BengalBengal (bɛnˈɡɔːl ; বাংলা/বঙ্গ, ˈbɔŋgo) is a historical geographical, ethnolinguistic and cultural term referring to the eastern part of the Indian subcontinent at the apex of the Bay of Bengal. The region of Bengal proper is divided between modern-day Bangladesh and the Indian state of West Bengal. The Indian states of Assam and Tripura have a sizeable Bengali population. A large Bengali diaspora exists across the world. Bengali is the sixth-most spoken language in the world.
Bengal PresidencyThe Bengal Presidency, officially the Presidency of Fort William in Bengal and later Bengal Province, was a subdivision of British India. At the height of its territorial jurisdiction, it covered large parts of what is now South Asia and Southeast Asia. Bengal proper covered the ethno-linguistic region of Bengal (present-day Bangladesh and the Indian state of West Bengal). Calcutta, the city which grew around Fort William, was the capital of the Bengal Presidency.
Bengal SultanateThe Bengal Sultanate (Middle Bengali: শাহী বাঙ্গালা Shahī Baṅgala, Classical Persian: Saltanat-e-Bangālah) was a Sunni Muslim empire based in Bengal for much of the 14th, 15th and 16th centuries. It was the dominant power of the Ganges–Brahmaputra Delta, with a network of mint towns spread across the region. The Bengal Sultanate had a circle of vassal states in the subcontinent, including parts of Odisha in the southwest, Arakan in the southeast, and Tripura in the east.
North BengalNorth Bengal (উত্তরবঙ্গ/উত্তর বাংলা) is a term used for the north-western part of Bangladesh and northern part of West Bengal. The Bangladesh part denotes the Rajshahi Division and Rangpur Division. Generally, it is the area lying west of Jamuna River and north of Padma River and includes the Barind Tract. The West Bengal part denotes Jalpaiguri Division (Alipurduar, Cooch Behar, Darjeeling, Jalpaiguri, and Kalimpong) and the Malda division (Uttar Dinajpur, Dakshin Dinajpur, and Malda) together.
West BengalWest Bengal (bɛnˈɡɔːl, Bengali: Poshchim Bongo, ˈpoʃtʃim ˈbɔŋɡo, abbr. WB) is a state in the eastern portion of India. It is situated along the Bay of Bengal, along with a population of over 91 million inhabitants within an area of as of 2011. The population estimate as of 2023 is 102,552,787. West Bengal is the fourth-most populous and thirteenth-largest state by area in India, as well as the eighth-most populous country subdivision of the world.
History of BengalThe history of Bengal is intertwined with the history of the broader Indian subcontinent and the surrounding regions of South Asia and Southeast Asia. It includes modern-day Bangladesh and the Indian states of West Bengal, Tripura and Assam's Karimganj district, located in the eastern part of the Indian subcontinent, at the apex of the Bay of Bengal and dominated by the fertile Ganges delta. The region was known to the ancient Greeks and Romans as Gangaridai, a powerful kingdom whose war elephant forces led the withdrawal of Alexander the Great from India.
CholeraCholera ('kɒlərə) is an infection of the small intestine by some strains of the bacterium Vibrio cholerae. Symptoms may range from none, to mild, to severe. The classic symptom is large amounts of watery diarrhea that lasts a few days. Vomiting and muscle cramps may also occur. Diarrhea can be so severe that it leads within hours to severe dehydration and electrolyte imbalance. This may result in sunken eyes, cold skin, decreased skin elasticity, and wrinkling of the hands and feet. Dehydration can cause the skin to turn bluish.
ClimateClimate is the long-term weather pattern in a region, typically averaged over 30 years. More rigorously, it is the mean and variability of meteorological variables over a time spanning from months to millions of years. Some of the meteorological variables that are commonly measured are temperature, humidity, atmospheric pressure, wind, and precipitation. In a broader sense, climate is the state of the components of the climate system, including the atmosphere, hydrosphere, cryosphere, lithosphere and biosphere and the interactions between them.
Likelihood functionIn statistical inference, the likelihood function quantifies the plausibility of parameter values characterizing a statistical model in light of observed data. Its most typical usage is to compare possible parameter values (under a fixed set of observations and a particular model), where higher values of likelihood are preferred because they correspond to more probable parameter values.
Water resourcesWater resources are natural resources of water that are potentially useful for humans, for example as a source of drinking water supply or irrigation water. 97% of the water on Earth is salt water and only three percent is fresh water; slightly over two-thirds of this is frozen in glaciers and polar ice caps. The remaining unfrozen freshwater is found mainly as groundwater, with only a small fraction present above ground or in the air. Natural sources of fresh water include surface water, under river flow, groundwater and frozen water.
Climate changeIn common usage, climate change describes global warming—the ongoing increase in global average temperature—and its effects on Earth's climate system. Climate change in a broader sense also includes previous long-term changes to Earth's climate. The current rise in global average temperature is more rapid than previous changes, and is primarily caused by humans burning fossil fuels. Fossil fuel use, deforestation, and some agricultural and industrial practices increase greenhouse gases, notably carbon dioxide and methane.
History of choleraSeven cholera pandemics have occurred in the past 200 years, with the first pandemic originating in India in 1817. The seventh cholera pandemic is officially a current pandemic and has been ongoing since 1961, according to a World Health Organization factsheet in March 2022. Additionally, there have been many documented major local cholera outbreaks, such as a 1991–1994 outbreak in South America and, more recently, the 2016–2021 Yemen cholera outbreak.
Water scarcityWater scarcity (closely related to water stress or water crisis) is the lack of fresh water resources to meet the standard water demand. There are two types of water scarcity namely physical and economic water scarcity. Physical water scarcity is where there is not enough water to meet all demands, including that needed for ecosystems to function. Arid areas for example Central and West Asia, and North Africa often experience physical water scarcity.
Architecture of BengalThe Architecture of Bengal, which comprises the modern country of Bangladesh and the Indian states of West Bengal, Tripura and Assam's Barak Valley, has a long and rich history, blending indigenous elements from the Indian subcontinent, with influences from different parts of the world. The most famous monument built by the Pala emperors was the Grand Vihara of Somapura, now a UNESCO World Heritage Site. Historians believe Somapura was a model for the architects of Angkor Wat in Cambodia.
Bottled waterBottled water is drinking water (e.g., well water, distilled water, mineral water, or spring water) packaged in plastic or glass water bottles. Bottled water may be carbonated or not. Sizes range from small single serving bottles to large carboys for water coolers. Although vessels to bottle and transport water were part of the earliest human civilizations, bottling water began in the United Kingdom with the first water bottling at the Holy Well in 1622.
Nawabs of BengalThe Nawab of Bengal (বাংলার নবাব, ) was the hereditary ruler of Bengal Subah in Mughal India. In the early 18th-century, the Nawab of Bengal was the de facto independent ruler of the three regions of Bengal, Bihar and Orissa which constitute the modern-day sovereign country of Bangladesh and the Indian states of West Bengal, Bihar and Odisha. They are often referred to as the Nawab of Bengal, Bihar and Orissa (বাংলা, বিহার ও উড়িষ্যার নবাব). The Nawabs were based in Murshidabad which was centrally located within Bengal, Bihar, and Odisha.
Multiple comparisons problemIn statistics, the multiple comparisons, multiplicity or multiple testing problem occurs when one considers a set of statistical inferences simultaneously or infers a subset of parameters selected based on the observed values. The more inferences are made, the more likely erroneous inferences become. Several statistical techniques have been developed to address that problem, typically by requiring a stricter significance threshold for individual comparisons, so as to compensate for the number of inferences being made.
Climate change denialClimate change denial or global warming denial is dismissal or unwarranted doubt that contradicts the scientific consensus on climate change. Those promoting denial commonly use rhetorical tactics to give the appearance of a scientific controversy where there is none. Climate change denial includes doubts to the extent of how much climate change is caused by humans, its effects on nature and human society, and the potential of adaptation to global warming by human actions.
Abrupt climate changeAn abrupt climate change occurs when the climate system is forced to transition at a rate that is determined by the climate system energy-balance, and which is more rapid than the rate of change of the external forcing, though it may include sudden forcing events such as meteorite impacts. Abrupt climate change therefore is a variation beyond the variability of a climate. Past events include the end of the Carboniferous Rainforest Collapse, Younger Dryas, Dansgaard-Oeschger events, Heinrich events and possibly also the Paleocene–Eocene Thermal Maximum.
Climate modelNumerical climate models use quantitative methods to simulate the interactions of the important drivers of climate, including atmosphere, oceans, land surface and ice. They are used for a variety of purposes from study of the dynamics of the climate system to projections of future climate. Climate models may also be qualitative (i.e. not numerical) models and also narratives, largely descriptive, of possible futures.
