Forestry In Taiwan
Forestry in Taiwan was historically a significant industry. The logging of most of Taiwan's old growth forest has led to the sunset of the industry with remaining stands protected by law. Illegal logging remains a significant threat, especially to the oldest and most valuable trees. History Major commercial forestry in Taiwan began during the Japanese colonial period with most forestry products being shipped back to Japan. Due to the remoteness and inaccessibility of many regions some of Taiwan's large trees survived, in 2022 a team of researchers identified 941 trees taller than 65m. Camphor Camphor has been produced as a forest product for centuries, condensed from the vapor given off by the roasting of wood chips cut from the relevant trees, and later by passing steam through the pulverized wood and condensing the vapors. By the early 19th century most camphor tree reserves had been depleted with the remaining large stands in Japan and Taiwan with Taiwanese production greatly ex ...

Old Growth Forest
An old-growth forestalso termed primary forest, virgin forest, late seral forest, primeval forest, or first-growth forestis a forest that has attained great age without significant disturbance, and thereby exhibits unique ecological features, and might be classified as a climax community. The Food and Agriculture Organization of the United Nations defines primary forests as naturally regenerated forests of native tree species where there are no clearly visible indications of human activity and the ecological processes are not significantly disturbed. More than one-third (34 percent) of the world's forests are primary forests. Old-growth features include diverse tree-related structures that provide diverse wildlife habitat that increases the biodiversity of the forested ecosystem. Virgin or first-growth forests are old-growth forests that have never been logged. The concept of diverse tree structure includes multi-layered canopies and canopy gaps, greatly varying tree height ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forest Product
A forest product is any material derived from forestry for direct consumption or commercial use, such as lumber, paper, or fodder for livestock. Wood, by far the dominant product of forests, is used for many purposes, such as wood fuel (e.g. in form of firewood or charcoal) or the finished structural materials used for the construction of buildings, or as a raw material, in the form of wood pulp, that is used in the production of paper. All other non-wood products derived from forest resources, comprising a broad variety of other forest products, are collectively described as non-timber forest products (NTFP). Non-timber forest products are viewed to have fewer negative effects on forest ecosystem when providing income sources for local community. Globally, about 1.15 billion ha of forest is managed primarily for the production of wood and non-wood forest products. In addition, 749 million is designated for multiple use, which often includes production. Worldwide, the area of fore ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anping District
Anping District is a district of Tainan, Taiwan. In March 2012, it was named one of the ''Top 10 Small Tourist Towns'' by the Tourism Bureau of Taiwan. It is home to 67,263 people. Name The older place name of Tayouan derives from the ethnonym of a nearby Taiwanese aboriginal tribe, and was written by the Dutch and Portuguese variously as ''Taiouwang'', ''Tayowan'', etc. In his translations of Dutch records, missionary William Campbell used the variant ''Tayouan'' and wrote that ''Taoan'' and ''Taiwan'' also occur. As Dutch spelling varied greatly at the time (see History of Dutch orthography), other variants may be seen. The name was also transliterated into Chinese characters variously as , , , , and . After the Dutch were ousted by Koxinga, Han immigrants renamed the area "Anping" after the Anping Bridge in Quanzhou, Fujian. Soon after Qing rule was established in 1683, the name "Taiwan" () was officially used to refer to the whole island with the establishment of ...

Chemical Industry
The chemical industry comprises the companies that produce industrial chemicals. Central to the modern world economy, it converts raw materials (oil, natural gas, air, water, metals, and minerals) into more than 70,000 different products. The plastics industry contains some overlap, as some chemical companies produce plastics as well as chemicals. Various professionals are involved in the chemical industry including chemical engineers, chemists and lab technicians. History Although chemicals were made and used throughout history, the birth of the heavy chemical industry (production of chemicals in large quantities for a variety of uses) coincided with the beginnings of the Industrial Revolution. Industrial Revolution One of the first chemicals to be produced in large amounts through industrial processes was sulfuric acid. In 1736 pharmacist Joshua Ward developed a process for its production that involved heating saltpeter, allowing the sulfur to oxidize and combine with water ...

Supply And Demand
In microeconomics, supply and demand is an economic model of price determination in a Market (economics), market. It postulates that, Ceteris paribus, holding all else equal, in a perfect competition, competitive market, the unit price for a particular Good (economics), good, or other traded item such as Labour supply, labor or Market liquidity, liquid financial assets, will vary until it settles at a point where the quantity demanded (at the current price) will equal the quantity supplied (at the current price), resulting in an economic equilibrium for price and quantity transacted. The concept of supply and demand forms the theoretical basis of modern economics. In macroeconomics, as well, the AD–AS model, aggregate demand-aggregate supply model has been used to depict how the quantity of real GDP, total output and the aggregate price level may be determined in equilibrium.

Empire Of Japan
The also known as the Japanese Empire or Imperial Japan, was a historical nation-state and great power that existed from the Meiji Restoration in 1868 until the enactment of the post-World War II 1947 constitution and subsequent formation of modern Japan. It encompassed the Japanese archipelago and several colonies, protectorates, mandates, and other territories. Under the slogans of and following the Boshin War and restoration of power to the Emperor from the Shogun, Japan underwent a period of industrialization and militarization, the Meiji Restoration, which is often regarded as the fastest modernisation of any country to date. All of these aspects contributed to Japan's emergence as a great power and the establishment of a colonial empire following the First Sino-Japanese War, the Boxer Rebellion, the Russo-Japanese War, and World War I. Economic and political turmoil in the 1920s, including the Great Depression, led to the rise of militarism, nationa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Total Synthesis
Total synthesis is the complete chemical synthesis of a complex molecule, often a natural product, from simple, commercially-available precursors. It usually refers to a process not involving the aid of biological processes, which distinguishes it from semisynthesis. Syntheses may sometimes conclude at a precursor with further known synthetic pathways to a target molecule, in which case it is known as a formal synthesis. Total synthesis target molecules can be natural products, medicinally-important active ingredients, known intermediates, or molecules of theoretical interest. Total synthesis targets can also be organometallic or inorganic, though these are rarely encountered. Total synthesis projects often require a wide diversity of reactions and reagents, and subsequently requires broad chemical knowledge and training to be successful. Often, the aim is to discover a new route of synthesis for a target molecule for which there already exist known routes. Sometimes, however, no ...

Taiwan Acacia
''Acacia confusa'' is a perennial tree native to South-East Asia. Some common names for it are acacia petit feuille, Ayangile, small Philippine acacia, Formosa acacia (Taiwan acacia), Philippine Wattle, and Formosan koa. It grows to a height of 15 m. The tree has become very common in many tropical Pacific areas, including Hawaii, where the species is considered invasive. Uses The wood has a density of about 0.75 g/cm3. In Taiwan, its wood was used to make support beams for underground mines. Acacia confusa is challenging to work and for this reason was traditionally burned as firewood or turned into charcoal in Taiwan. In later years it was exported to China to be made into wood flooring for the American market. At its height Taiwan exported more than 1,000 containers of Taiwan acacia to China. More recently it has been used domestically to produce high value wood products like musical instruments, furniture, and bathtubs. The wood is also converted to charcoal for family use. ...

Deforestation In Taiwan
Deforestation in Taiwan is the changes on the forested area in the island due to economy factors, such as agriculture, urban expansion etc. In 1904–2015, Taiwan has a net annual forest area change rate of 34 km2. History The changes in forest area of Taiwan is divided into several periods. First period The earliest documented period was the first period in 1904–1950, roughly coincided with the later stage of Japanese rule in Taiwan. In 1926, 64% of Taiwan's land was covered in forest. However, many new agricultural land were created in western lowland of Taiwan. Second period The second period which in 1956–1993, which coincided with the early era of Kuomintang government, saw a sharp increase in built-up area where it consumed forest areas around major big cities and towns. In 1989, the government issued a ban on the logging of primeval forests. Third period The third period in 1995–2015, saw major afforestation made and forested land reached its peak at 67% in 2010.

Agriculture In Taiwan
Agriculture is one of the main industries in Taiwan. It contributes to the food security, rural development and conservation of Taiwan. Around 24% of Taiwan's land is used for farming. Taiwan is a global leader in vertical farming and agritourism. History Prehistory Agriculture has been an important sector of Taiwanese life since ages ago. From archaeological sites in Changbin Township, Taitung County, since Paleolithic Age around 30,000-50,000 years ago, people hunted, fished and gathered. Only in the Neolithic Age around 5,000-2,000 years ago, did people began to live their sedentary lifestyle where they grew rice and other crops and domesticated animals. During the Iron Age around 2,000 years ago, people in the northern coast of Taiwan began to make iron tools and food production increased significantly. In the 17th century, people from China began to migrate to Taiwan where they fished, hunted and grew crops. Most of them settled in the area around Tainan. Dutch Formosa ...

Urban Expansion
Urban sprawl (also known as suburban sprawl or urban encroachment) is defined as "the spreading of urban developments (such as houses and shopping centers) on undeveloped land near a city." Urban sprawl has been described as the unrestricted growth in many urban areas of housing, commercial development, and roads over large expanses of land, with little concern for urban planning. In addition to describing a special form of urbanization, the term also relates to the social and environmental consequences associated with this development. Medieval suburbs suffered from loss of protection of city walls, before the advent of industrial warfare. Modern disadvantages and costs include increased travel time, transport costs, pollution, and destruction of the countryside. The cost of building urban infrastructure for new developments is hardly ever recouped through property taxes, amounting to a subsidy for the developers and new residents at the expense of existing property taxpayers.
