The air pollution generated in November 2024 in India and Pakistan was regarded by climate researchers as an unprecedented intensification of the region's annual pollution cycle. [2] NASA satellite imaging showed a continuous cloud of smog that extended across the majority of eastern and northern Pakistan, as well as northwestern India.
Over the past decade air pollution has increased in India significantly. Asthma is the most common health problem faced by Indians and it accounts for more than half of the health issues caused by air pollution. [43] [44] Air pollution is believed to be one of the key factors in accelerating the onset of Alzheimer's disease in India. [45]
Air pollution is usually concentrated in densely populated metropolitan areas, especially in developing countries where cities are experiencing rapid growth and environmental regulations are relatively lax or nonexistent. Urbanization leads to a rapid rise in premature mortality due to air pollution in fast-growing tropical cities. [321]
Humans are the driving force behind urban ecology and influence the environment in a variety of ways - urbanization being a key example. Urbanization is tied to social, economic and environmental processes. There are six core aspects: air pollution, ecosystems, land use, biogeochemical cycles, water pollution, solid waste management, and the ...
The urban environment has two atmosphere layers, besides the planetary boundary layer (PBL) outside and extending well above the city: (1) The urban boundary layer is due to the spatially integrated heat and moisture exchanges between the city and its overlying air. (2) The surface of the city corresponds to the level of the urban canopy layer.
Mobile source air pollution – Air pollution emitted by motor vehicles, airplanes, locomotives, and other engines; Planned obsolescence – Policy of planning or designing a product with an artificially limited useful life; Remote work – Employees working from any location; Service life – Period of time where an object can fulfill a function
Urban geography is the subdiscipline of geography that derives from a study of cities and urban processes. Urban geographers and urbanists [1] examine various aspects of urban life and the built environment. Scholars, activists, and the public have participated in, studied, and critiqued flows of economic and natural resources, human and non ...
In the World Health Organization's (WHO) ranking of cities by air pollution, Kolkata ranks 25th among a total of 1100 cities. [4] Air pollution is high in Kolkata despite the city's relatively low rates of car ownership, compared to other large Indian cities, [5] and its strong public transport. It may be possible to reduce Kolkata's energy ...
