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. [4] [5] Greenhouse gases are emitted from deforestation during the burning of forest biomass and decomposition of remaining plant material and soil carbon.
Deforestation is defined as the conversion of forest to other land uses (regardless of whether it is human-induced). [14] Deforestation and forest area net change are not the same: the latter is the sum of all forest losses (deforestation) and all forest gains (forest expansion) in a given period. Net change, therefore, can be positive or ...
In 2024, deforestation in Colombia's Amazon region has increased by 40% during the first quarter compared to the same period last year, according to a report. [152] This rise in deforestation is occurring amidst the influence of a strong El Niño weather phenomenon, causing dry and hot conditions that have led to droughts and fires throughout ...
Deforestation is the main land use change contributor to global warming, [62] Between 1750 and 2007, about one-third of anthropogenic CO 2 emissions were from changes in land use - primarily from the decline in forest area and the growth in agricultural land. [63] primarily deforestation.
Drivers of deforestation and forest degradation by region, 2000–2010, from the Food and Agriculture Organization publication The State of the World's Forests 2020. Forests, biodiversity and people – In brief [3] Deforestation is much worse than forest degradation, but it is clear and visible.
Amazon deforestation jumped by 69% in 2008 compared to 2007's twelve months, according to official government data. [ 57 ] However, a 30 January 2009 New York Times article stated, "By one estimate, for every acre of rainforest cut down each year, more than 50 acres of new forest are growing in the tropics."
In other words, what do people lose out on with the removal of a given habitat? A country may increase its food supply by converting forest land to row-crop agriculture, but the value of the same land may be much larger when it can supply natural resources or services such as clean water, timber, ecotourism, or flood regulation and drought control.
This is an alphabetical list of environmental issues, harmful aspects of human activity on the biophysical environment. They are loosely divided into causes, effects and mitigation, noting that effects are interconnected and can cause new effects.
