts to come up with a unique common authority file, the new idea was to link existing national authorities; this would present all the benefits of a common file without requiring a large investment of time and expense in the process. The project was initiated by the US Library of Congress, the German National Library and the OCLC on August 6, 2003; the Bibliothèque nationale de France joined the project on October 5, 2007. The project transitioned to being a service of the OCLC on April 4, 2012; the aim is to link the national authority files to a single virtual authority file. In this file, identical records from the different data sets are linked together. A VIAF record receives a standard data number, contains the primary "see" and "see also" records from the original records, refers to the original authority records.
The data are available for research and data exchange and sharing. Reciprocal updating uses the Open Archives Initiative Protocol for Metadata Harvesting protocol; the file numbers are being added to Wikipedia biographical articles and are incorporated into Wikidata. VIAF's clustering algorithm is run every month; as more data are added from participating libraries, clusters of authority records may coalesce or split, leading to some fluctuation in the VIAF identifier of certain authority records.
