Open Burning Of Waste
The open burning of waste is a disposal method of waste or garbage. It is a disposal method used globally, but often used in low and middle-income countries that lack adequate waste disposal infrastructure. Numerous governments and institutions have identified the open burning of waste as a major contributor to greenhouse gas emissions. It also poses health risks with the cocktail of air pollutants often created when waste is burned in an open air environment. At COP26 open waste burning was raised as a major contributor to climate change. It produces a wide range of atmospheric pollutants including short lived climate pollutants (SLCPs), such as black carbon (BC). BC emissions are a major source of fine particulate matter, with a climate change impact up to 5,000 greater than . Background The United Nations has raised concerns about the amount of black carbon and methane produced from open burning as a method of waste disposal. Many cities and regions suffer with air pollution an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Concession (contract)
A concession or concession agreement is a grant of rights, land, property, or facility by a government, local authority, corporation, individual or other legal entity. Public services such as water supply may be operated as a concession. In the case of a public service concession, a private company enters into an agreement with the government to have the exclusive right to operate, maintain and carry out investment in a public utility (such as a water privatisation) for a given number of years. Other forms of contracts between public and private entities, namely lease contract and management contract (in the water sector often called by the French term ''affermage''), are closely related but differ from a concession in the rights of the operator and its remuneration. A lease gives a company the right to operate and maintain a public utility, but investment remains the responsibility of the public. Under a management contract the operator will collect the revenue only on behalf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Glaciers In Bolivia Melting Away (Copernicus)
A glacier (; or ) is a persistent body of dense ice, a form of rock, that is constantly moving downhill under its own weight. A glacier forms where the accumulation of snow exceeds its Ablation#Glaciology, ablation over many years, often centuries. It acquires distinguishing features, such as crevasses and seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land“Glacier, N., Pronunciation.” Oxford English Dictionary, Oxford University Press, Oxford UP, June 2024, https://doi.org/10.1093/OED/7553486115. Accessed 25 Jan. 2025. and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water.

Air Pollution
Air pollution is the presence of substances in the Atmosphere of Earth, air that are harmful to humans, other living beings or the environment. Pollutants can be Gas, gases like Ground-level ozone, ozone or nitrogen oxides or small particles like soot and dust. It affects both outdoor air and indoor air. Natural sources of air pollution include Wildfire, wildfires, Dust storm, dust storms, and Volcanic eruption, volcanic eruptions. Indoor air pollution is often Energy poverty and cooking, caused by the use of biomass (e.g. wood) for cooking and heating. Outdoor air pollution comes from some industrial processes, the burning of Fossil fuel, fossil fuels for electricity and transport, waste management and agriculture. Many of the contributors of local air pollution, especially the burning of fossil fuels, also cause greenhouse gas emissions that cause climate change, global warming. Air pollution causes around 7 or 8 million deaths each year. It is a significant risk factor for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
