Chumbe Island
Chumbe Island is a small privately owned island a few kilometres off the main island of Zanzibar, known for its ecological innovation and exceptional coral reefs. In 1992 the fringing reef west of Chumbe Island was officially closed to fishing, boating, and diving. In 1994, the island and its surrounding waters were declared the Chumbe Island Coral Park, which contains the Chumbe Reef Sanctuary and the Closed Forest Reserve. The park is run by the nonprofit private organization Chumbe Island Coral Park, Ltd. (CHICOP), which conducts marine research and small amounts of eco-tourism on the island. After the government of Tanzania established the protected area around the island and the fringing coral reef in 1994, the government gave the management rights to CHICOP, which is in charge of the CHICOP management plant. The Chumbe Reef Sanctuary is registered as a marine protected area by the World Conservation Monitoring Centre, and the first marine park in Tanzania The high qua ...

Zanzibar
Zanzibar (; ; ) is an insular semi-autonomous province which united with Tanganyika in 1964 to form the United Republic of Tanzania. It is an archipelago in the Indian Ocean, off the coast of the mainland, and consists of many small islands and two large ones: Unguja (the main island, referred to informally as Zanzibar) and Pemba Island. The capital is Zanzibar City, located on the island of Unguja. Its historic centre, Stone Town, is a World Heritage Site. Zanzibar's main industries are spices, raffia and tourism. In particular, the islands produce cloves, nutmeg, cinnamon, and black pepper. For this reason, the Zanzibar Archipelago, together with Tanzania's Mafia Island, are sometimes referred to locally as the "Spice Islands". Tourism in Zanzibar is a more recent activity, driven by government promotion that caused an increase from 19,000 tourists in 1985, to 376,000 in 2016. The islands are accessible via 5 ports and the Abeid Amani Karume International Airport, w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fresnel Lens
A Fresnel lens ( ; ; or ) is a type of composite compact lens developed by the French physicist Augustin-Jean Fresnel (1788–1827) for use in lighthouses. It has been called "the invention that saved a million ships." The design allows the construction of lenses of large aperture and short focal length without the mass and volume of material that would be required by a lens of conventional design. A Fresnel lens can be made much thinner than a comparable conventional lens, in some cases taking the form of a flat sheet. The simpler dioptric (purely refractive) form of the lens was first proposed by Count Buffon and independently reinvented by Fresnel. The ''catadioptric'' form of the lens, entirely invented by Fresnel, has outer elements that use total internal reflection as well as refraction; it can capture more oblique light from a light source and add it to the beam of a lighthouse, making the light visible from greater distances. Description The Fresnel lens redu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lighthouse Digest
''Lighthouse Digest'', a specialty magazine from FogHorn Publishing in East Machias, Maine, is about maritime history with particular attention to the preservation of lighthouses and their past. Though it is geared toward enthusiasts and antiquarians in the United States, it is also quoted commonly in more academic publications, and its editors have become a staple presence in scholarly circles. Editor Tim Harrison issued the first number in May, 1992. Scope Coverage includes historic and current lighthouse events and an events calendar for lighthouse activities around the United States and elsewhere. They publish a "Doomsday List" of Endangered lighthouses, and have helped save a number of at-risk lighthouses. They have been credited with uncovering many parts of lighthouse history that had been unknown, or which were thought to have been lost. Each issue carries articles and unusual lighthouse-related stories that, for the most part, cannot be found elsewhere, and many phot ...

Swahili Architecture
Swahili architecture is a term used to designate a whole range of diverse building traditions practiced or once practiced along the eastern and southeastern coasts of Africa. Rather than simple derivatives of Islamic architecture from the Arabic world, Swahili stone architecture is a distinct local product as a result of evolving social and religious traditions, environmental changes, and urban development. What is today seen as typically Swahili architecture is still very visible in the thriving urban centers of Mombasa, Lamu and Malindi in Kenya and Songo Mnara, Kilwa Kisiwani, and Zanzibar in Tanzania. The distribution of Swahili architecture and towns provides important clues about trade relationships among different regions and societal systems. Exotic ornament and design elements also connect the architecture of the Swahili coast to other Islamic port cities. Many of the classic mansions and palaces of the Swahili coast belonged to wealthy merchants and landowners, who pl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lighthouses In Tanzania
A lighthouse is a tower, building, or other type of physical structure designed to emit light from a system of lamps and lenses and to serve as a beacon for navigational aid, for maritime pilots at sea or on inland waterways. Lighthouses mark dangerous coastlines, hazardous shoals, reefs, rocks, and safe entries to harbors; they also assist in aerial navigation. Once widely used, the number of operational lighthouses has declined due to the expense of maintenance and has become uneconomical since the advent of much cheaper, more sophisticated and effective electronic navigational systems. History Ancient lighthouses Before the development of clearly defined ports, mariners were guided by fires built on hilltops. Since elevating the fire would improve the visibility, placing the fire on a platform became a practice that led to the development of the lighthouse. In antiquity, the lighthouse functioned more as an entrance marker to ports than as a warning signal for ree ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buildings And Structures In Zanzibar
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artistic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
