Dugout Canoes
A dugout canoe or simply dugout is a boat made from a hollowed-out tree. Other names for this type of boat are logboat and monoxylon. ''Monoxylon'' (''μονόξυλον'') (pl: ''monoxyla'') is Greek''mono-'' (single) + '' ξύλον xylon'' (tree)and is mostly used in classic Greek texts. In German, they are called Einbaum ("one tree" in English). Some, but not all, pirogues are also constructed in this manner. Dugouts are the oldest boat type archaeologists have found, dating back about 8,000 years to the Neolithic Stone Age. This is probably because they are made of massive pieces of wood, which tend to preserve better than others, such as bark canoes. Construction Construction of a dugout begins with the selection of a log of suitable dimensions. Sufficient wood must be removed to make the vessel relatively light in weight and buoyant, yet still strong enough to support the crew and cargo. Specific types of wood were often preferred based on their strength, durability, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boats At The Shore Of The Malawi Lake
A boat is a watercraft of a large range of types and sizes, but generally smaller than a ship, which is distinguished by its larger size or capacity, its shape, or its ability to carry boats. Small boats are typically used on inland waterways such as rivers and lakes, or in protected coastal areas. However, some boats (such as whaleboats) were intended for offshore use. In modern Navy, naval terms, a boat is a vessel small enough to be carried aboard a ship. Boats vary in proportion and construction methods with their intended purpose, available materials, or local traditions. Canoes have been used since prehistoric times and remain in use throughout the world for transportation, fishing, and sport. Fishing boats vary widely in style partly to match local conditions. Pleasure boat, Pleasure craft used in boating, recreational boating include ski boats, Pontoon (boat), pontoon boats, and sailboats. House boats may be used for vacationing or long-term residence.

Trade
Trade involves the transfer of goods and services from one person or entity to another, often in exchange for money. Economists refer to a system or network that allows trade as a market. Traders generally negotiate through a medium of credit or exchange, such as money. Though some economists characterize barter (i.e. trading things without the use of money) as an early form of trade, money was invented before written history began. Consequently, any story of how money first developed is mostly based on conjecture and logical inference. Letters of credit, paper money, and non-physical money have greatly simplified and promoted trade as buying can be separated from selling, or earning. Trade between two traders is called bilateral trade, while trade involving more than two traders is called multilateral trade. In one modern view, trade exists due to specialization and the division of labor, a predominant form of economic activity in which individuals and groups ...

Niger River
The Niger River ( ; ) is the main river of West Africa, extending about . Its drainage basin is in area. Its source is in the Guinea Highlands in south-eastern Guinea near the Sierra Leone border. It runs in a crescent shape through Mali, Niger, on the border with Benin and then through Nigeria, discharging through a massive River delta, delta, known as the Niger Delta, into the Gulf of Guinea in the Atlantic Ocean. The Niger is the third-longest river in Africa, exceeded by the Nile and the Congo River. Its main tributary is the Benue River.

Tributaries
A tributary, or an ''affluent'', is a stream or river that flows into a larger stream ('' main stem'' or ''"parent"''), river, or a lake. A tributary does not flow directly into a sea or ocean. Tributaries, and the main stem river into which they flow, drain the surrounding drainage basin of its surface water and groundwater, leading the water out into an ocean, another river, or into an endorheic basin. The Irtysh is a chief tributary of the Ob river and is also the longest tributary river in the world with a length of . The Madeira River is the largest tributary river by volume in the world with an average discharge of . A confluence, where two or more bodies of water meet, usually refers to the joining of tributaries. The opposite to a tributary is a distributary, a river or stream that branches off from and flows away from the main stream. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cargo
In transportation, cargo refers to goods transported by land, water or air, while freight refers to its conveyance. In economics, freight refers to goods transported at a freight rate for commercial gain. The term cargo is also used in case of goods in the cold-chain, because the perishable inventory is always in transit towards a final end-use, even when it is held in cold storage or other similar climate-controlled facilities, including warehouses. Multi-modal container units, designed as reusable carriers to facilitate unit load handling of the goods contained, are also referred to as cargo, especially by shipping lines and logistics operators. When empty containers are shipped each unit is documented as a cargo and when goods are stored within, the contents are termed containerized cargo. Similarly, aircraft ULD boxes are also documented as cargo, with an associated packing list of the items contained within. Description Marine Seaport terminals handle a wide ra ...

Paddling
Paddling, in regard to waterborne transport, is the act of propelling a human-powered watercraft using at least one hand-held paddle. The paddle, which consists of one or two blades joined to a shaft, is also used to steer the vessel via generating a difference in propulsion between the two broadside (naval), sides of the watercraft. The paddle is not connected to the boat, unlike in rowing where the oar is attached to the boat. In paddling sports such as canoeing and kayaking, the characteristics that are most important include "dynamic balance, core stability, pulling power, speed, endurance, stature, and rhythm". Canoeing Canoeing is the activity of paddling a canoe for leisure, navigation or exploration. In America the term refers exclusively to using one or more single blades or paddles to propel a canoe. In the United Kingdom and some other countries in Europe however, canoeing is also used to refer to kayaking, and canoeing is then often called ''Canadian (canoe), Canadia ...

Watercraft
A watercraft or waterborne vessel is any vehicle designed for travel across or through water bodies, such as a boat, ship, hovercraft, submersible or submarine. Types Historically, watercraft have been divided into two main categories. *Rafts, which gain their buoyancy from the fastening together of components that are each buoyant in their own right. Generally, a raft is a "flow through" structure, whose users would have difficulty keeping dry as it passes through waves. Consequently, apart from short journeys (such as a river crossing), their use is confined to warmer regions (roughly 40° N to 40° S). Outside this area, use of rafts at sea is impracticable due to the risks of exposure to the crew. *Boats and ships, which float by having the submergeable part of their structure exclude water with a waterproof surface, so creating a space that contains air, as well as cargo, passengers, crew, etc. In total, this structure weighs less than the water that would occupy the sa ...

Goods
In economics, goods are anything that is good, usually in the sense that it provides welfare or utility to someone. Alan V. Deardorff, 2006. ''Terms Of Trade: Glossary of International Economics'', World Scientific. Online version: Deardorffs' Glossary of International Economics"good" an Goods can be contrasted with bads, i.e. things that provide negative value for users, like chores or waste. A bad lowers a consumer's overall welfare. Economics focuses on the study of economic goods, i.e. goods that are scarce; in other words, producing the good requires expending effort or resources. Economic goods contrast with free goods such as air, for which there is an unlimited supply.Samuelson, P. Anthony., Samuelson, W. (1980). Economics. 11th ed. / New York: McGraw-Hill. Goods are the result of the Secondary sector of the economy which involves the transformation of raw materials or intermediate goods into goods.

Nok Culture
The Nok culture is a population whose material remains are named after the Ham people, Ham village of Nok in Southern Kaduna, southern Kaduna State of Nigeria, where their terracotta sculptures were first discovered in 1928. The Nok people and the Gajiganna people may have migrated from the Central Sahara, along with pearl millet and pottery, and diverged prior to arriving in the northern region of modern-day Nigeria. This may have led to their respective settlements in the regions of Gajiganna and Nok. Nok people may have also migrated from the West African Sahel to the region of Nok. Nok culture may have emerged in 1500 BCE and continued to persist until 1 BCE. Nok people may have developed Nok culture#Sculptures, terracotta sculptures, through large-scale economic production, as part of a complex funerary culture that may have included practices such as feasting. The earliest Nok terracotta sculptures may have developed in 900 BCE. Some Nok terracotta sculptures portray figu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Francophone
The Francophonie or Francophone world is the whole body of people and organisations around the world who use the French language regularly for private or public purposes. The term was coined by Onésime Reclus in 1880 and became important as part of the conceptual rethinking of cultures and geography in the late 20th century. When used to refer to the French-speaking world, the Francophonie encompasses the countries and territories where French is official or serves as an administrative or major secondary language, which spans 50 countries and dependencies across all inhabited continents. The vast majority of these are also member states of the (OIF), a body uniting countries where French is spoken and taught. Denominations Francophonie, francophonie and francophone space are syntagmatic. This expression is relevant to countries which speak French as their national language, may it be as a mother language or a secondary language. These expressions are sometimes misund ...
