Deforestation or forest clearance is the removal and destruction of a forest or stand of trees from land that is then converted to non-forest use. Deforestation can involve conversion of forest land to farms, ranches, or urban use. About 31% of Earth's land surface is covered by forests at present. This is one-third less than the forest cover before the expansion of agriculture, with half of that loss occurring in the last century. Between 15 million to 18 million hectares of forest, an area the size of Bangladesh, are destroyed every year. On average 2,400 trees are cut down each minute. Estimates vary widely as to the extent of deforestation in the tropics. In 2019, nearly a third of the overall tree cover loss, or 3.8 million hectares, occurred within humid tropical primary forests. These are areas of mature rainforest that are especially important for biodiversity and carbon storage.
The Amazon rainforest, also called Amazon jungle or Amazonia, is a moist broadleaf tropical rainforest in the Amazon biome that covers most of the Amazon basin of South America. This basin encompasses 7,000,000 km2 (2,700,000 sq mi), of which 5,500,000 km2 (2,100,000 sq mi) are covered by the rainforest. This region includes territory belonging to nine nations and 3,344 formally acknowledged indigenous territories.
Rainforests are forests characterized by a closed and continuous tree canopy, moisture-dependent vegetation, the presence of epiphytes and lianas and the absence of wildfire. Rainforests can be generally classified as tropical rainforests or temperate rainforests, but other types have been described.
Tropical rainforests are dense and warm rainforests with high rainfall typically found between 10 degrees north and south of the equator. They are a subset of the tropical forest biome that occurs roughly within the 28-degree latitudes. Tropical rainforests are a type of tropical moist broadleaf forest, that includes the more extensive seasonal tropical forests. True rainforests usually occur in tropical rainforest climates where there is no dry season – all months have an average precipitation of at least 60 mm. Seasonal tropical forests with tropical monsoon or savanna climates are sometimes included in the broader definition.
Fairfield Ludlowe High School (FLHS) is a co-educational secondary school located in Fairfield, Connecticut, United States.
Damian Ramsey (1978-2007) was a musician, poet, composer and musicologist who invented the music genre word "synthpunk" in 1999 in order to retroactively describe synthesizer-based punk bands from 1977-1984. He documented this obscure and relatively neglected corner of American music history on synthpunk.org from 1999-2004.
The Forests Now Declaration is a declaration that advocates using carbon credits to protect tropical forests. The Declaration was created by the Global Canopy Programme, and has been signed by over 200 NGOs, business leaders, scientists and conservationists. The Declaration was created as carbon credits from land use, land-use change and forestry were omitted from the Clean Development Mechanism for the First Commitment Period of the Kyoto Protocol despite contributing 18–25% of all emissions.
Brazil once had the highest deforestation rate in the world and in 2005 still had the largest area of forest removed annually. Since 1970, over 700,000 square kilometres (270,000 sq mi) of the Amazon rainforest have been destroyed. In 2001, the Amazon was approximately 5,400,000 square kilometres (2,100,000 sq mi), which is only 87% of the Amazon's original size. According to official data, about 729,000 km² have already been deforested in the Amazon biome, which corresponds to 17% of the total. 300,000 km² have been deforested in the last 20 years.
Deforestation in Nigeria refers to the extensive and rapid clearing of forests within the borders of Nigeria. This environmental issue has significant impacts on both local and global scales.
The 2004 United States Senate election in Indiana was held on November 2, 2004. Incumbent Democratic U.S. Senator Evan Bayh won re-election to a second term. To date, this was the last time the Democrats have won the Class 3 Senate seat from Indiana. Bayh won 86 of the state's 92 counties.
Larry Bowler was a Republican politician from the State of California. He represented suburban Sacramento in the California State Assembly from 1992 until 1998.
The Amazon rainforest, spanning an area of 3,000,000 km2, is the world's largest rainforest. It encompasses the largest and most biodiverse tropical rainforest on the planet, representing over half of all rainforests. The Amazon region includes the territories of nine nations, with Brazil containing the majority (60%), followed by Peru (13%), Colombia (10%), and smaller portions in Venezuela, Ecuador, Bolivia, Guyana, Suriname, and French Guiana.
Tropical ecology is the study of the relationships between the biotic and abiotic components of the tropics, or the area of the Earth that lies between the Tropic of Cancer and the Tropic of Capricorn. The tropical climate experiences hot, humid weather and rainfall year-round. While many might associate the region solely with the rainforests, the tropics are home to a wide variety of ecosystems that boast a great wealth of biodiversity, from exotic animal species to seldom-found flora. Tropical ecology began with the work of early English naturalists and eventually saw the establishment of research stations throughout the tropics devoted to exploring and documenting these exotic landscapes. The burgeoning ecological study of the tropics has led to increased conservation education and programs devoted to the climate. Tropical ecology provides a wealth of natural resources to humans, this includes contributing to the carbon cycle, with the ability to store 50% of carbon emissions as well as turnover 40% of global oxygen. However, despite the natural services provided by tropical ecology, deforestation is a threat of tropical rainforests. Any plant of interest can be exploited for commercial reasons and extraction of these specific plant species can be at a rapid rate without time for healthy regeneration. Most of the global plant biodiversity is hosted in tropical areas, however studies in this area is mostly covered by scientist from Northern countries. Inclusion of scientist from countries where rainforest is present is heavily encouraged because it extends global knowledge and research which advances scientific contributions, benefiting tropical ecology.
The 2002 United States Senate election in Tennessee was held on November 5, 2002. Incumbent Republican U.S. Senator Fred Thompson decided to retire. Former Republican Governor Lamar Alexander won the open seat.
Rates and causes of deforestation vary from region to region around the world. In 2009, two-thirds of the world's forests were located in just 10 countries: Russia, Brazil, Canada, the United States, China, Australia, the Democratic Republic of the Congo, Indonesia, India, and Peru.
Akure Forest Reserve is a protected area in southwest Nigeria, covering 66 km2 (25 sq mi). The Akure Forest Reserve, established in 1948 and spanning approximately 32 hectares. It was created with the primary aim of safeguarding the genetic diversity of the forest ecosystem. About 11.73% is estimated to be cleared for cocoa farming and other food crops. Aponmu and Owena Yoruba speaking communities owned the forest, though, there are also minor settlements surrounding the forest. They include Ipogun, Kajola/ Aponmu, Kajola, Ago Petesi, Akika Camp, Owena Town, Ibutitan/Ilaro Camp, Elemo Igbara Oke Camp and Owena Water new Dam.
Forest restoration is defined as “actions to re-instate ecological processes, which accelerate recovery of forest structure, ecological functioning and biodiversity levels towards those typical of climax forest” i.e. the end-stage of natural forest succession. Climax forests are relatively stable ecosystems that have developed the maximum biomass, structural complexity and species diversity that are possible within the limits imposed by climate and soil and without continued disturbance from humans. Climax forest is therefore the target ecosystem, which defines the ultimate aim of forest restoration. Since climate is a major factor that determines climax forest composition, global climate change may result in changing restoration aims. Additionally, the potential impacts of climate change on restoration goals must be taken into account, as changes in temperature and precipitation patterns may alter the composition and distribution of climax forests.
Deforestation is a primary contributor to climate change, and climate change affects the health of forests. Land use change, especially in the form of deforestation, is the second largest source of carbon dioxide emissions from human activities, after the burning of fossil fuels. Greenhouse gases are emitted from deforestation during the burning of forest biomass and decomposition of remaining plant material and soil carbon. Global models and national greenhouse gas inventories give similar results for deforestation emissions. As of 2019, deforestation is responsible for about 11% of global greenhouse gas emissions. Carbon emissions from tropical deforestation are accelerating.
The biogeographic regionalization of Earth's terrestrial biodiversity, known as Terrestrial Ecoregions of the World (TEOW), is made up of 867 ecoregions that are divided into 14 biomes. In addition to offering a comprehensive map of terrestrial biodiversity, TEOW also provides a global species database for ecological analyses and priority setting, a logical biogeographic framework for large-scale conservation strategies, a map for enhancing biogeographic literacy, and a foundation for the Global 200.
